What is demolition in construction. Features and types of dismantling works. About the manual method

There are various ways to dismantle various objects. In general, they can be divided into three general groups:

The choice of method for dismantling objects depends on their design features, location, local infrastructure and layout of technical communications. The purpose of the dismantling should also be taken into account: for example, in some cases the foundation of a building being dismantled may serve as the basis for the construction of a new structure and must be preserved.

Factors for choosing the type of dismantling work

Demolition of building structures of various types can be complete or partial, with the preservation of certain elements. The choice of the first option is expedient if it is necessary to completely clear the land plot under the demolished structure. In the future, such a site can be used both for building up more modern buildings with new communication networks, and for building roads, squares, laying out parks, and equipping recreation areas.

Partial dismantling of buildings is used in cases where some structural elements (foundation, walls, ceilings, frame) can be used in a new building. This option is more economical, but its selection requires preliminary thorough technical expertise and analysis of the state and safety of structures.

There are a number of factors that should be taken into account when choosing a method for dismantling structures:

  • type of construction and purpose of the future construction object;
  • the location of the demolished structure and the density of the area;
  • dimensions, number of floors and type of building to be dismantled;
  • local infrastructure and communications.

Important! The dismantling of structures is a complex technological process, which can be carried out only after preliminary technical analysis and preparation.

Manual disassembly

Manual dismantling of structures is used when it is necessary to carry out particularly precise work in partial or complete dismantling of an object. This option is relevant when adjacent structures are located close to each other, which make it difficult to use special equipment and exclude blasting. The manual method of dismantling is used only when dismantling buildings with a height of no more than 5 floors.

For manual dismantling, diamond cutting technologies, work with jackhammers, various cutters, drills, hand construction tools of this type are used.

Typically, manual work is used in the partial dismantling of buildings, their restoration and major repairs.

Demolition by blasting

Domestic legislation strictly limits the types and scope of explosives. For this reason, the use of dismantling by means of blasting is quite rare. Demolition of structures in this way is allowed only if they are at a considerable distance from residential buildings and other objects that may be affected by an explosion, for example, places where combustible and explosive substances are stored, gas pipelines and other communications. With the help of explosions, large structures are usually demolished - stadiums, high-rise buildings, outdated industrial or residential complexes.

Mechanized dismantling

Demolition of structures with the help of special equipment is the most common method of dismantling. Modern equipment and machinery make it possible to quickly and efficiently dismantle buildings with a high building density of neighboring plots. Small objects up to 4 floors high are demolished by an excavator. For the demolition of structures up to 22 m high, special excavators with extended booms, as well as construction hydraulic hammers and hydraulic shears are used. It should be noted that mechanized dismantling with the help of such equipment is used only if it is necessary to completely demolish structures and clear the land.

Initially, air conditioners were used only for cooling the air, and this function is still the main one.

Dismantling works include not only the complete destruction of various structures, as a result of which damage to communications and systems is guaranteed. Depending on the characteristics of a particular facility, you can choose the appropriate type of work that provides the necessary combination of efficiency and speed.

Partial or complete dismantling

First of all, it is determined whether the building will be completely destroyed or whether it is planned to be reconstructed or improved. Depending on this, the work can be directed to complete demolition or partial dismantling.

The dismantling of the entire structure applies to:

  • various production facilities;
  • dilapidated buildings;
  • buildings in disrepair.

At the same time, if the building is in critical condition, there are destructions of the foundation and walls, then explosives are used for dismantling. They quickly destroy the structure, reducing risks to the health of workers.

With partial demolition, only various ceilings, walls, partitions, and so on are removed. That is, the structural integrity of certain parts of the structure is preserved.

How can dismantling be done?

Depending on the desired result, various methods of dismantling are selected. So the following types of work are distinguished:

  • Element-by-element dismantling is the most complex and economically beneficial type of work, in which the foundation of the structure is preserved, which serves as the basis for further construction work. Elements removed during dismantling, which are in good condition, can be reused in the future.
  • Mechanized demolition - with the help of heavy equipment, the entire structure is completely destroyed.
  • Explosive works - are used if it is necessary to demolish the structure quickly. They are distinguished by a high level of requirements for the skills of specialists performing dismantling.

There are also highly specialized approaches, including thermal and electro-hydraulic dismantling. They and some other types of work are used only in certain areas where classical solutions are impossible.

Suitable types of dismantling works are selected taking into account the specifics of the project. If the building is to be used in the future, then often the process is divided into several stages, during which all communications and support systems, walls, partitions, and so on are gradually removed.

The correct approach to dismantling can significantly reduce the cost of it and make it cost-effective.

Construction dismantling is an integral part of construction and repair work. The types of this kind of construction specialization range from the simplest dismantling of the plinth and disassembly of the built-in furniture in the apartment, ending with the industrial dismantling of enterprises and high-rise buildings.

During the preparation of the premises for repair, dismantling the elements is within the power of any person using a minimum set of tools. For example, in order to remove the baseboard when replacing the old linoleum, you will need an ordinary carpenter's ax and a nail puller. You can get rid of old paper wallpaper with a conventional spray bottle with warm water, a foam rubber sponge and a spatula. We separate the pre-moistened wallpaper from the wall with a spatula and pull it off the wall.

For a major overhaul of an apartment, when carrying out such work as: walls, pipes, you will need more serious tools: an angle grinder (popularly known as a grinder). Angle grinder is one of the main tools, without which dismantling work is simply hard to imagine. It is indispensable if you need to replace pipes (heating, water supply), as well as other metal structures that cannot be disassembled. A perforator can knock down tiles from the floor and walls. It is also used for gouging recesses and making holes when installing various plumbing equipment and electricians.

If the building has partitions or concrete ceilings to be demolished, then an ordinary household perforator is no longer enough. For these purposes, there are special "heavy" perforators and jackhammers. In rare cases, manual hydraulic shears may be used.

When dismantling wooden structures, the dismantler's arsenal should be an electric saw or chainsaw. Depending on the parameters of the work performed, saws of different power and cutting speed are used.

In industrial dismantling, a mechanized method of breaking objects is used. It is the fastest and highest quality and involves the use of heavy construction machines. Dismantlers use cranes, bulldozers, excavators. Various attachments can also be used.

And road structures are made using equipment with various attachments (hydraulic hammer, hydraulic shears-crushers, crushing bucket). When using gas welding equipment.

Demolition construction machines are very manoeuvrable and productive, which allows dismantling in densely built-up conditions, observing all necessary safety measures.

But there are cases when the demolition of buildings with the help of machines is not always effective. For example, when part of a building needs to be saved for future use, or when the facility where the work is being done is located near other buildings. In this case, manual dismantling of the building is used. In this case, it is not possible without the involvement of small-scale mechanization tools (concrete breakers, hydraulic wedges, jackhammers and manual hydraulic shears)

Another method of dismantling buildings is the method of directed explosion. In Russia, this practice is practically not used, and abroad, the dismantling of high-rise structures and buildings by explosive methods has become widespread.

Dismantling of building structures is a very serious and complex matter, which should be dealt with by professional specialists. When carrying out demolition works, increased attention should be paid to labor protection and safety at the dismantling site.

Dismantling is a process that includes dismantling, demolition or partial destruction of the building structure, carried out in connection with the unsuitability of the building or with the planning of subsequent repair measures. Work is carried out only according to the project, previously developed by a competent engineer.

When dismantling load-bearing walls, it is especially important to observe the finished project. Depending on the material from which the wall is made, the method of work is also different.

Dismantling partitions is used to increase the space in the room. It provides for the phased dismantling of non-bearing walls in order to avoid the collapse of partitions on the floor. It is also important not to damage the wiring and other communications.

Those who decide to redevelop a house, apartment, office cannot do without dismantling. It is unlikely that it will be possible to do this on your own, since the dismantling of buildings involves a time-consuming and serious process that is best entrusted to qualified workers. Professionals use special technologies that allow for the dismantling of wooden, brick, cinder block houses.

This is not an easy job that requires certain skills and abilities, and it should also be carried out only by people who have the appropriate documents confirming the permission for this process. It is necessary to prepare in advance special devices, personnel, and also take care of security measures, since the dismantling of buildings and structures is a hazardous activity.

Dismantling works quickly and efficiently

Recently, individual walls have often been dismantled, and not the entire building as a whole. Thus, the cost of the work will also depend on the material from which the wall is made. The worse the material, the cheaper the dismantling will cost. Reinforced concrete walls are considered the most expensive to maintain. In block houses, many prefer to carry out dismantling work in order to increase living space by connecting rooms with balconies. You don't have to worry about remodeling your home. The main thing is to know where the load-bearing walls are. And the removal of drywall partitions does not even require special permission. Therefore, you can safely carry out dismantling work with redevelopment of an apartment or house at your discretion.

Garbage from destruction is a mandatory consequence that dismantling works leave behind. According to the legislation, it is forbidden to dispose of such waste in household garbage containers. Therefore, after such work, it is necessary to place this garbage in special bags and take it to the place of its disposal. It is advisable to entrust the dismantling of buildings to competent workers, whose services are offered by many construction companies.

Various types of services

Today, dismantling work is carried out using a variety of devices, such as a puncher, grinder, grinder. Specialists carry out a number of works that help to carry out redevelopment of any level of complexity. This process usually includes:

  • dismantling of floors, brick and concrete partitions;
  • removal of plaster;
  • laying holes for electrical outlets;
  • removal of wallpaper, tiles;
  • dismantling of window doors;
  • disassembly of plasterboard structures.

Dismantling is a kind of pre-repair work that requires good preparation of all walls and ceilings in the room. Work is carried out in a strictly allotted time, in compliance with all laws and regulations. Therefore, before starting these activities, it is better to consult with qualified specialists.

What is demolition?

With the development of civilization, we constantly observe how cities grow and expand. For the development of the city you need a lot of space. But the growth of the city is not only in breadth. Building land is not getting cheaper, and after its purchase, a significant number of documents are drawn up in order to build something on it. Therefore, more and more often, dismantling is required, which LUGRECOTRANS LLC is always ready to carry out.

What is demolition? If you look into the dictionary, then the definition of this term is - it is dismantling, demolition of structures. But not a synonym for the word "break". You can break a sand castle or a house of cards. But dismantling is a delicate job, which sometimes requires a creative approach.

Houses constructively differ in the degree of complexity. The more complex it is, the more difficult it is to dismantle them. The city needs the demolition of old buildings as much as the construction of new ones. If the building is outdated, a new one is erected in place of the old one. This is necessary for various purposes, one of which is that the face of the city should not “age”. Dismantling is no easy task. For the solution of which workers with experience are needed, special equipment with jewelry navigational accuracy, and a solution that combines these components. As a result, destruction becomes not destructive, but constructive.

You can dismantle a building in three main ways.

The first way is gentle. This is a simple demolition of an outdated building. It uses manual work. The sparing method is used when a wooden structure is demolished, or when the building structure needs to be reused.

The second way is the demolition of the building with the help of machinery. It is common, but you can’t call it delicate anymore. It represents the destruction of the structure of the building, which involves excavators and other heavy equipment.

The third way is an explosion. It is the fastest and most effective, but requires careful calculation and professionalism.

In addition to partial and complete dismantling of buildings, it is possible to dismantle structures made of wood, metal, as well as industrial facilities. Consider each of these types of demolition.

Demolition of wooden structures is the easiest. The tree has individual qualities that allow dismantling quickly and without problems. It is also cheap - the cost is proportional to the amount of effort expended on it.

Dismantling of metal structures is the demolition of structures and manual disassembly of what remains. Modern metal structures are light and mobile, so the dismantled metal structure, if necessary, is assembled elsewhere. It is important to carefully carry out the demolition in accordance with the documentation. During transportation, metal structures are packed to avoid damage.

Dismantling of buildings distinguish between partial and complete. Partial includes the demolition of walls, partitions and ceilings. If the building is in an extremely dilapidated state, resort to the help of an explosion. The dismantling of the foundation is a task of increased complexity. After all, it is built in the ground, and its disassembly requires special equipment and experienced employees.

Dismantling of industrial facilities has features. An industrial facility is not a single building, but a complex that includes workshops, hangars or warehouses. After the demolition of such structures, a large amount of construction debris remains. The removal of this garbage is part of the work of LUGREKOTRANS LLC.

Before starting work, a thoughtful and calculated decision is first made. Even the smallest mistake is dangerous as a complete failure. But with LLC "LUGREKOTRANS" you do not have to worry - we will provide the result at the highest level. After all, before starting work, the documentation about the dismantled object is carefully studied. An analysis of the area is carried out, the structures are carefully examined, and a decision is made on the method of demolition. Sometimes making such a decision is a complex process, but the team's experience in thinking creatively makes it “honed” to the millimeter.
