Description

The invention relates to the construction and relates to the construction of buried structures for civil, industrial and hydraulic purposes.

There is a known method of erecting a buried structure, including the implementation of enclosing walls using the wall in soil method and the phased development of a foundation pit over the entire area with the installation of spacers between the enclosing walls at the end of each stage.

A disadvantage of the known method is the high material consumption of the structure, due to the need to significantly deepen the enclosing walls below the bottom of the structure to ensure stability.

Closest to the invention is a method of erecting a recessed structure, including the implementation of enclosing walls using the wall in soil method, concreting part of the bottom, installing temporary spacers. Placed between the walls and part of the bottom, installing internal structures, adding concrete to the bottom and disassembling temporary spacers.

A disadvantage of the known method is the high material consumption of the structure, due to the need to deepen the enclosing walls below the bottom of the structure and the use of temporary structures of spacers that are not inventory, as well as the high complexity of the construction of the structure associated with

the manufacture of temporary spacer elements, their installation and disassembly.

The purpose of the invention is to reduce the material consumption of the structure and the complexity of its construction.

This goal is achieved by the fact that in the method of erecting a buried structure, including the execution of enclosing walls using the wall in soil method, excavating a pit, concreting a part of the bottom, installing fastening of the enclosing walls as spacers placed between the walls and the part of the bottom, adding the bottom and mounting internal structures, the development of the pit is carried out in two stages, while at the first stage the pit is developed to the design level with free stable slopes with the abandonment of soil gp, spacers mounted horizontally through the ground and concreted the prism part of the bottom, and then mount the upper overlap with the opening, developing a second phase pit removed soil through an opening in the upper ceiling, and bottom dobetoniruyut, omonolichiva spacers.

The drawing shows a view of a recessed structure after the development of the foundation pit of the first stage, installation of spacer elements, part of the bottom and installation of the upper ceiling with the opening.

A method of erecting a recessed structure includes the implementation of enclosing walls 1 using the wall in soil method, wherein the deepening of the walls, their thickness and reinforcement are taken into account based on operational loads. Then, foundation pit 2 of the first stage is opened with free slopes, the laying of which is determined from the condition of ensuring their stability. At a high level, the water table is lowered. From the pit 2, horizontal spacer elements 4 are brought to the walls 1 through soil prisms 3 by drilling, punching or another known method, a part of the bottom 5 is concreted at the bottom of the pit, which combines the spacer elements 4, and also the upper ceiling 6 is mounted with the opening 7 After hardening the concrete of part of the bottom 5, part of the internal structures 8 of the buried structure can be erected.

At the second stage, soil prisms 3 are developed by removing soil through the opening 7

the upper floor 6, and the bottom is concreted, monopolizing the spacer elements 4. After hardening the concrete, the bottom continues to mount internal structures. If the structure has several floors, they are mounted as the foundation pit is developed in the second stage, but with obligatory leaving openings to remove the soil of the underlying excavations.

The walls of the buried structure perceive active pressure from the surrounding soil mass. The implementation of the part of the bottom with spacers and upper floor according to the proposed

Claims (1)

the method before the final development of the pit provides a reduction in the bending moments acting in the walls during the construction period, which, in turn, allows to reduce the thickness of the walls and their depth below the base of the structure and thereby reduce the consumption of concrete, reinforcement and the associated labor costs . In addition, the spacer elements and the upper ceiling not only ensure the stability of the walls during the construction period, but also are the supporting structures of the structure, which eliminates the use of temporary spacer elements and the associated labor costs in their manufacture, installation and dismantling. SUMMARY OF THE INVENTION A method for erecting a recessed structure, the method comprising walling in a ground, development of a pit, concreting of a part of the bottom, installation of fastening of enclosing walls in the form of spacers placed between the walls and a part of the bottom, installation of internal structures and concreting of a solid bottom, characterized in that in order to reduce the material consumption of the structure and the complexity of its construction, the development of the pit was carried out yut in two stages, with the first the pit stage is developed up to the design mark with free stable slopes leaving soil prisms, spacer elements are installed horizontally through the soil prisms, after which concreted part of the bottom, mount the upper floor with the opening, develop a foundation pit, of the second stage, remove the soil through the opening in the upper floor and concrete the bottom, monopolizing the spacer elements.
