The invention relates to the construction and construction of structures in water-saturated soils.

There is a method of erecting an underground part of a structure, including disassembling the contour of a trench structure under mud protection, building enclosing walls, developing the soil inside the structure from under the water, and making the bottom using the underwater concreting method 1.

This method of erection of submerged structures requires significant labor, energy and material resources and does not always exclude the influx and the squeezing of soil into the structure during the development of the excavation and bottom structure.

The closest to the invention is a method of erecting an underground part of a structure, which consists in building trenches along the contour of the building under protection of the clay solution, making walls above the wall, developing the excavation pit inside the construction pit before and underwater pumping out of the excavation pit placed on (Cho bottom reverse filter, loaded with i.-iiepxy riprap, then pumping 1I) d through tubular wells, placed 11,1, 10 in the reverse filter, drain the pit 11 simultaneously with concrete iem dnini liiicyxo continue pumping water from trubch; n .. | .x to j) dtsev left in reverse fp.1yre 2.

The well-known waterpick removal method is the possibility of ground influx into the riponec14- underwater excavation pit, as well as a large consumption of filter material and additional consumption of reinforced concrete to increase the height of the walls of the structure, which is necessary both to form the pit for the reverse filter and to load it from stone and for inserting the wall of the structure into the ground below the bottom of the open pit to obtain a guarantee against breaking through the surrounding water into the pit.

The purpose of the invention is to simplify and increase the reliability of the method.

The goal is achieved by the fact that coiJiacHo method of erection of podzsell (JI hours of construction in water-saturated soils, I’m working on the design of the trench under the protection of the clay solution, the construction of enclosing walls in the trench, the development of the pit inside the contour of the building, laying the filter material with the placement of vertical tubular wells in it, pumping of underground water through vertical tubular wells and concreting the bottom, and after the trench is developed in it, is installed along its inner wall vertical tubes with perforations at the lower ends.

and the filtering material is placed in the bottom of the trench and before the enclosing walls are loaded, the filtering material is loaded with cement slurry and its claying is carried out by feeding the water-air mixture into the tubes and pumping the mud through tubular wells, and the groundwater is pumped out inside the building circuit simultaneously with the development excavation and subsequent concreting the bottom.

FIG. 1 shows a trench with a tubular well and a clay pipe, section; in fig. 2 - the version is located and tubular wells and tubes for melting, plan; in fig. 3 - trainee with laid filtration material, cement back loading and wall of the structure, section; in fig. 4 wall construction at the time of excavation between the walls, a cross-section; in fig. 5 - the same, at the time of the bottom.

The method is implemented as follows. In the trench 1, otd. Under the protection of the clay solution along the contour of the structure, tubular wells 2 are installed at the outer wall of the trench with filters in the bottom m end. Along the inner wall of the trench, pipes 3 are installed that are not perforated in the lower part to the height of the packing of the filtering material 4. Distance

between the tubes 3 is determined so that the scab emerges from the holes of their perforated part, cover the distance between them. Then, using the method vertically, one pipe, one pipe, and one with filtering clay, one filter material is placed in section 1 with filter 1. Filter material

4 is loaded with a layer of cement slurry 5. The thickness and quality of the raw material is prescribed so that there are no breaks in the cementing layer when the filter material 4 is agglutinated, and the required dimensions of the filtering area 4 and the flow contour in it are observed when pumping water for drainage of the excavation pit and cost efficiency requirements. Hydro-concrete, clay mud or clay may be used as the mortar 5. Mark the top layer of cement slurry

erected walls 7 structures in the manner "wall B. soil. After the required filtration strength has been obtained, the material of the cement slurry 5 is being dispersed; the filtration of the material 4 and the destruction of the mudcake in section 8 between the layer of filter material and the soil mass adjacent to the inner wall of the trench. Glutinization is carried out by feeding under the papora to the filter

material 4 through the tubes 3, - perforated in the zone of the filtering material, clean water mixed with compressed air and pumping out of the clay are null through the tubular wells 2 until full clarification of the il.py. After termination of the glaze, tube 3 is removed. Next, water from the filter material 4 is continuously pumped out through tubular wells 2 for the entire period of ground development between the walls of the structure, making the bottom and setting the bottom of the required strength. The mark of laying of the filter layer is assigned from the condition that
