Description

(54) METHOD OF CONSTRUCTION OF GROUNDS IN GROUND

The invention relates to the construction and can be used in the construction of underground structures in cna & ix. gravel soils.

There is a known method of erecting a structure in weak, water-saturated soils, including immersing a subsurface well with underwater excavation, laying the bottom of a drainage layer well, pumping out water, arranging concrete preparation, sticking waterproofing and laying structural concrete S bottom 1.

The disadvantages of this method are the difficulty of accurately submerging a well during underwater excavation and the need for subsequent pumping of water, which can lead to a loss of stability of the first well.

The closest to the invention to the technical essence of the achieved result is a method of erecting a structure in the ground, including the formation of wells with broadening at the ends over the entire area of the structure, creating walls in the soil along the permeable structure, and developing the soil between the steps. and device 2.

The disadvantage of the known method is that the adjacent one to the broadening arc does not form a continuous bottom, and therefore, when they are installed in weak to saturated soils, partial removal of the soil into the excavation is possible, in addition, to protect the structure from ascending, additional elevations below the bottom.

The aim of the invention is to reduce the filtration of panta water and increase the stability of the structure erected in water-saturated soils.

Claims (2)

The goal is achieved by the fact that according to the method of erection of a structure in the ground, including the formation of wells with wider ends over the entire area of the structure, the creation of walls in the ground along the perimeter of the erected structure, concreting the broadening of wells, the development of a single wall between the walls and the device The concentric rows, the heat cones, are made 3100 overlapping each other, and the upper surface is wider of each subsequent row and combined with the lower surface of the broadening of the previous row, counting from the walls Yeni. The bottom structure is carried out by concreting between the walls of the reinforced concrete slab and connecting it with a part of the crumbs to concreting the corresponding sections of the wells above the cicatrizes. Fig, I shows the built-in cooj, section; in fig. 2 - the bottom of the construction plan. Work on the proposed method is carried out as follows. From the day surface or from the pioneer trench, wells are formed with extensions t at the ends over the entire area of the structure and concreted well expansions. At the same time, the wells are formed in concentric rows, and their cherry blossoms 1 overlap each other, with the upper surface of the broadening of each successive row combined with the lower surface of the extensions of the previous row, counted from the walls 2 of the structure. Located at different levels of widening, they form a reverse dome. For the subsequent connection of the wells to the reinforced concrete slab of the bottom 3, part of the sections 4 of the well is reinforced to the mark of the reinforced concrete slab of the bottom 3. Then the walls 2 in the ground are created around the perimeter of the erected structure, for example, by means of a drop well. After the well is lowered onto the project mark, the reinforced concrete slab of bottom 3 is concrete-cast between its walls and embedded into it corresponding concreted sections of 4 wells above recesses 1. Technical and economical advantages of the proposed construction method are significantly reduced by the amount of basic works on the device bottoms; the installation of the inverse filter is not required, the reinforced concrete slab of the base is substantially lightened due to the introduction of part of the dome-shaped dome roof pile into it. In addition, the dome-shaped arch of drilling piles together with the ground above it serves as an additional load against the ascent of the structure, and its shape reduces the specific pressures acting from the ground. Invention 1. A method of erection of a structure in a foundation, including the formation of wells with extensions at the ends over the entire area of the structure, concreting the inflictions of wells, creating walls in the soil along the perimeter of the structure being constructed, developing the soil between the walls and making the bottom, characterized in that reduce the filtration of groundwater and increase the stability of structures erected in water-spread soils, the wells form in concentric rows, and their enhancements are performed overlying each other, and the upper surface uschireny each subsequent row sovmedayut with the lower surface of the broadening of the previous row counting from the wall structures. 2. A method according to claim 1, characterized in that the device of the bottom is carried out by concreting between walls / a reinforced concrete slab and connecting it with a portion of concretions by concreting the corresponding sections of the wells above these reinforcements.
