Reservoir foundation

FIELD: building, particularly foundations for large reservoirs and similar structures.

SUBSTANCE: foundation includes ring-shaped foundation member located under reservoir walls and base formed as a row of piles driven in ground and connected by ring-shaped end cross having cuts. Reservoir bottom center includes plate with levers located in ring-shaped end cross cuts and connected to ring-shaped foundation member by rods.

EFFECT: reduced reservoir immersion in ground due to elimination of horizontal ground slide and restriction of reservoir bottom center flexure.

The invention relates to the construction and can be used in the construction of foundations and preparation of foundations for large tanks and similar structures.

Known for the Foundation of the tank to reduce lateral movements of the soil are "ring ring" from immersed in a checkerboard pattern of two rows of piles, the combined ring grillage, over which is laid a sand cushion. [Ivanov J.K. and other Bases and foundations tanks, Meters, S.I. 1989, ñ.38, 43, 49].

Known for the Foundation of a cylindrical tank in the form located in the ground of the cylindrical element, inner diameter which exceeds the outer size of the tank, where to reduce the consumption of materials during construction on weak Foundation soils cylindrical element made in the form placed at a distance from each other piles, merged on top of the annular pile cap, mark the top of which is below the vessel wall by a value not less than 1.2 projected rainfall ground, and the depth of burial piles is 0.6 - 0.7 height of the vessel wall (AS the USSR № 887737, E 02 D 27/38).

The disadvantage of this Foundation is that it is impossible to completely eliminate the extrusion weak soil between the piles, which will lead to uneven settlement under the bottom of the tank, the AK how is the deflection under the center.

Known for the Foundation of the tank, which is the closest analogue, which includes located near the walls of the tank ring Foundation, and the Foundation in the form of a series of driven piles (see Ivanov J.K. and other Bases and foundations tanks, Meters, stroiizdat, 1989, S. 99-107).

The objective of the invention is to reduce the sludge tank by reducing the horizontal displacements of the soil and limit the deflection of the center of the bottom.

The problem is solved due to the fact that the Foundation of the tank includes located near the walls of the tank ring the basis and Foundation in the form of a series of driven piles, according to the invention, piles United annular pile cap is made with cutouts, and the center of the bottom of the tank has a plate with the control levers located in the notches of the annular pile cap and connected with the annular Foundation through the bars.

Through collaboration plate, reinforcing the bottom of the tank, and levers connected with the circular Foundation of the tank, is compensated by the difference in the settling tank floor.

The invention is illustrated by drawings, where figure 1 - cross section of the Foundation and the bottom of the tank (side view), figure 2 is a plan (top view).

The Foundation of the tank 1 includes a number of piles 2, United annular pile cap 3 with openings 4 for the passage of the levers 5, United with the plate , reinforcing the center of the tank, and by means of rods 7 with a circular Foundation 8 the tank itself.

The Foundation built in the following sequence: tear off the pit (depth of excavation of order 0,3D tank should exceed the depth of the sole Foundation), arrange ground cushion, hammer ring, the number of piles 2, combine piles annular pile cap 3, which arrange the cutouts 4, they are placed levers 5 are connected with the plate 6 to reinforce the bottom of the tank, and through the rods 7 with a circular Foundation of the tank. Then on the surface of the compacted cushion erect a ring Foundation 8 under the walls of the tank 1.

The Foundation of the tank, including located near the walls of the tank ring Foundation, and the Foundation in the form of a series of driven piles, characterized in that the piles United annular pile cap is made with cutouts, and the center of the bottom of the tank has a plate with the control levers located in the notches of the annular pile cap and connected with the annular Foundation through the bars.
