 Reservoir foundation / 2247193
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.
 Reservoir construction method / 2264504
Method involves preparing building site and ground base; mounting reservoir and performing hydraulic tests thereof. Reservoir mounting is performed in several stages. At the first stage reservoir is built without stationary metal bottom, has projected edges and is provided with temporary flexible bottom air-tightly pressed against projected edges with the use of pneumatic system. After that preliminary hydraulic tests are performed by filling reservoir with water. At the second stage temporary flexible bottom is demounted after complete ground base compaction, deformed ground base is smoothed up to reaching design mark by filling the formed cavity with filling material. Then waterproofing material is applied to smoothed base, permanent metal bottom is formed and the ready vessel is subjected to final hydraulic tests.
 Hazardous product storage reservoir foundation / 2270296
Foundation comprises earth-fill pad, water-tight layer arranged below the pad, drainage system consisted of a number of pipelines arranged in earth-fill pad body. Trench filled with interchangeable filtering material is dug out along foundation perimeter. Watertight layer is inclined under the earth-fill pad and has upper end of hollow square shape so that the hollow square is inclined towards straight channel adapted to accumulate rain water and located in lower pad part. The straight channel is communicated with drainage vessel. Well with controlled gate is formed in front of the drainage vessel. Drainage system pipelines are formed of perforated pipelines communicated one with another and arranged along a circle and inside it.
 Foundation for reservoir to be built in seismic zone / 2276710
Foundation includes mattress panel, which connects vertical and inclined piles. Vertical piles are uniformly distributed along large circle at mattress edge and along minor circle defined by mattress center. Inclined piles are grouped in pairs and arranged in vertical plane one above another. Each pair of inclined piles extending from mattress edge is connected with each vertical pile of minor circle in lower part thereof. Each pair of inclined piles extending from mattress center is connected with vertical pile of large circle in lower part thereof.
 Reservoir foundation / 2291251
Reservoir foundation comprises bearing panel laid on ground bed. The bearing panel has flat annular conical part having thickness increasing towards panel center and central conical part. Spring means are arranged between the annular conical part and central one. Spring means touch reinforced concrete ring. Central conical part is made as a cone facing upwards and composed of several members pivotally connected with each other in tops thereof and resting upon reinforced concrete ring. The members are connected with each other by flexible inserts.

The invention relates to the construction and can be used in the construction of reservoirs on strata heavily compressible soils. The method of construction of the basement reservoir device includes a dirt pillows, bored piles, United annular grillage, the implementation of testing and correcting the roll of the tank. What's new is that previously the ring through the cushion dipped driven piles, are well for bored piles and filled with concrete, leaving the upper part of the blank, then install reinforcing cages and pipe sleeves that secure with a valve grillage over wells, concreted ring grillage, uniting all piles, install the tank with access to wells after hydraulic testing and correcting the roll of the tank through the pipe-liner serves the concrete to fill the upper part of the wells and the involvement of piles. The technical result is to reduce sediment and rolls the tank. 2 Il.
The invention relates to the construction and can be used in the construction of reservoirs on strata heavily compressible soils.
The known method with the and the Foundation soil is removed to a thickness of the base plate and the height of the proposed underneath the heads of the piles, then at the bottom of the pit satisfied with sandy and install formwork for concreting of the slab.
The closest technical solution is the method of construction of pile Foundation of the tank (see Ivanov Y. K. and other Bases and foundations of the tanks. M., S. I., 1989, S. 53).
The disadvantages of the known methods of construction of foundations tanks are: the impossibility of accounting work annular grillage (on its load carrying capacity on the ground) and the complexity of the security requirements of small sediments and small allowable rolls during operation of the tanks.
The present invention is the provision of opportunities for accounting work annular grillage and software requirements of small sediments and small allowable rolls during operation of the tanks.
This object is achieved in that in the method of construction of the Foundation of the tank, including the device ground pillows, bored piles, United annular grillage, the implementation of hydro-testing and alignment of the roll of the tank, through the pre-dipped cushion driven piles, limiting lateral movement of the soil, are well for bored piles and filled with concrete, leaving imasu valve grillage over the wells, concreted ring grillage, uniting all piles, install the tank with access to wells and, after hydrotest and correct roll of the tank through the pipe-liner serves the concrete to fill the upper part of the wells and the involvement of piles.
The technical result of the invention is to reduce sediment and rolls the tank.
The novelty of the claimed proposal due to the fact that the inclusion of the work of bored piles after hydrotest and correct roll allows for virtually complete absence of sediment under operational loads.
The invention is illustrated by drawings, where Fig.1 shows a cross section of the Foundation of the tank (side view), and Fig.2 is a plan (top view).
The method of construction of the Foundation is carried out as follows. Tear off the pit and layers with compaction laid the ground cushion. The ring is dipped driven piles, limiting lateral movement of soil, drilling of wells and fill them with sealing concrete, not bringing it to the top level. Then install the reinforcement cage of the grillage. Over the wells set of short metal pipe sleeves, the bottom of which does not reach the vertical steel tank so to force it passed over the wells drilled piles, leaving access to them. Conduct the pressure test of the tank, controlling and locking precipitation. The load on the basis of the transfer of driven pile and loop pile Foundation. After unloading tank straighten roll, concreted left blank part of bored piles, feeding concrete pump concrete in sleeves.
During operation, the number of driven piles plays the role of ring-fencing preventing lateral movements of the soil, and bored piles, working in conjunction with caps and scoring, significantly reducing precipitation and rolls the tank.
The construction of the Foundation is carried out in the following sequence: off pit 1, stack with dirt seal cushion 2, the ring score of 3 piles, drilled wells 4, for bored piles installed reinforcing cages and fill with concrete wells 4 to the level of the gap 5, allowing a draught of grillage 6, install metal pipe-sleeve 7 over 4 wells, placing them so that they remain accessible for filling with concrete, concreted ring Foundation grillage 6.
After the pressure test of the tank, precipitation of ring Foundation grillage-6 and enable niteline will ensure the bearing capacity of the Foundation, preventing precipitation during operation.
Claims The method of construction of the Foundation of the tank, including the device ground pillows, bored piles, United annular grillage, the implementation of testing and correcting the roll of the tank, characterized in that the ring through the cushion dipped driven piles, are well for bored piles and filled with concrete, leaving the upper part of the blank, then install reinforcing cages and pipe sleeves that secure with a valve grillage over wells, concreted ring grillage, uniting all piles, install the tank with access to wells after hydraulic testing and correcting the roll of the tank through the pipe-liner serves the concrete to fill the upper part of the wells and the involvement of piles.
