 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.

(57) Abstract: The invention relates to the construction and can be used in the construction of tank farms for storage of liquid products. The base steel vertical tank includes a support element made in the form of an annular reinforced concrete grillage, and sand filling, the top of which is formed densified sand cushion. What's new is that on the circular piled raft Foundation supported the wall of the tank, and sand backfill is made trapezoidal trench filled with filler, which supported the bottom of the tank. The technical result of the invention is to create a basis for vertical steel tanks high capacity weak, startbanner soils. 2 C.p. f-crystals, 2 Il. The invention relates to the construction and can be used in the construction of tank farms for storage of liquid products. There is a construction base for vertical steel tanks [1], consisting of an annular reinforced concrete grillage on reinforced concrete piles, overlapping arranged from trapezoidal ribbed slabs. The drawbacks of such reasons are: snclavalin bearing capacity of Foundation under the wall and bottom. Known Foundation cylindrical tank [2], representing two rows of piles, submerged along the perimeter of the reservoir and the joint on top of the monolithic reinforced concrete raft. Tank diameter smaller than the inner diameter formed by the grillage. Thus, the reservoir has the ability to freely move within the grid. The disadvantage of this design is that it is not considered a significant pressure difference on the ground under the wall and under the bottom. Such a Foundation may not be used in the construction of reservoirs on the soft ground. Sludge tank on the high ground will exceed the permissible limits set by the SNiP. Closest to the proposed solution is the Foundation of the tank, comprising concentrically arranged annular supporting tape diamond-shaped cross section, rigidly connected to each other, the space between which is filled with compacted granular material [3]. It is known that the load under the tank wall is the weight of the walls, roof and snow loads and significantly exceeds the load from the tank floor. However, this solution bearing under the wall made in) has the possibility of precipitation. When the transmission load on compacted granular material "arch effect" occurs only until the middle of the diamond-shaped cross straps. All of the above leads to decrease in the reliability of the Foundation. The task, which is aimed by the invention is the construction of bases for vertical steel tanks high capacity weak, startbanner soils. The problem is solved due to the achievement of the technical result consists in increasing the bearing capacity of the Foundation. This technical result is achieved by the fact that at the base of the vertical steel tank containing the supporting element is made in the form of an annular pile grillage, and sand filling, the top of which is formed densified sand cushion, circular piled raft Foundation supported the wall of the tank, and sand backfill is made trapezoidal trench filled with filler, which supported the bottom of the tank. In addition, the trapezoidal trench performed prior to pile driving and filled with a sand-gravel mixture, and the trench, backfilling and compaction is made from borders to the middle of the Finance under the wall, loads which exceed the load under the bottom. Under the wall of the tank base is performed pile, and under the bottom - ground. Resulting in the precipitation tank does not exceed the allowable standards. Bearing capacity of pile Foundation and bearing capacity of sandy correspond to the loads, perceived from the wall and the bottom with the product. Thus, a fully used bearing capacity of the pile Foundation and the sand cushion that provides reliability reasons. The essence of the invention is illustrated by drawings, where Fig.1 shows a cross-section of the bottom of the tank of Fig.2 is a top view. The base steel vertical tank includes pile Foundation 1, circular reinforced concrete grillage 2, trapezoidal longitudinal and transverse trench 3 is filled with the filler 4, and sandy 5 and sand filling 6. For circular reinforced concrete grillage 2 supported by the tank wall 7. Foundation construction for steel vertical tank is as follows. Sand backfill 6 indentations are mutually perpendicular to the trench 3. And ustroystv 3 are filled with a filler 4, for example, a sand-gravel mixture, then driven piles 1 under the circular grating 2. After the device the annular pile cap 2 formed a bowl filled with sand and seal, forming a sandy 5. The proposed basis will allow you to build a vertical steel tanks of greater capacity on the weak, startbanner the soil as the ground under the tank wall is a reinforced concrete pile caps, and the pressure under the bottom of the stand most of the weak soils.
