Embodiment 1

[0018] The foundation of a low-pressure vaulted steel storage tank adopts a ring-wall-type extension foundation, which is a reinforced concrete structure. Three-layer reinforced body, the filler layer is coarse sand, the inner expansion width of the ring wall type extended foundation is 0.8 meters, the lap length of the reinforced body is 0.8 m, and the height of the ring wall type extended foundation is 1.0 m. The material of the reinforced body is conventional geotextile, and each layer of reinforced body needs to be overlapped with each other to form a continuous and complete layer of reinforced body, but there is no overall reinforced concrete raft at the bottom.

[0019] The storage tank foundation can achieve the technical and economic rationality of the low-pressure storage tank foundation design scheme.

Embodiment 2

[0021] The foundation of a low-pressure vaulted steel storage tank adopts a ring-wall-type extension foundation, which is a reinforced concrete structure. One layer of reinforced body, the filling layer is stone chips, the inner expansion width of the ring wall type expansion foundation is 1.2 meters, the lap length of the reinforcement body is 1.2 meters, and the height of the ring wall type expansion foundation is 1.4 meters. The material of the reinforced body is conventional geogrid, and each layer of reinforced body needs to be overlapped with each other to form a continuous and complete layer of reinforced body, but there is no overall reinforced concrete raft at the bottom.

[0022] The storage tank foundation can achieve the technical and economic rationality of the low-pressure storage tank foundation design scheme.

Abstract

The invention relates to a low-pressure vault steel storage tank foundation, and mainly solves the problem that the economy is poorer due to the fact that a whole reinforced concrete raft and ring wall foundation form is adopted when the diameter of a low-pressure storage tank is continuously extended in the prior art. The adopted low-pressure vault steel storage tank foundation mainly comprises ring wall type extended foundations, a filler layer and reinforcement bodies, wherein the ring wall type extended foundations are located at the lower part of the storage tank, the filler layer is located between a bottom plate at the lower part of the storage tank and the ring wall type extended foundations, and at least one layer of reinforcement bodies is arranged in the filler layer. By means of the technical scheme of the low-pressure vault steel storage tank foundation, the problem is better solved.

Description

technical field [0001] The invention relates to a foundation of a low-pressure vaulted steel storage tank. technical background [0002] The design pressure of the low-pressure storage tank is different from that of the atmospheric pressure storage tank. Since there is an internal pressure greater than the normal pressure in the tank and the pressure is a one-dimensional scalar quantity, the internal pressure not only acts on the tank vault and tank wall, but also acts on the tank bottom . The downward internal pressure acting on the horizontal bottom plate of the tank will be directly transmitted to the plate through the tank bottom plate because the tank bottom plate is a very thin (relative to the tank wall) film-shaped member and is connected orthogonally to the vertical tank wall. The underlying filler layer and the underlying overall reinforced concrete raft foundation. The upward pressure acting on the vault will generate an upward lifting force on the tank wall. T...
