A full-soil-covered vertical tank structure

Abstract

The invention relates to a full-covered soil structure of a vertical tank, which is arranged outside the vertical tank and includes: a base layer, a slope fill and a buffer layer, the base layer is arranged around the vertical tank, Consisting of base material on the ground surface, a first filling gap is formed between the base layer and the outer wall of the vertical tank; the slope filling is arranged on the upper part of the base layer, and the A second filling gap is formed between the side of the slope filling near the vertical tank and the outer wall of the vertical tank, and the outer side of the slope filling forms a side slope; the buffer layer forms In the first filling gap and the second filling gap, buffer materials are filled in the first filling gap and the second filling gap to wrap the surface of the vertical tank body. The invention optimizes the soil-covering structure around the vertical tank body, enhances the integrity and stability of the entire soil-covering structure, and buffers the stress change between the tank body and the soil-covering structure.

Description

technical field [0001] The invention relates to the field of soil-covered tanks, in particular to a full-soil-covered vertical tank structure. Background technique [0002] Soil-covered storage refers to the pressurized storage of liquefied petroleum gas at room temperature in tanks or under the ground, and reasonable and comprehensive backfilling. This technology is very suitable for storage of flammable and explosive liquid materials, and can The tanks are protected to prevent the heat and shock waves of combustion and explosion from affecting other tanks, which can effectively reduce risks, and the tanks can be installed closer to each other, saving space. At present, the technology of full vertical tank body is not yet mature. Foreign countries mainly use half-layer soil covering technology, the bottom member of the tank body supports the structure, and the upper layer is covered with soil. The formed slope is larger, and the stress situation between the entire earth-co...

AI Technical Summary

Problems solved by technology

At present, the technology of full vertical tank body is not yet mature. Foreign countries mainly use half-layer soil covering technology. The bottom member of the tank body supports the structure and the upper layer is covered with soil. The formed slope is larger, and the stress situation between the entire earth-covering structure is more complicated, and the whole earth-covering structure needs to focus on its explosion-proof performance, and the poor integrity and stability of the earth-covering structure may not be reflected when the tank is static , but when the tank unexpectedly explodes, the unstable earth-covering structure will not be able to buffer the explosion, especially in the case of secondary or more complicated explosions, and the earth-covering structure will easily collapse

In addition, because the volume of the tank body in this field is generally large, the soil volume of the soil-covering structure is large, and the soil-covering structure formed has complex earth pressure changes inside. The existing technology does not have good measures to solve this practical problem, resulting in soil-covering The tank inside the structure is prone to damage, deflection and other problems. How to design to ensure the stability of the fully covered soil slope structure, avoid problems with the tank inside the fully covered soil slope, and at the same time avoid cracking and collapse of the fully covered soil slope structure itself , subsidence and other issues need to be resolved urgently
