Oil tank reinforced earth protective body and construction method thereof

Abstract

The invention discloses an oil tank reinforced earth protective body and a construction method of the oil tank reinforced earth protective body. The oil tank reinforced earth protective body comprises a foundation and a main reinforced earth protective body. The main reinforced earth protective body is formed by alternately press-fitting geogrid layers and packing layers. One-way geogrids are arranged around an oil tank. The one-way geogrid on the lower layer is connected with the one-way geogrid on the upper layer in a tensioning mode through a connecting bar. Earth bags are stacked on the inner side of the one-way geogrid on the lower layer for compaction and press the one-way geogrid on the upper layer. Turf is wrapped on the sides, facing the outer portion of a wall, of earth bags on the outer side of the main reinforced earth protective body. One or two layers of two-way geogrids are arranged on the top of the oil tank. The two-way geogrids are filled with packing in a layered mode. Turf or grass seeds overspread the two-way geogrid on the uppermost layer. According to the oil tank reinforced earth protective body, by the adoption of a flexible geogrid reinforced structure, the problems that land is occupied and earthing can not be conducted during excavation and transportation of large-sized earth rock through a traditional buried oil tank are solved, and meanwhile the oil tank reinforced earth protective body has the advantages of being environmentally friendly, hidden, disguised, not prone to exposure, low in construction cost and the like.

Description

technical field [0001] The invention relates to an oil tank soil protection body, in particular to an oil tank reinforced soil protection body and a construction method thereof. Background technique [0002] Oil storage in soil-covered oil tanks is one of the important ways of strategic reserves of oil fronts in various countries in the world today. The construction procedure of the soil-covered oil tank is usually to excavate a certain space on the flat ground or hillside, build the oil tank, and then build the tank wall, pour the vault of the body, and assemble the tank accessories. Finally, cover with soil. [0003] The covering soil construction in my country requires that the thickness of the covering soil on the vault of the tank room should not be less than 0.5m, the width of the covering soil on the upper part of the wall is generally not less than 1.5m, and the covering soil slope should not be less than 1:1.5. Traditionally, earth is piled up directly around ...

AI Technical Summary

Problems solved by technology

Traditionally, earth is piled up directly around the oil tank, and the capacity of the earth-covered oil tank is generally 1000-10000m 3 , the volume is huge, and it is difficult to continue to cover the soil after reaching a certain height, and it is impossible to use mechanical tamping, and the structure is unstable

This method of covering soil has problems such as large land occupation, large amount of earthwork, and failure to cover the soil. It is difficult to meet the requirements of the covering soil standard, and rainwater is easy to wash away the covering soil. It requires a lot of maintenance costs every year, which is time-consuming and laborious.
