A method for slipping into place of a large-scale soil-covered bullet tank

Abstract

The invention provides a slide-to-position method for a large earth-covering bullet pot. The method comprises the following steps: S1, according to a planning design of a sand bed, calculating the fall between the elevation of a field installed and welded region and the elevation of the bullet pot in position on the sand bed, and designing the height, to which the bullet pot needs to be jacked; S2, performing a jacking operation: jacking the earth-covering bullet pot to the field installed and welded region to the designed height by using a jacking bracket; S3, sliding the bracket to position: after the earth-covering bullet pot is jacked to the designed height, transferring the bullet pot to a slide bracket on a slide rail, and jacking the slide bracket till the elevation of the bullet pot exceed the minimum passage height of the sand bed; S4, horizontally pushing and sliding: pushing the bullet pot to the corresponding designed position on the sand bed by using a pushing device; and S5, enabling earth-covering bullet pot to be in position: moving the slide bracket in the bottom of the bullet pot out, wherein the bullet pot fully falls to the corresponding position of the sand bed. The method provided by the invention can mount the large earth-covering bullet pot in position, and is relatively low in cost and high in using efficiency.

Description

technical field [0001] The invention belongs to the field of in-position installation of large-scale earth-covering tanks, in particular to a method for pushing and sliding in-position of large-scale earth-covering bullet tanks. Background technique [0002] The large earth-covering tank is a storage pressure vessel with a volume of generally 2000m 3 and above, the weight of a single container is about 700 tons. After the construction is completed, the earth-covering tank is placed on the sand bed 2-3m above the ground. The outside of the earth-covering tank is covered with dense sand, such as image 3 shown. Because the surface of the earth-covered tank is covered with sand, it is safer than the bare container, and the safety distance requirements for the surrounding buildings are relatively small. It is a container product that will be developed and promoted in the future. [0003] However, due to the large self-weight and structural size of the large earth-covering tan...

Problems solved by technology

[0003] However, due to the large weight and structural size of the large soil-covered tank, and the large size of the sand bed, it is difficult to use a traditional crane to lift and place it
