Problems solved by technology

[0003] In the existing construction technology, the traditional storage tank inversion technology is often used, that is, the method of inverting the outer tank first, then the inner tank is constructed one by one, and finally the inner tank is constructed with a flat ceiling. The construction is difficult and the construction efficiency is high. Low, long construction period, greater impact on project progress, and at the same time, there are great difficulties in transporting inner tank materials into the tank

Embodiment Construction

[0031] Below in conjunction with accompanying drawing, by describing embodiment, the present invention will be further described:

[0032] Such as figure 1 , 2 , 3, a kind of inner tank roof of the present invention is a double-layer storage tank construction method with a flat ceiling, including the construction of the inner and outer tank bottom plates, the inner tank flat ceiling, the construction of the outer tank vault roof plates 3, 4, and the inner and outer tanks. The construction of tank wall panels 5 and 6 includes the following steps:

[0033] 1), blanking, prefabricating inner and outer tank bottom plates, inner and outer tank wall panels 5, 6, inner tank flat ceiling 3, outer tank vault roof plate 4 and parts.

[0034] 2) Assemble the bottom plate of the outer tank.

[0035] 3) After the bottom plate of the outer tank is assembled, the flat ceiling 3 of the inner tank is prefabricated on the bottom plate of the outer tank, and then the belts 1 to 2 of the outer...

Abstract

The invention discloses a construction method for a double layer storage tank with a flat suspended ceiling as an inner tank roof. The method comprises following steps: installation of an inner tank top ring wallboard, a flat suspended ceiling and an outer tank dome; simultaneously upside down lifting of the inner tank flat suspended ceiling, inner tank top ring wallboard and the outer tank dome; after the installation of the inner tank wallboard is finished, the outer tank wallboard is inversely mounted in order; after the construction of a thermal insulation layer between the inner tank base plate and the outer tank base plate is finished, an inner tank base plate is paved. By means of the construction method, the construction efficiency is effectively increased, the construction period is shortened, the difficulty for dumping and transferring the material in the inner tank is reduced, and construction cost is reduced.

Description

technical field [0001] The invention relates to an installation technology of a double-layer storage tank, in particular to a construction method of a double-layer storage tank whose inner tank roof is a flat suspended roof. Background technique [0002] Double-layer storage tanks are widely used in the storage of cryogenic liquids such as liquid oxygen, liquid nitrogen, liquefied petroleum gas and ethylene. The general design structure of large cryogenic double-layer storage tanks is a flat ceiling structure, the outer tank is a vault structure, the inner tank is a flat roof structure, and the flat roof of the inner tank is hung on the outer tank vault with a boom; the construction technology requirements are high, and the construction High difficulty. [0003] In the existing construction technology, the traditional storage tank inversion technology is often used, that is, the method of inverting the outer tank first, then the inner tank is constructed one by one, and fin...
