Abstract

The invention provides a gas film base structure applied to plateau frozen earth and a construction method of the gas film base structure. The gas film base structure includes a gas film body and a gas film base, a gas film cavity is formed by enclosing between the gas film body and the ground, the gas film body is mounted on the gas film base, and the gas film base comprises a base body and a tooth structure, wherein at least part of the base body is buried under the ground; the tooth structure is arranged on the side elevation surface of the base body and used for improving the pull-out resistance between the gas film base and a ground layer. According to the gas film base structure applied to plateau frozen earth and the construction method of the gas film base structure, the problems that the gas film structure in the prior art cannot give consideration to both frozen earth layer protection and pull-up force satisfaction is solved.

Description

technical field [0001] The invention relates to the technical field of air-film construction equipment, in particular to an air-film foundation structure suitable for plateau permafrost and a construction method thereof. Background technique [0002] The air-film building is an air-supported building. The entire air-film building exerts no downward pressure on the foundation, but an uplift force. The common air-film foundation is in the form of reinforced concrete, and its foundation is about 1.0 to 1.5 meters buried in the ground. Underground, about 0.3 to 0.6 meters above the ground, can meet the uplift force and horizontal force of the air film building. However, the permafrost layer in the plateau area is relatively shallow. When the foundation is buried, the permafrost layer is easily damaged if it is buried too deep. [0003] That is to say, the air film structure in the prior art has the problem that the protection of the permafrost layer and the satisfaction of the ...
