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 ...
