Embodiment Construction

[0015] In order to facilitate the understanding of the structure of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.

[0016] refer to figure 1 , is a schematic diagram of the overall structure of the tunnel anti-deformation emergency support device of the present invention. Such as figure 1 As shown, the present invention provides a tunnel anti-deformation emergency support device, comprising: a support capsule 1, which is arranged in the tunnel 2 to be auxiliary propped up; a pressurizing device 4, which is connected to the support capsule 1 and supports The capsule body 1 is pressed into the pressurized medium until the support capsule body 1 stably props up and down against the inner wall of the segment of the tunnel 2 .

[0017] More preferably, the outer surface of the expanded support capsule 1 is corrugated. The pressurized medium is gas or liquid, and the pressurized device 4 is a pressuriz...

Abstract

The invention provides a deformation-resistant emergency supporting device for a tunnel. The deformation-resistant emergency supporting device for the tunnel comprises a supporting bag and pressurizing equipment; the supporting bag is arranged in the tunnel; and the pressurizing equipment is connected with the bag in a communication manner, and presses pressurizing media into the bag until the supporting bag is abutted to a duct piece inner wall of the tunnel. By the deformation-resistant emergency supporting device for the tunnel, the problem that carrying capacity is balanced due to the fact that deformation of the tunnel is dealt with in time is solved, and orderly implementation of follow-up tunnel construction is guaranteed further.

Description

technical field [0001] The invention relates to a support device, in particular to an emergency support device applied in a tunnel environment to resist deformation. Background technique [0002] At present, in the shield tunneling project, the deformation of the surrounding soil layer or soil mass and the change of the stress field caused by the construction, as well as the extrusion, agitation, vibration of the construction machinery, etc., will cause damage to the existing subway tunnel structure. The unbalanced force will cause the tunnel structure to undergo local horizontal displacement, settlement, tension, compression and many other deformations. Once the above deformation exceeds the bearing capacity of the tunnel structure, it will inevitably make the tunnel deformation continue to develop, which will lead to the destruction of the tunnel structure. [0003] Therefore, it is very necessary to start researching and developing a technical solution that can deal with ...
