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 tunnel anti-deformation emergency support device, comprising: a support capsule, which is arranged in the tunnel; pressurization equipment, which is conductively connected to the capsule and presses a pressurized medium into the capsule until the support capsule is supported on The inner wall of the tunnel segment. The invention solves the problem of unbalanced bearing capacity due to tunnel deformation in a timely manner, and further ensures the orderly implementation of subsequent tunnel construction.

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 ...
