Sliding type air bag plug plate system for tunnel lining trolley

Abstract

The invention relates to a sliding type air bag plug plate system for a tunnel lining trolley. The sliding type air bag plug plate system for the tunnel lining trolley comprises a trolley template first lug plate, a trolley template second lug plate, a plug plate base, a sliding square pipe shaft, a pressing plate assembly, a lower sliding plate, an upper sliding plate, a lifting adjusting mechanism, a bolt assembly and an air bag, wherein the lower sliding plate and the upper sliding plate are arranged on the sliding square pipe shaft, the lifting adjusting mechanism is used for adjusting the lower sliding plate and the upper sliding plate to slide up and down on the sliding square pipe shaft, and the air bag filled with air is pushed by upward sliding of the upper sliding plate to be attached to the tunnel excavation lining face. The sliding type air bag plug plate system for the tunnel lining trolley is ingenious in design and convenient to construct, the technical difficulty for operators is lowered, the labor intensity of the operators is relieved, the installation efficiency and quality of a water stop belt are improved, and the technical problems that the installation quality of the tunnel secondary lining water stop belt is poor, and a plug plate is difficult to seal and fit due to the fact that the excavation face is irregular through a drilling and blasting method are solved; for the prior art, good market prospects and development space are realized.

Description

technical field [0001] The invention relates to the field of a plug plate system for a tunnel lining trolley, in particular to a sliding airbag plug plate system for a tunnel lining trolley. Background technique [0002] Tunnel lining is an essential process to support and maintain the stability of tunnel structure, and the quality of tunnel lining plays an important role in maintaining the safety of train operation. Due to the particularity of underground tunnels, tunnel water leakage will not only reduce the durability of the concrete lining, but also reduce the functions of various facilities in the tunnel and deteriorate the operating environment in the tunnel. Therefore, the installation of the waterproof board of the waterstop is directly related to the safety issue. [0003] In the construction of tunnel engineering, due to the long mileage, it is often impossible to complete the pouring at one time, or due to the deformation of the foundation, or the thermal expansi...
