Problems solved by technology

[0004] (1) At present, the settlement joints of underground structures mostly adopt waterproof measures such as mid-buried waterstops, which have poor deformation ability and are easy to separate from the concrete or crack when the deformation is large
[0005] (2) The traditional tunnel waterproof system cannot adapt to the ultra-long segmented structures that have generally appeared in recent years
[0006] (3) The current water-stop material used is poor in replaceability

Abstract

The invention discloses a two-way sliding extrusion type large deformation waterproof deformation seam structure, which comprises a sliding extrusion box, an extrusion elastic material and a sliding bolt. The sliding extrusion box includes an extrusion part and a container part. The extrusion The pressure part and the container part are made of rigid materials, the top of the container part is open, the extrusion part is located on the top of the container part and the inside of the container part is divided into two spaces, and extruded elastic materials are placed in each space, and the extrusion part It is connected with the container part through a sliding bolt; the sliding bolt can limit the container part and squeeze it out.

Description

technical field [0001] The invention relates to the technical field of tunnels, and is especially suitable for the technical field of design and construction of tunnels. Background technique [0002] During the operation of the tunnel, due to the influence of groundwater, water seepage and water leakage at the deformation joints of the tunnel are very common. At present, lengthening the segmental length of the tunnel and increasing the spacing of deformation joints are one of the effective control methods. However, with the increase of the spacing of deformation joints, the waterproof ability of the deformation joints is often not effectively guaranteed. [0003] At present, the waterproof measures widely used in tunnel deformation joints mainly have the following problems: [0004] (1) At present, waterproof measures such as mid-buried waterstops are mostly used for the settlement joints of underground structures, which have poor deformation ability and are easy to separat...
