Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a TBM pipe segment water stop strip limiting clamping device. Background Art

[0002] During TBM (Tunnel Boring Machine) construction, in order to ensure the waterproof performance of the tunnel structure, it is necessary to paste and install waterstop strips in the waterstop strip installation grooves around each ring of TBM segments. As an important waterproof material, the installation quality and tightness of the waterstop strip are crucial to preventing groundwater infiltration.

[0003] However, due to the flexibility and elasticity of the water stop strip itself, it is easy to warp up during installation, especially at the corners. In addition, the adhesive cures slowly. After the warped water stop strip forms a gap with the TBM segment, the curing of the adhesive will lead to an insufficient connection between it and the TBM segment, forming a gap, which in turn affects the waterproof effect of the water stop strip. This will not only reduce the waterproof performance of the tunnel, but may also lead to water seepage problems in subsequent construction, increasing maintenance costs and safety hazards.

[0004] In addition, in order to ensure the installation connection strength between the waterstop strip and the TBM segment, the curing waiting time of the adhesive will be extended. While waiting for the adhesive to cure, the corner position may be damaged by collision due to exposure. When the waterstop strip at the corner is damaged, it will affect the waterproof performance of the tunnel in the later construction, resulting in a decline in project quality. Summary of the invention
