Description

Technical Field

[0001] The utility model relates to the technical field of tunnel waterstops, in particular to an ethylene propylene diene monomer (EPDM) rubber waterstop for tunnels. Background Art

[0002] During the construction of a tunnel, in order to prevent water in the rock stratum from seeping into the tunnel, a waterstop needs to be poured at the expansion joint.

[0003] Currently, the internally pasted rubber waterstop in use is generally an OMEGA (Ω) waterstop. Because this type of waterstop can adapt to large three-dimensional displacements and has good sealing performance for the complex deformations of structures such as tunnels.

[0004] However, since an underwater tunnel needs to undergo repeated displacement changes during use, including lateral contraction, longitudinal shear, or multi-angle three-dimensional deformation, this requires the rubber waterstop to have multi-dimensional deformation ability in order to always maintain a seal with the concrete structure of the expansion joint. The existing rubber waterstops can generally achieve good lateral contraction. When encountering multi-angle displacement changes, leakage points are likely to form at the side contact positions of the remaining expansion joints, resulting in the sealing failure of the rubber waterstop and causing invisible damage to the building structure.

[0005] Therefore, how to design a waterstop for tunnels that can adapt to multi-angle displacement deformation and has good sealing performance is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0006] The utility model provides an EPDM rubber waterstop for tunnels to solve the technical problem that leakage points are likely to appear in the existing waterstop due to multi-angle displacement deformation.

[0007] The technical solution of the utility model to solve the above technical problem is as follows: an EPDM rubber waterstop for tunnels, comprising: a waterstop body, a plurality of anchor bodies, and a deformable body.

[0008] A cavity is provided inside the waterstop body, and the cavity is filled with a viscous waterproof material; the plurality of anchor bodies are fixedly spaced on the surface of the waterstop body; the deformable body is located between the plurality of anchor bodies and is fixed on the surface of the waterstop body.

[0009] The beneficial effect of the utility model is: by changing the structural design of the traditional waterstop, a cavity is provided inside the waterstop body. Since the cavity is filled with a viscous waterproof material, it can greatly improve the multi-angle deformation amount of the waterstop while improving the sealing effect of the waterstop (using the waterproof material to fill the leakage points that appear in the waterstop body) and protecting the safety of the tunnel.

[0010] On the basis of the above technical solution, the utility model can be further improved as follows.

[0011] Further, connection plates integrally extend from the upper part of one end and the lower part of the other end of the water stop belt body, and plug-in plates are fixed to the free end faces of the two connection plates. Plug-in grooves with the same cross-section as the plug-in plates are provided at the lower part of one end and the upper part of the other end of the water stop belt body; the two plug-in plates of two adjacent water stop belt bodies are respectively inserted into the two plug-in grooves.

[0012] The beneficial effects of the above further measures are as follows:

[0013] 1. The plug-in plates of two adjacent water stop belt bodies are adaptively inserted into the plug-in grooves, which can improve the connection efficiency and sealing effect of the water stop belt body;

[0014] 2. The plug-in plates and plug-in grooves at the upper part of one end of the water stop belt body are arranged in a staggered manner, which can stagger the water stop and avoid water seepage points between two adjacent water stop belt bodies.

[0015] Further, a deformation hole is provided in the middle of the deformable body.

[0016] Further, the waterproof material is a non-solidifying mucus.

[0017] Further, the water stop belt body is made of ethylene propylene diene monomer (EPDM) material.

[0018] Further, the cross-section of the anchor body is a T-shaped structure. BRIEF DESCRIPTION OF THE DRAWINGS
