Description

Technical Field

[0001] The utility model belongs to the technical field of embedded water stop strips, and particularly relates to an embedded water stop strip for hexagonal tunnel segments. Background Technique

[0002] The water stop strip of tunnel segments is an important water stop structure for preventing groundwater from entering tunnels or underground wells. Because of its good compressive resistance, tensile resistance and corrosion resistance, it is widely used in underground projects.

[0003] At present, the water stop strip of segments is innovatively pre-installed inside the segment steel formwork and embedded by pouring concrete. However, this way of embedding the water stop strip has the limitation of too small embedding area, resulting in insufficient anchoring force between the embedded water stop strip and the segment concrete body. There is a phenomenon that the embedded water stop strip falls off or is damaged during the later use of the segments. Due to the fixity of its embedded position and space limitation, it is very difficult to re-embed or repair, increasing the difficulty of waterproofing of tunnel projects and the risk of water leakage. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that at present, the water stop strip of segments is innovatively pre-installed inside the segment steel formwork and embedded by pouring concrete. However, this way of embedding the water stop strip has the limitation of too small embedding area, resulting in insufficient anchoring force between the embedded water stop strip and the segment concrete body. There is a phenomenon that the embedded water stop strip falls off or is damaged during the later use of the segments. Due to the fixity of its embedded position and space limitation, it is very difficult to re-embed or repair, increasing the difficulty of waterproofing of tunnel projects and the risk of water leakage, and to provide an embedded water stop strip for hexagonal tunnel segments.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an embedded water stop strip for hexagonal tunnel segments, including a plurality of water stop strip bodies. A plurality of installation grooves are arranged inside the hexagonal segment steel formwork, and the plurality of water stop strip bodies are correspondingly installed in the installation grooves. A plurality of anti-detachment parts are arranged on the water stop strip bodies.

[0006] As a further description of the above technical scheme:

[0007] The plurality of installation grooves are arranged up and down on the inner wall of the hexagonal segment steel formwork.

[0008] As a further description of the above technical scheme:

[0010] As a further description of the above technical scheme:

[0011] A clamping groove is arranged in the installation groove, a connecting angle is arranged on the water stop strip body, and the connecting angle is clamped in the clamping groove.

[0012] As a further description of the above technical solution:

[0013] A plurality of connecting tails are arranged on the water stop strip body facing the inside of the hexagonal segment steel mold, and the anti-detachment member is located between the plurality of connecting tails.

[0014] As a further description of the above technical solution:

[0015] The anti-detachment member is in a cross shape, a trapezoid with a wide outer part and a narrow inner part, or a gear shape.
