TECHNICAL FIELD

[0001] The utility model relates to the technical field of curtain cloth, concretely to a splicable hole rubber waterstop curtain cloth. BACKGROUND

[0002] The hole rubber waterstop curtain cloth, as a key waterstop component in modern tunnel, subway and water conservancy engineering and other underground construction projects, plays a vital role, and in the complex and changeable underground construction environment, ensures the effective waterstop at the hole, has inestimable value for guaranteeing engineering quality, construction progress and subsequent operation safety.

[0003] The existing waterstop curtain cloth is mostly composed of thickening area, sealing area and sealing protruding ring and the like, and in the actual application process, the bolt hole is arranged at the thickening layer, and is often in contact with the turning plate, which will cause great wear at the thickening layer, and when the thickening area is damaged and needs to be replaced, the whole curtain cloth is often replaced, which will cause the waste of the curtain cloth material in the intact area and unnecessary loss. UTILITY MODEL CONTENT

[0004] The utility model discloses a splicable hole rubber waterstop curtain cloth, which aims at solving the problems in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a splicable hole rubber waterstop curtain cloth, comprising a first curtain cloth, a plurality of first bolt holes are arranged on the first curtain cloth in a ring array, rubber protrusions are symmetrically arranged on both sides of the first curtain cloth, a sealing ring is fixedly connected to the inner side of the first curtain cloth, a second curtain cloth is movably sleeved on the first curtain cloth, a plurality of second bolt holes are arranged on the second curtain cloth in a ring array, and guide grooves are arranged on the second curtain cloth corresponding to the rubber protrusions.

[0006] Preferably, the first bolt hole and the second bolt hole are correspondingly arranged, and the first bolt hole and the second bolt hole have the same diameter.

[0007] Preferably, the rubber protrusion is designed in a rectangular structure, and the material of the rubber protrusion is the same as that of the first curtain cloth.

[0008] Preferably, the first curtain cloth and the second curtain cloth are designed in a ring structure, and the cross section of the second curtain cloth is designed in a tilted concave structure.

[0009] Preferably, the rubber protrusion and the guide groove are slidably connected.

[0010] Compared with the prior art, the utility model discloses the beneficial effect is: the sealing area and the thickening area of water stop curtain cloth are split into first curtain cloth and second curtain cloth, can make first curtain cloth and second curtain cloth free dismount simultaneously, when second curtain cloth produces greater wear and needs to change, only needs to split second curtain cloth and changes, avoids the curtain cloth maintenance in actual use, produces the situation of material waste.
