Embodiment 1

[0033] Such as Figure 10 As shown, a high-toughness caulking waterstop for channel structures described in this embodiment includes a hard permeable pipe 9, the hard permeable pipe is a hollow pipe, and the outer wall of the hard permeable pipe 9 is sequentially provided with filter paper 8 And spray quick-setting rubber 6. During the transportation of this product, a layer of waterproof packaging film can be installed on the outside. The waterproof packaging film is a kind of packaging paper lined with high-density polyethylene film coating, which has good waterproofness and toughness, and plays the role of moisture-proof . The top of the hard permeable pipe 9 is provided with a rubber block 12, which is easy to open when overhauling and injecting water to the inside. The spraying quick-setting rubber is a two-component spraying quick-setting rubber material, which forms a dense, uniform, high-elasticity and high-toughness rubber with an average thickness of 2mm to 5mm wit...

Embodiment 2

[0045] Such as figure 2 As shown, the cross-section of a high-toughness caulking waterstop for channel structures described in this embodiment is composed of a ring and two semicircles intersecting, the two semicircles are located on both sides of the ring, and the rest Structure and construction method are the same as embodiment 1.

Embodiment 3

[0047] Such as image 3 As shown, the cross-section of a high-toughness caulking waterstop for channel structures described in this embodiment is a rectangular ring, and the rest of the structure and construction method are the same as in Embodiment 1.

Abstract

The invention relates to a high-tenacity caulking water stop belt for a channel structure. The high-tenacity caulking water stop belt comprises a hard water permeating pipe which is a hollow pipe. Bonding of filter paper and spraying of rapid hardening rubber are sequentially conducted on the outer wall of the hard water permeating pipe from interior to exterior, and a rubber block is arranged at the top end of the hard water permeating pipe. The manufacturing cost of the high-tenacity caulking water stop belt is not high, and materials can be conveniently taken from the local; a water stop structure formed by caulking filling materials can well adapt to deformation of an expansion joint, a composite material is formed by combining inorganic materials and organic materials, two main anti-seepage substances jointly play a caulking water stop role, wherein the inorganic materials are more durable and have larger deforming capability, and when the organic materials are in good condition, the inorganic materials play a filling and assisting role; and after part of the organic materials are out of action, the inorganic materials can continue to play a long-time, comprehensive and effective water stop role, and defects caused by the failure of the organic materials are completely offset.

Description

technical field [0001] The invention relates to a caulking waterstop, in particular to a high-toughness caulking waterstop for channel structures and a construction method thereof. Background technique [0002] In the construction of concrete lining joints, it is generally used to fill the expansion joints with caulking boards, and the surface of the joints is filled with polyvinyl chloride cement to achieve the purpose of forming expansion joints and sealing water, and rubber waterstops are also used to fill expansion joints. In the center of the seam, closed-cell foam boards are sandwiched outside to form seams and stop water. Vinyl chloride cement and rubber waterstops are polymer synthetic materials. After long-term operation, they will gradually age, harden and muddy under the erosion of the natural environment. Over time, these materials may lose their original elasticity and caulking. Reduced water stop effect. Contents of the invention [0003] The purpose of the...
