Outer protecting type copper water stop structure and outer protecting method thereof

Abstract

The invention relates to an outer protecting type copper water stop structure and an outer protecting method thereof. The outer protecting type copper water stop structure comprises a water stop copper piece which is integrally formed by two copper piece bodies, and a wrapping body wrapping the outer side of the water stop copper piece. The outer protecting method includes the steps that the interior of the water stop copper piece is filled with and closed by foam materials; the wrapping body closely wraps the water stop copper piece; and after the outer protecting type copper water stop structure strides over a seam to be in place, concrete components on the two sides are poured successively, and a reserved telescopic seam is formed between the concrete components on the two sides. According to the outer protecting type copper water stop structure and the outer protecting method of the outer protecting type copper water stop structure, due to the fact that the wrapping body is arranged on the outer side of the water stop copper piece, a space in which the water stop copper piece can conveniently stretch and deform is formed in the outer side of the water stop copper piece, the deformation restraint of the water stop copper piece can be remarkably reduced, the water stop copper piece can fully stretch and deform according to the expectation of a designing party when the expanding, settling and / or shearing three-direction position change happens to the telescopic seam, and the water stop reliability of the copper water stop structure is remarkably improved.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to an external protection type copper water-stop structure and an external protection method thereof. Background technique [0002] Concrete members of hydraulic structures such as dams, water channels, water tunnels and aqueducts are usually provided with expansion joints. In order to prevent these expansion joints from leaking, copper stoppers are usually embedded across the joints when pouring concrete. Water or rubber waterstop. [0003] Taking copper water stop as an example, it is usually made of copper sheet with a thickness of about 1 mm and strong deformation ability. The copper sheets of the two wings are poured into concrete, and nose-shaped protrusions are reserved at the joints as the deformation parts of the copper sheets to absorb the deformation of expansion joints. During the operation of hydraulic structures, when there is temperature stress or founda...

AI Technical Summary

Problems solved by technology

The tight wrapping effect of the concrete causes the resistance of the copper water-stop nose to be too large when it deforms with the joint deformation. The deformation ability of the copper nose has not been fully exerted, and the possibility of the root of the copper nose being pulled off is greatly reduced. Waterproof reliability of copper waterstop

When designing copper waterstop structures, engineering designers usually estimate the possible maximum opening, settlement or shear displacement of expansion joints, and then design the height and width of copper waterstop noses that match the deformation. The tight wrapping effect of the copper nose
