Problems solved by technology

[0002] In existing concrete structures, such as retaining dams, reservoirs, subways, culverts, sluices, tunnels and other underground projects, due to the inability to pour continuously or the deformation of the foundation settlement (earthquake), or the concrete caused by temperature changes Due to thermal expansion and contraction of components, deformation joints and construction joints are often left during pouring. These gaps must take anti-leakage measures to prevent external water or groundwater from leaking into the structural space. Concrete grooves are set between the concrete and the second-stage concrete, and soft asphalt and copper sheets or rubber waterstops are installed in the grooves. However, this method requires prefabricated concrete grooves. The outer 3 sides are chiseled, which will prolong the construction period and increase labor. At the same time, because the length (height) of each concrete groove is generally only 50-100cm, the expansion gap must be composed of multiple concrete grooves, so multiple horizontal lines will be generated. The cracks and the irregular deformation of multiple concrete grooves will cause the leakage of soft asphalt in the subsequent pouring, and it is difficult to clean up; it is very effective to use channel steel instead of concrete grooves, but due to the pre-embedded fixings and connections The parts are designed as one piece, and the connecting parts should protrude out of the section during pouring, so it is difficult to construct the first-stage concrete section, and the connecting parts must be cut off along the section after pouring asphalt, resulting in waste

Abstract

The invention relates to an underground (underwater) building waterproof device and particularly relates to a concrete engineering expansion joint vertical sealing up structure fixing member and an application thereof. The concrete engineering expansion joint vertical sealing up structure fixing member comprises a U-shaped embedded part formed by an embedded part A and an embedded part B, wherein the embedded part is provided with a connection pipe, the connection pipe is provided with an inner thread and is in threaded connection with a connection member, slab iron is fixed to the connection member through a nut into a whole so as to fix a vertical sealing up steel channel at the position of a concrete fracture surface, asphalt is poured into the steel channel, and the connection member and the slab iron are disassembled after cooling and maintained and collected for recycle. By means of the concrete engineering expansion joint vertical sealing up structure fixing member, the problem of water seepage caused by differential settlement or diastrophism of strata in water conservancy projects can be solved, manual work can be saved, construction periods are shortened, and resources are saved.
