Description

Technical Field

[0001] This utility model relates to the field of corner overlap technology, specifically a reinforced corner overlap structure for TRD waterstop curtains. Background Technology

[0002] Water-stop curtain is a concept encompassing a series of water-stopping systems around the main structure of an engineering project. It refers to a continuous water-stopping system used to prevent or reduce the inflow of groundwater into the foundation pit from its side walls and bottom. The TRD method involves inserting a cutting box equipped with a cutting chain and cutter head, meeting the design depth, into the ground. While longitudinally cutting and laterally advancing to form a trench, cement grout is injected into the foundation to achieve thorough mixing with the original foundation, forming a continuous wall of uniform thickness underground.

[0003] In response, Chinese Patent Application Publication No. CN118048938A discloses a corner-stopping steel plate structure, belonging to the field of building construction technology. It includes a steel plate body, flexible corner connectors, and a supporting structure. Each corner connector has a vertical mounting groove, within which a connecting plate is installed. The ends of the connecting plates have connecting grooves that engage with the steel plate body. The supporting structure includes a base with support rods at both ends. The length of the support rods is adjustable, and each end of the support rod is hinged to a mounting seat, which is detachably connected to the side wall of the corresponding connecting plate. A support rod slidably mounted on the base, facing the corner connector, is provided. The base has pins to restrict the sliding of the support rods, and the ends of the support rods have a clamping structure that abuts against the corner connector. The purpose is to solve the problem of potential leakage at the overlapping joints of non-straight sections of the water-stopping steel plate welded on-site.

[0004] However, in actual use, some water-stopping components are used in the water-stop curtain. However, the corner water-stopping component in the above patent has poor overall stability when it is connected to the connecting plate. Moreover, it is an integral connection, which is more troublesome to install. At the same time, the sealing performance is poor when it is connected to other components, which will affect the subsequent water-stopping effect. In addition, the upward connection at the corner also requires sealing and stability. Therefore, improving and perfecting the above problems has become an urgent problem to be solved.
