Description

Technical Field

[0001] The utility model relates to the technical field of post-cast strip structures, in particular to an advanced water-stop post-cast strip structure. Background Art

[0002] In the early days of underground engineering, simple waterproofing measures such as waterproof coatings and waterproof layers were mainly adopted. However, these measures had limited effectiveness in dealing with high water levels and high water pressures. The concept of waterstops was introduced, usually by embedding rubber waterstops or plastic waterstops in concrete to prevent water leakage. However, the technology was relatively simple. As engineering needs increased, the materials and technologies of waterstops were improved. More advanced materials such as high-performance synthetic rubber and polymers, as well as improved embedding methods, were adopted. The advanced waterstop post-casting strip structure consists of a waterstop, post-casting strips, temporary supports, construction supports, and connecting parts. However, the existing advanced waterstop post-casting strip structure is prone to displacement or falling off during the concrete pouring process during use, making it difficult to accurately align the various parts of the post-casting strip structure, resulting in poor waterproofing performance of the advanced waterstop post-casting strip structure. Therefore, the above technical problems need to be solved. Utility Model Content
