AI Technical Summary
Existing waterproofing technologies for diaphragm wall joints are often separated into three parts: construction, installation, and remediation. This leads to mutual interference rather than synergistic effects, and fails to effectively solve leakage problems.
The system employs a multi-layered waterproofing composite joint structure, including rigid connecting components, a detachable anti-flow barrier, and a pre-embedded grouting system. Through a construction method that combines temporal coupling and spatial coordination, it ensures that the joint surface is regular and flat, thoroughly cleaned, and effectively grouted, thus forming a systematic waterproofing solution.
Significantly reduces leakage rate, improves joint waterproofing reliability and construction efficiency, reduces costs, enhances structural integrity, reduces leakage rate by more than 90%, and improves construction efficiency by 20%.
