AI Technical Summary
Existing I-beams are not securely fixed in the construction of diaphragm walls, are prone to displacement, and have loose connections, which affects the stability and waterproofing performance of the wall.
A connecting mechanism is installed on the flanges on both sides of the main frame I-beam, which extends along the width of the web and forms a stable connection during the pouring process. The connecting mechanism, grout-stopping steel plate, and locking groove are used to ensure the stable connection and overall load-bearing capacity of adjacent unit wall sections.
It achieves stable connection between adjacent unit wall segments, can withstand shear force on vertical joints of underground continuous walls, coordinates uneven settlement, and improves waterproof performance.
