AI Technical Summary
Traditional concrete pipes are inefficient and inaccurate in splicing construction, and lack self-adjustment capabilities during use, making them prone to joint cracking and leakage.
It adopts a design with concave angles, convex angles, and buffer angles, combined with a hollow annular sealing strip and a straight rod structure with lifting lugs, to achieve self-adjustment and precise alignment. The lifting lugs and straight rods work together for hoisting, and the dynamic sealing characteristics of the hollow annular sealing strip are used to adapt to stress changes caused by settlement.
It improves splicing efficiency and accuracy, reduces the risk of interface breakage, maintains the structural stability and sealing of the pipeline system, and extends its service life.
