Abstract
The invention provides a lateral movably-connecting combined joint pipe of a diaphram wall. The movably-connecting combined joint pipe is mutually connected by buckles fixed on two independent joint pipes to form a combined joint pipe, and can be extracted by pulling the two independent joint pipes at the same position or malposition. The joint pipe has the advantages of being especially suitable for solving the problem of the treatment on the joints of the joint pipe of the ultra-thick diaphram wall and sharing the two independent joint pipes so as to greatly bring convenience to the production, transportation and filed operations of the joint pipe. By adopting the occlusion connecting mode, the joint pipe can be extracted at malposition, thereby effectively reducing the risk that the joint pipe cannot be extracted due to overlarge extraction force, reducing the construction difficulty of extracting, ensuring the leakproofness of the diaphram wall joint and effectively avoiding the possibility of the circumferential motion of concrete and the potential hazards of water leakage of the joint seam.
