Lateral movably-connecting combined joint pipe of diaphram wall

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 suitablefor 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.

Description

technical field [0001] The invention relates to an underground diaphragm wall joint treatment process in the fields of municipal administration, railways, ports, etc., in particular to an underground diaphragm wall transverse live connection combined joint pipe, which is suitable for the treatment of ultra-thick underground diaphragm wall joint pipe joints. Background technique [0002] The main steps in the construction of the underground diaphragm wall are: 1. First construct the guide wall of the underground diaphragm wall and leveling and compacting the site; 2. Use the special trenching equipment for the underground diaphragm wall to carry out the trenching operation, similar to the hole forming of cast-in-place piles; 3. Satisfy the After the design and construction specifications are required, place the circular joint pipe connecting the ground to the wall at the end of the groove section; 4. Lift and lower the processed steel cage; 5. Carry out underwater concrete pou...
