Underground Diaphragm Wall Hinged Joints

Abstract

The invention relates to underground buildings, in particular to a hinged joint of an underground diaphragm wall, which is fixedly connected to the concave end of the reinforcement cage of the diaphragm wall, and is characterized in that the joint consists of a hinged pipe, wing plates located on both sides of the hinged pipe and It is composed of a hemming part located at the edge of the wing plate. The hinged tube is approximately Ω-shaped with a partial opening. The two ends of the opening are respectively connected to the wing plate. Shaped hinged tube can be used as a guide channel for objects to be placed in the later stage. It can not only be used as a guide when cleaning the wall brusher to ensure the mud brushing effect, but also can be used as a guide device when the lock tube is placed to ensure that the lock tube The accurate sinking position improves the work efficiency and project quality; it is more convenient for cleaning the surface, and it is also convenient for the extraction of the locking pipe, which is a good solution to the problem of stagnation in the contact surface of the first pouring trough or partial mud cleaning. Problems, while making the seams tighter, can better prevent leakage.

Description

technical field [0001] The invention relates to underground buildings, in particular to a hinged joint of an underground continuous wall. Background technique [0002] The compactness of the joints of the underground diaphragm wall groove section is very important. If there is a problem with the construction quality of the joints, it will lead to leakage of the underground structure of the project, which will directly affect the use of the underground structure of the project. Leakage will not only affect the use of the building, but also It is very difficult to deal with, so effective measures must be taken during the construction of unit wall joints to solve the hidden problems in advance, so as to avoid future troubles. As an integral part of the underground main structure, the underground diaphragm wall must be permanent and durable, with no seepage, no leakage, and balanced stress in the whole structure. The walls of each unit groove section of the underground diaphrag...

AI Technical Summary

Problems solved by technology

At present, most of the domestic use lock pipe joints and I-shaped prefabricated joints. During the construction, when the unit groove section is placed during the excavation process of the groove forming machine, it is necessary to use a wall brush to clean and brush the contact surface of the first pouring groove section. The surface of the contact surface is the side of the steel cage, not the overall smooth surface. At the same time, because the steel cage is bulky and deep, it is difficult to keep a fixed distance between the wall brusher and the cleaning surface when cleaning and scrubbing up and down. The force on the cleaning surface is uneven, and the cleaning effect is difficult to guarantee. Due to the above-mentioned problems in the cleaning work, it is difficult to clean the sediment or local mud at the joints of the groove section, which will easily lead to water leakage in the later stage.
