Connector box used for underground diaphragm wall steel-rubber connector and construction method

Abstract

The invention relates to a connector box used for an underground diaphragm wall steel-rubber connector and a construction method, and belongs to the technical field of building construction. The connector box and the construction method are used for solving the problems that as for a circular connector pipe, an excavation dark region exists or the wall brushing technology needs to be additionally arranged, and therefore the number of construction technologies is increased. The connector box comprises a horseshoe fore shaft pipe capable of being lifted in a pit of a construction trough section. An arc-shaped end face is formed at the end, close to the front portion of the construction trough section, of the horseshoe fore shaft pipe in the width direction of the construction trough section, and a rectangular end face is formed at the end, close to the back portion of the construction trough section, of the horseshoe fore shaft pipe in the width direction of the construction trough section. A groove is formed in the end, close to the front portion of the construction trough section, of the horseshoe fore shaft pipe in the length direction of the construction trough section, and a rubber water stop sheet is embedded into the groove. The construction method includes the steps of 1, excavating the front portion of the construction trough section, and placing the connector box; 2, placing a steel reinforcing cage, and pouring the cage with concrete; 6, excavating the back portion of the construction trough section; 4, removing the horseshoe fore shaft pipe in a pulling mode.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a joint box used for steel-rubber joints of an underground continuous wall and a construction method. Background technique [0002] During the construction of the foundation pit, it is generally necessary to construct the water and soil retaining structure in advance. Due to its advantages of high rigidity, good integrity and strong anti-seepage ability, the underground diaphragm wall has been widely used in deep foundation pit engineering as a foundation pit enclosure structure. During the construction of the underground diaphragm wall, the soil is excavated one by one, the steel cage is hoisted, and the concrete is poured to form the wall. The joint box of the wall width is used to connect the adjacent two unit groove sections, such as the front construction groove section and the rear section. Construction tank section. When the underground diaphrag...

Problems solved by technology

[0005] The purpose of the present invention is to provide a joint box and construction method for underground diaphragm wall steel-rubber joints, to solve the problem of excavation in the traditional circular joint pipe for underground diaphragm wall or when there is excavation on the back of the circular joint pipe. Dark areas, or the need to add wall brushing technology in the joint area, resulting in increased construction difficulty
