[0002] The underground diaphragm wall is a commonly used enclosure structure in foundation pit engineering. It often needs to be poured in advance after the reinforcement cage is lowered into grooves. The traditional cast-in-place method has the following disadvantages: 1. It is difficult to ensure the construction of the underground diaphragm wall in the field 2. The cast-in-place construction is time-consuming and laborious. It is necessary to hang the reinforcement cage first and then pour the concrete. The process is complicated; 3. When the geological conditions are poor, the joints of the ground connection walls are also prone to seepage Water leakage affects the overall safety of the foundation pit

The invention provides a prefabricated underground diaphragm wall. The prefabricated underground diaphragm wall comprises a prefabricated underground diaphragm wall body and a locking notch assembly; a plurality of rectangular holes are formed in the middle of the prefabricated underground diaphragm wall body at intervals in the extending direction of the prefabricated underground diaphragm wall body; a plurality of hoisting holes are formed in the prefabricated underground diaphragm wall body at intervals in the extending direction of the prefabricated underground diaphragm wall body and vertically formed along the prefabricated underground diaphragm wall body; and the locking notch assembly comprises a male locking notch and a female locking notch which are formed in the two ends of the prefabricated underground diaphragm wall body correspondingly. The invention further provides a fabricated underground diaphragm wall structure and a construction method. The male locking notch and the female locking notch which are formed in the two ends of the prefabricated underground diaphragm wall body are connected and assembled with the adjacent prefabricated underground diaphragm wall body to form a whole, accurate positioning of splicing of adjacent prefabricated underground diaphragm walls is guaranteed, meanwhile, joints between the prefabricated underground diaphragm walls are waterproof, and the overall safety of the fabricated underground diaphragm wall structure is improved.
Description
technical field [0001] The invention belongs to the technical field of underground structure engineering, and in particular relates to a prefabricated underground diaphragm wall, an assembled underground diaphragm wall structure and a construction method. Background technique [0002] The underground diaphragm wall is a commonly used enclosure structure in foundation pit engineering. It often needs to be poured in advance after troughing and lowering the steel cage. The traditional cast-in-place method has the following disadvantages: 1. It is difficult to ensure the construction of the underground diaphragm wall in the field 2. The cast-in-place construction is time-consuming and laborious. It is necessary to hang the reinforcement cage first and then pour the concrete. The process is complicated; 3. The joints of the ground connection wall are also prone to seepage when the geological conditions are poor. Water leakage affects the overall safety of the foundation pit. Co...
