The invention relates to the field of underground diaphragm wall construction, in particular to an assembly method of a prefabricated underground diaphragm wall, which has a first underground diaphragm wall assembly in a positive trapezoidal shape and a second underground diaphragm wall assembly in an inverted trapezoidal shape, and the first underground diaphragm wall assembly is adjusted by a positioning mechanism. The verticality of the underground diaphragm wall assembly and the second underground diaphragm wall assembly in the groove, and the first underground diaphragm wall assembly and the second underground diaphragm wall assembly are connected and arranged, the prefabricated first underground diaphragm wall assembly and the second underground diaphragm wall assembly The casting quality of the diaphragm wall assembly can be ensured, and the method can improve the construction efficiency on site, and the alternate arrangement of the first underground diaphragm wall assembly and the second underground diaphragm wall assembly can also improve the connection tightness of the connection between the two.
Description
technical field [0001] The invention relates to the field of underground continuous wall construction, in particular to a method for assembling a prefabricated underground continuous wall. Background technique [0002] The existing underground diaphragm wall is generally constructed in the form of on-site pouring, that is, the groove forming operation is first performed on the ground by a groove forming machine, and then the pre-bound steel cage is hoisted into the groove, and the concrete slurry is injected into the groove, and the concrete solidifies. Then it is closely combined with the steel cage and forms an underground continuous wall. However, it is difficult to ensure the proportion of concrete for on-site pouring, and the environment of the pouring site is uncontrollable, and it is very easy for foreign objects to invade into the uncured concrete, resulting in the failure of the underground diaphragm wall to meet the design indicators, leaving a safety hazard for su...
