Abstract

The invention relates to the field of construction of underground diaphragm walls, in particular to a positioning mechanism for prefabricated underground diaphragm walls. A first positioning componentand a second positioning component which are sequentially arranged are arranged on a base, the first positioning component and the second positioning component are connected to the base in a slidingmanner, the first positioning component props against to the side wall of the upper prefabricated underground diaphragm wall, the second positioning component props against to the side wall of the lower prefabricated underground diaphragm wall, a leveling device can level a base board to ensure that the base board is horizontally arranged, the first positioning component and the second positioningcomponent slide relative to the base, so that the bottom end of the upper prefabricated underground diaphragm wall is aligned with the top end of the lower prefabricated underground diaphragm wall, and vertical splicing of the two prefabricated underground diaphragm walls is facilitated.

Description

technical field [0001] The invention relates to the field of underground diaphragm wall construction, in particular to a positioning mechanism and an operating method for a prefabricated underground diaphragm wall. Background technique [0002] The existing underground diaphragm wall is generally constructed in the form of on-site pouring, that is, the groove forming machine is used to form the groove on the ground, and then the pre-bound steel cage is hoisted into the groove, and the concrete slurry is injected into the groove, and the concrete is solidified. Finally, it is closely combined with the steel cage to form an underground continuous wall. However, it is difficult to ensure the proportion of concrete in on-site pouring, and the environment of the pouring site is uncontrollable, and it is very easy for foreign matter to invade the uncured concrete, resulting in the failure of the underground diaphragm wall to meet the design specifications, leaving a safety hazard ...
