Embodiment Construction
[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] combine Figure 1 to Figure 6 As shown, the locking mechanism of the prefabricated underground continuous wall of the present invention is schematically shown, including the active plug assembly 1 and the passive plug assembly 2 .
[0030] The active plug assembly 1 includes a locking joint 11 and a guide rail and a driving device 12 fixedly connected to the first prefabricated underground continuous wall 3. The guide rail is arranged horizontally. The fixed end of the locking joint 11 is slidably connected to the guide rail, and the movable end of the driving device 12 is Connected to the locking joint 11, the driving device 12 can drive the locking joint 11 to sl...

The invention relates to the field of underground continuous wall structures, in particular to a locking mechanism for prefabricating underground continuous walls. The locking mechanism is provided with an active inserting assembly and a passive inserted assembly. A locking connector of the active inserting assembly can slide along a guide rail under driving of a drive device, and thus the lockingconnector can move toward the outer side of a first prefabricated underground continuous wall in the horizontal direction. An anti-falling part is movably arranged in a locking inserting groove of the passive inserted assembly. After the first prefabricated underground continuous wall and a second prefabricated underground continuous wall are arranged horizontally next to each other, the lockingconnector extends into the locking inserting groove of the second prefabricated underground continuous wall, the anti-falling part is connected to the locking connector in an abutting-against manner so as to stop the locking connector from being separated from the locking inserting groove, the two adjacent prefabricated underground continuous walls can be connected rapidly, and the locking connector and the locking inserting groove can effectively improve the tensile property of the connecting portion of the underground continuous walls.
Description
technical field [0001] The invention relates to the field of underground continuous wall structures, in particular to a locking mechanism for 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 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 for subsequent construction ...
