Abstract

The invention relates to a prefabricated dense rib cavity wallboard, and belongs to the technical field of foundation pit wallboards, the prefabricated dense rib cavity wallboard comprises a wall body, a cavity is formed in the wall body, a vacuum pump is fixed on the top of the wall body, and a plurality of water collecting pipes are fixed on the surface of the wall body; an expansion type water stop strip is fixed in the pipe wall of the water collecting pipe; a first switch moving plate is arranged on the water collecting pipe in a sliding mode in the axial direction. The first switch moving plate is fixedly connected with the expansion type water stop strip. A switch stator plate I which can be electrically contacted with the switch rotor plate I is fixed in the water collecting pipe; the first switch moving plate is electrically connected with the vacuum pump. The first switch stator plate can be electrically connected with the storage battery. The device has the effect of reacting accumulated water in the foundation pit.

Description

technical field [0001] The present application relates to the field of foundation pit wall panels, in particular to a prefabricated dense rib cavity wall panel. Background technique [0002] At present, when the foundation pit is excavated, the aquifer of the soil body is cut off, and the groundwater will continuously infiltrate the foundation pit, causing quicksand, instability of the slope or a decrease in the bearing capacity of the foundation. [0003] For related technology, refer to the Chinese invention patent with the authorized announcement number CN107794931B, which discloses a foundation pit support structure, including a support plate with a cavity, the upper side of the support plate is connected with a vacuum pump, and the side of the support plate is provided with an insert. A support pipe in the soil, the support pipe is communicated with the cavity, and a water absorption hole is arranged on the pipe wall of the support pipe. The support plate is used to su...
