AI Technical Summary

Technical Problem

The existing foundation pit support structure and drainage facilities interfere with each other in the confined space, resulting in construction difficulties and low drainage efficiency. Furthermore, the lack of fire rescue scenario design poses safety hazards.

Method used

The support device, which uses hydraulic support rods, combined with filter components and drainage devices, can filter and drain water accumulated in the pit. The hydraulic support rods keep the support steel plate tightly attached to the pit sidewall. After the water is collected in the water collection chamber, it is pumped out by the drainage pump, avoiding the repeated occupation of space.

Benefits of technology

Effective use of space in confined areas improves drainage efficiency, reduces construction difficulty, ensures timely removal of accumulated water during fire rescue operations, and reduces safety hazards.

Abstract

This invention relates to the field of building construction, specifically to a device for simultaneous support and drainage of foundation pits in building construction. The device includes a hydraulic support rod, with support devices for supporting the foundation pit fixedly installed at both ends. Each support device contains a drainage device for draining accumulated water from the foundation pit. The invention applies thrust to both sides through the hydraulic support rod, ensuring the support steel plate tightly adheres to the sidewall of the foundation pit. When water seeps from the sidewall of the foundation pit or accumulates due to rainfall, the water first passes through the filter screen and grid screen in the filtration assembly before entering the water collection chamber of the support steel plate for temporary storage. When the water level in the collection chamber reaches a certain height, the operator starts the drainage pump, which pumps out the accumulated water from the collection chamber through connecting pipes, insert pipes, and filter heads.
