Suspended type foundation pit drainage system and using method thereof

Abstract

The invention provides a suspended type foundation pit drainage system and a using method thereof. The suspended type foundation pit drainage system comprises a fixed supporting frame, a drainage assembly and a water pump, wherein the fixed supporting frame is arranged on the side wall of a foundation pit; the drainage assembly arranged on the fixed supporting frame, one end of the drainage assembly extends into water in the foundation pit, and the other end of the drainage assembly is connected to an earth surface drainage trench; and the water pump is connected with the drainage assembly, and by means of the water pump, the water in the foundation pit is drained into the earth surface drainage trench through the drainage assembly. According to the suspended type foundation pit drainage system, the drainage assembly of which one end extends into the water in the foundation pit can touch the bottom of the foundation pit as much as possible, so that the water in the foundation pit can be rapidly and effectively drained out of the foundation pit, and accordingly the safety of the side wall of the foundation pit is improved.

Description

Technical field [0001] The invention belongs to the field of foundation pit engineering construction, and relates to a drainage system, in particular to a suspended foundation pit drainage system and a use method thereof. Background technique [0002] During the construction of the foundation pit, the groundwater level can be lowered below the bottom of the pit by means of the foundation pit to meet the construction requirements. However, due to the impact of natural rainfall, it is still necessary to set up an open drain at the bottom of the pit to drain rainwater out of the pit. Moreover, when the pile foundation is constructed with manual digging piles or there are many pits in the pit, it is also necessary to drain the groundwater in the local deep pit to the outside of the pit. [0003] The open drainage method of water collection is usually to set up drainage ditch and water collection well around the foundation pit. The water in the pit naturally flows into the drainage dit...

AI Technical Summary

Problems solved by technology

This method is inefficient when the foundation pit area is large, and cannot solve the drainage problem of local deep pits

If the local deep pit is directly pumped out of the pit or to the drainage ditch, it will cause chaos on the site and waste of resources, affecting the progress and safety of the project
