Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit water gushing, and in particular to a rapid blocking device and method for foundation pit water gushing. Background Art

[0002] Pit water inrush refers to the phenomenon of groundwater influx into the foundation pit during excavation due to factors such as high groundwater levels or high groundwater permeability. To prevent pit water inrush from impacting construction, existing rapid sealing methods generally involve installing temporary barriers, such as steel plates or cement boards, at the inflow openings or cracks to prevent groundwater from entering the foundation pit. The blocked groundwater is then pumped out using water pumps.

[0003] A search revealed a patent with the authorized publication number CN209620043U, which discloses a foundation pit baffle. The patent comprises a rectangular steel body with vertical strip-shaped depressions on the body surface, with evenly spaced inward-facing clamping structures fixed by fixing rings between the strip-shaped depressions. Two sealing strips with clamping structures are connected along the long edges of the body via soft connectors at the four corners of the body. A ring of rubber sheet structure is fixed to the outside of the body, with an external cotton velvet waterproof strip added to the inner surface of the rubber sheet. Within the outer cotton velvet waterproof strip, there is another ring of internal cotton velvet waterproof strip structure, with several cords extending outward from the internal cotton velvet waterproof strip. The additional ring of rubber sheet structure with the cotton velvet waterproof strip can overlap each other, which can, to a certain extent, prevent rainwater from the baffle surface from entering the soil.
