AI Technical Summary
During construction near an operational railway line, gaps between the bottom of conventional foundation pit enclosures and the ground cause surface water to flow into the pit, posing a safety hazard. Furthermore, sandbag sealing is prone to breakage and becomes floating debris, affecting railway operations.
The prefabricated foundation pit enclosure is adopted, with a flexible water storage belt suspended at the bottom of the outer side. The gaps are filled and sealed by water injection. The flexible water storage belt has a protective layer to prevent cracking, and the connecting structure is fixed to the enclosure body.
This effectively prevents surface water from flowing into the foundation pit, ensuring construction safety, preventing the water storage belt from being damaged and becoming floating debris, and ensuring the safe operation of existing railways.
