Treatment scheme for leakage of elevator foundation pit

The treatment scheme of elevator foundation pit leakage is to find out the leakage reason, eliminate the blockage, maintain the drainage system, prevent groundwater infiltration, and check and maintain it regularly.

1. Find out the causes of water seepage: First, determine the causes of water seepage, which may be the rise of groundwater level, rainwater backflow, drainage system failure, etc. Look for the source of leakage through careful observation and inspection.

2. Clear the blockage: If the water seepage is caused by the blockage of the drainage system, you can try to clear the blockage. Use pipe ventilation tools or cleaning agents to remove blockages.

3. Maintenance of drainage system: If there is a leak or damage in the drainage system, it needs to be repaired in time. Repair loopholes or replace damaged parts to ensure the normal operation of the drainage system.

4. Prevent groundwater infiltration: If water seepage is caused by the rise of groundwater level, measures can be taken to prevent groundwater infiltration. For example, install waterproof isolation layer or dig drainage ditch to guide groundwater to a suitable place for discharge.

5. Regular inspection and maintenance: regularly check whether there is water seepage at the bottom of the elevator shaft and carry out necessary maintenance work. If water leakage is found, handle it in time to prevent the problem from getting worse.
