This invention relates to a drainage well system for a foundation pit suitable for a ground-mounted waterproof curtain. The system includes a drainage well body positioned within the backfill area of ​​the foundation pit, located between the main structural wall and the ground-mounted waterproof curtain. The drainage well bodies are arranged at predetermined intervals within the backfill area. The outer facade of the main structural wall is provided with a waterproof layer. Each drainage well body includes a non-porous solid pipe section and a perforated filter section located below the non-porous solid pipe section. The perforated filter section is externally covered with a filter layer, and the surrounding hollow spaces of the filter layer are filled with graded filter media. The lower end of the drainage well body is positioned below the bottom of the foundation pit and above the stable waterproof layer. A pumping system is installed within the drainage well body to promptly pump out seepage water from the foundation pit when the water level within the drainage well body rises to a preset level. The pumping system is connected to the municipal stormwater drainage network. This invention can serve as a long-term drainage facility and also enables water resource reuse.
