What is well point precipitation
Well point dewatering is a groundwater control technology widely used in construction projects. It is mainly used to reduce groundwater levels and ensure construction safety and project quality. In recent years, with the acceleration of urbanization and the continuous advancement of infrastructure construction, well point dewatering technology has become one of the hot topics. This article will introduce in detail the definition, principle, application scenarios and technical points of well point precipitation, and attach hot topic data in the past 10 days for reference.
1. Definition and principle of well point precipitation
Wellpoint dewatering is a technology that lowers the groundwater level by arranging a series of wellpoint pipes around the construction area and using vacuum pumps or centrifugal pumps to pump out groundwater. Its core principle is to centrally extract groundwater through negative pressure to reduce the impact of groundwater on construction.
2. Application scenarios of well point precipitation
Well point dewatering technology is widely used in the following scenarios:
| Application scenarios | Specific instructions |
|---|---|
| Foundation pit excavation | Prevent groundwater from influxing into the foundation pit and ensure construction safety |
| underground engineering | Such as subways, tunnels, etc., lowering the groundwater level to facilitate construction |
| foundation treatment | Improve the bearing capacity of the foundation and prevent foundation settlement |
3. Technical key points of well point dewatering
The following points need to be paid attention to when implementing well point dewatering technology:
| Technical points | Detailed description |
|---|---|
| Well point layout | According to geological conditions and construction requirements, reasonably arrange the spacing between well points and tubes |
| Pumping equipment | Choose a suitable vacuum pump or centrifugal pump to ensure water pumping efficiency |
| Maintenance management | Regularly inspect well point pipes and pumping equipment to prevent blockage or failure |
