When we install the lifting column, we need to conduct a comprehensive investigation on its replacement. The terrain, whether the drainage is smooth and whether it is a rainy area are the main factors that determine whether drainage wells need to be made.
The purpose of installing the lifting column as the drainage well is to discharge the rainwater that cannot penetrate into the ground in time to avoid the long-term immersion of the lifting column.
If it is a higher terrain, and relatively perfect drainage conditions, you can do regular seepage layer can be.
Drainage wells are mostly used in the foundation where the surface weak permeable layer and the lower strong permeable layer are relatively deep, or the foundation where the aquifer is layered significantly and there are many lenses and strong water-bearing zones.
Since the embankment foundations of most projects are multi-layer foundations and the geological conditions are complex, drainage wells are widely used in the application of drainage measures.
The seepage guiding principle is to guide the seepage flow from the upstream of the dam body into the drainage pressure relief well through the filter pipe to prevent the seepage flow from flowing downstream, so as to achieve the purpose of rapidly reducing the pressure head, protecting the stability of the dam and reducing the underground water level downstream.
For the drainage well system, the well system shall be located as close as possible to the toe of the downstream dam. For the well diameter, it mainly depends on the construction conditions, well pipe materials and the thickness of the inverted filter layer.
The commonly used well pipe diameter is 20~40cm, and the effective well diameter after considering the inverted filter layer is usually 40~60cm.
The penetration of drainage wells is a very important factor, when the penetration is small, the drainage decompression effect is poor.
During the construction of the lifting column, if drainage is done, the construction cost will increase a lot, so users need to fully consider and calculate. Regarding whether to do drainage wells, in the long-term use of lifting column consideration, if there are conditions or do the best.
