Stratum interface residual water draining and dewatering device
The invention discloses a stratigraphic interface residual water draining and dewatering device which comprises a vertical well vertically arranged in a stratigraphic interface needing draining and dewatering; the inclined wells are obliquely and downwards arranged in the stratum interface in a penetrating mode and communicate with the middles of the vertical wells, and when the number of the inclined wells is multiple, the multiple inclined wells are symmetrically arranged with the vertical wells as the circle center; and the negative pressure generation unit is connected with one end of the inclined well, and the negative pressure generation unit can perform air exhaust and pressure reduction on the inclined well. Residual water on the stratum interface can be effectively drained, and the conditions that the soil body is soft, and the bearing capacity is insufficient are avoided. In addition, the method has the advantages of being rapid in construction, simple in process, short in construction period, recyclable in material, energy-saving, environment-friendly and the like, can be used for conventional stratum drainage, and can accelerate drainage and precipitation speed and shorten drainage and precipitation construction period.
本发明公开了一种地层界面残留水疏干降水装置，包括：竖向井，竖直地设置在需要疏干降水的地层界面内；至少一个倾斜井，所述倾斜井倾斜向下穿设在所述地层界面内，并与所述竖向井的中部相连通，当所述倾斜井的数量为多个时，多个所述倾斜井以所述竖向井为圆心对称布置；负压发生单元，与所述倾斜井的一端相连接，所述负压发生单元能够对所述倾斜井进行抽气减压。本发明能有效疏干地层界面残留水，避免出现土体松软，承载力不足等情况。并且本发明还具有施工迅速、工艺简单、工期短、材料可回收利用节能环保等优点，此外，也可用于常规地层疏干，可加快疏干降水速率，减少疏干降水工期。
