Serial water-collecting well drainage device and method for landslide control

Abstract

The invention discloses a serial water-collecting well drainage device for landslide control. The serial water-collecting well drainage device for the landslide control comprises a plurality of water-collecting wells and a plurality of drainage pipes; each water-collecting well is arranged in the oblique direction of a landslide from the top to bottom; one drainage pipe is connected with the bottom of one water-collecting well; and one drainage pipe drains underground water after collecting the underground water collected by one water-collecting well. The invention further discloses a serial water-collecting well drainage method for the landslide control. The serial water-collecting well drainage method for the landslide control comprises the following steps that one, a landslide mass is surveyed, an underground water enriching area is selected, and the multiple water-collecting wells are formed in the underground water enriching area; and two, the multiple drainage pipes are adopted according to the positions of the multiple water-collecting wells, and the underground water in one water-collecting well is drained by the drainage pipe after being collected in the drainage pipe communicating with the bottom of the water-collecting well. With the adoption of a mode that the water-collecting wells are in series connection, the serial water-collecting well drainage device and method for the landslide control have the beneficial effects that the underground water collected by the water-collecting wells is rapidly drained.

Description

technical field [0001] The invention relates to the field of landslide control. More specifically, the present invention relates to a drainage device and method for series collection wells for landslide treatment. Background technique [0002] In the treatment of landslides, "control the water first" has become a generally accepted saying, but the existing water control measures mainly stay at the surface level, and there are few drainage measures for groundwater and the effect is not obvious. According to statistics, 95% of landslides are mainly After the rainfall, the rainwater seeps down and the groundwater level rises, which greatly reduces the stability of the landslide. At the same time, in some landslides with rich water and uneven groundwater, the water content is extremely uneven, and the stability varies greatly. It is very unfavorable to the overall stability of the landslide, and it needs to be treated to remove the groundwater in the landslide, so as to avoid t...

[0002] In the treatment of landslides, "control the water first" has become a generally accepted saying, but the existing water control measures mainly stay at the surface level, and there are few drainage measures for groundwater and the effect is not obvious. According to statistics, 95% of landslides are mainly After the rainfall, the rainwater seeps down and the groundwater level rises, which greatly reduces the stability of the landslide. At the same time, in some landslides with rich water and uneven groundwater, the water content is extremely uneven, and the stability varies greatly. It is very unfavorable for the overall stability of the landslide, and it needs to be treated to remove the groundwater in the landslide, so as to avoid the economic losses and safety hazards caused by the slippage of the landslide.
