Problems solved by technology

[0003] A large number of techniques for monitoring landslide surface runoff or surface water flow have been found in previous studies. However, in the monitoring of landslide underwater overflow and seepage, it is rarely seen because of the following important technical difficulties: 1. Landslide overflow seepage velocity and flow rate The value is different due to different seasons, and the value is often larger in the rainy season, less in the dry season, and has the characteristics of a large fluctuation range; 2. Due to the anisotropy of the landslide rock-soil medium, it is difficult to determine the spatial location of the seepage distribution of the landslide underwater overflow , the seepage volume at different locations is different and the distribution is uneven; 3. The underwater environment is complex, and it is difficult to distinguish underwater environments such as swell waves and aquatic organisms by the tracer method using reflective materials, temperature fields, magnetic fields, and electric fields as platforms. The difference from landslide overflow seepage cannot be directly applied
At the same time, when the seepage velocity is high, the sediment washed out is easy to deposit in the equipment and cause blockage
In addition, the waterproof treatment of monitoring equipment, underwater power supply, and the reliability and continuity of monitoring methods are all challenges for the monitoring of landslide underwater overflow and seepage.

Abstract

The invention provides a reservoir landslide underwater surface overflow seepage monitoring device and monitoring method. The monitoring device includes an underwater seepage monitor arranged on an underwater slide body; the underwater seepage monitor includes a load-bearing shell, a diversion pipe, and a mud discharge Cover plate and mud discharge mechanism, the mud discharge mechanism drives the mud discharge cover to switch between the blocked position and the open position, considering the complex environmental factors of underwater seepage monitoring, providing a The multi-functional flow monitor for the seepage outlet of the landslide is provided with a mud discharge hole on the load-bearing shell, and the mud discharge cover is driven by the mud discharge mechanism to the open position, and the silt in the load-bearing shell can be discharged from the mud discharge hole to solve the problem of water The problem of silt accumulation caused by overflow and seepage of landslides. The seepage overflowed by the slide body flows through the confluence chamber and the diversion pipe, and flows into the sedimentation chamber. The flow velocity changes, which is conducive to the accumulation of sediment, and at the same time solves the monitoring stability caused by the impact of environmental water It provides a stable underwater seepage monitoring environment.

Description

technical field [0001] The invention relates to the technical field of landslide monitoring, in particular to a monitoring device and a monitoring method for overflow seepage on the underwater surface of a reservoir landslide. Background technique [0002] The reservoir area has complex geological conditions and frequent geological disasters. Due to the regulation of water storage in reservoirs, the frequency of landslides and bank collapses has increased, which has a serious impact on people's lives and property safety. During the deformation process of the landslide body, the structure will be loosened and the permeability will be enhanced, which will change the seepage field around the landslide body. At the same time, ground fissures and sinkholes develop on the trailing edge of the landslide, so that the surface water (irrigation water and rainfall) can be directly poured into the slope, which induces a large number of landslides. Therefore, spring water is often expo...
