Embedded water permeable plate water collection siphon drainage method for side slope ground water interception

Abstract

The invention discloses an embedded water permeable plate water collection siphon drainage method for side slope ground water interception. A groove is excavated on the upper middle part of a side slope, a water permeable plate is embedded into the groove, ground water on a shallow surface layer of the side slope is introduced into a water collecting pipe at the bottom of the water permeable plate, and the collected ground water is discharged from the surface of the side slope by a siphon. By the method, infiltrated ground water on the upper part of the side slope can be effectively intercepted, the ground water level of a slope body on the downstream side of an interception area is reduced, the construction cost of engineering for keeping the side slope stable is low, the workload of earth-rock excavation related in the treatment process is low, the implementation process of treatment engineering is simple and practicable, the drainage measure is high in reliability and adaptability and is flexibly used, power is not needed in the drainage process, and the drainage process is not required to be frequently managed or maintained.

Description

technical field [0001] The invention relates to a shallow groundwater interception technology for slopes, in particular to an interception and drainage suitable for gravel soil slopes, which can prevent the rise of groundwater levels in potential landslide areas by reducing the seepage of groundwater from upstream slopes to downstream slopes drainage method. Background technique [0002] Landslide disasters often cause great loss of life and property. Most landslides are induced by rising groundwater levels caused by rainfall. If an effective interception and drainage system can be built in the middle and upper part of the slope to reduce the seepage of groundwater in the upper part of the slope to recharge the potential landslide area along the lower part of the slope, most landslide disasters can be effectively prevented and the geological environment safety in hilly areas can be improved.

AI Technical Summary

Problems solved by technology

[0003] The current interception and drainage measures for slopes are mainly surface drainage ditch and blind drainage ditch. The main problems of them are: (1) Drainage ditch and blind drainage ditch have high requirements on the drainage environment of the slope, and many slopes often lack favorable terrain (2) The surface drainage ditch can only intercept surface water, but because the rainfall will quickly infiltrate into the slope body, the surface drainage ditch cannot intercept the infiltration of the slope. Groundwater, so the interception and drainage effect of the surface drainage ditch is poor, and because the rock and soil on the surface of the slope are loose, local deformation often occurs, which easily leads to cracking of the surface drainage ditch, causing the water in the surface drainage ditch to infiltrate concentratedly, causing local damage and drainage ditch (3) The drainage blind ditch has high requirements on the backfill soil, and it is necessary to ensure the anti-seepage of the ditch bottom and the good permeability of the ditch body, so the construction is difficult. At the same time, the blind drainage ditch should ensure a reasonable continuous slope. In engineering practice often difficult to satisfy
