Slope drainage system

Abstract

The invention discloses a slope drainage system. According to the key points of the technical scheme, the slope drainage system comprises a water seepage pipe, a water storage tank, a water replenishing tank, a drain control circuit and a water replenishing control circuit, the water seepage pipe is provided with water seepage holes, the water seepage pipe and the water storage tank communicate with a water suction pipe, the water storage tank communicates with a drainage pipe, the water replenishing tank and the water storage tank communicate with a drain pipe, the drain pipe is provided witha first solenoid valve, a water replenishing pipe is provided with a second solenoid valve, the water suction pipe is provided with a one-way water inlet valve, the water storage tank communicates with a one-way vent valve, the drain control circuit controls the first solenoid valve to be opened, and the water replenishing control circuit controls the second solenoid valve to be opened. When accumulated water on a slope is increased, the drain control circuit controls the first solenoid valve to be opened, water in the water replenishing tank enters the water storage tank through the drain pipe, and the water in the water storage tank flows out through the drainage pipe, so that negative pressure is generated in the water storage tank, the water suction pipe sucks the accumulated water inthe water seepage pipe into the water storage tank, circulation is conducted in this way, the accumulated water on the slope can be drained, and thus the stability of the slope is improved.

Description

technical field [0001] The present invention relates to a side slope drainage system, more specifically, it relates to a side slope drainage system. Background technique [0002] Open-air slopes, road and railway slopes, etc. are often rich in a large amount of accumulated water. The sources mainly include rainwater infiltration, upper slope or mountain water infiltration, and even stream water infiltration. The accumulated water in the slope is very unfavorable to the stability of the slope, mainly in the following aspects: (1) The strength of the general rock in the dry state is often 1-2 times that of the saturated state, so the stability of the dry slope is obviously higher than that of the rock. Water-bearing slope; (2) Many rocks such as granite porphyry, mudstone, argillaceous conglomerate, and montmorillonite have the characteristics of cementation and disintegration, so the strength of the rock mass decreases rapidly, and the stability of the slope decreases accordi...

Problems solved by technology

The accumulated water in the slope is very unfavorable to the stability of the slope, which is mainly manifested in: (1) The strength of the general rock in the dry state is often 1-2 times that of the saturated state, so the stability of the dry slope is obviously higher than that of the rock. Water-bearing slope; (2) Many rocks, such as granite porphyry, mudstone, argillaceous conglomerate, and montmorillonite, have the characteristics of cementation and disintegration, so the strength of the rock mass decreases rapidly, and the stability of the slope decreases accordingly (3) Structural belt is often the key to slope instability. The rock mass in the structural belt is broken, contains fault gouge, and has obvious characteristics of rain cementization, and its frictional resistance will decrease rapidly; (4) Slope An increase in the internal water content will lead to an increase in the weight of the slope and an increase in the tendency of instability
