System for automatically draining water on side slope and method therefor

Abstract

The invention provides a system for automatically draining water on a slide slope and a method therefor. The system comprises an energy storing device, a triggering device and a drainage device, wherein the energy storing device comprises a water storage tank, an energy storage tank, a water outlet pipe, a water stopping plug and the like; the triggering device comprises a suspension cylinder, a rigid suspension cylinder rod, a guide cylinder, an elastic connecting rope, a guide rod, a floating ball, a rigid pressing rod and the like; and the drainage device comprises a water pumping pipe, a drainage pipe and the like. The system is placed at the upper portion of a converging hole of a step of the side slope, when a water level in the converging hole reaches a designed automatic drainage starting water level, the triggering device is started, the water stopping plug is opened, water stored in the energy storage tank flows into the drainage pipe, and when the drainage pipe is filled with the stored water and the water stopping plug is closed, a siphonage phenomenon appears in the system, and accumulated water in the converging hole is discharged to the lower portion of the side slope through the water pumping pipe and the drainage pipe. According to the system, the structure is simple, energy sources such as electric energy, solar energy and wind energy are not required, the system is provided with no precise component or quick-wear part, good adaptability for drainage of various side slopes in the wild is achieved, drainage construction is achieved, the management is simple, the cost is low, and the drainage effect is good.

Description

technical field [0001] The present invention relates to an automatic drainage system, in particular to an automatic drainage system for slopes that can be applied to drain open-air slopes, road and railway slopes, and hydropower slopes to realize the automatic drainage of slopes. . 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 ...

Problems solved by technology

The first method is a commonly used drainage method. Its disadvantage is that the construction cost is high, and drainage holes must be constructed in time during the formation of the slope. If the optimal construction period is missed, once the slope is formed, there is no operating platform. It is impossible to add drainage holes. The second method is suitable for slope drainage where the distance between the slope surface and the drainage area is relatively long, the drainage distance of the horizontal hole is too long, and the construction is extremely difficult; or there is water seepage in the later stage of slope excavation. It is difficult for personnel and equipment to work on the steep slope that has been formed, and it can only be constructed in the area of ​​the slope step

The disadvantages of using vertical holes for drainage are as follows: (1) Usually, submersible pumps are used to pump out the accumulated water seeping from the drainage holes. Not only does it take a lot of manpower and material resources to erect power cables in the open pit, but also special personnel must be responsible for the submersible pumps. If it is the long-term drainage of the road and railway slopes in the field, the implementation of this method is more difficult; (2) the head of the general submersible pump is proportional to the diameter of the pump body, and the head of the small volume pump is small, so a large volume pump must be used to meet the side Therefore, large-diameter holes such as φ265mm must be used, which have defects such as high drilling cost and slow construction speed; (3) The submersible pumps installed in the vertical drainage holes are generally clean water pumps (slurry pumps are large in volume). There is a lot of mud inside, and the loss is very large; (4) The infiltration of accumulated water in the vertical drainage holes is a slow process, while pumping water is a relatively fast process. If the management is not good, the water pump is easy to burn due to idling
