Shoulder-accumulation-slope intelligent drainage system and drainage method

Abstract

The invention discloses a shoulder-accumulation-slope intelligent drainage system and a drainage method which can give consideration to residential water consumption and timely discharge of superfluous underground water in an accumulation. The system comprises a drainage adit located in the rock stratum on the lower portion of the toe of an accumulation slope, and the drainage adit is located below a bedrock-cover interface. The system further comprises a drainage pipe, the upper portion of the drainage pipe is located in the part, above the bedrock-cover interface, of the accumulation, the side wall of the upper portion of the drainage pipe is provided with a plurality of water inlet holes, the side wall of the upper portion of the drainage pipe is wrapped by earthwork cloth, the bottom portion of the drainage pipe is located in the drainage adit, the bottom of the drainage pipe is provided with a drainage hole, and a drainage valve is arranged in the drainage hole; a controller and a sensor are further arranged in the drainage adit, the controller is used for controlling opening and closing of the drainage valve, the sensor is used for detection water pressure in the drainage pipe, and the sensor is connected with the controller. Whether the drainage valve is opened for drainage can be judged through the controller according to detection signals of the sensor.

Description

technical field [0001] The invention relates to an intelligent drainage system for valley shoulder accumulation body slopes, and also relates to a drainage method using the drainage system. Background technique [0002] Drainage is one of the important engineering treatment measures in the comprehensive management of valley shoulder accumulation slope. There are generally two types of drainage measures for accumulation slopes: superficial drainage and deep drainage. The deep drainage is mainly to discharge the underground water stored in the accumulation body. If the groundwater level is too high, it will reduce the safety factor of the slope and even cause the slope to become unstable; but for the situation where people live, the water level will be too low to affect the living and production water of local residents; The properties change, resulting in local subsidence and deformation of the surface. [0003] At present, for the deep water treatment of inhabited valley s...
