Automatic drainage structure for inner part of slope based on rainfall capacity

Abstract

The invention discloses an automatic drainage structure for the inner part of a slope based on rainfall capacity. The automatic drainage structure comprises a slope, a rain collecting device, a firstdrainage pipe, a second drainage pipe, a three-way pipe and a third drainage pipe, wherein a drainage ditch is formed in the bottom of the slope, a drainage hole is formed in the surface of the slope,the rain collecting device is arranged at the top of the slope, the first drainage pipe is connected with the rail collecting device, the second drainage pipe is connected with the drainage hole, thethird drainage pipe is connected with the drainage ditch, and the first drainage pipe, the second drainage pipe and the third drainage pipe are connected through the three-way pipe. According to theautomatic drainage structure, rainwater is collected by the rain collecting device, the rainwater collected by the rail collecting device reaches the elevation and is automatically discharged throughthe drainage pipes, thus a siphon is started to discharge the accumulated water in the drainage hole, the water level inside the slope is lowered, and landslide disaster caused by the overhigh underground water level in the slope is prevented.

Description

technical field [0001] The invention relates to the technical field of slope drainage, in particular to an automatic drainage structure inside a slope based on rainfall Background technique [0002] Rainfall infiltration causes the groundwater level of the slope to rise, which is likely to induce landslide disasters. It is of great significance to drain the groundwater of the slope body in time and control the groundwater level in the slope below the safe water level to prevent the occurrence of landslide disasters. Siphon is a physical phenomenon that uses the force of liquid level difference to promote liquid flow. The siphon flow process and flow rate are automatically controlled by liquid level changes. These physical characteristics are very in line with the needs of slope drainage and are suitable for popularization and application in slope drainage. . [0003] The initial state of the siphon is full of air, and the siphon requires external force to fill the siphon w...

AI Technical Summary

Problems solved by technology

Due to the intermittent, slow flow and high lift characteristics of the slope siphon drainage process, air will be precipitated during the siphon process and the long-term stop flow process, and the accumulation of air in the pipe will cause the siphon to be interrupted

If the groundwater in the slope is low, frequent pumping to start the siphon will cause waste of energy and water resources. If the groundwater in the slope is high, but the siphon is not activated in time, it may induce landslide disasters
