Power-free reverse-water-pressurizing self-recovery slope high-lift siphon drainage system and drainage method

Abstract

The invention relates to a power-free reverse-water-pressurizing self-recovery slope high-lift siphon drainage system and drainage method adaptive to accumulation member slope drainage of rich rainfall areas. The system includes an automatic drainage system and an automatic recovery system. The automatic drainage system comprises a siphon drainage hole, a high-lift siphon drainage tube and a siphon water storage tube; the automatic recovery system comprises a water collecting blind groove, a water collecting case, a water feeding pipe,a two-way water incoming and draining valve and the like. The high-lift siphon drainage system with the lift more than 5cm is utilized, and the excessive underground water in the slope can be drained automatically, efficiently and timely; reverse water feeding is performed on the automatic drainage system by the automatic recovery system to start siphon, the air accumulated in the siphon pipe can be exhausted, and long effective period of a forward siphon system is guaranteed; the system is simple in structure, the power is omitted, the discharging effect is fine, the continuity and applicability are high, and the maintaining cost is low.

Description

technical field [0001] The invention belongs to the technical field of slope drainage, and in particular relates to a power-free self-recovering slope high-lift siphon drainage system and a drainage method, which are especially suitable for drainage of accumulated soil slopes in areas with abundant rainfall. Background technique [0002] Rainfall infiltration causes the groundwater level of the slope body to rise, which may 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 drainage has the physical characteristics of being free of power and the flow process is automatically controlled by liquid level changes, which is very suitable for the needs of slope groundwater level control. The head of the siphon refers to the vertical height of the liquid in the siphon water pipe from the lowest po...

AI Technical Summary

Problems solved by technology

Manually starting the siphon has a large maintenance workload, and it is difficult to choose a reasonable time to start the siphon

[0007] The current low-lift siphon drainage system used in slope drainage generally starts the siphon drainage system when the groundwater level rises to a certain height, and the drainage lacks early warning capabilities
