Abstract
The invention provides a self-starting type side slope siphoning drainage system. When a siphoning drainage method is used, in the dry season with little rainfall, the underwater water level is lowered, no water on a slope body needs to be drained through the siphoning effect, the siphoning drainage system is in an inoperation state, air dissolved in water can be separated out in a bubble form and is accumulated in a siphon continuously, the vacuum degree in the siphon is lowered, and thus the problem that siphoning is difficult to start again or even the siphonage disappears is caused. The system is composed of a vertical type dyke, an air chamber, the siphon, an exhaust pipe, a blowdown pipe and check valves. The air chamber is arranged at the top of the vertical type dyke. One end of the siphon extends into the position below the underwater water level of a side slope, and the other end of the siphon penetrates through the air chamber and extends into the position below the sea level. One end of the exhaust pipe extends to the position below the underground water level of the rear edge of the side slope, and the other end of the exhaust pipe is connected with the air chamber. The blowdown pipe is arranged at the upper end of the air chamber. The exhaust pipe and the blowdown pipe are both internally provided with the check valves.
