Technical Field
The invention relates to the technical field of side slope drainage, in particular to a side slope internal automatic drainage structure based on rainfall
Background
The rainfall infiltration causes the underground water level of the side slope to rise, and landslide disasters are easily induced. The underground water in the slope is discharged in time, the underground water level in the slope is controlled below a safe water level surface, and the method has important significance for preventing landslide disasters. The siphon is a physical phenomenon that liquid is pushed to flow by the action force of the height difference of the liquid level, the flowing process and the flow rate of the siphon are automatically controlled by the change of the liquid level, and the physical characteristics very accord with the requirement of slope drainage and are suitable for popularization and application in slope drainage.
The siphon is filled with air in the initial state, the siphon needs to be filled with water under the action of external force when being started, and the top of the siphon forms a negative pressure environment under the action of the gravity of liquid in the sewer pipe so that the water in the upper water pipe of the siphon rises under the action of pressure difference to form siphon. Therefore, the siphon starting process is to remove the original air in the siphon pipe and fill the pipe with water. Common siphon start methods are: pumping water from the water outlet, reversely pressing the water outlet, reversely irrigating and the like. In order to fill the siphon with water, the most direct way is to install a water pumping device at the water outlet and start the siphon by pumping water, such as a vacuum pump, a high-pressure manual pump and the like. Because slope siphon drainage process has characteristics such as intermittent type nature, slow mobility and high lift, can be in siphon process and the long-time in-process that stops flowing air that the intraductal air accumulation can lead to the siphon to be interrupted. If the groundwater in the slope is low, energy and water resource waste can be caused by frequently pumping water to start siphoning, and if the groundwater in the slope is high, but the siphoning is not started in time, landslide disasters can be induced.
