Background
The siphon drainage technology abandons the traditional drainage method of the broken stone (pebble) of the planting roof, and the seepage water in the soil of the planting area is drained to the water collecting well through the drainage special-shaped sheet and the siphon drainage groove, so that the organized zero-gradient drainage of the water stagnation of the planting roof is realized, and the purposes of drainage, water collection and secondary collection and utilization of rainwater resources are achieved.
For the related art, the siphon drainage technology relies on the change of pipe fittings to change the pressure change in the drainage pipeline, so that full pipe flow is formed, the atmospheric pressure difference is formed at the two ends of the full pipe, and when the water flow quality of the vertical section is greater than that of the horizontal section, the water flow speed can be increased, so that the water flow can automatically approach to the drainage port under the condition of not finding a slope.
However, even though the flow rate of the water in the horizontal pipe section is slow, because of the nature of the water body, when the water volume is enough to form a water body film covering the whole plane on the plane, the water body still expands towards any direction, the expansion is constrained by the tension of the water body, namely, when the tension of the water body is insufficient to constrain the weight of the water body, the water body expands, and when the water is applied to the horizontal pipe of the siphon drainage technology, when the water flow direction is insufficient to enable the horizontal pipe section to form a full flow pipe, the siphon drainage technology is not established, even though the flow rate in the horizontal pipe is slow, when the water body completely covers the surface of the horizontal pipe, the water body film covers the junction of the horizontal pipe and the vertical pipe, the boundary tension of the water body film cannot constrain the weight of the water body, the boundary of the water body film expands outwards, so that the boundary of the water body enters the vertical pipe section, and the boundary of the water body film is destroyed, and then the water body flows towards the vertical pipe section because of the molecular force of the water body is mutually pulled towards the vertical pipe instead of piling up in the horizontal pipe, no matter how slow the flow rate of the water flow in the horizontal pipe is formed in the horizontal pipe, if the vertical pipe section cannot form a full flow pipe section, the full flow pipe in the horizontal pipe section is formed, and the vertical pipe section is difficult, and the vacuum condition is obtained. Even in such a case, in an area where the variation of the rainfall is relatively large, if the pipe diameter of the vertical pipe section is contracted for the case where the rainfall is small, the drainage capacity of the drainage system is insufficient to cope with a large amount of rainfall in the case of sudden heavy rain; if the pipe diameter of the vertical pipe section is kept under the condition of large rainfall, all pipe sections can not form full flow pipes when the rainfall is small, and the drainage efficiency is low.
