Siphon drainage collection is capable of systematically draining excess water from a drainage plate through a siphon drainage trough to a catchwater well and reusing the collected water in the catchwater well. It breaks the criticism that rainwater collection can only collect surface water and infiltration water in some areas, and collects all surface water and infiltration water to make full use of precious natural resources. Moreover, roof water level can be kept at a low level to maintain the air permeability and water permeability of soil and ensure the normal growth of plant roots. And can be used as a waterproof layer of flexible protection layer, replace the cement protection layer, great engineering cost. Siphon drainage collection is especially suitable for the areas where the roof area is large and the discharge slope is difficult.A brief introduction to the long-acting covering drainage boardLong - acting cloth drainage plate, high tensile filter plate. Strong tensile strength, the drainage plate and cloth hot melt forming, also known as the water drainage plate, drainage plate and geotextile integration. Both the raised height and the weight of the cloth can be customized.The characteristics of long - acting covering cloth drain plate1, integrated hot melt integration process, can reduce the construction process, paved, laid can be immediately covered with soil2, integrated hot melt integration process, per square meter of more than 1000 convex point support, super soil carrying capacity, to ensure that the overburden does not collapse, ensure the drainage system smooth.3. Integrated hot-melt integration technology, super pressure resistance and soil carrying capacity, can permanently maintain the gap between the press cloth and the drainage channel, so as to achieve root blocking effect and ensure that the waterproof layer will not be destroyed. Reduced building load.Siphon drainage plate cover cloth technology is good, so better than the ordinary geotextiles filter sediment. When used, "because the filter is good, so the platoon is good; Because the platoon is good, so guard well." Through the realization of active drainage, the waterproofing effect of the system is ensured.
