Description

Be used for rainwater garden to store up engineering and plant roofing and prevent siphon system of arranging

Technical Field

The invention relates to the technical field of environmental engineering, in particular to an anti-siphon drainage system for a planting roof of a rainwater garden storage project.

Background

The rainwater garden is a naturally formed or artificially excavated shallow-recessed green land, and is used for gathering and absorbing rainwater from a roof or the ground, purifying the rainwater through the combined action of plants and sand, gradually infiltrating the rainwater into soil, conserving underground water, or supplementing urban water such as landscape water and toilet water. Is an ecologically sustainable rain flood control and rain water utilization facility.

The existing rainwater garden is low in height and is in a concave state, and vegetation is planted in concave cloth, so that rainwater can be converged conveniently. However, as rainwater erodes, the depth of the concave area is lower, and the soil on the surface layer is likely to be eroded completely, so that the rainwater infiltration speed is too high, the rainwater amount is too large, the siphon phenomenon is easily caused, and the erosion to the rainwater garden becomes more serious. And the vegetation is planted in the concave area, if the concave part is accumulated with water for a long time, the roots of the vegetation are soaked in the water, so that the problems that the roots of the vegetation are anoxic and rotten and the vegetation is dead are easily caused.
