Rainwater penetrating-discharging integrated ecological system

Abstract

The invention discloses a rainwater penetrating-discharging integrated ecological system, which comprises penetration inspection wells distributed on the ground of residential areas, penetration drainage ditches which are in a network shape and connected on all the penetration inspection wells and transversal connecting pipes between the penetration inspection wells and the penetration drainage ditches. Permeable holes are formed on the side walls and at the bottoms of the penetration inspection wells, a gravel layer is laid in the peripheries of the penetration inspection wells, a layer of permeable geotextile is laid in the peripheries of the gravel layer, wellheads of the penetration inspection wells are provided with dirt-catching and sewage-blocking baskets therein and permeable well covers are covered on the wellheads; permeable holes are formed on the side walls of the penetration drainage ditches, the peripheries of the penetration drainage ditches are provided with the gravel layer, the peripheries of the gravel layers are provided with a layer of permeable geotexile, and the top parts of the penetration drainage ditches are covered with grate covers of the drainage ditches. The invention has the advantages of simple design principle and convenient construction. The invention can save water consumption, reduce rainwater runoff in a city and relieve municipal drainage pressure, thereby not only realizing early draining of rainwater, purifying water, but also realizing the penetration of rainwater, conserving underground water source and beautifying the peripheral ecological environment.

Description

technical field [0001] The invention relates to a system for utilizing rainwater resources, in particular to a system for utilizing rainwater resources in building quarters. Background technique [0002] In cities, rainwater falling on the ground or roofs is directly discharged to the municipal drainage pipe network through the rainwater grates on the ground or the gutters on the ground, which increases the runoff of rainwater in the city and increases the drainage pressure of the municipal pipe network. Especially in today's large-scale demolition and reconstruction of cities and the construction climax of a large number of new residential areas, many new residential areas need to lay deep-buried rainwater pipes and connect them with the existing municipal drainage network, which increases the existing municipal drainage network. load. On the other hand, because most of the rainwater fails to return to the ground, the groundwater level in the city has been greatly reduced ...
