Large storage amount water storing and draining plate for roof greening

Abstract

The invention relates to a large storage amount water storing and draining plate suitable for roof greening. The large storage amount water storing and draining plate comprises a plastic plate face, honeycomb water storing bottles, communicating grooves, draining holes, supporting columns, non-woven geotextiles and water absorbing belts. The plate face, the water storing bottles, the communicating grooves and the supporting columns are all made of high density polyethylene (HDPE) plastic base plates after stamping. The water storing bottles are arranged on the plate face in a honeycomb mode and connected through the communicating grooves. The water storing space is large, and meanwhile uniform water distributing is achieved. The draining holes are formed in the plate face. The supporting columns are arranged below the plate face. One layer of the non-woven geotextiles is adhered on the plate face and the bottom of the each bottle correspondingly. The water absorbing belts are arranged in the position, of the communicating grooves, of the geotextiles of the plate face and stretch in the bottoms of the bottles in the position of the water storing bottles. The structure is reasonable, forming is convenient, construction is convenient, maintenance is simple, the mechanical property is good, universality is high, system adaptability is strong, and meanwhile the multiple functions of water storing, water draining, filtering, ventilating, heat insulation, noise reduction, root thorns resisting and the like are achieved; and stored rainwater can be utilized to replenish water for a matrix.

Description

technical field

[0001] The invention belongs to the field of building greening engineering and relates to a roof greening storage and drainage board. Background technique

[0002] With the rapid development of urbanization, impermeable materials cover a vast urban area, resulting in urban heat island effect and urban waterlogging, and the contradiction between green land and urban construction land is increasingly intensified. In order to maximize the accumulation, infiltration and purification of rainwater in urban areas, the state and local governments have successively issued opinions and methods for the construction of "sponge cities" that promote the utilization of rainwater resources and ecological environment protection. The roof greening will transform the impermeable surface that occupies a considerable proportion of the city into a green space. While retaining rainwater, slow drainage and slow release, it will also play a role in energy saving, emission reduction, ...
