Description

Garden-style green roof rainwater storage and utilization system

technical field

The utility model relates to a roof storage and utilization system, in particular to a rainwater storage and utilization system suitable for garden-style green roofs.

Background technique

Most of the existing roof rainwater collection and utilization systems are to collect roof rainwater to the ground and then use it. In this way, many drainage devices need to be designed on the roof. As a new type of energy-saving and ecological roof, green roofs have been widely used all over the world, but As a densely planted roof form, the garden-style green roof has high requirements for irrigation and management, and requires frequent irrigation. If the roof rainwater can be collected locally for roof irrigation in non-rainy seasons, it can not only save drainage and irrigation costs, From a long-term perspective, it is the first choice for energy-saving and ecological building models.

Contents of the invention

In order to achieve the above purpose, the utility model provides a garden-style green roof rainwater storage and utilization system, which combines the green roof with rainwater storage and utilization, and fully collects and utilizes the roof rainwater on site.

The utility model is realized through the following technical solutions: a garden-style green roof rainwater collection and utilization system, plants are planted on the upper part of the roof, and a wall is made on the outer periphery of the roof; a water storage pool and a landscape water body are made on the roof ;A cover plate is provided on the upper part of the reservoir; an artificial matrix is made on the periphery of the reservoir and the cover plate; plants are planted on the top of the artificial substrate; ventilation hole; the reservoir is connected with an underground water collection pipe; water seepage holes are made radially on the pipe wall of the water collection pipe; geotextiles are made on the outer wall of the water collection pipe; Sand filter layer; the outside of the coarse sand filter layer is an artificial matrix; the upper part of the reservoir is communicated with the landscape water body through an overflow pipe; the bottom of the landscape water body and the reservoir are respectively provided with a waterproof layer; the waterproof layer The lower part is the bonding layer and the concrete structure layer in turn.

There are multiple water collecting pipes, which are evenly distributed on the periphery of the reservoir. The water collecting pipes have a longitudinal slope, and the smallest longitudinal slope is connected to the reservoir.

The overflow pipe has a longitudinal slope, the largest longitudinal slope is connected to the reservoir, and the smallest longitudinal slope is connected to the landscape water body.

There are multiple landscape water bodies, each of which is made of concrete pool walls and distributed at the four corners of the roof to connect with the walls.

The positive effect of the utility model is that the layout is reasonable, the reservoir can collect excess rainwater in the artificial matrix, and be used for roof irrigation in non-rainy seasons, and the rainwater exceeding the volume of the reservoir can be used to supplement the water in the landscape water body through the overflow pipe. Fully collect and utilize roof rainwater on site.
