Description

Drainage system for garage roof

technical field

The utility model relates to rainwater collection and utilization, in particular to a drainage system for a garage roof.

Background technique

In order to meet the greening needs on the roof of the underground garage in the community, the roof of the underground garage needs to be waterproofed as a closed and impermeable system. Rainwater and irrigation water will accumulate on the roof through penetration. If there is no effective drainage and ventilation circulation system, the roof will accumulate for a long time. Water will cause the roof of the garage to leak to the underground garage and cause the roots of the plants to wither. Effective water storage and drainage facilities are installed on the roof of the garage, which can eliminate rainfall and irrigation water; store water to moisten the roots; filter sediment to prevent blocking the drainage pipeline.

At present, the water accumulated on the roof of the garage is drained directly into the municipal rainwater pipe network or discharged into the municipal rainwater pipe network after infiltration through the infiltration pond. This part of the drainage cannot be recycled in the community.

Utility model content

The purpose of the utility model is to provide a drainage system for the garage roof that can utilize the existing rainwater reuse system.

In order to achieve the above object, the utility model adopts the following technical solutions:

Drainage system for the garage roof, including the garage roof for water storage and the drainage water storage plate on the surface of the waterproof layer of the garage roof. The drainage water storage plate is connected to the drainage ditch on the side of the garage, and the drainage ditch is connected to the rainwater filtering device , The rainwater filter device is connected to the rainwater storage tank, rainwater or other water flows into the drainage ditch through the drainage storage plate, and finally flows to the rainwater storage tank for secondary use, and the water with more impurities flows into the rainwater municipal pipe network.

Further, the rainwater filtering device is a osmotic filter well, the shell outlet of the osmotic filter well is connected to the rainwater storage tank, and the clean water is introduced into the rainwater storage tank to realize secondary utilization, and the part with poor water quality flows into the rainwater Municipal pipe network.

Further, the structure of the garage roof from top to bottom is: planting soil, natural soil, irrigation system, geotextile, overhead grid, drainage and water storage board, waterproof layer, slope-making layer, planting soil and natural soil play a role Water storage function, the irrigation system is connected with the rainwater storage tank through pipelines, and is used for watering the vegetation on the roof of the garage.

Further, the drainage ditch is arranged on the outer edge of the roof of the garage to facilitate the inflow of rainwater.

Further, the drainage and storage plate is a plate with a plurality of grooves on its surface.

Further, the top of the drainage ditch is flush with the surface of the drainage storage plate.

The working principle of the utility model is: a layer of drainage water storage board is laid on the waterproof layer of the roof of the garage, which can store part of the rainwater infiltrated into the planting soil, and can also drain the excess water, which is beneficial to the growth of plants in the green belt of the roof of the garage. . Drainage and water storage board through slope finding, the excess water is discharged into the roof gutter of the garage. The water collected in this part contains sediment, and the water quality is poor (including plant fertilizers), so it cannot be directly introduced into the rainwater storage tank. The collected water is precipitated and infiltrated through the osmotic rainwater filtration device, and the excess cleaner water It flows into the rainwater storage tank and is used as rainwater recycling water for reuse after treatment.

The beneficial effects of the utility model are:

1. Reasonable and simple structure, convenient assembly and maintenance-free.

2. Using the existing drainage and rainwater reuse facilities, the technology is mature and easy to realize.

3. After the collected garage roof drainage is settled and filtered by the permeation filter well, the cleaner water flows into the rainwater storage tank as a water source for greening, realizing the recycling of greening water and drainage, and reducing the drainage of the municipal pipe network.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

The drainage system for the garage roof includes the garage roof used for water storage and the drainage water storage plate 1 arranged on the surface of the waterproof layer of the garage roof. The drainage can be collected and discharged uniformly. The drainage ditch 2 is arranged on the outer edge of the roof of the garage to facilitate the inflow of rainwater. The top of the drainage ditch 2 is flush with the surface of the drainage storage plate 1 . The bottom of the drainage ditch 2 is connected to the rainwater filtering device 3, and the rainwater filtering device 3 is connected to the rainwater storage tank 4. Rainwater or other water flows into the drainage ditch through the drainage storage plate 1, and finally flows to the rainwater storage tank 4 for secondary utilization , the water with more impurities flows into the rainwater municipal pipe network.

The rainwater filtering device 3 is a osmotic filter well, and the rainwater filtering device 3 introduces clean water into the rainwater storage tank 4 to realize secondary utilization, and the part with poor water quality flows into the rainwater municipal pipe network.

The structure of the garage roof from top to bottom is: planting soil, natural soil, irrigation system, geotextile, overhead grid, drainage and water storage board 1, waterproof layer, slope-making layer, planting soil and natural soil play a role in water storage Function, the watering system is connected with the rainwater storage tank 4 through pipelines, and is used for watering the vegetation on the roof of the garage.

The drainage water storage plate 1 is a plate provided with a plurality of grooves on the surface.

On the waterproof layer of the garage roof, a layer of drainage water storage board 1 is laid, which can store part of the rainwater infiltrated into the planting soil, and also drain excess water, which is beneficial to the growth of plants in the green belt of the garage roof. The excess water is discharged into the garage roof gutter 2 through slope finding in the drainage water storage plate 1 . The water collected in this part contains sediment, and the water quality is poor (including plant fertilizer), so it cannot be directly introduced into the rainwater storage tank 4, and the collected water is precipitated and infiltrated through the osmotic rainwater filter device, and the excess is relatively clean The water flowing into the rainwater storage tank 4 is used as rainwater recycling water for reuse after treatment.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
