Description

roof drainage system

technical field

The invention relates to the technical field of building drainage, in particular to a roof drainage system.

Background technique

In recent years, due to the increase in rainstorms due to abnormal climate changes, floods have occurred in many cities in our country, seriously endangering the safety of people's lives and property. Therefore, the country is vigorously promoting the application of sponge city technology. In the sponge city technology, a landmark technology is the application of green roof drainage system. The conventional method is to build a concrete gutter on the roof, and connect the side of the soil through the pre-buried drainage pipe at the bottom of the gutter to guide the accumulated water to The gutter is discharged through the drainage system.

Due to the characteristics of the green roof, it usually lacks a filtration system. The water discharged from the embedded drain pipe at the bottom of the gutter will inevitably be accompanied by a lot of soil and other impurities, which will easily cause the drain pipe to be blocked. Once the drainage pipe is blocked, the accumulated water will not be able to enter the side of the gutter, and the soil and vegetation will have to be soaked in water, which will adversely affect the ecosystem in the soil and the survival of vegetation. In addition, the rainwater entering the gutter will inevitably contain more impurities, which will easily cause blockage of the drainage device (usually a rain bucket) in the gutter and downstream drainage pipes, endangering the safety of roof drainage. At the same time, when the pre-buried drainage pipe is blocked, it is necessary to detect the location of the blockage point by point to find the blockage point, and then dig the gutter to clear the pipe, which will consume a lot of manpower and material resources.

Contents of the invention

Based on this, it is necessary for the present invention to provide a roof drainage system that can prevent soil and other impurities from flowing into drainpipes and drainage devices together with rainwater to cause blockage, ensure the survival of ecosystems and vegetation in the soil, and the safety of roof drainage, while removing blockages and maintenance The method is simple and saves manpower and material resources.

Its technical scheme is as follows:

A roof drainage system comprising:

a roof, the roof being provided with drainage channels;

A first enclosure body, the first enclosure body is arranged at intervals on one side of the drainage channel, and the first enclosure body is provided with at least one first seepage and drainage part;

The second enclosure body, the second enclosure body is arranged at intervals on the side of the drainage channel away from the first enclosure body, and the second enclosure body is provided with at least one second seepage and drainage part, The cooperation between the first enclosure body and the second enclosure body forms a water collection cavity communicating with the drainage channel, and both the first seepage drainage part and the second seepage drainage part are connected to the sink Water cavity connected;

A first water-permeable filter body, the first water-permeable filter body is arranged on the roof and is located on the side of the first enclosure body away from the water collection cavity;

A second water-permeable filter body, the second water-permeable filter body is arranged on the roof and is located on the side of the second enclosure body away from the water collection chamber; and

A soil-covering body, the soil-covering body surrounds the first water-permeable filter body and the second water-permeable filter body on a side away from the water collection cavity.

The above-mentioned roof drainage system forms the first enclosure body and the second enclosure body by stacking on both sides of the drainage channel respectively, and makes the first seepage drainage part and the second seepage drainage part communicate with the water collection cavity and the drainage channel; after that Set the first water-permeable filter body on the side of the first enclosure body away from the water collection chamber, arrange the second water-permeable filter body on the side of the second enclosure body away from the water collection chamber, and finally place the covering soil on the first water-permeable body The outside of the filter body and the second water-permeable filter body. In this way, in rainy days, the rainwater first infiltrates into the covering soil, and then through the filtration and infiltration of the first water-permeable filter body and the second water-permeable filter body, the soil and other impurities mixed in the rainwater can be well filtered out; After the second filtration of the rainwater through the first infiltration part and the second infiltration part, the soil and impurities contained inside can be further removed, so that the relatively clean rainwater flows into the water collection cavity and then is discharged into the drainage channel, thereby avoiding drainage If the channel is blocked, ensure that too much rainwater will not accumulate in the covering soil, ensure the survival of the ecosystem and vegetation in the soil, and the safety of roof drainage; in addition, even if a blockage occurs, it can be dredged by using high-pressure water flow for all-round backwashing For the blocked part, the method of removing and repairing the blockage is simple, saving manpower and material resources.
