Novel rainwater flow guiding device for municipal administration roads

Abstract

The invention relates to the field of draining of municipal administration roads and particularly relates to a novel rainwater flow guiding device for municipal administration roads. The novel rainwater flow guiding device comprises a foundation pit formed in a draining region, wherein impounding reservoirs are arranged on two sides of the foundation pit, and a planting layer and a macadam layer are arranged between the impounding reservoirs on two sides; water inlets are formed in the top ends of the impounding reservoirs, and draining pipelines are connected to the side walls of the middle sections of the impounding reservoirs; and a water storage tank is arranged in the macadam layer and is communicated with the impounding reservoirs on two sides through water through pipelines, and a plurality of water absorbing cotton strips which penetrate through a tank body and extend into the planting layer are arranged in the water storage tank. The water storage tank is separated from the impounding reservoirs, the planting layer is separated from the macadam layer, and the water absorbing cotton strips are used for conveying moisture, so that the waterlogging death of the plants causedby serious impoundment is prevented; and during the inundation of rainwater, water can be drained by virtue of the drainage pipeline, so that the water levels in the impounding reservoirs and the water storage tank are controlled.

Description

technical field [0001] The invention relates to the field of municipal road drainage, in particular to a novel municipal road rainwater diversion device. Background technique [0002] At present, the Chinese patent document with the authorized announcement number CN204741963U in the prior art discloses a rain garden for the green belt in the middle of the road. When water is formed on the road surface, the water on the road surface can be drained into the gravel layer in the rain garden through the drainage holes on the curb; a breathable and anti-seepage sand layer is added to the bottom of the rain garden to prevent plant rot, At the same time, it can also prevent the rainwater entering the rain garden from seeping into the ground. A water-blocking layer is set on the contact surface between the planting layer, nutrient soil layer and gravel layer and the inner wall of the foundation pit, so that the rainwater entering the rain garden is stored in the rainwater In the gar...

Problems solved by technology

[0003] However, when rainwater floods, because the air-permeable and anti-seepage sand layer hinders the rainwater from continuing to infiltrate downwards, the rainwater in the rain garden continues to rise. They are discharged one after another, resulting in insufficient oxygen in the roots of the plants, difficulty in breathing in the roots, and the production of toxic and harmful substances such as ethanol, which affects plant growth and even causes plant death
