Description

Technical Field

[0001] The utility model relates to the technical field of ecological drainage ditches, in particular to a pollution intercepting device for lawn ecological drainage ditches. Background Art

[0002] At present, the existing drainage in the park is basically flat stone drainage on both sides of the road. The side flat stones with holes are often blocked by sludge, resulting in poor drainage. The existing technology usually uses ecological drainage ditches to solve this problem. The specific solution is to cover the ecological drainage ditch with grass, vegetation, and pebbles, and set up geotextiles and gravel layers in the ditch to play a certain purification role. Then, after a series of effects such as filtration, infiltration, sedimentation, plant absorption and biodegradation, it solves rainwater pollution and reduces the chance of sludge blockage and poor drainage in the park.

[0003] In recent years, as the test time of ecological drainage ditches has continued to increase, the applicant has found that in the rainy season, the ecological ditch is very convenient for rainwater discharge, and the rainwater can be smoothly discharged into the internal waters of the park through the drainage of the ecological ditch, and then the water for replenishment and maintenance of some waters is collected, achieving a sustainable green environmental protection effect. However, the ecological drainage ditch is not perfect. When the garbage on the road surface of the park (such as paper scraps, plastic bags, etc.) is washed into the ecological drainage ditch by rainwater, due to the lack of direct and effective pollution interception devices in the ecological drainage ditch, these garbage will be entangled in the plants or stones in the ecological drainage ditch, which will cause the water flow rate to slow down or even blockage, and ultimately reduce the drainage effect of the ecological drainage ditch.
