A drainage device for multi-layer environment-friendly permeable floor

Abstract

The invention relates to the technical field of floor drainage, and discloses a drainage device for a multi-layer environment-friendly permeable floor, including a ground surface, the upper end of the ground surface is fixedly connected with a planting frame to the left, the inside of the planting frame is filled with soil, and the upper end of the ground surface A rectangular groove is provided, a baffle plate is fixedly connected to the upper end inside the ground surface, a square hole is arranged at the lower end of the baffle plate, a fixed cylinder is fixedly inserted in the middle of the upper end of the baffle plate, and a pressure plate is movably socketed on the outside of the fixed cylinder. After each rain, the rainwater flows through the floor layer to the upper end of the filter layer. The rainwater is filtered under the action of the filter layer and then flows to the upper end of the baffle through the leak hole, and then the rainwater flows to the interior of the ground through the square hole for storage. The height of the rainwater inside the surface reaches the opening at the right end of the drain. At this time, the excess rainwater inside the surface is discharged through the drain, so as to effectively absorb road rainwater, effectively replenish groundwater, maintain the balance of the urban natural water system, and reduce the risk of urban waterlogging. Effect.

Description

technical field [0001] The invention relates to the technical field of floor drainage, in particular to a drainage device for multi-layer environment-friendly permeable floors. Background technique [0002] As a new environmentally friendly and ecological road material, permeable floor has attracted increasing attention from people, especially the industry. The surface of modern cities is mostly covered by reinforced concrete buildings and impermeable roads, which are in harmony with natural soil. Compared with ordinary concrete pavement, which lacks the ability to breathe, absorb heat and infiltrate rainwater, it brings a series of environmental problems, and concrete has always been considered the culprit of destroying nature, but as long as continuous voids can be formed, it can Create a connection point with the natural environment. [0003] The existing permeable floor drainage equipment does not have the function of storing water. Whenever it rains, because the permea...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a drainage device for multi-layer environment-friendly permeable floors, which can effectively absorb road rainwater, effectively replenish groundwater, maintain the balance of urban natural water systems, reduce the risk of urban waterlogging, and be able to The rainwater is stored for irrigating flowers and plants, reducing the maintenance cost of green plants and other advantages, and solves the problem that ordinary floor drainage equipment cannot effectively absorb road rainwater, do not have the function of replenishing groundwater, cannot maintain the balance of urban natural water systems, and exist in cities. The risk of waterlogging, the inability to store rainwater for irrigation of flowers and plants, and the inability to reduce the cost of green plant maintenance
