Cleanable water-permeable hollow kerb for receiving runoff

Abstract

The invention discloses a cleanable water-permeable hollow kerb for receiving runoff. The kerb comprises a bottom wall 1, a left wall 3, a right wall 4, a front wall 5 and a rear wall 6, a convex block 7 is arranged on the inner surface of the upper parts of the front wall and the rear wall, a top wall 2 and the convex block are movably connected, the bottom wall, the left wall, the right wall, the top wall, the lower part of the front wall and the upper part of the rear wall are separately prepared from concrete, the upper part of the front wall is prepared from a material with a water-permeable function, and the lower part of the rear wall is prepared from a material with a water seepage function. Compared with a traditional kerb, the cleanable water-permeable hollow kerb for receiving the runoff provided by the invention can effectively absorb runoff rainwater formed by a road, avoid water accumulation of the road, slow down urban flood disasters, can supplement groundwater resources, provide moisture for green plants grown on two sides of the road, and reduce maintenance costs; and meanwhile a flushable structure is designed, so that backwashing of a high-pressure water gun canbe facilitated, the service life of the kerb can be prolonged, and the costs are reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a roadside building accessory capable of collecting and absorbing runoff rainwater from a highway, and in particular to a cleanable and permeable curbstone carrying runoff. technical background [0002] Curbstone is a kind of road edge building accessory that is often used in the road construction process. It is generally used as a strip stone set on the edge of the road surface and separated from other structural belts. It can also stabilize the roadbed and maintain driving safety. It is widely used in road construction process. However, while the traditional curb divides the area, it hinders the normal drainage of the road and leads to serious water accumulation on the road. Especially in rainy weather in the south or concentrated rainfall in the north, it is very easy to cause water accumulation on the road in rainy days, which affects driving safety. With the incre...

AI Technical Summary

Problems solved by technology

However, while the traditional curb stone divides the area, it hinders the normal drainage of the road, resulting in serious water accumulation on the road, especially in rainy weather in the south or concentrated rainfall in the north, which can easily cause water accumulation on the road in rainy days and affect driving safety.

With the increase of urban hardened ground, rainfall is directly discharged into the drainage pipe network, which cannot effectively replenish groundwater, and urban green spaces also need special watering and irrigation

Not only can urban water resources not be fully utilized, resulting in a large waste of rainwater, but also need to extract groundwater resources to irrigate plants, increasing maintenance costs, reducing groundwater levels, causing great waste and environmental problems
