Description

A side-discharge urban road water drainage and stagnation device

technical field

The invention belongs to the field of urban drainage equipment, and in particular relates to a side-discharge type urban road water drainage and stagnation device.

Background technique

In recent years, heavy rain often causes urban roads to be flooded. The country vigorously advocates the construction of sponge cities. To build a sponge city, it is necessary to play the role of absorbing and storing rainwater in every area that has not been hardened by concrete, and play the role of flood drainage and regulation together with urban rivers and waterways. However, the green belts in the middle or both sides of the existing urban roads are generally higher than the road surface, which can only beautify and purify the air to a certain extent, but do not have the functions of collecting rainwater and removing road water. Commonly, a certain number of rainwater drainage outlets are set on both sides of the road surface, and the rainwater grates are covered on the top. The rainwater collected by the drainage outlets enters the municipal pipe network and is discharged into nearby rivers or lakes.

The advantage of this design is clear responsibility and convenient maintenance and management, but the disadvantages are also obvious. First, the falling water grate flush with the road surface is easy to be blocked by fallen leaves and garbage, and it is easy to cause water on the road to affect traffic during heavy wind and rain. Second, the tire wear powder and dust accumulated on urban roads are washed by rainwater and enter the municipal pipe network to be discharged into rivers or lakes, thereby polluting urban rivers or lakes. Thirdly, all the pipe networks are designed to drain water as quickly as possible, rainwater cannot be stored and utilized, and green belts need to be watered from tap water, which also causes a waste of water resources.

Contents of the invention

The purpose of the present invention is to provide a side drainage urban road water drainage and stagnation device that prevents clogging, is easy to maintain, has high drainage efficiency, can store and filter road rainwater and then use it for irrigation and greening, and saves water resources.

The technical solution adopted by the present invention to achieve the above object is: a side-discharge type urban road water drainage and stagnation device, including a water collection box for storing water, the water collection box is arranged at intervals along the direction of the greening long side belt, and the water collection box Located below the green belt structure; the green belt structure consists of a growth medium layer, a filter grid, and a filter water storage layer from top to bottom. One side of the green belt structure is connected to the curb, and multiple water inlet pipes are arranged side by side inside the curb , the inlet of the water inlet pipe is flush with the road surface. The level of the road surface and the inlet can make the accumulated water enter the device quickly. At the same time, multiple water inlet pipes are arranged side by side, which speeds up the discharge of the road surface water, improves the drainage efficiency, and indirectly ensures the traffic condition of the road surface. The structure of the green belt is divided into Three layers, the green belt structure has good water storage, water absorption, and filtering functions. The rainwater absorbed by the growth medium layer can directly provide the plants with the required water, ensuring the normal growth of green belt plants. The filter grid can collect Filter the water to a certain extent, so that the filtered water enters the filtered water storage layer for storage, and is used for watering plants when there is no rain for a long time and the plants are dry, which is conducive to saving water resources. This device has a simple structure, convenient maintenance, and good drainage effect , conducive to market promotion.
