Nylon mesh is used The bag replaces the fixed filter structure such as the traditional filter net. The material of the nylon mesh bag is relatively strong, and it can be moved freely. In this way, when debris accumulates in the nylon mesh bag, the nylon mesh bag will also swing due to the action of the water flow, so that Nylon mesh bags are not easy to block, and the surface area of nylon mesh bags is larger, which can accumulate more debris, which is convenient to reduce the number of cleaning, that is, effectively reduce the frequency of blockages, and more importantly, even if pedestrians accidentally step on the grille Fall into the sewer pipe 5, also can be caught by nylon net bag, prevents from being washed away by water, greatly improves the safety of road surface pedestrian.

When the rainfall is small, the accumulated water on the urban road surface will be discharged from the main drainage pipeline, and the auxiliary drainage pipeline will be in a sealed state, so that the auxiliary drainage pipeline will not be occupied. If the auxiliary drainage pipeline is not actively sealed, that is, no floating Balls, sealing baffles, etc., the water entering the sewer channel will also enter the auxiliary drainage pipeline due to surface fluctuations. When one drainage pipeline can drain the accumulated water on the ground, it takes up two drainage pipelines instead. , which is not conducive to the maintenance and maintenance of the auxiliary drainage pipeline. The utility model can avoid the occurrence of the above situation. Even if the flow of water entering the sewer channel fluctuates greatly, the auxiliary drainage pipeline will not be opened, which can reduce the auxiliary drainage. The number of times the pipeline is used, thereby reducing the number of dredging. At this time, the main drainage pipeline is more fully utilized for drainage; when encountering strong rainfall, the water inlet of the auxiliary drainage pipeline is opened, and a large amount of rainwater will pass through the auxiliary drainage. At this time, the main drainage pipeline and the auxiliary drainage pipeline drain at the same time, which can also improve the drainage efficiency of urban road rainwater.
