Technical Field

The utility model relates to sump pit technical field especially relates to a be equipped with and cut infiltration sump pit of dirty net.

Background

At present, rainwater usually directly permeates a ceramsite layer, a planting soil layer and a gravel layer and then slips away from a drainage pipe. The rainwater treatment method has the advantages that in the biological detention pond, the landscaping effect is mostly unsatisfactory due to improper plant matching or survival problems, the integral aesthetic effect is influenced, and the integral aesthetic effect and the landscape effect are not in a good condition. Particularly, in some selected planting soil layers with improper permeability coefficients or biological detention ponds which are not replaced and filled for a long time, the permeability coefficient is small, when the rainfall is large or the rainfall is frequent, accumulated water in the facility cannot permeate for a while, and the rainwater is discharged from the overflow port without being treated. The to-be-solved problem of the utility model is that the area of the rainwater garden that needs handling the same rainfall reduces, alleviates because of improper or survival etc. of plant collocation makes the problem that the scene effect is not as good as possible, solves the problem how to handle more rainwater simultaneously.

The utility model discloses a be equipped with infiltration sump pit of intercepting dirty net, this be equipped with infiltration sump pit of intercepting dirty net get into biological detention pond when the rainwater, the rainwater is from the haydite layer, plant the soil layer, the gravel layer is through the drain pipe discharge, it is big when the rainfall, then there is certain water-retaining layer in the biological detention pond, reach certain water level rainwater and just get into HDPE infiltration sump pit from the inlet opening of HDPE apron, HDPE infiltration sump pit all around and the bottom all cloth have the infiltration hole make things convenient for the rainwater to permeate to plant soil layer and gravel layer, carry out the rainwater and handle, infiltration sump pit top is less than the overflow mouth, reach the overflow mouth when the rainwater and just discharge from the overflow mouth, the event is permeable and is handled more rainwater. Cut dirty net and can filter the suspended particles thing of rainwater, the geotechnological cloth layer that permeates water in the HDPE infiltration sump pit outside can effectively prevent the infiltration hole when permeating water and block up. The utility model has strong rainwater purification capability of the infiltration water collecting well provided with the sewage interception net, and simultaneously improves the view of the bioretention pond; not only can treat more rainwater, but also can ensure the effect of rainwater treatment and purification. The infiltration water collecting well has the advantages of strong integral structure, simple principle, simple structure and convenient installation; is especially suitable for areas with large rainfall and high rainfall frequency or for bioretention ponds with packing layers with poor permeability coefficients.

SUMMERY OF THE UTILITY MODEL
