A vehicle resistance device capable of pre-treating rainwater and a system combined with the vehicle resistance device

Abstract

The invention discloses a vehicle resistance device capable of pretreating rainwater, which comprises a vehicle resistance body and a well pit, the vehicle resistance body is sealed at the mouth of the well pit, and a water inlet hole is opened on the bottom side wall of the vehicle resistance body. In the middle of the well pit, there is a partition with a leaking hole to separate the upper well pit and the lower well pit; in the lower well pit, there is a rainwater collection tank on the outside of the discarded running water and sand channel; the partition wall on one side of the rainwater collection tank is provided with a through hole, which connects the rainwater Storage Room. It also discloses a system combined with the vehicle resistance device, which consists of a plurality of vehicle resistance devices arranged along the road at a certain distance, and the discarded water and sand channels of the upper and lower two vehicle resistance devices are connected with the discarded outflow water pipe. The rainwater storage room of the resistance device is connected to the sandstone cushion at the bottom of the green landscape plant of the next vehicle resistance device through the rainwater outlet pipe. The invention solves the problems of large occupied area of ​​rainwater treatment facilities and reuse, preliminary treatment of rainwater, reduction of urban waterlogging and the like.

Description

technical field [0001] The invention belongs to a rainwater treatment and collection device, in particular to a vehicle resistance device capable of pretreating rainwater and a system combined with the vehicle resistance device. Background technique [0002] Vehicle blocking stones are installed at the entrance of roads and squares to prevent vehicles from entering the no-go area. Since there is no vehicle on the ground and the load is small, it has potential for the transformation and utilization of the underground space in the no-go area. [0003] With the acceleration of China's urbanization process, the increase of urban hard roads and squares has led to increasingly prominent problems of urban waterlogging and non-point source pollution. The surface runoff of urban roads and squares is large and there are different degrees of pollution, which poses a serious threat to the urban water system. At present, controlling non-point source pollution has become the key directio...
