Vehicle resisting devices capable of pretreating rainwater and system combined by same

Abstract

The invention discloses vehicle resisting devices capable of pretreating rainwater. Each vehicle resisting device comprises a vehicle resisting body and a well pit, wherein the vehicle resisting body covers the opening portion of the well pit. Water inlet holes are formed in the side wall of the bottom of each vehicle resisting body. A partition plate with a water leaking hole is arranged in the middle of each well pit and divides the well pit into an upper well pit body and a lower well pit body. In each lower well pit body, a rainwater collecting tank is arranged on the outer side of an abandoned flow water-sand channel. A through hole is formed in a partition wall on one side of each rainwater collecting groove. Each through hole communicates with a rainwater storage chamber. The invention further discloses a system combined by the vehicle resisting devices. The system is formed by arranging of the multiple vehicle resisting devices at certain distances along a road. The abandoned flow water-sand channels of each upper resisting device and the corresponding lower vehicle resisting device are connected through an abandoned flow water outlet pipe, and the rainwater storage chamber of each last vehicle resisting device is connected with a sandstone cushion layer of the bottom of a green landscape plant of the next corresponding vehicle resisting device through a rainwater collecting water outlet pipe. The problems of the large occupied area and recycling of a rainwater treatment facility, rainwater preliminary treating, reducing of urban waterlogging and the like are solved.

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...
