Problems solved by technology

Existing rainwater abandonment wells or sedimentation wells are composed of multiple parts, which need to be combined and assembled during application. Not only is the operation inconvenient, but also there are gaps between the parts, and there is a problem of water leakage from the gaps when the rainwater is converging, especially in wet areas. When applied in subsidence loess areas, it will harm the road subgrade and cause subsidence

Embodiment Construction

[0036] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0037] As the first embodiment of the present invention, an integrated primary rainwater purification device is provided, such as figure 1 As shown, the device is arranged at the adjoining place between the hard pavement (ie hard pavement) and the sunken green space. A purification device can be set between two curbstones, or multiple purification devices can be spliced ​​together. figure 1 Three purification devices are spliced ​​in the middle, and in practical applications, a corresponding number of purification devices can be set according to the local rainfall. Such as Figure 2-6 As shown, the purification device includes: body 1, cover plate 2, water inlet 3, water outlet 4, slope protection plate 5, energy dissipation plate 6, handle 7, permeable hole 8, sedimentation area 9, slope protection block 10, gri...

Abstract

The invention relates to the field of initial rainwater purification, and provides an integrated initial rainwater purification device. The integrated initial rainwater purification device is arranged at the adjacent part of a hard road surface and a concave green land, and comprises: a body which is a square cavity formed by six surfaces comprising a first side face facing the concave green land, a second side face facing the hard road surface, a first end face and a second end face located at the two ends, a bottom face and a top face. a water inlet iwhich s formed in the second side face or the top face and used for guiding initial rainwater on the road surface into the body; a water outlet which is formed in the first side face, wherein the bottom of the water outlet is lower than the bottom of the water inlet, a preset distance is formed between the bottom of the water outlet and the bottom face, and a settling zone is formed in the lower portion of the cavity; and an energy dissipation plate which extends outwards from the bottom of the water outlet to form a gentle slope surface. Initial rainwater can be utilized, and the roadbed can be protected.

Description

technical field [0001] The invention relates to the field of initial rainwater purification, in particular to an integrated initial rainwater purification device. Background technique [0002] Initial rain refers to the initial rainfall of 4mm to 8mm. The quantity and quality of this part of water is relatively poor, and direct discharge will cause non-point source pollution and deteriorate the urban water environment. [0003] The existing measures to treat the initial rainwater mainly use rainwater abandonment wells or sedimentation wells. Most of the rainwater abandonment wells or sedimentation wells are set in the rainwater outlets, inspection wells or underground storage tanks. This kind of equipment has a large burial depth, a large area, a complex structure, and difficult installation. In order to install these rainwater abandonment Wells or sedimentation wells can only be connected to deeper storage facilities, which will cause certain restrictions and difficulties...
