Description

Novel two cabin rainwater side wells

Technical Field

The utility model belongs to the technical field of the technique of initial stage rainwater and specifically relates to a can handle novel two cabin rainwater limit wells of initial stage rainwater.

Background

Along with the continuous improvement and updating of urban construction and municipal infrastructure in China, the number of rainwater side wells paved along municipal roads is continuously increased. The rainwater side well is a structure for collecting rainwater on a rainwater pipe duct or a confluence pipe duct. Rainwater on the street surface firstly flows into the drainage pipe channel through the rainwater side well through the connecting pipe. The form, the number and the arrangement of the rainwater side wells are determined according to the quantity of the produced catchment areas, the drainage capacity of the rainwater side wells and the form of the road. The rainwater side well can be arranged at a position which can ensure that the ground rainwater can be collected quickly and effectively.

The existing municipal road rainwater side well mostly adopts a single-cabin type rainwater side well, rainwater collected on a road surface and sundries (dead branches, leaves, silt and the like) washed away by the rainwater are discharged into a rainwater pipeline through the rainwater side well.

The above prior art solutions have the following drawbacks:

1. the rainwater side well is easy to block, and water accumulation phenomenon can easily occur on the road sections with the blocks when the road sections are in rainy days, particularly when rainwater is large.

2. Municipal road is one of the main places that the pollutant produced, and there are a large amount of pollutants such as pitch, oil, rubber on the road surface, and the washing away pollutant through the rainwater just enters into municipal pipe network by the rainwater side well, has increased the burden for rainwater treatment facility, and partial rainwater directly discharges the river course simultaneously, pollutes the water, worsens quality of water.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel two cabin rainwater limit wells, it can filter the debris that contain in the initial stage rainwater, carries out the preliminary treatment to the pollutant in the initial stage rainwater simultaneously to avoid untreated rainwater directly to discharge into and river course pollution water quality.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a novel double-cabin rainwater side well comprises a dredging ditch and a drainage ditch, wherein a municipal rainwater branch pipe is arranged on a side wall body of the drainage ditch, a cover plate is arranged at the top end of the wall body of the drainage ditch, and an overflow port is formed in the wall body between the dredging ditch and the drainage ditch and above the municipal rainwater branch pipe; the top end of the dredging ditch is provided with a rainwater side well grate seat, and a rainwater grate is placed on the rainwater side well grate seat; and a purification block is arranged at the bottom of the dredging ditch.

By adopting the technical scheme, rainwater flows into the dredging ditch through the rainwater grate in rainy days, and sundries such as dead branches, leaves, silt and the like flow into the dredging ditch along with the rainwater; pollutants such as asphalt, oil, rubber and the like on the surface of the road are washed away by rainwater, the pollutants flow into the dredging ditch along with the rainwater, and the purifying block at the bottom of the dredging ditch can preliminarily treat the pollutants in the rainwater and purify the rainwater; after the dredging ditch is filled with rainwater, the rainwater flows into the drainage ditch from the overflow port and then enters the municipal pipe network through the municipal rainwater branch pipe; therefore, the effect of preventing the rainwater side well from being blocked is achieved, and the effects of pretreating rainwater and reducing the burden of rainwater treatment facilities are also achieved;

the apron can make things convenient for the laying of flat stone, falls into the escape canal when avoiding laying.

Furthermore, a blocking filter screen is detachably arranged in the dredging ditch and above the overflow port.

Through adopting above-mentioned technical scheme, block the debris that the thing filter screen can the prefilter rainwater, can play the effect of holding back in aquatic debris suspended solid, reduce indexes such as SS of rainwater to avoid municipal administration rainwater branch pipe to block up, alleviate rainwater processing apparatus's burden.

Further, the top of purifying the piece is provided with the filth and collects the net, the removable setting in the desilting ditch of filth collection net.

Through adopting above-mentioned technical scheme, the staff can collect the net with the filth and pull down after the rainy day, takes out the clearance from the desilting ditch to play and make things convenient for the staff to clear up rainwater side well effect.

Further, the dirt is collected and is fixed on the net and be provided with the chain, the one end of chain is fixed on the dirt is collected on the net, the other end of chain is fixed at the top of desilting ditch inside wall, the dirt is collected the net and is fixed to be placed on purifying block through self gravity.

Through adopting above-mentioned technical scheme, the staff is through carrying the chain, and then collects the filth and net and take out the clearance, and the rethread chain collects the filth and nets and put into the desilting ditch after the clearance finishes to play and make things convenient for the staff to get the effect that the filth collected the net, and then play and make things convenient for the staff to clear up rainwater side well effect.

Furthermore, an activated carbon layer is laid at the upper end of the dirt collecting net.

By adopting the technical scheme, the activated carbon can further clean the particle impurities in the water, and the burden of the rainwater treatment device is reduced.

Furthermore, the upper surface and the lower surface of the activated carbon layer are provided with geotextile filter screens, and the activated carbon layer is wrapped by the geotextile filter screens.

Through adopting above-mentioned technical scheme, the geotechnological cloth filter screen can prevent that the active carbon layer from scattering, and geotechnological cloth filter screen also can play the filtering action simultaneously, alleviates rainwater processing apparatus's burden.

Furthermore, a filter screen is arranged at the overflow opening.

Through adopting above-mentioned technical scheme, the filter screen can prevent that some debris that float in the surface of water from getting into the escape canal.

Furthermore, the inside wall of desilting ditch and escape canal all is provided with the one deck waterproof layer.

Through adopting above-mentioned technical scheme, the waterproof layer can prevent that sewage from oozing peripheral soil, prevents that soil quality from suffering destruction.

To sum up, the utility model discloses a beneficial technological effect does:

1. the arrangement of the dredging ditch, the drainage ditch, the purification block and the overflow port can generate the effects of pretreating rainwater and relieving the pressure of rainwater treatment equipment;

2. through the arrangement of the blocking filter screen and the filter screen, the effect of preventing sundries from entering the drainage ditch is achieved;

3. through the arrangement of the sewage collecting net and the chain, the dredging ditch is convenient to clean.
