Description

Driveway Rainwater Storage and Infiltration Facilities {STRUCTURE OF INFILTRATION TYPE FOR REDUCING SPILL OF RAIN}

The present invention relates to driveway rainwater storage and infiltration facilities, and more particularly, to reduce the initial stormwater runoff load and to reduce the load of the rainwater pumping station and the sewage treatment plant, thereby preventing flooding and flooding, and filtering device. It has a purification function for non-point pollution at the initial outflow and prevents the collapse of buildings and heat islands caused by lower groundwater level due to urban pavement by infiltrating rainwater that is being stored in the ground, and can be recycled as roadside water. It relates to storage and infiltration facilities.

Pollutants in urban streams can be classified into point sources and nonpoint sources.

Nonpoint source has been shown to reduce the pollution load in large part due to the maintenance of sewage pipes and advanced treatment of sewage treatment plants. However, management of nonpoint source only has limitations in reducing pollutant load of river and improving stream quality, and it is possible to restore water quality and water ecosystem of urban stream only by reducing pollutant load by nonpoint source. Non-point sources in urban areas vary, including land, roads, and roofs of buildings, but the largest loads are non-point sources on road surfaces. This is because dust, oil, and heavy metals and tire wear caused by roads are discharged in the form of spills due to the initial rainfall during rainfall. This increases the pollutant load of the sewage treatment plant, overflows from the insufficient sewage pipe to the nearby stream, and directly causes a fatal effect on the river ecosystem, causing fish to die.

In addition, the urban area has a shorter rainfall runoff time due to pavement by the impermeable layer, and the extent and frequency of the habitual flooding zone is increasing due to local guerrilla heavy rain caused by climate change. However, it is not a feasible alternative to increase the sewage capacity for temporary guerrilla heavy rains or to expand the reservoir, as well as the difficulty of securing available land.

Both non-point source problems due to early rainfall and immersion due to guerrilla heavy rain both result from rainfall runoff. The difference is that the nonpoint source is a problem at the beginning of rainfall, and the problem of inundation is that the peak rainfall in which the rainfall is intensified in earnest and the time when rainfall spilled after peak rainfall is collected downstream.

Rainwater abatement facilities are classified into an initial good storage type and a peak load storage type depending on the structure of the valve facility.

The initial rainwater storage type excellent runoff reduction facility directly drains rainwater collected by rain gutters into the storage tank, and when the water level of the storage tank is full, it flows out to the storm drainage buried in the middle of the road. To this end, a valve is installed in the connection pipe from the rain gutter to the conduit and normally closed so that the initial rainwater flows directly into the storage tank during rainfall, and the valve is opened in the Cheongcheon and discharged through the conduit.

Peak load storage type stormwater runoff reduction facility directly drains rainwater from the rainwater drain through the sewer conduit pipe and prevents part of the inlet diameter of the connection pipe so that the rainfall of strong rainfall intensity flows over to the storage facility. It is a feature of the set.

The principle of operation of stormwater abatement facilities is as follows.

1. Excellent excellent storage type stormwater discharge control device

end. Classification sewerage area

The initial excellent stormwater runoff reduction facility can be maximized when installed on roads with classified sewer pipes.

Non-point pollutants caused by the initial rainwater on the road surface discharged to the river in rainy weather are stored in the stormwater discharge reduction facility, and then discharged through the sewage pipe in Cheongcheon-si to be discharged after treatment in the sewage treatment plant. When the rain tank is full, the pollutants on the road have already been removed, so the clean rainfall runoff is discharged to the storm drain in the middle of the road and discharged into public waters.

I. Combined Sewer Area

The installation of the initial excellent stormwater runoff reduction facility on the road where the combined sewage pipe is installed can discharge the stored initial rainwater to Cheoncheon-si and transfer it to the sewage treatment plant, thereby reducing the load of the sewage treatment plant during rainfall.

2. Peak load storage type storm drain

It is installed for the purpose of reducing the peak rainfall runoff load of sewage pipes in guerrilla heavy rains, and acts as the same mechanism in the combined and classified areas. As the diameter of the inlet of the connection pipe from the rain gutter to the sewer pipe is reduced to a certain section, the rainfall runoff of initial rainfall intensity is directly discharged, but the runoff of peak load rainfall intensity is increased so that the water level in the rain gutter increases, which is excellent. It is stored in the storage tank of the spill reduction facility. If the water level in the reservoir is full, it will flow out into the sewer pipe through a large overflow pipe. When the rainfall intensity is weakened, the rainfall runoff stored in the reservoir flows into the rain gutter by its own water level and the slope of the reservoir and is discharged through the connecting pipe to the sewer pipe.

On the other hand, in order to prevent flooding, it is effective to reduce impermeable layers of roads or roads, or to install reservoirs such as reservoirs, but there are very limited areas where permeable pavement can be applied, and there are many negative views on the effects. In addition, according to the plan of use and development of the site, which is becoming increasingly dense, it is a reality to secure an appropriate reservoir or even convert the existing reservoir into other uses.

In order to solve this phenomenon, there is a rainwater abatement facility of Patent No. 0885534 filed and patented by the present applicant.
