Description

Rotary type bio-retention equipment having hybrid ecological function for treating non-point pollutant of intersection}

The present invention relates to a rotary ecological complex bioretention facility for non-point pollution treatment at intersections. More specifically, it treats non-point pollutants from rainfall runoff from all directions of intersections and attracts depleted ground water. And it can be preserved, and the rotary type eco-composite bioretention facility for the intersection non-point pollution treatment to perform a complex ecological function, such as having a function of purifying the vehicle exhaust gas by forming a green area at the intersection of the city.

In general, intersections are divided into intersections in the form of cross roads and rotary type intersections.

Intersections in the form of cross roads are designed to cross three, four, or five branch roads as they are, and to allow vehicles to proceed from each branch road to another branch alternately according to signal conditions. Intersections connect three, four, or five intersections by annular loops, and vehicles that want to proceed from each branch to another branch drive along the annular loop without signal, then turn right to the desired branch. To do that.

Cross road-type intersections require relatively narrow areas to create intersections. Therefore, this is an intersection type that is mainly employed in countries with a narrow urban area, such as Korea. Since vehicles that want to proceed from each branch road to another branch must travel according to the alternating signal present, the stopping time becomes longer, resulting in traffic congestion to each branch. In many cases, the vehicle is unable to exit the center of the intersection before changing to the next traffic signal, and these vehicles interfere with the traffic that is driven by the normal traffic, resulting in traffic congestion at the intersection and speeding at the intersection. There are difficult problems such as frequent traffic accidents.

On the other hand, rotary type intersections connect three, four, or five branch roads by annular loops so that vehicles entering the loops from each branch run through the loop. While you can proceed right by turning to the desired basin, there is no need to wait for signal manifestation and the circular loop can absorb the traffic, which leads to smooth traffic communication, while the large area is needed to create an intersection. If the area is small, there is a problem that cannot be employed.

In Korea, the intersection of three, four and five is mostly crossroads type intersections, but the number of rotary type intersections is gradually increasing.

Generally, a traffic island is formed at the center of a rotary type intersection. These traffic islands are used as emergency stoppage segments or simply partitioned by barriers, and vegetation is planted in them to perform simple landscape functions.

On the other hand, as the United Nations has announced, Korea is required to expand its groundwater as much as possible, as it is a water-scarce country that includes not only precipitation but also underground water. Accordingly, various types of infiltration ditches and underground water storage facilities have been developed in the past.

An example of a conventional penetration groove is disclosed in Korean Patent No. 0977882. The infiltration ditch of this patent is composed of inlet, filter and outlet, and has infiltration holes at the bottom of the inlet, the filter and the outlet so that the influent such as rainfall runoff can be filtered and then penetrated into the basement. . However, these infiltration ditches are simply composed of a channel type, and are limited to filtration of inflows such as rainfall runoff, which is constrained to be installed in rotary intersections. There is such a problem.

Accordingly, an object of the present invention is to provide a rotary ecological complex bioretention facility for an intersection non-point pollution treatment that can satisfy both the effective treatment of rainwater runoff and the urban landscape at the same time, and to expand the insufficient groundwater. will be.

The filter permeation passage is provided with a bypass tank to allow the inflow to flow directly into the vegetation permeation passage when the rainfall is increased to increase the inflow quantity.

The bypass tank is composed of a pair of transverse walls connecting the outer ring wall and the intermediate ring wall and a bottom plate connecting the lower end of the transverse wall by crossing the filtration penetration channel.

During the initial rainfall with little rainfall, as shown in FIG. 5 and FIG. 7, the rainfall runoff flowing through the outer ring-shaped wall 1 around the intersection with the rainfall directly descending to the filter penetrating ditch 10 is filtered (13). After being filtered by), it penetrates underground through the penetration hole 12 formed at the bottom thereof. When the rainfall increases and the quantity of rainfall runoff flowing into the filtration permeable trench 10 becomes larger than the quantity of permeation into the underground through the penetration hole 13, the rainfall runoff in the filtration permeable trench 10 is the intermediate ring-shaped wall 2. Rainfall flows into the vegetation penetrating ditch 20, and the rainfall runoff flowing into the vegetation penetrating ditch 20 passes through the vegetation soil 23, and after the non-point pollutant is filtered, it penetrates through the infiltration hole 22. Infiltrate. Rainfall outflow water in the vegetation infiltration path 20 is introduced into the infiltration-type rain garden 30 through a through hole 34 drilled in the inner ring-shaped wall (3).
