Description

지하저수식 빗물 저류조{Rain-water Retaining Facility for Keeping Water in Ground}Rain-water Retaining Facility for Keeping Water in Ground}

본 발명은 도로, 주차장, 광장 및 지붕 등에 내린 빗물을 지중에서 집수하여 정화/저류하기 위한 지하저수식 빗물 저류조에 관한 것이다.
The present invention relates to an underground low water stormwater storage tank for collecting and purifying rainwater discharged from roads, parking lots, squares and roofs.

우리나라는 경제성장과 더불어 과거 도시중심의 개발로 인해 빗물을 지반에 침투시키기보다 강이나 바다로 신속히 배출하는데 집중해 왔다. 그 결과 큰 비가 계속 되면 하천이나 하수도가 범람하는 재해가 발생하고 있다. 우리나라의 일인당 강수량은 세계 평균의 8분의 1로서 매우 적은 량이며 빗물은 소중한 자원임에도 불구하고 이것을 너무 빠른 속도로 외부에 내보내고 있다. 따라서 빗물에 대한 인식변화와 이를 유효하게 활용할 수 있는 구조가 필요하다In addition to economic growth, Korea has been focusing on the rapid urbanization of rainwater in the past, rather than infiltration of rainwater into the ground. As a result, if a large amount of rain continues, disasters such as flooding of rivers and sewers are occurring. The rainfall per capita in Korea is one eighth of the world average, which is very small, and rainwater is a valuable resource, but it is exporting it too quickly. Therefore, it is necessary to change the perception of rainwater and to use it effectively

지하저수식 빗물 저류조는 빗물을 지하에 저장해 두었다가 필요시 유효하게 활용하기 위해 고안된 것이다. 저장된 빗물은 녹지의 살수, 화장실의 용수, 재해 비상용수, 유수지로서의 이용은 물론, 지하수로의 환원에 의한 하천의 정화나 자연수해를 방지하는 효과가 있다.Underground low water storm reservoirs are designed to store rainwater underground and use it effectively when needed. The stored rainwater has the effect of preventing the purification of the river and the natural waters caused by the reduction of the groundwater to the ground water as well as the use of the green water, the water of the toilet, the emergency water for the disaster,

그런데 종래의 지하저수식 빗물 저류조는 특허 제10-1003526호 등과 같이 진흙 등으로 오염된 빗물을 별도 정화하지 않고 그대로 집수하여 저류하는 것이 대부분이었다. 그러나 오염된 빗물이 그대로 저장되기 때문에 빗물을 재활용하는데 어려움이 있고, 또한 저류조 내부에 진흙 등이 퇴적되기 때문에 저류조 관리에 어려움이 있었다.
However, in the conventional underground low-rainfall storm reservoir, most of the rainwater contaminated with mud or the like as in Patent No. 10-1003526 is collected and stored without being purified separately. However, since the contaminated rainwater is stored as it is, it is difficult to recycle the rainwater. Also, mud is deposited inside the storage tank, which makes it difficult to manage the storage tank.

본 발명은 종래 지하저수식 빗물 저류조의 단점을 개선하고자 개발된 것으로서, 빗물을 효과적으로 정화하여 저장할 수 있고 유지관리가 용이한 새로운 빗물 저류조를 제공하는데 기술적 과제가 있다.
The present invention has been developed to improve the disadvantages of conventional underground low water stormwater storages, and it is a technical problem to provide a new storm water storer that can effectively purify and store rainwater and is easy to maintain.

상기한 기술적 과제를 해결하기 위해 본 발명은, 빗물을 지중에서 집수하여 정화/저류하기 위한 지하저수식 빗물 저류조로서, 빗물이 유입되어 하부의 침사부에 이물질이 침전되면서 집수되는 집수부; 상기 집수부에 유입된 빗물이 이송되어 필터에 의해 상향 여과되는 정수부; 차수재로 피복된 공간 내부에 유공관에 의한 체수재가 충전되며, 상기 정수부에서 상향 여과된 빗물이 체수재를 따라 하향 이송되면서 체수재 내부에 저장되는 저수부; 상기 저수부 말단 하부와 연결되며, 상기 저수부에 저장된 빗물이 이송되어 빗물재활용에 제공하게 되는 이수부;를 포함하여 구성되는 것을 특징으로 하는 지하저수식 빗물 저류조를 제공한다.
According to an aspect of the present invention, there is provided a subterranean low rainwater stor- age tank for collecting and purifying rainwater from a ground, comprising: a collecting part for collecting foreign matter into the lower part of the sinker through rainwater; An integer part of which the rainwater flowing into the water collecting part is transferred and is upwardly filtered by the filter; A water reservoir in which a sieve member filled with a porous tube is filled in a space covered with a car body material and the upwardly filtered rainwater in the purified water portion is transported downward along the sieve body to be stored in the body material; And a drain connected to the bottom of the bottom of the bottom of the water reservoir and provided for recycling the rainwater stored in the bottom reservoir.

본 발명에 따르면 다음과 같은 효과를 기대할 수 있다.According to the present invention, the following effects can be expected.

첫째, 제한된 수자원의 재생, 유효이용이 가능해진다. 특히 빗물에 포함되는 오탁물, 유분 등을 효과적으로 제거할 수 있기 때문에, 주변 수역의 보전이나 하수처리장의 부하 저감에 공헌하며, 처리된 빗물을 저장하고 재이용하여 수자원의 유효 이용을 실현할 수 있다.First, it is possible to recycle and use limited water resources. Particularly, it is possible to effectively remove pollutants and oil contained in rainwater, thereby contributing to the conservation of surrounding water bodies and the reduction of the load on the sewage treatment plant, and the processed rainwater can be stored and reused to realize effective use of water resources.

둘째, 저수부의 체수재로 공극율을 90% 이상 확보할 수 있는 유공관을 이용하기 때문에 많은 량의 빗물저장이 가능하다. 특히 유공관을 연속구조로 설치하므로 내부공극률이 높아 많은 량의 빗물을 저장할 수 있고 더불어 물을 단시간에 유출입시킬 수 있다.
Secondly, it is possible to store a large amount of rainwater because it uses a porosity pipe capable of securing 90% or more of porosity as a body material of the reservoir. In particular, since the pipe structure is installed in a continuous structure, the internal void ratio is high, so that a large amount of rainwater can be stored and water can be flown in a short time.
