Abstract
Description
본 발명은 수압을 받는 지하층 콘크리트 구조물의 누수 방수공법에 관한 것이다.The present invention relates to a waterproof method for leaking underground concrete structures under water pressure.
일반적으로 콘크리트 구조물은 크랙 및 타설불량 등의 하자요인에 의하여 누수가 발생되는데, 특히 지하층의 경우 지하로 내려갈수록 구조물에 가해지는 수압은 비례적으로 높아지기 때문에 누수부분을 통해 상당한 수압에 의하여 구조물내로 물이 상당한 압력으로 분수처럼 지하수가 분출되고 있다.In general, concrete structures leak due to defects such as cracks and poor casting, especially in the case of the basement floor, the water pressure applied to the structure increases proportionally as it goes down to the basement. Under this considerable pressure, groundwater is ejected like a fountain.
종래의 방수방법은 누수부분의 적정위치에 구멍을 형성하고 액체상태의 시멘트페이스트 등의 주입재를 구멍에 설치한 주입구로 고압 주입으로 압입 충진하는 공법으로 행하여지고 있다.The conventional waterproofing method is carried out by a method of forming a hole at an appropriate location of the leaked portion and filling-in by high pressure injection with an injection hole provided with an injection material such as a liquid cement paste in the hole.
그러나 지하층에와 같이 상당한 수압을 받아 누수되는 곳에서는 고압주입기로 시멘트페이스트등의 주입재를 주입하게 되는데 이 주입재는 경화시간이 길어서 경화 전에 분출되는 지하수압에 의하여 유입되지 못하고 역으로 유출되는 역류 및 침하되는 현상이 발생한다. 이때 주입재를 급결시키지 못하면 재주입이 불가능하고 그로 인하여 이미 주입된 주입재가 침하현상이 발생된 상태로 경화되면 재주입시 공극이 발생되어 재 누수의 원인이 된다.However, in places where water leaks due to a considerable pressure, such as in the basement layer, the injection material such as cement paste is injected into the high pressure injector. Phenomenon occurs. At this time, if the injection material is not fastened, re-injection is impossible, and if the injected material is hardened in a state where settlement occurs, voids are generated during re-injection, which causes re-leakage.
또한 겔상태의 주입제가 고압 주입기의 압력에 의하여 주변에 매설된 하수로, 전력선, 맨홀등의 파손된 부분으로 까지 침투가 이루어져 경화되므로서 하수구를 막는 경우등의 또다른 문제를 야기시키게 되는 것이다.In addition, the gel injector penetrates into the sewage, which is buried around by the pressure of the high pressure injector, and hardens by infiltrating into a damaged part such as a power line or a manhole, thereby causing another problem such as blocking the sewer.
따라서 종래의 방수공법은 수압이 극히 약하거나 수압이 발생되지 않은 곳에서 적용할 수 있고 지하층과 같이 상당한 수압이 작용하는 곳은 적용하기 어려운 문제점이 있었다.Therefore, the conventional waterproof method has a problem that it is difficult to apply where the water pressure is extremely weak or where no water pressure is generated, and where considerable water pressure is applied, such as the basement layer.
본 발명의 목적은 수압이 발생되는 지하층의 콘크리트 구조물에서의 주입재를 주입, 급결로 방수처리되도록 하면서 주변의 지하 매설물에 주입재의 침투를 막으면서 지반을 안정시키도록 한 수압을 받는 지하층 콘크리트 구조물의 누수 방수공법을 제공함에 있다.An object of the present invention is to leak the water of the basement concrete structure receiving water pressure to stabilize the ground while preventing the penetration of the injection material into the surrounding underground buried material while the injection material in the concrete structure of the underground layer where the water pressure is generated to be waterproofed by rapid injection To provide a waterproof method.
본 발명은 상기한 목적을 구현하기 위하여 안출된 것으로, 지하 콘크리트 구조물의 누수 적정위치에 천공한 구멍에 주입관을 설치한 급지수용 팽이로 타공으로 밖아 설치되는 주입관 설치공정과, 믹서기에 의하여 혼합된 주입재를 고압주입기에 의해 주입관에 설치된 이중밸브를 통해 공급되도록 하는 주입재 주입공정과, 또 다른 고압주입기에 의하여 상기 이중밸브를 통해 주입재 주입공정과 함께 급결재를 각각 동시에 쇼트할 수 있도록 하는 급결재 주입공정으로 하여 누수장소의 구조물 배면에 충입시키어 압착, 고결되도록 함을 특징으로 한다.The present invention has been made in order to achieve the above object, the injection tube installation process is installed outside the perforated with a feeder top installed in the hole drilled in the hole perforated at the proper location of the leakage of the underground concrete structure, and mixed by a mixer The injection material injection process for supplying the prepared injection material through the double valve installed in the injection pipe by the high pressure injector, and the high pressure injector through the injection material injection process through the double valve by the high pressure injector, respectively It is characterized in that the filling injection process is filled into the back of the structure of the leaking place to be compressed and solidified.

도 1은 본 발명의 실시예를 보인 블럭도로,1 is a block diagram showing an embodiment of the present invention,
누수되는 지하 콘크리트 구조물(1) 적정위치에 지반층까지 천공하여 연질파이프로 된 주입관(2)을 설치한 급지수용 팽이(3)로 천공된 구멍(11)을 통해 분출되는 지하수 차단 및 주입재 압입을 위해 타공으로 밖는 주입관 설치공정과,Underground concrete structure (1) leaking Underground water blockage and injection material injection through the hole (11) drilled into the feeder top (3) with a drill pipe (2) made of soft pipes drilled to the ground layer at an appropriate location Inlet pipe installation process and
믹서기(4)에 의하여 혼합된 시멘트페이스트인 주입재(5)를 고압주입기(6)에 의해 주입관(2)라인에 설치된 이중밸브(7)를 통해 공급되도록 하는 주입재 주입공정과,An injection material injection step of supplying the injection material 5, which is the cement paste mixed by the mixer 4, through the double valve 7 installed in the injection pipe 2 line by the high pressure injection machine 6;
또 다른 고압주입기(9)에 의하여 상기 이중밸브(7)를 통해 주입재 주입공정과 함께 급결재(8)를 공급하는 급결재 주입공정으로 이루어짐을 특징으로 하고 있다.Another high-pressure injector (9) is characterized in that it consists of a quickener injection process for supplying the quickener 8 together with the injection material injection process through the double valve (7).
상기와 같이 이루어진 공정에 대하여 이를 구체적으로 살펴보면,Looking specifically at the process made as described above,
누수되는 지하 콘크리트 구조물(1) 적정위치에 지반층까지 천공하면 지하수가 분출하는데 토질에 따라 토사가 분출하는 경우가 있다. 그리고 천공된 구멍(11)에 연질 파이프의 주입관(2)을 연결한 급지수용 팽이(3)로 타격하여 막게되는데, 급지수용 팽이(3)는 유입이 용이하도록 테이퍼지게 형성되고 재질은 물의 접촉에 의하여 팽창되는 목재를 적용하는 것이 바람직하다. 이는 구멍(11)에 밀착 수압 및 추후 고압 주입시 빠지지 않고 고정시키게 되는 것이다.Underground concrete structures leaking (1) When perforated to the ground floor at an appropriate position, the groundwater is ejected, and the soil may be ejected depending on the soil. And it is blocked by hitting the feeder top 3 connected to the injection pipe (2) of the soft pipe to the perforated hole (11), the feeder top (3) is formed to be tapered for easy inflow and the material is in contact with water It is preferable to apply wood which is expanded by. This is to be fixed without being pulled out in close contact with the hole 11 water pressure and later high pressure injection.
그리고 믹서기(4)로 혼합되는 주입재(5)와 급결재(8)는 각각 고압주입기(6)(9)로 이중밸브(7)를 통해 혼합되면서 각각 유입되어 주입관(2)을 통하면서 혼합되어 지하 콘크리트 구조물(1)의 배면의 공극에 주입되고 주입량은 이중밸브(7)의 각 벨브의 조정으로 상황에 따라 조정할 수 있도록 한다. 이는 급결재의 주입량을 조절하여 주입관(2)내에서 주입재가 급결되는 것을 방지하면서 주입할 수 있도록 한 것이다.And the injection material (5) and the fastener (8) to be mixed in the mixer (4) are respectively introduced into the high pressure injector (6) (9) through the double valve (7) while being introduced through the injection pipe (2) It is injected into the air gap on the back of the underground concrete structure (1) and the injection amount can be adjusted according to the situation by the adjustment of each valve of the double valve (7). This is to adjust the injection amount of the fastening material to be injected while preventing the injection material in the injection pipe (2).
상기 주입재는 시멘트에 시멘트가 경화시 팽창시키는 팽창재 및 공극사이에침투가 용이하도록 유동화재를 믹서한 혼합제로 배합비율은 시멘트 중량당 팽창재 0.45% 유동화재 0.4-1.2%의 비율로 하여 적정농도를 갖도록 물과 혼합하여 얻어지고, 급결재는 규산소다와 물을 2:1비율로 혼합하여 얻어지는 것이 바람직하다.The injection material is a mixture of the fluidizing agent to facilitate penetration between the expansion material and the pores to expand when the cement is hardened in the cement, the mixing ratio is an appropriate ratio of 0.45% fluidizing agent 0.4-1.2% of the expansion material per weight of cement to have an appropriate concentration. It is obtained by mixing with water, and the quickening material is preferably obtained by mixing sodium silicate and water in a 2: 1 ratio.
이렇게 고압으로 급결재와 함께 동시에 겔상태로 주입된 주입재는 10-60초의 짧은시간에 급결재에 의하여 압착, 고결되면서 그 사이에 누수장소에 침투하여 방수처리 하므로서 수압에 의해 역류되지 않고 또한 주변 매설물까지 침투되지 않게 되는 것이다. 상기 급결시간은 물의 공급량에 따라 비례한다.The injection material injected into the gel at the same time with the fastener at high pressure is pressed and solidified by the quickener in a short time of 10-60 seconds, and penetrates into the leaking place in between, and it is waterproofed without being reversed by water pressure. It will not penetrate until. The quenching time is proportional to the amount of water supplied.
이상과 같이 본 발명은 주입재와 급결재를 각각 쇼트하여 이를 하나의 관에 의하여 혼합한 상태로 주입되어 압착, 고결시키므로서 지하 구조물의 수압에 의한 누수 부분을 효율적으로 방수할 수 있고 주변 매설물의 피해를 방지하는 등의 효과가 있다.As described above, the present invention shortens the injection material and the fastening material, respectively, and injects them in a state in which they are mixed by a single pipe, thereby compressing and solidifying the water, thereby effectively waterproofing the leaky part due to the water pressure of the underground structure and damaging the surrounding buried material. There is an effect such as to prevent.
