본 발명은 지하철등과 같은 지하 구조물의 지하 구조물 벽체에 시공이음부 또는 거푸집 이음부등과 같은 취약부에 시공되는 방수 공사시 방수 시트를 벽면에 부착하기 전에 지하 구조물의 지하 구조물 벽면에 형성된 시공 이음부 또는 거푸집 이음부에 지하 구조물의 길이 방향으로 일정한 크기의 기성제품으로 만든 소구경의 유공관을 삽입 또는 부착 설치한 후에 그 위에 방수 시트를 부착하고 보호몰탈을 바르고 양생과정을 거쳐 지하 구조물의 구축을 완료하고 난 후에 지하 구조물의 지하 구조물 벽체에 기히 매설된 유공관을 통하여 누수가 발생하거나 벽체에 누수가 발생하였을 경우에 방수검사용으로 기히 매설된 유공관을 통하여 그라우팅액을 압력 주입하여 해당 부위에 방수를 실시하는 벽체 간이방수검사 장치 및 그를 이용한 누수지수 그라우팅방법에 관한 것이다.The present invention is a construction joint formed on the wall of the underground structure of the underground structure before attaching the waterproof sheet to the wall during the waterproof construction to be constructed in weak parts such as construction joints or formwork joints in the underground structure walls of underground structures such as subway or After inserting or attaching small-diameter perforated tubes made of ready-made products of a certain size in the longitudinal direction of the underground structure in the formwork joints, attach the waterproof sheet on them, apply protective mortar, and finish the construction of the underground structure through curing process. After leaking through the perforated pipes which are buried in the wall of the underground structure of the underground structure or when the leaks occur in the wall, the grouting solution is pressure-injected through the perforated pipes for waterproof inspection. Wall simple waterproof test device and leak index using it It relates to a routing method.

이러한 방법은 지하 구조물이 완성된 후에는 지중에 지하 구조물이 매립되어 지하 구조물에서 취약부인 시공이음부 또는 거푸집이음부등에 완벽한 방수가 시공되지 않아 누수가 발생되었을 때 방수검사용으로 기히 매설한 유공관을 통하여 그라우팅을 실시하여 누수의 원인이된 부위를 방수그라우팅을 하여 충전시켜 누수를 차단하는 완벽한 방수를 하는데 그 목적이 있다. 이것은 지하 구조물의 취약부에대한 누수검사를 병행하면서 유공관을 통하여 누수여부를 확인한 후에 방수가 안된 부분에는 유공관을 통하여 재차 방수를 시공하는 것이다.In this method, after the underground structure is completed, the underground structure is buried in the ground, so the waterproof pipes are completely buried for waterproof inspection when leaks occur because perfect waterproofing is not applied to the construction joints or formwork joints which are weak parts of the underground structures. Through the grouting through the waterproof grouting of the area causing the leak is filled with the purpose of perfect waterproof to block the leak. This is to check the leakage through the perforated pipe while conducting the leak test on the weak part of the underground structure, and then waterproof again through the perforated pipe at the part that is not waterproof.

종래에는 지하 구조물을 시공하면서 벽체등에 면정리를 한 후에 프라이머를 도포하고 그 위에 방수시트를 부착한 후에 보호몰탈로 방수시트를 보호하는 방수공사를 실시하여 왔다. 그러나 이러한 방수방법에는 방수시트가 균일하게 벽체와 접착이 완벽하게 되지 않고 중간중간에 들뜨게 되는 점과 또한 지하 구조물의 시공이음부 또는 거푸집이음부등과 같은 시공상 반드시 설치되어야 하는 부분이 콘크리트의 재료분리 또는 거푸집에 의해 충분한 밀실 다짐이 이행되지 않아 벽체에 무수한 공극이 발생된 채로 시공되어 방수가 이뤄지게되면 추후에 이러한 시공상의 취약부분이 누수의 원인이되는 취약부로 발전이되는데 지중에 설치된 지하구조물인 관계로 이러한 누수부위를 용이하게 발견하기가 대단히 어려우며,설령 발견을 하더라도 누수부위에 재차 방수작업을 하기 위하여 주위의 모든 토사를 제거하여야하고 누수부위를 일정부분 제거한 다음에 그라우팅 또는 방수시트를 이용하여 재공사를 시행하여야 하는 번거로움과 재시공에 따른 제경비와 누수의 재발이 되는지를 끊임없이 관리를 하여야 하는 문제점이 있었다.Conventionally, after constructing the surface of the basement while cleaning the surface and the like after applying a primer and attaching the waterproof sheet on it has been carried out waterproof construction to protect the waterproof sheet with a protective mortar. However, in this waterproofing method, the waterproof sheet is not uniformly adhered to the wall, but is lifted in the middle, and also the parts that must be installed in construction such as construction joints or form joints of underground structures are materials of concrete. If sufficient compaction is not fulfilled due to separation or formwork, and the construction is made with numerous voids on the wall, and waterproof is achieved, these weak parts in the construction are developed into weak parts causing leakage. As a result, it is very difficult to find such leaks easily, and even if it is found, all soils around it should be removed to waterproof the leaks again. The hassle of having to reconstruct There was a problem of constantly managing whether recurring expenses and leaks caused by reconstruction.

본 발명은 이상과 같은 사항을 감안하여 창출된 것으로서, 지하 구조물의 지하 구조물 벽체에 누수의 여부를 점검하여 방수공사의 완벽여부를 점검하면서 누수가 발생되면 해당 부위에 방수검사용으로 기히 매설되어 있는 유공관을 통하여 방수 그라우팅액을 압입 주입하여 해당부위에 그라우팅액이 충전되어 누수를 방지할 수 있도록하는 벽체 간이방수검사장치 및 그를 이용한 누수지수 그라우팅 방법에 관한 것이다.The present invention was created in view of the above matters, and if the leak occurs while checking the completeness of the waterproofing work by checking the leakage of the underground structure wall of the underground structure, which is already buried for waterproof inspection in the corresponding area. The present invention relates to a simple wall waterproofing inspection device and a leak index grouting method using the same, by injecting a waterproof grouting solution through a pore tube and filling the grouting solution to prevent leakage.

It characterized in that to perform.

이하 첨부된 도면에 의하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 있어서 지하 구조물의 지하 구조물 벽체에 벽체 간이방수검사장치를 설치한 것을 보여주는 단면도로서 지하 구조물(10)의 설치를 위하여 지하 지반에 기초콘크리트(15)를 타설양생하고 그 위에 지하 구조물(10)을 구축하게되는데 이때 지하 구조물의 설치크기등을 감안하여 시공이음부(12)를 설치하거나 거푸집의 크기에 의하여 거푸집 이음부(12)를 두게 된다. 이러한 시공이음부 또는 거푸집이음부(12)와 같은 이음부가 타설된 콘크리트의 재료분리 현상으로 인하여 벽체가 수많은 공극으로 형성되거나 또는 거푸집에 의하여 밀실하게 콘크리트의 다짐이 시행되지 못하여 역시 공극이 형성되게 된다. 이러한 취약부에 누수가 발생되게 되는데 이와같은 취약부에 거푸집을 설치할 때 두게되는 면목에 의하여 형성되는 V자 형태 또는 사다리꼴 형태의 홈(13)을 이용하여 지하 구조물(10)의 길이 방향으로 유공관을 삽입설치하거나 또는 시공이음부의 면에 유공관을 부착설치하고 "ㄷ"자 형태의 유공관 고정구(18)로 지하 구조물 벽체에 유공관을 고정시킨다. 이때미리 매설하거나 부착된 유공관을 통하여 누수가 발생되면 유공관(16)을 통하여 그라우팅을 실시하기 위하여 지하 구조물 벽체 연결면(20)의 중간부분 까지 유공관(16)을 홈에 삽입한 후에 유공관을 마개(17)로 막아 놓거나 이음부에 유공관을 부착시키고 벽체의 표면에 프라이머를 도포한 후에 방수시트(14)를 접착시공하고 보호물탈을 타설양생하여 방수시트를 보호하면서 벽에 밀착되게 한다. 이렇게 지하 구조물(10)의 구축 공사가 완료된 후에 누수가 발생될 경우에는 유공관(16)을 통하여 일정한 압력으로 그라우팅액을 압력 주입하여 누수가 발생되는 부분을 그라우팅액으로 충전시켜 누수를 방지하는 것이다. 주로 지하 구조물의 벽체의 기초 콘크리트 위에 설치된 1단 벽체 또는 2단 벽체에 설치하거나 하단부의 벽체와 기초 콘크리트 위에 설치되는 헌치와의 경계부에 설치하게 되는데 이러한 부위에 누수가 많이 발생하게 되며 이러한 부위에 발생된 물이 모여서 누수가 진행되는 경우가 자주발생되기 때문이다. 유공관의 직경은 1 ~ 1.5㎝이며 바람직한 것은 1㎝이다. 또한, 면목에 의하여 형성된 V자형태 또는 사다리꼴형태의 홈의 깊이는 2㎝이며 그라우팅액을 유공관내에 주입할 때에 압력의 크기는 2 ~3 ㎏/㎠이다.1 is a cross-sectional view showing the installation of a simple wall waterproofing inspection device on the wall of the underground structure of the underground structure in the present invention for the installation of the underground structure 10 to pour the foundation concrete 15 in the underground ground and basement thereon The structure 10 is to be constructed in which the installation joint 12 is installed in consideration of the installation size of the underground structure or the formwork joint 12 is placed by the size of the formwork. Due to the material separation phenomenon of the concrete in which the joints, such as the construction joints or the mold joints 12, are poured, the walls are formed with numerous voids or the compacts are not firmly carried out by the molds, thereby forming voids. . Leakage is generated in such a weak part, by using a V-shaped or trapezoidal groove 13 formed by a face placed when installing the formwork in such a weak part to insert the perforated tube in the longitudinal direction of the underground structure (10). Or install a hole on the surface of the construction joints, and the hole in the "c" shaped hole tube 18 to fix the hole in the wall of the underground structure. At this time, when the leak occurs through the buried pipes or buried in advance, the hole pipes 16 are inserted into the grooves to the middle of the underground structure wall connection surface 20 to grout through the hole pipes 16 and then stop the hole pipes ( 17) After sealing or attaching the perforated pipe to the joint and applying the primer on the surface of the wall, the waterproof sheet 14 is adhered and the protective material is removed by curing curing the waterproof sheet to be in close contact with the wall. When leakage occurs after the construction work of the underground structure 10 is completed, the grouting solution is injected into the grouting liquid at a constant pressure through the perforated pipe 16 to fill the portion where the leakage occurs with the grouting solution to prevent leakage. It is mainly installed on the first or second wall installed on the foundation concrete of the wall of the underground structure or at the boundary between the wall of the lower part and the haunches installed on the foundation concrete. This is because water leaks often occur due to the gathered water. The diameter of the perforated tube is 1 to 1.5 cm, preferably 1 cm. In addition, the depth of the V-shaped or trapezoidal groove formed by the face wood is 2 cm, and the pressure is 2 to 3 kg / cm 2 when the grouting liquid is injected into the perforated tube.
