Description
본 발명은 배면방수 그라우팅용 거푸집 간격유지장치에 관한 것으로서, 더욱 상세하게는 콘크리트에 매설되는 거푸집 간격유지장치를 통해 콘크리트벽체의 배면으로 방수약액을 주입하므로서 콘크리트 타설 후에도 방수하자를 완벽하게 보수할 수 있도록 한 배면방수 그라우팅 방법용 거푸집 간격유지장치에 관한 것이다.The present invention relates to a formwork spacing device for waterproofing back grouting, and more specifically, it is possible to completely repair the waterproofing flaw after pouring concrete by injecting a waterproofing chemical into the back of the concrete wall through the formwork spacing device embedded in concrete It relates to a formwork spacing device for a backside waterproof grouting method.
일반적으로, 지하에 콘크리트를 타설하여 콘크리트벽을 시공하고자 할 시에는 도 1과 같이 흙막이벽(1)과 소정의 간격을 두고 내부거푸집(미도시)을 설치하고, 상기 내부거푸집의 내부에 내부거푸집과 소정의 간격을 유지하면서 타설된 콘크리트의 측압을 극복할 수 있도록 간격재, 폼타이등과 같은 거푸집 간격유지장치 (4)를 여러 개소에 설치한 후 상기 간격유지장치(4)의 각 단부를 거푸집(5)에 안정되게 지지시킨 상태에서 두 거푸집(5) 사이에 콘크리트를 타설하여 소정 두께의 콘크리트벽(6)을 조성하는 한편, 상기 콘크리트벽(6)의 양 거푸집(5)을 모두 탈형시킨 상태에서 콘크리트벽(6)의 배면에 물의 침투를 방지할 수 있는 방수벽(2)을 시공한 다음, 상기 방수벽(2)에 방수보호층(8)을 타설하고, 흙막이벽(1)과 방수보호층(8) 사이의 공간을 양질의 토사(7)로 되메움하게 된다. 이때, 상기 간격유지장치 (4)는 콘크리트벽(6)의 내부에 매설된다.In general, when you want to construct a concrete wall by placing concrete in the basement, as shown in Figure 1 to install an internal formwork (not shown) at a predetermined distance from the retaining wall (1), the internal formwork inside the internal formwork And form a mold spacing device (4) such as spacers, form ties, etc. in order to overcome the lateral pressure of the poured concrete while maintaining a predetermined spacing therebetween, and then each end of the spacing device (4) In the state of stably supporting the formwork (5), the concrete is placed between the two formwork (5) to form a concrete wall (6) of a predetermined thickness, while both formwork (5) of the concrete wall (6) demolding After the construction of the waterproof wall (2) to prevent the penetration of water on the back of the concrete wall (6), and then the waterproof protective layer (8) is poured on the waterproof wall (2), the earth wall (1) The space between the soil and the waterproof protective layer (8) 7) backfilled. At this time, the spacing device 4 is embedded in the concrete wall (6).
한편, 간격유지장치(4)는 콘크리트벽(6)의 표면까지 나오게 되고, 간격유지장치(4)와 콘크리트벽(6)과의 결합면이 서로 다른 이질재료로 인하여 외부방수 (2)가 확실히 되어 있지 않거나 방수층(2)에 하자가 발생할 경우에는 간격유지장치 (4)가 설치된 부분으로 누수가 발생하게 된다.On the other hand, the gap holding device (4) comes to the surface of the concrete wall (6), the external waterproof (2) is surely due to the heterogeneous material is different from the mating surface of the gap holding device (4) and the concrete wall (6) If not, or if a fault occurs in the waterproof layer (2), the leak occurs to the part where the gap retainer (4) is installed.
또한, 시공이음부는 시간차를 두고 타설된 신,구 콘크리트가 만나는 것으로 이어치는 부분의 면처리나 다짐등을 철저히 한다 하더라도 이 부분에 균열이 발생할 확률이 다분한 곳이며, 이곳 역시 방수에 매우 취약함이 있다. 또한, 신축이음도 역시 마찬가지로 콘크리트의 열팽창을 고려하여 일정한 간격을 이격시켜 구조물을 타설하게 되므로 이음부에 대한 방수처리가 확실하지 못할 시에는 방수하자가 발생하게 된다.In addition, the construction joints have a high probability of cracking in the areas even if the surface treatment or compaction of the parts leading to the meeting of new and old concrete, which are placed at different time intervals, is also vulnerable to waterproofing. There is this. In addition, expansion joints are similarly placed in consideration of thermal expansion of concrete, so that the structure is placed at a predetermined interval, so that the waterproofing occurs when the waterproofing is not sure about the joints.
상술한 바와 같은 이유에서 발생한 방수하자의 일반적인 보수방법은 누수되는 곳에 구멍을 천공하거나, 누수되는 균열부위에 주사기와 같은 주입장치를 붙여서 적절한 주입재를 주입하여 누수부위를 보수하였으나, 이러한 종래의 방법은 누수되는 균열에 주입하는 매우 소극적인 보수방법으로 보수가 완료된 직후에도 누수는 다른 취약부분을 따라 누수되는 악순환이 반복될 수 밖에 없다,The general repair method of the waterproof defect caused by the above-mentioned reasons repairs the leaky area by drilling a hole in the leak or attaching an injection device such as a syringe to the leaked crack and injecting an appropriate injection material. This is a very passive repair method that injects leaks into cracks. Even after repairs are completed, the leakage cycle is accompanied by a vicious cycle of leaking along other weak areas.
상기와 같은 문제들을 해소하기 위하여 요즈음에는 구조물의 흙과 접하는 부위, 즉 배면에 방수약액을 주입하여 배면전반에 걸쳐 방수층을 설치하는 방법이 나오고 있으나 이 공법은 코아드릴기로 콘크리트벽을 천공하여 그 배면에 방수약액을 주입하기 때문에 콘크리트벽의 구멍을 천공하는 동안에 그 내부에 매설된 철근들이 절단되어 이 부분에 부식이 진행되는 등의 열화현상으로 구조물에 심각한 손상을 주는 문제점이 있었다.In order to solve the above problems, a method of installing a waterproofing layer over the entire surface of the structure by injecting a waterproofing chemical into the soil contacting part of the structure, that is, the back surface of the structure has been developed. Since the injection of the waterproofing chemical into the concrete wall while drilling holes in the concrete was embedded there is a problem that serious damage to the structure due to deterioration phenomenon, such as corrosion proceeds to this part.
따라서, 본 발명은 상기와 같은 문제점을 감안하여 창출한 것으로서 콘크리트에 매설되는 거푸집 간격유지장치를 통해 콘크리트벽체의 배면으로 방수약액을 주입하여 배면전체에 방수층을 형성하므로서 콘크리트 타설 후에도 방수하자를 완벽하게 보수할 수 있도록 한 배면방수 그라우팅 방법용 거푸집 간격유지장치를 제공함에 그 목적이 있다.Therefore, the present invention was created in view of the above problems, and by injecting the waterproofing chemical into the back of the concrete wall through the formwork gap retaining device embedded in the concrete to form a waterproof layer on the entire back surface to completely waterproof even after pouring. It is an object of the present invention to provide a formwork spacing device for a back waterproofing grouting method for repairing.

먼저, 상기 콘크리트벽체(200)를 타설할 때 이의 여러 개소에 거푸집 간격유지장치(100)를 매설한다.First, when pouring the concrete wall 200, the mold spacing device 100 is embedded in several places thereof.
상기와 같이 콘크리트벽체(200)가 타설되어 있는 상태에서 상기 콘크리트벽체(200) 배면에 방수벽(400')을 시공하고자 하면, 상기 거푸집 간격유지장치(100)의 약액주입공(111)에 그라우팅장치의 노즐부(500)를 삽입하여 콘크리트벽체(200)의 배면에 방수약액을 주입. 방수벽(400')을 형성하는 한편, 상기 거푸집 간격유지장치(100)의 약액주입공(111)을 개폐구(120)로 밀봉한다.As described above, when the waterproof wall 400 'is to be installed on the rear surface of the concrete wall 200 in the state where the concrete wall 200 is poured, grouting to the chemical liquid injection hole 111 of the formwork spacing device 100 Inserting the nozzle portion 500 of the device to inject the waterproofing chemical to the back of the concrete wall (200). While forming the waterproof wall 400 ′, the chemical liquid injection hole 111 of the formwork gap maintaining device 100 is sealed with the opening and closing hole 120.
여기에서, 상기 콘크리트벽체(200)의 여러 개소에 매설되는 거푸집 간격유지장치(100)는 크게 나누어 원통형상의 간격유지관체(110)와, 이를 차폐시키는 개폐구(120)로 구분된다.Here, the formwork gap maintaining device 100 embedded in several places of the concrete wall 200 is largely divided into a cylindrical gap maintaining tube 110 and the opening and closing port 120 for shielding it.
즉, 간격유지관체(110)는 내,외부거푸집에 지지되어 콘크리트벽체(200)의 전면과 배면을 관통할 수 있는 길이로서 그 내부에 약액주입공(111)이 형성되고, 간격유지관체(110)의 전방 단부 내면에 암나사부(112)가 형성된다. 이때, 상기 간격유지관체(110)의 외주부에 돌기부를 형성하여 콘크리트벽체(200)와의 결합력을 강화시킴이 바람직하다.That is, the gap maintaining pipe 110 is supported by the inner and outer molds and can penetrate the front and rear surfaces of the concrete wall 200, and the chemical liquid injection hole 111 is formed therein, and the gap maintaining pipe 110 is formed therein. The female thread part 112 is formed in the inner surface of the front end part. At this time, it is preferable to form a protrusion on the outer circumference of the gap maintaining tube 110 to strengthen the bonding force with the concrete wall 200.
그리고, 개폐구(120)는 그 일단의 헤드부(121)에 간격유지관체(110)로부터 공구(육각렌치, 또는 스패너등)를 이용하여 이를 분리 또는 착설시킬 수 있게 키 또는 키홈과 같은 고정.해제수단(122)이 형성되고, 결합축(123)의 외주면 일부에 간격유지관체(110)의 암나사부(112)와 대응되는 숫나사부(124)가 형성되며, 상기 결합축(123)의 외주면에 고무재질로 된 원통형상의 밀폐링(125)이 설치되고, 상기 헤드부(121)의 내측에 오링(126)이 설치된다. 이때, 상기 오링(126)은 물의 누수를 전담하게 되며, 밀폐링(125)은 물의 누수를 방지함은 물론이고 약액주입공(111)의 암나사부(112)에 남아있는 방수약액을 제거하는 역할도 하게 된다.And, the opening and closing hole 120 is fixed to the head portion 121, such as a key or a key groove, so as to separate or install it using a tool (hexagon wrench, spanner, etc.) from the space maintaining tube 110. A means 122 is formed, and a male screw portion 124 corresponding to the female threaded portion 112 of the gap maintaining tube 110 is formed on a portion of the outer circumferential surface of the coupling shaft 123, and is formed on the outer circumferential surface of the coupling shaft 123. A cylindrical sealing ring 125 made of rubber material is installed, and an O-ring 126 is installed inside the head portion 121. At this time, the O-ring 126 is dedicated to the leakage of water, the sealing ring 125 serves to remove the water-resistant chemical remaining in the female threaded portion 112 of the chemical injection hole 111 as well as preventing water leakage. Will also do.
미설명 부호 300은 흙막이벽이고, 500은 토사이다.Reference numeral 300 denotes a barrier wall, and 500 denotes earth and sand.
상기와 같이 구성된 거푸집 간격유지장치(100)의 작용효과를 설명하면 다음과 같다.Referring to the effect of the formwork spacing device 100 configured as described above are as follows.
먼저, 도 5와 같이 흙막이벽(300)에 소정의 간격을 두고 내부거푸집을 설치하고, 상기 내부거푸집의 내부에 내부거푸집과 소정의 간격을 유지하면서 타설된 콘크리트의 측압을 극복할 수 있도록 거푸집 간격유지장치(100)를 여러 개소에 설치한 후 상기 거푸집 간격유지장치(100)의 각 단부를 외부거푸집과 근접되게 지지시킨 상태에서 두 거푸집 사이에 콘크리트를 타설하여 소정 두께의 콘크리트벽체 (200)을 조성하게 되는데, 이때 거푸집 간격유지장치(100)의 개폐구(120)는 콘크리트벽체 (200)내부에 완전히 매몰된다.First, as shown in FIG. 5, the inner formwork is installed at predetermined intervals on the retaining wall 300, and the formwork gap is formed so as to overcome the side pressure of the poured concrete while maintaining a predetermined gap with the inner formwork inside the inner formwork. After installing the holding device 100 in several places, the concrete wall 200 having a predetermined thickness is poured by placing concrete between the two formwork in a state in which each end of the formwork space maintaining device 100 is closely supported with the external formwork. In this case, the opening and closing hole 120 of the formwork spacing device 100 is completely embedded in the concrete wall (200).
그리고, 상기 콘크리트벽체(200)의 배면에 물의 침투를 방지할 수 있는 방수벽(400)을 시공한 다음, 상기 방수벽(400)에 방수보호층(700)을 타설하고, 흙막이벽(300)과 방수보호층(700) 사이의 공간을 양질의 토사(600)로 되메움하게 된다.Then, after constructing a waterproof wall 400 that can prevent the penetration of water on the back of the concrete wall 200, and then poured a waterproof protective layer 700 on the waterproof wall 400, the earth wall 300 And the space between the waterproof protective layer 700 is backfilled with high-quality soil 600.
상기와 같이 콘크리트벽체(200)가 완료된 상태에서 취약한 부분으로 누수가 발생하게 되면, 거푸집 간격유지장치(100)가 매설된 부분을 찾아 콘크리트벽체 (200)의 일부를 해체한 다음, 거푸집 간격유지장치(100)의 개폐구(120)에 형성된 고정.해제수단(122)에 공구를 대응시켜 이를 간격유지관체(110)로부터 분리시킨다.When the leak occurs to the vulnerable part in the state in which the concrete wall 200 is completed as described above, the formwork spacing device 100 finds the buried part and dismantles a part of the concrete wall 200, and then the formwork spacing device Corresponding to the fixing and releasing means 122 formed in the opening and closing hole 120 of 100 to separate it from the space maintaining the conduit 110.
그런 다음, 도 5와 같이 간격유지관체(110)의 약액주입공(111)에 그라우팅장치의 노즐부(500)를 삽입시켜 그 단부가 콘크리트벽체(200)의 배면에 형성된 방수벽(400)까지 근접되도록 하는데, 이때 노즐부(500)의 단부에 의해 방수벽(400)이 손상되지 않도록 그 단부가 유연한 곡면을 가지면서 측방으로 노즐공이 형성된 노즐부(500)를 체택함이 바람직하다.Then, the nozzle portion 500 of the grouting device is inserted into the chemical liquid injection hole 111 of the gap maintaining tube 110 as shown in FIG. 5 to the waterproof wall 400 formed at the rear end of the concrete wall 200. In this case, it is preferable to select the nozzle unit 500 having the nozzle hole formed laterally while the end thereof has a flexible curved surface so that the waterproof wall 400 is not damaged by the end of the nozzle unit 500.
상기와 같이 형성된 노즐부(500)를 통해 방수약액이 방출되면 콘크리트벽체 (200)와 방수벽(400)사이에 방수약액이 균일하게 퍼져 또 다른 방수벽(400')이 형성되므로서 물의 누수가 근본적으로 해결된다.When the waterproof chemical is discharged through the nozzle unit 500 formed as described above, the waterproof chemical is uniformly spread between the concrete wall 200 and the waterproof wall 400 so that another waterproof wall 400 'is formed to leak water. It is solved fundamentally.
콘크리트벽체(200)와 방수벽(400) 사이에 다른 방수벽(400')이 형성되면, 간격유지관체(110)의 약액주입공(111)에 설치된 그라우팅장치의 노즐부(500)를 분리시킨 다음, 간격유지관체(110)의 암나사부(112)에 개폐구(120)의 숫나사부(124)를 소정의 힘으로 체결하게 되는데, 이때 개폐구(120)의 밀폐링(125)이 약액주입공 (111)을 진입하면서 암나사부(112)에 잔존하고 있는 방수약액을 제거하는 동시에 방수액의 누출을 방지하게 되며, 또한 개폐구(120)의 헤드부(121)에 설치된 오링 (126)에 의해 혹시 발생할 수도 있는 물의 누수가 차단된다.When another waterproof wall 400 ′ is formed between the concrete wall 200 and the waterproof wall 400, the nozzle unit 500 of the grouting apparatus installed in the chemical liquid injection hole 111 of the gap maintaining tube 110 is separated. Next, the male threaded portion 124 of the opening and closing port 120 is fastened to the female threaded portion 112 of the gap maintaining tube 110 with a predetermined force, and at this time, the sealing ring 125 of the opening and closing hole 120 is a chemical injection hole ( While entering 111, the waterproofing chemical solution remaining in the female threaded portion 112 is removed, and at the same time, the leakage of the waterproofing liquid is prevented, and it may be caused by the O-ring 126 installed in the head portion 121 of the opening and closing hole 120. The leak of water is blocked.
따라서, 본 발명은 콘크리트벽체(200)에 매설되는 거푸집 간격유지장치 (100)를 통해 콘크리트벽체(200)의 배면으로 방수약액을 주입하여 배면전체에 방수벽(400')을 형성하므로서 콘크리트 타설 후에도 방수하자를 완벽하게 보수할 수 있도록 한 매우 유용한 효과가 있다.Therefore, the present invention injects the waterproofing chemical into the back surface of the concrete wall 200 through the formwork gap maintaining device 100 embedded in the concrete wall 200 to form a waterproof wall 400 'on the entire back surface after pouring concrete. There is a very useful effect that allows you to completely repair the waterproof flaw.
