Description

구조물 지하벽체로 사용가능한 흙막이벽체시스템과 그 시공방법{Retaining Wall System usable as building underground wall and its construction method}Retaining Wall System usable as building underground wall and its construction method

본 발명은 지하구조물을 구축함에 있어서 흙막이가시설을 구조물 지하벽체로 사용 가능한 흙막이벽체시스템과 그 시공방법에 관한 것으로 구체적으로는 대규모 공사현장에 적용가능한 것으로서 지하구조물 공사시 많이 사용하는 흙막이공법을 시공하여 가시설로서 활용하고 종국에는 지하구조물의 외벽으로 사용할 수 있게 하는 흙막이벽체시스템과 그 시공방법에 관한 것이다.The present invention relates to a retaining wall system and a method of constructing the retaining wall system that can use the retaining facility as a structure underground wall in constructing an underground structure, and is specifically applicable to large-scale construction sites, and constructs a retaining method that is widely used in the construction of underground structures. It relates to a retaining wall system and its construction method that can be used as a temporary facility and eventually used as an outer wall of an underground structure.

신축건물을 계획함에 있어서 지하구조물은 거의 필수적으로 만들어져야 한다. 지하구조물을 시공하기 위해서는 계획심도까지 터파기하기 위해서는 흙막이가시설을 시공하여야 한다. 흙막이가시설은 대지경계로부터 사업부지 내측으로 시공되어야 하고, 터파기를 완료한 후에는 흙막이가시설 내측에 지하구조물 본 벽체를 시공하여야 하므로 사업부지 지하공간이 흙막이가시설에 사용된 부지만큼 감소하게 된다. 이 공간은 부지의 최외측라인에 해당하기 때문에 그 감소면적은 상당히 큰 편이다.In planning a new building, underground structures must be made almost indispensably. In order to construct an underground structure, earth retaining facilities must be constructed to excavate to the planned depth. The earth retaining facility must be constructed from the site boundary to the inside of the project site, and after excavation is completed, the main wall of the underground structure must be constructed inside the earth retaining facility, so the underground space of the project site is reduced by the amount of the site used for the earth retaining facility. . Since this space corresponds to the outermost line of the site, the reduced area is quite large.

이러한 사항으로 인해 종래부터 실무자들은 흙막이가시설을 그대로 지하구조물의 본 벽체로 사용할 수 있는 방법을 강구해보고자 많은 노력을 기울여 왔으나 터파기 방법에 대한 것과 본 벽체에 배근하여야 할 철근부재 설치의 부적정과 같은 문제점에 봉착하게 되어 이 문제점을 해결하지 못해 온 것이 현실이다.Due to these issues, practitioners have been making great efforts to find out how to use the earth retaining facility as the main wall of an underground structure, but the excavation method and the inappropriate installation of reinforcing bar members to be placed on the main wall It is a reality that we have been faced with the same problem and have not been able to solve this problem.

또한, 종래에는 측면말뚝의 천공공간에서의 채움불량, 흙막이판을 설치하기 위해 측면말뚝과 측면말뚝 사이의 공간을 터파기 하는 과정에서 배면토의 이완, 여굴 발생, 여굴공간의 채움불량 등으로 배면지반이 침하하는 등의 문제가 발생하고 있다.In addition, conventionally, in the process of excavating the space between the side piles and the side piles to install the retaining board, the back ground is loosened, the overburrow occurs, and the overfill space is defective in filling the perforated space of the side piles. Problems such as subsidence occur.

또한 시간이 지남에 따라 버팀대의 압력에 의해 버팀대가 띠장을 밀게되며, 이에 따라 흙막이판재는 여굴공간으로 이동되어 배면 지반이 침하되게 된다.In addition, as time goes by, the brace pushes the wale by the pressure of the brace, and accordingly, the retaining board is moved to the over-excavation space, and the ground at the back is subsidered.

이러한 사실은 지하 굴착과정에서 주변지반의 침하를 방지하기 위해 최근 지하안전관리에 관한 특별법이 시행되고 있는 점에 역행하는 사실이어서 조속히 지하굴착과정에서의 문제점을 해소하여야 하는 대책이 요구되는 사회적 현실이 있다는 점에 있어서 특히 본 특허기술의 개발이 중요하다. 그리고 흙막이가시설을 본 구조물 벽체로 사용할 수 없을 경우에는 지하공간 활용성이 낮아지는 단점도 있는데 본 특허기술에서는 이러한 부분도 보완되게 되어 장점이 큰 기술이다.This fact runs counter to the fact that a special law on underground safety management has recently been implemented to prevent subsidence of the surrounding ground during the underground excavation process, so it is a social reality that requires countermeasures to resolve problems in the underground excavation process as soon as possible. In particular, the development of this patented technology is important. In addition, if the earth retaining facility cannot be used as the wall of the structure, there is a disadvantage that the utilization of the underground space is lowered.

한국특허등록공보 제10-1420782호 (2014.07.11)Korean Patent Registration No. 10-1420782 (2014.07.11) 한국특허등록공보 제10-1774887호 (2017.08.30)Korean Patent Registration No. 10-1774887 (2017.08.30)

본 발명의 목적은 목재가 아닌 방식처리되는 얇은 두께의 강재, 합성수지, 방부목, 콘크리트 판등을 흙막이판으로 사용함으로써 부패로 인한 지반침하의 문제 해소뿐만 아니라 흙막이판에 형성된 주입구를 통해 배면의 이완지반, 여굴부를 밀실채움할 수 있도록 하여 추후 배면지반침하의 문제를 해소할 수 있다.An object of the present invention is to solve the problem of ground subsidence due to decay by using thin steel, synthetic resin, preservative wood, concrete plate, etc., which are treated with anticorrosion instead of wood, as a retaining board, as well as to solve the problem of ground subsidence caused by decay, It is possible to solve the problem of ground subsidence in the future by allowing the overexcavation to be filled with a closed chamber.

또한, 배면지반에 소공 그라우팅을 주입하는 것 외에 터파기 과정에서 흙막이판과 측면말뚝 경계부에서 누수가 발생할 경우에 대비하여 1차적으로 흙막이판과 측면말뚝의 경계부를 용접하여 누수를 방지하도록 하고 그 누수량이 큰 경우에는 측면말뚝 배면측 플랜지 양단에 별도로 부착해둔 주입관을 통해 필요시 소정의 심도에 방수 실링재를 주입할 수 있도록 하였다. 즉, 누수, 유출수 방지를 위해 2단계에 걸친 방지대책을 수립하여 둠으로써 터파기과정에서 발생할 수 있는 누수에 의한 배면지반 지하수위 저하, 배면지반 침하를 해소할 수 있다. In addition, in addition to injecting small-hole grouting into the back ground, in case water leakage occurs at the boundary between the retaining plate and the side pile during the excavation process, the leakage is prevented by first welding the boundary between the retaining plate and the side pile, and the amount of water leakage When this is large, the waterproof sealing material can be injected to a predetermined depth if necessary through the injection pipe separately attached to both ends of the flange on the back side of the side pile. In other words, by establishing two-step prevention measures to prevent leakage and runoff, it is possible to solve the lowering of the groundwater level and the subsidence of the backing ground due to leakage that may occur during the excavation process.

본 발명에서는 이러한 점에서의 경제성 측면을 확보하기 위해 토압의 크기에 따라 적정한 측면말뚝 부재의 규격을 적용하도록 하였다. 이는 요구되는 지하구조물의 벽체 두께를 고려하여 결정할 수 있다. 또한, 흙막이판은 심도 즉 토압의 크기에 따라 그 두께를 달리하고 실제 저항부재인 판지지기구부재의 규격을 달리하여 종래의 목재 흙막이판에서와 같이 경제성을 확보할 수 있도록 하였다In the present invention, in order to secure the economic aspect in this respect, the standard of the side pile member was applied appropriately according to the size of the earth pressure. This can be determined by considering the required wall thickness of the underground structure. In addition, the thickness of the retaining board is varied according to the depth, that is, the magnitude of the earth pressure, and the standard of the cardboard support member, which is an actual resistance member, is changed to ensure economic feasibility as in the conventional wooden retaining board.

본 발명은 흙막이판 설치로 확보되는 공간이 지하구조물 설치공간으로 사용되기 때문에 지하구조물 기초매트와 흙막이판의 설치로 인해 확보되는 벽체공간을 강결하는 구조로 시공할 수 있어 흙막이판 내부공간과 측면말뚝이 일체가 되어 구조물의 지지체가 될 수 있기 때문에 흙막이판에 근접하여 시공하는 말뚝기초는 시공하지 않도록 계획할 수 있어 말뚝기초의 시공량도 감소할 수 있어 경제성 측면에서 매우 유리하다.In the present invention, since the space secured by the installation of the retaining plate is used as the installation space for the underground structure, it can be constructed with a structure that strengthens the wall space secured by the installation of the underground structure foundation mat and the retaining plate, so that the internal space of the retaining plate and the side piles Since it can become a support of the structure in one body, it is possible to plan not to construct pile foundations constructed close to the retaining board, which is very advantageous in terms of economic efficiency as the amount of construction of pile foundations can be reduced.

본 발명의 구조물 지하벽체로 사용가능한 흙막이벽체시스템과 흙막이벽체시공방법은 측면곡률말뚝(100)의 제1오목부(111)와 제2오목부(112)가 오목한 형태로 형성됨으로서 아치형흙막이판(200)이 천공장치의 케이싱이 천공시 제2천공홀(20)의 형태가 원형형태로 형성될 수 있도록 하는 이점이 있다. The retaining wall system and the retaining wall construction method that can be used as a structure underground wall of the present invention are arched retaining plates ( 200) has the advantage of allowing the second drilling hole 20 to be formed in a circular shape when the casing of the drilling device is drilled.

본 발명은 목재가 아닌 방식처리되는 얇은 두께의 강재, 합성수지, 방부목, 콘크리트판 등을 흙막이판으로 사용함으로써 부패로 인한 지반침하의 문제 해소뿐만 아니라 흙막이판재에 형성된 주입구를 통해 배면의 이완지반, 여굴부를 밀실채움할 수 있도록 하여 추후 배면지반침하의 문제를 해소할 수 있다.The present invention solves the problem of ground subsidence due to decay by using thin steel, synthetic resin, antiseptic wood, concrete plate, etc., which are treated with anticorrosion instead of wood, as a retaining board, and also solves the problem of ground subsidence due to decay, and also solves the problem of ground subsidence through the injection hole formed in the retaining plate It is possible to solve the problem of subsidence of the back ground in the future by allowing the wealth to be filled with a closed room.

또한, 배면지반에 소공 그라우팅을 주입하는 것 외에 터파기 과정에서 흙막이판재와 측면말뚝 경계부에서 누수가 발생할 경우에 대비하여 1차적으로 흙막이판재와 측면말뚝의 경계부를 용접하여 누수를 방지하도록 하고 그 누수량이 큰 경우에는 측면말뚝 배면측 플랜지 양단에 별도로 부착해둔 주입관을 통해 필요시 소정의 심도에 방수 실링재를 주입할 수 있도록 하였다. 즉, 누수, 유출수 방지를 위해 2단계에 걸친 방지대책을 수립하여 둠으로써 터파기과정에서 발생할 수 있는 누수에 의한 배면지반 지하수위 저하, 배면지반 침하를 해소할 수 있다. In addition, in addition to injecting small hole grouting into the back ground, in case water leakage occurs at the boundary between the retaining board and the side pile during the excavation process, the leakage is prevented by welding the boundary between the retaining board and the side pile first, and the amount of water leakage When this is large, the waterproof sealing material can be injected to a predetermined depth if necessary through the injection pipe separately attached to both ends of the flange on the back side of the side pile. In other words, by establishing two-step prevention measures to prevent leakage and runoff, it is possible to solve the lowering of the groundwater level and the subsidence of the backing ground due to leakage that may occur during the excavation process.

본 발명에서는 이러한 점에서의 경제성 측면을 확보하기 위해 토압의 크기에 따라 적정한 측면말뚝 부재의 규격을 적용하도록 하였다. 이는 요구되는 지하구조물의 벽체 두께를 고려하여 결정할 수 있다. 또한, 흙막이판재는 심도에 따라 그 두께를 달리하고 실제 저항부재인 판지지기구부재의 규격을 달리하여 종래의 목재 흙막이판에서와 같이 경제성을 확보할 수 있도록 하였다.In the present invention, in order to secure the economic aspect in this respect, the standard of the side pile member was applied appropriately according to the size of the earth pressure. This can be determined by considering the required wall thickness of the underground structure. In addition, the retaining board material has a different thickness according to the depth and the standard of the paperboard support member, which is an actual resistance member, is changed to secure economic feasibility as in the conventional wooden retaining board.

본 발명은 흙막이판 설치로 확보되는 공간이 지하구조물 설치공간으로 사용되기 때문에 지하구조물 기초매트와 흙막이판의 설치로 인해 확보되는 벽체공간을 강결하는 구조로 시공할 수 있어 흙막이판 내부공간과 측면말뚝이 일체가 되어 구조물의 지지체가 될 수 있기 때문에 흙막이판에 근접하여 시공하는 말뚝기초는 시공하지 않도록 계획할 수 있어 말뚝기초의 시공량도 감소할 수 있어 경제성 측면에서 매우 유리하다.In the present invention, since the space secured by the installation of the retaining plate is used as the installation space for the underground structure, it can be constructed with a structure that strengthens the wall space secured by the installation of the underground structure foundation mat and the retaining plate, so that the internal space of the retaining plate and the side piles Since it can become a support of the structure in one body, it is possible to plan not to construct pile foundations constructed close to the retaining board, which is very advantageous in terms of economic efficiency as the amount of construction of pile foundations can be reduced.
