Description
본 고안은 도로 또는 지하철의 터널시공시 터널의 내부를 지지하기 위해 시공되는 격자지 보재의 받침부를 높이조절이 가능하도록 간편하게 연결함으로써, 시공성을 향상시켜 시공비를 절감시켜 줌과 동시에 시공시 작업자의 안전성을 보장하여 주는 격자지 보재의 높이조절 연결장치에 관한 것이다.The present invention can be easily connected to support the height of the grid support to be installed to support the inside of the tunnel when the tunnel construction of the road or subway, to improve the construction properties to reduce the construction cost and at the same time the safety of workers The present invention relates to a height control connecting device of the lattice base material which ensures the safety.
일반적으로, 일반적으로 터널을 시공할 때 터널의 입구측에서부터 암반 및 토사를 굴진시키면서 격자지보재(Lattice Girder)를 순차적으로 입설시키고 격자지보재를 지지하기 위하여 다수의 간격지지구를 격자지보재와 격자지보재 사이에 고정설치하여 격자지보재를 지지시키고 터널 굴진공사가 종료되면 간격지지구로 지지된 격자지보재에 쇼크리트(Shocrete)를 타설시켜 일차적인 터널공사를 완료시키는 것이다.In general, when constructing a tunnel, a plurality of interval supports are interposed between lattice supports and lattice supports to sequentially insert lattice girders and support lattice supports while excavating rock and soil from the entrance side of the tunnel. It is fixedly installed in the lattice supporting material, and when the tunnel excavation is completed, the shovelte is poured into the lattice supporting material supported by the gap support to complete the primary tunnel construction.
그러나, 상기의 격자지보재는 굴착작업시 암반의 특성상 발생되는 과다굴착으로 인해 격자지보재의 하부가 굴착된 지면과의 밀착성이 떨어져 이격이 발생되며, 상기 이격된 공간을 매우기 위해 숏크리트를 타설하게 되는데, 이는 숏크리트타설 비용이 증가 됨은 물론 불필요한 공정이 발행하여 작업진행이 속도가 현저히 늦어지는 문제점이 있었다.However, the lattice support material is spaced apart due to the excessive excavation generated due to the characteristics of the rock during the excavation work due to the lack of adhesion to the ground surface is excavated, and the shotcrete is poured in order to make the space spaced apart. This, in turn, increases the cost of shotcreting, as well as an unnecessary process issue, resulting in significantly slower work progress.
이러한 문제점을 개선하기 위해 격자지보재의 하부에 지지부재가 장착된 받침판을 결합하여 지면과 밀착시키게 되었지만 이 또한, 시방규정에 지보재의 높낮이 조절 후 용접 이음부가 100mm 이상이 되도록 규정하고 있으므로, 설치작업시 격자지보재를 공중에 매단 후 격자지보재의 연결부에 대한 용접작업이 이루어져야 하므로 많은 시간이 소요될 뿐만 이니라 작업중 안전사고가 발생될 수 있는 문제가 상존하게 되는 것이다.In order to improve this problem, the support plate mounted on the lower part of the grid support is combined with the ground, but it is also in close contact with the ground after adjusting the height of the support. Since the lattice retainer is suspended in the air and welded to the connection part of the lattice retainer must be made, it takes a lot of time and there is a problem that a safety accident may occur during the work.
따라서, 본 고안은 종래 주입호스 및 에어호스의 사용에 따른 제반적인 문제점을 해결하고자 창안된 것으로;Therefore, the present invention has been devised to solve the general problems caused by the use of the conventional injection hose and air hose;
