Description

개착(開鑿)식으로 시공되는 지하철 및 공동구의 아치형 구조 및 그 시공 방법{Arch structure of subway or common duct in excavating process of constructing and method of constructing the same}Arch structure of subway or common duct in excavating process of constructing and method of constructing the same}

본 발명은 개착(開鑿)식으로 시공되는 지하철 및 공동구의 아치형 구조 및 그의 시공 방법에 관한 것이다. 보다 구체적으로는, 지하철 및 공동구의 개착식 시공에서, 구조물 단면 형상이 단순하여 이동식 동바리를 사용할 수 있고 휨모멘트가 거의 발생하지 않으며 축방향 압축력만이 작용하는 아치형 구조 및 그를 시공하는 방법에 관한 것이다.TECHNICAL FIELD The present invention relates to an arched structure of a subway and a public sphere, and a construction method thereof. More specifically, it relates to an arched structure and a method of constructing the structure of the subway and the public sphere, which has a simple cross-sectional shape, which allows the use of mobile clubs, almost no bending moment, and axial compressive force. .

통상적으로 개착식 공법은 지하 구조물이 설치되는 깊이가 약 18m 이하일 때, 터널공법보다 공사비용과 공기 면에서 유리하기 때문에 지하철 공사 및 공동구공사에서 널리 활용되고 있다. 그러나 굴착 후 축조되는 지하철 및 공동구 구조는 라멘식 박스형 구조에 한정되어 왔다. 따라서 되메우기 후 토압, 수압, 및 활하중에 의해 발생하는 휨모멘트를 지지하기 위해서 철근량을 증가시키고 헌치, 기둥 및 거더 등을 만듦으로써 구조물 내부 단면이 매우 복잡해진다. 복잡한 단면 형상에 따라, 거푸집 작업시 이동식 동바리를 사용할 수 없을 뿐 아니라 철근 배근 공정도 복잡하여 시공성이 저하되고 장기간의 공기가 요구된다. 또한, 철근량 과다로 콘크리트 타설시 골재 투입이 원할치 못하게 되어 밀실한 콘크리트 품질 확보에 어려움이 있다.In general, when the installation method is about 18m or less in the depth of the underground structure is installed, it is widely used in subway construction and joint construction because it is advantageous in terms of construction cost and air than the tunnel method. However, the construction of the subway and hollow ball structure after the excavation has been limited to the ramen box structure. Therefore, the cross section of the structure becomes very complicated by increasing the amount of reinforcing bars and creating haunches, columns and girders to support the bending moments generated by earth pressure, hydraulic pressure, and live load after backfilling. According to the complicated cross-sectional shape, not only can not use a movable copper bar when formwork, but also the rebar reinforcement process is complicated, the workability is reduced and long-term air is required. In addition, when the concrete is poured due to the excessive amount of reinforcement, it is difficult to secure tight concrete quality due to the unwanted input of aggregate.

본 발명은 휨모멘트가 거의 발생하지 않고 축방향 압축력만이 작용하는 단순한 단면의 구조를 채용함으로써 이동식 동바리를 사용할 수 있게 하여 시공성을 향상시키고 철근량 및 단면두께를 감소시켜 자재비를 절감하고 나아가 우수한 시공 품질을 제공할 수 있는 개착식으로 시공되는 지하철 및 공동구의 아치형 구조와 그의 시공 방법이다.The present invention adopts a simple cross-section structure in which bending moment is hardly generated and only axial compressive force is applied, which enables the use of movable copper clubs, thereby improving workability and reducing material costs by reducing rebar amount and cross-sectional thickness, and further improving construction quality. It is an arched structure of the subway and the public sphere that can be provided as a detachable construction and its construction method.

본 발명의 목적은 개착(開鑿)식으로 시공되는 지하철 및 공동구에서, 구조물에 휨모멘트가 거의 발생하지 않고 축방향 압축력만이 작용하게 하고 단순한 단면 형상으로 이동식 동바리를 사용 가능하게 하는 아치형 구조와 그의 시공방법을 제공하는 것이다.An object of the present invention is an arcuate structure and its arcuate structure, in which subways and hollow spheres are constructed in a detachable manner so that the bending moment is hardly generated in the structure and only the axial compressive force is applied and the movable club can be used in a simple cross-sectional shape. It is to provide a construction method.

본 발명의 구체예의 도면에 따라 설명한다.It demonstrates according to drawing of the specific example of this invention.

제1도 내지 제3도와 같이, 본 발명이 실시되는 지하 공간에 흙막이 가시설을 설치하는 과정 및 방법은 다음과 같다. 먼저 엄지말뚝(17)을 2 m 간격으로 소정 깊이까지 설치하고, 굴착작업을 진행하면서 굴착깊이가 일정 깊이에 도달할 때마다 흙막이 가시설을 설치하고 그 깊이까지의 가시설이 완성되면 다시 굴착작업을 진행하고 상기 단계를 반복하여 설계된 소정 깊이까지 굴착을 진행한다. 상기 흙막이 가시설을 구성하는 2단 수평 버팀보(13)의 수평 간격은 상기의 엄지말뚝(17)과 동일 간격인 2m 로 설치한다. 그런데 1단 및 2단 수평 버팀보 간의 설치 간격과 동일하게 2단 및 3단 수평 버팀보를 설치하게 되면, 본 발명의 아치형 구조물 지붕부(25)를 시공할 때, 상기 3단 수평 버팀보를 해체해야 한다. 그러한 경우 흙막이 벽체에서 수평 지지부재가 없는 영역이 넓어져 상기 벽체에 가해지는 토압을 지지하기가 어렵게 된다. 따라서 상기 3단 버팀보가 설치될 위치에 2단 수평 버팀보를 이용하여 수직 화타쐐기(19)를 상기 엄지말뚝(17)과 용접하여 설치하거나 상기 수직 화타쐐기(19) 대신 어스 앙카(18)를 설치한다. 상기 수직 화타쐐기(19)나 상기 어스 앙카(18)는 수평으로 가로지르는 부재가 아니므로 가시설 해체없이 상기 아치형 구조물 지붕부(25)를 시공할 수 있다.As shown in Figures 1 to 3, the process and method for installing the temporary housing in the basement space is implemented as follows. First, the thumb pile 17 is installed to a predetermined depth at intervals of 2 m, and when the excavation depth reaches a certain depth while the excavation work is carried out, the earthquake temporary facility is installed. And repeat the above steps to proceed with the excavation to the designed depth. The horizontal spacing of the two-stage horizontal braces 13 constituting the earthenware temporary installation is installed at the same distance as the thumb pile 17, 2m. However, if the two-stage and three-stage horizontal braces are installed in the same manner as the installation interval between the first and second stage braces, the three-stage horizontal braces should be dismantled when constructing the arch structure roof portion 25 of the present invention. . In such a case, the area without the horizontal support member in the retaining wall becomes wide, making it difficult to support the earth pressure applied to the wall. Therefore, by using a two-stage horizontal brace in the position where the three-stage braces will be installed by installing a vertical weeding wedge 19 with the thumb pile 17 or install an earth anchor 18 instead of the vertical weeding wedge 19. do. Since the vertical wedges 19 or the earth anchors 18 are not horizontally transverse members, the arcuate structure roof 25 may be constructed without dismantling the temporary equipment.
