The equipment is installed by caterpillars mounted on both sides as a tunnel excavation device having a larger internal area than the existing tunnel outer surface. While moving, the inside of the equipment is moved to the space by wrapping it over the existing tunnel using the existing excavation device, and then expanding the tunnel by the usual construction methods such as the continuous column wall method, the underground continuous wall method, and the ground reinforcement method. After the reinforcement work is completed along the contour, the expansion tunnel construction is completed by excavating the predetermined position of the expansion tunnel, and then the caterpillar, such as the caterpillar of the tunnel excavator, is mounted on both sides, and the upper part of the equipment, such as the excavator, which is empty inside Instead of removing the excavators and supports mounted on the roof, they are covered with a hemispherical roof. Caterpillar moves the protective equipment with less outer surface into the existing tunnel to dismantle the existing tunnel while continuing the operation of the vehicle within the demolition equipment. It is characteristic to make it possible.

And a tunnel-shaped support body 101 having an inner space 105 at the center thereof, a pair of caterpillars 103 mounted on both side lower ends 102 and moving thereon, and the support body 101 of the support body 101. A pair of domed auxiliary supports 106 mounted before and after the top and a pair of perforated rods 109 for transporting and supporting 108 for mounting the perforated rod 109 connected by the auxiliary supports and the plurality of connecting rods 107, and both The expansion cylinder 116 is vertically stretched up and down by hydraulic pressure at the lower end of the perforated rod mounting boom 113 is built in the pinion 111 which is engaged with the groove-type rack 110 formed on the side of the boom feed and support 108. Connected bracket 112 and the bracket 112 is moved It is composed of a hydraulic device 114 to be registered using the existing tunnel excavation device 4, such as a detailed perspective view shown in Figure 4, the first application, registered in the registration number 10-0402336, but the central internal space 105 Excavator is used to cover the existing tunnel 1 in the inner space 105 of the tunnel excavator 4 by using the tunnel excavator 4 that is wider than the outer surface 12 of the existing tunnel 1. After excavating the expansion scheduled tunnel (5) by the excavation method using the existing tunnel drilling device (4) while moving by the caterpillar 103, as shown in the detailed perspective view shown in Figure 5, the inner space 105a A support body (101a) having a pair, a pair of caterpillars (103a) mounted on both side lower ends (102a) and moving it, a pair of domed auxiliary supports (106a) mounted before and after an upper end of the support body (101a), and the A plurality of connecting rods (107a) connected to the auxiliary support and the existing tunnel drilling device (4) The vehicle and personnel protection equipment 9 consisting of a plurality of connecting rods (107a) is equipped with a hemispherical roof (8) having an outer surface smaller than the interior (13) of the existing tunnel (1) to the existing tunnel (1) It is located inside the tunnel to protect the tunnel demolition from falling to the tunnel floor, and then the existing tunnel (1) is an extension tunnel construction method consisting of dismantling by the normal demolition method.

미설명부호 104는 높이조절잭이고 115는 장치기판이다.상기 터널천공장치(4)는 상기한 기존의 선등록된 터널천공장치와 동일하지만 장치의 내부공간(105)이 기존 터널(1)의 외표면(12)넓이보다 더 넓어서 기존 터널(1)을 외부에서 감싸면서 터널내로 캐터필러(103)에 의해 이동시켜 굴착작업을 할 수 있고 그 굴착작업을 하는 동안 장치를 이동할 필요없이 장치의 중앙에 확보된 공간(105)을 통하여 터널내로 차량과 인원의 출입이 항상 가능하므로 굴착작업을 중단없이 계속할 수 있고 천공롯드(109)는 붐(113) 하단에서 유압에 의해서 상하 신축되는 신축 실린더(116)에 연결된 브라켓(112)에 내장된 피니언(111)이 홈형 랙(110)과 맞물려서 유압장치(114)에 의해 이송겸 지지대(108)위를 선회하므로 어떤 위치에서도 천공롯드의 이송이 가능하며 높이조절도 실린더(116)에의해 자유자재로 할 수가 있어서 굴착작업이 용이한 장점이 있다.Reference numeral 104 is a height adjustment jack and 115 is a device substrate. The tunnel drilling device 4 is the same as the existing pre-registered tunnel drilling device described above, but the internal space 105 of the device is the same as that of the existing tunnel 1. It is wider than the outer surface 12 so that the existing tunnel 1 can be wrapped outside and moved by the caterpillar 103 into the tunnel for excavation work, and the center of the device can be moved without having to move the device during the excavation work. Through the secured space 105, the entry and exit of vehicles and personnel is always possible, so the excavation work can be continued without interruption, and the drilling rod 109 is stretched up and down by hydraulic pressure at the bottom of the boom 113. The expansion cylinder 116 The pinion 111 built in the bracket 112 connected to the grooved rack 110 is engaged with the pivoting unit 108 by the hydraulic device 114 so that the feed rod can be transported at any position and the height can be adjusted. On cylinder 116 There is an advantage that the excavation work can be easily made freely.

본 발명에서 사용된 지반보강 공법으로는 주열식 연속벽공법(도1 및 2참조)을 사용하였다.또한 확장터널의 굴착작업이 끝나면, 기존 터널(1)의 내부크기보다 외경이 작은 반구형 지붕(8)을 가진, 도5에 도시된 바와같은, 방호장비(9)를 캐터필러(103a)로 이동시켜 기존 터널(1)내부에 설치하여 반구형의 외표면 지붕(8)에의해 철거시 낙하되는 철거폐기물이 터널내 바닥중앙으로 낙하되지 못하도록하므로써 방호장비(9)내로는 사람과 차량이 철거작업중에도 출입할 수 있게 되는 것이다.이에 철거방법은 기존 이용되는 철거방법에 의해 철거하게 된다.As the ground reinforcement method used in the present invention, a column-heated continuous wall method (see FIGS. 1 and 2) was used. After the excavation work of the expansion tunnel, a hemispherical roof having a smaller outer diameter than the inner size of the existing tunnel 1 5, the demolition of the protective equipment (9), as shown in Figure 5, moved to the caterpillar (103a) and installed in the existing tunnel (1) to be dropped during demolition by the hemispherical outer surface roof (8) By preventing waste from falling down to the center of the floor in the tunnel, people and vehicles can enter and exit the protective equipment 9 during the demolition work. The demolition method is demolished by the existing demolition method.

이상과 같이 구성되는 본 발명 확장터널시공방법으로 터널을 확장하게되면 기존 터널내로 차량 통행이 가능하게 현상태로 둔채 그 기존 터널(1)을 감싸는 터널굴착장치(4)로 확장 예정터널을 굴착시공할 수 있는 장점이 있고 따라서 다른 지역에 터널공사를 별도로 하기위해 부지 확보를 할 필요가 없고 별도 용지, 주택, 도로등의 보상이나 시설이 필요없으므로 막대한 예산을 절감할 수 있고 인건비, 장비 및 시공 시간의 절감으로 시공비가 현저하게 절감되는 효과도 있게 된다.When the tunnel is expanded by the present invention, the tunnel construction method as described above can be used to excavate the tunnel to be extended to the tunnel excavation device (4) surrounding the existing tunnel (1) while leaving the vehicle in an existing state to enable traffic. There is an advantage in that it is not necessary to secure the site to separate the tunnel construction in other areas, and there is no need for compensation or facilities such as site, house, road, etc., which can save enormous budget and reduce labor cost, equipment and construction time. In addition, construction costs are significantly reduced.

뿐만 아니라 확장터널 공사가 완료된 후에 기존 터널의 철거도 기존 터널의 크기보다 작은 철거용 방호장비(9)를 기존 터널(1)내에 위치시켜 철거하게되면 터널내로 차량 통행이 유지되면서 철거를 할 수 있고 먼지나 소음이 적게되어 철거작업이 가능하고 단시간에 효과적으로 철거할 수 있는 장점도 있는 것이다.In addition, after the completion of the extension tunnel construction, the demolition of the existing tunnel is also carried out by placing the demolition protective equipment (9) smaller than the size of the existing tunnel in the existing tunnel (1). Less dust and noise is possible to remove the work and there is an advantage that can be effectively removed in a short time.
