Description
본 발명은 지상과 터널 및 타설 현장에서 레미콘을 이송하고 타설작업을 수행하는 주체를 각각 분화시켜 전문화함으로써 작업 효율을 높인 터널 내의 콘크리트도상 거푸집에 레미콘을 타설하는 방법에 관한 것이다.The present invention relates to a method for placing a ready-mixed concrete concrete formwork in a tunnel in which the work efficiency is improved by differentiating and specializing the subjects carrying the ready-mixed concrete and transporting the ready-mixed concrete at the ground, the tunnel, and the site of the placing.
일반적으로 궤도는 노반과, 도상, 침목 및 레일을 포함하는 구성으로 이루어진다. 여기서 상기 도상은 철도차량의 운행에 따른 충격과 진동을 흡수하기 위한 것으로 전통적으로는 자갈도상으로 형성되었으나, 자갈도상은 오랜 시간이 흐름에 따라 유실되거나 침하되는 문제가 있어서, 최근에는 도시 철도나 터널 및 협소 공간, 침하가 많은 곳 등에서 콘크리트도상으로 대체되어 시공되고 있다.In general, the track consists of a roadbed, an image, a sleeper and a rail. Here, the figure is to absorb the shock and vibration caused by the operation of the railway vehicle, traditionally formed as a gravel phase, the gravel phase is a problem that is lost or settled with the passage of a long time, in recent years urban railway or tunnel And it is being replaced by concrete in many places, such as narrow space, sinking.
이러한 콘크리트도상을 채택한 궤도를 터널에 시공할 경우에는 콘크리트 생산공장에서 제조된 레미콘(Ready Mixed Concrete)을 믹서트럭을 이용하여 빠른 시간내에 운송한 후 터널 내측의 타설지점의 거푸집에 믹서트럭이 직접 타설하게 된다. 그런데, 철도차량을 위한 터널은 일반적으로 산간지역이나 지하 수십미터 아래에 형성되는 경우가 많으므로 터널 시공 현장까지 믹서트럭이 직접 접근하는 문제가 용이하지 않으며, 운송을 위한 우회도로 또한 멀리 돌아가는 경우가 많으므로 믹서트럭의 운송시간이 지연되기 마련이다. 뿐만 아니라 터널 내에서는 차량이 한대씩 직접 들어가 타설해야 하므로 타설시간 동안에는 많은 믹서트럭이 터널 입구에서 대기하는 경우가 발생하게 된다.In the case of constructing the track using the concrete phase in the tunnel, the ready mixed concrete manufactured by the concrete production plant is transported by using the mixer truck in a short time, and then the mixer truck is directly placed in the formwork at the place of pouring inside the tunnel. Done. However, since tunnels for railroad cars are generally formed in mountainous areas or several tens of meters below the ground, it is not easy for the mixer truck to directly access the tunnel construction site, and the bypass road for transportation is also far away. In many cases, the truck's transportation time is delayed. In addition, in the tunnel, many vehicles have to enter and cast one by one.
그런데, 레미콘은 시멘트와 물의 수화반응이 일어나기 전에 타설까지의 모든 공정을 완료해야 하고, 타설시에는 한 구획내의 치기가 완료될 때까지 중단없이 연속해서 쳐야 하는데, 상기한 문제들 때문에 현장에서 레미콘 타설을 할 때에는 많은 수의 장비와 인력이 동원되고 치밀한 배차계획을 수립해야하는 등 세심한 주의가 필요하며, 타설 현장에서 자칫 서두르거나 믹서트럭의 배차시간이 맞지 않을 경우에는 부실시공이 이루어지게 되는 문제가 있다.By the way, the ready-mixed concrete must be completed before the hydration reaction between cement and water, and when it is poured, it must be continuously stroked without stopping until the stroke in one compartment is completed. In this process, a great deal of equipment and manpower is required, and a detailed dispatch plan is required, and there is a problem in that the construction work is carried out in case of rushing at the casting site or when the truck's dispatch time is not correct. .
본 발명은 상기한 문제를 감안하여 창출된 것으로, 지상과 터널 및 타설 현장에서 레미콘을 이송하고 타설작업을 수행하는 주체를 각각 분화시켜 전문화함으로써 작업 효율을 높인 터널의 콘크리트도상 거푸집에 레미콘을 타설하는 방법을 제공함에 그 목적이 있다.The present invention has been made in view of the above-mentioned problems, specializing by transferring the ready-mixed concrete at the ground, tunnel and pour site and performing the pouring work, respectively, to lay the ready-mixed concrete concrete formwork in the tunnel of the work efficiency The purpose is to provide a method.
상기의 목적을 달성하기 위한 본 발명은, 레미콘을 제조공장에서부터 터널 내로 운반한 후 콘크리트도상 거푸집에 타설하기 위한 방법에 있어서, 콘크리트 펌프카를 이용하여 지상에서 터널 입구까지 레미콘을 이송하고, 믹서트럭을 이용하여 터널 내의 타설 현장까지 수송하며, 타설 현장에서는 레미콘을 호퍼에 일시 저장한 후 타설 작업을 수행하는 방법으로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, in the method for placing the ready-mixed concrete in the tunnel after transporting the ready-mixed concrete from the manufacturing plant, using a concrete pump car to transport the ready-mixed concrete from the ground to the entrance of the tunnel, It is used to transport to the pour site in the tunnel, the pour site is characterized in that made of a method of performing the pouring work after temporarily storing the ready-mixed concrete in the hopper.

Details are as follows.
먼저, 도 1에서 도시하는 바와 같이 도로 등을 이용하여 현장까지 가장 접근하기 쉬운 현장 주변지점에는 긴 파이프라인(21)이 구비된 공지의 콘크리트 펌프카(20)가 배치되며, 콘크리트 제조공장에서 제조된 레미콘을 믹서트럭(10)을 이용하여 상기 콘크리트 펌프카(20)에 지속적으로 공급하게 된다. 그러므로 본 발명에서 상기 믹서트럭(10)은 운송이 쉬운 도로상을 왕복 이동하게 되므로 공장에서 제조된 레미콘을 신속하게 콘크리트 펌프카(20)에 공급할 수 있다.First, as shown in FIG. 1, a well-known concrete pump car 20 having a long pipeline 21 is disposed at a site around a site that is most accessible to a site using a road or the like, and is manufactured in a concrete manufacturing plant. The ready-mixed concrete is continuously supplied to the concrete pump car 20 using the mixer truck 10. Therefore, in the present invention, since the mixer truck 10 is reciprocated on the road for easy transportation, the ready-mixed concrete ready-to-use can be quickly supplied to the concrete pump car 20.
그리고 터널(70) 입구에는 상기 믹서트럭(10)과는 다른 믹서트럭(30)이 대기되며, 상기 믹서트럭(10)으로부터 레미콘을 공급받은 콘크리트 펌프카(20)는 긴 파이프라인(21)을 통하여 터널(70) 입구에 대기된 다른 믹스트럭(30)에 레미콘을 공급하게 된다. 이와 같이 본 발명에서는 운송속도가 느리고 멀리 우회하여 가설된 종래의 비포장 가설도로 운송 구간을 직선 배치된 파이프라인(21)으로 대체함으로써 레미콘의 운송 시간을 획기적으로 단축하게 된다.In addition, a mixer truck 30 different from the mixer truck 10 is waiting at the entrance of the tunnel 70, and the concrete pump car 20 supplied with the ready mixed concrete from the mixer truck 10 is connected to the long pipeline 21. The ready-mixed concrete is supplied to another mix truck 30 waiting at the entrance of the tunnel 70. As described above, in the present invention, the transportation time of the ready-mixed concrete is dramatically shortened by replacing the transportation section with a pipeline 21 arranged in a straight road, which is a conventional unpaved construction road that is hypothetically circumvented.
다음으로 터널(70) 내측의 타설 현장에는 호퍼(40)가 구비되며, 상기 콘크리트 펌프카(20)로부터 레미콘을 공급받은 믹서트럭(30)이 터널(70) 내측으로 이동하여 타설 현장에 구비된 호퍼(40)에 레미콘을 공급하게 된다. 이와 같이 호퍼(40)에 레미콘을 공급한 믹서트럭(30)은 터널(70) 입구로 다시 이동하여 콘크리트 펌프카(20)로부터 레미콘을 재공급받은 후 상기한 과정을 반복하게 된다.Next, a hopper 40 is provided at the pouring site inside the tunnel 70, and the mixer truck 30 supplied with the ready mixed concrete from the concrete pump car 20 moves to the inside of the tunnel 70 to provide a hopper. The ready-mixed concrete is supplied to 40. In this way, the mixer truck 30, which supplies ready-mixed concrete to the hopper 40, moves back to the inlet of the tunnel 70 to receive the ready-mixed concrete from the concrete pump car 20, and then repeats the above process.
한편, 상기 과정에서 사용되는 호퍼(40)는 도 3에서 도시하는 바와 같이 저장탱크(41)와 배출구(42)와 개폐레버(43) 및 가이드(44)를 포함하는 구성으로 이루어진다. 여기서 상기 저장탱크(41)는 상부가 개방되고 하부가 깔대기 처럼 형성되어 레미콘을 저장하는 역할을 하게 되고, 상기 배출구(42)는 상기 저장탱크(41)의 최하부에 형성되며, 상기 개폐레버(43)는 상기 배출구(42) 통로를 외부에서 쉽게 개폐할 수 있게 형성된다. 그리고 상기 가이드(44)는 'U'자형 단면을 가진 공지 구성으로 이루어져 상기 배출구(42) 단부에서 회동가능하게 결합되며, 상기 배출구(42)를 통해 배출되는 레미콘을 정확한 타설지점으로 안내하는 역할을 하게 된다.On the other hand, the hopper 40 used in the above process consists of a configuration including a storage tank 41, the outlet 42, the opening and closing lever 43 and the guide 44 as shown in FIG. Here, the storage tank 41 is open at the top and the bottom thereof is formed as a funnel to serve to store ready-mixed concrete, and the outlet 42 is formed at the bottom of the storage tank 41, and the opening and closing lever 43 ) Is formed to easily open and close the passage 42 from the outside. And the guide 44 is made of a known configuration having a 'U' shaped cross-section is rotatably coupled at the end of the outlet 42, and serves to guide the ready-mixed concrete discharged through the outlet 42 to the exact place of pouring. Done.
마지막으로 도 3에서 도시하는 바와 같이 터널(70) 입구에 구비된 믹서트럭(30)으로부터 레미콘을 공급받은 호퍼(40)는 상기 저장탱크(41)에 레미콘을 일시 저장하게되며, 타설작업시에는 타설작업방향으로 진행하면서 레미콘을 거푸집(50)에 타설하게 된다. 이와 같이 본 발명에서는 현장에서 레미콘을 일시 저장한 후 타설작업을 수행할 수 있는 호퍼(40)가 구비됨으로써, 타설현장에서의 타설작업을 종래보다 한층 여유로운 분위기에서 수행할 수 있어서 좀더 정확한 시공을 할 수 있으며, 타설작업 중에도 레미콘을 공급받을 수 있어 긴 구간도 연속적으로 타설할 수 있게 된다. 한편, 상기 호퍼(40)의 저장탱크(41)에 일시저장된 레미콘은 공지의 콘크리트 진동기(미도시)를 이용하여 주기적으로 진동시켜 수화를 방지하는 것이 바람직하다.Finally, as shown in FIG. 3, when the ready-mixer is supplied from the mixer truck 30 provided at the entrance of the tunnel 70, the hopper 40 temporarily stores the ready-mixed concrete in the storage tank 41. The concrete ready to be poured into the formwork 50 while proceeding in the pouring operation direction. As described above, the present invention is provided with a hopper 40 capable of performing the pouring work after temporarily storing the ready-mixed concrete in the field, so that the pouring work in the pouring site can be performed in a more relaxed atmosphere than before, so that more accurate construction can be performed. It can be supplied with ready-mixed concrete during pouring work, so that long sections can be poured continuously. On the other hand, the ready-mixed concrete ready to be stored in the storage tank 41 of the hopper 40 is preferably vibrated using a known concrete vibrator (not shown) to prevent hydration.
한편, 터널(70)에 복선궤도가 시공될 경우에는 시공하고자 하는 궤도외에도터널(70)에 가설되거나 기설된 궤도(60)가 있는데, 이 경우에는 도 1 및 도 3에서 도시하는 바와 같이 상기 믹서트럭(30)과 호퍼(40)는 상기 궤도(60) 상에 구비된 화차(61, 62)에 별도로 각각 탑재되어 이동하게 된다. 반면, 터널(70)에 아직 가설되거나 기설된 궤도가 없거나, 단선궤도만 시공될 경우에는 상기 호퍼(40)는 별도로 구비되는 트럭(미도시)에 탑재되어 이동하게 된다. 물론, 상기 믹서트럭(30)은 단독으로 터널(70) 입구와 호퍼(40) 사이를 이동하게 된다.On the other hand, when a double track orbit is constructed in the tunnel 70, there is a track 60 installed or established in the tunnel 70 in addition to the track to be constructed. In this case, the mixer as shown in FIGS. 1 and 3. The truck 30 and the hopper 40 are separately mounted on the wagons 61 and 62 provided on the track 60 to move. On the other hand, when there is no track or construction already established in the tunnel 70, or if only a single track is constructed, the hopper 40 is mounted on a truck (not shown) that is separately provided to move. Of course, the mixer truck 30 alone moves between the entrance of the tunnel 70 and the hopper 40.
상기와 같은 방법으로 구성된 본 발명에 의한 레미콘 타설 방법으로 시공하게 되면, 콘크리트 제조공장에서 제조된 레미콘을 이송하는 과정이 도로운송구간과, 파이프라인 운송구간 및 터널 내 운송구간으로 분화되고, 각 운송구간 별로 최상의 상태에서 운송과정을 반복하게 되므로 믹서트럭만으로 모든 운송구간을 운송하였던 종래에 비해 레미콘 운송효율이 훨씬 높으며, 많은 믹서트럭이 동원되어야만 했던 종래에 비해 연투입 장비 및 인력수를 훨씬 감소시킬 수 있어 경제적이다.When the construction of the ready-mixed concrete placing method according to the present invention constituted as described above, the process of transporting the ready-mixed concrete prepared in the concrete manufacturing plant is differentiated into a road transport section, a pipeline transport section and a transport section in the tunnel, and each transport Since the transportation process is repeated in the best condition for each section, the efficiency of ready-mixed concrete transportation is much higher than that of the conventional transporting all transportation sections using only the mixer truck, and the number of annual input equipment and manpower is much reduced compared to the conventional method, in which many mixer trucks had to be mobilized. It is economical.
또한 본 발명에 의한 레미콘 타설 방법으로 시공하게 되면, 터널(70) 내의 타설현장에서 호퍼(40)가 레미콘을 일시 저장한 후 현장상황에 따라 여유롭게 시공할 수 있으므로 종래에 비해 정확게 시공할 수 있으며, 타설현장에서 호퍼(40)가 타설하고 있는 동안에도 믹서트럭이 터널(70) 입구에서 장기대기하지 않고 레미콘 운송작업을 계속할 수 있어 종래보다 작업효율이 훨씬 향상된다.In addition, when the construction by the method of placing the ready-mixed concrete according to the present invention, since the hopper 40 temporarily stores the ready-mixed concrete at the pouring site in the tunnel 70, the construction can be performed comfortably according to the site situation. In addition, while the hopper 40 is being poured at the pouring site, the mixer truck can continue to transport the ready-mixed concrete without waiting for a long time at the entrance of the tunnel 70, thereby improving work efficiency.
상기와 같은 방법의 본 발명은 비단 터널 내의 궤도 부설 뿐만 아니라, 터널 내의 다른 유사한 레미콘 시공방법에 모두 적용하여 사용할 수 있다.The present invention of the method as described above can be applied to not only laying the track in the silk tunnel, but also applied to all other similar ready-mixed concrete construction method in the tunnel.
이상의 설명과 같이 본 발명은 종래에 비해 운송효율 및 작업효율이 높아 공기를 단축시킬 수 있고, 연투입 장비 및 인력수가 감소되어 공사비용이 절감되며, 터널(70) 내의 타설현장에서는 호퍼(40)가 레미콘을 저장한 후 타설작업을 단독적으로 수행하게 되므로 종래보다 여유롭고 정확하게 시공할 수 있는 효과가 있다.As described above, the present invention has a higher transportation efficiency and a higher working efficiency than the conventional art, and thus shortens the air, and reduces the construction cost by reducing the number of annual input equipment and manpower, and the hopper 40 in the pouring site in the tunnel 70. After saving the ready-mixed concrete is performed by the pouring work alone, there is an effect that can be installed more relaxed and accurate than the conventional.
