도로용 터널 공동구의 덮개 구조{Cover Structure of Utility Tunnel for Road Tunnel}Cover Structure of Utility Tunnel for Road Tunnel

본 발명은 도로용 터널 공동구의 덮개 구조에 관한 것으로, 더욱 상세하게는 터널 공동구용 덮개의 개폐를 용이하게 할 수 있도록 한 도로용 터널 공동구의 덮개 구조에 관한 것이다.The present invention relates to a cover structure of a road tunnel cavity, and more particularly, to a cover structure of a road tunnel cavity to facilitate opening and closing of a cover for a tunnel cavity.

일반적으로 터널의 가장자리에는 도로 포장면보다 약간 올라오도록 시공된 공동구가 있는데, 이러한 공동구에는 전선보호관, 소화전, 배수관, 전선관, 통신관 등 터널 및 도로의 유지관리에 필요한 시설물들을 하나의 공간에 공동으로 수용하도록 함으로써 터널의 보전 및 교통 소통을 원활하게 하고 있다.Generally, at the edge of the tunnel, there is a cavity that is constructed to rise slightly above the pavement, and such a cavity is used to jointly accommodate the facilities necessary for the maintenance of the tunnel and the road, such as electric wire protectors, fire hydrants, drain pipes, conduits, and communication pipes. By doing so, tunnel maintenance and traffic communication are smooth.

즉, 터널 내에는 터널내부의 조명, 환풍시설, 감시시설 등의 전기시설과 터널내로 유입되는 우수나 지하수의 배수를 위한 배수시설, 각종 정보를 전달하는 통신시설, 터널내 화재 등에 대비한 소화전 시설 등 각종 설비들이 설치되어 있고, 이들의 효율적인 관리와 원활한 사용을 위해 공동구를 설치하게 된다.In other words, in the tunnel, electric facilities such as lighting inside the tunnel, ventilation facilities, and monitoring facilities, drainage facilities for drainage of rainwater or groundwater flowing into the tunnel, communication facilities for transmitting various information, and fire hydrant facilities for fires in tunnels Various facilities are installed, and common areas are installed for their efficient management and smooth use.

이와 같은 공동구가 구비되지 않고 개별적으로 땅을 파서 설치한다면 각각의 시설에 문제가 발생될 경우 터널을 차단하고 굴착할 때 교통소통에 문제가 생기지만 공동구를 설치하면 공동구 덮개를 열어 보수만 하면 되므로 아주 효율적인 터널의 유지관리가 가능하게 되고, 동시에 교통소통에 방해되지 않게 작업할 수 있게 된다. If you do not have such a communal hole and install it by digging individually, if there is a problem in each facility, there will be a problem in traffic communication when the tunnel is blocked and excavated. Efficient tunnel maintenance is possible, while at the same time working without disrupting traffic.

여기서 공동구 덮개는 공동구 내의 매설물이 손상되거나 파손되는 것을 방지하고자 외부로부터 이물질 등이 유입되지 않도록 밀폐성을 가지도록 덮이게 되며, 짐은 물론 점검자 등이 통행할 때 하중에 대하여 충분히 견딜 수 있도록 대부분 콘크리트로 제작되고 있으며, 콘크리트로 만들어진 덮개는 경제성이 우수하고 내화성을 지니고 있어 화재에도 안전하게 된다.Here, the cover of the joint hole is covered to have a sealing property to prevent foreign matters from entering the outside in order to prevent damage to or damage to the buried material in the cavity, and most of the concrete is made of concrete so that the load can be sufficiently endured when the inspector passes. Made of concrete, the cover made of concrete is economical and fire resistant, making it safe from fire.

도면 중 미설명 부호 95는 견인로프(70) 끝에 설치된 후크를 나타낸 것이다.In the figure, reference numeral 95 denotes a hook installed at the end of the towing rope 70.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도2 내지 도8에 도시된 바와 같이 터널공동구(20)가 덮개(30)에 의해 닫혀진 상태에서 이를 개방하는 경우 견인로프(70) 끝에 달린 후크(95)를 굽힘손잡이(40)에 걸고, 견인로프(70)를 롤러(80)에 걸어서 팽팽하게 당기게 되면, 덮개(30)가 힌지핀(32)을 기점으로 회전하여 개방된다.As shown in FIGS. 2 to 8, when the tunnel hole 20 is opened while the tunnel hole 20 is closed by the cover 30, the hook 95 attached to the end of the towing rope 70 is hooked to the bending handle 40. When the pulling rope 70 is pulled taut by the roller 80, the cover 30 is opened by rotating the hinge pin 32 as a starting point.

이때 견인로프(70)를 잡아당기는 것을 인력으로도 할 수 있지만 윈치(winch)나 레바블럭(lever block) 등과 같은 기계적인 견인장치를 이용하여 당길 수 있다.At this time, the pulling rope 70 may be pulled by a manpower, but may be pulled using a mechanical traction device such as a winch or a lever block.

이후 덮개(30)가 수직으로 세워진 상태에서 견인로프(70)를 더 잡아당기게 되면, 덮개(30) 자체의 무게로 인해 뒤로 넘어가면서 보강판(50)에 접촉될 때 첨부도면 도3 및 도8에 도시된 바와 같이 정지되어 열려진 상태를 유지하게 된다.Then, when the tow rope 70 is further pulled in the state in which the cover 30 is standing vertically, when the cover 30 comes in contact with the reinforcing plate 50 while falling back due to the weight of the cover 30 itself, FIGS. 3 and 8 are attached. As shown in the figure, it stops and maintains an open state.

이때 힌지핀(32)이 끼워져 있는 힌지(60)는 덮개(30)가 좌우방향으로 움직이는 것을 방지하는 작용을 하게 되며, 덮개(30)의 후단부에 형성된 회전부(34)는 터널공동구(20)의 좌측 상단에 형성된 반원홈(26)에 지지되어 무거운 덮개(30)를 지지하는 역할을 하게 된다.At this time, the hinge 60 to which the hinge pin 32 is inserted serves to prevent the cover 30 from moving in the left and right directions, and the rotating part 34 formed at the rear end of the cover 30 is a tunnel cavity 20. The semicircular grooves 26 formed on the upper left side of the upper portion serve to support the heavy cover 30.

또, 덮개(30)에 설치되어 있는 굽힘손잡이(40)는 덮개(30)의 우측단을 향해 구부러져 있기 때문에 덮개(30)가 개방된 상태에서도 작업자가 후크(95)의 분리/결합을 편리하게 할 수 있게 된다.In addition, since the bending handle 40 installed on the cover 30 is bent toward the right end of the cover 30, the operator can conveniently detach / join the hook 95 even when the cover 30 is open. You can do it.

그리고, 터널벽면(24)에 설치되어 있는 롤러(80)는 견인로프(70)를 당길 때 견인로프(70)를 부드럽게 안내하는 작용을 하게 된다.Then, the roller 80 provided on the tunnel wall surface 24 serves to smoothly guide the traction rope 70 when pulling the traction rope 70.

그 다음 후크(95)를 굽힘손잡이(40)이로부터 분리한 다음 다른 덮개(30)를 개방하는데 사용하게 되며, 열려진 상태의 터널공동구(20) 점검을 마치고 닫으려 하는 경우에는 후크(95)를 굽힘손잡이(40)에 걸고, 견인로프(70)를 롤러(80)에 건 다음 견인로프(70)를 단단히 잡은 상태에서 굽힘손잡이(40)를 잡고 닫히는 방향으로 덮개(30)를 회전시키게 되면, 덮개(30)가 자중에 의해 닫히게 되며, 덮개(30)가 닫힐 때 견인로프(70)에 인장력을 주게 되면 덮개(30)가 천천히 닫히면서 충격으로부터 보호할 수 있게 된다.Then, the hook 95 is removed from the bending handle 40 and then used to open the other cover 30, and the hook 95 is to be closed when closing and closing the tunnel hole 20 of the open state. When the hook 30 is hooked to the bent handle 40, the tow rope 70 is fastened to the roller 80, and the cover 30 is rotated in the closed direction by holding the bent handle 40 while holding the towing rope 70 firmly. The cover 30 is closed by its own weight, and when the cover 30 is closed, when the tension is applied to the towing rope 70, the cover 30 is slowly closed to protect it from impact.

이때 터널공동구(20)의 우측 상단에 형성되어 있는 자리파기홈(22)으로 굽힘손잡이(40)가 집입되어 자리잡게 되며, 덮개(30)를 닫을 때 사용한 견인로프(70)와 후크(95)는 굽힘손잡이(40)와 롤러(80)로부터 분리하게 되면, 별도로 보관하거나 이동할 수 있게 된다.At this time, the bending handle 40 is inserted into the dent groove 22 formed at the upper right side of the tunnel cavity 20 and seated therein, and the towing rope 70 and the hook 95 used to close the cover 30 are placed therein. When separated from the bending handle 40 and the roller 80, it can be stored or moved separately.

또, 덮개(30)를 터널공동구(20)에서 완전하게 분리하는 경우에는 덮개(30)의 상면에 설치되어 있는 고정손잡이(90)(92)를 두 면의 작업자가 잡고 들어서 이동하거나 견인장치와 벨트 또는 와이어를 고정손잡이(90)(92)에 감은 다음 들어서 이동할 수 있다.In addition, in the case where the cover 30 is completely removed from the tunnel cavity 20, the workers of two sides hold and move the fixed handles 90 and 92 installed on the upper surface of the cover 30, or move it with the towing apparatus. The belt or wire may be wound around the fixed handles 90 and 92 and then lifted and moved.

이때 덮개(30)를 수직방향으로 들어서 올리게 되면, 덮개(30)에 설치되어 있는 힌지핀(32)이 힌지(60)에 형성되어 있는 걸림홈(62)(64)으로부터 분리된다. 즉 걸림홈(62)(64)의 상부가 "U"자 모양으로 개방되어 있기 때문에 덮개(30)를 수직으로 견인하게 되면, 힌지핀(32)이 걸림홈(62)(64)으로부터 빠져나오게 된다.At this time, when the cover 30 is lifted up in the vertical direction, the hinge pins 32 installed on the cover 30 are separated from the locking grooves 62 and 64 formed on the hinge 60. That is, since the upper portion of the locking grooves 62 and 64 is opened in the shape of “U”, when the cover 30 is towed vertically, the hinge pins 32 are pulled out of the locking grooves 62 and 64. do.
