높이조절이 가능한 칼라 주철맨홀{Collar Cast-iron manhole that height control is available}Collar cast-iron manhole that height control is available}

본 발명은 높이조절이 가능한 칼라 주철맨홀에 관한 것으로, 보다 상세하게는 맨홀뚜껑부 옆면에 홈을 형성하여 팽창고무링을 삽입·고정하여 맨홀 내로 빗물이나 침출수 같은 수분이 유입되는 것을 방지하고, 몸체부와 뚜껑부 사이에 높이조절링을 탈·부착할 수 있도록 구성하여 설치 시 높낮이를 조절할 수 있도록 하는 높이조절이 가능한 칼라 주철맨홀에 관한 것이다.The present invention relates to a height-adjustable collar cast iron manhole, and more specifically, to form a groove on the side surface of the manhole cover to insert and fix the expansion rubber ring to prevent the inflow of moisture such as rainwater or leachate into the manhole, the body The present invention relates to a color cast iron manhole that can be height-adjustable so that the height can be adjusted during installation by attaching and detaching the height adjustment ring between the lid and the lid.

일반적으로 맨홀이란 노면에 지하로 사람이 출입할 수 있게 만든 구멍을 말하며, 설치하는 장소는 관의 굵기·방향이 바뀌는 곳, 기점이나 교차점, 길이가 긴 직선부의 중간에 설치되며, 통풍이나 관거의 연락에도 이용된다. 모양은 시공하기가 수월한 원형이 가장 많고, 이 밖에 사각형 및 타원형 등도 있다. 입구는 주위를 철로 만든 틀이나 돌로 테두리를 두르고, 보통 주철 또는 철근콘크리트제인 원형 뚜껑을 덮는다. 본체는 콘크리트 또는 벽돌로 만들며, 통로 구멍의 안지름은 1∼1.2m인 것이 많다. 바닥은 관로의 바닥과 같게 하거나, 다소 내려서 침전물을 수용할 수 있게 만든다. 도로의 지하에는 전화선이나 도시가스관 등이 지중 매설되어 있으며, 이와 같이 매립된 전화선이나 가스관의 고장, 또는 손상이 발생할 경우에, 작업자는 고장점검, 또는 부품교체 등을 하기 위해 맨홀을 이용하여 매립 관으로 출입하게 된다. 이러한 맨홀은 매립 관에 수직으로 연통되도록 도로면에 잠금 설치 되고, 상기 매립 관과 연통되도록 한 맨홀 본체와, 상기맨홀 본체의 상면을덮도록 한 뚜껑으로 구성되며, 주로 도로의 포장 공사 시에 시공·설치되어 왔다. 상기한 맨홀은 도로 포장 공사 시에, 하부를 매립 관에 연통되도록 적정한 높이로 잠금 되게 설치한 후에, 맨홀 뚜껑의 상면과 노면이 일치되도록 아스콘, 또는, 콘크리트 매립작업을 하는 것이다.In general, the manhole refers to a hole made for people to enter and exit the road. The place to install is located in the place where the thickness and direction of the pipe change, the starting point, the intersection point, and the long straight part. It is also used for communication. The shape is the most easy to install round, and there are also square and oval. The entrance is framed with a steel frame or stone around it and covered with a round lid, usually cast iron or reinforced concrete. The body is made of concrete or brick, and the inner diameter of the passage hole is often 1 to 1.2m. The bottom is equivalent to the bottom of the pipeline, or slightly lowered to accommodate the sediment. In the basement of the road, telephone lines and city gas pipes are buried underground.In the event of breakdown or damage of the landfilled phone lines or gas pipes, the worker uses a manhole to check the failure or replace parts. You will enter and exit. The manhole is installed on the road surface so as to communicate vertically with the buried pipe, the manhole main body communicated with the buried pipe, and a lid covering the upper surface of the manhole main body, and is mainly constructed during pavement construction of the road. It has been installed. When the manhole is installed at the road paving work, the lower part is locked to an appropriate height so as to communicate with the buried pipe, and then the asphalt concrete or ascon, so that the upper surface and the road surface of the manhole cover coincide.

그러나 종래의 맨홀은 도로면과 다수 개의 맨홀을 수평 상으로 일치시키기가 어렵기 때문에, 도로면에 시공된 맨홀이 돌출, 또는 함몰되어 도로위로 주행하는 자동차나 사람의 안전에 지장을 초래하였고, 또한 도로면의 손상, 또는 함몰 등으로 인한 도로의 재포장 공사 시에도, 재 포장된 노면이 기존의 노면높이보다 상승하게 되어 차량이 도로를 주행하는 경우 평탄성이 저하되었고, 그로인해 맨홀을 설치한 도로에 하자가 발생되어 차량의 사고가 빈번하게 발생되었으며, 통신선로와 같이 수분에 민감한 곳에 시공한 경우 내부로 빗물이나 침출수 등이 유입되어 선로에 고장을 일으키는 등 많은 문제점이 있었다.However, the conventional manhole is difficult to match the road surface and the plurality of manholes horizontally, and thus, the manholes installed on the road surface are protruded or recessed, which causes the safety of a car or a person traveling on the road. Even when the road is repaved due to damage or sinking of the road surface, the resurfaced road surface is higher than the existing road height, and the flatness is degraded when the vehicle travels on the road. There was a lot of problems, such as a fault occurred in the vehicle frequently occurred, if the construction is sensitive to moisture, such as communication lines, such as rainwater or leachate flows into the interior causing a failure in the track.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창출되는 것으로,The present invention is created to solve the above conventional problems,

그 목적은 맨홀뚜껑부 옆면에 홈을 형성하여 팽창고무링을 삽입·고정하여 맨홀 내로 빗물이나 침출수 같은 수분이 유입되는 것을 방지하고, 몸체부와 뚜껑부 사이에 높이조절링을 탈·부착할 수 있도록 구성하여 설치 시 높낮이를 조절할 수 있도록 하는 높이조절이 가능한 칼라 주철맨홀을 제공하는 것이다.The purpose is to form a groove on the side of the manhole cover to insert and fix the expansion rubber ring to prevent the inflow of water such as rainwater or leachate into the manhole, and to remove and attach the height adjustment ring between the body and the cover. It is configured to provide a height-adjustable color cast iron manhole to adjust the height during installation.

도 5 는 본 발명의 맨홀 뚜껑부 사시도를 도시한 것으로, 상부 면에 다수개의 미끄럼방지 턱(34)과 두개의 회전 홈(33)을 형성하고, 표면을 다양한 색상의PE, PP, EVA 혼합재로 융착하며, 측면에 홈을 형성하여 팽창고무링(32)을 삽입·고정 하며, 상기 팽창고무링(32)의 하부측면 양측에 서로 대칭되게 사각기둥형상으로 두개의 잠금 돌기(31)를 구비하여 형성한다.Figure 5 shows a perspective view of the manhole cover of the present invention, forming a plurality of non-slip jaws 34 and two rotary grooves 33 on the upper surface, the surface of the mixture of various colors of PE, PP, EVA It is fused to form a groove in the side to insert and secure the expansion rubber ring 32, and the two locking projections 31 in the form of a square pillar symmetrically to each other on both sides of the lower side of the expansion rubber ring (32) Form.

상기 팽창고무링(32)은 수분과 접촉하면 수분을 흡수하여 팽창하는 성질을 가지고 있어 수분의 내부 침투를 확실하게 방지할 수 있다.The inflated rubber ring 32 has a property of absorbing moisture and expanding when contacted with moisture, thereby reliably preventing the infiltration of moisture.

상기 PE, PP, EVA 혼합재는 강성이 뛰어난 PE 및 PP와, 탄력성이 뛰어나고, 가교특성 및 발포성, 투명성, 보온성, 내후성이 우수하여 발포성형용으로 사용되며 우수한 코팅재료인 EVA를 혼합하여 매우 단단하면서 동시에 발포성이 있어 고무처럼 탄력성을 구비하며 주철에 대한 접착력이 우수하고 크랙이 발생하지 않는다. 상기와 같은 혼합재는 EVA의 혼합비율에 따라서 탄력성을 조절할 수 있으나, 과도한 양이 혼합 되었을 경우 강성이 떨어지는 단점이 있으므로 50% 이하의 비율로 혼합한다. 따라서 혼합비를 PE 20~30 wt%, PP 20~30 wt%, EVA 5~50 wt%의 비율로 혼합하고, 상기 혼합재에 색소를 혼합하여 다양한 색상의 혼합재를 생성한다.The PE, PP, and EVA mixtures are used for foam molding with excellent stiffness of PE and PP, excellent elasticity, crosslinking properties, foaming properties, transparency, warmth and weather resistance, and are mixed with EVA, an excellent coating material. It is foamy and has elasticity like rubber. It has excellent adhesion to cast iron and does not cause cracks. The mixture as described above can adjust the elasticity according to the mixing ratio of the EVA, but when the excessive amount is mixed, there is a disadvantage that the rigidity is lower, so mix in a ratio of 50% or less. Therefore, the mixing ratio is mixed in a ratio of 20 to 30 wt% PE, 20 to 30 wt% PP, and 5 to 50 wt% EVA, and mixed with the pigment to produce a mixture of various colors.

이하, 본 발명의 실시 예를 첨부도면과 연계하여 상세히 설명하면 다음과 같다.Hereinafter, the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

일반적인 맨홀의 시공 시에는 맨홀의 몸체부(10)에 형성된 잠금 홈(11)에 뚜껑부(30)의 잠금 돌기(31)를 삽치시킨 후 회전 홈(33)에 고리(도시없음)를 삽입하여 회전시켜 뚜껑부(30)를 몸체부(10)에 고정한다.In the construction of a general manhole, the locking projection 31 of the lid part 30 is inserted into the locking groove 11 formed in the body portion 10 of the manhole, and then a ring (not shown) is inserted into the rotating groove 33. Rotating to fix the lid portion 30 to the body portion (10).
