Abstract
본 고안은 종래 맨홀틀과 맨홀뚜껑으로 구성되어지는 맨홀에 있어서 상기 맨홀틀(30)의 뚜껑걸림턱(31)에 돌출대삽입공(41)이 천공된 돌출편(40)을 형성하고, 맨홀뚜껑(10)의 저부에는 돌출대(20)를 돌설시키되 상기 돌출편(40)의 돌출대삽입공(41)과 동일한 위치에 형성하도록 구성하므로써, 홍수시 하수관으로부터 역류된 빗물에 의해 맨홀뚜껑이 맨홀틀로부터 이탈된다고 하더라도 맨홀뚜껑의 돌출대가 맨홀틀의 돌출대삽입공에 내삽되어 있으므로 맨홀뚜껑의 위치는 변동되지 않으므로 홍수시 맨홀이 물에 잠겨있다 하더라도 보행자가 맨홀구멍에 빠지는 불상사는 방지할 수 있는 것이다.The present invention is formed in the manhole consisting of a manhole frame and a manhole cover in the prior art to form a protruding piece 40 in which the protrusion insertion hole 41 is perforated in the lid catching jaw 31 of the manhole frame 30. At the bottom of the lid 10, the protrusion 20 is projected to be formed at the same position as the protrusion insertion hole 41 of the protrusion piece 40, so that the manhole cover is closed by rainwater flowing back from the sewer pipe during the flood. Even if the manhole is released from the manhole cover, the manhole cover's protrusion is inserted into the manhole's protrusion insertion hole, so the position of the manhole cover is not changed. It is.
Description
본 고안은 안전사고를 방지할 수 있는 맨홀에 관한 것으로, 특히 홍수시 맨홀에 빠져 익사하는 것을 방지하기 위한 맨홀에 관한 것이다.The present invention relates to a manhole that can prevent safety accidents, and more particularly to a manhole to prevent drowning drowning in the flood.
즉 종래의 맨홀의 구조는 지반에 묻혀진 상태의 맨홀틀과 상기 맨홀틀의 걸림턱에 얹혀 결합되는 맨홀뚜껑으로 구성되어 있다. 그런데 상기 맨홀뚜껑은 맨홀틀에서 단순히 얹혀져 결합된 구조이므로 평상시에는 아무런 위험요소가 없지만 많은 비로 인해 홍수가 질 때 하수구에서 빗물이 역류하기도 하는데 이때 맨홀뚜껑의 저부에서 미는 수압에 의해 맨홀뚜껑이 열려 물에 떠밀려 제자리로부터 벗어나게 되는 경우가 있다. 이런경우에는 대개 주위가 모두 물에 잠겨있는 상태이므로 보행자에게는 맨홀구멍이 보이질 않게되고 따라서 맨홀에 빠져 익사하는 경우가 빈번하게 발생하고 있는 실정이다.In other words, the structure of the conventional manhole consists of a manhole cover buried in the ground and a manhole cover coupled to the engaging jaw of the manhole frame. However, since the manhole cover is simply mounted on the manhole frame and is combined, there is no danger in normal operation, but rain may flow back from the sewer when floods occur due to a lot of rain. You may be pushed back out of place. In this case, since the surroundings are usually submerged in water, the manhole hole is not visible to the pedestrian, and thus, the manhole is drowned and drowned frequently.
물론 종래의 맨홀뚜껑에도 약간의 배기공과 배수공이 뚫려있긴 하나 이는 홍수시의 역류되는 빗물에는 큰 의미가 없다.Of course, although some exhaust and drain holes are also drilled in the conventional manhole cover, this does not mean much to the rainwater flowing back during flooding.
따라서 본 고안은 홍수시 맨홀뚜껑이 벗겨져 안전사고가 발생하는 폐단을 해결하기 위하여 종래 맨홀의 구조를 크게 변형하지 않고도 이를 해결할 수 있도록 한 것으로, 종래 맨홀틀의 뚜껑걸림턱에 돌출대삽입공이 천공된 돌출편을 형성하고, 맨홀뚜껑의 저부에는 돌출대를 상기 돌출편의 돌출대삽입공에 대향되는 위치에 형성하여 돌출대가 돌출대삽입공에 내삽되는 구조를 갖는 것이다.Therefore, the present invention is to solve this problem without a significant modification of the structure of the conventional manhole in order to solve the end of the manhole cover is peeled off during the flood, safety accidents, the protrusion insertion hole is perforated in the lid hanging jaw of the conventional manhole frame Protruding pieces are formed, and at the bottom of the manhole cover, a protruding bar is formed at a position opposite to the protruding bar insertion hole of the protruding piece so that the protruding bar is inserted into the protruding bar insertion hole.
따라서 본 고안은 홍수시 하수관으로부터 역류된 빗물이 배출될 수 있도록 하되 맨홀뚜껑은 다시 자기 위치로 놓일 수 있도록 함을 목적으로 하는 것으로, 강제로 역류된 빗물을 못나오게 막는 구조의 맨홀과는 다른 목적을 갖는다.Therefore, the present invention aims to allow rainwater backflowed from the sewer pipe to be discharged during flooding, but the manhole cover can be put back in its own position.

본 고안의 구성을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.Referring to the configuration of the subject innovation in detail as follows.
도 1는 본고안의 구성을 보이기 위한 사시도로써, 본 고안은 종래 맨홀틀(30)의 뚜껑걸림턱(31)에 돌출대삽입공(41)이 천공된 돌출편(40)을 형성하고, 맨홀뚜껑(10)의 저부에는 돌출대(20)를 돌설시키되 상기 돌출편(40)의 돌출대삽입공(41)과 동일한 위치에 형성하도록 한 것이다.1 is a perspective view for showing the configuration of the present invention, the present invention forms a protrusion piece 40 in which a protrusion insertion hole 41 is perforated in the lid catching jaw 31 of the conventional manhole frame 30, and a manhole cover The bottom of the (10) is to project the projection 20, but to be formed in the same position as the projection insertion hole 41 of the projection piece (40).
따라서 맨홀뚜껑(10)은 도 2에 도시한 바와같이 상기 맨홀뚜껑의 저부에 형성된 돌출대(20)가 맨홀틀(30)의 내주면에 형성된 돌출대삽입공(41)에 내삽된 상태로 맨홀틀(30)에 결합되어지며, 도 3 사용상태도에 도시한 바와같이 홍수가 져 맨홀뚜껑이 저부로부터 수압을 받게되면 뚜껑이 열리면서 역류된 빗물을 배출할 수 있도록 한다.Therefore, the manhole cover 10 is a manhole frame as shown in Figure 2, the protrusion 20 formed on the bottom of the manhole cover is inserted into the protrusion insertion hole 41 formed on the inner circumferential surface of the manhole frame 30 It is coupled to 30, and as shown in the use state diagram of Figure 3 when the flooded manhole cover receives the water pressure from the bottom to open the lid to discharge the rainwater backflow.
이때 맨홀뚜껑은 맨홀틀에서 상승되어지되 돌출대(20)가 돌출대삽입공(41)에 아직 내삽된 상태이므로 수압을 가지는 역류된 빗물은 맨홀뚜껑과 맨홀틀의 열린 틈으로 배출된다고 하더라도 맨홀뚜껑이 맨홀구멍으로부터 이탈된 상태는 아니므로 맨홀이 물에 잠겨있다 하더라도 보행자가 맨홀구멍에 빠지는 불상사는 방지할 수 있는 것이다.At this time, the manhole cover is raised from the manhole frame, but since the protrusion 20 is still inserted into the protrusion insertion hole 41, the backwater having a hydraulic pressure is discharged into the manhole cover and the open gap of the manhole frame, even though the manhole cover is discharged. Since it is not separated from the manhole hole, even if the manhole is submerged in water, it is possible to prevent a pedestrian from falling into the manhole hole.
이처럼 본 고안은 수압을 가지는 역류된 빗물에 의해 맨홀뚜껑이 맨홀틀로부터 이탈된다고 하더라도 맨홀뚜껑의 돌출대가 맨홀틀의 돌출대삽입공에 내삽되어 맨홀뚜껑의 위치는 변동되지 않으므로 홍수시 맨홀이 물에 잠겨있다 하더라도 보행자가 맨홀구멍에 빠지는 불상사는 방지할 수 있는 것이다.Thus, even if the manhole cover is separated from the manhole frame by the countercurrent rainwater with hydraulic pressure, the manhole cover is inserted into the protrusion insertion hole of the manhole frame and the position of the manhole cover is not changed. Even if locked, it is possible to prevent pedestrians falling into manholes.
