본 발명은 맨홀뚜껑과 맨홀프레임의 결합구조에 관한 것이다.The present invention relates to a coupling structure of the manhole cover and the manhole frame.

보다 상세하게는 하수나 오수, 우수 등이 고 수압에 의해 역류할 경우 맨홀뚜껑이 맨홀프레임의 내부 일 측의 힌지돌부를 중심으로 개방되었다가 역류가 해제되면 제자리로 닫치도록 함으로서 맨홀뚜껑의 파손이나 망실을 예방할 수 있게 하고, 또, 맨홀프레임으로부터 맨홀뚜껑의 분해 조립이 매우 손쉽게 이루어지게 함으 로서, 관리가 매우 간편하게 이루어짐과 동시에 관리비용 또한 크게 절감할 수 있게 하기 위한 것이다.More specifically, when the sewage, sewage, rainwater, etc. flow back due to high water pressure, the manhole cover is opened around the hinged stone on one side of the manhole frame, and when the backflow is released, the manhole cover is damaged. It is possible to prevent the loss, and to make the disassembly and assembly of the manhole cover from the manhole frame very easily, so that the management is very simple and at the same time significantly reduce the management cost.

주지된 바와 같이 장마철 홍수발생 시나 집중호우 시 하수나 오수, 또는 우수량이 급격히 늘거나 또는 강이나 하천의 수량이 급격히 늘어 하수관 또는 우수관으로 역류하게 되는 경우에는 역류량에 따라 다소 차이는 있지만 수압을 이기지 못하고 맨홀뚜껑이 벗겨져 이탈되거나 파손되는 상황이 종종발생하게 되며, 이 경우 신속하게 조치하지 않으면 개방된 맨홀로 차량이나 보행자가 빠져 파손되거나 다치게 되는 등의 안전사고가 발생하게 된다.As is well known, when there is a sudden increase of sewage, sewage, or rainwater during a rainy season or heavy rains, or when the quantity of rivers or rivers rapidly increases and flows back to sewers or storm pipes, there is a slight difference depending on the amount of reflux, If the manhole cover is peeled off, it is often separated or damaged. If this is not done quickly, a safety accident such as a vehicle or a pedestrian falls into an open manhole may cause damage or injury.

따라서 이를 해결하는 방안으로 우수나 하수가 역류하더라도 맨홀뚜껑이 쉽게 개방되거나 벗겨지지 않도록 하기 위해 맨홀뚜껑과 맨홀프레임 간에 각종 괘정장치를 구비하거나 또는 볼트나 너트 등을 비롯하여 각종 체결부재로 체결하기도 하였다.Therefore, in order to solve this problem, in order to prevent the manhole cover from being easily opened or peeled off even if rainwater or sewage flows backward, various locking devices are provided between the manhole cover and the manhole frame or fastened with various fastening members including bolts and nuts.

상기와 같이 쉽게 개방되지 못하도록 괘정장치만을 설치 사용하는 전자의 경우는 역류량이 적고 수압이 낮을 경우에 개방되지 않거나 또는 개방되더라도 멀리 달아나지는 않으나, 역류량이 많고 수압이 높을 경우에는 수압에 의해 맨홀이 노출될 정도로 멀리 튕겨나가거나 밀려나가게 되며 이 과정에서 파손되기도 하면서 안전사고의 위험성이 컸던 것이다.In case of the former using only the ruler device to prevent easy opening as described above, when the flow rate is low and the water pressure is low, the manhole is exposed by the water pressure when the flow rate is high and the water pressure is high. It was thrown away or pushed away as much as possible, and it was damaged in the process.

또, 체결부재를 이용하여 맨홀뚜껑을 체결 고정하도록 된 후자의 경우에는 역류하는 우수나 하수가 고압으로 작용하더라도 맨홀뚜껑이 개방되지 않음에 따라 맨홀뚜껑이 달아나는 등의 폐단이 예방되기는 하지만 역류하는 하수나 오수가 각 가정의 하수구나 배수구로 역류하게 되는 경우가 발생하게 되므로 이러한 방법도 바람직하지 못하다.In the latter case, the manhole cover is prevented from being closed due to the fact that the manhole cover does not open even if the rainwater or the sewage is operated under high pressure. This method is also undesirable because sewage or sewage may flow back to the sewer or drain in each household.

또한, 하수나 우수의 역류에 의해 맨홀 뚜껑이 벗겨져 이탈되면 후에 관리자가 일일이 순회점검하면서 다시 덮어주어야만 하는데, 이때 맨홀뚜껑이 제법 무거운 중량물임에 따라 관리 인력과 시간이 과다하게 드는 불합리한 폐단이 따르게 된다.In addition, if the manhole cover is peeled off due to the backwater of sewage or rainwater, the manager must patrol and cover it again afterwards. At this time, the manhole cover is a heavy weight, which leads to an unreasonable closure of excessive manpower and time. .

따라서 본 발명은 전술한 종래의 제반문제점을 해결하기 위해 발명한 것으로, 특히 우수나 하수가 역류하는 경우에 맨홀뚜껑이 맨홀프레임의 힌지돌부를 중심으로 그 역류량 만큼 개방됨으로서 역류를 안정적으로 허용하였다가, 정상화되었을 때 자체중량에 의해 본래의 위치로 닫치게 되는 맨홀뚜껑과 맨홀프레임의 결합구조를 제공함으로서 관리용이 및 안전성 극대화를 유도하려는데 그 목적이 있는 것이다.Therefore, the present invention has been invented to solve the above-mentioned conventional problems, and in particular, when rainwater or sewage flows backward, the manhole cover is allowed to flow stably by opening as much as the amount of backflow around the hinged part of the manhole frame. The purpose of the present invention is to induce maximal management and safety by providing a coupling structure of the manhole cover and the manhole frame which is closed to its original position by its own weight when normalized.
