도 5는 본 발명의 다른실시예를 나타낸 맨홀뚜껑의 요부측면예시도.Figure 5 is an exemplary side view showing the main portion of the manhole cover showing another embodiment of the present invention.

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 맨홀프레임에 맨홀뚜껑을 조립함에 있어서, 분해 조립이 매우 손쉽게 이루어지고, 우수나 하수의 역류시에는 수압에 의해 맨홀뚜껑이 개방되었다가 수압이 해제되면 자동으로 본래의 위치로 닫칠 수 있게 함으로서 수압에 의한 맨홀뚜껑의 파손예방과 더불어 관리 또한 매우 수월하게 이루어지게 하기 위한 것이다.More specifically, in assembling the manhole cover in the manhole frame, disassembly and assembly is very easy, and when the rainwater or sewage flows backward, the manhole cover is opened by water pressure and then automatically closed when the water pressure is released. In order to prevent damage of the manhole cover by hydraulic pressure, the management is also very easy.

주지된 바와 같이 장마철이나 집중폭우시 하수나 우수량이 급격히 늘거나 또는 강이나 하천의 수량이 급격히 늘어 하수관 또는 우수관으로 역류하는 경우에는 수압을 이기지 못하고 맨홀뚜껑이 벗겨져 달아나거나 파손되는 상황이 종종발생하게 되며, 이 경우 맨홀이 개방된 상태로 방치되기 쉬워 차량의 주행 또는 보행시 빠지게 되는 안전사고가 발생하게 된다.As is well known, when rainy season or heavy rains rapidly increase the amount of sewage or rainwater, or when the quantity of rivers or rivers rapidly increases and flows back into the sewer or rainwater pipes, the manhole cover may be peeled off or damaged due to water pressure. In this case, the manhole is easy to be left in an open state and a safety accident occurs when the vehicle runs or walks.

따라서 이를 해결하는 방안으로 우수나 하수가 역류하더라도 맨홀뚜껑이 쉽게 개방되거나 벗겨지지 않도록 하기 위해 맨홀뚜껑과 맨홀프레임간에 각종 괘정장치를 구비하거나 또는 볼트나 너트 등을 비롯하여 각종 체결부재로 체결하기도 하였는데, 쉽게 개방되지 않도록 괘정장치만 설치 사용하는 전자의 경우는 역류량이 적고 수압이 낮을 경우에는 개방되지 않거나 또는 개방되더라도 멀리 달아나지는 않으나, 역류량이 많고 수압이 높을 경우에는 수압에 의해 멀리 튕겨나가게 되어 파손되기도 하면서 안전사고의 위험성이 컸고, 체결부재를 이용하여 맨홀뚜껑을 체결 고정하는 후자의 경우에는 역류하는 우수나 하수가 고압으로 작용하더라도 맨홀뚜껑이 개방되지 않음에 따라 맨홀뚜껑이 달아나는 등의 폐단은 예방되기는 하지만 역류하는 하수나 오수가 각 가정의 하수구나 배수구로 역류하게 되는 경우가 발생하게 되므로 이러한 방법도 바람직하지 못하다.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. In the case of the former, which uses only a ruler to prevent easy opening, the amount of backflow is small and when the water pressure is low, it does not open or does not run away even if it is open.However, when the flow rate is high and the water pressure is high, it may be thrown away by water pressure and damaged. However, the risk of safety accidents was high, and the latter case of fastening the manhole cover by using the fastening member in the latter case, even if the rainwater flowing back or the sewage acts under high pressure, the manhole cover may run away due to the manhole cover not opening. Prevented but refluxing Or waste water is not preferable also because such a way as occurs when the flow back to the drain or drains in each home.

또한, 하수나 우수의 역류에 의해 맨홀 뚜껑이 벗겨져 이탈되게 되면 후에 관리자가 일일히 다시 덮어주어야만 함에 따라 관리 인력과 시간이 과다하게 드는 불합리한 폐단도 따랐다.In addition, if the manhole cover was peeled off due to backflow of sewage or rainwater, the manager had to cover it again one by one, which led to the unreasonable dismantling of excessive manpower and time.

본 발명은 전술한 종래의 제반문제점을 해결하기 위해 발명한 것으로, 특히 우수나 하수가 역류하는 경우에 그 역류량만큼 맨홀뚜껑이 개방되고, 정상화되게 되면 자동으로 본래의 위치로 닫치게끔 한 맨홀뚜껑과 맨홀프레임의 결합구조를 제공함으로서 관리 용이 및 안전성 극대화를 유도하려는데 그 목적이 있는 것이다.The present invention has been invented to solve the above-mentioned conventional problems, especially when the rainwater or sewage backflow, the manhole cover is opened as much as the amount of backflow, and when normalized, the manhole cover is automatically closed to its original position. By providing a combined structure of the manhole frame and the purpose is to induce easy management and maximum safety.
