본 발명은 맨홀의 추락방지구조에 관한 것이다.The present invention relates to a fall prevention structure of the manhole.

보다 상세하게는 맨홀 내부의 청소나 각종작업과정에서 맨홀뚜껑을 개방시켜 놓거나, 또는 오수나 우수의 강한 역류수압에 의해 맨홀뚜껑이 벗겨지고 보행자 또는 차량이 부주의 등으로 인해 이를 식별하지 못한 상태에서 보행 또는 주행하더라도 맨홀 내부로 추락하게 되는 등의 안전사고를 사전에 예방할 수 있게 함으로서 안전성과 신뢰성을 극대화시킬 수 있게 하기 위한 것이다.More specifically, the manhole cover is opened during cleaning or various work processes inside the manhole, or the manhole cover is peeled off due to filthy water or strong strong backwater pressure, and the pedestrian or vehicle cannot walk due to inadvertent identification. Or even to drive in order to prevent safety accidents such as falling into the manhole in advance to maximize the safety and reliability.

주지된 바와 같이 맨홀뚜껑을 열면 사각 또는 원형 형태의 깊은 웅덩이 형태의 구멍이 존재하게 되고, 내부에는 맨홀의 용도에 따라 각종 하수 또는 오수의 집수와 각종 통신용 매립전선, 가스나 유류배관 등, 다양한 형태의 시설물이 설치되어 있다.As is well known, when opening the manhole cover, there is a hole in the form of a deep puddle in the form of a square or a circle, and there are various forms such as collection of various sewage or sewage and landfill wires for communication, gas or oil piping according to the purpose of the manhole. Facilities are installed.

상기 하수나 오수의 경우에는 주기적으로 슬러지 등을 제거하는 등의 맨홀 청소를 해 주어야 하고, 용도에 따른 각종 맨홀의 경우도 주기적으로 점검과 더불어 청소나 수리 등을 하게 되며, 따라서 수시로 맨홀뚜껑을 개방시키게 된다. 또한, 폭우나 홍수 등이 발생하는 경우에는 하수나 오수가 역류하여 넘치는 경우도 종종 발생하고 있으며 이 때 역류수압이 강해지면 맨홀뚜껑이 벗겨지게 되며, 이를 인식하지 못한 상태에서 보행 또는 주행하는 경우에는 맨홀 내부로 추락하게 되어 인명사고까지 발생되기도 하는 등 많은 폐단이 따르게 되었던 것이다. In the case of sewage or sewage, the manhole should be cleaned by periodically removing sludge and the like, and various manholes according to the use are periodically checked, cleaned or repaired, and thus the manhole cover is frequently opened. Let's go. In addition, when heavy rains or floods occur, sewage or sewage is often overflowed, and when the backwater pressure increases, the manhole cover is peeled off. Many mansions were followed, including falling into the manhole and even causing personal accidents.

따라서 본 발명은 전술한 종래의 제반문제점을 해결하기 위해 안출된 것으로서, 특히, 맨홀프레임의 내부구멍에 분해조립이 용이한 절첩식안전망을 설치함으로서 홍수나 폭우에 의해 맨홀뚜껑이 벗겨져 달아나더라도 보행자가 맨홀로 추락하는 등의 안전사고를 사전에 예방할 수 있게 하려는데 그 목적이 있는 것이다.Therefore, the present invention has been made to solve the above-mentioned conventional problems, in particular, by installing a folding safety net easy to disassemble and assemble in the inner hole of the manhole frame even if the manhole cover is peeled off by flood or heavy rain, pedestrians The aim is to help prevent accidents such as falling into a manhole in advance.

오수나 하수맨홀, 통신선로용 맨홀, 가스나 유류관이 설치된 맨홀 등을 비롯하여 인도 또는 보도나 골목 등에 설치되는 다양한 용도의 맨홀에 있어서,In manholes for various purposes, such as sewage or sewage manholes, manholes for communication lines, manholes with gas or oil pipes, etc.

도1 ~ 도2는 본 발명의 제1 실시예이고 도3 ~ 도4는 제2 실시예로서 이는 원형 또는 사각 맨홀프레임(1)의 내부 구멍(11)에 보행자나 차량의 추락을 방지할 수 있으면서 인위적으로 개폐 가능하며 절첩힌지부(22)를 중심으로 절첩이 가능하게 한 절첩식 안전망(2)을 설치하되, 맨홀프레임(1)에는 뚜껑안착턱(12) 직하부의 대향하는 벽면 양측에 개방부(13a)와 수평유도부(13b) 및 걸림안착부(13c)로 이루어진 "

도5는은 본 발명의 제3실시예를 나타낸 것으로,5 shows a third embodiment of the present invention,

이는 상기한 제1실시예의 구성에서 절첩부(25)에 걸림돌기(21)를 더 형성하고, 맨홀프레임(1)에도 상기 절첩부 걸림돌기(21)가 위치하는 부분에 끼움홈(13')을 형성하여 안전성을 한층 더 높인 것이다.This further forms a locking projection 21 in the folding portion 25 in the configuration of the first embodiment, the fitting groove 13 'in the portion where the folding portion locking projection 21 is located in the manhole frame 1 as well. To form a higher level of safety.

또, 도 6은 본 발명의 제4실시예를 나타낸 것으로,6 shows a fourth embodiment of the present invention.

이는 절첩식 안전망(2)의 양단면에 1~다수개의 걸림돌기(21)를 더 돌출형성하고, 맨홀프레임(1)에는 상기 걸림돌기(21)가 위치하는 곳에 끼움홈(13")을 형성한 것이다. It further protrudes from 1 to a plurality of locking projections 21 on both end faces of the folding safety net 2, and the fitting hole 13 "is formed in the manhole frame 1 where the locking projections 21 are located. It is.

이와 같이 구성된 본 발명은 맨홀(100)의 구멍(11) 내부, 즉 맨홀뚜껑(3)의 하측에 분해조립이 가능한 절첩식 안전망(2)이 설치된 구성임에 따라 맨홀의 용도에 따른 각종 작업과정에서 맨홀뚜껑(3)을 개방시켜 놓은 상태이거나, 또는 폭우나 집중호우로 인하여 하수나 오수, 또는 우수가 역류함에 따라 맨홀뚜껑(3)이 벗겨진 경우에 이를 인식하지 못한 상태에서 보행 또는 주행하더라도 안전망에 의해 추락이 예방되게 되는 특징이 따르게 된다.According to the present invention configured as described above, since the folding safety net 2 capable of being disassembled and installed is installed inside the hole 11 of the manhole 100, that is, the manhole cover 3, various work processes according to the use of the manhole. Even if the manhole cover (3) is open in the state or the manhole cover (3) is peeled off due to backwater, sewage, or rainwater due to heavy rain or heavy rain, the safety net is not recognized. Followed by the feature that the fall is prevented by.

다시말하면, 본 발명은 절첩식 안전망(2)이 조립과 분해가 손쉽게 이루어지는 구성이면서도 우수나 하수의 역류시에 벗겨지거나 분해되지 않게 되는데, 이는 맨홀프레임(1)의 뚜껑안착턱(12) 직하부에 형성된 내측벽면에 절첩식 안전망(2)의 걸림돌기(21)와 대응하는 끼움홈(13)이 형성되어 있고, 상기 끼움홈(13)은 개방부(13a)와 수평유도부(13b) 및 걸림안착부(13c)로 이루어진 "
