APPARATUS FOR PREVENTING FALLING INTO MANHOLE
The present invention discloses a falling prevention apparatus for a manhole. According to the present invention, the falling prevention apparatus for a manhole includes: a mounting length control unit (110) having the upper part opened in a round shape or a square shape and including a first mounting groove (21) on which a manhole cover (10) is mounted along a rim, wherein the mounting length control unit (110) comprises: four or more cover nuts (111) formed to be symmetric to be mounted on an inner wall of a manhole or a second mounting groove (22) of a manhole structure (20) having the second mounting groove (22) stepped at a fixed height by being adjacent to the inner side of the first mounting groove (21); a support plate (112) which the cover nut (111) is coupled with by penetrating the same; and a bolt (113) fixed to a rear end of the cover nut (111) passing through the support plate (112); a first support end (120) connected to both sides of a rear end of the support plate (112) on the opposite side by extending from both sides of the rear end of the support plate (112); a second support end (130) formed to be symmetric between the first support ends (120) and connected by extending from the second mounting groove (22) to the first support end (120); and a first polygonal support end (140) connected in a polygonal ring type by crossing the first support end (120) and the second support end (130). A bolt (113) of the mounting length control unit (110) rotates according to the diameter of an inner wall surface of the manhole or the second mounting groove (22) of the manhole structure (20) to adjust mounting of the cover nut (111) to the inner wall surface of the manhole or the second mounting groove (22). The falling prevention apparatus for a manhole can prevent separation due to backflow of rainwater and the like.
본 발명은, 상부가 원형 또는 사각형으로 개방되고, 맨홀 덮개(10)가 안착되는 제1안착홈(21)이 테두리를 따라 형성되고, 제1안착홈(21)의 내측에 인접하여 일정 높이로 단차진 제2안착홈(22)이 형성된 맨홀 구조물(20)의 제2안착홈(22) 또는 맨홀 내부벽면에 안착되도록 4개 이상 대칭적으로 형성된 덮개너트(111)와, 덮개너트(111)가 관통하여 체결되는 지지판(112)과, 지지판(112)을 통과한 덮개너트(111)의 후단에 고정된 볼트(113)로 이루어진, 안착길이 조절부(110), 지지판(112)의 후단의 양측으로부터 연장되어 맞은편 지지판(112)의 후단의 양측에 결합되는 제1지지단(120), 제1지지단(120) 사이에 대칭적으로 형성되고, 제2안착홈(22)으로부터 제1지지단(120)까지 연장되어 결합되는 제2지지단(130), 및 제1지지단(120)과 제2지지단(130)을 가로질러 다각형 형상의 링 타입으로 결합된 제1다각형지지단(140)을 포함하고, 맨홀 구조물(20)의 제2안착홈(22) 또는 맨홀 내부벽면의 직경에 따라 안착길이 조절부(110)의 볼트(113)를 회전하여 제2안착홈(22) 또는 맨홀 내부벽면으로의 덮개너트(111)의 안착을 조정하는, 맨홀용 추락 방지 장치를 개시한다.
