THE MANHOLE COVER EQUIPPED WITH ROAD'S PAVING MATERIALS
The present invention relates to a manhole cover filled with a paving material. A short protrusion (21) is formed on an inner lower end of a manhole frame (20) on which the manhole cover (10) is mounted, and a filling unit (11) wherein the paving material (40) is filled is formed on an upper part of the manhole cover (10) to be concave. A hanging protrusion (13) is formed on an inner upper end of a frame unit (12) of the manhole cover (10) to prevent the cured paving material (40) from being separated. An insertion groove (14) is formed on a bottom of the manhole cover (10) in a circumferential direction, and a pressure ring (30) is inserted into the insertion groove (14). The pressure ring (30) comprises: an inserted unit (31) inserted into the insertion groove (14); and a pressing protrusion (32) protruding to an outer side on a lower part of the inserted unit (31). The pressing protrusion (32) elastically presses an inner surface of the manhole frame (20). As the pressure ring (30) applies a pressure to the inner surface of the manhole frame (20), a sealing property inside the manhole is able to be improved, and the manhole cover filled with the paving material is prevented from being separated from the manhole frame (20) due to an adhesion force of a wheel in accordance with high-speed driving of a vehicle.
본 발명은 포장재 충진형 맨홀뚜껑에 관한 것이다. 그 구체적인 구성은, 맨홀뚜껑(10)이 안착되는 맨홀틀(20)의 내부 하단에는 단턱(21)이 형성되고, 상기 맨홀뚜껑(10)의 상부에는 포장재(40)가 채워지도록 충진부(11)가 오목하게 형성되며, 맨홀뚜껑(10)의 테두리부(12)의 내측 상단에는 상기 양생된 포장재(40)가 이탈되지 않도록 걸림턱(13)이 형성된 구성이다. 또는, 상기 맨홀뚜껑(10)의 저면에는 원주방향을 따라 끼움홈(14)이 형성되고, 상기 끼움홈(14)에는 가압링(30)이 끼워지되, 상기 가압링(30)은 상기 끼움홈(14)에 끼워지는 끼움부(31)와 상기 끼움부(31)의 하부에서 외측방으로 돌출된 가압돌기(32)로 구성되어, 상기 가압돌기(32)가 맨홀틀(20)의 내측면을 탄성적으로 가압하는 구성이다.
