Description

Manhole cover with rigid support and odor-blocking

The present invention relates to a manhole cover capable of providing strong support and blocking odors, and more specifically, by blocking the inflow of fallen leaves or cigarette butts from the outside to prevent clogging and backflow of the manhole, etc., through a blocking means As it is supported from strong external pressure, it reduces damage and reduces noise when moving to a vehicle with a high load. It relates to a possible manhole cover.

In general, a manhole collects rainwater or various types of sewage from the outside and in daily life, and discharges it to a sewage treatment plant or the like. In the case of such a manhole, it is possible to inflow rainwater or various types of sewage while buried in the ground, while preventing foreign substances such as fallen leaves and cigarette butts from entering. In the case of a manhole installed on the back, it should be formed to protect it from strong external pressure because pedestrians or automobiles move to the ground and generate pressure.

For example, according to Korean Utility Model Registration No. 0333416, 'in a hexahedral shape with a hollow inside, a grid-type metal reinforcing member is provided inside, and a wall on each side is molded with fiber-reinforced plastic on the outside thereof; The upper side of the cube is provided with an access hole that allows an administrator to enter and exit and open and close with a manhole cover; an insertion hole into which a water supply pipe is inserted is formed on both sides of the cube; A manhole using fiber-reinforced plastic, characterized in that a plurality of supports for supporting the water supply pipe are integrally formed with the fiber-reinforced plastic on the bottom surface of the interior of the hexahedron.'

However, the manhole using such fiber-reinforced plastics has a problem in that it is difficult to block foreign substances such as fallen leaves or cigarette butts flowing into the manhole, and cannot block the generated odor.

As another example, according to Korean Patent Laid-Open No. 2011-0127824, 'In the manhole for water and sewage, the pedestal (2) of the manhole (1) has a circular edge part (19) protruding in the center part, and the circular edge part (19) on the inner side of the circular lid support portion (4) to form a round groove (5), the round groove (5) is equipped with a rubber ring (6), the outer side of the circular edge portion (19) A plurality of bolt holes 7 and 7' are formed on the flat side of the lower end of the inclined reinforcement bars 8 and 8' formed in a plurality to face in all directions, and the manhole cover 3 is made of synthetic resin (P, E) but with holes 13, 13', and 13" drilled in appropriate places, welded to be arranged in a six-way arrangement with dike-type steel reinforcing rails 12, 12', and 12", and reinforcing steel in the center The load reinforcement beam 30, formed as one by welding the fixing plate 11, is formed to be interpolated when the manhole cover 3 is injection molded, and the locking groove 10 on the upper surface side of the manhole cover 3 ( 10') is formed with handles 9 and 9', and on the bottom side of the manhole cover 3, a round protrusion 16 is protruded in the central portion, and the round protrusion 16 is arranged in the six direction around the digut. On the lower side of the mold rail surfaces 17 and 17 ', synthetic resin inclined reinforcement parts 15 and 15' are formed to be inclined with different heights, and between the inclined reinforcement parts 15 and 15', a support rib 21 is formed. (21") is formed so that the manhole cover 3 and the load reinforcement beam 30 do not bend and rust even under heavy loads.

However, these manholes for water and sewerage can bring superior strength by forming a synthetic resin interpolated load reinforcement beams composed of a dike-type steel reinforcing rail with excellent strength and a reinforcing fixing plate, but the price rises as they are formed with a very heavy load. This causes a problem in that it is impossible to remove the odor.
