Abstract

A dual-configure manhole cover is provided to drain water easily while effectively blocking bad smell derived from a passage of water pipes by using the dual-configure manhole cover. A dual-configure manhole cover comprises a manhole supporting frame(20) formed with an inlet communicated with a manhole and a dual cover member. The manhole supporting frame has a first protrusion at an inner surface thereof. A second protrusion(22) having inserting grooves(23) is formed on the first protrusion. The dual cover member includes upper and lower manhole covers. The upper manhole cover is mounted to the second protrusion to close the inlet. The lower manhole cover(30) has a locking portion corresponding to the inserting grooves at an outer surface thereof.

The present invention relates to a double-shaped manhole cover, and more particularly, to a double manhole cover for opening and closing a manhole in communication with an underground buried passage, and opening the upper manhole cover for smooth drainage of rainwater due to heavy rain. In this case, the lower manhole cover formed inside the manhole support frame prevents the waste of wastes contained in the rainwater from accumulating inside the sewer and prevents the risk of falling into the open manhole, and a plurality of drainages communicating with the inlet. In addition to forming a hole to serve as a smooth drainage, the lower manhole cover forms a locking piece corresponding to the insertion groove of the second support jaw so that the locking piece is positioned in the gap, so that the locking piece is rotated left and right. It relates to a double-shaped manhole cover that is located on the bottom surface of the second support jaw to prevent separation.

In general, the manhole is formed in a circular or rectangular shape for drainage of water, sewage, telecommunication facilities, etc. and drainage of rainwater, which are buried underground, such as roads or sidewalks. Is installed to communicate, and the underground facilities are closed by locking or fitting the manhole cover to the opening frame of the manhole communicating with the outside.

Usually, sewer bodies for draining rainwater to sewers are embedded in roadsides and residential areas, and sewage caps are formed in the upper part of the sewers in which the reinforcing frames are welded to the grid.

Accordingly, the drain cover drains rainwater from roadsides and residential areas to the sewer in rainy weather.

However, such a conventional sewer lid is made of a lattice by reinforcing frames, and various wastes having a small volume such as cigarette butts or plastic bags are normally stacked on the bottom of the sewer by passing through the lattice.

As a result, there is a problem that the sewer is clogged when it rains due to garbage falling on the sewer floor.

In addition, there is a problem in that the cost for the cleaning work is consumed with the inconvenience of periodically cleaning the inside of the sewer in order to prevent the sewer clogging.

The present invention has been made to solve the above problems, an object of the present invention in the manhole cover for opening and closing the manhole in communication with underground buried passages, such as water, sewage, the first and second support projections protruding on the inner peripheral surface Manhole support frame having a double cover member consisting of a top manhole cover coupled to the upper surface of the first support jaw and a lower manhole cover located in the gap between the first support jaw and the second support jaw, rainwater during heavy rain Even if the upper manhole cover is opened for smooth drainage, the lower manhole cover prevents the risk of fallout, filters waste products flowing with rainwater, and forms a plurality of drainage holes communicating with the inlet to help smooth drainage. The lower manhole cover has a plurality of engaging pieces corresponding to the insertion grooves of the second supporting jaw on the outer circumferential surface thereof so as to be rotated and fixed left and right in the gap. 2 there is provided a manhole cover formed into.

Other objects and advantages of the invention will be described below and will be appreciated by the embodiments of the invention. Furthermore, the objects and advantages of the present invention can be realized by means and combinations indicated in the claims.

The present invention has the following features to achieve the above object.
