Description

Opening and Closing device of manhole}

The present invention relates to an insertion hole opening and closing device of the manhole, and more particularly to an insertion hole opening and closing device of the manhole for preventing the introduction of foreign matter through the insertion hole formed in the manhole.

In general, manholes are always installed at the lower part of the road because various communication cables are installed, including water, sewerage, power lines, and the like.

The manhole is made of a cylindrical, rectangular block structure of concrete, the manhole cover assembly is installed for the entrance formed on the upper part of the manhole block (upper block).

In addition, the manhole cover assembly consists of a lid and a lid support frame to form a seating jaw in the inner diameter so that the lid is supported.

The manhole cover assembly is provided with a plurality of foundation bolts (anchor bolts) installed on the upper circumference of the entrance and exit of the manhole block, and the nut is fixed to the foundation bolts by inserting a coupling hole formed around the lid support frame corresponding to the foundation bolts. .

In the conventional manhole opening and closing device, as shown in FIG. 1, a handle-shaped fixing groove 4 is formed in a manhole cover of a manhole frame 3 fixedly installed in the manhole device, and the foreign matter through the fixing groove 4. The rubber stopper 6 is further provided so that it is not inserted.

As described above, the conventional manhole opening and closing device inserts a rubber stopper 6 into the fixing groove 4 of the manhole frame 3 to seal the fixing groove 4 through the fixing groove 4 of the manhole frame 3. It is to prevent foreign substances from entering.

However, the conventional manhole opening and closing device was closed using a rubber stopper to prevent foreign substances from entering through the fixing groove of the manhole frame, but after inserting the rubber stopper into the fixing groove, the rubber from the fixing groove during the manhole work Difficult to separate the stopper there was a problem that the workability is reduced.

The present invention relates to a manhole insertion opening and closing device for solving the above problems, and in particular, to prevent the inflow of foreign matter through the insertion hole formed in the manhole and to improve the convenience of work during manhole operation.

The present invention is inserted into the sealing member detachably inserted into the insertion hole formed in the manhole; An insertion hole is formed in the sealing member, and a hook part is inserted into the insertion hole or a sealing member is detachably inserted into an insertion hole formed in the manhole; A locking groove is formed at both ends of the upper surface of the sealing member to achieve opening and closing of the manhole insertion opening.

The present invention as described above can open and close the insertion hole of the manhole to improve the convenience of work while at the same time blocking the inflow of foreign substances in advance to reduce the time to remove the foreign matter of the insertion hole when opening and closing the manhole, as well as shortening the maintenance time of the reptiles such as snakes By blocking the invention is effective to improve the safety of the worker.
