Description

Improved structure of manhole cover unit and its construction method {IMPROVED STRUCTURE FOR MANHOLE COVER AND ITS CONSTRUCTION METHOD}

The present invention relates to a manhole cover unit and a construction method thereof, and more particularly, a manhole cover unit and a construction method thereof which can prevent the settlement of the manhole cover by providing a manhole cover support to support the manhole cover and the manhole cover support frame. It is about.

In general, the manhole is made of a cylindrical, rectangular block structure of concrete material, the manhole cover unit (assembly) is installed in the entrance formed on the upper part of the manhole block. The manhole cover unit includes a manhole cover supporting frame formed with a seating jaw in the inner diameter so that the manhole cover and the manhole cover is seated.

In addition, the manhole cover base frame of the manhole cover unit is formed with a coupling hole to correspond to the plurality of foundation bolts (anchor bolts) formed around the manhole block entrance and the coupling hole and the foundation bolt is fixed and installed by a fixing means such as a nut.

However, when constructing these manhole blocks and manhole cover units, manhole cover frames should be installed in advance of the height of the road before paving begins on the road. Otherwise, the manhole cover is more than the road after the road construction is completed. It will be lower or higher construction. Vehicles traveling on the road due to such construction errors may be severely impacted, causing damage or accidents to the vehicle.

Therefore, in order to prevent this, the manhole cover base frame coupled to the foundation bolt is spaced apart from the manhole block to tighten or loosen the nut fastened to the foundation bolt to compensate for the height, but the height of the manhole cover frame When the nut is raised to the upper side to release the nut, a gap is generated between the lower part of the manhole cover and the manhole block, so that concrete or asphalt flows into the manhole through the gap when concrete is placed or paved on the road. .

In addition, in order to match the height of the manhole cover and the road, when the manhole block is constructed, there is a case in which the height is adjusted by stacking bricks between the manhole block and the manhole cover base frame, in which case rainwater or sewage is a gap between the bricks. There is a problem that the settlement phenomenon occurs by seeping into the tightness between the bricks.

In addition, the conventional manhole cover unit after the road paving, because the concrete or asphalt flowing into the interior of the manhole cover base, the inner circumference of the manhole becomes messy and degrades the quality of the manhole, so using a finishing material such as mortar The work that needs to be done is required.

As such, the conventional manhole cover unit has a subsidence phenomenon and aesthetic defects are generated, and the maintenance cost and time and economic loss due to the control of the road to compensate for this additionally occurs.
