Description

Manhole device {MANHOLE}

The present invention relates to a manhole device, and more particularly, to a manhole device that can adjust the height and the slope so that the height and the slope can match the road surface.

In general, manholes are provided for human access to inspect or clean underground pipes, telecommunications, etc., usually where the thickness or direction of buried piping is diverted, but the origin, intersection, and length are long. It is installed in the middle of the straight part.

Since the entrance of the manhole is normally opened toward the road surface, a cover is mounted so that there is no inconvenience in passing by a vehicle traveling on a road on which the manhole is formed or a pedestrian walking on a sidewalk.

On the other hand, the manholes as described above are installed on the upper side of the manhole mostly formed on the road surface, so that the cover does not protrude onto the road surface, so as to maintain a horizontal relationship with the road surface.

However, due to the ground subsidence caused by the load of the vehicle, the road is lost or damaged, so that the road surface can be overlaid for the flatness of the road. Occurred.

In addition, when the road is inclined, the top of the manhole must be formed to be inclined to be suitable for the inclination, thereby making the work of cutting and welding the accessories complicated and complicated.

In addition, if a deformation occurs in the height and inclination of the road, the manhole must be re-installed every time, and this reinstallation work is cumbersome, complicated, and expensive, resulting in problems such as lack of budget and limited road use due to prolonged working period. There was a problem that the maintenance work could not be done in time.

The present invention has been made to solve the above problems of the prior art, the upper structure having an opening in the top of the manhole in the form of a corrugated tube that can be expanded and changed angle, the lower body portion is a multi-stage assembly structure is variable in length It is an object of the present invention to provide a manhole device that makes it easy to adjust the height and angle by taking the, and to perform the maintenance work in a timely manner by the ease of such adjustment work.

An object of the present invention described above is a manhole device embedded in the ground, buried in the ground, the body is composed of a plurality of divided bodies; An upper body coupled to an upper end of the body, the upper body comprising an elastic corrugated tube; A support mounted to an upper opening of the upper body; Connecting means for connecting the support and the upper body to set the height and the inclination of the upper body; It can be achieved by a manhole device comprising a cover coupled to the support to seal the interior.

The body has a through-hole formed so that the pipe is connected to both sides, the upper portion is opened, the lower body having a receiving space therein; A hollow intermediate coupled to an upper end of the lower body; It is coupled to the upper end of the intermediate body, the receiving space is formed therein, and the upper body formed with a circular step having an opening hole at the upper end is characterized in that the vertically laminated coupling.

The connecting means is composed of a bolt having a predetermined length, and a nut coupled to the end of the bolt, the lower part of the bolt is screwed to the annulus of the upper body, the upper part of the bolt is coupled to the support through the nut It is characterized in that the fastening is installed to be fixed.

The coupling surface of the lower body, the intermediate body and the upper body is characterized in that the index ring is installed to have an airtight performance.

The index ring is characterized in that it is inserted into the groove formed in the coupling surface.

According to the present invention, since the upper body of the upper end of the manhole can be extended or the inclination can be set appropriately so as to be suitable for the height difference and the inclination of the road, the installation of the most ideal manhole can be easily performed.

In addition, by installing an index ring on the manhole body and the upper body can maintain the airtightness can block the inflow of rainwater or groundwater from the outside.
