Description

Device for connecting underground pipes}

The present invention relates to a underground buried pipe connecting device for embedding a communication cable or a power cable underground, and more specifically, the underground buried pipes of a certain length for embedding a communication cable or power cable underground It relates to a underground buried pipe connection device for easy and safe connection.

In general, a pipeline for laying a communication cable or a power cable underground is formed by connecting a plurality of underground burial pipes produced to a certain length, and these underground burial pipes are connected to the underground burial pipes at the same time. Waterproofing is also basically implemented to prevent water from seeping.

Conventionally, the adjacent ends of two underground buried pipes to be connected are connected by a suitable cylindrical connecting pipe, and the connection between the underground buried pipe and the waterproofing work is performed at the same time by filling the end of the connecting pipe and the underground buried pipe with waterproof pitch material.

However, the conventional method of connecting the underground buried pipe is the same as simply inserting the underground buried pipe into the connecting pipe. Therefore, when the underground buried pipe is buried because the connection state of the underground buried pipe is unstable, There was a problem that water penetrates into the pipeline through the site.

In order to solve this problem, underground buried pipe connection devices such as Korean Patent Application Publication No. 10-1998-070464, Utility Model Registration No. 20-348290, and Korean Utility Model Publication No. 20-2009-12209 have been developed.

However, the above-mentioned prior arts have a slightly different name for each case, and a fixing band for tightening the upper end with bolts and nuts, and underground buried pipes are inserted into the fixing band by both sides while being inserted into the fixing band. It was composed of an inner tube and a reinforcing plate to be inserted between the upper side of the inner tube and the fixing band to protect the inner tube when tightening the upper part of the fixing band with bolts and nuts.

Conventional underground buried pipe connecting device configured as described above was able to solve the existing connection anxiety, which was the same as simply inserting the underground buried pipe to both sides of the connecting pipe by fastening the upper side of the fixing band with bolts and nuts. When the inner tube is tightened with a bolt and a nut to the upper side of the fixing band into which the inner tube is inserted, the shape of the inner tube is twisted or deformed due to the fixing band that is tightened.

The configuration to solve such a problem was to insert a reinforcing plate between the fixing band and the inner tube, but the reinforcing plate should not only be configured to cover the open upper portion of the fixing band, but also the reinforcing plate Since it is simply inserted between the inner tube and the fixing band, the reinforcing plate moves when the fixing band is tightened with bolts and nuts, and the bottom of the reinforcing plate and the inner diameter of the fixing band do not form a garden due to the thickness of the reinforcing plate. There is still a problem that itself is twisted or deformed, as well as the pressure on the outer diameter surface of the inner tube is not uniform, there was also a problem that the deformation of the inner tube and underground buried pipe.

In addition, in the underground buried pipe connecting device composed of a fixed band, an inner pipe and a reinforcing plate, the underground buried pipe inserted into both inner sides of the inner pipe is prevented from being separated from the inner pipe during a continuous underground buried pipe connection. Although the fixing protrusions were formed on the inner side or the reinforcing plate, the fixing protrusions formed on the inside of the fixing band or the fixing protrusions formed by bending both ends of the reinforcing plate form the underground buried pipe when the underground buried pipe is inserted into both sides of the inner pipe. Since it is to maintain the already protruding form to support, there was an uncomfortable and cumbersome problem of inserting the underground buried pipe into the inner pipe while avoiding each fixed projection.

Therefore, the object of the present invention developed to solve the conventional problems as described above form a reinforcing piece integrally with the fixing band on one side of the upper portion of the fixing band tightened by bolts and nuts, both sides of the fixing band on the other side By forming the fixing protrusions integrally to the underground buried pipe connecting device can be configured only by the inner tube and the fixing band without a separate reinforcing plate, the reinforcing piece provided between the inner tube and the upper side of the fixing band is formed integrally with the fixing band. This prevents deformation of the reinforcement plate or the inner tube when tightening the fixing band with bolts and nuts, and also integrates the fixing protrusions on the upper both sides of the fixing band to prevent the underground buried pipe from being separated. When inserting the buried pipe into the inner pipe, it prevents interference of the fixing protrusion and at the same time, the fixing protrusion gradually decreases when tightening the fixing band with bolts and nuts. And it can support the underground buried pipe, thereby providing a underground buried pipe connecting device to make it easier and faster to insert and fix the underground buried pipe to both sides of the inner pipe.

The purpose of the present invention is the inner tube is formed with a partition wall in the inner center and the underground buried pipe is inserted into both sides, the waterproof packing block is inserted between the inner pipe and the underground buried pipe to prevent water from penetrating into the underground buried pipe; In the underground buried pipe connection device consisting of a fixing band for tightening the upper part formed separately while receiving the inner tube with bolts and nuts, the reinforcing piece is fixed while integrally forming a reinforcing piece on the upper side of the fixing band. It can be achieved by forming the underground buried pipe connecting device so that the fixing protrusion formed on both sides of the other side of the fixing band is lowered to both sides of the reinforcing piece when the fixing band is formed to be smaller than the total length of both sides of the band, and the fixing band is tightened with the bolt and nut. .

At this time, when the reinforcing piece is formed integrally with the other side of the fixing band to form a stepped to tighten the fixing band when the reinforcing piece is inserted into the step, it is preferable to configure the bottom surface of the reinforcing piece and the inner diameter surface of the fixing band to form a garden.

The underground buried pipe connecting device according to the present invention forms a reinforcing piece integrally formed on one side of the upper part of the fixed band fastened by the bolt and the nut so that the underground buried pipe connecting device can be constituted by only the inner pipe and the fixed band without a separate reinforcing plate. It is possible to prevent deformation of the reinforcement plate or inner tube when tightening the fixing band with bolts and nuts, as well as to form the fixing projections that prevent the separation of underground buried pipes on both sides of the upper part of the fixing band. When inserting the pipe into the inner tube, it prevents the interference of the fixing projection and tightens the fixing band with bolts and nuts, and the fixing projection comes down to support the underground buried pipe, thereby allowing the underground buried pipe to both sides of the inner pipe. The effect is to make insertion and fixing easier and faster.
