Description

[Detailed description of the device]

[0001]

[Industrial field of use] The present invention is installed to prevent the supply of gas pipes, water pipes and other pipes buried in roads from being interrupted during the repair work so that the supply to users will not be delayed. The present invention relates to temporary piping for bypass.

[0002]

2. Description of the Related Art Generally, a PVC pipe, a metal pipe or the like is used as a bypass temporary pipe for repairing a buried pipe, and is arranged along a road. In particular, if the temporary pipeline for bypass is installed across the road, or if it is installed across the part that will be the passage of the vehicle such as in front of the garage, the temporary pipeline for bypass will interfere with the running of the vehicle. Then, as shown in FIG. 4 (a), a groove b is excavated in the road surface a, and the bypass temporary pipe c is positioned in the groove b.
The open upper portion of the groove b was closed with an iron plate d or the like.

However, excavating a groove for temporary bypass piping is a very troublesome work.
Moreover, it is necessary to refill the groove after the construction is completed, which is a waste of construction. Therefore, the present invention proposes a bypass temporary pipe which does not require excavation of a road crossing groove.

[0004]

DISCLOSURE OF THE INVENTION A bypass temporary pipe for road burying pipe construction according to the present invention comprises a tubular temporary member, a flat portion having a predetermined length, and a connecting portion for connecting the temporary member to an end portion. Formed, and also composed of a flat tube with a predetermined rigidity,
A flat pipe is laid at a crossing point on the road, and a tubular temporary member is connected to the flat pipe.
Further, in particular, in the temporary pipe for bypass, a reinforcing partition is provided inside the flat pipe to provide a predetermined rigidity, or a side plate edge of the flat pipe is provided with a collar plate for fastening to a road surface. To do.

[0005]

When a flat pipe is simply placed on the road surface and used as a bypass temporary pipe line that crosses a road or the like, it is not necessary to excavate a groove on the road, and there is no hindrance to the passage of vehicles.

[0006]

EXAMPLE An example of the present invention will be described below. The bypass temporary pipe according to the present invention is composed of a tubular temporary member 1 and a flat pipe 2, and the tubular temporary member 1 is a vinyl chloride pipe, a metal pipe, or a pipe body determined according to an object of pipe use, and a pipe as appropriate. The connecting portion 11 is formed at the end portion so that a pipe line having an arbitrary length can be formed.

The flat pipe 2 is a main pipe portion 21 having a flat trapezoidal cross section.
And a connecting pipe portion 22 connected to both ends of the main pipe portion 21, the main pipe portion 21 has a length corresponding to the width of the road to be installed and used, and a reinforcing partition portion 23 is provided inside the external pipe. A collar plate 24 is attached to the side edge, and a fastening hole 25 is formed in the collar plate 24. The connecting pipe portion 22 has a tapered shape and is provided at its end with a connecting portion 26 corresponding to the connecting portion 11 of the tubular temporary member 1.

Then, the flat pipe 2 is placed on the road surface a at a passage point of the vehicle such as the crossing portion of the inner road A of the temporary pipe for bypass or the front of the garage B, etc. Corresponding fastening holes are dug, and the flat pipe 2 is firmly fixed to the road surface a with a pin C or the like, and the temporary member 1 is connected with this to form a temporary pipe for bypass, which is used.

Therefore, it is not necessary to excavate a groove for crossing a road to install the temporary pipe, and naturally there is no need to backfill, and the installation work of the temporary pipe is simplified.

The present invention is not limited to the above embodiment, and the structure itself can be arbitrarily determined as long as the flat pipe for crossing the road can withstand the weight of the material.

[0011]

As described above, according to the present invention, the temporary pipe for bypass is composed of the tubular temporary member and the flat pipe having the predetermined length and the rigidity, and the flat pipe is provided at the crossing point of the road.
When installing the bypass temporary pipe, there is no need to excavate a groove in the road, and there is no hindrance to the passage of vehicles, and the installation work of the bypass temporary pipe is simplified.
