Description

[Detailed description of the invention] The present invention is convenient for burying multiple flexible pipes, such as corrugated plastic pipes and corrugated metal pipes, in a straight line by arranging them in the ground at predetermined intervals. This relates to burying aids.

In recent years, corrugated flexible pipes made of synthetic resin with spiral or independent arc corrugation processing have come to be used in various fields such as civil engineering and architecture because they can be easily bent and laid in bent places. Became.

This corrugated flexible tube is usually wound around a drum or rolled up into a bundle for transportation.

For this reason, when we tried to extend the pipeline at the installation site, it was difficult to lay it straight away due to its bending tendency, and the extended pipeline ended up meandering considerably.

For this reason, if a trench is dug in the ground and a plurality of corrugated flexible pipes are laid parallel to each other at a predetermined distance within the premises,
This meandering phenomenon causes adjacent tubes to become entangled with each other.

Furthermore, when attempting to draw a cable or the like into the laid corrugated flexible pipe, an excessive pulling tension is required due to the above-mentioned curvature of the pipe.

Therefore, if the length of the flexible conduit is shortened, problems such as the need to install multiple manholes arise.

Therefore, in order to prevent mutual entanglement when a plurality of corrugated flexible pipes are extended, conventionally, as shown in Fig. 1, cut portions 2 that match the outside diameter of the pipes are made at intervals between the pipes laid on the board. Insert the desired number of gauge plates 1 (hereinafter referred to as spacing gauge plates) from directly above the pipe to be laid, and then carefully manually sprinkle earth and sand to a thickness of about 10 crn onto the pipe line that has been laid in alignment so that the spacing gauge plates do not move. They would fix the position of the existing pipeline by applying a lock, then pull out the spacing gauge and move it to the pipeline that was not yet secured with earth and sand, and do the same thing again to bury the entire length.

However, if you try to bury and fix the position of the pipeline after it has been laid using heavy equipment such as a Yunbo instead of relying on hands, the impact of the heavy equipment applying earth and sand will cause the distance between the pre-set interval gauge plate and the pipeline to be fixed. Moreover, this spacing gauge plate is effective in maintaining the distance between the pipes being laid, but is not very effective in correcting meandering in the length direction of the wall pipes. Ta.

The present invention is an auxiliary tool for burying flexible conduits, which was devised by focusing on the drawbacks observed when using conventional spacing gauge plates. At least two of the comb-like objects 7 formed by fixing a plurality of stakes 6 at intervals are connected to at least one comb-like object 7 by the crosspiece 5 which is the back of the comb-like object.
It is characterized in that it is constructed by attaching the tips of the stakes of each comb-like object to the connecting rod 8 of the book at desired intervals so that they are oriented in the same direction.

Next, the usage of the product of the present invention will be explained using an example product.

Figure 2 shows an embodiment of the present invention in which three comb-like objects 7 are fixed to two connecting rods 8 in parallel. As shown in the figure, the bottom of the excavated groove 10 dug between the manholes 9 and 9' is leveled, the flexible tube 3 is extended into the groove, and the auxiliary tool 4 of the present invention is placed on the flexible tube. Cover the flexible pipe from above so that it passes between the piles 6゜6', 6'', and apply moderate pressure to press the flexible pipe against the flat bottom of the excavation trench to align the flexible pipe in the vertical direction. It corrects undulations and also corrects horizontal undulations by inserting it between adjacent piles.

With the flexible conduits arranged in this way, a layer of less sticky sand or the like is placed on top of them to a thickness of about 10 crn to temporarily tighten them.

Then, when this auxiliary tool 4 is pulled out directly above, the sand in the portion of the auxiliary tool 4 other than the pile 6 remains in the trench 1, so that the flexible conduits are maintained in an aligned state.

The auxiliary tool 4 that has been pulled out is moved over the laid pipes in sequence A, B, and C as shown in Figure 3, used as described above, and temporarily buried. Completely bury it, and the burial is completed.

The flexible pipe burying aid of the present invention is manufactured to an appropriate size according to the outer diameter of the flexible pipe to which it is applied. It is preferable to make the space between the comb-like piles about 2 cm wider than the outer diameter of the flexible tube so that it can be easily pulled out.

In addition, the length of the pile 6 that constitutes the comb-like object is such that the tip of the pile is stuck in the bottom of the excavation groove so that the flexible pipe to be applied can be sufficiently fixed, and specifically the outer diameter of the flexible pipe to be applied. It is better to be about 5 crn longer.

Furthermore, if the connecting rod 8 to which the comb-shaped member 7 is attached is made long, it is possible to bury a long distance of pipe at one time, but from the viewpoint of handling, it is appropriate to use a connecting rod 8 of about 3 to 5 m.

Furthermore, if the distance between the combs 7 attached to the connecting rod 8 is too long, it will not be useful for aligning the flexible conduits, so a distance of 1 m is appropriate.

Although the material of the present invention is not particularly specified, it can be manufactured using a rectangular column made of wood, metal, plastic, etc., or a cylindrical metal pipe.

As explained above, the flexible conduit burying aid of the present invention is very useful for aligning and burying flexible conduits with excellent straightness in the horizontal and vertical directions using heavy equipment, and has practical advantages. The value is high.
