Recently, underground construction work has been carried out in various parts of the country. Such a cable is buried underground after being protected by a protective tube. In order to bury the protective tube underground, a construction is used in which a pipe groove is excavated, a protective tube containing a cable is piped therein, and then backfilled with earth and sand generated by excavation of the pipe groove. When the construction is interrupted for any reason, temporary burial is performed at the end of the protection tube, and when the construction is resumed, the temporary burial is dug to perform the piping work again.

Since (15) is mounted, it is possible to prevent the protection tube (1) from being damaged by an excavator such as a yumbo. Also, the earth and sand (14) is sandproof and waterproof as described above.
Excavation is easy because (12) prevents entry between the pipes and the protective pipe (1)
Can be dug without damaging it.

In the present embodiment, the protection pipe provided in the pipe groove (7)
(1) is similar to that of the previous embodiment by the nozzle (5, 6).
The bundles are bundled into three stages, two stages and two stages, and are stacked in three stages in nozzle units. The shift width is about 50 cm for each step, or the distance between the nozzles (usually 4 m). By shifting each stage in this way, when the work is resumed and the pipe connection is performed from the lower front stage, the pipe connection work is facilitated without interference with the upper tube.

ことが出来るので作業がし易い。According to the present invention, since the pipe is not exposed to the ground at the temporarily buried portion, there is no risk of damaging the pipe, and waste such as cutting off the margin of the pipe can be eliminated. In addition, since the tube terminals are collectively covered with sandproof and waterproof bags,
Sediment does not enter the inside of the pipe or between the pipes, excavation work is easy when resuming construction, and the pipe end can be cleaned without soil, etc., and construction can be resumed promptly Therefore, the workability is improved. In particular, when a protective plate is placed, there is no damage caused by civil engineering machines such as yumbo and power shovels when excavating, and the end of the pipe can be easily identified,
After that, it can be carefully drilled, so that the sandproof waterproof bag and the pipe end will not be damaged. Even if the sand-proof waterproof bag is torn, if the plug is inserted into the end of the pipe, earth and sand and water will not enter the protective pipe, and construction can be started immediately. The plug can be removed simply by pulling out the plastic sheet, so that the work is easy.
