Description of the Related Art In recent years, pipes for laying communication cables and power cables underground have increased in number of pipes to be buried on the same route. ing. 2. Description of the Related Art Conventionally, when laying hard polyvinyl chloride pipes or the like in multiple stages, a method using a pipe pillow has been adopted. In this method, first lay sand at the bottom of the trench,
After leveling, pipe pillows for placing pipes are arranged at, for example, 1 m intervals. The pipes are laid on top of them, and the pipe pillows are further stacked, and the pipes are laid repeatedly, whereby the pipes are assembled in multiple stages.

問題がある。このため掘削溝の底に砂を敷き、念入りに
整地する必要があった。However, since the size of the pipe pillow in the pipe direction is small, for example, about 75 mm, if there is any unevenness (unevenness) at the bottom of the excavation groove, the pipe pillow tends to tilt when installed. There is also a problem that the pipe is easily laid down when laying the pipe. For this reason, it was necessary to spread sand on the bottom of the excavation trench and carefully level the ground.

る。When the lowermost pipe pillows are arranged at regular intervals at the bottom of the excavation groove, it is determined whether or not the pipe pillows are arranged at a predetermined interval, or are arranged straight along the pipe installation route. There was also a problem that it was difficult to confirm whether or not there was.
Particularly when the pipe is a flexible pipe, if the pipe pillow is not installed straight, the pipe is meandered and laid, and as a result, there is a problem in that the cable has a poor lineability.

接していない状態を含むものとする。In order to achieve this object, an underground pipeline according to the present invention has a large number of nozzles of a required length having grooves formed therein for accommodating a half circumference of a pipe, and the grooves are continuous. A pipe having a shorter length than the nozzle, in which a long pipe is laid along the groove, and a concave portion for accommodating a half circumference of the pipe is formed on the upper and lower surfaces thereof. Pillows, at predetermined intervals in the longitudinal direction of the tube, to arrange so that the lower surface side recess covers the tube, and to lay a long tube using the upper surface side recess of the tube pillow as a guide, It is characterized in that pipes are laid in a plurality of stages by repeating at least once. Here, the term “arranged with the end surfaces aligned” includes not only a case where the end surfaces of the nozzles are in contact with each other but also a state where the nozzles are close but not in contact with each other.

Since it does not occur, the leveling of the bottom of the excavation trench can be simplified.
Further, since the nozzles can be linearly arranged only by arranging the end faces so that the grooves are continuous, it is easy to lay the pipes straight.

As shown in (a) and (e), a large number of nozzles 2 are arranged at the bottom of the excavation groove with their end faces abutted so that the grooves 4 are continuous. Since the nozzle 2 has an appropriate length and width, if the bottom surface of the excavation groove is made substantially flat, the nozzle 2 does not tilt or fall. Therefore, it is not necessary to lay the foundation sand on the bottom of the excavation groove as in the related art, and it is possible to reduce not only the cost of the sand itself but also the cost of transporting and laying the sand.

In addition to this, since the nozzle 2 may be arranged so that the grooves 4 are continuous with the end faces aligned, it is easy to lay straight along the route and check whether or not the straight laying is performed. Is also easy. In particular, when laying a flexible pipe, if the nozzle 2 is installed straight, the straightness of the flexible pipe can be ensured, so that the cable permeability is improved.

Although the fitting concave portion and the fitting convex portion were used for coupling, the coupling of these members was performed by forming a vertical through hole in each member and inserting a pin there. Is also good. In any case, by providing the connecting portion with the pipe pillow at the interval at which the pipe pillow is to be installed in the nozzle installed at the lowermost stage, the pipe pillow can be firmly installed at an accurate interval. The material of the nozzle, the pillow, and the restraining member is desirably resin from the viewpoint of ease of construction and the like, but may be concrete or the like. Further, when the laying route of the pipeline is bent, one side of the end face of the nozzle may be aligned and the other side may be opened. Also in this case, the effects of the present invention can be obtained.
