のである。2. Description of the Related Art The above-mentioned underground buried pipe unit is constructed by stacking an underground buried pipe unit in which a plurality of underground buried pipes are supported by a supporting member by, for example, expansion, on an existing underground buried pipe unit. It is configured so that a desired number of underground pipes can be installed. If a plurality of underground pipes are bundled by the support member and are arranged in the arrangement route, the underground pipes can be conveyed one by one or arranged in the arrangement route. Not only is it advantageous in terms of transportation, but it is also possible to shorten the installation period of underground pipes as compared with other products. However, in the above-mentioned configuration, backfilling soil is insufficiently filled between the support members constituting the underground buried pipe unit, a void is apt to occur, and the pipe body has its own weight and soil load and live load (vehicle load etc.) after being buried. ), There is a problem in that a bending phenomenon in which the tube shaft center direction intermediate portion drastically hangs down, and as a solution to this, there is one disclosed in Japanese Patent No. 3023664, for example. This is to provide a plurality of fixing pipes for fixing and holding a plurality of burying pipes in parallel with each other at a predetermined interval, at a predetermined interval of the burying pipes.
The space between the fixing pipes in the vertical direction between the embedding pipes is closed by a filling member made of expanded polyethylene.

不都合があった。According to the above construction, it is troublesome and troublesome to carry out the work of concentrating and holding a plurality of embedding pipes in parallel at a predetermined interval using a plurality of spacers and a binding band. Not only that, but because the bundled embedding pipes are tightened tightly with a binding band so that they do not come apart, the filling member must be installed between the embedding pipes located above and below before tightening. The sex was deteriorated. Further, the filling member can hold the gaps between the pipes at a predetermined distance to prevent bending, but the filling member sandwiching the bending prevention for the buried pipe located at the lowermost position between the upper and lower pipes is used. There was an inconvenience that could not be done. Further, since the filling member is configured to have a length that fills the voids over the entire space between the spacers, even if it is expanded polystyrene, the weight of the entire unit is dramatically increased and the handleability is deteriorated. Not only that, but there is a disadvantage that the material cost increases. Further, since the filling member is simply sandwiched between the upper and lower burying pipes, if the fastening by the binding band is loosened, the filling member may come off during transportation or construction, and again. The detached filling member had to be sandwiched between the upper and lower buried pipes, which were heavy, and it was difficult to handle. Further, not only the work of filling the gap between the buried pipes that are adjacent to each other in the left-right direction constituting the underground buried pipe unit with soil or the like but also if the soil filling work is not ensured, There was an inconvenience that troubles such as the ground sinking occurred.
