する場合に用いられている工法である。[Prior Art] Conventionally, methods for laying underground pipes such as water and sewage pipes include trenchless methods and trenchless methods. The cut-and-cover method involves excavating the soil from the ground to the pipe installation point, digging a trench, laying the pipe in the trench, and then backfilling the trench.It is popular because it is simple and economical. This is a construction method commonly used. On the other hand, the trenchless construction method involves digging a hole directly into the soil without digging a trench as in the trenchless construction method, and moving the pipe along with the excavation of the hole. This method is used when laying underground pipes in places where excavation is difficult.
開削工法によつて、道路に埋設管を敷設する方
法について、図面を参照しながら説明する。 A method for laying underground pipes on roads using the cut-and-cover method will be explained with reference to drawings.
第４図に示すように、道路１を横断して開削溝
２を掘る。次いで、開削溝２内に埋設管３を敷設

戻す。 As shown in FIG. 4, an open trench 2 is dug across the road 1. Next, the buried pipe 3 is laid in the cut-and-cut groove 2. To connect the pipes, a trench 4 is made in the trench 2 at the pipe connection portion, and the buried pipes 3 are connected within the trench 4 by welding or the like. Then, the cut groove 2 is backfilled.
［発明が解決しようとする課題］
しかしながら、上述した何れの工法によつて
も、金属製の埋設管を使用する場合には、管同士
の接続が運搬等の面で種々の問題を有していた。[Problems to be Solved by the Invention] However, with any of the above-mentioned construction methods, when underground metal pipes are used, the connection between the pipes has various problems in terms of transportation, etc. Ta.
そこで、金属製の埋設管の代りに、ポリエチレ
ン等の樹脂管を使用することができれば、埋設管
の敷設作業が大幅に軽減されるが、樹脂管の強度
に制約があるので、樹脂管の使用範囲は限られて
いた。 Therefore, if it were possible to use resin pipes such as polyethylene instead of metal buried pipes, the work of laying buried pipes would be greatly reduced, but since the strength of resin pipes is limited, the use of resin pipes is The scope was limited.
従つて、この発明の目的は、ポリエチレン等の
樹脂管の使用範囲の拡大を図ることにある。 Therefore, an object of the present invention is to expand the range of use of resin pipes such as polyethylene.

徴を有するものである。[Means for Solving the Problems] The present invention involves laying a foamed resin molded block having a resin tube forming hole underground, and then inserting the resin tube forming hole into the resin tube forming hole of the block. It is characterized in that a resin film is lined from one end to the other end, and then the resin film is cured.
次に、この発明の、埋設管の敷設方法の一実施
態様を図面を参照しながら説明する。 Next, an embodiment of the buried pipe laying method of the present invention will be described with reference to the drawings.

A resin pipe is formed on the inner surface of the resin pipe forming hole 4A of the block 4. That is, as shown in FIG. 1, the reversing machine 5 is fixed to one end of the resin tube forming hole 4A. Reversing machine 5
has a reel 7 on which a bag-shaped polyethylene resin covering material 6 is wound. A thermosetting adhesive is applied to the inner surface of the covering material 6. Covering material 6
One end is fixed to one end of the resin tube forming hole 4A. Air is forced into the covering material 6 from an air compressor 8. As a result, the covering material 6 comes into close contact with the inner surface of the swollen resin tube forming hole 4A. Covering material 6
is the reel 7 toward the other end of the resin tube forming hole 4A.

Let it harden. As a result, the resin tube forming hole 4A of the foamed resin molding block 4
A resin pipe 10 is formed inside. The resin pipe 10 is
Since the surrounding area is covered with the foamed resin molded block 4, the compressive strength is high.
