この発明は長大かつ大口径の地中埋設管の基礎定着方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for anchoring a long, large-diameter underground pipe.
近事、汚水処理あるいは廃棄物処理等の設備建設に際し
て長大かつ大口径の管を、内部を中空にして埋設する例
が見られ、その円滑な施工方法が望まれている。Recently, when constructing facilities for sewage treatment, waste treatment, etc., there have been cases in which long, large-diameter pipes are buried with hollow interiors, and a smooth construction method is desired.
この発明は上記事情に鑑み開発されたものである。This invention was developed in view of the above circumstances.
以下、図示した実施の態様にもとずいて説明する。The following description will be made based on the illustrated embodiment.

る。1 shows a buried pipe, the bottom of which is formed into a funnel shape with a packer insertion hole 2 at the tip, the bottom periphery is extended, and a number of holes 11 are bored on the peripheral side. There is.
この埋設管１を予め掘削された掘削孔３に挿入する。This buried pipe 1 is inserted into a pre-drilled excavation hole 3.
そして底部附近の地中にたまつているスライスをポンプ

定する。As shown in FIG. 2, this packer 4 has a cylindrical body with a hemispherical tip, and a hole 5 is bored at a predetermined location on the circumferential side of the packer 4, and the hole 5 is closed on the surface of the packer rubber. 6 is fixed thereto, and a rod 7 is fixed upwardly on the upper end. After inserting the above packer into the insertion hole 2, water or compressed air is introduced into the packer 4 through the opening 7 from the top.
When the inner space 8 is filled, the packer rubber 6 is pushed outward and expanded to close the packer insertion hole 2. Next, with the packer insertion hole 2 closed, a grout pipe 9 is inserted into the excavated hole 3 around the buried pipe 1, and mortar grout 10 is injected from the grout vibe 9, and the buried pipe 1 is inserted into the outer periphery and around the buried pipe 1. The buried pipe 1 is fixed by passing through a hole 11 bored on the circumferential side of the end and filling the bottom with mortar grout 10.

を円滑におこなうことができる。In addition, after fixing the buried pipe 1, the packer 4 may be pulled out, or as the case may be, the upper part from the position of the vibe joint 12 may be removed, and the lower part may be left as is. As described above, when a large-diameter hollow construction pipe is buried in a pre-drilled hole, the hole for inserting the hole drilled in the bottom of the hole for slime treatment can be easily closed by the hole drill.
During grout injection, it is possible to completely prevent grout such as mortar from entering the pipe through the holes, and construction can be carried out smoothly.

に出来るものである。And the hollow construction pipe has a bottom part with a hole for inserting a patch car,
A circumferential surface of the lower end is provided to surround this bottom, and a large number of holes are bored in the circumferential surface of the lower end, so that when grout is injected, the grout can be smoothly injected from the holes to the bottom. Since it is groutable, it is possible to reliably grout not only the outer periphery of the hollow pipe but also the bottom, making the foundation more reliable and strong.
