【考案の詳細な説明】
・ 産業上の利用分野
本考案は地面よりたて穴を掘削したのち、この
たて穴内においてオーガーを利用して横方向に穴
をあけ、次にこのオーガーの先端側に樹脂管の先
端を繋いでオーガーを後退させながら樹脂管を横
穴内に引き込むときに使用される治具に関するも
のである。[Detailed explanation of the invention] - Industrial application field This invention involves drilling a vertical hole from the ground, then drilling a hole horizontally within the vertical hole using an auger, and then inserting a resin pipe into the tip of the auger. This relates to a jig that is used when pulling a resin pipe into a horizontal hole while connecting the tips of the auger and retracting the auger.
・ 従来技術とその問題点
管を穴内に引き込むときに、この管に加工する
ことなく牽引ワイヤー等を管に繋ぐ方法として
は、第3図に示すようなケーブルグリツプが公知
である。・Prior art and its problems A cable grip as shown in FIG. 3 is known as a method for connecting a traction wire or the like to a pipe without processing the pipe when the pipe is drawn into a hole.
しかし、このケーブルグリツプはグリツプ力も
高く、使用性も良いが、反面土中に掘削した穴内
に管を引き込むときに、この穴と管との外径を可
及的に接近させて、管と穴との間に隙間が生じな
いようにする埋設工法を採用するときには、ケー
ブルグリツプの部分が管の外径よりも可成り大き
くなつて引き込みに際して穴を崩したり、穴の径
を大きくして隙間を発生させてしまうという欠点
がある。 However, although this cable grip has a high gripping force and is easy to use, when pulling the pipe into a hole excavated in the soil, it is necessary to bring the outside diameter of the hole and the pipe as close as possible. When using a burying method that prevents gaps between the pipe and the hole, the cable grip portion becomes considerably larger than the outer diameter of the pipe, which may cause the hole to collapse or the diameter of the hole to be increased. This has the disadvantage of creating gaps.
上記欠点を解決する一つの手段としては管の先
端内にインサート工具を嵌合してこのインサート
工具に牽引具を繋ぐという方法も考えられるが、
インサート工具を管の先端内に嵌合して牽引力に
対抗するためには管とインサート工具との摩擦力
を高める必要があり、このようにすると樹脂管の
場合にはインサート工具を挿入した部分のみの外
径が他に比較して太くなり、他の管と接合するよ
うな場合にこの太くなつたことが障害となること
が多い。 One possible solution to the above drawback is to fit an insert tool into the tip of the tube and connect a traction tool to this insert tool.
In order to fit the insert tool into the tip of the pipe and resist the traction force, it is necessary to increase the frictional force between the pipe and the insert tool, and in the case of resin pipes, only the part where the insert tool is inserted The outer diameter of the tube is thicker than other tubes, and this thickening often becomes a problem when connecting to other tubes.
又、樹脂管を土中の穴内に引き込む際に、管の
先端側の外周面に最も傷が付き易く、この傷が他
の管と接合した場合に気密性を阻害する。 Furthermore, when a resin pipe is drawn into a hole in the ground, the outer circumferential surface on the tip side of the pipe is most likely to be damaged, and this damage will impede airtightness if it joins with another pipe.

部分においてその外径が変らず、よつて樹脂管
をサービスチー等の分岐部材に接合する際に何
等支障が起らない。a) The insert has a step consisting of a large diameter part and a small diameter part, which increases the frictional force in the large diameter part to connect the insert and the resin pipe, and prevents the outer diameter of the resin pipe from increasing in the small diameter part. Therefore, the outer diameter of the resin pipe does not change at the joining portion, and therefore, no problem occurs when joining the resin pipe to a branch member such as a service cable.

周面に傷がつく心配がなく、よつてこの樹脂管
をサービスチー等の分岐部材に接合した際に気
密性が悪くなることがない。b A protective cap is placed over the tip of the resin pipe to protect it when it is being drawn in, so there is no need to worry about damaging the outer circumferential surface of the joint of the resin pipe during the process of drawing it in, making it easier to carry the resin pipe to the service center. The airtightness will not deteriorate when joined to a branch member such as.
