Description

本考案は、地盤に埋設された杭を引き抜くための杭の引抜き治具に関するものである。   The present invention relates to a pile pulling jig for pulling out a pile embedded in the ground.

従来、地盤に埋設した杭を引き抜くには、特許文献１に記載されているように、杭の周壁回りの地盤と杭下部の地盤との縁切り作業を、高圧水噴射用の配管および縁切り用のワイヤで行うものが知られている。また、図４（Ａ）に示すように、埋設した杭１１が連結部材で繋いだ繋ぎ物である場合には、最初の１本目の杭１２は地表に近いのでその杭１２の上端部に引上ワイヤ１４などを掛けてクレーン等で引き出すことも周知である。   Conventionally, in order to pull out a pile buried in the ground, as described in Patent Document 1, the edge cutting operation between the ground around the peripheral wall of the pile and the ground below the pile is performed by using pipes for high pressure water injection and edge cutting. What is done with wire is known. In addition, as shown in FIG. 4A, when the buried pile 11 is a connecting object connected by a connecting member, the first first pile 12 is close to the ground surface, so it is pulled to the upper end of the pile 12. It is also well known that the upper wire 14 or the like is hung and pulled out by a crane or the like.

特開２００４−３０８３３８号公報JP 2004-308338 A

しかし２本目の杭１３を引き抜くには、容易ではない。例えば、図５に示すように、引上ワイヤ１４の先端部に輪を形成して、これをケーシング１５の先端部に付けた突起部１５ａに引っ掛けて、図６に示すように、このケーシング１５とともに前記引上ワイヤ１４を掘削孔６に沈降させる。   However, it is not easy to pull out the second pile 13. For example, as shown in FIG. 5, a ring is formed at the tip of the pull-up wire 14, and this is hooked on a protrusion 15a attached to the tip of the casing 15, and as shown in FIG. At the same time, the pulling wire 14 is allowed to settle in the excavation hole 6.

そして、前記２本目の杭１３の中間程度までケーシング１５が降下したところで停止させ、前記引上ワイヤ１４においてその先端部の輪１４ａを緩めておいて、前記ケーシング１５を引き抜く。その後、前記引上ワイヤ１４の輪１４ａを杭１３の上部に巻き付かせ、この引上ワイヤ１４をクレーン等で引き上げれば、杭１３を引き抜くことができる。   Then, the casing 15 is stopped when the casing 15 is lowered to the middle of the second pile 13, the wheel 14 a at the tip of the pull-up wire 14 is loosened, and the casing 15 is pulled out. Then, if the ring | wheel 14a of the said pull-up wire 14 is wound around the upper part of the pile 13, if this pull-up wire 14 is pulled up with a crane etc., the pile 13 can be pulled out.

しかしながら、前述の特許文献１の場合には、高圧水用配管や高圧水用のコンプレッサーなどを装備しなければならないのでコストが嵩み、更には、縁切りワイヤーも杭にセットすることが実際には困難を伴うものである。   However, in the case of the above-mentioned Patent Document 1, it is necessary to equip a high-pressure water pipe, a high-pressure water compressor, and the like, which increases the cost. It is difficult.

更に、前述の図５，図６に示すような方法においては、実際には前記引上ワイヤ１４が硬くて思うように緩めることができず、ケーシング１５とともに前記引上ワイヤ１４が上に移動してしまい、２本目の杭１３の引き抜きに失敗することの方が多い。そこで、本考案に係る杭の引抜き治具は、このような課題を解決するために提案されたものである。   Furthermore, in the method shown in FIGS. 5 and 6, the pulling wire 14 is actually hard and cannot be loosened as expected, and the pulling wire 14 moves upward together with the casing 15. In many cases, the second pile 13 fails to be pulled out. Then, the pile extraction jig | tool which concerns on this invention is proposed in order to solve such a subject.

本考案に係る杭の引抜き治具の上記課題を解決して目的を達成するための要旨は、地盤に埋設された杭を該杭の端部にワイヤを巻き付かせて引き上げる治具であって、筒状のケーシングと、該ケーシングの先端部に輪部分を巻き付けて一端部を地上の引上げ手段に係合させる投げ縄状の引上ワイヤと、前記ケーシングの先端部の爪状の突起部分に係合させ且つ環状部材と係合される切断可能な紐部材と、前記環状部材に挿通されるワイヤであってそのワイヤの一端が前記引上ワイヤの輪部分の一部に係止されワイヤの他端が地上に至るまで配設されるもので前記引上ワイヤの輪部分の押し下げをする引下ワイヤとからなることである。   The gist for solving the above-mentioned problems of the pile pulling jig according to the present invention is to achieve a purpose by pulling up a pile embedded in the ground by winding a wire around the end of the pile. A cylindrical casing, a lasso-shaped pulling wire that wraps a ring portion around the tip of the casing and engages one end with the pulling means on the ground, and a claw-like protrusion at the tip of the casing A severable string member engaged and engaged with the annular member, and a wire inserted through the annular member, one end of the wire being locked to a part of the ring portion of the pull-up wire The other end is arranged until reaching the ground, and is composed of a pull-down wire that pushes down the ring portion of the pull-up wire.

また、本考案に係る杭の引抜き治具の上記課題を解決して目的を達成するための要旨は、地盤に埋設された杭を該杭の端部にワイヤを巻き付かせて引き上げる治具であって、 筒状のケーシングと、該ケーシングの先端部に輪部分を巻き付けて一端部を地上の引上げ手段に係合させる投げ縄状の引上ワイヤと、前記輪部分に着脱自在に装着されるもので前記輪部分に位置固定して取り付ける係止部材と該係止部材に固定される逆爪部材とでなる持上り防止部材とからなることである。   Moreover, the gist for achieving the object by solving the above-mentioned problem of the pile pulling jig according to the present invention is a jig for pulling up a pile buried in the ground by winding a wire around the end of the pile. A tubular casing, a lasso-shaped pulling wire in which a ring portion is wound around the tip of the casing and one end is engaged with a pulling means on the ground, and the ring portion is detachably mounted. That is, it is composed of a locking member that is fixedly attached to the ring portion and attached, and a lifting prevention member that is a reverse claw member fixed to the locking member.

本考案の杭の引抜き治具によれば、投げ輪状のワイヤの輪部分を、確実に地盤中の杭の先端部にセットすることができるようになる。また、持上り防止部材によっても、掘削孔の周壁に逆爪部材が引っかかるようになり、投げ縄状のワイヤの輪部分を杭の途中にセットすることができる。こうして、地盤の掘削孔に深く埋設された杭を確実に引き抜くことができるものである。   According to the pile drawing jig of the present invention, the ring portion of the lasso-like wire can be reliably set on the tip portion of the pile in the ground. Further, the lifting prevention member also causes the reverse claw member to be caught on the peripheral wall of the excavation hole, and the ring portion of the lasso-like wire can be set in the middle of the pile. In this way, the pile deeply buried in the excavation hole in the ground can be reliably pulled out.

本考案に係る杭の引抜き治具１は、図１に示すように、ワイヤによる投げ縄の輪部分がケーシングなどに引っかかって上に持ち上げられることが無いようにして、引き抜き対象の杭の先端部へ確実にセットできるようにすることである。   As shown in FIG. 1, the pile pulling jig 1 according to the present invention is configured so that the lasso ring portion of the wire is not caught on the casing or the like and lifted up, and the tip of the pile to be pulled out It is to ensure that it can be set.

前記杭の引抜き治具１の構成は、図１と図４とに示すように、地盤１５に埋設された杭１３を該杭１３の端部１３ａに引上ワイヤ１４を巻き付かせて引き上げる治具であって、筒状のケーシング２と、該ケーシング２の先端部２ａに輪部分１４ａを巻き付けて一端部１４ｂを地上の引上げ手段（クレーンなど、図示せず）に係合させる投げ縄状の引上ワイヤ１４とがある。   As shown in FIGS. 1 and 4, the pile pulling jig 1 has a structure in which a pile 13 embedded in the ground 15 is wound around an end portion 13 a of the pile 13 by winding a pulling wire 14. A lasso-like member having a cylindrical casing 2 and a loop portion 14a wound around the tip portion 2a of the casing 2 to engage one end portion 14b with a pulling means (such as a crane, not shown) on the ground. There is a pull-up wire 14.

更に、前記ケーシング２の先端部２ａの爪状の突起部分２ｂに係合させ且つ環状部０．材３と係合される切断可能な紐部材４と、前記環状部材３に挿通されるワイヤであってそのワイヤの一端５ａが前記引上ワイヤ１４の輪部分１４ａの一部１４ｃに係止されワイヤの他端５ｂが地上に至るまで配設されるもので前記引上ワイヤ１４の輪部分１４ａの押し下げをする引下ワイヤ５とからなる。   Further, it is engaged with the claw-like protruding portion 2b of the front end portion 2a of the casing 2 and the annular portion 0. A severable string member 4 engaged with the material 3 and a wire inserted through the annular member 3, and one end 5 a of the wire are engaged with a part 14 c of the ring portion 14 a of the pull-up wire 14. The other end 5b of the wire is disposed until reaching the ground, and includes a pulling wire 5 that pushes down the ring portion 14a of the pulling wire 14.

前記引上ワイヤ１４は、図示のように先端部が投げ縄のように輪部分１４ａが形成されているものである。この引上ワイヤ１４の輪部分１４ａにおける先端部（ヘビ口）１４ｃには、引下ワイヤ５の一端５ａが係止されている。この引下ワイヤ５を地上で引くと、環状部材３を挿通しているので、ケーシング２の突起部分２ｂの上下方向の位置が変わらなければ、前記一端５ａが下に押し下げられ、それにより前記輪部分１４ａも引きずられて下がる。この第１実施例では、従来例におけるケーシング１５の突起部１５ａは、不要である。前記引下ワイヤ５で、図１に示す状態を維持しながら掘削孔に降下させることができるからである。   As shown in the drawing, the pull-up wire 14 has a ring portion 14a formed with a tip portion like a lasso. One end 5a of the pull-down wire 5 is locked to the tip end portion (snake port) 14c of the ring portion 14a of the pull-up wire 14. When the pull-down wire 5 is pulled on the ground, the annular member 3 is inserted, so that if the vertical position of the protruding portion 2b of the casing 2 does not change, the one end 5a is pushed down, whereby the wheel The part 14a is also dragged down. In the first embodiment, the protrusion 15a of the casing 15 in the conventional example is not necessary. This is because the pull-down wire 5 can be lowered into the excavation hole while maintaining the state shown in FIG.

前記環状部材３は、前記引下ワイヤ５の一端５ａを下げるように引下ワイヤ５の引張方向を変更する支点となるものである。また、前記環状部材３は、金属製の強度的に強いリングである。これは、前記引下ワイヤ５を強く引き上げるときに、前記紐部材４を切断させるためのものである。   The annular member 3 serves as a fulcrum for changing the pulling direction of the pulling wire 5 so as to lower one end 5a of the pulling wire 5. The annular member 3 is a metal strong ring. This is for cutting the string member 4 when the pull-down wire 5 is pulled up strongly.

前記紐部材４としては、例えば、金属製若しくは合成樹脂製の環状部材３によって切断可能な細い番線を使用する。また、引下ワイヤ５は、地上からの操作により、引上ワイヤ１４の輪部分１４ａをケーシング２の上昇に抗して、下に押しとどめるようにする金属製のワイヤである。   As the string member 4, for example, a thin wire that can be cut by an annular member 3 made of metal or synthetic resin is used. The pull-down wire 5 is a metal wire that allows the ring portion 14a of the pull-up wire 14 to be pushed down against the ascent of the casing 2 by an operation from the ground.

このようにして構成した実施例１に係る杭の引抜治具１によれば、図１および図４を参照して説明すると、まず、図４（Ａ），（Ｂ）に示すように、地上に近い杭１２の上端部に引上ワイヤ１４の輪部分１４ａを掛けて、この杭１２をクレーン等で引き上げる。   According to the pile drawing jig 1 according to the first embodiment configured as described above, with reference to FIGS. 1 and 4, first, as shown in FIGS. 4A and 4B, the ground A ring portion 14a of the pull-up wire 14 is hung on the upper end portion of the pile 12 close to, and the pile 12 is pulled up with a crane or the like.

次に、図１に示す杭の引抜治具１を、ケーシング２の先端部２ａを下にして掘削孔６に挿入する。前記ケーシング２の先端部２ａが杭１３の上部から中間部に至るところで、ケーシング２の降下を停止させる。そして、引上ワイヤ１４を緩めて、引下ワイヤ５を地上にて図１に示すように、引き上げる。すると、前記環状部材３によって引下ワイヤ５の一端５ａが下に引かれ、これに係合する引上ワイヤ１４の輪部分１４ａの全体が引き下げられる。   Next, the pile drawing jig 1 shown in FIG. 1 is inserted into the excavation hole 6 with the front end 2a of the casing 2 facing down. When the tip 2a of the casing 2 reaches from the upper part of the pile 13 to the middle part, the descent of the casing 2 is stopped. Then, the pulling wire 14 is loosened and the pulling wire 5 is pulled up on the ground as shown in FIG. Then, one end 5a of the pull-down wire 5 is pulled down by the annular member 3, and the entire ring portion 14a of the pull-up wire 14 engaged therewith is pulled down.

その後、前記引下ワイヤ５を強く地上で引いて、紐部材４を切断する。こうして、ケーシング２を地上に引き上げる。杭１３の上部に前記引上ワイヤ１４が残され、該引上ワイヤ１４をクレーン等で引き上げる。すると、図４（Ｃ）に示すように、杭１３の上部に引上ワイヤ１４の輪部分１４ａが巻き付いて、この杭１３を引き上げることができる。このようにして、引上ワイヤ１４の輪部分１４ａを確実に地下に埋まった杭１３に括（くく）り付けることができるようになる。   Thereafter, the pulling wire 5 is pulled strongly on the ground to cut the string member 4. Thus, the casing 2 is pulled up to the ground. The pulling wire 14 is left on the top of the pile 13, and the pulling wire 14 is pulled up with a crane or the like. Then, as shown in FIG. 4C, the ring portion 14 a of the pulling wire 14 is wound around the upper portion of the pile 13, and the pile 13 can be pulled up. In this way, the ring portion 14a of the pull-up wire 14 can be securely attached to the pile 13 buried underground.
