Description

本発明は、測量杭等の杭打ち込み用の穴あけ治具と、その穴あけ治具を用いる杭打ち込み用穴あけ方法に関する。   The present invention relates to a drilling jig for driving a pile such as a surveying pile and a drilling method for driving a pile using the drilling jig.

固い地盤に測量杭を打ち込む場合、従来は、大ハンマーやかけや（大型の木槌）により鉄ピンを先に打ち込んで、穴を確保した上で、その後、測量杭を打ち込むのが一般的である。   Conventionally, when driving a surveying pile into hard ground, it is common to drive a steel pin first with a large hammer, hook or large-sized mallet to secure a hole, and then drive the surveying pile. is there.

また、特許文献１において、容易且つ迅速にマーキングポイントに測量杭を打設し得る測点杭打ち装置が提案される。
この測点杭打ち装置は、測量ポールの下端部に、測量杭を装填し得る杭装填空間の形成された杭ホルダーを設け、測量ポールにガイド空間を形成すると共に、そのガイド空間に、ハンマーを杭装填空間との間で移動自在に設け、測量ポールの上端に、所定の測量機器のターゲットと成り得る測量用反射器を設けた構成である。 Moreover, in patent document 1, the surveying pile driving device which can drive a surveying pile to a marking point easily and rapidly is proposed.
In this surveying pile driving device, a pile holder having a pile loading space in which a surveying pile can be loaded is provided at the lower end of the surveying pole, a guide space is formed in the surveying pole, and a hammer is placed in the guide space. The surveying reflector is provided so as to be movable between the pile loading spaces, and a surveying reflector that can be a target of a predetermined surveying instrument is provided at the upper end of the surveying pole.

しかし、従来のように、大ハンマーやかけやにより鉄ピンを打ち込む際、精度が必要となり、打ち直し等の手戻りが生じる可能性が高い。
そして、大ハンマーやかけやを使用することにより、打ち損ねによる災害事例もみられ、安全上にも問題があった。
また、鉄ピンを打ち込む際、低姿勢となるため、作業者の負担も大きかった。 However, when the iron pin is driven by a large hammer or a hook as in the prior art, accuracy is required, and there is a high possibility that rework such as reworking will occur.
In addition, the use of large hammers and hooks resulted in accidents due to failure, and there were safety issues.
In addition, when placing an iron pin, the posture is low, so the burden on the operator is large.

また、特許文献１の測点杭打ち装置は、測量ポール、測量杭装填空間の形成された杭ホルダー、測量ポールのガイド空間、ハンマー、測量用反射器を備える特殊なものであり、鋼製が複雑で高価なものである。   In addition, the surveying pile driving device of Patent Document 1 is a special one including a survey pole, a pile holder in which a survey pile loading space is formed, a guide space for the survey pole, a hammer, and a survey reflector. It is complicated and expensive.

本発明の課題は、測量杭等の杭を打ち込むための穴あけにおいて、大ハンマーやかけやが不要で、杭打ち込み精度を確保して、手戻りを無くし、作業効率を向上することである。   It is an object of the present invention to eliminate the need for a large hammer or hook in drilling a pile such as a surveying pile, to ensure pile driving accuracy, eliminate rework, and improve work efficiency.

FIG.

以下、図を参照して本発明を実施するための形態を詳細に説明する。
（実施形態）
図１は本発明を適用した杭打ち込み用穴あけ治具の一実施形態の概略構成を示すもので、杭打ち込み用穴あけ治具は、図１（ａ）に示す穴あけ部材１と、図１（ｂ）に示す叩き込み部材２とからなる。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment)
FIG. 1 shows a schematic configuration of an embodiment of a pile driving drilling jig to which the present invention is applied. The pile driving drilling jig includes a drilling member 1 shown in FIG. And a hitting member 2 shown in FIG.

穴あけ部材１は、図１（ａ）に示すように、管体１ａの一端に鉄ピン状部１ｂを一体化して備える。
すなわち、この穴あけ部材１は、ガス管による管体１ａの一端に、金テコの先端を切断した部材２ｂ（図１（ｂ）の仮想線参照）による鉄ピン状部１ｂが溶接されたものである。 As shown in FIG. 1A, the hole-piercing member 1 includes an iron pin-like portion 1b integrated with one end of a tubular body 1a.
That is, this punching member 1 is formed by welding an iron pin-like portion 1b by a member 2b (see the phantom line in FIG. 1B) obtained by cutting the tip of a gold lever to one end of a tubular body 1a made of a gas pipe. is there.

叩き込み部材２は、図１（ｂ）に示すように、穴あけ部材１の管体１ａの内部に挿入可能な棒体２ａからなる。
すなわち、この叩き込み部材２は、金テコの先端切断部材２ｂが切断されたもので、棒体２ａの他端にヘラ部２ｃが備えられている。 As shown in FIG. 1 (b), the hitting member 2 includes a rod 2 a that can be inserted into the tube 1 a of the drilling member 1.
That is, the hammering member 2 is obtained by cutting a tip cutting member 2b of a gold lever, and a spatula portion 2c is provided at the other end of the rod body 2a.

図２は杭打ち込み用穴あけ治具（穴あけ部材１と叩き込み部材２）を用いる杭打ち込み用穴あけ方法を示すもので、先ず、図２（ａ）に示すように、地盤に鉄ピン状部１ｂを下にして穴あけ部材１を作業員が手で持って立てるとともに、その穴あけ部材１の管体１ａ内に上方から、叩き込み部材２の棒体２ａを作業員が手で持って挿入する。   FIG. 2 shows a pile driving drilling method using a pile driving drilling jig (a punching member 1 and a hammering member 2). First, as shown in FIG. 2 (a), an iron pin-shaped portion 1b is formed on the ground. The operator holds the drilling member 1 downward by hand and inserts the rod body 2a of the hammering member 2 by hand into the tube 1a of the drilling member 1 from above.

次に、図２（ｂ）に示すように、叩き込み部材２の棒体２ａを作業員が手で持って、穴あけ部材１の管体１ａ下部内の鉄ピン状部１ｂの頭部を叩くことによって、地盤に穴あけ部材１の鉄ピン状部１ｂを所定深さまで打ち込んでいく。   Next, as shown in FIG. 2 (b), the operator holds the rod 2 a of the hitting member 2 by hand and hits the head of the iron pin-like portion 1 b in the lower part of the tube 1 a of the drilling member 1. Thus, the iron pin-like portion 1b of the drilling member 1 is driven into the ground to a predetermined depth.

その後、地盤から穴あけ部材１を抜いて、その地面に残された穴に図示しない測量杭の下端部を挿入して、測量杭を設置する。
なお、測量杭に限らず他の杭を設置してもよい。 Thereafter, the drilling member 1 is pulled out from the ground, and the lower end portion of the surveying pile (not shown) is inserted into the hole left on the ground to install the surveying pile.
In addition, you may install other piles not only a survey pile.

以上、実施形態の杭打ち込み用穴あけ治具、及びその穴あけ治具を用いる杭打ち込み用穴あけ方法によれば、穴あけ部材１が管体１ａの一端に一体化して鉄ピン状部１ｂを備えて、叩き込み部材２が杭１の管体１ａ内に挿入可能で、鉄ピン状部１ｂを叩くための棒体２ａを備え、地盤に鉄ピン状部１ｂを下にして穴あけ部材１を立て、その穴あけ部材１の管体１ａ内に叩き込み部材２の棒体２ａを挿入して、その棒体２ａで鉄ピン状部１ｂを叩くことにより地盤に穴あけ部材１を打ち込むことができる。   As described above, according to the pile driving drilling jig of the embodiment and the pile driving drilling method using the drilling jig, the drilling member 1 is integrated with one end of the tubular body 1a and includes the iron pin-shaped portion 1b. The striking member 2 can be inserted into the pipe body 1a of the pile 1 and is provided with a rod body 2a for striking the iron pin-like portion 1b. The drilling member 1 can be driven into the ground by inserting the rod 2a of the hitting member 2 into the tube 1a of the member 1 and hitting the iron pin-like portion 1b with the rod 2a.

従って、大ハンマーやかけやが不要となり、杭打ち込み精度も確保でき、手戻りが無くなり、杭打ち込みの作業効率を向上させることができる。
また、大ハンマーやかけやが不要となることで、関連災害も無くなり、安全面も改善することができる。
さらに、穴あけ部材１の打ち込みも、図２に示したように、直立姿勢で行なえることから、作業者の負担も軽減することができる。 Therefore, a large hammer or a hook is not necessary, pile driving accuracy can be ensured, reworking is eliminated, and work efficiency of pile driving can be improved.
In addition, by eliminating the need for large hammers and hooks, related disasters can be eliminated and safety can be improved.
Furthermore, since the punching member 1 can be driven in an upright posture as shown in FIG. 2, the burden on the operator can be reduced.

（変形例）
以上の実施形態においては、金テコを利用して穴あけ部材と叩き込み部材を作製したが、本発明はこれに限定されるものではなく、管体の先端に鉄ピン状のものを一体化して、その管体に挿入する棒体を使用してもよい。
また、その他、具体的な細部構造等についても適宜に変更可能であることは勿論である。 (Modification)
In the above embodiment, a punching member and a striking member were produced using a gold lever, but the present invention is not limited to this, and an iron pin-shaped one is integrated at the tip of the tubular body, A rod inserted into the tube may be used.
In addition, it is needless to say that other specific detailed structures can be appropriately changed.
