本考案は、掘削現場の地中埋設物の状況を探査するために使用する探査棒に関 し、特に探査作業の省力化を図ったものである。 The present invention relates to an exploration rod used for exploring the condition of an underground buried object at an excavation site, and is particularly aimed at labor saving of exploration work.
【０００２】[0002]
従来、掘削現場の地中埋設物の状況把握のために、長めの鋼管に略Ｔ字形に取 っ手を設けた探査棒を地中に挿入していた。挿入に際しては、軽く地面に穴を開 け、この穴に探査棒の先端を差し込んで探査棒の先端を安定させながら、探査棒 の略Ｔ字形の取っ手を回して探査棒を回転させながら地中に差し込んでいた。 また、この探査棒は、必要に応じて連結して深い箇所まで探査できるようにな っていた。 Conventionally, in order to grasp the status of underground buried objects at the excavation site, an exploration rod with a T-shaped handle on a long steel pipe was inserted into the ground. When inserting, make a hole in the ground lightly and insert the tip of the probe into this hole to stabilize the tip of the probe. Was plugged into. In addition, the exploration rods could be connected as needed to explore deep areas.
【０００３】[0003]
しかし、従来の探査棒による探査作業は、人手により地中に探査棒を差し込む ため、かなりの労力を必要とする重労働であった。特に、探査範囲が広く、多数 の探査棒を差し込む必要がある場合、又は探査棒の周囲に粘土質の土が重く付着 して身動きできない状態になる場合等は、従来の探査棒による探査作業は大変で あった。 そこで、本考案は、探査棒の地中への挿入作業を楽に行なえる探査棒を提供す ることを目的とする。 However, the conventional exploration work using the exploration rod was a heavy labor that required considerable labor because the exploration rod was manually inserted into the ground. Especially when the exploration range is wide and a large number of exploration rods need to be inserted, or when the clayey soil is heavy around the exploration rods and it becomes impossible to move, the conventional exploration work with exploration rods is not recommended. It was tough. Therefore, an object of the present invention is to provide an exploration rod that can be easily inserted into the ground.

The injection nozzle 40 is integrally formed with a cylindrical upper end and a tapered lower end, a thread groove is provided on the inner peripheral surface of the cylindrical portion of the upper end, and a screw type is provided at the tip of the hollow steel pipe 10. It can be attached to. Further, a thin through hole 40 a communicating with the hollow portion 10 a of the hollow steel pipe 10 is formed in the tapered portion of the injection nozzle 40. Further, the thin through holes 40a are provided with through holes 40b in a suitable radial pattern at the periphery so that the jetted water can flow out to the tip and the periphery.
【００１０】 また、中空鋼管１０の中間部分には、中空鋼管１０を中心にして二重円筒状に 、側壁が肉厚で短めの円筒形に形成された止め部材５０が設けられている。この 止め部材５０は、上方からの重り部材６０の落下衝撃に耐えられるように溶接等 でしっかりと固定されている。 一方、中空鋼管１０の止め部材５０と取っ手２０との間には、中空鋼管１０を 中心にして、二重円筒状に長めの円筒形に形成された重り部材６０が設けられて いる。この重り部材６０の円筒内面は、中心の中空鋼管１０の外周面に少し間隙 を有して二重円筒状にはめられており、中空鋼管１０に沿って重り部材６０が自 然降下できるようになっている。Further, in the middle portion of the hollow steel pipe 10, there is provided a stop member 50 having a double cylindrical shape with the hollow steel pipe 10 as a center and a side wall formed in a thin and short cylindrical shape. The stopper member 50 is firmly fixed by welding or the like so as to withstand a drop impact of the weight member 60 from above. On the other hand, between the stop member 50 of the hollow steel pipe 10 and the handle 20, there is provided a weight member 60 formed in a double-cylindrical elongated cylinder centering on the hollow steel pipe 10. The inner surface of the cylinder of the weight member 60 is fitted into the outer peripheral surface of the central hollow steel pipe 10 in a double cylinder shape with a slight gap so that the weight member 60 can naturally descend along the hollow steel pipe 10.

A mold wheel or the like may be interposed. Further, the cylindrical shapes of the stop member 50 and the weight member 60 are each formed into a cylindrical shape having the same diameter, and the peripheral wall of the cylindrical shape is formed thick so that the impact force when the weight member 60 descends is reduced. The stop member 50 can be sufficiently received.
【００１２】 このようにして、埋設物探査時には、中空鋼管１０の取っ手２０に設けたホー ス連結部材３０に給水ホースＢを連結し、さらに、中空鋼管１０の先端に上記構 成の噴射ノズル４０を取り付けることにより、給水ホースＢから高圧水を供給し て先端の噴射ノズル４０から水を噴射することができる。 併せて、重り部材６０を止め部材５０に降下衝突させることにより、地中に中 空鋼管１０からなる探査棒Ａを挿入し易くすることができる。In this way, at the time of exploring a buried object, the water supply hose B is connected to the hose connecting member 30 provided on the handle 20 of the hollow steel pipe 10, and the tip of the hollow steel pipe 10 is further connected to the injection nozzle 40 having the above-described structure. By attaching, the high-pressure water can be supplied from the water supply hose B and the water can be jetted from the jet nozzle 40 at the tip. At the same time, the weight member 60 is caused to collide with the stop member 50 in a descending manner, so that it is possible to easily insert the exploration rod A made of the hollow steel pipe 10 into the ground.
【００１３】 本考案は、上記実施例に限定されるものではなく、例えば、本実施例では中空 鋼管１０の端部に取っ手２０を設けるとともに、取っ手２０にホース連結部材３ ０を取り付け、取っ手２０及びホース連結部材３０を介して中空鋼管１０に連通 する貫通孔を設ける構成としたが、取っ手２０を中空鋼管１０の側面に設けると ともに、ホース連結部材３０を直接中空鋼管１０に連結できるようにしても構わ ない。 また、噴射ノズル４０を中空鋼管１０の先端に予め一体に形成しておいても構 わない。 また、本考案の止め部材５０及び重り部材６０の構成は、探査棒の地中への挿 入部分が中空管でない棒状のものに使用しても構わない。The present invention is not limited to the above embodiment. For example, in the present embodiment, the handle 20 is provided at the end of the hollow steel pipe 10, the hose connecting member 30 is attached to the handle 20, and the handle 20 is attached. The through hole communicating with the hollow steel pipe 10 via the hose connecting member 30 is provided. However, the handle 20 is provided on the side surface of the hollow steel pipe 10 so that the hose connecting member 30 can be directly connected to the hollow steel pipe 10. It doesn't matter. Further, the injection nozzle 40 may be formed integrally with the tip of the hollow steel pipe 10 in advance. Further, the structure of the stopper member 50 and the weight member 60 of the present invention may be used for a rod-shaped member in which the portion of the probe rod inserted into the ground is not a hollow tube.
