特開2004−332392号公報JP 2004-332392A

しかしながら、特許文献1の土壌採取管装置は、土壌取込孔全閉状態において、土壌採取目標位置以外の地中で内管内(土壌収容空間)から外部に汚染水が漏れて土壌採取目標位置以外の場所を汚染してしまう可能性があったり、土壌採取目標位置以外の地中で外部から内管内に地下水が入り込んでしまって土壌採取目標位置の土壌の成分の検査を正確に行うことができない可能性があるといった課題があった。
本発明は、上記課題に鑑みてなされたもので、土壌取込孔の塞がれた状態での内管内と外部との水密性能を維持できる土壌採取管装置を提供する。
However, in the soil sampling tube device of Patent Document 1, in the soil intake hole fully closed state, the contaminated water leaks from the inside pipe (soil accommodating space) to the outside in the ground other than the soil sampling target position, and other than the soil sampling target position. The soil component at the soil sampling target position cannot be accurately inspected because the groundwater may enter the inner pipe from outside in the ground other than the soil sampling target position. There was a problem that there was a possibility.
This invention is made | formed in view of the said subject, and provides the soil sampling pipe | tube apparatus which can maintain the watertight performance of the inner pipe | tube in the state with which the soil intake hole was block | closed, and the exterior.

本発明に係る土壌採取管装置は、周面に開口部を有しロッド部を介した回転駆動力を受けて中心軸線を回転中心として回転可能な外管と、外管の中心軸線と同軸に外管内に設置されて周面に土壌取込孔を有した内管と、内管の土壌取込孔における内管の中心軸線に沿った方向に延長する孔縁より外管の開口部を経由して外管の外周面より外側に突出するように設けられた土壌取込孔塞体と、外管の両端開口を塞ぐ蓋体とを備え、地上からの操作により地中で外管を一方方向に回転させた場合には、土壌取込孔が開口部を介して地中と連通し、地上からの操作により地中で外管を他方方向に回転させた場合には、外管の開口部における外管の中心軸線に沿った方向に延長する開口縁と土壌取込孔塞体とが接触して土壌取込孔が塞がれるように構成された土壌採取管装置において、土壌取込孔の塞がれた状態での内管内と外部との水密性能を維持する水密性能維持部を備えたので、土壌取込孔全閉状態において、土壌採取目標位置以外の地中で内管内から外部に汚染水が漏れて土壌採取目標位置以外の場所を汚染してしまうようなことを防止できる。また、土壌採取目標位置以外の地中で外部から内管内に地下水が入り込んでしまうことを防止できるので、土壌採取目標位置の土壌の成分の検査を正確に行うことができる。
内管は、内管の中心軸線に沿った分割面で2分割以上に分割可能に構成されたので、内管内に採取された土壌を取り出しやすくなり、作業の効率化が図れる。
外管は、土壌取込孔の塞がれた状態を維持するためのロック部を備えたので、地中において土壌採取管装置を移動させる際に土壌取込孔全閉状態を維持でき、土壌採取管装置の移動中に土壌取込孔が開いてしまうことを防止できるので、土壌採取目標位置以外の地中の土壌を内管内に取り込んでしまったり、土壌採取目標位置において内管内に取り込んだ汚染土壌を土壌採取目標位置以外の地中に撒き散らして汚染を拡大させてしまうことを防止できる。
土壌取込孔塞体は、土壌取込孔塞体の縁部から土壌取込孔塞体の中央側に向けて延長する切欠部を備えたので、外管を回転させて土壌取込孔を開閉する際において、外管の回転負荷を軽減できるようになる。
切欠部の長さが、土壌取込孔塞体の板面に切欠部の延長方向に沿って引いた線の長さの1/2以上であるので、外管の回転負荷をより軽減できるようになる。
土壌取込孔塞体は、開口部の他方の孔縁に接触して土壌取込孔を塞ぐ他方の板面とは反対側の一方の板面における縁部が、他方の板面から一方の板面の中央に向けて傾斜する傾斜面に形成されたので、土壌採取管装置の移動中において土壌取込孔が開いてしまうようなことを防止できる。
The soil sampling pipe device according to the present invention has an outer pipe that has an opening on the peripheral surface and receives a rotational driving force via a rod part, and is rotatable about the central axis as a rotation center, and coaxial with the central axis of the outer pipe The inner pipe that is installed in the outer pipe and has a soil intake hole on the peripheral surface, and the opening of the outer pipe from the edge of the hole that extends in the direction along the central axis of the inner pipe in the soil intake hole of the inner pipe And a soil intake hole blocking body provided so as to protrude outward from the outer peripheral surface of the outer pipe, and lid bodies that block the openings at both ends of the outer pipe. When rotating in the direction, the soil intake hole communicates with the ground through the opening, and when the outer tube is rotated in the other direction in the ground by operation from the ground, the opening of the outer tube The soil intake hole is closed by the contact between the opening edge extending in the direction along the central axis of the outer pipe at the section and the soil intake hole blockage. Since the soil sampling tube device has a watertight performance maintaining section that maintains the watertight performance between the inside and outside of the inner tube when the soil intake hole is closed, the soil intake hole is fully closed. It is possible to prevent the contaminated water from leaking from the inner pipe to the outside in the ground other than the sampling target position and contaminating the area other than the soil sampling target position. In addition, since groundwater can be prevented from entering the inner pipe from the outside in the ground other than the soil collection target position, the component of the soil at the soil collection target position can be accurately inspected.
Since the inner pipe is configured to be divided into two or more parts on the dividing plane along the central axis of the inner pipe, it becomes easy to take out the soil collected in the inner pipe, and work efficiency can be improved.
Since the outer pipe has a lock part for maintaining the state where the soil intake hole is blocked, the soil intake hole can be kept fully closed when the soil sampling pipe device is moved in the ground. Since it is possible to prevent the soil intake hole from opening during the movement of the sampling tube device, soil in the ground other than the soil sampling target position is taken into the inner pipe or taken into the inner pipe at the soil sampling target position. It is possible to prevent the contaminated soil from spreading into the ground other than the soil collection target position and spreading the contamination.
Since the soil uptake block has a notch that extends from the edge of the soil uptake block toward the center of the soil uptake block, rotate the outer tube to remove the soil uptake hole. When opening and closing, the rotational load on the outer tube can be reduced.
Since the length of the notch is 1/2 or more of the length of the line drawn along the extending direction of the notch on the plate surface of the soil intake hole blockage, the rotational load of the outer tube can be further reduced. become.
The soil intake hole blocker is in contact with the other hole edge of the opening to block the soil intake hole, and the edge of one plate surface opposite to the other plate surface is Since it was formed in the inclined surface which inclines toward the center of a board surface, it can prevent that a soil intake hole opens during the movement of a soil sampling pipe apparatus.

上記第1の水密性能維持部材61を備えたことにより、土壌取込孔全閉状態において、開口部16の他方の長辺縁16bと土壌取込孔塞体13の他方の板面13bとの間の水密性能を維持できるので、内管12内に対する開口部16の他方の長辺縁16bと土壌取込孔塞体13の他方の板面13bとの間を介した土壌や地下水の出入を防止できる。
また、第2の水密性能維持部材62;62を備えたことにより、後述する土壌取込孔全閉状態において、土壌取込孔18の短辺19a;19bと接する内管12の外周面と外管11の内周面との間の水密性能を維持できるので、内管12内に対する、開口部16の短辺縁16cと土壌取込孔塞体13の辺縁21aとの間、開口部16の短辺縁16dと土壌取込孔塞体13の辺縁22aとの間、蓋体26と外管11の端部開口25との間、蓋体36と外管11の端部開口25aとの間等を介した土壌や地下水の出入を防止できる。
また、第3の水密性能維持部材63を備えたことにより、後述する土壌取込孔全閉状態において、開口部16の長辺縁16aと内管12の外周面との間の隙間を介して連続する内管12の外周面と外管11の内周面との間の水密性能を維持できるので、土壌取込孔全閉状態における開口部16の長辺縁16aと内管12の外周面との間の隙間を介した土壌や地下水の出入を防止できる。
従って、土壌取込孔全閉状態において、土壌採取目標位置50以外の地中で内管12内から外部に汚染土壌や汚染地下水が漏れてしまうことを防止でき、土壌採取目標位置50以外の場所を汚染してしまうようなことを防止できる。また、土壌取込孔全閉状態において、土壌採取目標位置50以外の地中で外部から内管12内に土壌や地下水が入り込んでしまうことを防止でき、土壌採取目標位置50の土壌の成分の検査を正確に行うことができるようになる。
尚、図示しないが、第2の水密性能維持部材62;62が対面する外管11の内周面又は内管12の外周面に当該第2の水密性能維持部材62;62が嵌り込む溝を設ければ、水密性能をより向上できる。この場合、内管12の外周面又は外管11の内周面から突出する第3の水密性能維持部材63及び第2の水密性能維持部材62の突出長さの関係を、第3の水密性能維持部材63の突出長さ<第2の水密性能維持部材62の突出長さとすることで、第2の水密性能維持部材62;62が上述した溝に嵌まり込み、かつ、内管12と外管11とが相対的に回転可能となる好ましい構成を実現できる。

土壌採取管装置1の組付構造を説明する。蓋体26;36のうちの一方の蓋体26と外管11の一方の端部開口25とがねじ連結される。外管11の他方の端部開口25aから挿入された内管12の挿入側先端の管内側に一方の蓋体26の内管回転支持部31の円柱を入れる(はめ込む)。内管12の後端の管内側に他方の蓋体36の内管回転支持部41の円柱を入れた(はめ込んだ)状態で当該他方の蓋体36と外管11の他方の端部開口25aとがねじ連結される。土壌取込孔塞体13が内管12の土壌取込孔18の一方の長辺縁19に取付けられる。以上により、地中に設置された場合に、土壌取込孔塞体13が地中に設置されることで内管12の回転が規制されるとともに外管11に回転力を加えることで外管11が土壌取込孔18を開閉可能に回転する。   The assembly structure of the soil sampling tube device 1 will be described. One lid body 26 of the lid bodies 26; 36 and one end opening 25 of the outer tube 11 are screw-connected. The column of the inner tube rotation support portion 31 of one lid 26 is inserted (inserted) into the inner side of the tube on the insertion side tip of the inner tube 12 inserted from the other end opening 25a of the outer tube 11. In the state where the cylinder of the inner tube rotation support portion 41 of the other lid body 36 is inserted (inserted) inside the tube at the rear end of the inner tube 12, the other end body opening 25a of the other lid body 36 and the outer tube 11 is inserted. And are screwed together. A soil intake hole blocking body 13 is attached to one long edge 19 of the soil intake hole 18 of the inner tube 12. As described above, when installed in the ground, the soil intake hole blocking body 13 is installed in the ground so that the rotation of the inner tube 12 is regulated and the outer tube 11 is subjected to a rotational force to apply the outer tube. 11 rotates so that the soil intake hole 18 can be opened and closed.

図2(a);図3(a)に示すように、土壌採取管装置1は、地中において、ロッド部5を回転させることで外管11を一方方向Aに回転させた場合に、開口部16の一方の長辺縁16aと土壌取込孔塞体13の一方の板面13aとが接触し、土壌取込孔18の開口縁が開口部16の開口縁の内側に位置して土壌取込孔全開状態となる。その後、さらに、外管11を一方方向Aに回転させることで、外管11と内管12とが中心軸線aを回転中心として供回りする。これにより、地中の土壌が土壌取込孔塞体13の他方の板面13bに押圧されて内管12内に取り込まれる。
そして、内管12内に土壌を取り込んだ後、図2(b);図3(b)に示すように、外管11を他方方向Bに回転させた場合に、凹凸係合形態の第1の水密性能維持部材61が凹凸係合して接触することで、土壌取込孔18が外管11の内周面と対向し、内管12の内部空間と外部空間との連通が土壌取込孔塞体13により遮断された土壌取込孔全閉状態となり、内管12内に取り込まれた土壌が外管11及び土壌取込孔塞体13によって外管11の内側に封じ込められた状態となって外管11の周りの地中に流出しないようになる。
As shown in FIG. 2 (a); FIG. 3 (a), the soil sampling tube device 1 opens when the outer tube 11 is rotated in one direction A by rotating the rod portion 5 in the ground. One long side edge 16a of the part 16 and one plate surface 13a of the soil intake hole blocking body 13 are in contact with each other, and the opening edge of the soil intake hole 18 is located inside the opening edge of the opening part 16 and soil. The intake hole is fully open. Thereafter, the outer tube 11 is further rotated in one direction A, so that the outer tube 11 and the inner tube 12 are rotated around the central axis a. As a result, the soil in the ground is pressed by the other plate surface 13 b of the soil intake hole blocking body 13 and taken into the inner tube 12.
And after taking in the soil in the inner tube | pipe 12, when the outer tube | pipe 11 is rotated in the other direction B, as shown to FIG. 2B; FIG. The water-tightness performance maintaining member 61 of the inner tube 12 is in contact with the concave-convex engagement so that the soil intake hole 18 faces the inner peripheral surface of the outer tube 11, and the communication between the inner space of the inner tube 12 and the outer space is the soil intake. A state where the soil intake hole blocked by the hole closing body 13 is fully closed, and the soil taken into the inner pipe 12 is sealed inside the outer pipe 11 by the outer pipe 11 and the soil intake hole closing body 13; Thus, it does not flow out into the ground around the outer tube 11.

自由曲線掘削機2は、図7(a);(b);図9に示すように、ロッド部5と、ロッド部5の先端5tに設けられた掘削ビット6と、ロッド部5の先端部あるいは掘削ビット6に設けられた磁気センサやジャイロセンサなどの位置検出センサ7と、ロッド部5を前後動させたり回転させたりするための駆動装置8とを備える。掘削ビット6は、先端に、中実の円柱の一端開口部が斜めに切り落とされたような楕円傾斜面9を備え、楕円傾斜面9に図外の削岩ビットを有した構成である。また、掘削ビット6は、先端に掘削液噴射孔6dを備え、内部には、掘削液噴射孔6dとロッド部5の内部空間5uとを連通させる掘削液供給路6eを備える。ロッド部5は、掘削が進むに伴って例えば金属円管により形成されるロッド5aを複数個順次継ぎ足して構成される。ロッド5a同士の連結は、例えば、ネジ継手のような図外の連結部材が用いられる。位置検出センサ7は、掘削ビット6の後端側に形成された中空部に埋設される。   As shown in FIGS. 7A and 7B, the free-curve excavator 2 includes a rod portion 5, a drill bit 6 provided at a tip 5 t of the rod portion 5, and a tip portion of the rod portion 5. Alternatively, a position detection sensor 7 such as a magnetic sensor or a gyro sensor provided in the excavation bit 6 and a drive device 8 for moving the rod portion 5 back and forth or rotating it are provided. The excavation bit 6 has a configuration in which an elliptical inclined surface 9 in which one end opening of a solid cylinder is cut off obliquely is provided at the tip, and a rock drill bit (not shown) is provided on the elliptical inclined surface 9. The excavation bit 6 includes an excavation fluid injection hole 6d at the tip, and an excavation fluid supply path 6e that communicates the excavation fluid injection hole 6d with the internal space 5u of the rod portion 5 therein. The rod portion 5 is configured by sequentially adding a plurality of rods 5a formed of, for example, a metal circular pipe as excavation progresses. For the connection between the rods 5a, for example, a connection member (not shown) such as a screw joint is used. The position detection sensor 7 is embedded in a hollow portion formed on the rear end side of the excavation bit 6.

自由曲線掘削機2を用いて、例えば、機械工場のような建屋下の地中や廃棄物処分場跡のような更地下の地中における土壌採取目標位置50での汚染された土壌を採取する第1の土壌採取方法を説明する。
まず、図7に示すように、自由曲線掘削機2を用いて土壌採取目標位置50を通過する掘削孔51を形成する。例えば、掘削ビット6を土壌採取目標位置の深さ位置まで斜め下方向に推進させるようにして斜め下方向に地盤を掘削した後、掘削ビット6を水平方向に推進させるようにして水平方向に地盤を掘削して土壌採取目標位置50を通過する掘削孔51を形成し、その後、掘削ビット6を斜め上方向に推進させるようにして斜め上方向に地盤を掘削して掘削ビット6を地上に出す。
地盤を斜めに掘削する場合には、ロッド部5をロッド部5の中心軸線を回転中心として駆動装置8に設けられた図外のモータのような回転駆動源で回転させることで掘削ビット6を回転させながら掘削ビット6を推進させる。
掘削ビット6の推進方向を変える場合は、ロッド部5を回転させないで、駆動装置8に設けられた図外の油圧シリンダのような押圧装置でロッド部5に推進力を与えて掘削ビット6の楕円傾斜面9に土圧が作用するようにすることで、掘削ビット6の推進方向を変える。これにより、掘削ビット6及びロッド部5を水平方向に移動させることができる。
掘削の際には、ロッド部5の筒内中空部を掘削液の供給管路として利用するので、ロッド部5の後端を図外の掘削液供給装置に繋ぎ、ロッド部5を回転させるとともに、掘削液供給装置からロッド部5の筒内中空部を介して掘削ビット6に掘削液を圧送して供給する。掘削液としては、水、ベントナイト溶液、ポリマー等の安定液等を用いる。これにより、掘削ビット6の掘削液噴射孔6dから地盤に掘削液が噴射されながら掘削ビット6が地盤を掘削する。
そして、掘削が進むのに応じてロッド5aを順次継ぎ足していく動作を繰り返すことにより、土壌採取目標位置50を通過する掘削孔51を形成する。尚、掘削ビット6の位置は、位置検出センサ7からの位置情報により操作者が知ることができ、当該位置情報に基づいて土壌採取目標位置50を通過する掘削孔51を形成できる。
Using the free-curved excavator 2, for example, contaminated soil is collected at a soil collection target position 50 in a subterranean ground such as a machine factory or a underground ground such as a waste disposal site. A first soil collection method will be described.
First, as shown in FIG. 7, the excavation hole 51 passing through the soil sampling target position 50 is formed using the free curve excavator 2. For example, after excavating the ground in an obliquely downward direction by propelling the excavation bit 6 to the depth position of the soil collection target position, the ground in the horizontal direction by propelling the excavation bit 6 in the horizontal direction. Is drilled to form a drilling hole 51 that passes through the soil sampling target position 50, and then the ground is excavated diagonally upward so that the drilling bit 6 is propelled upward, and the drilling bit 6 is brought out to the ground. .
When excavating the ground diagonally, the excavation bit 6 is rotated by rotating the rod portion 5 with a rotational drive source such as a motor (not shown) provided in the drive device 8 around the central axis of the rod portion 5 as the rotation center. The drill bit 6 is propelled while rotating.
When the propulsion direction of the excavation bit 6 is changed, the rod portion 5 is not rotated, and a propulsive force is applied to the rod portion 5 by a pressing device such as a hydraulic cylinder (not shown) provided in the drive device 8 to By making earth pressure act on the elliptically inclined surface 9, the propulsion direction of the excavation bit 6 is changed. Thereby, the excavation bit 6 and the rod part 5 can be moved to a horizontal direction.
At the time of excavation, since the hollow part in the cylinder of the rod part 5 is used as a supply pipe for the drilling liquid, the rear end of the rod part 5 is connected to a drilling liquid supply device (not shown) and the rod part 5 is rotated. The drilling fluid is pumped and supplied to the drilling bit 6 from the drilling fluid supply device through the hollow portion in the cylinder of the rod portion 5. As the drilling fluid, a stable fluid such as water, bentonite solution, or polymer is used. Thereby, the excavation bit 6 excavates the ground while the excavation liquid is jetted from the excavation fluid injection hole 6d of the excavation bit 6 to the ground.
And the excavation hole 51 which passes the soil sampling target position 50 is formed by repeating the operation | movement which adds the rod 5a sequentially as excavation progresses. The position of the excavation bit 6 can be known by the operator from the position information from the position detection sensor 7, and the excavation hole 51 that passes through the soil sampling target position 50 can be formed based on the position information.

図7(a)に示すように、自由曲線掘削機2を用いて土壌採取目標位置50を目標にして掘削を行う。そして、土壌採取目標位置50を通過した地中を掘り抜いた掘削孔51を形成し(図7(b)参照)、その後、掘削孔51の掘削終点から地上に引き出したロッド部5の先端に取付けられていた掘削ビット6を取り外し、代わりに、ロッド部5の先端に土壌採取管装置1を取付ける(図7(c)参照)。そして、土壌採取管装置1の土壌取込孔18を閉じた状態で、土壌採取管装置1を掘削孔51内経由で掘削始点側に戻して土壌採取目標位置50まで移動させる(図7(d)参照)。土壌採取管装置1が土壌採取目標位置50に到達したならば、土壌取込孔18を開く方向(一方方向A)に外管11を回転させることにより、土壌採取目標位置50の土壌を内管12内に取り込む(図7(d)参照)。その後、土壌取込孔18を閉じる方向(他方方向B)に外管11を回転させて土壌取込孔18を閉じて、土壌採取管装置1を掘削孔51経由で掘削始点まで戻して地上に出し、ロッド部5の先端に取付けられていた土壌採取管装置1を取り外す。そして、土壌取込孔塞体13を掴んで、土壌取込孔18が外部に開放される方向に内管12を回転させ、内管12内の土壌を土壌取込孔18及び開口部16を介して取り出す。尚、作業者は図外のモニターに表示される位置検出センサ7からの情報(方位情報、距離情報等)を確認しながら、土壌採取目標位置50への掘削作業、及び、土壌採取目標位置50の土壌を内管12内に取り込む土壌採取作業を行う。   As shown in FIG. 7A, excavation is performed using the free-curve excavator 2 with the soil sampling target position 50 as a target. And the excavation hole 51 which dug the underground which passed the soil sampling target position 50 is formed (refer FIG.7 (b)), Then, it is on the front-end | tip of the rod part 5 pulled out from the excavation end point of the excavation hole 51 to the ground. The attached excavation bit 6 is removed, and instead, the soil sampling pipe device 1 is attached to the tip of the rod portion 5 (see FIG. 7C). Then, with the soil intake hole 18 of the soil collection tube device 1 closed, the soil collection tube device 1 is returned to the excavation start point side via the excavation hole 51 and moved to the soil collection target position 50 (FIG. 7 (d )reference). When the soil sampling pipe device 1 reaches the soil sampling target position 50, the outer pipe 11 is rotated in the direction in which the soil intake hole 18 is opened (one direction A), whereby the soil at the soil sampling target position 50 is 12 (see FIG. 7D). Thereafter, the outer pipe 11 is rotated in the direction of closing the soil intake hole 18 (the other direction B), the soil intake hole 18 is closed, and the soil sampling pipe device 1 is returned to the excavation start point via the excavation hole 51 and put on the ground. The soil sampling tube device 1 attached to the tip of the rod portion 5 is removed. And the soil intake hole obstruction | occlusion body 13 is grasped, the inner pipe | tube 12 is rotated in the direction in which the soil intake hole 18 is opened outside, and the soil in the inner pipe 12 is made to pass through the soil intake hole 18 and the opening 16. Take out through. The operator confirms information (azimuth information, distance information, etc.) from the position detection sensor 7 displayed on the monitor (not shown) while excavating the soil collection target position 50, and the soil collection target position 50. The soil sampling operation for taking the soil into the inner pipe 12 is performed.

図8;9を参照し、第2の土壌採取方法を説明する。
図8に示すように、自由曲線掘削機2のロッド部5の先端5tに設けられた掘削ビット6により、掘削始点から土壌採取目標位置50まで掘削する(図8(a);(b)参照)。その後、掘削ビット6を掘削始点に戻して地上に出した後、ロッド部5の先端5tより掘削ビット6を取り外して、ロッド部5の先端5tに土壌採取管装置1を取付けるとともに、土壌採取管装置1の先端に掘削ビット6を取付ける(図8(c)参照)。そして、掘削ビット6及び土壌採取管装置1を掘削孔51内経由で土壌採取目標位置50まで戻して土壌採取管装置1の内管12の内部に土壌採取目標位置50の土壌を取り込む((図8(d)参照)。その後、土壌採取管装置1を掘削始点まで戻して土壌採取管装置1の内部の土壌を取り出す。この第2の土壌採取方法の場合も、作業者は図外のモニターに表示される位置検出センサ7からの情報(方位情報、距離情報等)を確認しながら、土壌採取目標位置50への掘削作業、及び、土壌採取目標位置50の土壌を内管12内に取り込む土壌採取作業を行う。
尚、第2の土壌採取方法で用いる土壌採取管装置1は、上述した引出部材15の代わりに、図9に示すようなビット側連結部15Aを備えたものを用いる。ビット側連結部15Aは、一端部には、外管11の他方の端部開口25aを塞ぐように当該他方の端部開口25aに取付けられる上記引出部材側蓋体36と同様の蓋体15Xを備え、他端部には、ビット連結部55を備える。ビット連結部55は、掘削ビット6の後端部の管の内周面に形成された雌ねじ部56とねじ結合される雄ねじ部57により形成される。
また、第2の土壌採取方法の場合、ロッド部5の先端5tに土壌採取管装置1及び掘削ビット6を取付けた構成において掘削ビット6の前方地中に掘削液を供給するために、掘削ビット6の掘削液供給路6eと掘削液供給路として利用されるロッド部5の内部空間5uとを連通させるための掘削液供給路を備えた連結部材14及びビット側連結部15Aを使用する。即ち、連結部材14としては、ロッド部5の内部空間5uと内管12の内部空間とに連通する掘削液供給路14eを備えたものを用い、ビット側連結部15Aとしては、内管12の内部空間と掘削ビット6の掘削液供給路6eとに連通する掘削液供給路15eを備えたものを用いる。掘削液供給路15eの途中には、地下水が掘削ビット6の掘削液供給路6eを経由して内管12の内部空間に流入(逆流)するのを防止するための逆止弁15fが設けられる。逆止弁15fの取付容易性からすると、逆止弁15fを、ビット側連結部15Aの掘削液供給路15eの両方の端部のうちのいずれか一方に設けることが好ましいが、ビット側連結部15Aの掘削液供給路15eにおける内管12側に逆止弁15fを設けた場合、内管12の内側に取り込まれた土壌が逆止弁15f内に入り込んで逆止弁15fの故障を誘発する可能性がある。そこで、第2の土壌採取方法では、ビット側連結部15Aの掘削液供給路15eにおける掘削ビット6側の端部に逆止弁取付部が設けられ、逆止弁15fが当該逆止弁取付部に取付けられた構成とした。
以上の構成により、掘削の際には、掘削液が、ロッド部5の内部空間5u、掘削液供給路14e、内管12の内部空間、掘削液供給路15e、掘削液供給路6e、掘削液噴射孔6dを経由して掘削ビット6の前方地中に供給される。そして、掘削液が供給されていない場合には、逆止弁15fが、内管12の内部空間内への地下水の流入を防止する。
第2の土壌採取方法によれば、地中を掘り抜くことができない現場においても土壌を採取することができる。
The second soil sampling method will be described with reference to FIGS.
As shown in FIG. 8, the excavation bit 6 provided at the tip 5t of the rod portion 5 of the free-curve excavator 2 excavates from the excavation start point to the soil sampling target position 50 (see FIGS. 8A and 8B). ). Then, after returning the excavation bit 6 to the excavation start point and taking it out to the ground, the excavation bit 6 is detached from the tip 5t of the rod part 5 and the soil sampling pipe device 1 is attached to the tip 5t of the rod part 5 and the soil sampling pipe A drill bit 6 is attached to the tip of the device 1 (see FIG. 8C). Then, the excavation bit 6 and the soil sampling pipe device 1 are returned to the soil sampling target position 50 via the excavation hole 51 and the soil at the soil sampling target position 50 is taken into the inner pipe 12 of the soil sampling pipe device 1 ((FIG. 8 (d)) After that, the soil sampling tube device 1 is returned to the excavation start point, and the soil inside the soil sampling tube device 1 is taken out. The excavation work to the soil collection target position 50 and the soil at the soil collection target position 50 are taken into the inner pipe 12 while checking the information (direction information, distance information, etc.) from the position detection sensor 7 displayed on Perform soil collection work.
In addition, the soil sampling tube apparatus 1 used with the 2nd soil collection method uses the thing provided with 15 A of bit side connection parts as shown in FIG. 9 instead of the extraction member 15 mentioned above. 15 A of bit side connection parts have the cover body 15X similar to the said extraction member side cover body 36 attached to the said other end part opening 25a so that the other end part opening 25a of the outer tube | pipe 11 may be plugged up in one end part. And the other end portion is provided with a bit connecting portion 55. The bit connecting portion 55 is formed by a male screw portion 57 that is screwed to a female screw portion 56 formed on the inner peripheral surface of the pipe at the rear end portion of the excavation bit 6.
In the case of the second soil collection method, the excavation bit is used to supply the excavation fluid into the ground in front of the excavation bit 6 in the configuration in which the soil sampling pipe device 1 and the excavation bit 6 are attached to the tip 5t of the rod portion 5. The connecting member 14 and the bit side connecting portion 15 </ b> A having the drilling fluid supply passage for communicating the drilling fluid supply passage 6 e with the inner space 5 u of the rod portion 5 used as the drilling fluid supply passage are used. In other words, the connecting member 14 is provided with a drilling fluid supply passage 14e communicating with the internal space 5u of the rod portion 5 and the internal space of the inner tube 12, and the bit side connecting portion 15A includes the inner tube 12 of the inner tube 12. The one provided with the drilling fluid supply passage 15e communicating with the internal space and the drilling fluid supply passage 6e of the drilling bit 6 is used. In the middle of the drilling fluid supply passage 15e, a check valve 15f for preventing the groundwater from flowing into the inner space of the inner pipe 12 via the drilling fluid supply passage 6e of the drilling bit 6 is provided. . From the viewpoint of ease of mounting of the check valve 15f, it is preferable to provide the check valve 15f at either one of both ends of the drilling fluid supply passage 15e of the bit side connecting portion 15A. When the check valve 15f is provided on the inner pipe 12 side in the drilling fluid supply passage 15e of 15A, the soil taken inside the inner pipe 12 enters the check valve 15f and induces a failure of the check valve 15f. there is a possibility.

When the drilling fluid is not supplied, the check valve 15f prevents the groundwater from flowing into the inner space of the inner pipe 12.
According to the second soil collection method, soil can be collected even at a site where the underground cannot be excavated.

第1の土壌採取方法では、土壌採取目標位置50の土壌を土壌採取管装置1で採取した後に土壌採取管装置1を掘削孔51の掘削始点側に引き戻して掘削始点の開口より地上に引き出したが、第3の土壌採取方法として、土壌採取目標位置50の土壌を土壌採取管装置1で採取した後に土壌採取管装置1を掘り抜いた掘削孔51の掘削終点側に押し進めて掘削終点の開口より地上に押し出してもよい。当該第3の土壌採取方法は、土壌採取目標位置50から掘削終点までの距離が、土壌採取目標位置50から掘削始点までの距離よりも短い場合に効果的である。   In the first soil collection method, after the soil at the soil collection target position 50 is collected by the soil collection pipe device 1, the soil collection pipe device 1 is pulled back to the excavation start point side of the excavation hole 51 and pulled out from the opening of the excavation start point to the ground. However, as a third soil collection method, after the soil at the soil collection target position 50 is collected by the soil collection pipe device 1, the soil collection pipe device 1 is pushed forward to the excavation end point side of the excavation hole 51 to open the excavation end point. You may push out more to the ground. The third soil collection method is effective when the distance from the soil collection target position 50 to the excavation end point is shorter than the distance from the soil collection target position 50 to the excavation start point.

Embodiment 4
The soil sampling tube device 1 of the fourth embodiment is a soil sampling tube device 1 having a configuration in which only the watertight performance maintaining unit 60 is excluded from the soil sampling tube device 1 shown in FIG. ) In FIG. 10; FIG. 11 includes an inner tube 12 composed of two or more split members that can be divided into two or more parts by a dividing surface 65 along the central axis a. .
As shown in FIG. 10 and FIG. 11, when the dividing surface 65 is formed of a stepped surface and the half member 66; 66 divided into two is used as the split member, each half member 66; 66 is centered on the central axis a. If the split surface 65 having the shape to be rotated is provided, the inner pipe 12 can be formed by the half member 66; 66 having the same shape, which is advantageous in terms of manufacturing cost.
According to the soil sampling tube device 1 of the fourth embodiment, by dividing the inner tube 12, it becomes easy to take out the soil collected in the inner tube 12, and work efficiency can be improved.

尚、実施形態4の土壌採取管装置1に、上述した水密性能維持部60、後述するロック部70、スリット付き土壌取込孔塞体13、傾斜面付き土壌取込孔塞体13、スリット及び傾斜面付き土壌取込孔塞体13のうちの1つ以上の構成を加味した土壌採取管装置1としてもよい。   In addition, the water sampling performance maintenance part 60 mentioned above, the locking part 70 mentioned later, the soil intake hole obstruction body 13 with a slit, the soil intake hole obstruction body 13 with an inclined surface, a slit, It is good also as the soil sampling tube apparatus 1 which considered one or more structures in the soil intake hole obstruction body 13 with an inclined surface.

実施形態5
実施形態5の土壌採取管装置1は、前提構成の土壌採取管装置1に、図12;図13に示すような、ロック部70を有した外管11を備えた構成とした。
ロック部70は、土壌取込孔塞体13と外管11の開口部16の開口縁とが接触して土壌取込孔18が塞がれた状態を維持するために、土壌取込孔塞体13の他方の辺縁22a側の辺縁部71が入り込む溝72により形成される。溝72は、開口部16の長辺縁16bと外管11の他方の端部開口25a側に位置する開口部16の短辺縁16d(引出部材15に近い側の短辺縁)との境界部に形成されるものであって、長辺縁16bより長辺縁16bに対して一直線状に延長する延長縁75と、当該延長縁75と平行に対向する対向縁76と、延長縁75の先端と対向縁76の先端とを繋いで溝底を形成する底縁77とにより形成される。溝72の幅寸法は、溝72に入り込んだ土壌取込孔塞体13が外管11の周方向に動いてがたつかないように、土壌取込孔塞体13の厚さ寸法に近似した適性値に設定される(例えば、溝72の幅寸法が土壌取込孔塞体13の厚さ寸法よりも数mm大きい程度に設定される)。
実施形態5によれば、外管11を他方方向Bに回転させた場合に、開口部16の他方の長辺縁16bと土壌取込孔塞体13の他方の板面13bとが接触することで、土壌取込孔全閉状態となり、この土壌取込孔全閉状態においてロッド部5を掘削始端側に引っ張って外管11を掘削始端側に引っ張ることにより、土壌取込孔塞体13の辺縁部71が溝72内に入り(図13(b)参照)、土壌取込孔塞体13が外管11の周方向に回転しないようになるので、土壌採取管装置1は土壌取込孔全閉状態にロックされることになる。
実施形態5によれば、外管11がロック部70を備えるので、地中において土壌採取管装置1を移動させる際に土壌取込孔全閉状態を維持でき、土壌採取管装置1の移動中に土壌取込孔18が開いてしまうようなことを防止できる。よって、土壌採取目標位置50以外の地中の土壌を内管12内に取り込んでしまったり、土壌採取目標位置50において内管12内に取り込んだ汚染土壌を土壌採取目標位置50以外の地中に撒き散らして汚染を拡大させてしまうことを防止できる。
Embodiment 5
The soil sampling tube device 1 of Embodiment 5 is configured to include the outer tube 11 having a lock portion 70 as shown in FIG. 12 and FIG.
In order to maintain the state where the soil intake hole 18 is blocked by the contact between the soil intake hole blocking body 13 and the opening edge of the opening portion 16 of the outer tube 11, the lock portion 70 is closed. It is formed by a groove 72 into which the edge portion 71 on the other edge 22a side of the body 13 enters. The groove 72 is a boundary between the long side edge 16b of the opening 16 and the short side edge 16d of the opening 16 located on the other end opening 25a side of the outer tube 11 (short side edge closer to the drawing member 15). An extended edge 75 extending in a straight line from the long side edge 16b to the long side edge 16b, an opposing edge 76 facing the extended edge 75 in parallel, and an extended edge 75 It is formed by a bottom edge 77 that connects the tip and the tip of the opposite edge 76 to form a groove bottom. The width dimension of the groove 72 approximated the thickness dimension of the soil intake hole blocking body 13 so that the soil intake hole blocking body 13 entering the groove 72 would not move and rattle in the circumferential direction of the outer tube 11. It is set to an appropriate value (for example, the width dimension of the groove 72 is set to be about several mm larger than the thickness dimension of the soil intake hole blocking body 13).
According to the fifth embodiment, when the outer tube 11 is rotated in the other direction B, the other long side edge 16b of the opening 16 and the other plate surface 13b of the soil intake hole blocking body 13 are in contact with each other. In this state, the soil intake hole is fully closed, and in this soil intake hole fully closed state, the rod portion 5 is pulled toward the excavation start end side and the outer tube 11 is pulled toward the excavation start end side. Since the edge portion 71 enters the groove 72 (see FIG. 13B) and the soil intake hole blocking body 13 is prevented from rotating in the circumferential direction of the outer tube 11, the soil sampling tube device 1 takes in the soil intake. It will be locked in the hole fully closed state.
According to the fifth embodiment, since the outer tube 11 includes the lock portion 70, when the soil sampling tube device 1 is moved in the ground, the soil intake hole fully closed state can be maintained, and the soil sampling tube device 1 is moving. It is possible to prevent the soil intake hole 18 from being opened. Therefore, soil in the ground other than the soil collection target position 50 is taken into the inner pipe 12, or contaminated soil taken into the inner pipe 12 at the soil collection target position 50 is put into the ground other than the soil collection target position 50. It is possible to prevent spreading and spreading the contamination.

尚、上述した第2の土壌採取方法で用いる土壌採取管装置1としては、土壌採取管装置1を掘削始点から土壌採取目標位置50に移動する際に土壌採取管装置1を土壌取込孔全閉状態にロックするための溝72aにより構成されたロック部70を設けることが好ましい。この場合の溝72aは、図12に示すように、例えば、開口部16の長辺縁16bと外管11の一方の端部開口25側に位置する開口部16の短辺縁16c(連結部材14に近い側の短辺縁)との境界部に形成されるものであって、長辺縁16bより長辺縁16bに対して一直線状に延長する延長縁75aと、当該延長縁75aと平行に対向する対向縁76aと、延長縁75aの先端と対向縁76aの先端とを繋いで溝底を形成する底縁77aとにより形成される。この場合、土壌取込孔全閉状態においてロッド部5を押して外管11を押すことにより、土壌取込孔塞体13の他方の辺縁21a側の辺縁部71aが溝72a内に入り、土壌取込孔塞体13が外管11の周方向に回転しないようになるので、土壌採取管装置1は土壌取込孔全閉状態にロックされることになる。よって、土壌採取管装置1の移動中に土壌取込孔18が開いてしまうようなことを防止できる。   In addition, as the soil sampling tube device 1 used in the second soil sampling method described above, when the soil sampling tube device 1 is moved from the excavation start point to the soil sampling target position 50, the soil sampling tube device 1 is used as a whole soil intake hole. It is preferable to provide a lock portion 70 constituted by a groove 72a for locking in the closed state. As shown in FIG. 12, the groove 72a in this case includes, for example, a long side edge 16b of the opening 16 and a short side edge 16c of the opening 16 positioned on the one end opening 25 side of the outer tube 11 (connecting member). 14 is formed at a boundary portion between the long side edge 16b and the long side edge 16b. The extended edge 75a extends in a straight line from the long side edge 16b to the long side edge 16b, and is parallel to the extended edge 75a. And a bottom edge 77a that forms a groove bottom by connecting the tip of the extended edge 75a and the tip of the counter edge 76a. In this case, the edge portion 71a on the other edge 21a side of the soil intake hole blocking body 13 enters the groove 72a by pushing the rod 5 and pushing the outer tube 11 in the soil intake hole fully closed state, Since the soil intake hole blocking body 13 does not rotate in the circumferential direction of the outer tube 11, the soil sampling tube device 1 is locked in the soil intake hole fully closed state. Therefore, it is possible to prevent the soil intake hole 18 from being opened during the movement of the soil sampling tube device 1.

尚、図12に想像線で示したように、対向縁76;76aを、延長縁75;75aに対して傾斜する傾斜縁(底縁77;77aから開口部16の中心側に向かうような傾斜縁)に形成すれば、溝72;72aに対する土壌取込孔塞体13の出入が容易となり、溝72;72aと土壌取込孔塞体13とによるロック動作及びロック解除動作の確実性が高まる。   In addition, as shown by the imaginary line in FIG. 12, the opposing edge 76; 76a is inclined with respect to the extended edge 75; 75a (inclination toward the center side of the opening 16 from the bottom edge 77; 77a). If it forms in an edge | side, the entrance / exit of the soil intake hole obstruction | occlusion body 13 with respect to the groove | channel 72; 72a becomes easy, and the reliability of the lock operation | movement by the groove | channel 72; 72a and the soil intake hole obstruction | occlusion body 13 and unlocking | release operation increases. .

尚、実施形態5の土壌採取管装置1に、上述した水密性能維持部60、分割可能な内管12、後述するスリット付き土壌取込孔塞体13、傾斜面付き土壌取込孔塞体13、スリット及び傾斜面付き土壌取込孔塞体13のうちの1つ以上の構成を加味した土壌採取管装置1としてもよい。   In addition, the water sampling performance maintenance part 60 mentioned above, the inner pipe | tube 12 which can be divided | segmented, the soil intake hole obstruction body 13 with a slit mentioned later, and the soil intake hole obstruction body 13 with an inclined surface are added to the soil sampling tube apparatus 1 of Embodiment 5. Moreover, it is good also as the soil sampling tube apparatus 1 which considered one or more structures of the soil intake hole obstruction | occlusion body 13 with a slit and an inclined surface.

実施形態6
実施形態6の土壌採取管装置1は、前提構成の土壌採取管装置1に、図14に示すような、土壌取込孔塞体13の突出方向の先端縁13tから内管12の方向に向けて延長する切欠部により形成された複数のスリット(溝)23;23…を有し、この複数のスリット23;23…が土壌取込孔塞体13の突出長さの半分以上の長さに形成された土壌取込孔塞体13を備えた構成とした。
このスリット23は、図2(a)のように土壌取込孔塞体13の一方の板面13aが開口部16の長辺縁16aに接触して土壌取込孔18が全開放された土壌取込孔全開状態から当該土壌取込孔全開放状態を維持する方向(一方方向A)に外管を回転させる場合や、図2(b)のように土壌取込孔塞体13の他方の板面13bが開口部16の長辺縁16bに接触して土壌取込孔18が閉塞された土壌取込孔全閉状態から当該土壌取込孔全閉状態を維持する方向(他方方向B)に外管11を回転させる場合に、土壌取込孔塞体13が受ける土抵抗を低減させる構成となるので、外管11を回転させて土壌取込孔18を開閉する際において、土壌取込孔塞体13の受ける土抵抗が低減するため、外管11の回転負荷を軽減できるようになる。
Embodiment 6
The soil sampling tube device 1 of the sixth embodiment is directed to the soil sampling tube device 1 of the prerequisite structure from the leading edge 13t in the protruding direction of the soil intake hole closing body 13 toward the inner tube 12 as shown in FIG.

It was set as the structure provided with the formed soil intake hole obstruction | occlusion body 13. FIG.
As shown in FIG. 2A, the slit 23 is a soil in which one plate surface 13 a of the soil intake hole blocking body 13 contacts the long edge 16 a of the opening 16 and the soil intake hole 18 is fully opened. When rotating the outer tube in the direction (one direction A) for maintaining the fully open state of the soil intake hole from the fully open state of the intake hole, or the other side of the soil intake hole blocking body 13 as shown in FIG. The direction (the other direction B) which maintains the said soil intake hole fully closed state from the soil intake hole fully closed state where the board surface 13b contacted the long edge 16b of the opening part 16, and the soil intake hole 18 was obstruct | occluded When the outer tube 11 is rotated, the soil resistance received by the soil intake hole blocking body 13 is reduced. Therefore, when the outer tube 11 is rotated to open and close the soil intake hole 18, the soil uptake is performed. Since the earth resistance received by the hole closing body 13 is reduced, the rotational load on the outer tube 11 can be reduced.

土壌取込孔塞体13の辺縁21aから辺縁22aの方向に延長する切欠部により形成されたスリット23や、土壌取込孔塞体13の辺縁22aから辺縁21aの方向に延長する切欠部により形成されたスリット23を設けてもよい。そして、スリット23を形成する切欠部は、長さが、土壌取込孔塞体13の板面に切欠部の延長方向に沿って引いた線の長さの1/2以上であればよい。即ち、このような切欠部によるスリット23が形成された土壌取込孔塞体13を有した土壌採取管装置1とすれば、外管11の回転負荷をより軽減できるので好ましいが、スリット23を形成する切欠部の長さは、上述した1/2以上でなくてもよい。1/2以上でなくても、スリット23を備えるだけで、外管11の回転負荷をより軽減できるからである。   A slit 23 formed by a notch extending from the edge 21a of the soil intake hole closing body 13 to the edge 22a, or an extension from the edge 22a of the soil intake hole closing body 13 to the edge 21a. You may provide the slit 23 formed of the notch part. And the notch part which forms the slit 23 should just be 1/2 or more of the length of the line | wire drawn along the extension direction of a notch part in the plate | board surface of the soil intake hole obstruction | occlusion body 13 in length. That is, it is preferable to use the soil sampling tube device 1 having the soil intake hole blocking body 13 in which the slits 23 formed by such notches are formed, because the rotational load of the outer tube 11 can be further reduced. The length of the notch to be formed need not be 1/2 or more as described above. This is because the rotational load of the outer tube 11 can be further reduced only by providing the slit 23 even if it is not ½ or more.

尚、実施形態6の土壌採取管装置1に、上述した水密性能維持部60、分割可能な内管12、ロック部70、後述する傾斜面付き土壌取込孔塞体13のうちの1つ以上の構成を加味した土壌採取管装置1としてもよい。   In addition, one or more of the watertight performance maintaining unit 60, the splittable inner tube 12, the lock unit 70, and the soil intake hole blocking body 13 with an inclined surface described later are added to the soil sampling tube device 1 of the sixth embodiment. It is good also as the soil sampling tube apparatus 1 which considered the structure of these.

実施形態7
実施形態7の土壌採取管装置1は、前提構成の土壌採取管装置1に、図15に示すような、土壌取込孔塞体13の突出方向の先端縁13t側における開口部16の長辺縁16aに接触する一方の板面13a側が、他方の板面13bから一方の板面13aの中央に向けて傾斜する傾斜面20aに形成された土壌取込孔塞体13を備えた構成とした。
この傾斜面20aは、図2(b)のように土壌取込孔塞体13の他方の板面13bが開口部16の長辺縁16bに接触した土壌取込孔全閉状態から当該土壌取込孔全閉状態を維持する方向(他方方向B)に外管11を回転させる場合に、土壌取込孔塞体13が受ける土抵抗を増加させる構成であり、これにより土壌取込孔塞体13の他方の板面13bと開口部16の長辺縁16bとの接触力が大きくなるので、土壌取込孔塞体13の他方の板面13bと開口部16の長辺縁16bとの間を介して、土壌採取目標位置50以外の地中の土壌を内管12内に取り込んでしまったり、土壌採取目標位置50において内管12内に取り込んだ汚染土壌を土壌採取目標位置50以外の地中に撒き散らして汚染を拡大させてしまうようなことを防止できる。
Embodiment 7

One plate surface 13a side in contact with the edge 16a includes a soil intake hole blocking body 13 formed on an inclined surface 20a inclined from the other plate surface 13b toward the center of the one plate surface 13a. .
As shown in FIG. 2 (b), the inclined surface 20 a is formed from the soil intake hole fully closed state in which the other plate surface 13 b of the soil intake hole closing body 13 is in contact with the long edge 16 b of the opening 16. When the outer tube 11 is rotated in a direction (the other direction B) for maintaining the closed hole fully closed state, the soil resistance received by the soil intake hole blocking body 13 is increased. Since the contact force between the other plate surface 13b of 13 and the long side edge 16b of the opening portion 16 is increased, the distance between the other plate surface 13b of the soil intake hole closing body 13 and the long side edge 16b of the opening portion 16 is increased.

Thereby, since the rotational force of the direction which closes the soil intake hole 18 is added to the soil intake hole obstruction | occlusion body 13, when the soil sampling pipe apparatus 1 moves in the ground, the soil intake hole fully-closed state is maintained. Therefore, it is possible to prevent the soil intake hole 18 from being opened during the movement of the soil sampling tube device 1. Therefore, soil in the ground other than the soil collection target position 50 is taken into the inner pipe 12, or contaminated soil taken into the inner pipe 12 at the soil collection target position 50 is put into the ground other than the soil collection target position 50. It is possible to prevent spreading and spreading the contamination.

傾斜面20aは、土壌取込孔塞体13の辺縁21aや辺縁22aに設けてもよい。
