置がずれているといつた場合がしばしば生じる。
This method ranges from simple hand-held equipment to equipment equipped with a pressurizing device, and single augers are connected one after another to drill a long extension. However, as the distance increases, directionality deteriorates and the hole becomes larger at the exit. This often occurs when the position is said to have shifted.

これはオーガーを順次接続した場合のジヨイン
ト部のガタやオーガーの自重が作用するためであ

This is due to play in the joint and the weight of the auger when the augers are connected one after another.

Next, an embodiment will be described in which the drilling device of the present invention is comprised of a manual guide rod and a mechanically driven hollow auger.

<1> 手動案内ロツド 手動の案内ロツドは先端ロツド1と延長用ロ

<1> Manual guide rod The manual guide rod consists of a tip rod 1 and an extension rod 2.

先端ロツド1はロツド11の先端にオーガー

The tip rod 1 has an auger 12 provided at the tip of a rod 11, and a joint portion 13 formed at the rear end.

一方延長用ロツド2は単に両端に継手部21

On the other hand, the extension rod 2 simply has joints 21 at both ends.
It is a rod-shaped body.

If the cross section is circular, flat parts 14 and 22 are formed at appropriate intervals so that both the tip rod 1 and the extension rod 2 can be rotated by the manual handle 3.
4 and 22 are engaged with square holes or jaw-shaped openings formed in the manual handle 3 to rotate the rod.

For example, the joint parts 12 and 21 of the rods 1 and 2 are formed with symmetrical notches as shown in the figure.
It is possible to adopt a configuration in which once inserted from the side, it does not slip out in a direction perpendicular to the insertion direction.

With this structure, the rods 1 and 2 will slide out in the insertion direction, but as will be described later, since the rods 1 and 2 are inserted into the hollow auger 4, they will not come out of engagement and rotational force and axial force can be transmitted.

<2> Mechanically driven auger The mechanically driven hollow auger 4 has spiral blades 42 attached to the outer periphery of a hollow cylinder 41 and has a shape with both ends open, and the internal hole diameter is at least larger than the outer diameter of the rods 1 and 2. The structure is such that the rods 1 and 2 can freely rotate and slide within a large hollow cylinder 41.

そして中空筒41両端には継手部を有し順次

Further, the hollow auger 4 is attached to and detachable from the drive section 5, and the strong rotational force of the drive section 5 allows the auger 4 to be press-fitted into the ground to remove soil.

駆動部5には保持用のハンドル51や回転方

The drive part 5 has a through hole in the center, and the inner diameter of this through hole is larger than the outer diameter of the rods 1 and 2, and when the rods 1 and 2 are inserted, they can rotate and slide inside.

次に操作方法について説明する。 Next, the operating method will be explained.

<1> 案内ロツドの進入(第1図) まず立坑内、その他の壁面から地山中に水平
方向、斜方向に案内ロツド1を圧入する。
<1> Insertion of the guide rod (Fig. 1) First, the guide rod 1 is press-fitted horizontally and obliquely into the ground from other walls in the shaft.

この圧入操作は手動ハンドル3を入力により
回転して行う。
This press-fitting operation is performed by rotating the manual handle 3 by input.

先端ロツド1の先端オーガー12は木ねじを

The tip auger 12 of the tip rod 1 is press-fitted into the ground like screwing in a wood screw.

先端ロツド1がほとんど地山中に圧入された

When the tip rod 1 is almost press-fitted into the ground, connect the extension rod 2.

<2> Setting the hollow auger (Fig. 2) Remove the manual handle 3 from the extension rod 2 and insert the hollow auger 4 into the outer periphery of the rod. A driving part 5 is integrated with the base end of the hollow auger 4, and since the driving part 5 also has a through hole in the center, it can be inserted into the outer periphery of the extension rod 2 as it is.

<3> 中空オーガーの掘進(第3図) 駆動部5内のモーターの回転により、あるい

<3> Excavation of the hollow auger (Fig. 3) The hollow auger 4 is rotated by the rotation of the motor in the drive unit 5 or by input to the drive unit 5 from an external power source, and the earth is removed by applying axial force. Drill the hole while doing so.

このとき先行した案内ロツド1,2が掘進方
向を案内するから機械力による中空オーガー4

く不用でありそうした操作を考慮せずに迅速に
掘進できる。
At this time, the leading guide rods 1 and 2 guide the excavation direction, so the hollow auger 4 is operated by mechanical force.
There is no need to check or correct the direction when operating the tunnel, and digging can be carried out quickly without considering such operations.

なお中空オーガー4に軸方向力を与える方法
としては削孔する壁面に対向して設けた反力壁

As a method of applying axial force to the hollow auger 4, it is possible to use a hydraulic cylinder or the like which absorbs the reaction force on a reaction wall provided opposite to the wall surface to be drilled.

<4> Advancement of the guide rods (Fig. 4) The guide rods 1 and 2 are advanced again according to the length that the hollow auger 4 has dug. At this time, most of the rods 1 and 2 are located inside the hollow auger 4, so the resistance of the soil to manual rotation is the same as the resistance at the time of initial press-in and will not increase even if the excavation length is extended. .

更に手動回転によるゆるやかな圧入であるか
ら元来直進性が良いが例え方向に狂いが生じて

加えることにより容易に行うことができる。
Furthermore, since it is a gentle press-fit by manual rotation, the straightness is originally good, but even if a deviation occurs in the direction, it can be easily corrected by applying a biased force to the handle.

<5> 中空オーガーの接続、掘進(第5図) 次に中空オーガー4を接続し軸方向力を与え

<5> Connecting and digging the hollow auger (Fig. 5) Next, the hollow auger 4 is connected, and axial force is applied to dig by mechanical rotation. Because it is press-fitted into the ground, it does not fall due to its own weight or shift due to play in the auger connection.

本発明は上記したように手動回転により圧入す

のオーガーにより地中を削孔する装置である。
As described above, the present invention is an apparatus for drilling underground using a guide rod that is press-fitted by manual rotation and a mechanically driven auger that is fitted around the outer circumference of the guide rod.

従つて次のような効果を期待できる。 Therefore, the following effects can be expected.

<1> 正確に地中に圧入できる軽量の手動の案
内ロツドに沿つて機械力による削孔、圧入を行

<1> Since drilling and press-fitting are carried out by mechanical force along a lightweight manual guide rod that can be accurately pressed into the ground, accurate drilling is possible with almost no influence of downward movement due to the machine's own weight or eccentricity due to centrifugal force. It can be performed.
