ている。2. Description of the Related Art Conventionally, in civil engineering or construction work,
For the purpose of enhancing the support force of the pile, a cloth bag is attached to the tip of the pile, and after the pile is embedded in the ground, a hardening material such as high-pressure concrete is press-fitted into the bag, and the hardening material concerned. There is known a method of inflating the bag body by pressing and fixing the bag body to the ground, which is described in, for example, Japanese Patent Publication No. 40491/1992.
【０００３】[0003]
【発明が解決しようとする課題】この方法は、杭を硬化
材料で膨まされた袋体を介して地盤に強固に固定する必
要があるため、硬化材料は袋体内に高圧で圧入され、袋
体はその高い圧力に耐えるものであることが必要であ
る。In this method, since the pile needs to be firmly fixed to the ground through the bag body expanded with the hardening material, the hardening material is press-fitted into the bag body at a high pressure, The body needs to withstand the high pressures.
【０００４】そしてその袋体の両端部は、強固に杭に固
定されていなければならず、袋体内に高い圧力が作用し
た場合においても、その固定部が破壊されたり、内部の
硬化材料が漏出することがあってはならない。Both ends of the bag body must be firmly fixed to the pile, and even when a high pressure is applied to the bag body, the fixing part is broken or the hardening material inside leaks out. There should be nothing to do.
【０００５】従来の杭においては、杭体より十分に大径

入することができなかったのである。In the conventional pile, the bag body having a diameter sufficiently larger than that of the pile body is squeezed at both ends and fastened with a metal band or the like to fix the pile body to the pile body. , When the high pressure acts on the bag, the bag expands,
Such a metal band was easily broken and the high-pressure hardened material could not be press-fitted.

３の縁を捲り上げるように作用する。FIG. 8 is a view showing a state in which the end portion of the bag body 2 is fastened and fixed to the pile body 1 with the metal band 3. When the pressure of the hardened material 4 press-fitted into the bag body 2 is low, the bag body 2 is properly tightened and fixed by the metal band 3 as shown by the solid line in FIG. When the body 2 is used and the pressure of the hardening material 4 becomes high, the bag 2
Expands due to the internal pressure, the end of the bag body 2 covers the outside of the metal band 3 as shown by the chain line, and acts to roll up the edge of the metal band 3.

バンド３内の圧力に耐え得るような強度を有していて
も、その一方の縁から捲り上げられるため、容易に破断
してしまうのである。また捲り上げられた金属バンド３
の縁により、袋体２が傷付けられる恐れもある。Therefore, even if the metal band 3 itself has a strength capable of withstanding the pressure in the metal band 3, it can be easily broken because it is rolled up from one of its edges. Also rolled up metal band 3
There is a possibility that the bag body 2 may be damaged by the edge of the bag.
【０００８】このように径の大きな袋体を使用する場合
には、硬化材料を高圧で注入することができないので、
地盤に対して強固に押付けることができず、杭の地盤へ
の固定強度を高めることが困難であった。When a bag having such a large diameter is used, the hardening material cannot be injected at a high pressure.
It could not be pressed firmly against the ground, and it was difficult to increase the strength of fixing the pile to the ground.
【０００９】本発明はかかる事情に鑑みなされたもので

固定せしめることを目的とするものである。The present invention has been made in view of the above circumstances, and it is possible to press a high-pressure hardening material into the bag body 2 without breaking the fixing tool, and to firmly fix the pile to the ground. That is the purpose.

The diameter of the bag body 2 is reduced by tightening 4 and 4, and the bag body 2 is firmly tightened and fixed to the surface of the pile body 1 at the small diameter portion 17.

る。4 is a pile 21 to which the bag body 2 is attached according to the present invention.
Fig. 4 (a) shows a state in which the
4 shows a state in which a pile burying hole 20 is drilled in the ground 19, and FIG.
(B) shows a state in which the pile 21 is inserted into the pile burying hole 20. The bag 2 in the pile 21 is in a deflated state, and the pile 2
1 can be easily inserted into the small-diameter pile burying hole 20.

The pile 21 is firmly fixed to the ground 19 by being strongly pressed against.

Here, when the curable material 4 is press-fitted into the bag body 2, the pressure of the curable material 4 causes the bag body 2 to expand as described above.

作用する。At this time, in the present invention, the rings 6 and 6 of the fixture 5 are made of steel rods and have high strength, and the bag 2
Since both ends of the bag are small-diameter parts 17 and the small-diameter part 17 is tightened by the fixture 5, the bag body 2 has a small effect of enlarging the diameter of the fixture 5 due to its internal pressure.
Is mainly exerted only by the force pushing the fixture 5 in the axial direction.
【００２３】そして固定具５は二本のリング６，６によ
って袋体２を締付けており、その接触面積が小さいた
め、袋体２内の硬化材料４の漏出を有効に抑止しつつ、
固定具５は袋体２の表面を滑ることができる。The fixture 5 has two rings 6 and 6 tightening the bag body 2 and the contact area thereof is small, so that the hardening material 4 in the bag body 2 can be effectively prevented from leaking out.
The fixture 5 can slide on the surface of the bag body 2.
【００２４】そのため袋体２が内圧で伸長すると、図５

る。Therefore, when the bag body 2 is stretched by the internal pressure,
As shown by the chain line, the fixing tool 5 slides and moves toward the end, so that the bag body 2 is allowed to expand and the force by which the bag body 2 expands the diameter of the fixing tool due to the internal pressure can be reduced.

However, by using the fixture 5 of the present invention, the action of moving the fixed part is generated along with the expansion of the bag body 2 due to the internal pressure, and the fixture 5 is not excessively expanded and broken. The bag body 2 is not damaged.

The small-diameter portion 17 of the bag body 2 is folded outward to form a double layer, and inside the folded edge 23, a flexible string, a rope,
An annular string-like object 24 such as a wire is interposed.
Then, the fastener 5 is tightened from the outside of the folded-back portion 25.

The bulged folded edge 23 is pressed, the terminal portion of the bag body 2 slides on the surface of the pile body 1, and the bag body 2 can be extended.

The bag 2 can extend and the inner ring 6
The ribs 26 prevent the fixture 5 from excessively moving.

害となることなく、杭２１を引抜くことができる。When this structure is applied to the fixture 5 at the upper end portion of the bag body 2 in FIG. 4, as described above, the bag body 2 is
Is permitted and excessive movement of the fixture 5 is prevented, and when it is necessary to remove the pile 21 due to inconvenience in burying the pile 21 in the pile burying hole 20, by removing the pile 21 As the bag body 2 moves in the distal direction with respect to the pile body 1, the fixture 5 also moves to the left in FIG. 7, and the outer ring 6 is caught by the ribs 26 to prevent further movement. Thus, the pile 21 can be pulled out without the bag body 2 excessively approaching the front end direction and becoming an obstacle.

強度が大きく、袋体２が膨むことにより一方から捲れ上
ったり、破断したりすることがない。According to the present invention, since the fixture 5 is composed of two rings 6 and 6, which are connected in parallel,
The strength is high, and the bag body 2 does not curl up from one side or break due to swelling.

５の径を拡大せしめる力を軽減することができる。Since the rings 6 and 6 tighten the bag body 2 linearly, the hardening material 4 is enclosed in the bag body 2 to prevent leakage thereof, and the contact area is small, so that the friction resistance is small. As the bag 5 extends due to internal pressure, the fixture 5 moves as the bag 5 slides between the fixture 5 and the bag body 2 or between the bag body 2 and the pile body 1, and the bag body 2 receives the internal pressure. Thus, the force for enlarging the diameter of the fixture 5 can be reduced.

できる。Further, the fixture 5 of the present invention comprises rings 6, 6
Both ends of the bag overlap each other, and the flanges 9 and 9 and the receiving flanges 10 and 10 are tightened at their ends by tightening means, so that the diameter is reduced. Can be tightened evenly.

If and are tightened by the tightening means, the rigidity of the rings 6 and 6 reduces the distance between the other flange 9 and the flange 10,
It can be easily tightened by tightening means such as the short bolt 13.

が小さいので、固定具５を拡げる力が生じない。Further, according to the method of the present invention, since the small-diameter portion 17 which substantially coincides with the outer diameter of the pile body 1 is formed at both ends of the bag body 2, wrinkles or the like will not be generated even when tightened by the fixture 5. Since the expansion due to the internal pressure is small in the small diameter portion 17, the force for expanding the fixture 5 does not occur.

Since the fixture 5 can move with it, both ends of the bag body 2 are fixed so that the bag body 2 can be fixed uniformly.
