Description of the Related Art The packer method is a general term for a method of sealing off the middle of a borehole wall in order to prevent backflow of chemicals when pressurized and injecting chemicals such as mortar into the ground, and a packer device is used. For example, in the ground anchor method, PC
A floating ring-shaped packer device is used, which is attached to the circumference of a cylindrical sheath that protects the steel from corrosion. Packer devices of this type are broadly classified into rubber and fiber pack devices from the viewpoint of materials; the former is generally used by injecting water or air, and the latter is used by injecting a caking agent such as cement milk under pressure.

。[Problems to be Solved by the Invention] The conventional packer method described above has the following problems. <A> Currently, when the peripheral surface of the sheath is formed in a continuous uneven shape, the adhesion between the packer device and the uneven surface of the sheath is poor. Therefore, as the injection pressure of the chemical liquid such as mortar that is pressurized into the anchor hole increases, the chemical liquid is more likely to leak from between the sheath and the peripheral surface of the packer device. <B> Since the packer device is inflated midway into the anchor hole, the sealing state of the packer device cannot be confirmed from the outside. <C> A hose for injecting fluids such as water and chemicals is connected to the packer device. Therefore, the smaller the hole diameter is, the more difficult it becomes to insert the packer device.

is an anchor hole drilled underground, 20 is a plurality of PC steel materials such as PC steel wire or PC steel stranded wire, 21 is a plurality of PC steel wires 20
It is a polyethylene sheath that covers the entire body and has continuous irregularities on its circumferential surface. 22 and 23 are PC steel materials 20
It is also an injection hose that is inserted into the sheath 21 and injects a chemical solution such as mortar into the inside and outside of the sheath 21. The structure of the above ground anchor is the same as the conventional one. The packer device according to the present invention includes a floating ring-shaped hollow bag 30 attached to the circumferential surface of the sheath 21 and a cylindrical water-blocking layer 31 interposed between the sheath 21 and the hollow bag 30. The hollow bag 30 is made of rubber or fiber, and a pressure hose for supplying various fluids is connected to a part of the bag. The water stop layer 31 itself does not have complete water stop properties, and is composed of, for example, urethane foam having countless micropores within its tissue. When the water stop layer 31 is manufactured by on-site foaming, the inner and outer surfaces of the water stop layer 31 are similar to the sheath 2.

Next, fluid is supplied to inflate the hollow bag 31. As a result, the outer periphery of the hollow bag 31 follows the irregularities of the ground and is crimped, and the inner periphery of the hollow bag 31 is reduced in diameter so as to be crimped to the outer periphery of the sheath 21 via the water stop layer 31. Next, the external consolidation material 40 is injected into the anchor hole 10 under pressure using the injection hose 23. The external consolidation material 40 increases the liquid level from the bottom of the anchor hole 10 and permeates into the water stop layer 31. Particles of the external consolidation material 40 form the water stop layer 31
When passing through the group of micropores in the water, the water becomes clogged and the water-stopping layer 31 is given a water-stopping function. Also, between the outer circumference of the water stop layer 31 and the circumference of the hollow bag 30, and between the inner circumference of the water stop layer 31 and the sheath 2
1 are in close contact with each other, and the water-stop layer 31 has water-stop properties, so there is no fear that the injection pressure of the external consolidation material 40 will leak to the outside, and the injection can be performed at high pressure.

A cylindrical water-stopping layer 32 made of rubber may be interposed between the circumferential surfaces of 0. In the case of this embodiment, the outer peripheral surface of the water stop layer 32 is covered with the sheath 21.
The uneven surface is formed in a shape that matches the uneven outer peripheral surface of. Alternatively, if the water stop layer 32 is made of soft rubber, the above-described uneven molding can be omitted. Further, the sealing property of the water stop layer 32 is provided by the expansion pressure of the hollow bag 30. Further, instead of the water stop layer 32 of the cylinder, a rod-shaped rubber material may be wound around and interposed between the sheath 21 and the hollow bag 30. It is necessary to form an uneven surface in a shape that matches the shape.
