DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

      The term "packer" as used herein means a construct for sealing the perforation hole in the form of an air tube, rubber stopper or impermeable bag packer for pressurized grouting in the perforation hole, The invention is based on a packer made of semi-permeable cloth and adapted to the length and diameter of the packer according to the softness of the surrounding ground of the packer.

"Component member" means a nail or anchor to be inserted into a perforation hole, a bag packer injection hose, a grouting injection hose, a discharge hose, a cement milk injection hose or the like.

Packing Packer Injection hose can use various materials, but it is preferable to use PE hose.

The "discharge hose" is used when discharging air from the perforated hole and discharging the ground water. When the grout liquid comes out, cut off the hose or block the valve.

"Nail" means that reinforcing bars, pipes, wires, etc. are grouted over the entire length in the perforation hole, and "anchor" means a portion where reinforcing bars, pipes, Means a member having a portion which is covered with a tensile material and which is free from a loud sound volume even in a grooved perforation hole.

"Filter material" means a member configured to allow only cement milk and quick-setting water to escape and to allow water to escape therefrom. Examples thereof include sponge and nonwoven fabric. The filter material is wound around the constituent member to bind the bag to the outside and to bind the bundle to the bundling line, thereby preventing the cement milk and quick-setting agent from escaping even if the constituent members overlap.

It is preferable to use a semi-permeable fabric made of high strength fiber as the "bag of Packer Packer". The turret is preferably resilient in the perforation hole.

"Paper tape" is intended to make it easier to insert into a perforation hole by making the diameter of the paper tape wrapped around the outside of the bag packer filled with powder, When cement milk is injected, it stands up to a certain pressure, and if it is higher than a certain pressure, the tape can be peeled off or cut.

"Quick-filling" is a formulation which is mixed with cement milk and rapidly solidified, and powder-type rapid dispenser is used, which is introduced into the bag packer and sealed at both ends of the packer by binding wires. The quick-setting agent reacts with the cement milk injected through the shell packer injection hose 12 to form a cement bonded body. The cement milk preferably has a water cement ratio of 45% to 48%. The amount of the quick-setting agent used is between 3% and 20% of the volume of the packer, and the quality of the quick-setting agent is suitable for use in the case of a powder type quick-setting agent developed for shotcrete or anchor grouting.

The purpose of the present invention will be described in comparison with the prior art. In the prior art, the plastic bag packer used in the prior art was cured by injecting cement milk or mortar mixed with a rapid setting agent. However, it takes much time to cure, And thus it failed to fulfill the role of Packer.

On the other hand, the air packer can be easily expanded and contracted, but it has a disadvantage in that it is difficult to pack because of the limit of the expansion diameter in the soft ground. Further, when a plurality of injection hoses and nails or steel rods are inserted together in the perforation holes, the sealing performance is insufficient and the pressurized grouting can not be practically performed. The reason for this is that it is difficult to carry out perfect packing because many component members are inserted into the perforation holes. Therefore, the present invention aims to solve the above problems.

       It is a principal object of the present invention to provide a bag packaging machine capable of withstanding high pressure even when various components are inserted in the perforation hole.

BRIEF DESCRIPTION OF THE DRAWINGS Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The construction method of the bag packer will be described in the order of Figs. 5 to 11. Fig.

Fig. 5 shows a step of winding the filter material 14 at the position where the nail 11 and the plurality of hoses are fastened with the bag.

It is preferable that the filter material 14 can be taped by applying an adhesive to one side thereof. The filter material to which the adhesive is not applied can be wound and fixed with a wire or the like. The filter material 14 is preferably made of a material capable of filtering the suspension in which cement milk and quick-setting admixture are mixed. The filter material 14 is preferably a sponge or a nonwoven fabric. The filter material 14 may be wrapped around nails and various hoses and then both ends may be bundled with a wire or fixed with a cable tie or the like. The filter material 14 is a member configured to prevent the solid component of cement milk and quick-setting agent from escaping and to allow only water to escape. Here, the term "exiting only water" means water containing a slight suspension of cement milk and quick-setting suspension, except for the solid component. The filter material 14 is made of a material such as a sponge or a nonwoven fabric. The distance between the left and right filter materials is equal to the length of the packer, and the length of the packer is adjusted according to the softness of the surrounding ground of the packer.

On the left side of the drawing, the turret 16 is fixed with a binding wire 15 on the filter material 14 wound around the nail 11 and the plurality of hoses, and the turret 16 is turned upside down. At this time, it is preferable to use wire as the binding wire 15, but cable ties or hose clamps may be used. As described above, when the bag 16 is bundled and turned upside down, the cement milk is inflated and expanded later, thereby making it possible to improve the close contact with the perforation hole. However, the left side of the turret 16 may be tied to the outside as shown in the step of Fig. The bag 16 is preferably semi-permeable so that cement milk and quick-setting can not escape and only water can escape. The cement milk used herein preferably has a water to cement ratio of 45 to 48%. The bag 16 may be a circular surface made without a knot or a barrel sewn. The diameter of the bag 16 should be larger than the diameter of the perforation hole, and in soft soil, a harder soil material having a larger diameter is used.

Fig. 7 is a view showing the step of filling the powdered acetic acid settling vessel 17 inside the inverted bag 16.

It is preferable that the quick-setting agent 17 injected into the bag 16 satisfies the content of about 3% to 20% of the volume of the bag 16. The amount of the quick-setting agent 17 can be increased or decreased according to the design of the required condensation time. The powder type quick-setting admixture 17 is easily mixed and reacted with the cement milk injected through the shell packer inlet hose 12 after the production of the bag packer, and thus forms a cement bonded body. The setting time of the quick-setting admixture can be adjusted by adjusting the amount of the rapid setting admixture according to need, and the setting time through the blending test is designed.

The paper tape 18 is bound circularly or spirally such that the diameter of the bag packer becomes smaller on the outside of the bag 16 filled with about 3% to 20% of the powdery quick-setting material 17. By binding the bag 16 with the paper tape 18, the quick-setting agent is prevented from being disturbed in the bag and facilitated to be inserted into the perforation hole. When the paper tape 18 is spirally bound, insertion into the perforation hole is facilitated. It is preferable that the paper tape 18 has a strength enough to easily break or peel off when the bag 16 is inflated.

Fig. 10 shows the step of inserting the nail 11 or the anchor to which the packer is coupled in the perforation hole 20. Fig.

The nail 11 or the anchor is inserted into the perforation hole so that the bag packer is inserted up to the position where the bag 16 is to be positioned. At this time, the bag packer is preferably manufactured to have a diameter to be inserted with a slight clearance in the perforation hole.

11 is a view showing a step in which a bag packer is expanded in a puncture hole when a cement milk is injected into an injection hose in a packer to function as a packer.

When cement milk is injected into the bag packaging machine infusion hose 12 in the packer, the cement milk and the quick-setting dispenser 17 are mixed, and the paper tape 18 wound around the bag 16 is cut off by the injection pressure, 20, the bag 16 is inflated to function as a packer.

At this time, only cement milk and quick-setting water are prevented from escaping from the filter material 14 and the semi-permeable bag 16, and only the water is allowed to escape. When the quick-setting material rapidly condenses and the bag is tightly adhered to the outer peripheral surface of the perforation hole And acts as a packer.
