Abstract

The present invention relates to a corrugated pipe type earth anchor and a construction method thereof. While strands coupled to a bearing body are accommodated in a hollow corrugated pipe, a filler is leaked to the outside of the corrugated pipe through a first leakage unit firstly opened by the pressure of the filler, such as cement paste, injected into and filled in the corrugated pipe to expand a packer of a boring hole in which the corrugated pipe type earth anchor is constructed. After a gap between an anchoring length and a free length of the boring hole is sealed, a protective tape is removed by the pressure of the filler, and then the filler is leaked to the outside through a second leakage unit opened next to the first leakage unit such that an opening or a sink hole formed around the anchoring length of the boring hole and the anchoring length are densely filled. According to the present invention, when the corrugated pipe type earth anchor is fixed to the boring hole of the ground, the opening or the sink hole formed around the anchoring length is densely filled such that the corrugated pipe type earth anchor can improve a frictional force of a foundation ground and the cement paste or the filler in the boring hole of the ground while the ground around the anchoring length of the boring hole is improved.

For example, the filler injection hose 300 is connected in a state fitted to a central through-hole (unsigned) of the pressure stopper 140.

The corrugated earth anchor 100 according to the present invention configured as described above is constructed by the corrugated earth anchor construction method (S100) according to the present invention shown in FIG. 2.

Corrugated earth anchor construction method (S100) according to the present invention is to insert and fix the corrugated earth anchor 100 according to the present invention in a perforated hole 100a that is inclined at an angle of approximately 30 to 40 degrees.

Referring to FIG. 2, first, the corrugated earth anchor 100 according to the present invention configured as described above is brought into the perforation hole 100a in which cement paste grouting is completed by its own weight (S110).

In the S110 process, it is preferable to form the perforated hole 100a in which the cement paste grouting is completed as shown in FIG. 3.

3 is a process diagram for explaining a process of forming a perforated hole 100a in which cement paste grouting is completed in order to construct a corrugated earth anchor 100 according to the present invention.

First, as shown in Figure 3 (a), as shown by arrows while spraying through the injection nozzle 411 coupled to the tip of the rod 410 installed inside the casing 400, the punctured water supplied from the high pressure pump bar Likewise, by drilling the perforated water into the space between the inner wall of the casing 400 and the rod 410, a perforation hole 100a for perforating the corrugated earth anchor 100 on the ground is drilled.

As shown in (a) of FIG. 3, when the perforated water is discharged into the space between the inner wall of the casing 400 and the rod 410 while drilling the perforated hole 100a, ground disturbance around the perforated hole 100a is minimized. It is possible to increase the friction between the filler and the base layer within the perforated hole 100a by minimizing ground disturbance.

In addition, when ground disturbances around the perforation hole 100a occur while perforating the perforation hole 100a with the perforation channel, the settlement of the perforation hole 100a through the casing 400 while rotating the casing 400. Inserting gravel and sand into the part can improve the frictional force of the settlement by improving the disturbed ground to maximize the tensile force of the earth anchor.

 Next, as shown in (b) of FIG. 3, after the perforation hole 100a is completed, the perforation hole 100a is injected by spraying a cement paste 400a instead of the perforated water through the spray nozzle 411. The rod 410 is pulled out while forming a blocking film to prevent the leakage of the pressured water from the surrounding ground to complete grouting of the cement paste in the perforation hole 100a.

Subsequently, as shown in Fig. 3 (c), the corrugated earth anchor 100 according to the present invention is rooted in the perforated hole 100a where the cement paste grouting is completed by its own weight. At this time, since the buoyancy occurs when the hollow corrugated pipe 120 inside the corrugated earth anchor 100 is empty, the hollow corrugated pipe 120 is used to minimize buoyancy and increase the self-weight of the corrugated earth anchor 100. ) It is preferable to insert the filler injection hose 300 inside and to fill the corrugated earth anchor 100 while filling the appropriate amount of the filler 200 so that the protective tape 123 is not separated.

After the corrugated earth anchor 100 according to the present invention is inserted into the perforated hole 100a where the cement paste grouting is completed by self-weight, as shown in FIG. 3 (d), the second process (S120) ) Before performing the casing 400 is removed.

As shown in (d) of FIG. 3, the corrugated earth anchor 100 according to the present invention is inserted into the perforated hole 100a in which the casing 400 is removed and the cement paste grouting is completed, and then the perforation is performed. The corrugated pipe 120 through the filler injection hose 300 connected to the pressure cap 140 coupled to the corrugated pipe 120 of the corrugated earth anchor 100 through the order packer 141 installed in the opening of the hole 100a ) The filler 200 is pressurized and injected first to expand the packer 130 attached to cover the first leaking portion 121 of the corrugated pipe 120 first, so that the corrugated earth anchor 100 is constructed. The space between the settlement and the free field of the perforation hole 100a is sealed (S120).

At this time, the order packer 141 is the cement paste 400 inside the perforation hole 100a while pressure-injecting the filler 200 into the corrugated pipe 120 by blocking the opening of the perforation hole 100a. Prevents leakage to the outside.

As such, by sealing between the anchorage and the free field of the perforation hole 100a, it is possible to prevent the settlement of the inner wall between the anchorage and the free field of the perforation hole 100a, and in particular, of both ends of the packer 130 The metal mesh 132 installed at the end facing the maguricap 110a prevents slippage and increases friction when the packer 130 expands between the anchorage and free field of the perforation hole 100a.

In addition, in the second process (S120), the filling pressure of the filling material 200 and the filling pressure of the filling material 200 are checked by a flow meter (not shown) connected to the filling material injection hose 300, and the primary pressure changes during the filling process of the filling material 200 When is detected, the filling material 200 is leaked to the outside of the corrugated pipe 120 through the first leaking part 121, and after the primary pressure change is sensed, when the secondary pressure change is sensed, the packer 130 is expanded. By detecting that it is completed, the injection amount of the filler 200 in the third process (S130) and the pressure of the filler 200 can be adjusted.

In the state in which the packer 130 is expanded and completely closed between the anchorage and the free field of the perforation hole 100a, finally, the filler 200 is introduced into the corrugated pipe 120 through the filler injection hose 300. ) Is additionally injected to release the protective tape 123 that is adhered to cover the second leaking portion 122 of the corrugated pipe 120 secondly, so that the corrugated earth anchor 100 is constructed. The pores or sinkholes formed around the settlement and the settlement are tightly filled (S130).

In addition, in the third process (S130), the filler 200 is checked with the above-described flowmeter and the pressure of the filler 200 is pressurized, and the packer 130 has been expanded as a result of pressure change detection during the pressure of the filler 200. When this is sensed, the protective tape 123 is detected from the second leaking part 122 of the corrugated pipe 120 from this time, and the filler 200 is adjusted by adjusting the injection amount of the filler 200 and the pressure of the filler 200. By additionally injecting, the anchorage of the perforated hole 100a in which the corrugated earth anchor 100 is constructed and the voids or sinkholes formed around the anchorage are tightly filled.

At this time, not only the pores or sink holes formed around the settlement during the drilling operation, but also the pores or sink holes already existing around the settlement are filled with the filling material 200 tightly.

In addition, in the third process (S130), the filling amount 200 and the filling pressure of the filling material 200 are checked by the flowmeter described above, and when the filling material 200 pressure is constantly detected during the filling 200 pressure injection, the corrugated earth The anchor 100 detects that the anchorage of the perforation hole 100a to be constructed and the voids or sinkholes formed around the anchorage are completely filled, and stops the pressure injection of the filler 200.

Thereafter, after curing the filler 200 and the cement paste 400a, when the tensile force is introduced into the corrugated earth anchor 100 according to the present invention described above and fixed to the ground hole 100a, the corresponding hole ( As the voids or sinkholes formed around the anchorage of 100a) are tightly filled, the frictional force between the filler and the ground within the perforation hole 100a of the ground is improved while the ground around the anchorage of the perforation hole 100a is improved. This will increase.
