(One embodiment)
As shown in FIGS. 1 and 2, a ground anchor protection tube 10 according to an embodiment of the present invention is integrally formed of a transparent material, and includes a tube 12 and a side cap 24. The tube 12 has a small diameter portion 14 and a large diameter portion 16 connected to the small diameter portion 14. One end of the small diameter portion 14 of the tube 12 is connected to the side cap 24, and a storage space 18 is formed between the tube 12 and the side cap 24. The small diameter portion 14 has a perforation 20 near the side cap 24. The perforations 20 are radially connected to the storage space 18. The large diameter portion 16 has an opening 22 at one end. The opening 22 is coaxially connected to the storage space 18.

As shown in FIG. 3, when the ground anchor 50 is installed, one end of the large-diameter portion 16 of the pipe 12 of the ground anchor protection tube 10 abuts on the pressure receiving plate 30 made of concrete or synthetic steel. The pressure receiving plate 30 is in close contact with the wall surface of the retaining wall 56. When the tube 12 is covered by the anchor head 54 of the ground anchor 50, the anchor head 54 of the ground anchor 50 enters the storage space 18 from the opening 22 of the tube 12. Since the opening 22 of the tubular body 12 is sealed by the pressure receiving plate 30 that is in close contact with the retaining wall 56, the waterproof layer 32 flows into the storage space 18 from the perforation 20 and covers the anchor head 54 of the ground anchor 50 to provide a waterproof effect. Can occur. Finally, in order to protect the ground anchor 50, the metal sealing cap 34 may be put on the ground anchor protection tube 10 and the metal sealing cap 34 and the pressure receiving plate 30 may be fixed together by a plurality of bolts 36.
Due to the features of the above-described structure, the pressure receiving plate 30, the ground anchor protection tube 10, the waterproof layer 32, and the sealing cap 34 can constitute a ground anchor protection device 40 for stabilizing the ground anchor 50.

  Since the axial length L1 of the large diameter portion 16 of the tubular body 12 is equal to or less than の of the axial length L of the tubular body 12, the tubular body 12 and the sealing cap 34 may interfere with the assembly operation. Does not occur.

When the ground anchor protection tube 10 according to the present invention is not in an upright state (for example, is disposed horizontally or diagonally), the worker can easily inject the waterproof layer 32 into the storage space 18 through the perforation 20 due to the above-described structure. In addition, it is possible to prevent the waterproof layer 32 from flowing out of the storage space 18 through the side cap 24 during the injection process, and to fill the storage layer 18 with the waterproof layer 32. That is, the operation of injecting the waterproof layer 32 can be completed quickly and reliably without relying on another auxiliary tool, and the convenience of the installation operation can be improved.
After the installation work is completed, the ground anchor protection tube 10 is in a transparent state, and the waterproof layer 32 has a light-transmitting property. Therefore, the inspection worker visually judges whether or not the tendon 52 has been corroded or damaged. In addition, the inspection work can be done easily.
