Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of slope anchor rod, concretely is a slope anchor rod that effectively avoids oxidation corrosion. BACKGROUND

[0002] The slope refers to the slope surface with a certain gradient made on both sides of the roadbed to ensure the stability of the roadbed. The slope widely exists in the mountain, hilly and urban construction, and is an important part of the geological structure and landform. In modern engineering construction, anchor rod support is used as a reinforcing support in slope, rock-soil, deep foundation pit and other landmark engineering, tunnel and other underground chamber construction. After the anchor rod is stressed, a compression zone is formed within a certain range. By appropriately arranging the anchor rods, the compression zones formed by adjacent anchor rods overlap each other to form a compression zone, thereby enhancing the integrity and bearing capacity of the stratum.

[0003] A capsule bag type anchor rod is disclosed in Chinese Utility Model Patent No. CN217536939U, which includes an anchor rod body and a capsule bag. The anchor rod body is inserted into the capsule bag. A pressure plate is arranged at the upper end of the capsule bag at the position where the anchor rod body penetrates. An anchor guide head is arranged at the lower end of the capsule bag. A first grouting pipe is arranged on the pressure plate and extends to the bottom of the capsule bag to perform a first in-bag grouting. A first grouting pipe extension is also arranged at the upper end of the capsule bag. The inlet of the first grouting pipe extension is connected to the overflow outlet of the first grouting pipe, and the lower end of the first grouting pipe extension penetrates through the anchor guide head to communicate with the first in-bag grouting. A second grouting pipe is arranged in the capsule bag and penetrates through the pressure plate, the capsule bag and the anchor guide head to directly discharge cement grout from the lower end of the anchor guide head to perform a second out-of-bag grouting. The capsule bag type anchor rod has strong pullout resistance, is easy to install, and has high grouting efficiency.
