Description
Technical Field

Background
The anchoring technology is mainly applied to tension members in the geotechnical anchoring engineering, and a reliable anchoring device is formed by connecting steel bars and steel strands. The tension type anchor rod (cable) in the traditional engineering mainly relies on friction to provide tension, the improved technology is pressure type, and the extrusion force of soil layer constraint is increased besides the traditional friction force.

However, engineering practice shows that the full replacement of the cement soil slurry in the large-diameter expanded body anchoring section is difficult to realize by adopting a pressure grouting method, and in actual engineering, the compressive strength measured value of the cement soil sampling is far lower than 20MPa; (2) The controllability of construction quality is poor, the rotary spraying construction is easily influenced by human factors, and the level and responsibility of an operator and the performance and state of a high-pressure pump system directly influence the anchorage quality of the expansion anchor rod; (3) The problems of corrosion resistance and durability are solved, and the construction of the rotary spraying expanded body anchoring section is difficult to realize the 30MPa compressive strength required by the standard, so that the pressure type expanded body anchoring technology is difficult to adopt. The anchoring body of the tensile expanded anchor rod is extremely easy to crack after being pulled, so that the problem of corrosion of the expanded anchor rod is caused, and the durability is reduced, so that the problem of long-term safety of an anchoring system is possibly caused; (4) The problem of the anchor rod tendon body placement can not guarantee centering, when the expansion anchor rod is constructed by adopting a jet grouting reaming technology, the phenomenon that the anchor rod body is in a deflection layout often occurs in an expansion anchoring section, particularly in an inclined expansion anchoring project, and therefore, a pressure-bearing type bag-type expansion head anchoring device is needed to solve the problem.
