Several points should be paid attention to when applying cable anchor and cast-in-place pile technology of soil layer anchor drilling machine:

1) prestressed coated cable anchor has high requirements on construction technology and quality. Therefore, before construction, a reasonable construction organization plan should be prepared, one of which is to select high-quality construction teams and strengthen construction management, strictly control each process.

2) in the construction process of prestressed anchor cable of anchor drilling machine, attention should be paid to record the underlying situation exposed during the drilling process, and when it is found that there are obvious differences between the formation and the address Exploration Report, it should be reported to relevant departments for timely correction.

3) cable anchor cable is tensioned and locked, there will inevitably be a certain degree of internal force attenuation. It is necessary to analyze the reasons according to the actual situation and adjust the construction technology or design parameters accordingly.

4) during the construction process, the deformation of foundation pit and the change of internal force of anchor cable must be closely monitored, dynamic tracking and observation should be carried out, the construction should be guided by information feedback method, and the design parameters should be adjusted timely to obtain the best effect.
