The following points should be paid attention to when applying the anchor cable and cast-in-place pile technology of soil anchor drilling rig

1) Prestressed coating anchor cable has high requirements for construction technology and quality. Therefore, before construction, it is necessary to prepare reasonable construction organization scheme, select high-quality construction team, strengthen construction management, and strictly control each process.

2) During the anchor cable construction of prestressed anchor drilling rig, attention should be paid to recording the bottom layer exposed in the drilling process. If there is obvious difference between the stratum and the exploration report, it should be reported to the relevant departments for timely correction.

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

4) In the process of construction, the deformation of foundation pit and the change of anchor cable internal force must be closely monitored, the dynamic tracking observation must be carried out, the information feedback method must be used to guide the construction, and the design parameters must be adjusted in time to obtain the best effect.
