Therefore, the PHC tubular pile bearing capacity design value is higher than that of the immersed tube cast-in-place pile, the bored pile and the manual hole digging pile with the same diameter.
2. The PHC pipe pile with wide application range is characterized in that the lateral resistance and the end resistance bear upper load together, and can select various soil properties such as strong weathered rock stratum, fully weathered rock stratum, hard clay layer or compact sand layer (or pebble layer) as a bearing layer, and the PHC pipe pile has strong adaptability to geological conditions with large fluctuation of the bearing layer, so that the PHC pipe pile is wide in application region and multiple in building types. The method is widely applied to various high-rise buildings below 60 layers, industrial and civil building low bearing platform pile foundations, engineering foundations such as railways, highways and bridges, ports, wharfs, water conservancy, municipal works, structures, large equipment and the like.

2. Theodolite observation
The method is characterized in that the front and the side are perpendicular to form 90 degrees, and the theodolite is used for observing, so that the measurement data are accurate, but two theodolites and more constructors are needed, and the cost is increased, and the time is consumed.
3. Perpendicularity adjustment of pile machine tower
