The pile materials used as foundation pile engineering are in the market, such as tubular piles, various square piles, cast-in-place piles, drilled piles and the like. The pipe pile is cylindrical, and is rotated on a centrifuge at a high speed through a centrifugal pipe pile die, so that concrete in the pipe pile die performs high-speed centrifugal motion, and finally the concrete pipe pile with a circular hole in the center is manufactured.

However, at present, after the construction of the tubular pile is completed, the bearing capacity of the tubular pile needs to be detected, so that whether the tubular pile meets the use requirement is judged, a static load experiment is generally adopted when the bearing capacity of the tubular pile is detected, and a rapid load maintaining method is adopted by utilizing a counter-force device of a ballast platform. The load is applied to the pile top by the oil pump through the jack, and the resultant force center of the jack for applying the load controlled by the parallel connection of the jacks is coincided with the pile axis. The pile top settlement amount is measured by a displacement sensor, data are automatically acquired in the whole process by a static load testing instrument, and finally indoor data arrangement is carried out on the original data.

With respect to the related art in the above, the inventors consider that: thereby when carrying out the construction of tubular pile and consolidate the building in existing building, when detecting the tubular pile, need to carry the required test block of static load experiment etc. into the field to the hoist and mount of test block has reduced work efficiency.
