This type of pile has the characteristics of small piles, large quantity and high construction precision requirements. During the construction process, a large number of personnel are often required to ensure construction precision, and the construction efficiency is not high, making it difficult for the construction organization to achieve flow operations.

[0003] Microporous cast-in-place piles in photovoltaic projects are usually required to be arranged in a matrix of horizontal rows and vertical columns, with the horizontal rows and columns perpendicular to each other, and the deviation of the formed pile position is less than 2CM, and the vertical deviation is less than 2 degrees. The previous construction method of microporous cast-in-place piles is: the construction personnel will straighten the expected pouring pile positions of each group, and then put the steel cage into each pouring hole respectively, measure the distance between it and the front pile and the rear pile by tape measure, determine the longitudinal and lateral position of the pile position, and the surveyor will fix it by hand and pour it. This construction method requires construction personnel to measure the construction position of each microporous cast-in-place pile with a ruler, and after the measurement is accurate, personnel must fix it by hand. This construction method is inefficient, it is difficult to form a flow operation, and it causes a lot of waste of manpower, which is not conducive to the stability control of the construction quality of microporous cast-in-place piles.
