The invention provides a construction method for pre-stress bamboo joint piles. The construction method includes (1) preparation work which includes measurement and positioning of put lines, in-position arrangement of a pile machine and acceptance checking and stacking of multiple pre-stress bamboo joint piles, (2) lifting, inserting and pressing of a lower joint pile of a first pre-stress bamboo joint pile, (3) lifting, mechanical pile splicing, pressing and delivering of an upper joint pile of the first pre-stress bamboo joint pile, (4) the pile machine transferring and repeating of steps (2)-(3) till construction of all pre-stress bamboo joint piles can be finished, and (5) operations that an upper joint pile of each pre-stress bamboo joint pile is mechanically connected with one anchor bar and all anchor bars are connected with cushion cap reinforcing steel bars. According to the construction method for the pre-stress bamboo joint piles, the upper joint piles are mechanically connected with the lower joint piles, the upper joint piles are mechanically connected with the anchor bars, working hours are saved, safety and reliability are achieved, costs are low, construction qualities of the pre-stress bamboo joint piles can be effectively guaranteed, and high-speed, safe and economical advantages are achieved.
