The invention particularly relates to a construction method of a prestressed 
pipe pile with vertical 
water discharge grooves, and is used for solving the problems in the traditional construction of the prestressed 
pipe pile, such as 
sedimentation, bearing capability reduction and 
pollution to the construction field. The construction method comprises the following steps of a. uniformly distributing 
water discharge grooves on external circumference of the prestressed 
pipe pile, and arranging a V-shaped groove between two adjacent 
water discharge grooves, wherein the V-shaped groove is communicated with the two adjacent water 
discharge grooves; b. installing a water accumulation protection drum with an opening at the bottom at the 
insertion position of the prestressed pipe pile, wherein a water guide pipe communicated with the water accumulation protection drum is arranged on sidewall of the water accumulation protection drum and a control valve is arranged on the water guide pipe; c. inserting the prestressed pipe pile along the opening of the water accumulation protection drum, wherein pore water enters the water 
discharge grooves under the action of pressure, the pore water in the water 
discharge grooves rises and is discharged through the water guide pipe; and d. installing the water accumulation protection drum to the 
insertion position of next prestressed pipe pile. The construction method has reasonable and reliable structure design, not only can reduce 
insertion resistance to improve construction 
progress rate, but also has good effect of inhibiting 
sedimentation after construction, and has the advantages of simpleness in structure and easiness in implementation and control.
