Manufacture method of prestressed reinforced concrete piles

Method for manufacturing prestressed concrete piles, comprising the steps of: using horizontal steel frame mold mounted by tensioning the tensioning appliance in front clamping plate, the end plate to the circumferential symmetry Tensioning reinforcement fpy 10% of the standard value, then the upper and lower after the mold halves is completed composition, symmetrical fastening bolt, and again used in the appliance tensioned tensioning plate, the circumference of the end plates symmetrically to the tension reinforcement of 105% fptk for 2min load back to 100% fpy will lock anchor immediately after 10-20min checksum, after passing the mold fill sheets lifted straight into a fixed vertical shaft kiln, a hopper mounted concrete pouring concrete from the upper end of the rear plate center hole fill tensile stress, and the vibrators insert core concrete pile , starting from the bottom of the pile vibration, the vibrator and gradually pulling out, until all the vibration compacting concrete pile core; pile pouring closure is completed through heat curing kiln, vertical kiln balanced temperature kept at 60-80 ℃, through continued heat for at least 24 hours and then lifted out of the kiln for the mold release sheet, and removal of the template, cut pile tip exposed reinforcement, and maintenance of at least 5 days at room temperature.
