s3, penetrating the steel strand to the lower ends of the front and rear lower beams of the bottom die, and fixing the bottom end of the steel strand to the lower plane of the section steel at the bottoms of the front and rear lower beams by using an anchorage device and an anchorage device clamping piece;
s4, processing a U-shaped clamp by using the round steel bar, enabling the U-shaped clamp to penetrate through the flat anchor pore passage, and then welding a steel bar head at the end head of the U-shaped clamp;
s5, enabling the steel strand to penetrate through a central hole of the flat anchor, enabling the U-shaped clamp to be hung on four hanging points of the front upper cross beam and the main truss upright post by using a chain block, and enabling the chain block to be in a tightened state;
s6, completely removing the suspension rods suspending the template system, and converting the weight of the template system into steel strand stress;
s7, synchronously lowering the templates by 4 chain block lifting hooks until the chain blocks are released to the maximum stroke, then locking anchor clamping pieces at the bridge floor to stress the steel strand, loosening the flat anchor clamping pieces connected with the U-shaped clamps, retracting and lifting the chain blocks again, then locking the flat anchor clamping pieces, tensioning the chain blocks to bear the weight of the templates again, loosening the bridge floor anchor clamping pieces, lowering the templates by using the chain blocks in a step-by-step manner again, and repeating the steps until the templates fall in place.
As a further scheme of the invention: the anchor hole is provided with 4.
