Claim 3:
4. The method according to claim 1, wherein construction process of the middle upright post piles is as follows:
step 2.1: construction preparation, setting out, determining the positions of the piles, drilling and cleaning holes;
step 2.2: lifting and placing the steel reinforcement cages and steel sleeves integrally, and pouring concrete into the pile foundation to the predetermined position for the first time;
step 2.3: installing positioners and anchoring positioning bolts, so as to the center of cross plates of the positioners being coincided with the center of the measured piles;
step 2.4: pouring concrete into the pile foundation for the second time to anchor the positioners; when concrete pouring is completed and the concrete reaches final setting, watering the concrete for curing; lifting the steel pipe posts when the concrete strength reaches 25 Mpa after about 20 hours;
step 2.5: installing the steel pipe posts, and transporting the finished steel pipes directly to a construction site for installation;
step 2.6: pouring concrete into the cup mouths of the pile foundations to the designed elevation of the top of the pile foundation to form the pile foundations;
step 2.7: pouring concrete of C50 into the steel pipe posts, so as to form the middle upright posts through the pile foundations and the steel pipe posts;
step 2.8: retrieving the upper steel sleeves and backfilling dry sand around the steel pipe posts.
