temporary downward hanging croquet mallets are arranged in the top ends of the steel pipes of the truss steel pipe column frames temporarily connected with the bolts;
and a temporary deviation rectifying jack is arranged at the inner joint of the steel pipe for completing concrete pouring.
The utility model discloses the advantage is: the assembled steel tube concrete ultrahigh-lattice pier is a subject structure of a pier by adopting standard segment steel tube columns, flat bracing beams and diagonal bracing beams, two steel tube columns are spliced into a truss steel tube column frame on the ground through the flat bracing beams and the diagonal bracing beams, the truss steel tube column frame is hoisted to the high altitude and is temporarily fixed firstly, and then the truss steel tube column frame is welded up and down after being accurately put in place through debugging. The single truss splicing is carried out on the ground, so that the problems of large hoisting weight and high hoisting height of the four steel pipes of the lattice column of the main bridge can be effectively solved; the steel pipes are hoisted to the high altitude for assembly, so that the difficulties of overlong high altitude positioning and assembly operation time and high safety risk of a single steel pipe can be effectively prevented; realize that ground carries out single purlin concatenation, easily satisfy the hoist and mount requirement, reduce high altitude construction, reduce safe risk's purpose advantage.
