Construction method of steel trestle

The invention relates to the technical field of building construction, in particular to a construction method of a steel trestle, which comprises the following steps of: 1, performing construction survey; 2, inserting and driving steel pipe piles, namely uniformly arranging and inserting and driving two rows of steel pipe piles on a riverbed along the direction vertical to the flowing direction ofthe river in the following inserting and driving manner: A1, inserting, dotting and positioning; a2, cofferdam construction; a3, the steel pipe pile is in place; a4, inserting and driving steel pipepiles; a5, the pile head is cut off; a6, the cofferdam is dismantled; 3, connecting the steel pipe piles; 4, mounting an upper structure; and 5, the steel truss girder is installed. The steel trestlehas the effects that the influence of water flow on the steel pipe pile when the steel pipe pile is driven in can be reduced, the steel pipe pile is positioned more accurately, the steel pipe pile isprevented from deviating, th
