Hollow stirrup-free friction pile for bridge and construction method of hollow stirrup-free friction pile

The hollow stirrup-free friction pile for the bridge comprises a base body and three sets of pile bodies which are fixed to the bottom end of the base body and distributed at equal intervals, the outer walls of the multiple sets of pile bodies are sleeved with connecting plates, and the connecting plates are connected to the bottom end of the base body through limiting mechanisms and used for limiting inclination of the pile bodies; the limiting mechanism comprises a positioning block, a threaded rod, a rotating ring and a rotating nut. The threaded rod is fixed to the bottom end of the base body. According to the hollow stirrup-free friction pile for the bridge and the construction method of the hollow stirrup-free friction pile, the connecting plates, the positioning blocks, the threaded rods, the baffles, the rotating rings, the rotating nuts and the binding steel bars are combined for use, the connecting plates are arranged on the multiple pile bodies in a sleeving mode, at the moment, the threaded rods c
