Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The embodiment of the present application provides a formwork tie rod for hydraulic pier wall construction, which solves the problem that the formwork tie rod and embedded parts exposed outside the hydraulic pier wall cannot meet the requirements of appearance and flatness.

[0026] Both ends of the first screw rod 1 are respectively threadedly connected with threaded barrels 2, a rubber pad 3 is padded at the outer end of the threaded barrel 2, the inner end of the second screw rod 4 passes through the rubber pad 3 and is threadedly connected with the threaded barrel 2, the gasket 5 is sleeved on the second screw rod 4, and the nut 6 is threadedly connected with the second screw rod 4.

[0027] The rubber pad 3 contacts the inner wall of the formwork 7, the gasket 5 contacts the outer wall of the formwork 7, and tightening the nut 6 can realize the support and fixation of the formwork 7.

[0028] As Figures 1 to 3 shown, a concrete cushion block 8 is sleeved outside the threaded barrel 2, the outer end of the concrete cushion block 8 contacts the rubber pad 3, and the inner end contacts the outermost pier wall steel bar 9.
