Design Drawing of 5000X2400 Section Pier Shaft Formwork

2. The main bridge of the superstructure is an 80+80m double hole prestressed concrete partial cable-stayed bridge, and the approach bridges are 1X32m and 4X32m prestressed concrete constant cross-section box continuous beams, respectively. The substructure is a reinforced concrete U-shaped abutment, slab pier, and bored pile foundation. 3. Design load of this bridge: urban level A, automobile - over 20, trailer - 120 checking calculation. 4. The clearance under the bridge along the river is not less than 3.5m.

1、 Project overview: A super large bridge project is located in a town of Putian City, starting from DK100+348.713 and ending at DK103+167.940. There are 87 piers in total, and the height of piers ranges from 4m to 12m, all of which are straight slope rectangular piers. Most of the plane dimensions are 3.2 × 7.2m, 33 # and 36 # are 3.4 × 7.2m, 34 # and 35 # are 3.4 × 7.6m. Piers with a height of less than 6m are solid piers, and those with a height of 6m and above are hollow piers.
