Rotary drilling drill construction case | Fenghua Siming Road (Jinfeng Avenue-Fangxin Road) Rapid Transformation Project

Project Overview:

The rapid transformation project of Fenghua Siming Road (Jinfeng Avenue-Fangxin Road) starts from the west of Jinfeng Avenue (K1+420) in the west to Fangxin Road (K5+893.4) in the east, with a total length of about 4.5km. The project adopts the construction form of "main line elevated + ground auxiliary road", the main line adopts the expressway standard, and the ground auxiliary road adopts the first-class highway standard (taking into account the function of urban roads); The main line pier number of this project: PM0O# pier - PM114# pier. There are 6 ramps involved, 1#~6# ramps, 1# ramps and 2# ramps, 5# ramps and 6# ramps are two pairs of parallel ramps, and 3# ramps and 4# ramps are directional ramps; It involves 7 ground bridges, Xuehua Bridge and No. 2 Bridge of Shixi Line are demolished and newly built for the old bridge, Shangzhang Bridge, No. 1 Bridge of Shixi Line, No. 3 Bridge of Shixi Line, and Zhengjia Bridge are used for the old bridge to be widened, and the bridge in the Development Zone is the reconstruction and utilization of the bridge deck.

The implementation of this project includes road engineering, bridge engineering, foundation pit engineering, pipeline integration, rain and sewage drainage pipes, street lighting, monitoring engineering, traffic engineering, revetment engineering, landscape engineering, construction engineering, Baotong engineering and ancillary facilities. The contract cost is about 1,143.8 million yuan, and the planned construction period is 1,080 calendar days.
