Xuhai Road Station is the 15th station of the first phase of Xuzhou Rail Transit Line 4. It is located within the Huaihai Zongshen Industrial Park plot. The platform is 621.304 m long and 19.7–40.2 m wide. The station has 5 entrances/exits and 2 groups of ventilation pavilions, with shield working shafts at both the north and south ends.

The Xuzhou strata contain limestone with a hardness above 80 MPa. The construction environment is complex and the geological conditions are variable. XCMG rotary drilling rigs take the lead and work with full vigor!

For the station foundation pit construction, bored cast-in-place piles of 1000 mm and 1200 mm diameter were used in the soft shale section at the south end, while 800 mm, 1200 mm, and 1600 mm bored cast-in-place piles were used for the rest. Under specific geological conditions, 400 mm and 650 mm diameter triaxial mixing piles were installed to prevent soil loss between piles.

XCMG XR Series Rotary Drilling Rig

Maximum drilling depth 190 m

Maximum drilling diameter 7.5 m

Powerful chassis stability and a wide range of power head torque

Can meet the diverse needs of different engineering constructions

The three pieces of equipment performed outstandingly after entering the site, with each machine completing an average of two piles per day, ensuring on-schedule project delivery. The equipment's high hole-forming quality and fast pile-forming speed won high praise from the project owner and the construction contractor, who all praised the XCMG rotary drilling rigs as "powerful equipment, efficient construction, and thoughtful service."

XCMG has long been committed to the R&D and manufacturing of underground engineering construction equipment, especially piling equipment, and has gained broad market recognition and customer trust nationwide. XCMG rotary drilling rigs previously participated in the construction of Xuzhou Rail Transit Line 3, and their performance in this project is even more impressive, interpreting "I speak for myself" with strength and once again polishing the "XCMG name card"!
