Specification

XR220 rotary drilling rig

The rotary drill is used for drilling holes in rock formations with a hardness coefficient of f≤6 in open-pit mines, and can also drill hard interlayer rocks with a hardness coefficient of f=7-11. When drilling, a rotary torque and axial pressure are applied to make the drill bit rotate and feed to cut the rock.A bridge spans across the local waterway.

The bridge center pile number is K161+656.425, the total length is 1913.45m, and it consists of three parts: the main bridge and the south and north approach bridges. It adopts a two-part separation type. The foundation of the main bridge is bored cast-in-place piles and rectangular abutments; the lower structure is a hollow thin-walled pier, and a pier cap is set on the top of the transition pier.

The foundation of the approach bridges on both sides is bored cast-in-place piles, and tie beams are set between the piles; the lower structure is a cylindrical pier, and a cap beam is set on the top of the pier. The abutment is a ribbed abutment.
