The directional drilling of XCMG XZ11600 through hard rock was successfully towed back in one attempt!

Hard rock strata, a one-time success!

The XZ11600 has once again accomplished a super project!

Recently, XCMG's XZ11600 horizontal directional drilling rig made an appearance in Qingdao, contributing to the gas pipeline laying project of the eastern trunk line of Shandong Pipeline Network. The construction pipe diameter is 1219mm large-diameter steel pipe, and the total construction length is 1000m. During the drilling and towing process, the project needs to pass through hard geological conditions with a rock stratum strength of 80Mpa. Additionally, it requires crossing a river, and the geological and terrain conditions are complex, making the construction quite challenging.

XCMG XZ11600 super-large tonnage horizontal directional drilling rig, with powerful performance and intelligent operation, perfectly solves engineering problems! The rock geological directional drilling crossing was successfully towed back in one go! Picture

The XCMG XZ11600 horizontal directional drilling rig is an intelligent super-large tonnage horizontal directional drilling rig independently developed by XCMG Foundation to meet customer needs. It features high rotational speed, large torque, strong pushing and pulling force, and high pushing and pulling speed. The maximum backdrag force can reach 11600 kN, and the maximum rotary torque is 260,000 N·m. It is suitable for long-distance, high-difficulty, and complex terrain construction conditions, and can meet the requirements of large pipeline projects and rock geological construction projects.

During the construction process, the XCMG XZ11600 horizontal directional drilling rig is equipped with a three-engine power system, featuring high torque and high rotational speed. Coupled with multi-speed stepless speed regulation technology, the drilling rig not only has strong power, a wide range of geological adaptability, but also is economical and fuel-efficient, effectively reducing construction costs! The embedded load on-demand distribution technology enables dual-engine start-up, efficiently enhancing to the maximum torque and maximum push-pull force. The engine power is fully utilized, ensuring efficient construction.

Meanwhile, the newly upgraded mechanical gripper equipped on the horizontal directional drilling rig is both intelligent and efficient. The one-click leveling function simplifies the construction process. The gripper pressure and flipping speed can be adjusted according to the actual working conditions. The automatic pipe drop mechanism can enable the drill pipe to slide down to the ground automatically, saving the cost of manual disassembly.

In terms of intelligence, the entire machine adopts a modular design, making quick disassembly, replacement and maintenance convenient. It has established a push-pull speed adaptive cruise reaming function based on load feedback, which can effectively improve the reaming efficiency and extend the service life of the working device. The push-pull sliding drill frame, combined with the rocker arm structure, makes the adjustment of the drill frame's entry Angle into the soil simple, convenient and safe.

During the construction process, the XCMG XZ11600 adjusted the main construction parameters such as rotational torque and push-pull force through the built-in digital display system. The owner of the machine can remotely view the construction records and data on the mobile version of the Drill Cloud. XCMG's deep technical team can conduct data analysis in the cloud and provide real-time support and guarantee for construction.

This project is another major construction case for XCMG XZ11600 following its participation in the supervision of the hidden danger rectification and governance project of the Three Rivers crossing in Shandong Province. The achievement has increased by one. The client highly praised the efficiency and stability of the equipment. It is believed that the superior performance of XCMG products will provide a solid guarantee for the overall success of the crossing project!
