How To Apply Super-large Tonnage Rotary Drilling Rig in Deep Pile Engineering

In the construction of large buildings and infrastructure, deep pile engineering is very important. The super tonnage rotary drilling rig plays an irreplaceable role in the field of deep pile construction with its powerful drilling capacity. Below, we will introduce the specific application of this kind of drilling rig in deep pile engineering.

1. Equipment selection and adaptation conditions: Deep pile engineering geology is complex, need to choose equipment according to the actual situation. For example, in the construction of Xiamen Metro ultra-deep air shaft, due to rock fragmentation and the alternation of soft and hard, the construction side selected Zoomlion ZR360L rotary drilling rig, which has large torque and high reserve coefficient, and successfully dealt with complex working conditions.

2. Efficient drilling support schedule: XUGong XR468F back rotary drilling rig in Guangzhou Zhengtian high-speed construction, the rod, drilling and other operations in one go. It is equipped with a high-torque power head and advanced hydraulic system, which can complete a pile in an average of 24 hours, greatly improving construction efficiency.

3. Stable structure to ensure safety: for deep pile operation, equipment stability is very critical. Zoomlion ZR360L enhances the construction stability through the design of large mast section and double boom quadrangle amplitude changing mechanism, so as to avoid the impact of shaking on pile quality and construction safety.

4. Intelligent control to reduce the threshold: some ultra-large tonnage rotary drilling RIGS are equipped with intelligent control systems, such as XR468F one-click correction, bottom protection and other functions, which not only reduces the difficulty of operation, but also automatically monitors and adjusts drilling parameters to improve construction accuracy.

5. Supporting process coordination: In the construction of Zhuhai-Zhao high-speed railway Xijiang Extra-large bridge, Xugong adopts the construction method of steel casing and extra-large rotary drilling to ensure one-time hole formation. In addition, through the mud wall protection and other supporting technology, to maintain the stability of the hole wall, to ensure the smooth construction.

6. Meet the requirements of environmental protection: Nowadays, the construction of environmental protection requirements are increasingly strict. Xugong does a good job in the mud transport during deep pile construction, protects the water source of the construction site, reduces the negative impact on the environment, and realizes the coordinated development of project construction and environmental protection.

In short, with its unique equipment performance, intelligent control system and supporting construction technology, the super-tonnage rotary drilling rig has played a key role in the deep pile project, which has effectively promoted the smooth construction of various large-scale infrastructure. In the future, with the continuous innovation of technology, it will have a broader application prospect in the field of deep pile engineering.
