Underground infrastructure projects are becoming increasingly important as cities continue to expand. Installing water pipelines, gas pipelines, fiber optic cables, and power cables without damaging roads or landscapes has become a top priority for contractors. This is where Horizontal Directional Drilling (HDD) machinesplay a vital role.

Horizontal directional drilling is the mainstream trenchless construction technology for pipeline engineering. Stuck drill is the most common downhole fault that hinders construction progress and causes economic losses, which mainly occurs during hole reaming and pipeline pullback. Focusing solely on stuck drill issues, this paper analyzes the hazards, root causes, on-site identification methods, emergency solutions and pre-construction prevention measures, providing practical references for field construction and management.

As urban construction demands cleaner and quieter foundation solutions, Hydraulic Static Pile Drivers have become an increasingly popular choice. Using hydraulic pressure rather than impact hammering, they deliver efficient pile installation with minimal noise and vibration. In this article, we explore the working principle, advantages, and applications of hydraulic static pile driving technology.

In horizontal directional drilling projects, most construction failures, delays and equipment wear are caused by mismatched rig models, drill tools and construction technologies for local geological conditions. Reasonable formation adaptation is the core premise of stable and efficient trenchless construction.

In horizontal directional drilling (HDD) trenchless construction, most operators focus on machine pullback force, torque and drill tool configuration, while ignoring that the mud system determines the success of the whole drilling project. 

When selecting a deep foundation method for construction projects, engineers and contractors often compare jack-in piles and bored piles. Each method has its own strengths, limitations, and ideal application scenarios.

So, which one is better?

The answer depends on project conditions—but in many modern urban projects, jack-in pile foundations are increasingly preferred due to their efficiency, environmental benefits, and superior quality control.

In the Laoha River basin of Chifeng, Inner Mongolia, the geological conditions are complex and river sections are wide. As a critical line in the national petroleum and natural gas pipeline network, it requires highly efficient, safe, and environmentally friendly construction. The Goodeng GSEE12000L ultra-large electric HDD demonstrates excellent performance, successfully completing the non-excavation river crossing and providing a reliable solution for urban and cross-region pipeline construction.

1. During construction, avoid connecting large-diameter drill rods with small-diameter drill rods (i.e. mixed use of different diameter drill rods), so as to prevent the small-diameter drill rods from fracture or deformation due to insufficient structural strength.
