Horizontal directional drilling is an advanced trenchless construction technology, widely used in various underground pipeline laying projects. It uses a guide drill bit to drill underground according to a predetermined trajectory, and completes hole expansion and pipeline pullback, thereby achieving the goal of laying pipelines without excavating the surface.
This technology originated in the oil drilling industry. After technical improvements, it has been widely used in urban infrastructure, energy transmission, communication cable laying and other fields. It is an important technical means for modern green construction and environmental protection projects.
2. Scope of application of horizontal directional drilling
Horizontal directional drilling is suitable for a variety of geological conditions and engineering environments, especially for the following scenarios:
Highway and railway crossing: avoid the impact of excavation on traffic
River and lake crossing: protect water ecology and reduce damage to the natural environment
Urban underground pipeline laying: such as natural gas, water supply, sewage, electricity, communications, etc.
Infrastructure construction in industrial zones and development zones
Oil and natural gas long-distance pipeline crossing projects
3. Common types of projects
⚪Urban underground pipeline laying
Water supply, drainage, gas, heat, electricity, communication and other pipeline laying
⚪Cross-river/cross-river crossing projects
Laying of oil, gas or water supply pipelines across rivers and lakes
⚪Highway and railway crossing projects
Complete underground pipeline crossing without interrupting traffic
⚪Industrial park internal pipeline network construction
⚪Pipeline laying in ecological areas such as farmland and forest land
Reduce damage to land and vegetation
4. Product advantages of horizontal directional drilling
Compared with traditional excavation construction methods, horizontal directional drilling has the following significant advantages:
1. Environmental protection and energy saving
Does not damage the natural and cultural environment such as surface vegetation, roads, rivers, etc.
Reduces earth excavation and reduces carbon emissions
2. Efficient construction
Short operation cycle and high degree of automation
Can achieve long-distance and large-diameter pipeline laying
3. Strong adaptability
Can be constructed under complex geological conditions (such as soft soil, sand layer, rock layer, etc.)
Flexible response to different terrains and obstacles
4. Controllable costs
Reduce the cost of restoring the surface (such as road repair, greening reconstruction)
Reduce construction risks and later maintenance costs
5. Safe and reliable
Avoids safety hazards such as landslides and traffic interruptions that may be caused by traditional excavation
High quality of pipeline laying and long service life
