Thrust boring, (also referred to as pipe jacking or trenchless pipe installation) involves the use of steel pipes which work in push within the ground without using a trench on the ground surface. This is a perfect process for laying pipe crossings under the road, building and railway (where the open excavation is not possible or restricted due to heavy costs).
What Is Thrust Boring?
Thrust boring is a HDD technique. It relies on hydraulic power to push steel casing pipes through the earth. The drilling process uses an auger to extract the soil, or it can be done by hand. Safe and efficient, especially in tight or urban areas.
The for the a through installation is generally:?
Water supply lines
Gas pipes
Electrical conduits
Drainage and sewage lines
Telecommunication ducts
Since the surface of the ground is left undisturbed, there’s little interference with traffic, scenery or existing buildings.
How Does It Work?
Here is a simplified explanation of how thrust boring works:
Entry and Exit Pits: If the initial and final positions are defined, the two shallow pits are dug.
Machine Installation: The thrust boring machine is installed in the entry pit.
Pipe Pushing: Steel Pipe is pushed into place under the ground by hydraulic thrust.
Excavation: The soil in the front of the entrance of the pipe is removed with the help of auger, spade etc.
Pipe Extension: As one pipe section moves forward, a new one is welded or joined behind it.
The accuracy of this method varies with soil type, pipe diameter, and operator skill —but it’s extremely reliable when applied properly.
Advantages of Thrust Boring
No dig: Doesn’t require open digging.
Easy Installation: Reduces installation time for site preparation and restoration.
Cost-Efficiency: Minimizes labor and surface repairs.
Eco-friendly: Minimize destruction on the site and its surroundings.
Silent Operation: Great for urban and residential areas.
Why to Choose the Thrust Boring?
Aio thrust boring is suitable for:
When working under highways or rail track or underneath structures.
In built-up areas where open excavation is prohibited.
For laying pipes of large diameter up to a few hundred meters in length.
Whether you’re a utility contractor or municipal engineer, thrust boring provides a clean and cost-effective way to get the job done underground.
