How Can Trenchless Drilling Help You to Enhance Your Project Profitability?

INTRODUCTIONS:
Trenchless technology is a type of subsurface construction work that requires few trenches or no continuous trenches. It is a rapidly growing sector of the construction and civil engineering industry. It can be defined as “a family of methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities.
Trenchless construction includes such construction methods as tunneling, micro tunneling (MTM), horizontal directional drilling (HDD) also known as directional boring, pipe ramming (PR), pipe jacking (PJ), moiling, horizontal auger boring (HAB) and other methods for the installation of pipelines and cables below the ground with minimal excavation. Large diameter tunnels such as those constructed by a tunnel boring machine (TBM), and drilling and blasting techniques are larger versions of subsurface construction. The difference between trenchless and other subsurface construction techniques depends upon the size of the passage under construction.
Over time, methods used in trenchless directional drilling have evolved to keep up with the ever-evolving challenges within the industry. As obstacles such as space restrictions, environmental impacts, rising costs, and timeline restrictions have become more prominent, we are able to combine the advantages of horizontal directional drilling (HDD) and micro-tunneling to open up new opportunities, applications and solutions. From managing risks to improving timelines, and from environmental stewardship to substantial cost savings, the undeniable benefits make the obvious solution for your next trenchless crossing project.

COST SAVINGS
• Less drilling mud, resulting in less management and drilling mud disposal.
• Trenchless Drilling technology leads 90% less bentonite slurry than horizontal directional drilling.
• The significant cost of boom cranes is eliminated.
• Project schedules are improved.

RISK MITIGATION
Trenchless Drilling method eliminates several risks typically associated with horizontal directional drilling under rivers, roads and rail crossings:
• The drill hole is supported at all times with the product pipe, eliminating the risk of the drill hole collapsing.
• The drill hole is not supported with bentonite, vastly reducing the risk of frac-out.
• One-pass drilling system eliminates the danger and additional time associated with the HDD multi-pass, back reaming and swabbing processes.

ENVIRONMENTAL STEWARDSHIP
• The environmental impacts associated with the Trenchless Drilling installation, in comparison with other drilling methods, are greatly reduced:
• Along with a lower risk of frac-out, Trenchless Drilling technology also reduces the amount of drilling mud and water required. This method is substantially quieter and requires less fuel than the equivalent HDD.
• Less working area is required on either side of the crossing – decreasing the environmental footprint.
