Tunneling endeavors present a particular set of challenges that make each scenario a project of its own. Constricted space, multiple rock faces with varying compressive strengths, and other geological conditions create unique problems that must be solved by the construction team.
Diagnosing the particular landscape and determining the correct equipment to handle the job are key attributes in delivering a winning bid for these complex projects.
The right combination of equipment and diligent maintenance can help you meet your deliverables efficiently and on schedule. This blog post will look specifically at cutterheads and some of the distinct advantages they provide over hydraulic hammers during tunneling projects.
Low Start-Up Costs
A key to any successful project is identifying areas to lower costs without sacrificing high-end quality.
Selecting a cutterhead for your tunneling project does exactly that. With lower start-up costs than hydraulic hammers, you’re project is off to a great start right off the bat.
In addition to lower start-up costs, for the majority of material that you’ll encounter during a tunneling project, a cutterhead is going to return a higher rate of production.
Tunneling is one of the most demanding situations for hydraulic hammers and it is not uncommon for them to break. The combination of lower cost and higher production is a major point of advantage for cutterheads.
Increased Flexibility and Precision
In the process of tunnel work, there can be a wide variety of conditions that a crew may encounter. Cutter heads afford operators with a greater sense of control, allowing them to operate more efficiently. Cutterhead designs are getting increasingly better at predicting the challenges of tunnel work.
The improved designs give them a superior versatility to hydraulic hammers. This greater versatility improves cutterheads abilities to operate in confined spaces at a high performance level.
Cutterheads consistently produce smoother, safer, and more stable walls than hydraulic hammers. Additionally, cutterheads reduce the amount of overbreak that your team will experience. With a cutterhead, your team can be confident in the stability of its trench walls.
Cutterheads maximize efficiency by creating smooth walls and doing a better job than hydraulic hammers of creating fines. The smaller debris can often be used on-site as backfill.
Less debris means it is easier for the tunneling project to continue working and less money spent on removing debris.
Operationally, cutterheads perform at low speeds but have high torque which also improves their efficiency and lessens the likelihood of breakage.
These three areas of advantage demonstrate the viability of cutterheads as an alternative to hydraulic hammers in tunneling projects. If you are interested learning more about applications cutterheads can be used for, check out our free eBook – The Ultimate Guide to Rock Grinding.
