Highly Anticipated Photo Finish wraps up Tunneling at Massive Metro
On September 28, 2016, Bangalore’s last TBM for the city’s metro rail project broke through, marking the end of 
TBM tunneling on the Namma Metro phase 1. The Robbins-operated machine, known as “Krishna”, bored a 750 m (2,460 ft) drive through challenging conditions between Chickpet and Majestic stations. Cleanup and final commissioning of the tunnel will be completed in 2017, and is the last obstacle before owner Bangalore Metro Rail Corporation Ltd. (BMRCL) can open the Malleswaram-Majestic link. The TBM’s sister machine, “Kaveri”, completed a parallel tunnel in June 2016.
The success follows a gauntlet of challenges on the two tunnel sites. Due to severe delays on the original tunnel drives, Robbins was approached and asked to take over the operations of the remaining two competitor-manufactured TBMs in February 2015. After obtaining agreement from the project owner and the contractor, Robbins took over the responsibility for all aspects of the underground operations. “We provided a team of over 60 staff including TBM operators, TBM technicians, ring builders, a grouting team, and more. We were also responsible for running surface installations and equipment such as the grout batching plant, gantry cranes and power supply. Contractor Coastal Projects Ltd. (CPL) provided a team of people including surveyors, QC engineers, and loco operators who reported directly to our site management team,” explained Jim Clark, Projects Manager for Robbins India. 
The Robbins crew carried out tunneling operations while the Chickpet station was being constructed around them to mitigate delays incurred before they took over project operations. The project’s most difficult challenges included a low overburden and unconsolidated ground along the alignment, and the discovery of several uncharted wells directly on the alignment. Difficult ground frequently prevented proper pressurization during cutting tool replacement, requiring a grout solution to be pumped in to fill voids and left to cure. Initially the curing process took up to 36 hours, but with improved application methods this was reduced to a 12-hour curing time.
Another challenge involved the sensitive building structures along the tunnel path. Issues with surface vibration, explained Clark, required that cutterhead speed be limited to 1.8 RPM during the day shift and 1.2 RPM during the night shift. Despite the obstacles, the TBMs advanced at rates of up to 50mm (2 in)/min in highly weathered rock.
“This is an industry first, wherein a TBM manufacturer has utilized their in-house expertise and knowledge to take on this level of responsibility for a project,” said Clark, addressing the magnitude of the successful breakthroughs. “The fact that it was ‘a first’ and we were successful in bringing this high-profile project back on track is a great achievement for The Robbins Company.”
Now that tunneling is complete, the North and South runs of the Namma metro will be connected–a line that, once in service, will carry an estimated 40,000 passengers daily. It is anticipated that Phase One of the metro will be opened in its entirety in 2017.

October 6, 2016 – LAKE MILLS, Wisc. – HammerHead Trenchless Equipment, a Charles Machine Works 
company, has introduced the powerful, new HammerHead HydroGuide® HG1200 winch optimally designed to be more efficient and easy to use in pipe-bursting, slip-lining or slitting applications. This new iteration of the popular HydroGuide line of winches features a patented, self-deploying hydraulic downrigger, improved performance and additional safety features.
While other winches on the market require manual assembly of heavy, bulky components, the HG1200 makes setup easy with its industry-changing hydraulic downrigger. With the touch of a button, users are able to automatically deploy the boom down hole and can fine-tune the depth up to 18 feet without having to jack up the machine. With the hydraulic boom, setup and teardown take just minutes, which saves valuable time on a job site.
A key feature of the new HG1200 winch is its precision controls. Not only can users adjust the boom to any depth, but they also have total control of the line speed and pressure. Pull force can be set anywhere between 0.5 to 12 tons, and the line speed can be set anywhere between 0 to 111 feet per minute.
“We know job conditions and specifications can vary greatly so we created a machine that can be infinitely adjusted within its parameters to fit each individual job exactly,” said Josh Hood, HammerHead product line manager. “This level of control is critical to the success of gasline slitting applications, which was a driving factor in the improvements we made from the previous version. We worked to create a winch with the necessary power and agility for a wide range of situations to ensure customer success.”
The HG1200 winch is powered by the Kubota D1105, a vertical, water-cooled, four-cycle diesel engine that complies with Tier 4 emission regulations. This lightweight, dependable engine increases the unit’s performance and fuel efficiency. The radial piston motor provides a smoother, more consistent pull.
The HG1200 has several configuration options available from the factory to meet specific customer needs:
- Optional Tracks – The optional track-mounted HG1200AT reaches difficult areas on your job site that the standard, wheel-mounted units cannot.
- Electrical Strike Identification system (ESID) – The optional ESID system is designed to provide additional safety on the job site when working near adjacent underground utilities.
- Hydraulic levelling jacks – The hydraulic option allows users to easily adjust downhole access, improving project efficiency.
The HammerHead HydroGuide HG1200 winch is available directly from HammerHead Trenchless Equipment or from authorized dealers worldwide. Authorized dealers can be found on the web at www.hammerheadtrenchless.com or by calling 800.331.6653. (International: + [1] 920.648.4848).

Electro Scan Inc. has completed data integration between its flagship sewer condition assessment solution and the 
Innovyze® InfoMaster for Sewer product.
Electro Scan’s breakthrough technology evaluates 360-degrees of a pipe wall to accurately locate and measure defects in gallons per minute (GPM) or liters per second (l/s).
Recent studies indicate that 70-100% of defects are typically not found by legacy inspection techniques, such as closed-circuit television (CCTV) inspection, smoke testing, dye flood testing, laser profiling, and acoustic sensors.
Recommended to assess and certify pre- and post-rehabilitated pipes, a new chapter was recently added on Electro Scanning Inspection to the industry’s leading training manual, Operation and Maintenance of Wastewater Collection Systems, Seventh Edition, Volume One (2015), in accordance with ASTM F2550.
“We are delighted to integrate our game-changing pipe condition assessment solution with the leading business analytics solution for the wastewater industry,” states Chuck Hansen, Founder and CEO, Electro Scan Inc.
“The Innovyze® family of smart network modeling and asset management solutions continues to be the standard platform for existing and emerging diagnostic tools,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, Dist.M.ASCE, NAE, President, COO and Chief Innovation Officer of Innovyze.
“We look forward to offering this new layer of condition assessment data to help our clients in their sewer rehabilitation decisions,” continues Boulos.
Electro Scan’s Critical Sewers® cloud application allows for up-to-the-minute monitoring of sewer evaluations, lining projects, point repairs, and new construction projects, while crews are still in the field.
Clients can easily identify pipe-specific problems before rehabilitation project acceptance.
Wirelessly transmitted to the Company’s award winning cloud application, defect flows are reported in minutes and incorporated into Innovyze® InfoMaster for Sewer product for display and analysis.
Since Electro Scan’s advanced low voltage conductivity technology does not rely on operator interpretation, third-party data analysis, or independent judgment, a key advantage is its ability to automatically provide specific location, size, and estimated flow for each defect and total pipe.
Customers wishing to utilize Electro Scan’s decision support data must be licensed users of Innovyze® InfoMaster for Sewer and Electro Scan’s Critical Sewers® cloud application, including associated integration module.
Once data is accessible, Electro Scan defect flows may be highlighted by location and severity by Innovyze® InfoMaster for Sewer, including the identification of defective joints, cracks, and leaking service connections, compared to CCTV inspection results.
Electro Scan and Innovyze® users can show pipe defects ranked by highest GPM and gallons per day per inch diameter mile (GPD/IDM), utilizing Innovyze’s 1D and 2D modeling and mapping features within Innovyze® InfoMaster for Sewer product.
Plans include the integration of Electro Scan’s 4-in-1 water leak detection probe with Innovyze® InfoMaster for Water to assess pressurized water mains.

AURORA, IL- TT Technologies recently introduced a new cutterhead configuration for its Grundoburst static pipe 
bursting system. The new configuration consists of three specially designed bladed, roller cutterheads in succession. The bladed roller cutting head configuration allows contractors to burst/split large diameter steel and ductile iron pipes when used with larger Grundoburst static bursting systems. The new special cutterhead design allows for a smoother host pipe cut and greater protection for the new pipe.
Pulled by a hydraulic bursting unit, the cutterhead’s special cutting wheels split the host pipe. An attached expander spreads and displaces the split pipe into the surrounding soil while simultaneously pulling in the new pipe. The Grundoburst system features Patented QuickLock bursting rods that are linked together not threaded. This saves time, prevents twisting and extends the life of the cutterhead over threaded bursting rods.
