The biggest hydraulic hammer utilized at New Sakonnet River bridge, USA

The replacement of the Sakonnet River Bridge, which carries nearly 40,000 cars per day and provides a critical transportation system link between Massachusetts and Rhode Island, is necessary to meet current highway design standards for shoulder width and structural capacity. A, 3,160-ft-long, 4-lane bridge will be built along an alignment located immediately south of the existing bridge, which will remain in operation during construction.

Standing where the new bridge will soar overhead, State officer Carcieri and other officials marked a milestone in the long process to replace the 53-year-old bridge. Construction work under way and is projected to open to Route 24 traffic in spring 2012.

It is extraordinarily important to towns on both sides of the span. The project will replace the old span with one directly to the south. The new bridge will include a 13-foot sidewalk for pedestrians and bicyclists, a passage underneath for boats more than twice as wide, and a boat ramp on the Tiverton side. More importantly for motorists, the new bridge would end a detour of up to 30 miles for trucks heavier than 18 tons. The weight restriction also kept fire trucks in Portsmouth and Tiverton from helping in emergencies in each other’s communities.
It is the most expensive bridge project in state history and is projected to create up to 140 construction jobs and 330 indirect jobs, according to RIDOT. “We need the jobs,” Carcieri said. It will be built by Warwick, R.I., company Cardi Corp., which is also building the Providence River Bridge, which carries Interstate 195.

Decorative features of the bridge have been preserved, however. LED lights — which according to renderings will be red, blue or green — will highlight the bridge’s piers in the river, and red lights will be attached vertically to light posts that line the center median. The new bridge will be 65 feet, the same height as the current span. The new bridge is expected to open in 2012.

Community benefits ;
* Improved public safety and seismic protection
* Increased transportation capacity for existing and future traffic volumes
* Added bicycle and pedestrian path, separated from vehicular traffic by safety rails
* Replacement bridge alternative minimizes the cumulative impacts to the environment

Assembling the BRUCE SGH-4719 Hydraulic Hammer in Vertical Position

Because of its heavy weight and extraordinary length measured in total 86.6 ton (19100 lbs) and length, 13 meter (43 ft), assembling the SGH-4719 Hydraulic Hammer was progressed on site.
Assembling it related to this job completed with a crane suspended type from the bottom in order.
 

A four lump of Ram Segment are put together to fit with the Ram Assembly.
Inside dia. φ1854 of Long Pile Skirt for φ 72 inch Steel Casing is being assembled with Drive Cap.
Finally, 2.9 meter of Cylinder Housing is being put together with Ram Housing.

BRUCE SGH-4719 Hydraulic Hammer accomplished 72 inch Casing Pile job

A major US contractor of this project used BRUCE SGH-4719 Hydraulic Hammer featured with 89.3 tom.m (876 kJ) of maximum potential energy,1.9 meter (6.23 feet) of maximum stroke and is powered by 1100 HP (820 kW) capacity of power pack model PQ-1200 for the first time since in the US bridge construction history, specializes in marine and general construction, marine equipment rental and sales to include ABS and inland barges.
The Company has both the expertise and the equipment to provide the highest levels of services and products available
in the marine industry.

This project was located in Tiverton, Rhode Island, USA. This heavy and marine construction project involved pile driving of 72 inch diameter and 200 feet long (join 150 ft + 50 ft) steel casing piles for foundation support for bridge structures, with retaining the ground shake along the new Sakonnet River Bridge retaining more increased span on both side of the bridge for the future transportation volume. The entire pile driving operation was controlled by the smart and sophisticated Remote Control Box ensuring the electrical and hydraulic movements to be seen by operator’s visual check.

BRUCE SGH-4719 will be the most powerful hydraulic hammer by its pile driving value.

BRUCE SGH-4719 hydraulic hammer was driven by the uniquely designed and built PQ-1200 model of Power Pack which equipped with increased cooling capacity of Diesel Engine for a constant stability of the job performance. PQ-1200 Power Pack with closed loop type and lockable sheet metal housing removal for easy component access, performed 1250 liter per minute of Hydraulic Flow Rate by the reliable Rexroth and Doosan Pump to drive adequately to 72 inch Steel Casing Pile.
Powerful hydraulic Flow Rate enables Ram Stroke to do reciprocating motion as much as specified up to 1.9 meter movements of the hammer resulted in 89.3 ton m (876KJ) of Maximum Potential Energy.

Energy Monitor system was utilized for BRUCE SGH-4719

Before everything else, the most attractive merit of using this device account for enabling the field crew to take immediate action even far from the distance.
IEA is essential for a driven pile foundation to estimate hammer energy efficiency at a real time basis of the driven pile working. it is also possible to adjust IEA system to fit adequate stroke height without checking the making line on the hammer.
The IEA system will give the engineer the option of determining the penetration depth for a single pile and it assesses hammer energy capacity, cumulative blows, blow rates etc, at a real time data interpretation.
When the engineer is present on site by the IEA system, it displays all the job data and results, therefore, a field crew can evaluate the data such as blows per step, blow rate and energy per step through it. It is an excellent way of protecting both pile materials and hammers.
