The first biggest hydraulic
hammer utilized at New Sakonnet River bridge, USA <THE
LARGEST RECORD IN USA EVER PILE HAMMER HISTORY BY BRUCE>
|
|

|
|
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. ¥õ1854 of
Long Pile Skirt for ¥õ 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.

At the first stage,
BRUCE SGH-4719 Hydraulic Hammer is being safely laid down on the 2.8 meter
length of Roll Over Cradle anchored on deck of the barge to go to construction
site. To be continued, the
head part of the hammer is laid down on the 2.2 meter of Roll Over Cradle.

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.
