DRIVING PRECAST CONCRETE PILES FOR A NEW BIO-MASS PLANT
Project Description
SCOPE OF WORKS 667 No. 300/350sq Precast Concrete Piles
EQUIPMENT Junttan PM20, Banut 11
CONTRACTOR Galliford Try PLC
CONSTRUCTION PERIOD June 2016
Aarsleff Ground Engineering were awarded the piling works
from main contractor Galliford Try PLC. The project will form part
of a new Bio-Mass energy facility located on land leased from
Associated British Ports (ABP) in the vicinity of King George
Dock, Hull. The Bio-Mass Plant is part of an Advanced Thermal
Treatment plan designed to process wood chip and biomass
waste.
Specifically, Aarsleff designed and installed 667no 300/350sq
precast concrete piles supplied in two segments interlocked with
a full mechanical pile joint.
The piles were founded within dense sands/gravels at 25
to 28metre below piling platform level. Aarsleff carried out 3
preliminary static load tests which were undertaken during the
initial weeks, followed by dynamic load testing during numerous
visits to site. Driven piles were installed within 18m of an existing
brick culvert with vibration monitoring undertaken to ensure the
levels of vibration did not exceed the limits of vibration imposed
by Yorkshire Water.
Aarsleff were on site for 10 weeks with its Junttan PM20 and
Banut 11 Driven Piling Rig. Project commenced in June 2016.
