New quay wall at Watchet for TMS

This week we're involved in an exciting project in Somerset for TMS installing a new sheet piled wall at Watchet Marina.

One of our RTG RG21T telescopic leader rigs is working on a jack-up barge fitted with a Eurodrill DKS 50/100 twin rotary head with 18.5 m long 610 mm diameter casing and 550 mm diameter CFA augers inside pre augering through the rock initially. The casing acts as a core barrel and advances ahead of the auger which follows behind pulverising the rock. We then switch to MR150AVM vibro using the RTG patented ACS system and install the 18 m long pairs of AZ26 sheet piles to level.

All serviced by one of our Sennebogen 650HD, 50 tons lattice boom crawler cranes from the quay.
