Bohren und Vibrieren mit nur einer Maschine? -Kein Problem! 🤩 In Surrey, England, durfte sich unsere #ABI #TM20 doppelt beweisen. Durch die dortigen Bodenverhältnisse war ein Vorbohren von einer Tiefe von 8 Metern nötig, bevor unser Vibrator MRZV 26VV die 11 Meter langen Spundwände einbringen konnte. ✨ Mit unserem Docking-System D6 war es kein Problem, das Arbeitsgerät an der #spezialtiefbaumaschine in kürzester Zeit zu wechseln. 💪 Das #MOBILRAM konnte auch mit unserem serienmäßigen Efficiency Drive glänzen. Dieser spart Kraftstoff, reduziert Lärm und Abgase und verringert den Verschleiß an Dieselmotor, Pumpen und Hydraulik. 🌱 Thanks to ABI EQUIPMENT LIMITED and Ivor King - The Piling People for the update and the pics! 📸 #abigruppe #spezialtiefbau #abigroup #specialcivilengineering #specialcivilengineeringmachine
The M25 Junction 10 with the A3 at Wisley in Surrey is the busiest section of the motorway with more than 300,000 vehicles passing through it each day. The junction is currently being upgraded to improve traffic flow, reduce congestion, and improve safety. Ivor King - The Piling People have been working on site undertaking sheet piling work using one of our ABI TM20 Mobilrams. Ground conditions on site have meant that the pile line has required pre-augering using an Ø600mm CFA auger string to a depth of 8 meters. The 11m long AZ26-700 king piles, and AZ12-770 sheet pile pairs were then installed to the required depth using the TM20’s state-of-the-art MRZV36VV variable static moment, variable frequency vibrator. Switching between pre-auger work and pile installation takes only a matter of minutes thanks to the rigs D6 Rapid Docking System. This is not only very fast, but it also avoids any working at height issues and ensures correct/clean connection to the rig’s electro-hydraulic systems. With this added time saving functionality the piling crew can tackle the pre-auger works in relatively short runs at a time, switching between auger works and vibrator works more frequently without any real loss of production time. This approach has considerable advantages over simply pre-augering the entire pile line in one go: · Firstly, the pre-augered hole positions will better match the actual interlock spacings of the sheet pile pairs as this dimension tends to increase/decrease a little from theoretical as each pile pair is installed into the ground; in fact pre-augering too much of the pile line in one go can actually hinder the installation process rather than aiding it because the drilled positions and interlock spacings become misaligned as pile installation progresses. · Secondly, in certain ground conditions the soil in the pre-augered holes can reconsolidate when subjected to ground transmitted vibrations. Drilling too far ahead of the installed pile line can therefore become wasted effort. The TM20 Mobilram was required to work in a very narrow corridor alongside the M25 which necessitated more tracking movement and careful slewing control. Despite these constraints the rig achieved excellent pile production and installation quality as can been seen in these pictures. This Mobilram was built with all the very latest technology on-board including ABI’s unique Efficiency Drive System which delivered significant reductions in both fuel consumption and exhaust emissions. Excellent news for Ivor King, his client, and the planet! #sheetpiling #pilingrig #motorwaywork #M25 #Mobilram
