The CONCRETE Times • SUMMER 15 CAMFAUD IN LONG BOOM UXBRIDGE POUR TWO PUTZMESITER BSF 16H HIGH VOLUME PUMPS USED BY CAMFAUD IN 450 M3 POUR World leading Planetary, Twinshaft & Pan mixers from Italy Large UK spares warehouse Sam Willis, Sales Director sam.willis@sicomaomg.co.uk 16 www.sicomaomg.co.uk 01524 762 762 Camfaud Concrete Pumps have recently completed a large slab pour for McDermott Building & Civil Engineering with the pumps chosen for the pour being both high volume Putzmeister BSF16H pumps capable of pumping 160 cubic metres of concrete per hour. The booms used were an M52 and an M47 i.e 52 metre and 47 metre reach respectively. The high output models were chosen to ensure that the concrete was comfortably placed within a standard working day so neighbours would not be disturbed by early or late working noise. The large booms were selected to ensure that all of the concrete could be placed “off the boom” with no requirement for ground lines. This way of working is obviously much faster but it is also much safer as there is no requirement for the concreting gang to move the pipes around the site, the placing booms do all the heavy lifting. To further enhance the safety features of the booms, they were fitted with pneumatic end hose valves. These valves are closed prior to moving the booms to ensure that concrete does not fall from the boom under gravity, spoiling the finished work and causing potential injury. The slab was calculated at 450 cubic metres in total, and with a local batching plant and 6 truck mixers dedicated to the pour with concrete supplier, London Concrete, holding contingency stocks of cement and aggregates, supply kept pace with the pumps and the pour was completed, on schedule, in the mid-afternoon, coming in at almost exactly the calculated volume. The experienced Camfaud pump operators, observed that the largest pours are often the most straightforward. “Everyone involved gears up for the big pours as they are critical to the progress of the job. “The contractor prepares a large, solid pad for us to set up on, the ready-mixed companies ensure mixer truck availability to keep up with the pour rate and the concreting gang floods the pour with men to cope with the volume of concrete and to deal with the odd snag that can arise.” The pour in full swing INDUSTRY NEWS
