Concrete Pumping
Amongst the various equipment's now available, concrete pumps are most versatile as compared to other placing equipment. This publication deals at length with the concrete pumping method for placing concrete.
CONCRETE PUMPS
Generally concrete pumps are either mounted on a truck or on a trailer . The pumps are either diesel or electrically operated. The concrete is
pumped through the pipeline of diameter between 100 mm to 180 mm. The most popular and suitable diameter for normal pumping is 125 mm.
Modern portable concrete pumps now manufactured in the overseas countries are in their fifth generation having enormous power, high capacity and absolutely reliability hydraulic system. They can pump concrete to a height of nearly 500 M or cover horizontal distance upto 2000 M. The p-umps have hydraulic system which ·an take concrete pressures upto 200 bars. The pumps' outputs range from 19 to 150 CuM per hour. Different manufacturers have developed different types of valves or systems. The rock valve , 'C' valve system , flat gate valve and 'S' trunk system are generally adopted depending on the customer's choice, and use or the manufacturer's patented system. However it may be noted that the a rock valve system got its name in Germany. In German language rock mens a woman's skirt and since the valve has a similar shape and movement it is called so.
Pumps are generally designed with adequate protection against adverse usage, they are insensitive to rough treatment and operation on construction sites, have sturdy construction and are easy to maintain. The gate valves cut through concrete and are fully lined with highly wear resistant metal and can be quickly replaced if it is worn out. Rams are of special vulcanized rubber, lined with steel core, and are easy to replace as they have quick detachable connectors. The metal core is fully encased to avoid concrete adhesion.
