Under beaded piles are cast concrete piles in situ that have one or more numbers of bulbs formed by enlarging the stem of the pile. These piles are more suitable in soils where there are considerable movements in the soil due to seasonal variations, in full soil or in soft soils. The provision of flush bulbs has the advantage of increasing load and lifting capacities. It also provides better anchorage at greater depths. These batteries are used efficiently in the foundations of the machine, on the bridges, the electric transmission tower the foundation of sand water tanks. The Indian Standard IS 2911 (Part III) - 1980 covers the design and construction of reamed batteries with one or more light bulbs. According to the code, the diameter of the flanged bulbs can vary from 2 to 3 times the stem diameter depending on the feasibility of the building and design requirements. The code suggests a spacing of 1.25 to 1.5 times the diameter of the bulb for the bulbs. An angle of 45 ° with horizontal is recommended for all bulbs with flanges. This code also gives mathematical expressions for calculating support and elevation capabilities.
