What is the construction procedure of bored cast-in-situ concrete pile using rotary rigs?
Shift and set the rig at the location of pile alredy surveyed. complete the boring to the required depth by attaching the boring assemblies with the rig. Flush the bore hole with bentonite solution. remove the boring assembly and insert the pre fabricated reinforcement cage. laping should be welded. set the reqiured length of tremmi pipe (dia not less than 200mm) and do flushing with new bentonite solution having density not more than 1.12. continue the flushing for atleast 30 minutes and check the density of liquid over flowing from the bore hole. if the density of it is 1.12 stop the flushing and pore the concrete stage by stage upto the cut off level.
thank you

How do you mix and batch concrete by a small rotary mixer?
To mix and batch concrete using a small rotary mixer, begin by measuring the appropriate amounts of dry ingredients: cement, sand, gravel, and water, typically following a mix ratio like 1:2:3 for cement:sand:gravel. Add the dry ingredients to the mixer first, then gradually add water while the mixer is running to achieve a consistent, workable consistency. Allow the mixer to run for about 3-5 minutes to ensure thorough mixing. Once the concrete reaches the desired uniformity, pour it out for use.

What is a rotary union?
A rotary union / rotary joint is a mechanism used to transfer liquids and/or gases while rotating or swiveling from one connection to another. Rotary unions are engineered to endure a large range of temperature and pressure for a variety of conditions and environments. In addition, rotary unions may integrate multiple ports and handle different types of media concurrently.Rotary unions function by connecting to an input and securing onto another mechanism while allowing a moving connection to be preserved. They are utilized in a variety of applications; from miniature rotary unions for the semiconductor industry to large, heavy-duty rotary unions for industrial applications. Additionally, numerous materials, seals, and bearing types can be incorporated.Reference - .dsti.com/products/rotary-union

What is rotary pile?
A rotary pile is a type of deep foundation used to support structures by transferring loads to deeper, more stable soil or rock layers. It is constructed by drilling a hole into the ground and then filling it with concrete or other materials, often reinforced with steel. The rotary method involves using a rotating drill bit to create the hole, allowing for precise control and effective excavation in various soil conditions. This technique is commonly employed in construction projects requiring strong foundational support, such as high-rise buildings and bridges.
