    Tremie concrete refers to placement by gravity feed from a hopper through a vertical pipe extending for above the surface to the underwater floor As concrete flows from the bottom of the pipe, more is added to the hopper so that the tremie pipe is continuously charged with fresh mix The major aim in underwater concreting is to place the mixThe construction starts by drilling a vertical hole into the soil using the bored piling machine The machine is outfitted with accessories like drilling tools, buckets, and grabs that help remove soil and rocks during the drilling process The piles drilled can go up to a depth of 60 m and a diameter of 24 mHow to Construct a Bored Pile Foundation?
