Bored pile is type of reinforced concrete pile which is used to support high building which has heavy vertical load. Bored pile is a cast-in-place concrete pile where the bored piles have to be cast on construction site. Bored piling is cast by using bored piling machine which has specially designed drilling tools, buckets and grabs, it’s used to remove the soil and rock. Normally it can drill into 50metres depth of soil. The advantage of bored piling is its’ drilling method, little vibration and lower noise level. Bored piling is popular to be used in construction as a foundation especially for bridgework and tall building as well. Also bored piles are able to penetrate moderately hard bedrock materials more easily than other methods. They are unsuitable where the ground water level on the retained side is high.
Tractor Mounted Rotary Rig:
this type of method is very fast and requires the tractor mounted rig which is available with us. The method involves aucher boring into the ground according to the depth of the pile and the aucher rimmer varies in size according to the diameter of the pile. the required depth including the hard strata is achieved by drilling in the ground by adding dmc rods inside the hole for the required depth and by flushing the bentonite water through a whose pipe valve from the bentonite tank that is set up already with a drainage line to the tank
Once the boring is completed the fabricated steel reinforcement is erected inside the hole and the concrete is poured inside the bore hole. the pouring is continued until the overflow of concrete is achieved.once it is done the temporary casing is removed and the process is finished.
