Method Statement - DMC Piling:
For executing DMC piles (Direct Mud Circulation piles) method which is approved as per IS 2911 and British Standards under specifications of bored cast in situ piles. The bore holes will be advanced by chisels weighing above 1000kg by circulating betonies slurry using a 20 HP vertical motor and pump. Because of the impact of chisel the cuttings will be brought out by the betonies slurry and the bore holes will be advanced to the founding strata which is about 15 to 20 meter in depth.
The founding strata can be rock or dense sand having N value > 50 as per structural design. To prevent the side collapse and caving in, a guide casing of 500 -1500 mm dia and 1 to 1.5M depth will be fixed on the top of the bore hole and this will be withdrawn after concreting is over. Once the bore hole reaches the final depth the chissel will be kept for about 15 minutes to clear out all the cuttings from the bore hole. After this the chissel will be removed from the bore hole and steel cages will be inserted in to the bore as per the structural design and tremmie pipe of 8 inch dia meter will be inserted to the center of the cage.
After the insertion of tremmie pipe, the bore will be thoroughly cleared by using betonies slurry pumped through a 20 HP pump. Once the bore is clear ready mix concrete of required specification will be poured through the funnel fitted on the top of the tremmie pipe and the concrete will be made to overflow from the bore till all the laitance is removed from the bore and good concrete appears on the top. The theoretical volume and actual concrete used will be measured and recorded including details of reinforcement etc. on a bore long which forms the basis of measurement between the contractor and client.
