DJM restructuring high pressure jet grouting machine shotcrete upgrade: When under the nozzle into the design depth, should be carried out in situ static spray shotcrete, cement slurry to be returned to the aperture normal only after the start of the jet grouting to enhance piling Construction Code Assignment: 1, is not fully reliable and placed before the completion of the preparations are not allowed to start the diesel hammer pile driver self-drilling rotating jet, diesel hammer 2015 should ensure that no foreign matter inside the new rotary jet pile driver, to prevent accidents. 2, jet grouting pile next piston downward projecting price parameters model, are not allowed to start the diesel hammer to prevent damage to the connection flange and the lower cylinder. 3, diesel hammer pile frame rails or parked out on the skids, are not allowed to start the diesel hammer. 4, should take measures to prevent playing eccentric pile, if found during construction must be corrected immediately. 5, if the Pistons hit 10 times each, the total pile sinking (ie Penetration) is less than 20mm, it must stop immediately, otherwise it can easily cause fatigue fracture under the piston. 6, if the penetration of the pile becomes smaller jet grouting pile, should be checked on the piston rebound is too high, and regulating every diesel hammer blow energy or parking. 7, always check the diesel hammer guide plate, landing gear attachment bolts guide block, according to the provisions of twisting torque requirements tighten. Diesel hammer guide plate, the guide portion of the landing gear guide block wear or deformation must be replaced immediately. 8 Do not use rail deformation or excessive wear of the pile frame, in order to avoid accidents. 9, piling operations must strictly abide by the "diesel hammer Manual" specified tilt range. 10, diesel pile hammer or signs of damage or damaged, you must immediately stop.
