Safety requirements for diesel hammer pile drivers for diesel hammer pile drivers
19, the operation should always check whether the fasteners are loose, the moving parts are flexible. Diesel pile hammer after the operation note 20 after the operation, diesel hammer should be parked in a solid flat ground, diesel hammer should be placed on the ground plate or into underground pile, shutting down the fuel switch, barrel type hammer should be put in the net cooling water, mounted on the cylinder head, exhaust cover, safety screw etc., and mounted on the safety card. The pile holder shall be placed in a stop position, locking the safe and braking position. 21 rail type pile holder should clamp the rail clamp when it is not working. When the 22 pile stand is broken, the brake performance of the hoister shall be checked first, and then operated according to the procedures specified in the instruction manual. 23, long-term disabled, should be unloaded diesel hammer, loaded with safety board, the diesel hammer fuel, lubricating oil and cooling water all out, cleaning the combustion chamber, coated with anti rust oil on the ball bowl, and take rainproof measures.
11 water cooled diesel hammers shall be maintained with sufficient cooling water for continuous work and shall not be used without water. 12 operation, diesel hammer final ten hit penetration should comply with the provisions of the use manual, when every ten hit penetration is less than 20mm, should stop hammering or replace pile hammer. 13 during the piling process, lubrication and repair shall not be performed. 14 when the hammer (pile) of pile driver is used, the minimum distance of hammer (pile) from the top of column shall be ensured. 15 after the pile is inserted, the verticality of the pile should be corrected in time. When the pile is embedded in the 3M, the pile should not be taken for walking or turning to correct it. The 16 batter pile, the vertical pile should be vertical, the pile into fixed, and then began to tilt, tilt 18.5 degrees in the post, should not raise diesel hammer. Track three fulcrum type pile frame in the backward of batter pile, should use the rear leg cylinder; track type pile frame should be increased after the support platform, and clamping rail clamp. 17 when driving, the diesel hammer shall be lowered to the lowest position, and the slope shall be in accordance with the instruction manual. Self propelled pile drivers should be manned by hand. When walking on the ramp, the center of gravity should be moved to the top of the ramp. The distance from the pipe type piling machine to the end of the roller tube shall not be less than 1m. 18 during operation, the slewing brake should be slow, and the track type and walking type pile stand shall be turned in the same direction, not more than one week.
1, the pile driver walking and slewing, hanging pile, hammer should not be carried out simultaneously. The pile driver shall not turn or walk in full swing after hanging the pile. 2 Side Piling and long distance pulling pile are not allowed in pile driver. When the pile is hoisted in front, the horizontal distance of concrete shall not be greater than 4m, and the steel pile shall not be larger than 7m, and the pile shall be prevented from colliding with the post. 3 when the column is turned into place and the column is locked, the piling frame of the double guiding post can be operated. 4 before the start of the diesel hammer, the pile hammer, the pile cap and the pile should be on the same axis, and shall not be driven by eccentric piling. 5 in soft soil pile driving, should first close the throttle, cold beat, to each attack penetration is less than 100mm, can start the pile hammer. 6 after the start of the diesel hammer, the landing gear should be lifted. The distance between the landing gear and the top of the cylinder of the cylinder hammer shall not be less than 2m during the hammering process. 7 when the diesel hammer is running, the jumping height of the impact part shall be visually observed, and the requirements of the instruction manual shall be strictly enforced. When the required height is reached, the throttle shall be reduced and the stroke of the impact part shall be controlled. 8 during the operation, attention should be paid to the change of the soil layer and the operation of the pile driver, and the necessary measures should be taken in time. 9 diesel hammer appear early ignition, should stop working, according to the instructions for processing. 10 when the piston jumps on the cylinder hammer, the grease should be observed to flow out of the drain hole. The lubricating oil of the lower piston shall be filled according to the instruction manual.
