(1) There should be no high voltage line in the piling machine work area. The work area shall be marked or fenced, and non staff members are not allowed to enter. During the whole driving process of pile hammer, the actual operation staff must monitor the distance of 5m away from the pile hammer management center.
(2) Diesel engine foundation pile hammer shall use gasoline and diesel oil with required mortar mix proportion. Before working, the diesel oil tank shall be filled and the oil outlet valve shall be opened.
(3) Before working, the opening gas plug should be opened to drain the gas in the fuel pipe. The high-pressure oil pump should be checked regularly, and the condition of the oil pump should be observed from the cleaning hole. If any abnormality is found, it should be adjusted.
(4) Before operation, the upper piston rod should be lifted slightly higher than the upper cylinder with landing gear, and the oil plug in the oil storage chamber should be opened, and the grease should be filled up according to the regulations. For the fully automatic moistening pile hammer, special gasoline pump should be selected to add grease to the grease pipeline, and the gas in the pipeline should be removed.
(5) For the newly opened pile hammer, 0.6L lubricating grease shall be poured along the upper piston rod for ten days in advance, and the manufacturer of diesel pile hammer shall fill the lower piston rod with sufficient grease with oil gun.
(6) Check that all the anchor bolts are tightened, and check the fixed anchor bolts of the guide plate as the top priority. Do not work under the condition of looseness and missing parts.
(7) The contact line between the starting hook and the upper piston rod is between 5 and 10 mm.
(8) When it comes to the pile hammer slipping off the anvil, its falling length is not suitable to exceed 150 mm. When exceeding, adjust the rope buckle of pile cap.
(9) Check the damaged gap of the guide plate. When the gap exceeds 7mm, it should be replaced.
(10) The rubber cushion should be checked. When the surface of anvil and rubber plate is less than 2 / 3 of the original total area, or the gap between the lower cylinder flange and anvil is less than 7mm, the rubber plate should be removed and replaced.
(12) For the water-cooled pile hammer, the water in the water storage tank should be filled with oil. Softened water must be used for cooling circulating water. The water needs to be warmed up in winter.
(12) Before starting the pile hammer, the pile hammer, pile cap and pile shall be on the same center line, and axial force foundation piling is not allowed.
(12) When starting the pile hammer in the soft soil layer with large pile penetration, the accelerator pedal shall be turned off for cold driving, and the accelerator pedal shall be opened to start the pile hammer when the penetration is less than 150 mm.
(14) After the pile is inserted, the flatness of the pile shall be corrected immediately. When the pile is buried about 3M, it is forbidden to use the pile driver to correct the slope of the pile.
(15) In hammering, the upper piston rod is larger, and the ratio of height to width does not exceed the requirements of the original manufacturer's instructions. The measured aspect ratio should be in accordance with the estimation table or calculation method in the original manufacturer's instructions. When the required aspect ratio is exceeded, the accelerator pedal should be lowered to control the drop distance.
(18) When the piston rod falls and the diesel engine hammer does not deflagration, the upper piston rod may fluctuate in a short period of time. At this time, the landing gear cannot fall down and collision block should be prevented.
(18) During the whole process of foundation piling, full-time personnel should be responsible for pulling the control rope on the crank arm; in case of accident, the control rope can be used to stop the hammer.
(16) After the piston rod and the starting hook are separated, the landing gear should be lifted again, and the distance between it and the upper cylinder should be more than or more than 2m.
(21) during operation, the most important thing is to check whether the grease on the piston rod is leaking from the oil inlet. When the oil pump is fully lubricated, check whether there is automatic lubrication when the pump is fully lubricated. When the driving time of a pile exceeds 15min, grease shall be filled immediately after driving.
(20) When the impact kinetic energy of pile hammer exceeds the larger kinetic energy, the penetration value of the final 10 hammers should not be less than 5mm.
(21) the filling material in the pile cap shall not be inclined, and the management center of pile cap shall be hammered during the work
(26) when the water in the water jacket is less than the suction port of the lower cylinder due to volatilization, it should be filled immediately and no water is allowed to work.
(21) in case of extreme weather such as rainstorm, hail and strong wind of level 6 or so, any work shall be terminated. When the wind speed exceeds level 7, there must be a hurricane alarm, the pile driver should be stopped along the wind direction, and the cable wind rope should be lifted.
（24） After shutdown, the pile hammer should be put into a small part, the cylinder head and the suction and exhaust hole bottle plug should be covered, the fuel valve should be closed, the actual operating lever should be placed at the shutdown position, the landing gear should be raised to the place LM higher than the pile hammer, and the safety limit switch equipment should be locked.
(20) The pile hammers that have been out of service for a long time should be removed from the pile driver, and the cooling circulating water, gasoline and diesel oil and lubricating grease should be drained. The striking surfaces of the combustion chamber and the upper and lower piston rods should be cleaned up. The anti-corrosion measures should be taken, and the mobile phone cover should be covered and stored in the warehouse.
