Diesel is usually used, but other compression ignition engine fuels can also be used.

Diesel hammer is a kind of construction machinery, which is commonly used in construction

Diesel hammer is to use fuel explosion to push piston reciprocating motion and hammer pile driving, piston weight from hundreds of kg to several tons.

The pile should be driven with heavy hammer and light hammer. If the heavy hammer hammers hard, most of the hammering work is absorbed by the pile body, the pile is not easy to drive, and the pile head is easy to be broken. There should be a certain ratio between the hammer weight and the pile weight, or the hammering stress should be controlled to prevent the pile from being damaged.

Pile frame is a kind of pile driving equipment which supports the pile body and pile hammer, guides the direction of pile in the process of pile sinking, and enables the pile hammer to impact along the required direction.

Operation experience of diesel hammer pile driver

The installation area of diesel hammer pile driver should be selected in the area without high voltage cable to avoid accidents.

First of all, when using the diesel hammer pile driver, it is necessary to use a fence and set up obvious signs to prevent the entry of irrelevant personnel. In the process of pile hammer construction, the operator of diesel hammer pile driver must stay outside the scope of five meters of pile hammer for exploration and protection.

Second, the survey machine, especially in the investigation of the pilot plate, should be careful to avoid any damage to the bolts of the hammer.

Third, before operating the diesel hammer pile driver, the fuel oil with the specified proportion should be used. The fuel tank should be filled, the oil outlet valve and vent plug should be opened, the internal air should be drained, the oil injection in the cleaning hole should be investigated, and appropriate adjustment should be made.

Fourth, before using the oil plug in the oil storage chamber of the diesel hammer pile driver, fill up the lubricating oil according to the regulations, open the special oil pump to add lubricating oil to the lubricating oil pipeline of the pile hammer, and empty the air in the pipeline.

Fifthly, when the pile hammer of the diesel hammer pile driver is separated from the anvil, if the falling length is more than 200 mm, and the contact area between the anvil and the rubber pad is less than two thirds, the rubber pad should be replaced.
