This kind of construction machinery is common for construction site
Diesel engine hammer is to use gasoline and diesel explosion to promote the linear movement of piston rod and hammer the foundation pile. The net weight of piston rod is from hundreds of kg to several tons.
The pile should be driven with heavy hammer and light hammer. If the heavy hammer is used to strike hard, most of the hammering power is absorbed by the pile body, and the pile head is easy to be smashed. There should be a necessary ratio between hammer weight and pile weight, or the ground stress of hammering should be controlled. The manufacturer of hydraulic impact hammer should prevent the pile from being broken.
Hydraulic hammers belong to percussive foundation piling hammers, which can be divided into single effect type and double effect type according to their structure and principle. In brief, the single effect type refers to that the impact hammer core is released rapidly after the hydraulic device is raised to the predetermined height width ratio, and the impact hammer core severely strikes the pile by free falling method; the double effect type refers to that the impact hammer core obtains instantaneous velocity kinetic energy from the hydraulic transmission system to increase the impact speed and severely hit the pile body after the hydraulic device is increased to the predetermined height width ratio. This also matches the two basic pile foundation theories. The single effect hydraulic press foundation pile hammer matches the heavy hammer light driving foundation theory. It is characterized by large hammer core net weight, low impact speed and long hammering efficiency time. The pile hammer has a large penetration per blow, and is integrated into various types of piles with various shapes and materials. The damage rate of pile is low, especially when it is suitable to drive concrete pipe pile. The theory of double effect hydraulic press foundation pile hammer matching light hammer heavy driving foundation is characterized by smaller hammer core net weight, higher impact speed and shorter hammer effect time. It has large impact kinetic energy and is more suitable for driving steel pile.
Hydraulic breaking hammer is generally called "crushing hammer" or "crusher". The driving force of hydraulic breaking hammer is the working pressure shown by excavators, small forklifts or sewage treatment plants. It can crush pebbles and rock strata more reasonably and improve efficiency in construction. The standard of using hydraulic breaking hammer is to select the more suitable hydraulic crushing hammer according to the excavator model and the working natural environment.
