Hydraulic Hammer Development And Use History
The development and use of Hydraulic Hammer history
In the 1970s in Europe, with the development of urban modernization and the gradual improvement of environmental laws and regulations, once the piling market, the main diesel piling hammer due to its own structure can not solve the problem that noise, vibration and smoke pollution problems and gradually prohibited use. And because of the thermal volume and efficiency constraints, theoretically the largest diesel hammer impact hammer core quality can only reach 15 tons, can not meet the requirements of large prefabricated pile construction. In order to seek alternative upgrading of diesel piling hammer, countries are studying new piling equipment and construction technology, Hydraulic Hammer is developed in this situation.
As a historic infrastructure equipment manufacturing and construction company, our company as early as 1972, the first to develop the first Hydraulic Hammer. After seven years of testing and improvement, Hydraulic Hammer manufacturing and construction technology has gradually been mature.
Hydraulic Hammer due to piling high efficiency, low noise, vibration, no smoke pollution, its advanced nature has been widely recognized. Now in Western developed countries and Asia, Japan, South Korea, Hong Kong and Singapore and other countries and regions, Hydraulic Hammer has completely replaced the diesel piling hammer, piling the market has become the absolute main force. With the progress of social civilization and economic development, with Hydraulic Hammer instead of diesel piling hammer in the inevitable, which is the national industrial level and the degree of civilization symbol.
The basic principle and construction of Hydraulic Hammer
Hydraulic Hammer is impact piling hammer, according to its structure and working principle can be divided into single acting and double acting two. The single acting type refers to the impact of the hammer core through the hydraulic device to a predetermined height after the rapid release of the impact of the hammer to the free way to fight the pile; double action refers to the impact of the hammer through the hydraulic device to a predetermined height, from the hydraulic The system gains acceleration energy to increase the impact speed against the pile. This also corresponds to the two piling theory, single-acting Hydraulic Hammer corresponding to heavy hammer tapping theory, with a larger weight of the hammer, lower impact speed, longer hammer action time is characterized by pile hammer every hits Into the large, to adapt to a variety of shapes and materials pile type, loss of pile rate is low, especially suitable for playing concrete pipe pile. Double acting Hydraulic Hammer corresponding to the theory of hammer weight, with a smaller weight of the hammer, the higher the impact speed, shorter hammer pile action time is characterized by the impact of energy, the most suitable for playing steel piles.
