Hydraulic Hammer Impact Energy

Hydraulic hammer belongs to 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 is also corresponding to the two piling theory, single-acting hydraulic piling 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 per click Penetration, 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 piling 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.

Due to the engineering geology, various pile bases have been applied in Guangdong. Among them, prestressed concrete pipe piles are a kind of new type of pile, which has the advantages of low cost, reliable quality and fast construction speed. Prestressed concrete pipe piles have been widely used in Guangdong, prestressed concrete pipe pile piling equipment has also been developed, advanced imported piling equipment and distinctive domestic piling equipment are in the prestressed concrete pipe pile construction An important role in promoting the pomp market to flourish. This article will introduce a foreign has been widely used in advanced piling equipment - hydraulic piling hammer development and application.

In Europe in the 1970s, with the development of urban modernization and the gradual improvement of environmental regulations, the diesel piling hammer, which was the main piling market, was gradually banned because of its own structural problems that can not be solved, namely noise, vibration and fume pollution use. And because of the heat 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 piling hammer is developed in this situation.

As a century-old basic engineering equipment manufacturing and construction company, the British BSP company as early as 1972, the first to develop the first hydraulic piling hammer. After seven years of testing and improvement, hydraulic piling hammer manufacturing and construction technology has gradually been mature.

Hydraulic piling hammer due to piling high efficiency, low noise, small vibration, no smoke pollution, its advanced nature has been widely recognized. Today, in Western developed countries and Asia, Japan, South Korea, Hong Kong and Singapore and other countries and regions, hydraulic piling 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 piling hammer instead of diesel piling hammer in the inevitable, which is the national industrial level and the degree of civilization symbol.
