Construction equipment and method of breaking pile head with hydraulic pile driver.Now China's high-speed rail full construction, pile foundation is naturally high-tech content of the railway technology is an important part of the essential. After the construction of high-speed railways such as Wuhan-Guangzhou, Zhengxi, Harbin, Beijing, Shanghai and Shiwu, the state has put forward higher and higher requirements for high-speed rail construction technology. At the same time, domestic labor costs have increased sharply in recent years. The construction machinery used in the requirements of the equipment has gradually increased, a variety of advanced construction equipment have entered the field of high-speed rail construction.

Hydraulic pile driver is currently the world's most advanced equipment to break the pile head, which uses a number of hydraulic cylinders squeeze the pile, from the same end of the same point at the same time squeeze, cut off the working principle of the pile head, simple, efficient and environmentally friendly The Hydraulic pile driver mainly consists of power source and working device composed of two parts, the working device by a number of the same type of hydraulic cylinder combined into different diameter crusher to meet the various types of pile pile pile requirements.

The piston of this cylinder is made of alloy steel, which can meet the requirements of the broken concrete of various labels.

Power source can be fixed pump station or other mobile engineering machinery and equipment, under normal circumstances, in the construction of high-rise building pile foundation in the use of more pumping stations, this combination of equipment, the overall investment is relatively small, but the move is not Very convenient, suitable for group pile pile head in the break.

In the construction of the bridge using a convenient excavator as a power source more (as shown), the excavator bucket removed, in the bucket and arm connection axis hanging pile driver chain, The two devices are mechanically combined and then the hydraulic circuit of any one of the excavators is connected to the cylinder of the pile driver through a balancing valve to drive the cylinder block of the pile driver. This combination of pile driver easy to move, the operating surface is relatively wide, for the pile is not concentrated, long work long construction projects, but the investment is relatively large.
