The principle of pile driver
(3) vibration hammer. Using the mechanical vibration force of the pile hammer to make the pile sink into the ground, it is suitable for carrying less precast concrete pile, steel sheet pile and so on.(4) static pile pressing machine. Produced by mechanical hoist or the pressure of the hydraulic system, the pile in the hydrostatic pressure under the action of pressure in the soil, various types of precast pile used in general bearing capacity.
Types of pile drivers:(1) steam hammer piling machine. High pressure steam will be used to lift the hammer head, and then hit the pile head against the weight of the hammer, so that the pile will sink to the ground.(2) diesel pile hammer. Use the fuel explosion to push the piston and impact the pile head by explosive force, so that the pile will sink into the ground and be suitable for all kinds of precast piles.
The principle of a pile driver is the use of impact force to pile into the formation of the pile machinery.Construction of piling machine is composed of pile hammer, pile frame and ancillary equipment etc.. The pile hammer is attached to two parallel vertical guide rods (commonly called Longmen) at the front of the pile support and hoisted with lifting hooks. The pile foundation is a steel structure tower with a windlass at the back of which is used to lift the pile and hammer. A guide frame consisting of two guide rods is used in front of the pile to control the direction of the pile driving so that the pile can be accurately penetrated into the formation in accordance with the design orientation. The tower and the guide frame can be used to batter pile deflection. The guide frame can also be extended downward along the tower and used to fetch water along the embankment or pier. The pile can move and move. The basic technical parameters of a pile driver are impact weight, impact kinetic energy and impact frequency. According to the motion of the pile hammer power source can be divided into hammer, hammer, diesel hammer, hydraulic hammer etc..Piling machine type: piling machine and rotary drilling pile machine, with spiral to the underground digging, then pouring pile.
