Abstract

The invention discloses a piling device and method. The piling device comprises a pile hammer, pile hammer coils, a pile body, pile body coils and a supporting mechanism. The supporting mechanism provides support for the pile hammer and the pile body, so that the pile hammer and the pile body freely move on the supporting mechanism; the pile hammer coils are fixed to the pile hammer; the pile bodycoils make contact with the pile body; the pile body coils and the pile hammer coils are coaxially arranged; and preset distances are reserved between the pile body coils and the pile hammer coils soas to guarantee that electromagnetic force between the pile body coils and the pile hammer coils meets the requirement. The piling device which is simple in structure, convenient to operate, fast inoperation, adjustable in impact force, high in efficiency, small in energy consumption, safe, reliable, free of pollution and suitable for different soil is provided for pile foundation construction.

Description

technical field [0001] The invention belongs to the field of pile foundation construction, and more specifically relates to a piling device and a piling method. Background technique [0002] The hammering pile sinking method mainly overcomes the resistance of the soil to the pile through the impact generated by the falling of the pile hammer, thereby driving the pile into the foundation. Commonly used pile hammers include: diesel hammer and hydraulic hammer. The diesel hammer drives the piston to reciprocate through the fuel explosion to hammer the piling. Its mechanical structure is simple, but the energy transfer rate is low, the reliability of the device is poor, and the maintenance and repair are frequent. At the same time, it is difficult to accurately adjust and control the piling force. It is easy to cause serious environmental pollution, and the working conditions of operators are very bad. The hydraulic hammer mainly drives the impact part through the oil cylinder...
