Development of New Jacking-pulling Rectangular Driving Machine and the Application

Abstract:

A new rectangular driving machine is introduced about its design method and its main technical parameters, which is suitable for micro working well with jacking-pulling construction technology. Combining the pulling force of driving system with the driving machine, deflection and backward of the machine head are solved in common rectangular pipe jacking construction. The machine head is designed with multi-cutter, each cutter is positive inversion and rotary speed can be easily adjusted with less machine head deflecting. The new driving machine can also be operated only with jacking force.
