Pipe jacking method introducing slurry pipe jack up procedure is developed to improve economy as well as to accomplish reliably execution result and to reduce adverse effect to the surrounding environment in shield tunnel boring works for laying supply water pipe, electrical or gas piping or communication network lines. This machine employed in this method is applicable to a variety of soil property raning from rock or boulder layer to normal soil. It accomplishes long distance thrust (300`700mm for 1span) and enables replacement of cutter bit at anytime as required.
Features
1. Drive system in DH-L, installed on the periphery of the machine, generates
high torque, With attached high-power cone crusher in a chamber, it is
adaptable to large boulder layer as large as 2/3 of the nominal diameter
to 200MPa rock layer. 2. Cutter bit, when worn out, can be replaced from
inside of the machine. 3. Optimum cutter selected in accordance with the
soil property will offer effective excavating capacity and reduces surface
resistance. 4. High precise excavation result can be obtained not only
for linear excavation but for curved excavation with its effective center-bending
method steering mechanism, thrust angle sensor and detective system using
optical instrument.
