1, The diversion tunnel section excavated by tunneller is buried deeply, the under ground water level is high, the activities of underground water is lively, and Karst topography is quite developed.

2, Diagnosis of common faults and remove ways about walking part to tunneller are introduced.

3, The results can be used as reference for the improvement of tunneller and for the design of new machine.

4, If the monitor Web Service box was checked during the WSDL-to-Java generation, the SOAP invocation request should appear in the TCP/IP tunneller with an empty SOAP response (see Figure 23).

5, Structures, cutting mechanism and stress wave theory of the tunneller a re presented and analyzed.

6, The paper analyses the hydraulic system of the walking mechanism of AM-65 tunneller and discusses its working features.

7, This paper introduces the main technical parameters, structures and technical features of EBJ-120TP type tunneller.
