With the construction case of 65m long pipe-shed pre-reinforcement,the paper introduced the construction technology of long pipeshed with Haiwangxing-508 drilling machine,and discussed the feature requirement of drilling machine in the construction.

The application of lead pipe-shed support in tunnel construction;

Taking the construction practice of pedestrian inclined shaft passing through the quicksand bed in Xiyu Coal Mine, Taiyuan City, as the example, this paper expounds the principles of lead pipe-shield pre-support, the design of pipe-shield support, the construction technology, and the forms of secondary support, etc.

According to the practical engineering characteristics of Xizhigou 1# tunnel,the pipeline shed advance timbering technology is adopted.
