Abstract: In allusion to the situation of trenchless pipe laying increase steadily in buried pipeline construction, performance of trenchless equipment and technical characteristics are introduced, and advantages of machinery pipe pushing technology and its development and application at home and abroad are given.Basic work principle of pipe pushing operation is described, and mud-water balance tunneler and soil-pressure tunneler commonly used in construction of city pipeline networks, construction process and main constitution and functions of the construction equipments are emphatically introduced.Through analyzing performances and characteristics of multi-blade disc soil-pressure balance tunneler, single-blade soil-pressure tunneler, adjustable blade mud-water balance tunneler and eccentric crushing mud-water balance tunneler used at different geological conditions, methods to select pipe pushing equipment are given.
