Prefabricated utility
tunnel construction causes minimal damage to the construction site with high
efficiency, and is economically beneficial when applying large-scale construction. In this study, the authors investigate the
current development status of the prefabricated utility tunnel construction
equipment in China, and elaborates on four types of mechanized construction
equipment suitable for prefabricated assembly methods, i.e., gallery crane,
rectangular pipe jacking machine, U-shaped shield, and
U-shield pipe jacking machine. The basic configuration,
working principle, efficacy analysis, and engineering application of these four
types of equipment are presented. The research results show the following: (1)
Compared with conventional cast-in-place construction, prefabricated assembly technology applied in the
utility tunnels is convenient and fast, which can effectively shorten the
construction period, reduce labor costs, improve the pouring quality of
components, minimize the impact on the surrounding environment, and achieve
"green construction". (2) The U-shield pipe
jacking machine integrates the characteristics of small earthwork excavation
volume, high mechanization efficiency, and strong construction adaptability,
which can meet the needs of future utility tunnel construction and provide a
new direction for the development of prefabricated utility tunnel construction
equipment.
