Design and research of smart construction equipment for precast segmental urban utility tunnels
More and more precast utility tunnels with large cross-sections and complicated structural styles have been built with the blowout growth of utility tunnels in China and its vigorous advocacy of "green building". The precast segmental construction technology of underground utility tunnels has incomparable advantages compared with conventional utility tunnels. This paper introduces a piece of smart construction equipment for precast tunnels which mainly includes five main structures - excavation and support cabin, segment assembly cabin, backfill support cabin, roof platform, and gantry crane, seven systems - thrusting system, articulated steering system, clamping system, grouting system, articulated sealing system, tail sealing system and monitoring system and other supporting systems. The finite element models of excavation and support and segment assembly cabins are established. It is verified that no part of the equipment exceeds the yield strength of Q345 and that the stress and strain are within the allowable range. This paper provides a reference for the smart construction of urban underground utility tunnels.
