Case study of a synchronous hydraulic jack-up system for constructing high-rise residential buildings

초록

In recent years, contractors have frequently needed to apply innovative technologies to fulfil architects' creative and intricate designs. They have often encountered abnormal construction conditions. One of the challenging and difficult process is the lifting of a heavy structure called the sky transfer truss (STT). especially if undertaking such a lift is not prevalently experienced. This can result in hazards, accidents, schedule delays, and financial losses to contractors. Traditionally. this structure is fabricated at elevation using scaffolds; however, this approach is costly, time-consuming, and labour-intensive. We introduce a procedure for lifting a 600 metric ton structure that has been fabricated on the ground with a synchronous hydraulic jack-up system. We also discuss the technical difficulties of integrating such a structure into a housing facility. This note addresses several challenging issues: high-accuracy fabrication, design of preventing interference and deformation, and the development of a construction procedure. The case study may be helpful for the flexible construction of extended designs and for the use of a jack-up system in lifting heavy structures of massive sizes and weights.
