Lifting Building Technology to Mitigate Differential Settlement

Abstract

This article is a part of the thesis titled “Lifting Building Technology to Mitigate Differential Settlement”, Master of Architecture, Department of Architectural Technology, King Mongkut’s Institute of Technology Ladkrabang, aiming to gather technologies associated with repairing sinking buildings for obtaining components and factors affecting the building repair through collecting literature reviews, interviewing persons in charge, and doing field work at 2 to 5 storeyed buildings in Samut Sakhon, Khon Kaen and Bangkok. Basic data of each building related to building repairing were collected from engineers, soil survey teams, staff of soil testing laboratories, and building repair technicians. Based on the field work observation, it was found that there were 4 types of piles used for repairing building which are bore pile, composite pile, hollow steel pile (Ø), and steel H-pile (H). Basic data were collected and processes of repairing were classified. The obtained data were analyzed together with theories of technology component so as to get to know reasons that lead to repair each building to find out the study conclusion. The findings from the study showed that building lifting technology for repairing sinking building was to further develop the body of knowledge in applying piles and instruments in repairing. There were similarity and difference in details for using each type of pile in each procedure depending on readiness situation of areas, safe load of each type of piles, transportation including management process of management team and engineers
