During the construction of current very large container ship, due to the hatch cover problems in the accuracy deviation of construction body, transportation and lay-down, and installation process, there appears the container foot modification phenomenon in the subsequent container stack test. In order to ensure the rapid and accurate container foot modification, by studying the container foot stay levelness confirmation method, the problems in data acquisition, application and on-site actual operation of three-dimensional measurement technology based on the total station instrument are solved, so as to realize the organic integration of three-dimensional measurement analysis and on-site actual construction, to promote the accuracy of on-site construction, and to ensure the one-time completion of container foot modification. Through the on-site popularization and application, it is verified that the scheme can realize the accuracy and wide applicability of container foot installation, and the economic and social benefits brought by the technology are analyzed according to the application effect.
