The shipbuilding dock project in the western zone by Shanhaiguan Shipbuilding Industrial Co.,Ltd. has such features as complicated structures, large work quantity and tight work schedules, etc.Therefore, a series of key control measures are taken during the pier construction of the ship dock, including reasonable division of blocks and lifts, control of concrete construction time and interval of structural lift division, formwork technique of reducing lateral structural constraint, heating radiating hole provision and block stone embedment in the dock pier concrete, concrete curing and temperature-measuring control, etc., which achieved the effects of no seepage, no leakage and no cracking of the whole dock, and a good apparent quality of concrete as well.
