CAISSON TUBE WATER-TIGHT STRUCTURE AND UNDER WATER STRUCTURE CONSTRUCTION METHOD FOR SOFT GROUND

摘要

The poor ground wire of girth sluice tightening structure and a kind of construction submerged structure, so that the poor ground constructed on underground structure such as bridge pier is disclosed. Girth sluice tightening structure, make the low side of cofferdam soft foundation by the ground supports article that the poor does not check and approve according to suitable program but supports support pile riverbed the poor ground, prevent sinking of cofferdam, even if being placed in riverbed the poor ground from low side cofferdam, with end shape lower end, convenient for constructing and removing for fastening. The poor ground configurations of girth sluice tightening structure are rapidly and easyly constructed the poor ground, construction period and construction cost are reduced, because submerged structure is configured in drying regime. ;The 2014 of copyright KIPO submissions
