Abstract
The characteristics and difficulties of riverside hub lock chamber in Xingouhe extension and dredging project are analyzed. The lock floor and pier wall is large volume concrete,single section concrete pouring quantity is large,quality requirements are high. For solving the common defects of cracks in concrete construction and appearance quality of lock chamber,according to the construction process,the construction program is optimized. Aspects as follow:fabrication and installation of steel and formwork,concrete mix ratio,pouring layer,temperature control,vibration,conservation,backfill behind the wall,other details and quality assessment of the project are explored. The corresponding technical measures are proposed.关键词
