旧闸改建中闸墩加高设计比较关键 ,需要新老混凝土粘结良好 ,以承担由牛腿传递来的巨大弧门推力。张庄闸改建加固工程的闸墩设计充分利用老闸墩的钢筋 ,合理布置和配备插筋 ,解决了新老混凝土的粘结问题 ,从而保证了闸墩的整体性。 Old gates in the design of the pier pier elevation more critical, the need for good bonding of new and old concrete to take over by the leg to the huge arc gate thrust. The gate pier design of the Zhangzhuang sluice reconstruction and reinforcement project makes full use of the steel bars of the old sluice pier, rationally arranges and inserts reinforcing bars, and solves the problem of the bond between new and old concrete so as to ensure the integrity of the sluice pier.
