膨胀加强带技术在翻车机房地下结构工程中的应用

大体积混凝土温度裂缝控制是地下混凝土结构工程施工中控制重点及难点。某码头工程翻车机房地下结构采用膨胀加强带代替闭合块(后浇带),同时使用Midas civil软件及一线通大体积混凝土测温系统对翻车机房漏斗梁混凝土温度及应力进行监测及分析,有效避免了混凝土温度裂缝的产生,同时缩短了工期,取得了较好的经济效益。

Application of expansion reinforcing band technology in roll-over machine room underground structure

The temperature crack control of mass concrete is the key and difficulty in underground concrete structure engineer.In the underground structure of roll-over machine room of a port,the expansion reinforcing is applied instead of the post-cast strip.With the assistance of Midas civil software and ISDN mass concrete temperature monitoring system,the temperature and stress of the hopper concrete beam is monitored and analyzed.This method avoids the formation of concrete temperature crack and reduces the construction time.It also achieves excellent economic benefit.
