In the process of mass concrete construction,in order to meet the requirement of concrete temperature control and joint grouting,cooling water pipe should be embedded in the concrete for cooling.With combination of bi-directional difference method and FEM,the computation and comparison analysis on cooling effect of flexible pipe and black pipe in TGP are carried out.The results demonstrate that compared with black pipe,under the same layout of pipe systems and the same water volume passing through the pipes,the...

In the process of mass concrete construction,in order to meet the requirement of concrete temperature control and joint grouting,cooling water pipe should be embedded in the concrete for cooling.With combination of bi-directional difference method and FEM,the computation and comparison analysis on cooling effect of flexible pipe and black pipe in TGP are carried out.The results demonstrate that compared with black pipe,under the same layout of pipe systems and the same water volume passing through the pipes,the temperature drop effect of the flexible pipe will reach the same as that of black pipe if the cooling water circulation in flexible pipe is prolonged by 4~6 d in middle and later stage.Average maximum concrete temperature for foundation constraint zone by using flexible pipe is 0.3℃~0.4℃ higher than that by black pipe in summer.If the flexible pipe is embedded in the middle of concrete lift,the average maximum temperature is about 0.2℃ lower than that if the black pipe is embedded in surface layer.Using flexible pipe for TGP,it will save 11~16 million yuan.Placing the flexible pipe in the middle of concrete lift is favourable for speeding up the dam concrete construction.

在大体积混凝土施工过程中 ,为满足混凝土温控及接缝灌浆的要求 ,需在其体内埋设冷却水管进行通水冷却。利用双向差分法和有限元法相结合 ,对三峡大坝采用软冷却水管和黑铁管的冷却效果进行了计算与对比分析。结果表明 :采用软管与黑铁管相比 ,在相同的水管布置型式和相同的通水量情况下 ,中后期只需将软管的通水时间延长 4~ 6d,就可以达到与黑铁管相同的降温效果 ;夏天浇筑基础约束区采用软管进行初期通水 ,基础约束区的平均最高温度较采用铁管要高 0 .3℃~ 0 .4℃ ,若将软管埋在浇筑层中间 ,其平均最高温度较铁管埋在层面要低 0 .2℃左右 ;三峡大坝采用软管 ,可节省费用 110 0~ 160 0万元左右。在浇筑层中间铺设软管为加快坝体混凝土的施工进度提供了有利条件。
