摘 要:为了控制超长水池裂缝的发展,通过对反冲洗水池壁板裂缝统计分析,提出了采用间歇式膨胀加强带代替连续式膨胀加强带的施工措施,并进行了现场试验性应用。结果表明:采用间歇式膨胀加强带可进一步限制和控制池体裂缝发展;间歇式膨胀加强带间歇时间7d~10d是合适的,实际施工间隔时间可根据现场实际情况适当微调,但不宜小于7d。可为同类水池、泵房类构筑物的变形缝设计提供参考。In order to control the process of cracks in super-long water tank,construction measures for using intermittent expansion strengthening band instead of continuous expansion strengthening band were proposed through statistical analysis on wall cracks of backwash water tank.And experimental application has been car-ried out.The results showed that intermittent expansion strengthening band can further restrict and control the process of the water tank wall cracks.It is appropriate for intermittent expansion strengthening band to be ap-plied intermittently over a period of 7 days~10 days.The actual construction interval time can be adjusted ac-cording to the actual situation,but should not be less than 7 days.This conclusion can be used for deformation joint design of similar water tank and pump house structures.
