灌浆技术处治桥头搭板脱空、沉陷应用探讨

Application of Injection Grouting Technique in Cavity and Sinking Treatment of Transition Slab at Bridge Head

对京石高速公路采用灌浆技术处治桥头搭板沉陷,经过通车试验,没有发现任何桥头搭板脱空、唧浆等现象,收到了良好的使用效果,可供施工部门参考。

Handled for sinking of transition slab at bridge head by injection grouting technique, Beijing-Shijiazhuang expressway has been proved by traffic-open test to have no cavity at transition slab at bridge head, mud jacking, and other diseases. It is obvious that this handling engineering has got good effect and can be referred by similar constructions.
