摘要
通过工程实例,介绍了预应力管桩受损后采用套管法水下砼灌注工艺灌注桩心砼结合后压浆工艺对管桩断裂面注浆加固的工艺方法,并对实际施工前后的检测结果进行了对比。
The damage of pre-stressed pipe pile was treated by concrete core grouting of cast-in-place pile with casing underwater cement grouting technology and grouting reinforcement for fracture surface with post grouting in field cases, comparison was made on test results around the construction operation.
