摘要
当采用二次高压劈裂注浆法施工时,规范上规定的浆液水灰比常常不容易达到要求,结合具体工程的实例,针对永久性锚杆的浆液配合比、二次高压劈裂注浆套管及密封装置等问题提出了一些具体做法和建议。
When using twice high pressure splitting grouting technology in anchor rodconstruction,the water cement ration gived by the code often is not satisfied the demands.Combining a practical project,authors present some specific methods and suggestions on the twice high pressure splitting grouting,such as mix ratio of grout,casing tube and sealing arrangement,etc.
