病害路基地基加固处理工程实例
摘要:针对胶济客运专线某段路基沉降加大的状况,提出以潜孔钻机开孔、以高压旋喷注浆加固地基的方案。在施工过程中,对高压旋喷注浆的工序进行合理打破常规的优化,既保证了既有铁路的运营安全,也保证了处理线路的质量,有效解决了本工程的难题。优化后的方案经过实践的检验,有进一步研究分析和推广的价值。
Abstract:To prevent the settlement of subgrade of Qingdao-Jinan only-passenger-transported railway, a scheme was suggested that the Down-hole drill was used to penetrate the filled soil, and high pressure jet grouting technique was adopted for reinforcing and strengthening the foundation. In the course of construction, the procedure of high pressure jet grating was optimized, this method does not only ensure the safety of the existing railway operation, but also give a guarantee to railway quality under construction, then the engineering problem was solved effectively. After the optimum scheme was testified, it would have the value to be analyzed further and extended.
