Reinforcing method for rear anchoring structure of longitudinal connecting plate type ballastless track platform
The invention discloses a method for reinforcing a rear anchoring structure of a longitudinal connecting plate type ballastless track platform. The method comprises the following steps: filling voids below a friction plate and around end spines by adopting a static pressure grouting technology, and performing compaction and permeation reinforcement on loose soil below the friction plate and around the end spines. According to the method, a sleeve sealing pipe grouting reinforcement technology is adopted for solving the problems of friction plate lower disengaging and soil body loosening. The technology comprises the steps of punching, grouting pipe installing and grouting. According to the method, a pipe retreating sleeve valve pipe grouting reinforcement technology is adopted for solving the problems that the periphery of an end thorn is disengaged and a soil body is loose. The technology comprises the steps of drilling, grouting pipe inserting, grouting, pipe lifting and circulating grouting. According to the method, the two processes are combined, so that the stability performance of the anchoring structure behind the abutment can be effectively recovered, and the service performance of the longitudinal connecting plate type ballastless track is improved; and the method is mature in related process, small in work amount and rapid in construction, and can be implemented within the skylight time of a business line.
本发明公开了一种纵连板式无砟轨道台后锚固结构的加固方法，所述方法采用静压注浆技术填充摩擦板下及端刺周围脱空，并对摩擦板下和端刺周围松散土体进行挤密和渗透加固。所述方法针对摩擦板下脱空和土体松散问题采用套封管注浆加固工艺，所述工艺包括：打孔、装注浆管和注浆；所述方法针对端刺周围脱空和土体松散问题采用退管袖阀管注浆加固工艺，所述工艺包括：钻孔、插设注浆管、注浆、提管、循环注浆。所述方法中两种工艺结合可有效恢复台后锚固结构的稳定性能，提升纵连板式无砟轨道的服役性能；且所述方法相关工艺成熟、工程量小、施工快捷，可在营业线天窗时间内实施。
