Grouting reinforcement and repair method for mortar rubble retaining wall
The invention relates to the technical field of mortar rubble retaining wall repairing, in particular to a grouting reinforcement repairing method for a mortar rubble retaining wall, which comprises the following steps: firstly, detecting the internal structure of the retaining wall to determine the damage severity of the retaining wall and the distribution condition of a high-risk instability area, and further formulating a grouting hole position layout scheme; a frame beam is constructed on the outer side of a retaining wall, the retaining wall can be reinforced firstly, grouting hole positions of inclined small guide pipes and inclined steel floral tubes are reserved in the frame beam according to a grouting hole position arrangement scheme, and drilling on the frame beam in the later period is avoided; a stable condition is provided for small guide pipe drilling grouting through the frame beam, then a stable condition is provided for inclined steel floral tube drilling grouting through small guide pipe grouting, a stable reinforcing system is formed for the inclined steel floral tube anchoring frame beam through inclined steel floral tube grouting, the problem that instability is prone to occurring in the repairing process is solved, and the repairing quality of the inclined steel floral tube anchoring frame beam is improved. And the later reinforcing stability can be greatly improved, the overall strength of the retaining wall structure is improved, and the service life of the retaining wall structure is prolonged.
本发明涉及浆砌片石挡墙修复技术领域，特别涉及一种浆砌片石挡墙注浆加固修复方法，通过先对挡墙内部结构进行检测，确定挡墙受损严重程度和高风险失稳区域分布情况，进而制定注浆孔位置布设方案；采用在挡墙外侧施工框架梁，能够对先挡墙进行加固，并根据注浆孔位置布设方案在框架梁上预留倾斜小导管和倾斜钢花管的注浆孔位，避免后期需要在框架梁上进行钻孔；通过框架梁设置为小导管钻孔注浆提供稳定条件，再通过小导管注浆为倾斜钢花管钻孔注浆提供稳定条件，通过倾斜钢花管注浆为倾斜钢花管锚固框架梁形成稳定的加固体系，不仅克服了修复过程容易失稳的问题，而且能够大大提升后期的加固的稳定性，提高挡墙结构的整体强度和寿命。
