Viaduct pier anchor cable grouting reinforcement method
The invention relates to the technical field of viaduct pile foundation reinforcement, in particular to a viaduct pier anchor cable grouting reinforcement method which comprises the steps that S1, drilling and grouting are conducted, specifically, at least one grouting hole channel is drilled in the circumferential side of a supporting pier column, and pressurized grouting is conducted after drilling of the grouting hole channel is completed; s2, soil body separation is conducted, specifically, a plurality of separation piles are inserted into the soil body to form a separation zone, and the separation zone divides the soil body into a pile foundation zone and an excavation zone; s3, foundation pit excavation is conducted, specifically, foundation pit excavation is conducted in an excavation area, a net is hung on the wall of a foundation pit, and then concrete spraying is conducted; a plurality of anchor cable hole channels are horizontally drilled in the pile foundation area, then reinforcing anchor cables penetrate through the corresponding hole channels, and the two ends of the reinforcing anchor cables are fixed to the separation belts after tensioning; s5, the step S3 and the step S4 are repeated until the excavation depth of the foundation pit reaches a preset value; the viaduct has the advantages that the position stability of the supporting pier columns is improved from multiple aspects, the influence of a newly-built road on the supporting pier columns is reduced, and the service life of the viaduct is prolonged.
本申请涉及高架桥桩基加固技术领域，尤其涉及一种高架桥桥墩锚索注浆加固方法，包括S1：钻孔注浆：于支撑墩柱的周侧钻设至少一个压浆孔道，并在压浆孔道钻设完成后进行带压注浆；S2：土体分离：将多个分隔桩插入土体中形成分隔带，且分隔带将土体分隔为桩基区和开挖区；S3：基坑开挖：于开挖区进行基坑开挖，并在基坑壁上挂网，然后进行混凝土喷射；S4：钻孔拉索：于桩基区上水平钻设多个锚索孔道，然后将加固锚索穿过对应孔道，张拉后将加固锚索两端固定于分隔带上；S5：重复步骤S3和S4，直至基坑开挖深度达到预设值；本申请具有从多方面提高支撑墩柱的位置稳定性，降低新建道路对支撑墩柱的影响以延长高架桥的使用寿命的效果。
