摘　　要：为提高支护结构的拉拔力,控制边坡滑动位移,以分洪渠河道工程为例,开展加固边坡挂网锚喷支护施工技术的研究。该技术通过综合应用边坡修整、混凝土喷射、锚杆注浆与挂网施工等措施,形成一个整体稳定的支护结构。清理基面,进行边坡作业面与基面的修整;制备混凝土,并进行作业面的喷射施工;注浆完成后,立即插入锚杆,利用砂浆或水泥浆将锚杆与周围岩土体紧密结合,进一步增强边坡的稳定性。随后进行砂浆锚杆与挂网施工,通过挂网和锚杆的联合作用,将边坡土壤和岩石紧密连接在一起,形成一个更加稳定的支护体系。最后,进行锚杆注浆与混凝土养生。完成施工后,对作业面进行质量验收。验收结果证明:按照规范进行分洪渠河道加固边坡挂网锚喷支护施工,可以在控制支护作业面滑动位移的同时,提高支护锚杆的拉拔力。In order to improve the pull-out strength of the support structure and control the sliding displacement of the slope,taking the flood diversion channel project as an example,a study is carried out on the construction technology of reinforcing the slope with hanging nets,anchoring and spraying support.This technology integrates slope reshaping,concrete spraying,anchor grouting,and netting construction to form a stable,cohesive support structure.The process begins with cleaning the base surface and reshaping the slope working face and base.Concrete is then prepared and sprayed onto the working surface.After grouting,anchor rods are immediately inserted,and mortar or cement slurry is used to bond the anchor rods with the surrounding soil and rock,further enhancing the slope’s stability.Next,mortar anchors and netting are installed.The combined effect of the netting and anchor rods tightly connects the slope soil and rock,forming a more stable support system.Finally,anchor rod grouting and concrete curing are performed.After construction is completed,the working surface undergoes quality inspection.The inspection results show that the slope reinforcement using netting,anchoring,and shotcrete support in accordance with the standards can control the sliding displacement of the support working surface while improving the pull-out strength of the anchor rods.
