摘　　要：为提高河流型碧道现状隐患挡墙改造施工效率、节约工程施工工期及成本、减少汛期施工风险,以龙岗河干流碧道现状凹凸型混凝土结构挡墙改造工程为例,分析对比拆除重建挡墙、批灰刷腻子等工艺更适用于该环境,且该施工技术采用角向磨光机抛光翻新、涂抹着色剂调色、喷涂水性混凝土保护硅透明漆进行混凝土表面保护,对周边环境影响小、操作便捷、观赏价值高,经济环保。In order to improve the construction efficiency of the current hidden danger retaining wall renovation of river type greenway,save the construction period and cost,and reduce the construction risks during the flood season,this paper takes the example of the concave convex concrete structure retaining wall renovation project of the main stream Bi Dao of Longgang River,and analyzes and compares the demolition and reconstruction of the retaining wall,the application of putty and other processes that are more suitable for this environment.This construction technology uses an angle grinder to polish and renovate,apply colorants for color adjustment,and spray water-based concrete protective silicone transparent paint for concrete surface protection.It has little impact on the surrounding environment,is easy to operate,has high ornamental value,and is economical and environmentally friendly.
