摘 要:路缘石作为保证道路宽度整齐的界石,一般在道路的边线土地上开槽安装。开槽安装时,如果基础处理不好,则容易出现沉降、歪斜等质量问题,极大地影响道路的整体美观性。以引江济淮工程中试量水库环库堤顶道路路缘石施工为例,针对在水泥稳定碎石层开槽铺设路缘石的施工工艺展开分析,以期为类似工程提供参考。

Abstract: As a boundary pillar to ensure the neat width of the road, curb has always played an important role. Kerbs are generally slotted and installed on the land along the roadside. If the foundation is not well handled, it is prone to quality problems such as settlement and skew, which greatly affects the overall aesthetics of the road. Taking the construction of kerbs on the top of the ring reservoir embankment of the pilot reservoir of the Yangtze River to Huaihe River project as an example, this paper analyzes the construction technology of slotting and laying kerbs in the cement stabilized gravel layer, Good results have been achieved in the construction, which provides a reference for similar projects.

路缘石是安装在路面上用以区分车行道、人行道、綠地、隔离带以及道路其他部分的界线,起到保障行人、车辆交通安全和保证路面边缘整齐的作用。随着路缘石的广泛应用,它的需求量越来越大。现有路缘石根据材质通常可分为普通混凝土预制和石材加工两大类。随着经济技术的发展进步和成本控制意识的提高,混凝土预制路缘石在实际应用中的占比越来越高。
路缘石在施工中不是工程主体,施工质量常常得不到重视,极易产生沉降、歪斜甚至部分断裂等现象,严重影响路面工程的整体外观形象和附属工程的使用质量[1]。因此,严格控制路缘石的安装施工质量具有十分重要的意义。
1 工程概况
引江济淮工程试量调蓄水库工程为人工开挖的调蓄水库,如图1所示。库底开挖高程为37.00 m,平均开挖深度为5.00 m;调蓄水库正常蓄水位为40.90 m,设计水深为3.90 m;死水位高程为37.50 m,库底高程为37.00 m;调蓄库容为700 000 m3,总库容为800 000 m3。
为满足巡视和维修检查等交通功能要求,堤顶设置防汛道路,全长共计1.95 km,高于现状地面约2.40 m。……
