路缘石施工工艺标准Technology standard
Construction technology standard for curbstones
路缘石【curb】指的是设在路面边缘的界石,简称缘石。它是作为设置在路面边缘与其它构造带分界的条石,起到保障行人,车辆交通安全和保证路面边缘齐整的作用,同时起到利于排除路面水的作用。
A curbstone refers to a boundary stone set at the edge of the road surface, abbreviated as a curbstone. It is a stone strip set at the edge of the road surface to separate from other structural zones, which plays a role in ensuring pedestrian and vehicle traffic safety, ensuring the smoothness of the road surface edge, and also helps to eliminate road water.
路缘石主要有:立缘石(侧石),平缘石(平石)、专用路缘石(包括弯道路缘石、隔离带路缘石、反光路缘石、减速路缘石)等。路缘石宜用石材或混凝土制作。
The main types of curbstones include standing curbstones (side curbstones), flat curbstones (flat curbstones), and specialized curbstones (including curved curbstones, median curbstones, reflective curbstones, and deceleration curbstones). The curbstone should be made of stone or concrete.

操作要点
Operation points
1、测量放线:
1. Measurement and laying out:
核对道路中心线无误后,依次丈量出路面边界,进行路边线放样,定出边桩以控制方向和高程。直线段的边桩与边桩间可拉施工线作准绳,桩距为10m;曲线弯道及交叉路段均按设计半径,加密边桩,桩距为5m,路口桩距为1~5m,保证曲线圆弧尺寸。宜用全站仪、经纬仪、水准仪测设。
After verifying the accuracy of the road centerline, measure the boundary of the road surface in sequence, set out the roadside lines, and determine the boundary stakes to control the direction and elevation. The construction line can be used as a guide between the edge piles of the straight section, with a distance of 10m between the piles; Curves, bends, and intersections are all reinforced with edge stakes according to the design radius, with a distance of 5m between stakes. The distance between stakes at intersections is 1-5m to ensure the size of the curve arc. It is advisable to use a total station, theodolite, and level to measure and set up.
2、路缘石安装:
2. Installation of curbstones:
钉桩挂线后,沿基础一侧把路缘石依次排好。安装路缘石之前,先支模浇筑100mm厚C15混凝土垫层,再拌制1:2砂浆铺底,砂浆厚30mm,按放线位置安装路缘石。
After nailing the stakes and hanging the lines, arrange the curbstones in sequence along one side of the foundation. Before installing the curbstone, first support the formwork and pour a 100mm thick C15 concrete cushion layer, then mix a 1:2 mortar base with a thickness of 30mm, and install the curbstone according to the layout position.
事先计算好每段路口路缘石块数,砌筑时路段短时由一侧路口切点安砌到另一侧路口切点;路段长时由中间向两端铺砌与路口异型缘石顺接。
Calculate the number of stones on the edge of each intersection in advance, and during masonry, the road section will be temporarily laid from the intersection point on one side to the intersection point on the other side; For a long period of time, the road section is paved from the middle to both ends and connected smoothly with the irregular edge stones at the intersection.
路缘石调整块应作机械切割成型或以现浇同强度等级混凝土制作,不得用砖砌抹面方式做路缘石调整块,雨水口处的路缘石应与雨水口配合施工,相邻路缘石缝隙用8mm厚铁板或塑料板控制,相邻路缘石的缝隙应均匀一致。
The whole piece of curbstone adjustment should be mechanically cut or made of cast-in-place concrete of the same strength grade. It is not allowed to use brick masonry and plastering to make the whole piece of curbstone adjustment. The curbstone at the rainwater inlet should be constructed in coordination with the rainwater outlet. The gap between adjacent curbstones should be controlled by 8mm thick iron or plastic plates, and the gap between adjacent curbstones should be uniform and consistent.
路缘石安装后,必须再挂线,调整路缘石至顺直、圆滑、平整,对路缘石进行平面及高程检测,当平面及高程超过标准时应进行调整。无障碍路缘石应按设计要求安装。路缘石安装合格后及时采用C15混凝土进行后背浇筑和水泥砂浆勾缝,以保证路缘石稳定。采用湿法养生3天,其间应防止碰撞。
After the installation of the curbstone, it is necessary to hang a line and adjust the curbstone to be straight, smooth, and flat. The curbstone should be checked for its level and elevation. When the level and elevation exceed the standard, adjustments should be made. Barrier free curbstones should be installed according to design requirements. After the installation of the curbstone is qualified, C15 concrete should be used for back pouring and cement mortar jointing in a timely manner to ensure the stability of the curbstone. Adopt wet health preservation for 3 days, during which collision should be prevented.
3、路缘石安装的基本要求:
3. Basic requirements for installing curbstones:
