Construction requirements and precautions of road edge stone

石材路缘石应石质一致，无裂纹和风化等现象。花岗岩保水极限抗压强度应不小于100MPa，洛杉矶法磨耗率小于30%，狄法尔法磨耗率小于5%。石材路缘石的放射性水平应满足放射性比活度CRae≤1000Bq/kg镭当量浓度。

The stone curb should be consistent with stone without cracks and weathering. The ultimate compressive strength of granite should be not less than 100MPa, the abrasion rate of Losangeles method is less than 30%, and the wear rate of the method is less than 5%. The radioactivity level of stone curb should meet the radioactive specific activity of CRae less than 1000Bq/kg radium equivalent concentration.

侧、平石施工

Side and flat stone construction

路缘石应安砌稳固，做到线直、弯顺、无折角，顶面应平整无错牙，现具业主要求不得用水泥砂浆勾缝。

The curb should be firmly built, straight, bent and no corner. The top surface should be smooth without wrong teeth.

路缘石必须在沥青面层施工前安装完毕同时在沥青面层施工时加以保护，以防止污染。

The curb must be installed before the asphalt pavement is constructed and protected during the asphalt pavement construction to prevent contamination.

路缘石埋置后应将回填材料压实或采取保护措施，防止面层施工时变形，严禁在各层沥青面层铺筑后再开挖面层埋设缘石。

After the gravel is buried, the backfill materials should be compacted or protected to prevent the deformation of the surface layer, and it is forbidden to lay the edge stone in the surface layer after the asphalt pavement is paving.

路缘石后背混凝土C20混凝土。

RC back concrete C20 concrete.

对运到施工现场的路缘石再次进行检查，应轻拿轻放，避免损坏，强度不合格、色泽不一致、外观尺寸误差5mm、是否有缺棱、角、坑窝、裂纹、颜色不一致等现象，对检验不合格的一律不使用。

To check the road stone that is transported to the construction site again, it should be taken lightly to avoid the damage, the strength is not qualified, the color and lustre is not consistent, the appearance size error 5mm, the lack of edge, the angle, the pit, the crack and the color are not consistent, so it is not used for the inspection of the unqualified.

2、测量放样

2. Measurement of lofting

路缘石安装前，应校核道路中线，测设路缘石安装边桩和高程控制桩，直线段桩距为10m，曲线段不大于5m，路口为1～5m。按照设计高程进行控制测量。

Before the installation of the road edge stone, we should check the middle line of the road, set up the edge stone to install the side pile and the height control pile, the straight section pile distance is 10m, the curve section is not more than 5m, the intersection is 1 ~ 5m. Control measurements are carried out according to the design elevation.

3、路缘石运输

3, road border stone transportation

⑴路缘石的运输，要求厂方对路缘石块与块、层与层之间安设夹板，并且进行四角包装，确保路缘石的完好。

1. The transportation of the curb stone requires the factory to install splint between the curb blocks and blocks, layers and layers, and carry out packing in four corners to ensure the integrity of the curb.

⑵路缘石在经业主及监理批复的厂方进行加工制造。路缘石出厂时必须检验合格。运到施工现场后，材料质检员按规范对其构件进行查收检验，及时抽样送检和见证取样，并有质量合格证和质量检验报告。

2. The curb stone is processed by the manufacturer approved by the owner and the supervisor. The road edge stone factory must be inspected. After being transported to the construction site, the material quality inspector inspected its components according to the standard, sampling inspection and witness sampling in time, and having quality certificate and quality inspection report.

⑶第一次运输，由加工厂用叉车装车，汽车运到现场人行步道的两树池间存放，并设安全提示标识。

(3) the first transportation is carried out by the forklift truck at the processing plant, and the vehicle is transported to the two pools of the pedestrian walkway on the spot.

⑷第二次运输安装前，使用小型叉车运到安装地点间隔码放，随使用随运输。安装后，剩余的路缘石及时运回人行步道指定地点，并用绿网苫盖设安全提示标识。

Before the second transport installation, use small forklift truck to carry out the installation at intervals, with the use of transport. After installation, the remaining kerbs will be transported back to the designated places of the pedestrian walkway and the safety signs will be set up with green net.

⑸路缘石在运输过程中，保证不碰撞轻拿轻放，避免损坏。运到施工现场的路缘石要及时安装。

During the transportation process, the curb kerbs should be protected against collision and light damage. The road stones shipped to the construction site should be installed in time.

⑹异型缘石加工前，应根据设计图纸上标注的各路口圆弧半径数值与现场实际进行比对，如有误差及时通知设计人员进行修改、复核后，统一归纳编号后提供给生产厂家，厂家据此加工。

Before processing, the arc radius of each intersection should be compared with the actual field according to the numerical value of the circular arc radius marked on the design drawings. If there are errors in time to notify the designer to modify and recheck it, the manufacturer should be provided to the manufacturer and the manufacturer to process it.

4、路缘石安装

4. Installation of road edge stone

①垫层采用C20混凝土；M7.5水泥砂浆卧底，配比控制，现场设磅秤，按每袋水泥重量，称砂石水的重量，砂石水各设标准桶计量。

(1) the cushion is C20 concrete; M7.5 cement mortar undercover, proportion control, site set scale, according to the weight of each bag of cement, weighing the weight of sand and stone water, sand and stone water each standard barrel measurement.

②人工按放线位置安装路缘石。安装前，基础要先清理干净，并保持湿润。安装时，先用线绳控制路缘石的直顺度，再用水平尺进行检查，安装合格后及时采用C20混凝土进行后背浇筑。路缘石砌筑应平顺，相邻花岗岩路缘石缝用4mm厚铁板或塑料板控制，相邻混凝土路缘石缝用8mm厚铁板或塑料板控制，相邻路缘石的缝隙应均匀一致，路缘石与路面无缝隙、不漏水。

2. Install the road stone by the position of the artificial line. Before installation, clean the foundation and keep it moist. When installing, first use wire rope to control the curl of curbs, then check with a horizontal ruler. After installation, C20 concrete will be used for back pouring in time. Road edge stone masonry should be smooth, adjacent granite road edge stone seam with 4mm thick iron plate or plastic plate control, adjacent concrete road edge stone seam with 8mm thick iron plate or plastic plate control, adjacent road edge stone cracks should be uniform, road edge stone and pavement no gap, no leakage of water.

③花岗岩路缘石缝宽为5mm。

The width of the granite road margin is 5mm.

④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接顺。路口缘石按等高线坡化控制。

(4) the number of blocks of the road edge of each intersection is calculated in advance. When the road is built, the section of the road is built by the cutting point of one side intersection to the other side of the intersection. The edge stone of the intersection is controlled by the slope of the contour line.

⑤路口、隔离带端部等曲线段花岗岩路缘石，宜按设计弧形加工预制，单块长度不得小于70cm。不得使用小标准块进行拼接。路缘石的安装速度满足现场施工的需要，必须在上面层施工之前安装好。

5. The granite kerbs at the ends of the intersection and the ends of the isolation belt should be prefabricated according to the design arc, and the length of the single block should not be less than 70cm. It is not allowed to use small standard blocks for splicing. The installation speed of kerbs meets the needs of site construction, and must be installed before the upper layer construction.

⑥路缘石安装后检验，必须再挂线，调整侧石直顺、圆滑、平整及高程检测，每20m检测一点，当平面及高程超过标准时应进行调整。

After the inspection of the road edge stone, the line must be hung again to adjust the side stone straight, smooth, smooth and leveling, and every 20m should be detected, and the adjustment should be made when the plane and the elevation exceed the standard.

⑦场地清理：路缘石安装完毕后，及时对有污染的场地和路面进行清理。

Site cleaning: after the installation of the curb stone, clean the contaminated sites and roads in time.

⑧已完工的路缘石用塑料薄膜苫盖，进行成品保护，防止损害及表面污染。

The finished kerb is covered with plastic film to protect the finished product from damage and surface contamination.

5、无障碍道口及养护

5, barrier free crossing and maintenance

①砌筑路缘石时需根据施工图设计要求，在斑马线位置预留盲道出入口。各个路口按照规范做无障碍设施。

1. When constructing the curb, the blind road entrance and exit should be reserved in the zebra crossing according to the design requirements of the construction drawings. Every intersection will be a barrier free facility according to the standard.

②在施工时，现场如有出入，应及时与监理、设计单位进行汇报，共同商讨解决办法。

2. During construction, if there is any discrepancy in the site, it should report to the supervision and design units in time and discuss the solutions together.

6、检测及成品保护

6, inspection and product protection

施工中采用水平尺进行控制，砌筑应稳固，顶面平整，线条直顺，曲线圆顺，缝宽均匀，无杂物污染，然后采用塑料薄膜覆盖进行成品保护。

In the construction, the horizontal ruler is used to control, the masonry should be stable, the top surface is smooth, the line is straight, the curve is round, the seam width is uniform, no sundries are polluted, and the plastic film cover is used to protect the finished products.

7、异型缘石施工

7. Construction of heteromorphic stone

⑴砌筑异型缘石前，要先对圆弧进行放线，在地面放出标准尺寸圆弧，然后按照大样图先进行预装，与放出的圆弧线进行比较，满足圆弧后方可进行正式砌筑，如果不满足圆弧要求，应先用打磨机等机械对缘石进行二次加工，满足圆弧后方可使用。

Before laying the irregular edge stone, the circular arc should be placed first, the standard size arc is released on the ground, then the preloading is first carried out according to the large pattern, and the circular arc line is compared with the released arc line to satisfy the circular arc. If the circular arc is not satisfied, two processing should be done with a grinding machine, such as a grinding machine. It can be used in the rear of the arc.

⑵异型缘石砌筑应从一侧开始，顺序砌筑，外观应圆顺。

2. The construction of irregular shaped stones should start from one side, in sequence, and the appearance should be round.

⑶路口及人行过街的无障碍缘石坡
