路肩石施工要点
Key Points of Road Shoulder Stone Construction
1)测量放样
1) Measurement lofting
安装前,应校核设计中线,测设安装控制桩,直线段桩距为10m,曲线段不大于5m。按照设计高程进行控制测量。
Before installation, the design line should be checked and control piles should be installed. The pile spacing of straight line section is 10 m and the curve section is less than 5 m. Control measurement according to design elevation.
2)运输
2) transport
预制件在运输过程中,应放置平稳,避免损坏。运到施工现场的要及时安装,若不能及时安装完毕要与其他材料沿路面一侧摆放整齐,不能影响路容路貌。
Prefabricated parts should be placed smoothly during transportation to avoid damage. When it arrives at the construction site, it should be installed in time.

(2) 统一采用坐浆法施工,垫层砂浆厚10mm,不允许污染预制块和路面。安装前,基础要先清理干净,并保持湿润。
(2) Constructing by sitting slurry method, the thickness of cushion mortar is 10mm, and pollution of prefabricated blocks and pavement is not allowed. Before installation, the foundation should be cleaned and kept wet.
(3) 安装时,用线绳控制直顺度,相邻缝用8mm厚木条或塑料条控制,缝隙宽不应大于10mm。
(3) When installing, the straightness should be controlled by rope, and the adjacent seams should be controlled by 8 mm thick wood or plastic strips. The width of the seam should not be greater than 10 mm.
(4) 相邻预制块的缝隙应封严且均匀一致。路肩石与沥青混凝土路面无缝隙。
(4) The gap between adjacent prefabricated blocks should be sealed and uniform. There is no gap between the shoulder stone and the asphalt concrete pavement.
(5) 应事先计算好每段所需块数。路肩石安装时要与泄水槽的喇叭口、结构物圆滑地相接,线条直顺,曲线圆滑美观。
(5) The number of blocks required for each paragraph should be calculated in advance. Shoulder stones should be installed smoothly with the trumpet mouth and structure of the drainage tank. The lines are straight and the curves are smooth and beautiful.
