| 按测量设定的平面与高度位置刨槽、找平、夯实后安装路沿石。打桩挂线（双挂线法）后，沿基础一侧把路沿石依次排好。路缘石垫层用1:3石灰浆找平，虚厚约2cm。路缘石背后选用水泥混泥土浇筑三角支撑，回填用灰土夯实，夯实宽度不应小于50cm，高度不应小于15cm，压实度不应小于90％,以保证路缘石稳定。采有湿法养生3d，其间应防止碰撞。 According to the measured plane and height position, planing, leveling, tamping and installing the curb stone. After piling and hanging line (double hanging line method), row the stone along the side of the foundation. The kerb cushion is leveled with 1:3 lime slurry, and its thickness is about 2cm. Cement-concrete soil is used to pour triangular support behind the curb stone, and lime-soil is used to compact the backfill. The compaction width should not be less than 50 cm, the height should not be less than 15 cm, and the compaction should not be less than 90% to ensure the stability of the curb stone. Adopt wet method health 3D, should prevent collisions. |
