　　B体育官网厦门某中学塑胶跑道运动场施工方案    首先在已有建筑物外墙面离地面0 . 5 m 左右测设固定水准点，其精确度不应

　　     根据图纸要求B体育官网，砖砌检查井用实心砖M U 1 0 ，M 1 0 水泥砂浆砌筑。井底要求

　　用一台推土机整平，最后用压路机在原土面上压3 —5 遍。基槽两边沿线 . 水泥碎石垫层的施工

　　垫层厚 1 5 c m ，铺设时，应让碎石高出标高桩 3 至 5 c m 。水泥级配碎石用自卸汽

　　    跑道垫层完工后即可施工路缘石，先用2 c m 厚1 ：2 . 5 水泥砂浆卧底坐浆，

　　    砼运输距离尽量控制在1 0 0 m 以内，以避免砼在运输过程产生离析泌水现象，
