根据本工程条件，采用 6t ～ 10t 的压路机满基坑铺筑压实，不 得

According to the conditions of this project, 6t ~ 10t rollers are used to lay the foundation pits for compaction and no sectioning is allowed. The number of tamping or rolling passes is determined by field test. It is planned to first static pressure twice, vibration rolling not less than 4 times, the roller is strictly prohibited to use vibration within 5m from the adjacent building, only static pressure, static pressure variable not less than 10 times. The rolling speed is planned to be 40m / min, and the overlapping width of the rolling track is not less than 50cm. The edges and corners should be compacted by manual or frog-type ramming machines.

根据本工程条件，采用 6t ～ 10t 的压路机满基坑铺筑压实，不 得分段。夯实或碾压的遍数，由现场试验确定。拟定先静压两遍，振动碾压不少于 4 遍，压路机在距离相邻建筑 5m 范围内严禁使用振动，只能静压，静压变数不少于 10 遍。碾压速度拟定 40m/min, 碾压轨迹搭接宽度不少于 50cm 。边缘和转角处应用人工或蛙式打夯机补夯密实。

According to the conditions of the project, 6T ~ 10t road roller is used to pave and compact the foundation pit in full, and sections are not allowed. The number of times of compaction or rolling shall be determined by field test. It is proposed that static pressure shall be applied for two times and vibration rolling shall not be less than four times. It is strictly forbidden to use vibration within 5m from adjacent buildings. Only static pressure can be applied, and the static pressure variable shall not be less than 10 times. The rolling speed is proposed to be 40m / min, and the overlapping width of rolling track is not less than 50cm. The edge and corner shall be compacted by hand or frog rammer.<br>
