We often see dynamic compaction construction in daily life. Do you know the operation method of dynamic compaction construction measurement and setting out? In order to facilitate users to understand in detail, our staff will briefly introduce the relevant knowledge points to you.

1、强夯施工前，应将施工测量控制点引不受施工影响的地。2、建立现场坐标控制点及高程控制点。3、施放强夯区域线或单点夯区边线。4、夯区角点放线过错不大于20mm，夯点定位容许过错应为±50mm。5、测放初遍夯点方位，标出中心点及圆圈线并测量夯前场所高程。6、初遍强夯夯完整平后施放二遍夯点方位，重复第3项作业，其他遍数依此类推。

1. Before the dynamic compaction construction, the construction survey control points should be led to the ground not affected by the construction. 2. Establish site coordinate control points and elevation control points. 3. The line of dynamic compaction area or the side line of single point compaction area. 4. The setting out fault of corner point in tamping area shall not be greater than 20mm, and the allowable fault of tamping point positioning shall be ± 50mm. 5. Measure and set out the orientation of the initial compaction point, mark the center point and circle line, and measure the site elevation before compaction. 6. After the initial dynamic compaction is completed and leveled, the position of the second compaction point shall be released, and the third operation shall be repeated, and the number of other times shall be the same.
