对于强夯地基置换的计划有什么要求?

强夯地基置换时,应在试夯时仔细记载并做出合理的报价。强夯置换时地面不可避免地提高,特别是在粘性土中拱起的体积明显。
During dynamic compaction foundation replacement, it shall be carefully recorded and a reasonable quotation shall be made during trial compaction. The ground will inevitably increase during dynamic compaction replacement, especially in cohesive soil.
1、强夯地基施工需要严格按照实验认可的技术参数进行操作。夯实深用水平仪测量控制。
1. The construction of dynamic compaction foundation shall be carried out in strict accordance with the technical parameters approved by the experiment. The compaction depth shall be measured and controlled with a level.
2、每次夯实后,测量场所均匀下沉量,填平夯实坑,进行下一次夯实,施工均匀下沉量一定要满足计划要求。
2. After each compaction, measure the uniform settlement of the site, fill the compaction pit, and carry out the next compaction. The uniform settlement of the construction must meet the plan requirements.
3、强夯地基施工时,首先要检查夯实锤是否在中,如有疼痛,用锤边焊接钢板或增减凝土等方法平衡,避免夯实孔倾斜。
3. During the construction of dynamic compaction foundation, first check whether the tamping hammer is in. If there is pain, balance it by welding steel plate at the hammer edge or increasing or decreasing concrete to avoid the inclination of tamping hole.
4、夯击时,落锤应稳定,夯击位置正确。错位或坑底倾斜过大时,应立即平整坑,加固后进行下一道工序。
4. During tamping, the falling hammer shall be stable and the tamping position shall be correct. In case of dislocation or excessive inclination of the pit bottom, the pit shall be leveled immediately and the next process shall be carried out after reinforcement.
5、强夯时,地基和周围建筑物发生一定的振动,强夯点应距现有建筑物15米以上,间隔不足时,强夯点与建筑物之间可挖掘隔振槽带,其槽深应跨越建筑物的基础深,具有满意的长或强夯地基场所。
5. During dynamic compaction, the foundation and surrounding buildings vibrate to a certain extent, and the dynamic compaction point shall be more than 15m away from the existing buildings. If the interval is insufficient, a vibration isolation groove belt can be excavated between the dynamic compaction point and the buildings, and its groove depth shall span the foundation depth of the buildings, with a satisfactory length or dynamic compaction foundation site.
