软土地基施工使用强夯置换要具备特点

对于强夯施工大家应该都有了解,强夯置换其实跟强夯施工的原则是相同的,今天我们强夯机出租小编给大家分析一下加固软土地基时候的施工要点都有什么呢,一起来了解下吧。
Everyone should know about dynamic compaction construction. The principle of dynamic compaction replacement is actually the same as that of dynamic compaction construction. Today, we rent a small series of dynamic compaction machines to analyze the key points of construction when strengthening soft soil foundation. Let's have a look.
1.施工场地应平整并能承受夯击机械的荷载,施工前必须所有障碍物及地下管线。
1. The construction site should be flat and able to bear the load of tamping machinery. All obstacles and underground pipelines must be removed before construction.
2.强夯机械必须符合夯锤起吊重量和提升高度要求,并设置装置,防止夯击时起重机臂杆在突然卸重时发生后倾和减少臂杆的振动。装置一般采用在臂杆的顶部用两根钢丝绳锚系到起重机前方的推土机上。不进行强夯时,推土机可作平整场地用。
2. The dynamic compaction machine must meet the requirements of the lifting weight and lifting height of the rammer, and safety devices must be set to prevent the crane boom from tilting backward and reduce the vibration of the boom during sudden unloading during compaction. The safety device is generally tied to the bulldozer in front of the crane with two wire rope anchors at the top of the boom. When dynamic compaction is not carried out, the bulldozer can be used for leveling the site.
3.强夯施工,必须严格按照试验确定的技术参数进行控制。夯击深度应用水准仪测量控制。
3. The dynamic compaction construction must be strictly controlled according to the technical parameters determined by the test. The tamping depth shall be measured and controlled by level gauge.
4.每夯击一遍后,应测量场地平均下沉量,然后将夯坑填平,方可进行下一道夯实,施工平均下沉量必须符合设计要求。
4. After each tamping, the average settlement of the site shall be measured, and then the tamping pit shall be filled up before the next tamping. The average settlement of the construction must meet the design requirements.

5.强夯时,先应检验夯锤是否处于中心,若有偏心时,应采取在锤边焊钢板或增减混凝土等办法使其平衡,防止夯坑倾斜。
5. During dynamic compaction, check whether the rammer is in the center. If there is eccentricity, weld steel plates at the edge of the hammer or increase or decrease concrete to balance it to prevent the tamping pit from tilting.
6.夯击时,落锤应保持平稳,夯位正确。如错位或坑底倾斜度过大,应及时将坑整平,予以补夯后方可进行下一道工序。
6. When tamping, the falling hammer shall be kept stable and the tamping position shall be correct. If the pit bottom is misaligned or tilted too much, the pit should be leveled in time and the next process can be carried out only after it is tamped.
强夯时,会对地基及周围建筑物产生一定的振动,夯击点宜距现有建筑物15米以上,如间距不足,可在夯点与建筑物之间开挖隔振沟带,其沟深度要超过建筑物的基础深度,并有足够的长度,或把强夯场地包围起来。更多相关信息就来网站http://www.sddhfjx.cn获取吧。
During dynamic compaction, certain vibration will be produced to the foundation and surrounding buildings. The compaction point should be more than 15 meters away from the existing buildings. If the spacing is insufficient, a vibration isolation ditch belt can be excavated between the compaction point and the buildings. The depth of the ditch should exceed the foundation depth of the buildings, and there should be enough length, or the dynamic compaction site should be surrounded.
