It is particularly important to choose the construction treatment plan in the project construction, because the soil conditions of each site are different, and taking too simple methods will fail to achieve the consequences of reinforcement, which will easily lead to the weak foundation and even significant soil loosening, especially the pressure of large equipment. The surface is very easy to deform and the quality will be seriously damaged. Dynamic consolidation method, also known as dynamic consolidation method. A large crawler crane is used to drop a heavy hammer of 8-40 tons freely from a height of 6-40 meters to strongly tamp the soil. It is suitable for artificial fill, collapsible soil and loess. If the technique and method of dynamic compaction are adopted for construction, the road surface can be quickly reinforced completely, and the compressive ability and bearing ability of the foundation can be obviously strengthened, so that the foundation can be very firm. Dynamic compaction is widely used in foundation treatment, which is characterized by green environmental protection, good reinforcement consequences and simple operation. Dynamic compaction has high practicability in foundation treatment and has no impact on other aspects. Industrial enterprises will produce a lot of waste residue in production, which will do great harm to the environment. If it is handled, it will take more time and a lot of cost. If these waste residues are used as the raw materials in the dynamic compaction foundation to fill the foundation, it will be an environmentally friendly and economical method, which may reduce the amount of industrial waste, make the urban environment better, and be conducive to the forward development of science and technology. Therefore, dynamic compaction foundation treatment is particularly environmentally friendly.


建设名目通常预估消耗的能源要比实际须要的量大,这样就会挥霍掉很多。强夯地基用起重机械将大吨位夯锤起吊到6-30m高度后,自由落下,给地基土以强大的冲击的夯击,使土中出现冲击波和很大的冲击应力,迫使土层空隙压缩,土体局部液化,在夯击点周围产生裂隙,形成良好的排水通道,孔隙水和气体逸出。强夯机租赁价格基坑的夯实范围应大于基础底面。开挖时,基坑每边比设计宽度加宽不宜小于0.3米,以便于夯实工作的进行,基坑边坡适度放缓。夯实前,基坑底面应高出设计标高,预留土层的厚度可为试夯时的总下沉量加50至100毫米。夯实完毕,将基坑表面拍实至设计标高。强夯地基处理技巧能杜绝这种景象,在施工处理进程中,所用到的填料很少。而且填料的类型来源十分便利,能充分用到周边的沾染物质。这样就明显进步了节能减排的效力。
Construction projects usually estimate that the energy consumption is greater than the actual demand, which will waste a lot. After the heavy-duty rammer is lifted to a height of 6-30m by the lifting machine for dynamic compaction of the foundation, it will fall freely to tamp the foundation soil with strong impact, resulting in shock wave and great impact stress in the soil, forcing the gap of the soil layer to compress, local liquefaction of the soil, cracks around the tamping point, forming a good drainage channel, and pore water and gas escape. The rental price of dynamic compactor the tamping range of foundation pit shall be greater than the bottom surface of foundation. During excavation, the width of each side of the foundation pit shall not be less than 0.3m wider than the design width, so as to facilitate the compaction work, and the slope of the foundation pit shall be moderately slowed down. Before compaction, the bottom of the foundation pit shall be higher than the design elevation, and the thickness of the reserved soil layer can be the total settlement during trial compaction plus 50 to 100 mm. After compaction, the surface of the foundation pit shall be compacted to the design elevation. Dynamic compaction foundation treatment technology can eliminate this phenomenon, and few fillers are used in the construction treatment process. Moreover, the type and source of filler are very convenient, and the surrounding contaminated substances can be fully used. This has significantly improved the effectiveness of energy conservation and emission reduction.
强夯地基处理之前,要具体计划工程的施工时光盘算。若名目时光请求紧,应用强夯施工的方法能很大水平的缩短处理工期,而且可能高品质的实现全部强夯工程。因此强夯技巧受到了大力地推广。
Before dynamic compaction foundation treatment, the construction time of the project shall be specifically planned. If the name and time are tight, the application of dynamic compaction construction method can greatly shorten the treatment period, and may realize all dynamic compaction projects with high quality. Therefore, the dynamic compaction technique has been vigorously promoted.
