Dynamic compaction machine is widely used in construction projects and reclamation projects, followed by the renewal of equipment, which strengthens the role of leasing industry. Dynamic compaction machine replacement is a method of dynamic compaction used to reinforce saturated soft clay foundation. In the process of dynamic compaction replacement, the soil structure is damaged, and the foundation soil produces excess pore water pressure. However, with the increase of time, the structural strength of soil will be restored, and the granular material will be recycled Generally, piers have good water permeability, which is conducive to the dissipation of excess pore water pressure and consolidation.
在通过分层强夯建造高填方路堤的过程中,可以使用起重能力超过15吨的多根电缆或起重能力超过20度的单缆履带起重机来配合和协助桅杆对于联合合作,例如多绳起重机应与自动解耦设备配合使用,并确保夯锤的较大前移高度为15米。
In the process of constructing high fill embankment by layered dynamic compaction, multiple cables with lifting capacity of more than 15 tons or single cable crawler crane with lifting capacity of more than 20 degrees can be used to cooperate with and assist the mast. For joint cooperation, for example, multi rope crane should be used with automatic decoupling equipment, and the larger forward moving height of rammer should be 15 meters.
在分层动态压实施工的实施中,一层强夯的高度从8-12米的填充高度开始,小于此高度的一层填充不使用动态压实,并且上部路堤填充8Mi会进行动态压实,直到到达路堤顶部为止。
In the implementation of layered dynamic compaction construction, the height of a layer of dynamic compaction starts from the filling height of 8-12m, and the layer less than this height does not use dynamic compaction, and the upper embankment filling 8mi will carry out dynamic compaction until it reaches the top of the embankment.
强夯机的夯锤应为具有较高弹性模量的圆柱形钢夯,或为将钢筋混凝土浇注在厚钢外壳中的圆柱形夯,夯锤的重量为10 吨,在其夯锤的底部,应对称设置与顶部表面相连的4-6个通风孔,以便夯锤可以在提起锤子时清洁底部的空气并减少坑底部的吸力。
The rammer of dynamic compaction machine shall be cylindrical steel rammer with high elastic modulus, or cylindrical rammer pouring reinforced concrete into thick steel shell. The weight of the rammer is 10 tons. At the bottom of the rammer, 4-6 ventilation holes connected with the top surface shall be symmetrically set, so that the air at the bottom of the rammer can be cleaned and the suction at the bottom of the pit can be reduced when lifting the hammer.
