强夯租赁时间选择多长合适?强夯租赁告诉你强夯法指的是为进步脆弱地基的承载力,强夯租赁用重锤自一定高度下落夯击土层使地基疾速固结的办法。其又称动力固结法,应用起吊设备,将10~40吨的重锤提升10~40米高处使其自在下落,依托强大的夯击能和冲击波作用夯实土层。强夯法主要用于砂性土、非饱和粘性土与杂填土地基。
How long is the dynamic compaction lease suitable? The dynamic compaction lease tells you that the dynamic compaction method refers to the method that the heavy hammer falls from a certain height to compact the soil layer to consolidate the foundation quickly in order to improve the bearing capacity of the fragile foundation. It is also called dynamic consolidation method. The lifting equipment is used to lift the 10 ~ 40 ton hammer to a height of 10 ~ 40 meters to make it fall freely, and the soil layer is compacted by relying on the powerful tamping energy and shock wave. Dynamic compaction method is mainly used for sandy soil, unsaturated cohesive soil and miscellaneous fill foundation.
夯法加固原理如下:土是由固体颗粒,水和气体三局部组成的三项体系。土体在重锤的作用下将土体中气体排出,在夯点四周呈现径向裂痕,构成软土中空隙水的浸透通道,为超静水压力的消散发明了条件,相当大的夯击能转化为土体的紧缩变形,随夯击能积聚,土体强度取得进步。
The principle of consolidation by tamping method is as follows: soil is a three item system composed of solid particles, water and gas. Under the action of the heavy hammer, the air in the soil is discharged, and radial cracks appear around the tamping point, forming the infiltration channel of void water in the soft soil, creating conditions for the dissipation of excess hydrostatic pressure. Considerable tamping energy is transformed into the contraction deformation of the soil. With the accumulation of tamping energy, the soil strength is improved.
施工中测夯击沉量比测土中水压力简单,普通在工程中以夯击数和夯沉量关系曲线肯定击能,有经历的工程师也可直接从夯坑四周空中隆起水平判别。
The measurement of tamping settlement is simpler than the measurement of water pressure in soil during construction. Generally, the impact energy is determined by the relationship curve between tamping number and tamping settlement in the project. Experienced engineers can also directly judge the uplift level in the air around the tamping pit.
夯点布置及夯点间距:夯击点可按方形或梅花形布置。强夯租赁告诉你夯点间距要远,使得深层土得到加固,然后中间补插副夯点。强夯设备告诉你夯点间距通常是~米,思索到地基的应力扩散作用,夯点布置范围则宜比根底范围大H/(其中H为加固的深度)。当土质差、软土层厚时应恰当加大夯点间距,增加夯实遍数到达加固目的,当软土层较薄而有砂类土夹层或土夹石填土时可恰当减小夯距。
Layout and spacing of tamping points: tamping points can be arranged in square or plum shape. The dynamic compaction lease tells you that the compaction points should be far away, so that the deep soil can be reinforced, and then the secondary compaction points are inserted in the middle. The dynamic compaction equipment tells you that the spacing between compaction points is usually ~ M. considering the stress diffusion effect of the foundation, the arrangement range of compaction points should be h/ (where h is the reinforcement depth) larger than the foundation range. When the soil is poor and the soft soil layer is thick, the tamping point spacing shall be properly increased and the tamping times shall be increased to achieve the purpose of reinforcement. When the soft soil layer is thin and there is sand soil interlayer or soil mixed with stone fill, the tamping distance can be properly reduced.
