Method for treating screen residue backfill soil foundation through pneumatic vibration rod compaction method
The invention discloses a method for treating a screen residue backfill soil foundation through a pneumatic vibration rod compaction method. The method comprises the following steps that 1, backfill data are determined; step 2, gas vibration sinking; step 3, primary vibration retention; 4, the vibration point position A is backfilled; 5, secondary pneumatic compaction is carried out; step 6, carrying out secondary vibration retention; step 7, repeating secondary pneumatic compaction and residual vibration; step 8, backfilling the vibration pressing point position A; and 9, the vibration rod is moved to the next vibration point position. High-pressure gas jet and excitation force generated by the pneumatic vibration rod jointly act on the screen residue backfill soil, the high-pressure gas jet and vibration waves drive large and small soil particles in the soil body to be continuously rearranged and mutually filled to achieve a stable structure, and compaction of the soil body is achieved. According to the content of coarse particles in the screen residue backfill soil and the backfill depth, the air injection pressure, the vibration remaining time and the filler air vibration reverse insertion frequency of the pneumatic vibration rod compaction method can be dynamically adjusted, and the screen residue backfill soil foundation treatment method is green, economical and easy and convenient to construct.
本发明公开了一种气动振杆密实法处理筛余回填土地基的方法，包括以下步骤1、确定回填数据；步骤2、气振下沉；步骤3、一次留振；步骤4、回填振动点位A；步骤5、二次气动振实；步骤6、二次留振；步骤7、重复二次气动振实与留振；步骤8、回填振压点位A；步骤9、将振杆移动至下一个振动点位。本申请利用气动振杆产生的高压气体射流和激振力联合作用于筛余回填土，高压气体射流和振动波驱动土体内部大小土颗粒不断重新排列，相互填充达到稳定结构，实现土体的密实。本发明可以根据筛余回填土内部粗颗粒含量和回填深度，动态调整气动振杆密实法的喷气压力、留振时间和填料气振反插次数，是一种绿色经济，且施工简单方便的筛余回填土地基处理方法。
