Vibroflotation compaction method for pipeline backfill construction
The invention discloses a vibroflotation compaction method for pipeline backfill construction. The vibroflotation compaction method comprises the steps that 1, a test plot is selected, a construction site is cleaned and leveled, point locations are measured and placed through a GPS, the point locations are arranged in a regular triangle mode, and the distance between every two point locations is 2m or 1.5m; 2, a vibroflotation device is installed on a crane and aligned with vibroflotation points; 3, the crane and the vibroflotation device are started, the vibroflotation device sinks rapidly, and the pore forming speed is controlled to range from 2m/min to 2.5m/min; 4, when the vibroflotation device sinks to the preset compaction depth, the water injection amount is reduced to the minimum, vibration is reserved for 10-20s at the depth, and then the vibroflotation device is lifted at a constant speed; 5, the vibroflotation device is lifted at the speed of 1.5-2m/min, and vibration is reserved for 10-20s every time the vibroflotation device is lifted by 0.5m; and 6, after construction of the current point location is completed, shutdown, water shut-off and machine moving positioning operation is conducted, and the steps 2-5 are repeated on another vibroflotation point for construction till construction of the whole test plot is completed. According to the vibroflotation compaction method, after vibroflotation parameters are determined through tests, construction is conducted comprehensively, and the construction quality is guaranteed.
本发明公开了一种用于管线回填施工的振冲密实方法，步骤一，选取试验地块，清理平整施工场地，用GPS测放点位，点位按正三角形布置，间距2米或1.5米；步骤二，将振冲器安装在吊机上，使振冲器对准振冲点；步骤三，启动吊机和振冲器，振冲器快速下沉，造孔速度控制在2m/min～2.5m/min；步骤四，当振冲器下沉到预设密实深度时，将射水量减至最小，并在这一深度上留振10～20s，然后匀速提升振冲器；步骤五，以1.5m/min～2m/min速度提升振冲器，每提升0.5m就留振10～20s；步骤六，完成当前点位施工后，进行关机、关水和移机定位操作，在另一个振冲点上重复上述步骤二‑五进行施工，直至整个试验地块完成施工。本发明通过试验确定振冲参数后，再全面铺开施工，保证施工质量。
