Monitoring and analyzing method for blanking construction of vibration immersed tube gravel pile
The invention relates to a monitoring and analyzing method for blanking construction of a vibration immersed tube gravel pile, which comprises the following steps of: a first testing stage: arranging a testing device before construction, which comprises a pile bottom pressure monitoring mechanism, an inner wall pressure measuring mechanism and a pore pressure meter mechanism; pile pipe pile sinking construction is conducted according to the normal vibration pipe sinking pile forming technological process, and the bottom end pressure of a pile pipe is obtained through measurement of a bottom pressure meter; the pile pipe is backfilled with dry gravel materials and filled with water, and the distribution condition of lateral pressure borne by the inner wall of the pile pipe when the gravel materials are completely blocked and cannot be discharged in the water-free state and the water state in the pile pipe is obtained; and a second testing stage: arranging a testing device before construction, performing construction according to a normal vibration immersed tube pile forming process flow, and performing various tests in the construction process: monitoring and analyzing the gravel blanking condition by obtaining measurement data, including monitoring and analyzing the blanking difficulty of the gravel, and performing the monitoring and analysis on the discharging condition of the gravel. And judging whether the broken stone material is blocked and is difficult to discharge or not, and judging the main reason of blocking.
本发明涉及一种振动沉管碎石桩下料施工的监测分析方法，包括：第一测试阶段：在施工前设置好测试装置，包括桩底压力监测机构、内壁压力测量机构和孔压计机构；按照正常振动沉管成桩工艺流程进行桩管沉桩施工，底部压力计测量得到桩管的底端压力；在桩管内回填干碎石料并灌水，得到桩管内在无水状态和有水状态下碎石料完全堵住不能下料时桩管内壁受到的侧向压力的分布情况；第二测试阶段：在施工前设置好测试装置，按照正常振动沉管成桩工艺流程进行施工，在施工过程中进行各项测试：通过获得测量数据，对碎石下料情况进行监测分析，包括碎石料的下料困难监测分析，判断碎石料中是否出现堵住而难以下料的问题，以及判断出现堵住的主要原因。
