Construction method for rapidly tamping foundation through hydraulic pressure
The invention relates to a construction method for rapidly tamping a foundation through hydraulic pressure. The construction method comprises the steps that S1, surveying and setting out are conducted, a gradienter is used for calibration, tamping points and tamping parameters are set, hydraulic equipment is in place, and the tamping parameters comprise weight of a hydraulic hammer, diameter R0 of the bottom face of the hydraulic hammer and falling distance L;S2, tamping is conducted, specifically, according to the set tamping point, the hydraulic hammer is aligned with the tamping point to conduct tamping, during tamping, starting of a plurality of motors is controlled according to the bottom surface diameter adjusting amount of the hydraulic hammer, and running time of the motors is controlled according to ground base surface hardness so as to adjust tamping parameters;S3, a rammed pit is filled and leveled up through a bulldozer;S4, full compaction is conducted, the hydraulic hammer is utilized to loosen soil and compact the soil on the surface layer of a field; therefore, the tamping parameters in the tamping process can be accurately adjusted through feedback pressure of the hydraulic hammer, tamping descending depth and descending distance, then the tamping process can be completed in one step, tamping in-place inspection does not need to be conducted, and time cost and economic cost are effectively saved.
本发明涉及一种运用液压快速夯实地基的施工方法，包括：步骤S1，测量放线，利用水平仪校准，设置夯实点和夯实参数，液压设备就位，夯实参数包括液压锤重量、液压锤底面直径R0和落距L；步骤S2，夯实，根据设置好的夯实点将液压锤对准夯实点进行夯实，在进行夯实时，根据液压锤底面直径调节量控制多个电机的启动，根据地基底面硬度控制多个电机的运行时间以对夯实参数进行调节；步骤S3，用推土机将夯坑填平；步骤S4，满夯，利用液压锤将场地表层松土夯实；从而能够通过液压锤反馈压力、夯实下降深度和落距对夯实过程中的夯实参数进行精确调节，进而能够在夯实的过程中一步到位，无需进行夯实到位检验，有效节省了时间成本和经济成本。
