Method for controlling launching of vibro-replacement stone column machine
The invention discloses a launching control method of a vibro-replacement gravel pile machine, the vibro-replacement gravel pile machine comprises a vibro-replacement device, and the launching control method comprises the following steps: enabling a pipeline for supplying launching water to penetrate through a telescopic guide rod and the vibro-replacement device and then extend out of the bottom end of the vibro-replacement device, so that the launching water is sprayed out of the bottom end of the vibro-replacement device to carry out water-flushing pre-damage on a stratum; in the vibroflotation construction process, the vibroflotation speed of a vibroflotation device and the current water drainage pressure are obtained; comparing the obtained vibroflotation speed with a vibroflotation speed threshold value; and according to a comparison result of the obtained vibroflotation speed and the vibroflotation speed threshold value, controlling the flow of the discharged water supplied to the discharged water so as to adjust the current discharged water pressure, so that the vibroflotation construction is completed by utilizing the vibroflotation of the vibroflotation device and the adjusted current discharged water pressure. The supply quantity of the water pressure is accurately controlled according to the vibroflotation speed and the compactness of different stratums, so that the vibroflotation construction of the deep and thick covering layer stratums of more than 50m is smoothly carried out, the failure rate is reduced, and the economic loss is reduced.
本发明公开了一种振冲碎石桩机的下水控制方法，所述振冲碎石桩机包括振冲器，包括：将用于供应下水的管道穿过伸缩导杆和振冲器后从振冲器的底端伸出，以便下水从振冲器底端喷出对地层进行水冲预破坏；在振冲施工过程中获取振冲器的振冲速度、以及当前下水压力；将所获取的振冲速度与振冲速度阈值进行比较；根据所获取的振冲速度与振冲速度阈值的比较结果，控制供应下水的下水流量，从而调整当前下水压力，以便利用振冲器振冲和调整后的当前下水压力完成振冲施工。本发明根据振冲速度和不同地层密实度精确控制下水压力的供给量，使50m以上深厚覆盖层地层振冲施工顺利进行，降低失败率，减少经济损失。
