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 telescopic guide rod and a vibro-replacement device, and the launching control method comprises the steps that a pipeline used for supplying launching water penetrates through the telescopic guide rod and the vibro-replacement device and then extends 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 conduct water flushing pre-damage on a stratum; the current stratum compactness is obtained in the vibroflotation construction process; obtaining the instantaneous drainage pressure of the supplied drainage, and determining the obtained instantaneous drainage pressure as the current drainage pressure; according to the corresponding relation between the preset drainage pressure and the stratum compactness, the target drainage pressure corresponding to the current stratum compactness is searched for; and controlling the water discharge flow of the supplied water to enable the current water discharge pressure to reach the target water discharge pressure, so that the vibroflot construction is completed by using the vibroflot and the target water discharge pressure. According to the method, the supply quantity of the water pressure is accurately controlled according to different stratum compactness, so that the stratum vibroflotation construction of the deep and thick covering layer 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伸缩导杆和振冲器，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当前地层密实度；获取供应下水的瞬时下水压力，并将获取的瞬时下水压力确定为当前下水压力；根据预置的下水压力与地层密实度的对应关系，查找与当前地层密实度相对应的目标下水压力；控制供应下水的下水流量，使当前下水压力达到目标下水压力，以便利用振冲器和目标下水压力完成振冲施工。本发明根据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。
