Large-diameter ultra-deep cast-in-place pile SCS system hole cleaning construction method
The invention relates to the technical field of hole cleaning equipment, and discloses a large-diameter ultra-deep cast-in-place pile SCS system hole cleaning construction method which comprises the following construction steps that (1) an SCS hole cleaning system is moved to a construction position through a crawler crane; (2) the SCS hole cleaning system lowers the SCS submerged cement slurry treatment end into the pile position hole to start primary hole cleaning; (3) a load detection device for monitoring the load of the SCS submersible cement slurry treatment end in real time is arranged on the SCS submersible cement slurry treatment end; the SCS hole cleaning system sprays low-concentration slurry to the high-concentration slurry in the pile position hole by lowering the SCS submerged cement slurry treatment end to dilute the low-concentration slurry to form mixed slurry, and then the mixed slurry is discharged to the slurry separation treatment equipment through the sludge discharge pipe to separate the slurry from the muck; the load detection device is used for monitoring the load of the SCS submerged cement slurry treatment end in real time, it is avoided that the SCS submerged cement slurry treatment end is too deep in a pile position hole to affect discharging of pumped mixed slurry, and the problem that the hole cleaning efficiency of a large-diameter ultra-deep pile and an expanded bore pile is low is solved.
本发明涉及清孔设备的技术领域，公开了大直径超深灌注桩SCS系统清孔施工方法，包括以下施工步骤：1)、通过履带吊机将SCS清孔系统移至施工位上；2)、SCS清孔系统将SCS潜水泥渣处理端头往桩位孔内下放开始一次清孔；3)、SCS潜水泥渣处理端头上设有实时监控SCS潜水泥渣处理端头荷载的负载检测装置；SCS清孔系统通过下放SCS潜水泥渣处理端头对桩位孔内的高浓度泥浆喷射低浓度泥浆稀释形成混合体泥浆，再通过排泥管将混合体泥浆排至泥浆分离处理设备分离浆液与渣土；利用负载检测装置实时监控SCS潜水泥渣处理端头的荷载，避免SCS潜水泥渣处理端头处于桩位孔内过深影响抽取混合体泥浆的排出，解决了大直径超深桩及扩底桩的清孔效率低的问题。
