High-strength solidified soil mixing pile construction equipment for replacing secant pile concrete plain pile
The invention relates to the technical field of mixing pile construction equipment, and discloses high-strength solidified soil mixing pile construction equipment for replacing a secant pile concrete plain pile, which comprises a drilling machine platform arranged on a plain pile construction position, and the drilling machine platform is provided with a power head and a mixing drill rod clamped by the power head to rotate. The bottom of the stirring drill rod is provided with a stirring drill bit which downwards drills into a soil body at a plain pile construction position, and the bottom of the stirring drill bit is provided with a slurry outlet for spraying out solidified slurry and a gas outlet for spraying out high-pressure gas; a soil body in a plain pile construction position is cut, scattered and stirred through a stirring drill rod and a stirring drill bit of a rotary drilling rig, then solidified slurry and high-pressure air are jetted through the stirring drill bit, and the soil body and the solidified slurry are fully mixed and solidified to form a plain pile. And the stirring drill bit sprays high-pressure air so that the stirring and mixing effect of the soil body and the solidified slurry can be further improved, and the problems that the strength of a pile body of the jet grouting pile is obviously low, the quality is poor, the integrity is poor, and leakage is prone to occurring are solved.
本发明涉及搅拌桩施工设备的技术领域，公开了代替咬合桩混凝土素桩的高强固化土搅拌桩施工设备，包括布置在素桩施工位上的钻机平台，钻机平台上设有动力头以及由动力头夹持转动的搅拌钻杆，搅拌钻杆的底部设有在素桩施工位朝下钻进土体的搅拌钻头，搅拌钻头的底部设有供固化浆液喷出的出浆口以及供高压气体喷出的出气口；通过旋挖钻机的搅拌钻杆与搅拌钻头对素桩施工位中的土体切割打散并搅拌，再通过搅拌钻头喷射固化浆液以及喷射高压空气，土体与固化浆液通过充分混合固化形成素桩，而搅拌钻头喷射高压空气可以让土体与固化浆液进一步的提高搅拌混合效果，解决了旋喷桩桩身强度明显较低且质量较差，完整性较差，容易渗漏的问题。
