Rapid curing construction method for hollow pile section slurry of cast-in-place pile
The invention relates to the technical field of cast-in-place pile construction, and discloses a rapid curing construction method for slurry of an empty pile section of a cast-in-place pile. A cast-in-place pile is constructed and formed, an empty pile section is arranged above the cast-in-place pile, and slurry is contained in the empty pile section; slurry in the upper portion of the empty pile section is pumped out through a slurry pump; the hollow pile section is filled with construction muck, the construction muck is mixed with slurry in the hollow pile section, and slurry muck is formed; a stirring drill rod is arranged in an empty pile section, a stirring drill bit is arranged at the bottom of the stirring drill rod, in the process that the stirring drill rod drives the stirring drill bit to conduct synchronous stirring in the empty pile section, solidified slurry and high-pressure gas are sprayed out to the slurry residue soil in the empty pile section, the solidified slurry and the slurry residue soil are stirred and mixed till the slurry residue soil in the empty pile section is solidified, and then the solidified slurry is solidified. And a solidified pile section located above the cast-in-place pile is formed. The slurry muck is rapidly solidified by spraying high-pressure gas and solidifying slurry, the strength of undisturbed soil can be achieved in a short time, and then normal walking of mechanical equipment in a construction site is guaranteed.
本发明涉及灌注桩施工的技术领域，公开了灌注桩空桩段泥浆的快速固化施工方法，包括以下施工步骤；施工成型灌注桩，灌注桩的上方具有空桩段，空桩段中具有泥浆；利用泥浆泵将空桩段的上部中的泥浆抽出；将施工渣土填充进空桩段中，与空桩段中的泥浆混合，形成泥浆渣土；将搅拌钻杆置于空桩段中，搅拌钻杆的底部设有搅拌钻头，搅拌钻杆带动搅拌钻头在空桩段中同步搅拌的过程中，向空桩段中的泥浆渣土喷出固化浆液以及高压气体，固化浆液与泥浆渣土搅拌混合，直至空桩段中的泥浆渣土固化后，形成位于灌注桩上方的固化桩段。通过喷出高压气体以及固化浆液使泥浆渣土快速固化，在短时间内可以达到原状土的强度，进而保证施工场地机械设备正常行走。
