High-strength secant pile construction method
The invention relates to the technical field of secant piles, and discloses a high-strength secant pile construction method, which comprises the following steps of: 1) constructing a plurality of cast-in-place piles on a construction site by adopting a rotary drilling rig, forming meat piles by the cast-in-place piles, and forming plain pile intervals between adjacent cast-in-place piles; (2) the drilling machine platform is moved to a plain pile interval; (3) a power head drives a stirring drill rod to rotate, the stirring drill rod downwards drills into the soil body along the plain pile interval, and solidified slurry and high-pressure air are sprayed into the soil body; (4) the soil body and the solidified slurry are mixed and solidified to form a stirring pile, the stirring pile forms a plain pile, and the stirring pile is engaged with the adjacent cast-in-place pile to form an engaged pile; soil bodies in gaps of plain piles are stirred and solidified slurry is sprayed through a stirring drill rod and a stirring drill bit of the rotary drilling rig, so that the soil bodies and the solidified slurry are fully mixed and solidified to form stirring piles, and the stirring drill bit can spray high-pressure air while spraying the solidified slurry, so that the mixing effect of the soil bodies and the solidified slurry is improved.
本发明涉及咬合桩的技术领域，公开了高强咬合桩施工方法，1)、采用旋挖钻机在施工场地施工多个灌注桩，灌注桩形成荤桩，相邻的灌注桩之间具有素桩间隔；2)、将钻机平台移动至素桩间隔；3)、动力头驱动搅拌钻杆转动，搅拌钻头沿着素桩间隔朝下钻进土体，往土体中喷射固化浆液以及高压空气；4)、土体与固化浆液混合固化形成搅拌桩，搅拌桩形成素桩，搅拌桩与相邻的灌注桩咬合，形成咬合桩；通过旋挖钻机的搅拌钻杆与搅拌钻头对素桩间隔中的土体搅拌并喷射固化浆液，使得土体与固化浆液充分混合固化形成搅拌桩，并且搅拌钻头在喷射固化浆液的同时还会喷射高压空气，以便提高土体与固化浆液混合效果。
