Ultra-long rotary excavating cast-in-place pile and construction method thereof
The invention discloses an ultra-long rotary excavating cast-in-place pile, belongs to the technical field of building construction, and solves the problems that in the prior art, a rotary excavatingcast-in-place pile is prone to collapse, sundries are prone to entering the bottom of a pile hole, and sediment cannot be cleared away. The ultra-long rotary excavating cast-in-place pile comprises arotary excavating cast-in-place pile body, a pile casing is arranged in the rotary excavating cast-in-place pile body, a reinforcement cage is arranged on the inner wall of the pile casing, and slurryis injected into the pile casing. By the adoption of the scheme, the pile casing is arranged to serve as a pore-forming protection arm of the rotary excavating cast-in-place pile, soil is taken in the pile casing for pore forming through a rotary excavating machine, collapse can be effectively avoided, sundries are prevented from entering the pile hole, the final slag removing speed is high, theslurry is adopted for arm protection, the water level in the pile hole can be stabilized, drilling slag can be conveniently carried, and hole collapse is effectively prevented.
本发明公开了一种超长旋挖灌注桩，属于建筑施工技术领域，解决了现有技术中旋挖灌注桩容易造成坍塌及容易造成杂物进入桩孔底部、沉渣无法清楚干净的问题，其包括旋挖灌桩本体，所述旋挖灌装本体内设置有护筒，所述护筒的内壁设置有钢筋笼，所述护筒内注入有泥浆；采用上述方案，设置护筒作为旋挖灌注桩的成孔护臂，利用旋挖机在护筒内取土成孔，能够有效避免出现坍塌，防止杂物进入桩孔，使得最终清渣速度块，采用泥浆进行护臂，可以稳定桩孔内水位、便于挟带钻渣，有效的防止桩孔出现塌孔的现象。
