Cast-in-place pile construction method adopting YKP construction method and manufactured cast-in-place pile
The invention discloses a YKP construction method cast-in-place pile construction method and a manufactured cast-in-place pile, and belongs to the technical field of pile foundations. According to the YKP construction method cast-in-place pile construction method, the outer pile casing is pressed into the soil body in a static pressure mode to form the pile hole, the inner sleeve is used for pressing the extruded and expanded concrete input into the outer pile casing into the soil body to form the concrete expanded body, and meanwhile the expanded body reinforcing piece is pressed into the concrete expanded body to form the rigid concrete expanded head; and then a reinforcement cage assembly is placed in the outer pile casing, concrete is poured, the outer pile casing is pulled out after initial setting of the concrete, and meanwhile, backlash concrete is filled through a grouting pipe to form a cement soil outer ring layer. The problems that an existing construction method is large in noise and serious in environmental pollution are solved, the problems that the hole wall is free of collapse, sediment, necking down and the like, and the quality is influenced are solved, and the pile body quality is reliable. The cement soil outer ring layer is arranged on the outer side of the pile body of the formed cast-in-place pile, so that friction resistance between the pile and soil on the pile side is greatly increased, the rigid concrete expansion head is arranged, and the bearing capacity of the cast-in-place pile is effectively improved.
本发明公开了一种YKP工法灌注桩施工方法及制作的灌注桩，属于桩基技术领域。本发明的YKP工法灌注桩施工方法，通过静压方式将外护筒压入土体中形成桩孔，并利用内套筒将输入外护筒内的挤扩混凝土压入土体中形成混凝土扩大体，同时压入扩大体加强件形成刚性混凝土扩大头，之后在外护筒内放入钢筋笼组合件并浇筑混凝土，混凝土初凝后拔出外护筒，同时通过注浆管充填侧隙混凝土形成水泥土外圈层。解决了现有施工方法噪音大、环境污染严重的问题，孔壁无坍塌、无沉渣，也无缩颈等影响质量的问题存在，桩身质量可靠；形成的灌注桩在桩身外侧具有水泥土外圈层，使得桩与桩侧土体摩擦阻力大大增加，且具有刚性混凝土扩大头，有效提高了灌注桩的承载力。
