The invention discloses a fabricated core-carrying pile and a construction method. The core-carrying pile is composed of solidified soil on the outer side and a prefabricated pile serving as a core. The solidified soil is in a flow state in the initial stage, and the solidified soil adheres to the outer surface of the prefabricated pile after solidification to form a columnar shape; the unconfinedcompressive strength of the solidified soil is larger than or equal to 1 MPa; the slump of the solidified soil is smaller than 2 cm; when the prefabricated pile is inserted into the flow-state solidified soil, the flow-state solidified soil flows upwards along the outer surface of the prefabricated pile; and foundation soil wraps and cements the solidified soil. The fabricated core-carrying pilehas the social benefits of being green, environmentally friendly, safe and reliable, can reduce the manufacturing cost and shorten construction period, and has great economic value.
本发明公开了一种装配式载芯桩与施工方法，其载芯桩是由外侧的固化土和内芯的预制桩组成；固化土初期呈流态，凝固后胶结在预制桩的外表面形成柱状；固化土的无侧限抗压强度大于等于1MPa；固化土的塌落度小于2cm；在流态固化土中插入预制桩时，流态固化土沿预制桩外表向上流动；地基土包裹着固化土并胶结于一起。该专利具有绿色、环保和安全可靠的社会效益，同时能降低造价和缩短工期，具有重大的经济价值。
