Premixed flow-state solidified soil stiffening core pile, composite pile and construction method of pre-mixed flow-state solidified soil stiffening core pile and composite pile
The invention discloses a premixed flow-state solidified soil stiffening core pile, a combined pile and a construction method of the premixed flow-state solidified soil stiffening core pile, and the premixed flow-state solidified soil stiffening core pile comprises a preformed hole, a pouring material and a preformed pile which are processed on foundation soil; the depth of the preformed hole is smaller than or equal to the length of the preformed pile; the preformed holes are filled with pouring materials, and the pouring materials adopt premixed flow state solidified soil with different strengths; the volume of the pouring material is not less than 1.5 times of the difference between the theoretical volume of the preformed hole and the volume of the preformed pile, or the volume of the pouring material is equal to the theoretical volume of the preformed hole; the prefabricated pile is installed in the prefabricated hole, and the bottom of the prefabricated pile can be located above the inner bottom face of the prefabricated hole and can also penetrate through the inner bottom face of the prefabricated hole to go deep into foundation soil. The bearing performance and stability of the stiffening core pile and the composite pile can be improved.
本发明公开了一种预拌流态固化土劲芯桩、组合桩及其施工方法，所述预拌流态固化土劲芯桩，包括：在地基土上加工的预成孔、灌注料及预制桩；所述预成孔的深度小于或等于预制桩的长度；所述预成孔填充有灌注料，灌注料采用不同强度的预拌流态固化土；灌注料的体积不少于所述预成孔的理论体积与预制桩体积差的1.5倍，或灌注料的体积与预成孔的理论体积相等；所述预制桩安装在所述预成孔内，预制桩的底部可位于预成孔内底面的上方，也可穿过预成孔的内底面，深入到地基土内。本发明能够提高劲芯桩和组合桩的承载性能及稳定性。
