Stiffness expansion pile construction method
The invention discloses a reinforced expansion pile construction method, which belongs to the technical field of reinforced expansion pile construction, and comprises the following steps: S1, measuring and setting out to determine the center of a reinforced expansion pile position; s2, drilling holes by a drilling machine and taking out all underground in-situ soil; s3, outer pile body construction; s4, constructing a composite pile body; s5, expanding head construction; and S6, hydrophobic cement soil is injected into the expansion head to complete filler sealing, and the reinforced expansion pile construction is completed. The cement soil added in the construction process of the outer pile body and the expanded head contains the porous beads with the surfaces coated with the sealant and the interior storing the hydrophobic modifier, hydration of the concrete cannot be affected, and the hydrophobicity of the outer pile body and the expanded head can be improved after the outer pile body and the expanded head are formed; the outer pile body and the expansion head are prevented from being eroded by underground moisture, and the service life of the reinforced expansion pile is prolonged.
本发明公开了一种劲扩桩施工方法，属于劲扩桩施工技术领域，包括以下步骤：S1：测量放样确定劲扩桩桩位中心；S2：钻机钻孔并取出全部地下原位土；S3：外桩身施工；S4：复合桩身施工；S5：扩大头施工；S6：将疏水性水泥土注入扩大头内完成填料封闭，劲扩桩施工完成；本发明在外桩身和扩大头施工过程中加入的水泥土中包含有表面包覆有密封剂且内部储存有疏水改性剂的带孔洞珠体，其不仅不会影响混凝土的水化，而且能够在外桩身和扩大头成型后提高其疏水性，避免地下水分侵蚀外桩身和扩大头，提高劲扩桩的使用年限。
