Prefabricated pedestal pile construction method, automatic construction method and prefabricated pedestal pile
The invention discloses a prefabricated pedestal pile construction method, an automatic construction method and a prefabricated pedestal pile. The construction method comprises the following steps that S1, equipment enters a site; s2, putting down a pile body; s3, first-order filler compaction is conducted, specifically, first-order filler is put into the extension pipe in batches, and a first-order compact body is formed through compaction with an extrusion hammer; s4, second-order filler compaction is conducted, specifically, a second-order compact body wrapping the extension pipe is formed through compaction, or a compaction barrel compacted in the extension pipe and a final-order compact body wrapping the bottom end of the extension pipe are formed through compaction; and S6, inner pile forming. According to the construction method, the sinking probability of the second-order filler is reduced through the constructed first-order dense body, the second-order dense body or the compaction barrel is formed according to different pipe diameters of the extension pipe so that the bearing area between the prefabricated hollow pile and the dense body can be ensured, and the long-term and stable high bearing performance of the prefabricated expanded bore pile is ensured.
本申请公开了一种预制扩底桩施工方法、自动化施工方法及预制扩底桩，其施工方法包括以下步骤：S1.设备进场；S2.下桩身；S3.一阶填料挤密，向延长管中分批次投入一阶填料，以挤料锤挤密成一阶密实体；S4.二阶填料挤密，挤密成包裹延长管的二阶密实体或形成挤密在延长管内的挤密筒以及包裹于延长管底端的终阶密实体；S6.内桩成型。本申请施作的一阶密实体降低了二阶填料下沉概率，针对延长管的不同管径成型二阶密实体或挤密筒以确保预制空心桩与密实体之间的承载面积，确保了预制扩底桩的长久、稳定的高承载性。
