Collapsible sand layer lime-soil compaction pile construction process
The invention relates to the technical field of compaction pile construction, in particular to a collapsible sand layer lime-soil compaction pile construction technology which comprises the steps that a pile hole is positioned, and a spiral drilling machine is adopted for executing one-time hole forming, and a drill rod of the spiral drilling machine is pulled out of the hole, a secondary hole forming step is executed through the immersed tube rammer, specifically, an immersed tube of the immersed tube rammer is inserted into the hole, after the bottom end of the immersed tube is located in the hole by a second preset depth, tamping and backfilling are conducted, and the size of the first preset depth is larger than that of the second preset depth. The invention aims to provide a collapsible sand layer lime-soil compaction pile construction process aiming at at least one technical problem related in the background technology.
本申请涉及挤密桩施工技术领域，具体而言，涉及一种湿陷性砂层灰土挤密桩施工工艺，湿陷性砂层灰土挤密桩施工工艺，包括：桩孔定位，采用螺旋钻机执行一次成孔步骤：在湿陷性砂层灰土质区上钻孔至第一预设深度后，将所述螺旋钻机的钻杆从孔中拔出，采用沉管夯锤机执行二次成孔步骤：将沉管夯锤机的沉管插入孔中，所述沉管底端位于所述孔中第二预设深度后，夯实回填，所述第一预设深度的尺寸大于第二预设深度的尺寸。本申请的目的在于针对背景技术中所涉及的至少一个技术问题，提供一种湿陷性砂层灰土挤密桩施工工艺。
