Steel stand column post-insertion construction method
The invention belongs to the technical field of building construction, and particularly relates to a steel stand column post-insertion construction method. The steel stand column post-insertion construction method comprises the following steps of performing ground hardening treatment, placing a pile position center point, embedding a steel casing, and drilling to form a hole; detecting the perpendicularity of a pile hole; mounting a pile reinforcement cage, pouring super-delayed coagulation concrete to the pile top elevation by a lower guide pipe and performing over-pouring, placing a steel column fixing platform in place, placing a steel column implanting machine in place, hoisting a steel pipe column into the steel column implanting machine, centering and adjusting the perpendicularity; and clamping and fixing the steel pipe column, pressing the steel pipe column to a column top elevation, then calibrating the perpendicularity of the steel pipe column, clamping and fixing the steel pipe column, and after pile foundation concrete is initially set, uniformly and symmetrically backfilling the periphery of the steel pipe column to column body gravels. According to the method, the installation precision and reliability of the steel pipe column are improved, the perpendicularity of the steel pipe column is pre-controlled in advance, the one-column-one-pile construction quality is reliably guaranteed, meanwhile, the construction efficiency is improved, the construction period is shortened, and the construction safety risk and cost are reduced.
本发明属于建筑施工技术领域，尤其是钢立柱后插法施工工法，包括以下步骤：地面硬化处理，放桩位中心点，埋设钢护筒，钻进成孔；桩孔垂直度检测；安装桩钢筋笼,下导管灌注超缓凝混凝土至桩顶标高并超灌,钢柱固定平台就位,钢立柱植入机就位,吊放钢管柱至钢立柱植入机内,对中心和调整垂直度；夹紧钢管柱固定，钢管柱压入至柱顶标高，然后校准钢管柱垂直度，夹紧钢管柱固定，桩基混凝土初凝后，钢管柱四周均匀对称回填至柱身碎石；本发明了提高钢管柱安装精度和可靠性，实现了钢管柱垂直度的提前预控，使一柱一桩施工质量得到了可靠的保证，同时，还提高了施工效率，加快了施工工期，降低了施工安全风险和成本。
