Steel pipe column post-insertion construction method based on reverse construction
The invention relates to a steel pipe column post-insertion construction method based on reverse construction, and relates to a one-column one-pile post-insertion construction method based on reverse construction, which comprises the following steps: S1, before a steel pipe column is implanted, carrying out ground hardening treatment, positioning and drilling, and pouring super-retarding concrete with optimized proportion as cast-in-place pile concrete, a steel column fixing platform and a DAG steel pipe column implanting machine are in place; s2, a DAG steel pipe column implanting machine is installed; s3, the steel pipe column is installed, a DAG steel pipe column implanting machine is used for downwards inserting the steel pipe column to the designed elevation, and during the period, a double-measurement and double-control method and an automatic leveling laser plumb bob instrument method are adopted for detecting and calibrating the perpendicularity; and 4, after the steel pipe column is implanted, a sealing mechanism at the top end of the steel pipe column is installed, and after pile foundation concrete is initially set, backfilling and pouring are conducted by adopting a steel pipe column inner concrete rear pouring method.
本发明为一种基于逆作施工的钢管柱后插施工方法，涉及一种逆作施工一柱一桩后插法施工方法，包括，步骤S1：植入钢管柱前，进行地面硬化处理，定位钻孔，灌注配比经过优化的超缓凝混凝土作为灌注桩混凝土，钢柱固定平台以及DAG钢管柱植入机就位；步骤S2：安装DAG钢管柱植入机；步骤S3：安装钢管柱，使用DAG钢管柱植入机下插钢管柱至设计标高，期间采用双测双控方法以及自动安平激光铅锤仪方法检测校准垂直度；步骤4：完成钢管柱的植入后，安装钢管柱顶端密封机构，待桩基混凝土初凝，采用钢管柱内混凝土后置浇筑方法，进行回填、浇筑。
