Complex interactive silt stratum rotary excavating hole-forming cast-in-place pile and construction method thereof
The invention relates to a rotary drilling cast-in-place pile for a complex interactive silt stratum and a construction method of the rotary drilling cast-in-place pile. The construction method comprises the steps that firstly, a steel casing is buried; secondly, a steel casing integrated orifice centering device is installed; step 3, forming a hole; step 4, hole cleaning; 5, measuring the sediment thickness; and sixthly, a reinforcement cage is lowered. By means of a series of improvement technologies, the purposes of reducing the sand content of slurry, efficiently positioning the steel casing, efficiently fixing and sinking the reinforcement cage, preventing hole shrinkage and hole collapse, measuring the sediment thickness, increasing the height of the hole opening casing and the like are achieved, the hole forming quality and precision are improved, and good technical and economic benefits can be obtained when the method is applied to actual engineering.
本发明涉及复杂交互粉砂地层旋挖成孔灌注桩及其施工方法，包括：步骤一、埋设钢护筒；步骤二、安装钢护筒一体化孔口对中装置；步骤三、成孔；步骤四、清孔；步骤五、测量沉渣厚度；步骤六、下放钢筋笼。本申请通过系列改进技术实现降低泥浆含沙率、高效定位钢护筒、高效固定和沉放钢筋笼、预防缩径塌孔、沉渣厚度测量、孔口护筒加高等，提高成孔质量和精度，应用于实际工程中可取得较好的技术经济效益。
