Hollow pile depth control method for prestressed hollow square pile
The invention discloses a hollow pile depth control method for a prestressed hollow square pile, and particularly relates to the technical field of construction engineering.The specific control method comprises the following steps that firstly, preparation is conducted before construction; step 2, constructing a lower-section pile; step 3, connecting upper section piles; 4, pressing the upper section pile; fifthly, the auxiliary piles and the base plates are installed; 6, the depth of the empty pile is controlled; seventhly, pile pulling and cleaning are conducted; and step 8, quality inspection and recording. According to the hollow pile depth control method for the prestressed hollow square pile, the perpendicularity and the butt joint accuracy of the lower-section pile and the upper-section pile are ensured through accurate scale marking of the auxiliary pile and the steel ruler, then accurate control over the hollow pile depth is achieved, sundries are effectively prevented from falling into a pile hole after pile forming through the use of the base plate, and the service life of the pile hole is prolonged. And the whole construction process is clear in steps, easy to operate, capable of reducing the construction difficulty, high in applicability and suitable for various geological conditions and construction environments.
本发明公开了一种预应力空心方桩空桩深度控制方法，具体涉及建设工程技术领域，具体控制方法步骤如下：步骤一、施工前准备；步骤二、下节桩施工；步骤三、上节桩连接；步骤四、上节桩压桩；步骤五、辅助桩与垫板安装；步骤六、控制空桩深度；步骤七、拔桩与清理；步骤八、质量检查与记录。本发明设计的一种预应力空心方桩空桩深度控制方法通过辅助桩和钢尺的精确刻度标注，确保了下节桩和上节桩本身的垂直度和对接准确性，进而实现了空桩深度的精确控制，垫板的使用有效防止了成桩后杂物掉入桩孔，保护了成品质量，整个施工工艺步骤清晰明了，易于操作，降低了施工难度，且适用性强，适用于多种地质条件和施工环境。
