Precast U-shaped concrete sheet pile guide hole pile sinking method and device
The invention relates to the technical field of buildings, in particular to a prefabricated U-shaped concrete sheet pile guide hole pile sinking method and device. The method comprises the following steps: S1, reserving a hoisting hole and a fixing hole in a prefabricated plate pile; the hoisting hole is reserved in the lower one-third position of the pile head of the concrete plate pile; s2, determining the center line of the row pile and calibrating the position of the center point of each sheet pile; s3, drilling machine water injection hole guiding is conducted, a drill rod with the same length as the designed length of the concrete sheet pile is adopted for hole guiding, and the hole guiding range is the length of the concrete sheet pile capable of being driven by a guiding frame at a time; and S4, a first concrete sheet pile is hit, and the perpendicularity of the concrete sheet pile during pile sinking is manually controlled through hanging in the pile driving process. According to the prefabricated U-shaped concrete sheet pile guide hole pile sinking method and device, by adding the drilling machine guide hole construction procedure, resistance in the concrete sheet pile sinking process is reduced, the perpendicularity and the attaching degree of the concrete sheet pile can be better controlled in the construction process, and the construction quality is improved.
本发明涉及建筑技术领域，尤其涉及一种预制U型混凝土板桩引孔沉桩方法及其装置。步骤如下：S1.预制板桩留置吊装孔及固定孔；吊装孔留置在混凝土板桩桩头向下三分之一处；S2.确定排桩中心线并标定每根板桩的中心点位置；S3.钻机注水引孔，采用与混凝土板桩设计长度一样的钻杆引孔，引孔范围为导向架一次性可施打混凝土板桩长度；S4.施打第一根混凝土板桩，打桩过程通过吊垂，人工控制沉桩时混凝土板桩的垂直度。本发明提供的一种预制U型混凝土板桩引孔沉桩方法及其装置，通过增加钻机引孔的施工工序，减少混凝土板桩沉桩过程中的阻力，在施工中能更好地控制混凝土板桩的垂直度与贴合程度，提高了施工质量。
