Rectangular haunched precast concrete pile construction process
The invention discloses a rectangular haunched precast concrete pile construction process, and belongs to the technical field of concrete pile construction. The rectangular haunched precast concrete pile construction process comprises the following steps of S1, splicing a rectangular haunched precast concrete pile, S2, carrying out lofting and positioning according to provided coordinate reference points, S3, excavating a groove according to a lofted enclosure center line, and laying guide positioning profile steel on the two sides of the excavated working groove, S4, moving a pile machine in position according to a determined position, and S5, starting a mortar pump when a drill rod of the three-shaft mixing pile machine sinks to a designed pile top elevation of the rectangular haunched precast concrete pile, sinking the drill rod after pure cement slurry reaches a mixing head, and grouting, mixing and sinking simultaneously. The rectangular haunched precast concrete pile construction process has the efforts of being short in construction period, economical, reliable in quality, environmentally friendly and easy to construct.
本发明公开了一种矩形加腋预制混凝土桩施工工艺，属于混凝土桩施工技术领域，包括以下步骤：S1、对矩形加腋预制混凝土桩进行拼接，S2、根据提供的坐标基准点，进行放样定位，S3、根据放样出的围护中心线开挖沟槽，并在开挖的工作沟槽两侧铺设导向定位型钢，S4、根据确定的位置移动桩机就位，S5、在三轴搅拌桩机钻杆下沉到矩形加腋预制混凝土桩的设计桩顶标高时，开动灰浆泵，待纯水泥浆到达搅拌头后，下沉钻杆，边注浆、边搅拌及边下沉。本发明，具有施工周期短、经济节约、质量可靠、绿色环保及施工简单的效果。
