Support pile construction technology
The invention provides a support pile construction process, which relates to the field of constructional engineering and comprises the following steps: S1, lofting and positioning; s2, the rotary drilling machine is in place, the rotary drilling machine is moved to a designated pile position, and the perpendicularity and the levelness of the rotary drilling machine are adjusted; s3, a pile casing is embedded, and the diameter of the pile casing is larger than that of the pile hole; s4, drilling and hole forming are conducted, after the pile casing is buried and positioned, measurement and positioning are conducted again, proper drilling parameters are selected, and then rotary drilling is conducted on the pile hole; s5, hole cleaning; s6, a reinforcement cage is manufactured and placed; S7, a guide pipe is put down, the guide pipe is firmly fixed at the hole opening connecting position, and a sealing ring is arranged; s8, concrete pouring is conducted, specifically, high-performance concrete is adopted and poured into the hopper through the hole opening; s9, the pile casing is pulled out; s10, the pile hole is backfilled, after pile hole concrete pouring is completed, the portion, not filled with concrete, of the upper portion is backfilled, and after backfilling is full, the hole opening is sealed again with concrete; through the steps, the construction efficiency is improved, the quality of the support pile is improved, and pollution to the environment in the construction process is reduced.
本发明提供的一种支护桩施工工艺，涉及建筑工程领域，包括以下步骤：S1放样定位；S2旋挖机就位，将旋挖机移动到指定桩位，并调整旋挖机的垂直度和水平度；S3埋设护筒，护筒直径大于桩孔直径；S4钻进成孔，在所述埋设护筒并定位后，重新测量、定位，选择合适的钻进参数，而后旋挖桩孔；S5清孔；S6钢筋笼制作与安放：S7下导管，导管在孔口连接处固定牢固，并设置密封圈；S8混凝土浇筑，采用高性能混凝土，并通过孔口倒入料斗内；S9起拔护筒；S10回填桩孔，桩孔混凝土浇筑完成后，将上部未灌混凝土部分进行回填，回填满后，用混凝土重新将孔口封住；本发明通过上述步骤，提高了施工效率、提高了支护桩的质量和减少施工过程中对环境的污染。
