Rotary drilling rig square pile construction method
The invention belongs to the technical field of engineering construction, and particularly relates to a rotary drilling rig square pile construction method. The rotary drilling rig square pile construction method comprises the following specific steps that S1, a site is leveled, specifically, the land at the construction position is leveled and compacted in advance; S2, surveying and setting-out are conducted, specifically, data are measured on the leveled site, the site is set out, and the drilling position needing to be constructed is marked; S3, a well mouth concrete retaining wall is constructed, specifically, the retaining wall is poured through concrete at the drilling position needing to be constructed; S4, a drilling rig is in place, specifically, the drilling rig is moved to the retaining wall, before the drilling rig is in place, the ground is compacted, the stability of the drilling rig is ensured, and inclination or displacement caused by sinking in the drilling process is avoided; and S5, the verticality of the drilling rig is adjusted, specifically, the verticality of a pile foundation after hole forming is ensured. According to the rotary drilling rig square pile construction method, manual hole digging is replaced with rotary drilling rig square pile construction, so that the downhole operation of labor personnel is reduced, the project safety production risk is reduced, and the occurrence of personal accidental injury is prevented from the source; and contribution is made for speed increasing and efficiency increasing of national infrastructure construction.
本发明属于工程施工技术领域，具体为一种旋挖钻机方桩工法，该旋挖钻机方桩工法的具体步骤如下：S1：场地平整：预先对施工位置土地平整并压实；S2：测量放线：在平整的场地上测量数据并对场地放线，标出需要施工钻挖位置；S3：井口砼护壁：在需要施工钻挖位置通过混凝土浇筑护壁；S4：钻机就位：钻机移动至护壁处，钻机就位前，压实地面，确保钻机的平稳，在钻进过程中不会因沉陷产生倾斜或位移；S5：钻机调垂：为确保桩基成孔后的垂直度。旋挖钻机方桩施工替换人工挖孔有利于减少劳务人员井下作业，降低项目安全生产风险，从源头上阻止人身意外伤害的发生。为国家基础设施建设提速增效贡献力量。
