Construction method of microporous cast-in-place pile foundation of mountainous region photovoltaic power station
The invention discloses a construction method of a microporous cast-in-place pile foundation of a mountainous region photovoltaic power station. The construction method comprises the steps of positioning and paying off, pile machine in-place arrangement, drilling machine improvement, drilling machine hole forming, drill lifting and soil unloading, hole depth inspection, concrete cushion layer pouring, embedded part installation, embedded part positioning, concrete pouring, pile foundation finished product detection and acceptance check. Secondary hole cleaning of floating soil around a drilling machine is avoided, the perpendicularity of the pile foundation is ensured, the distance between piles is checked through a rigid ruler, measurement is facilitated, the construction progress is improved, and the cost is saved. Through the embedded part positioning method as well as the two-point one-line principle in pile foundation pouring, the construction speed is increased, and the pile foundation pouring quality is guaranteed. The construction operation process is simple and convenient for constructors to master, and construction guidance can be effectively made. The one-time acceptancepercent of pass is improved, labor is saved, the construction progress is accelerated, and the construction cost is reduced.
本发明公开了一种山地光伏电站微孔灌注桩基础施工工法,其步骤是：定位放线，桩机就位，改进钻机，钻机成孔，提钻卸土，检查孔深，浇筑混凝土垫层，安装预埋件，预埋件定位，浇筑混凝土，桩基成品检测和验收。本发明避免了钻机周围浮土的二次清孔，确保桩基垂直度，桩与桩之间的间距核查通过使用硬性标尺，方便了测量，提高了施工进度，节约了成本。通过预埋件定位方法及桩基浇筑时两点一线原理，加快了施工速度，保证了桩基浇筑质量。施工操作流程简单，便于施工人员掌握，及可有效指导施工。提高了一次验收合格率，节约了人工，加快了施工进度，减少了施工成本。
