Photovoltaic support foundation suitable for sandy soil geology and construction method thereof
The invention relates to a photovoltaic support foundation suitable for sandy soil geology and a construction method thereof. The construction method comprises the following steps: designing a support foundation, wherein the support foundation adopts a micro pore-forming cast-in-place pile form; the pipe piles are finished steel pipe piles; protective caps which are 200mm higher than the ground and have the diameter of 250mm are designed at the positions, exposed out of the ground, of the pipe piles, so that the stability of the support foundation is enhanced; c30 fine aggregate concrete is poured into the inner core of the pipe pile, the pouring depth is 1000 mm higher than the ground, and the C30 fine aggregate concrete is poured to the drainage hole in the pipe pile; drainage holes are formed in the finished pipe pile and used for completely draining accumulated water in the steel pipe, and it is guaranteed that the pipe pile steel pipe is not affected by corrosion of rainwater and the like. According to the technology, the drilling diameter and depth of the support foundation can be effectively reduced, meanwhile, the stability of the foundation structure is not affected, the difficulty of large-diameter drilling and large-depth drilling is reduced, and the construction efficiency is improved. The construction process of the micro pore-forming cast-in-place pile is optimized, and after drilling is completed, the PVC sleeve wall protection technology is adopted to solve the problem that a quicksand layer below-1.5 m collapses and cannot form a pore.
本发明是一种适用于沙土地质的光伏支架基础及其建造方法，包括设计支架基础：支架基础采用微型成孔灌注桩形式；管桩采用成品钢管桩；在管桩露出地面设计高出地面200mm的直径为ϕ250mm的保护帽，增强支架基础的稳定性；在管桩内芯中浇筑C30细石混凝土，浇筑深度为高出地面1000mm，且浇筑至管桩上的排水孔处；在成品管桩上面设排水孔，用以将钢管内部的积水排除干净，确保管桩钢管不受雨水等的腐蚀影响。本发明技术，可以有效减小支架基础钻孔直径及深度，同时基础结构稳定性不受影响，降低了大直径钻孔、大深度钻孔的难度，提高了施工效率。对于微型成孔灌注桩的施工方面进行工序的优化，在钻孔完成后采用PVC套管护壁技术解决‑1.5m以下流沙层坍塌无法成孔的难题。
