The invention discloses a photovoltaic cast-in-place pile construction method in a desert area, and relates to the technical field of photovoltaic cast-in-place piles. The construction method comprises the following steps of site leveling, water ramming treatment of aeolian sand, pile foundation construction platform treatment, pile casing burying, slurry preparation, slurry stirring machine slurry preparation, drilling, hole cleaning, reinforcement cage adjustment and protection, concrete pouring and the like. The hole forming speed is high, the drilling speed is high by adopting the rotary excavating drill, the pile foundation construction time can be shortened, the construction progress is accelerated, and the hole collapse risk is greatly reduced; before drilling, the pile position foundation is filled with water and tamped until a sand layer around the upper portion is tight and wetted thoroughly, and the stability of the hole wall is improved. 本发明公开了一种沙漠地区光伏灌注桩施工方法，涉及光伏灌注桩的技术领域。施工方法包括如下步骤：场地平整、水夯处理风积沙、桩
