Prefabricated pipe pile construction method for photovoltaic support in gravel stratum
The invention discloses a prefabricated pipe pile construction method for a photovoltaic support in a gravel stratum, belongs to the technical field of photovoltaic power stations, and can solve the problem that when a prefabricated pipe pile is arranged in the gravel stratum in an existing construction method, the prefabricated pipe pile is difficult to penetrate or broken in the penetrating process. The method comprises the steps that surveying and setting-out are conducted in a construction area, and the pile positions of all prefabricated pipe piles are determined; water injection is conducted on each pile position, and a wet soil body area is formed; performing rotary excavating in each wet soil body area by using a drilling machine to form a guide hole; the diameter of the guide hole is smaller than that of the wet soil body area and larger than that of the prefabricated pipe pile; soil backfilling is conducted on each guide hole, and a backfilling area is formed; and in each backfill area, a pile driver is used for conducting static pressure piling operation on the prefabricated pipe piles. The construction method is used for construction of the prefabricated pipe pile in the gravel stratum.
本发明公开了一种砂石地层中光伏支架的预制管桩施工方法，属于光伏电站技术领域，能够解决现有施工方法在砂石地层中设置预制管桩时，易出现预制管桩贯入困难或贯入过程碎裂的问题。所述方法包括：在施工区域进行测量放线，确定所有预制管桩的桩位；在每个桩位处进行注水，形成湿润土体区域；在每个湿润土体区域利用钻机旋挖，形成引孔；引孔直径小于湿润土体区域的直径、且大于预制管桩的直径；对每个引孔进行土质回填，形成回填区域；在每个回填区域利用打桩机对预制管桩进行静压打桩操作。本发明用于砂石地层中预制管桩的施工。
