Large-diameter prefabricated pipe pile construction method under complex geology
The invention discloses a large-diameter prefabricated pipe pile construction method under complex geology, which comprises the following steps of: S1, performing trial pile sinking, and performing a simulation test on parameter data of the trial pile sinking to obtain a planned construction scheme; s2, the piling position of the prefabricated pipe pile is determined; s3, hole guiding is carried out; s4, the pile is taken out, and the first prefabricated pipe pile welded with the pile tip is vertically sunk into the hole; s5, a second prefabricated pipe pile is taken, and coaxial pile extension is conducted on the second prefabricated pipe pile and the first prefabricated pipe pile; after pile splicing, the pile driver is used for vertically hammering again; the pile sinking process of all the prefabricated pipe piles is completed in sequence; and S6, a static load experiment is conducted within the preset time after pile sinking of all the prefabricated pipe piles is completed, static load experiment data are obtained, and the bearing capacity conditions of the prefabricated pipe piles under all the working conditions of the pile-beam integrated bridge girder erection machine are simulated. The large-diameter prefabricated pipe pile construction method under the complex geology can provide a reference basis for follow-up prefabricated bridge large-diameter pipe pile foundation construction.
本发明公开了一种复杂地质下大直径预制管桩施工方法，包括以下步骤：S1、试沉桩，并对试沉桩的参数数据进行模拟试验，得到计划施工方案；S2、确定预制管桩的打桩位置；S3、进行引孔；S4、取桩并使焊接有桩尖的第一根预制管桩垂直沉入孔内；S5、取桩第二根预制管桩，并使第二根预制管桩与第一根预制管桩进行同轴接桩；接桩后再次使用打桩机竖直锤击；依次完成所有预制管桩的沉桩过程；S6、在所有预制管桩沉桩完成后的预设时间内进行静载实验，获取静载实验数据，并模拟桩梁一体化架桥机各工况下预制管桩的承载力情况。本发明的复杂地质下大直径预制管桩施工方法可以为后续预制拼装桥梁大直径管桩基础施工提供参考依据。
