Loess plateau landform pile foundation construction method
The invention discloses a loess plateau landform pile foundation construction method. A precast concrete bottom plate is arranged, an electric Luoyang shovel is adopted to prevent a steel wire rope from shaking a shaped triangular hanging bracket, an electric Luoyang shovel soil falling prevention in-situ soil unloading and transporting device is adopted, a wall collision and soil falling prevention reinforcement cage is used for hanging a shaped positioning frame, and a water falling prevention sealing cover is arranged in the hole forming process and after hole forming. The method mainly comprises the construction steps of (1) construction preparation, (2) precast concrete bottom plate hoisting, (3) steel casing embedding, (4) Luoyang shovel in-place, (5) tunneling, (6) heavy hammer tamping, (7) reinforcement cage hanging and shaped positioning frame installation, and (8) reinforcement cage installation, guide pipe installation and concrete pouring. According to the loess plateau landform pile foundation and the construction method, Luoyang shovel pile foundation construction is comprehensively considered and selected according to the characteristics of loess plateau landform, water shortage and high environmental protection requirement and the local geological characteristics, and obvious social benefits and economic benefits are achieved.
本发明公开了一种黄土台塬地貌桩基施工方法，设置预制混凝土底板，采用电动洛阳铲防止钢丝绳晃动定型化三角形吊架，电动洛阳铲防落土原位卸运土装置，防碰壁落土钢筋笼吊放定型化定位架，成孔过程中及成孔后设置防落水封盖。其主要施工步骤包括：（1）施工准备，（2）预制混凝土底板吊装，（3）钢护筒埋设，（4）洛阳铲就位，（5）掘进，（6）重锤夯实，（7）钢筋笼吊放定型化定位架安装，（8）钢筋笼安设、导管安装、灌注砼。本发明涉及的黄土台塬地貌桩基及施工方法，针对黄土台塬地貌、缺水和环保要求高度的特点，结合地方地质特点综合考虑选择了洛阳铲桩基施工，具有明显的社会效益和经济效益。
