Pile-loading method test pile site balancing method
The invention discloses a pile-loading method test pile site balancing method, and belongs to the technical field of pile foundation construction. The pile-loading method test pile site balancing method comprises the steps that the arrangement condition of a bottom supporting pipe pile of a pile-loading method test pile is determined; the pipe pile is driven into a soil body; a jack is installed at the top of the pipe pile; a jacking support is placed on the upper portion of the jack; a right-angle seat is installed on the upper portion of the jacking support; steel plates are sequentially hoisted on the right-angle seat; the height difference of the surfaces of the hoisted steel plates is measured through a level bubble of a level ruler so as to judge whether the steel plates are in a horizontal state or not, and the steel plates are adjusted to be horizontal through the jack at the top of the pipe pile; a steel beam and a concrete balancing weight are hoisted; and the height difference of the surfaces of the hoisted steel plates is measured through the level ruler again so as to judge whether the steel plates are in the horizontal state or not, and the steel plates are adjusted to be horizontal through the jack at the top of the pipe pile. The pile-loading method test pile site balancing method is suitable for the situation that site conditions such as large soil property differences are poor during pile-loading method test pile, the pipe pile is driven into the soil body to serve as a support, the jack installed at the top of the pipe pile is adjusted so as to keep the upper structure horizontal, and therefore the test result reliability of the pile-loading method test pile is guaranteed.
本发明公开了一种堆载法试桩场地平衡方法,属于桩基施工技术领域;包括确定堆载法试桩底部支撑管桩布置情况;将管桩打入土体;在管桩顶部安装千斤顶;在千斤顶上部放置顶托;在顶托上部安装直角座;在直角座上按顺序吊装钢板;通过水平尺的水准泡测量吊装钢板表面的高差以判断钢板是否处于水平状态,通过管桩顶部的千斤顶调整钢板水平;吊装钢梁、混凝土配重块;再次通过水平尺测量吊装钢板表面的高差以判断钢板是否处于水平状态,通过管桩顶部的千斤顶调整钢板水平。本发明适用于堆载法试桩时土质差异大等场地条件不佳的情况,通过打入管桩作为支撑,调整安装在管桩顶部的千斤顶以保持上部结构水平,从而保证堆载法试桩的试验结果可信度。
