Anchor pile cross beam counter-force device suitable for high-altitude static load test and test method of anchor pile cross beam counter-force device
The invention discloses an anchor pile cross beam counter-force device suitable for a high-altitude static load test and a test method thereof. The anchor pile cross beam counter-force device comprises an anchor pile, a main beam, a secondary beam and a jack, the anchor piles are arranged on two sides of the test pile; a lower mounting plate is arranged close to the lower end in the anchor pile; an upper mounting plate is arranged at the top of the anchor pile; a sleeve is arranged between the upper mounting plate and the lower mounting plate; prestressed tendons are arranged in the sleeves in a penetrating manner; steel cylinders are mounted at the tops of the anchor piles; a connecting beam longitudinally penetrates through the steel cylinder; the secondary beams are mounted at the tops of the steel cylinders on two sides of the test pile; the secondary beam and the connecting beam are tied through a first tying piece; the jack is mounted at the top of the test pile; the girder is arranged at the top of the jack; the main beam and the secondary beams on the two sides are tied through second tying pieces. An adjustable lantern ring is mounted at the lower part of the test pile; displacement meters are arranged on the two sides of the adjustable lantern ring respectively. The pile foundation static load test device solves the technical problems that a traditional pile foundation static load test device is long in test preparation time, high in cost, high in test site requirement, large in occupied area and prone to causing inaccurate test results, and potential safety hazards exist.
一种适用于高空静载试验的锚桩横梁反力装置及其试验方法，包括锚桩、主梁、次梁和千斤顶；锚桩布置在试桩两侧；锚桩中、靠近下端设有下安装板；锚桩顶部设有上安装板；上安装板与下安装板之间设有套管；套管内穿设有预应力筋；锚桩顶部安装有钢筒；钢筒中纵向贯穿有连接梁；次梁安装在试桩两侧的钢筒顶部；次梁与连接梁之间通过第一拉结件拉结；千斤顶安装在试桩顶部；主梁设在千斤顶顶部；主梁与两侧的次梁通过第二拉结件拉结；试桩下部安装有可调节套环；可调节套环两侧分别设有位移计。本发明解决了传统的桩基静载试验装置试验准备时间长、成本高，存在安全隐患以及对试验场地要求较高、占用面积较大以及易造成实验结果不准确的技术问题。
