Load box for testing bearing capacity of pile foundation and testing method thereof
The invention relates to a load box for testing the bearing capacity of a pile foundation and a testing method thereof. A plurality of pile side load boxes are fixed on the outer circumference of a reinforcement cage from the top end to the bottom end, and the pile side load boxes located on the same plane are symmetrically arranged relative to the reinforcement cage; the pile side load box comprises an upper-section box body, a middle-section box body, a lower-section box body and a bearing plate. Fixing a pile end load box at the bottom end of the reinforcement cage; the pile end load box comprises a spring, a pile end jack, a pile end bearing plate, a displacement sensor and a pressure sensor. The pile side friction force and the pile end resistance can be directly measured, and the testing cost is greatly saved.
本发明涉及一种用于桩基承载力测试荷载箱及其测试方法，在钢筋笼外部圆周上由顶端至底端固定若干桩侧荷载箱，位于同一平面的桩侧荷载箱相对钢筋笼对称设置；桩侧荷载箱包括上段箱体、中段箱体、下段箱体以及承压板。在钢筋笼的底端固定桩端荷载箱；桩端荷载箱包括弹簧、桩端千斤顶、桩端承压板、位移传感器以及压力传感器。本发明能够直接测出桩侧摩擦力以及桩端阻力，大大节约了测试成本。
