Fabricated foundation pile anti-pulling static load test device and method
The invention provides a fabricated foundation pile anti-pulling static load test device and method. A foundation pile is provided with anti-pulling steel bars stretching out of the end face, and the foundation pile anti-pulling static load test device comprises a counter-force device and a loading device. The counter-force device comprises a supporting platform and a first buttress, and the loading device comprises an anchoring plate, a jack and an anti-pulling steel bar locking structure. The anti-pulling steel bar locking structure comprises fixing pieces, first anchoring beams, second anchoring beams and connecting pieces, the second anchoring beams are erected on the first anchoring beams, a gap allowing the anti-pulling steel bars to stretch out is formed between every two adjacent second anchoring beams, the fixing pieces are used for being fixedly connected with the anti-pulling steel bars, the fixing pieces abut against the two adjacent second anchoring beams, and the connecting pieces are used for connecting the anchoring plate and the first anchoring beams. The fabricated foundation pile anti-pulling static load test device is suitable for anti-pulling piles of various types and diameters, the test load range is large, welding is not needed, assembly is flexible, installation is convenient and fast, the test preparation work time is shortened, and the anti-pulling test success rate is increased.
本发明提供了一种装配式基桩抗拔静载试验装置及方法，基桩具有伸出于端面的抗拔钢筋，基桩抗拔静载试验装置包括反力装置和加载装置，反力装置包括支撑平台和第一支墩，加载装置包括锚定板、千斤顶和抗拔钢筋锁定结构，抗拔钢筋锁定结构包括固定件、第一锚定梁、第二锚定梁和连接件，第二锚定梁搭设于第一锚定梁上，相邻两个第二锚定梁之间具有供抗拔钢筋伸出的间距，固定件用于与抗拔钢筋固定连接，固定件与相邻的两个第二锚定梁抵紧，连接件用于连接锚定板和第一锚定梁。该基桩抗拔静载试验装置适应于各种类型和直径的抗拔桩且试验荷载范围大，不需要焊接，组装灵活、安装便捷，缩短了试验准备工作时间，提高了抗拔试验成功率。
