Large-tonnage single pile anti-pulling static load test device and test method
The invention discloses a large-tonnage single-pile anti-pulling static load test device which comprises a main beam, load loading devices are arranged on the two sides of the main beam, a pre-embedded type positioning traction structure is arranged in the middle of the main beam, the lower end of the pre-embedded type positioning traction structure is connected with a pile foundation structure, and the lower end of the pre-embedded type positioning traction structure is connected with the pile foundation structure. The upper end of the load loading device is connected with the fastening structure, and the load loading device drives the embedded positioning traction structure to ascend by driving the main beam to ascend. A large-tonnage single-pile anti-pulling static load test method comprises the steps that firstly, the using number, the anchoring length and the pre-buried depth of pre-buried type positioning traction structures are calculated; secondly, the embedded positioning traction structure is embedded into the pile foundation structure; and thirdly, a load is applied for testing. On one hand, the problem that load centering is not easy to control during installation is solved; on the other hand, the loading device has the advantages of being simple in structure, high in practicability, capable of providing large-tonnage uplift loads, wide in application range and the like.
本发明公开了一种大吨位单桩抗拔静载试验装置，包括一种大吨位单桩抗拔静载试验装置，包括主梁，所述主梁的两侧设有载荷加载装置，中部设有预埋式定位牵引结构，所述预埋式定位牵引结构的下端和桩基结构连接，上端和紧固结构连接，所述载荷加载装置通过驱动主梁上升而带动预埋式定位牵引结构上升。一种大吨位单桩抗拔静载试验方法，包括步骤一、计算预埋式定位牵引结构的使用数量、锚固长度、预埋深度；步骤二、将预埋式定位牵引结构预埋至桩基结构中，步骤三、施加载荷进行测试。本发明一方面解决了安装中荷载对中不易控制的问题；另一方面本发明所述的加载装置具有构造简单，实用性强、可提供大吨位上拔荷载、应用范围广等优点。
