Pile testing structure, pile testing method and construction method for cast-in-situ bored pile of shoal foundation
The invention discloses a shoal foundation cast-in-situ bored pile test pile structure, method and construction method.The pile test method comprises the steps that S100, it is checked and determined that a pile head protection cylinder is stably installed, and it is ensured that all connecting pieces are correctly in place; s200, equipment for providing stable loading is arranged above the test pile, a distributive girder or a steel plate is used for dispersing the load, and it is ensured that the load can be evenly transmitted to the test pile; s300, loads are gradually applied in a graded mode according to the preset loading rate, and after each stage of load is applied, a certain time is waited to observe the settlement condition of the pile; s400, the settlement amount of the pile top is monitored, and test data including the settlement amount of the pile top under each stage of load are recorded; s500, analyzing the relation curve of pile top settlement and load in the loading process, determining the ultimate bearing capacity of the test pile, and continuing loading until the preset maximum test load is reached; and S600, when the test meets the termination standard, final data are unloaded and recorded, and after loading equipment is dismantled, the pile head pile casing is dismantled. One-time forming of the pile head is achieved, and construction cost is reduced.
本发明公开了一种海涂地基钻孔灌注桩试桩结构、试桩方法及施工方法，试桩方法包括：S100、检查确定桩头护筒安装稳固，确保所有的连接件均已正确就位；S200、在试桩上方设置提供稳定加载的设备，使用分配梁或钢板来分散荷载，确保能够均匀传递荷载给试桩；S300、按照预定的加载速率逐渐分级施加荷载，每一级荷载施加后等待一定时间以观测桩的沉降情况；S400、监测桩顶沉降量，记录包括每一级荷载下桩顶的沉降量在内的试验数据；S500、分析加载过程中桩顶沉降与荷载的关系曲线，确定试桩的极限承载力，继续加载直至达到了预定的最大测试荷载；S600、当试验满足终止标准时，卸载并记录最终数据拆除加载设备后拆除桩头护筒。实现桩头一次成型、降低施工成本。
