Analysis of New Reinforcing Bar Connection Technology in Single Pile Static Load Tests
This paper has studied the application of steel bar connection technology,replaced the conventional welding connection method in the static load test for vertical uplift of single pile,and achieved the goal of rapid,safe,convenient and cost-saving.Attempted to the preliminary train of thought,a unit was produced for the pull-out test of small-tonnage hollow precast piles.The device utilized the precast pile hollow core steel bar to provide pull-up force characteristics,and implemented an anchor fastening device,allowing the steel bar and the device to connect.The whole assembly process does not require welding,and the disassembled device can be recycled after the end of the test device.The test was conducted on a project in Songjiang,and the results a reference for the colleagues.
