Simulation demonstration method for immersed tube cast-in-place pile foot lifting accident field processing
The application provides a simulation demonstration method for immersed tube cast-in-place pile foot lifting accident field processing, and belongs to the technical field of tests of foundations or foundation structures of water conservancy projects and the like. After a set amount of cotton fiber is added into a sleeve, a nitric acid solution is dropwise added, then a protein solution is dropwiseadded, a soft soil layer is simulated, and a foot hanging pile is formed; the pile body is placed in the sleeve until the bottom of the pile body makes contact with cotton fiber, pressure is applied,and the pile body descends to the set height; the pressure is removed, the pile body is taken out, and simulation mortar is added into the sleeve until the simulation mortar submerges the liquid in the sleeve; and the pile body is placed again until the bottom of the pile body makes contact with the simulated mortar, pressure is applied, the pile body descends to the set height, the time when thepile body descends to the set height twice is compared, and the bearing capacity rising state is determined. The method is applied to simulating the state of the immersed tube cast-in-place pile, theimmersed tube cast-in-place effect can be visually displayed, and predictability of the state of the immersed tube cast-in-place pile is achieved.
本申请提供一种沉管灌注桩吊脚事故现场处理的模拟演示方法，属于水利工程等基础或基础结构的试验技术领域。向套管中加入设定量的棉絮后，滴加硝酸溶液，再滴加蛋白质溶液，模拟松软土层，形成吊脚桩；将桩身置于套管内至其底部与棉絮接触，施压，桩身下降至设定高度；撤压，取出桩身，向套管内加入模拟砂浆至没过套管中的液体；再次置入桩身至其底部与模拟砂浆接触，施压，桩身下降至设定高度，比较两次下降至设定高度的时间，确定承载力回升状态。将本申请应用于模拟沉管灌注桩状态，可直观显示沉管灌注效果，实现沉管灌注桩状态的可预测性。
