Indoor soil-squeezing pile soil-squeezing effect simulation experiment system
The invention discloses an indoor soil squeezing pile soil squeezing effect simulation experiment system. The device comprises a model box, a model soil squeezing pile, a moisture content change system, a load control system, an air pressure control system and a data acquisition device, the model box is of a cuboid structure, a test box body is composed of a steel structure frame and a tempered glass plate, various parameters of soil are determined according to test requirements, and soil sample preparation is completed; filling is carried out in a test box body by adopting a layered compaction method, a model soil-squeezing pile is composed of a semi-cylinder with a sealed top and a pile tip, two holes are reserved in the model soil-squeezing pile, and simulation of water content change, load change and pile diameter change in a natural state is realized by utilizing a water content change system, a load control system and an air pressure control system. And data monitored by each sensor is collected through the data acquisition system. The device can be used for testing the soil-squeezing effect of the soil-squeezing pile under different conditions, and overcomes the defect that the soil-squeezing effect of the soil-squeezing pile can only be researched through theoretical analysis in the prior art.
本发明公开了一种室内挤土桩挤土效应模拟实验系统。该装置包括模型箱、模型挤土桩、含水率变化系统、荷载控制系统，气压控制系统、数据采集装置，模型箱为长方体结构，试验箱体由钢结构框架和钢化玻璃板构成，根据试验需求确定土的各项参数并完成土样配制，采用分层击实的方法在试验箱体中进行填土，模型挤土桩由顶部密封的半圆柱体和桩尖组成，并预留有两个孔洞，利用含水率变化系统、荷载控制系统，气压控制系统实现对自然状态下含水率变化、荷载变化以及桩径变化的模拟，通过数据采集系统收集各个传感器监测到的数据。本发明可进行不同情况下的挤土桩挤土效应试验，克服了以往只能通过理论分析来研究挤土桩挤土效应的不足。
