Post-grouting pile foundation visualization test device based on transparent soil
The invention relates to a post-grouting pile foundation visualization test device based on transparent soil, and belongs to the technical field of cast-in-situ bored pile post-grouting engineering. Comprising a model mechanism, a grouting mechanism, a loading mechanism, an image acquisition mechanism, a test pile and transparent soil, the model mechanism is filled with the transparent soil, the test pile is vertically inserted into the middle of the transparent soil, the top end of the test pile is exposed out of the transparent soil and is connected with the loading mechanism, and the loading mechanism is further detachably connected with the top end of the model mechanism. The grouting mechanism and the image acquisition mechanism are both arranged outside the model mechanism, and the grouting mechanism is connected with the top end, exposed out of the transparent soil part, of the test pile. According to the invention, the diffusion condition of grouting slurry, the returning height and thickness of the slurry along the pile body and the form of the final grouting body can be observed in real time; the influence of the grouting parameters on the grouting effect is researched; testing the bearing performance of the test pile; and the weakening effect of pile foundation post-grouting on the mud cake around the pile is researched.
本发明涉及一种基于透明土的后注浆桩基可视化试验装置，属于钻孔灌注桩后注浆工程技术领域。包括：模型机构、注浆机构、加载机构、图像采集机构、试验桩和透明土；所述透明土填充所述模型机构内部，所述试验桩竖直插入所述透明土中间，所述试验桩顶端露出所述透明土，且与所述加载机构连接，所述加载机构还与所述模型机构顶端可拆卸连接，所述注浆机构和所述图像采集机构均设置在所述模型机构外，所述注浆机构与所述试验桩露出所述透明土部分的顶端连接。本发明可以实时观测注浆浆液的扩散情况、浆液沿桩身上返的高度、厚度以及最终注浆体的形态；研究注浆参数对注浆效果的影响；测试试验桩的承载性能；研究桩基后注浆对桩周泥皮的削弱效果。
