Collapsible loess foundation on-site water immersion test device and method from bottom to top
The invention discloses a collapsible loess foundation bottom-to-top on-site water immersion test device and method.The device comprises a water immersion exploratory well and an on-site water immersion test structure, the on-site water immersion test structure comprises a water immersion pipeline mechanism and a radiation pipeline mechanism, and the radiation pipeline mechanism comprises multiple sets of radiation pipeline components; each radiation pipeline unit comprises a plurality of radiation pipes which are obliquely arranged downwards, and a plurality of water soaking holes which are formed in the length direction of the radiation pipes are formed in the bottoms of the radiation pipes; the soaking pipeline mechanism comprises a plurality of groups of soaking pipes arranged along the inner side wall of the soaking exploratory well; the method comprises the following steps: 1, excavating a soaking test pit and forming a soaking exploratory well; 2, installing a radiation pipeline mechanism; 3, mounting a soaking pipeline mechanism; 4, backfilling the immersed exploratory well and installing a water level monitoring pipe; 5, mounting a monitoring structure; and 6, carrying out on-site water immersion test on the collapsible loess foundation from bottom to top. The underground water level lifting working condition is simulated through water immersion from bottom to top, and the collapsibility type and the collapsibility coefficient can be judged conveniently.
本发明公开了一种湿陷性黄土地基自下而上现场浸水试验装置及方法，该装置包括浸水探井和现场浸水试验结构，现场浸水试验结构包括浸水管道机构和辐射管道机构，辐射管道机构包括多组辐射管道部件，每组辐射管道单元包括多个倾斜向下布设的辐射管，辐射管底部开设有多个沿辐射管长度方向布设的浸水孔；浸水管道机构包括多组沿浸水探井内侧壁布设的浸水管；该方法包括以下步骤：一、浸水试坑开挖及浸水探井形成；二、安装辐射管道机构；三、安装浸水管道机构；四、浸水探井回填及水位监测管安装；五、监测结构的安装；六、湿陷性黄土地基自下而上现场浸水试验。本发明自下而上浸水模拟地下水位抬升工况，便于湿陷类型和湿陷性系数判断。
