A survey device for foundation collapsibility assessment

Abstract

The invention discloses a survey device used for the assessment of the collapsibility of foundations, and relates to the technical field of foundation assessment. The present invention includes a power device, a lowering device, a pressing device, a fixing device and a bottom device, the lowering device and the fixing device are both arranged on the top of the bottom device, the lowering device and the fixing device are fixedly connected with the bottom device, and one side of the fixing device extends into the lowering device and slidingly connected with the lowering device, the power device is arranged on the top of the lowering device, the power device is fixedly connected with the lowering device, the pressing device is arranged on the side of the lowering device, and the pressing device is in contact with the lowering device. The invention can adjust the descending height of the evaluating device by setting the descending device and the pressing device, so that the descending height of the evaluating device can be adjusted according to actual needs, thereby expanding the use range of the entire device and improving the practicability of the device.

Description

technical field [0001] The invention belongs to the technical field of foundation assessment, and in particular relates to a survey device used for foundation collapsibility assessment. Background technique [0002] After being soaked by water under a certain pressure, the structure of loess is rapidly destroyed, resulting in significant additional subsidence, which is called collapsibility. It is a unique engineering geological property of loess. The most fundamental reason for loess collapsibility is that it has obvious water-contacting weakened structures and special components and structures that are conducive to collapsibility. The former refers to the phenomenon that the loess is less subsidence under its own weight after it encounters water; the latter refers to the additional subsidence caused by the additional load after the loess is soaked in water. When evaluating the collapsibility of the foundation The evaluation instrument needs to be used. However, the exist...

Problems solved by technology

[0003] The object of the present invention is to provide a kind of investigation device that is used for foundation collapsibility assessment, to solve the existing problem: the existing survey device often can't adjust the descending height of the evaluation instrument when in use, and the scope of use is limited, At the same time, when the survey device is working, due to the unstable fixation, it will cause the survey device to move, which will make the survey and evaluation results of the survey device inaccurate
