Reconnaissance device for evaluating collapsibility of foundation

Abstract

The invention discloses a reconnaissance device for evaluating collapsibility of a foundation, and relates to the technical field of foundation evaluation. The reconnaissance device comprises a power device, a descending device, an extrusion device, a fixing device and a bottom device, the descending device and the fixing device are both arranged at the top of the bottom device and fixedly connected with the bottom device, and one side of the fixing device extends into the descending device and is in sliding connection with the descending device; and the power device is arranged at the top of the descending device and fixedly connected with the descending device, and the extrusion device is arranged on the side face of the descending device and abuts against the descending device. According to the reconnaissance device, by arranging the descending device and the extrusion device, the descending height of an evaluation instrument can be adjusted, so that the descending height of the evaluation instrument can be adjusted according to actual requirements, the application range of the whole device is expanded, and the practicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of foundation evaluation, in particular to a survey device used for evaluation of foundation collapsibility. Background technique [0002] After the loess is wetted by water under a certain pressure, the structure is rapidly destroyed and the performance of significant additional subsidence is called collapsibility. It is a unique engineering geological property of loess. The most fundamental reason for the collapsibility of loess is that it has obvious water connection, weakens the structure and tends to be compact, and is conducive to collapsibility. The collapsibility of loess can be divided into self-weight collapsibility and non-self-weight collapsibility. type, the former refers to the phenomenon that the loess has little subsidence under its own weight after being exposed to water; the latter refers to the additional subsidence that occurs under the additional load after the loess is soaked in water....

AI Technical Summary

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
