Abstract

The invention discloses a collapsible loess in-situ detection mechanism, which comprises a frame plate, a cooling device, pressure devices, thick position detection devices and a control system, wherein the cooling device is clamped on the frame plate in an embedded manner, the pressure devices are arranged on the frame plate and can apply downward pressure to the frame plate, the thick position detection devices are arranged below the frame plate, and the cooling device, pressure devices and the thick position detection devices are connected with the control system through data transmission lines. The collapsible loess in-situ detection mechanism is simple in structure, flexible to use, high in measurement precision and high in degree of automation, can directly correct measurement results by the system, can directly guide the design, and significantly improves the working efficiency.

Description

technical field [0001] The invention belongs to the field of detection devices and relates to an in-situ detection mechanism for collapsible loess. Background technique [0002] Collapsible loess is a special soil that undergoes significant additional deformation due to the structural damage of the soil after flooding under the action of the self-weight stress of the overlying soil layer, or under the joint action of the self-weight stress and additional stress. The soil is relatively uniform, loose in structure and well-developed in pores. When not wetted by water, it generally has higher strength and less compressibility. When soaked by water under a certain pressure, the soil structure will be destroyed rapidly, resulting in a large additional subsidence, and the strength will decrease rapidly. Therefore, the study of the collapsible loess thickness is an important work before construction on the loess site, in order to prevent the foundation collapsing from causing dam...
