Integrated mini pile support strip foundation model testing device beside side slope

Abstract

The invention relates to an indoor rock and earth mass model testing device, in particular to an integrated mini pile support strip foundation model testing device beside a side slope, and belongs tothe technical field of geotechnical engineering. The device is composed of a rigid counterforce frame, a hydraulic pump, a force transferring beam, a roller bearing, a guide rod, a force transferringrod, a spherical support, a rigid strip foundation, a mini pile, a suspension rod, a displacement sensor and a specimen preparation box. By means of the integrated mini pile support strip foundation model testing device beside the side slope, the problem about mini pile support simulation under the side slope and foundation coupling condition is solved, a load output system of the integrated minipile support strip foundation model testing device beside the side slope is reliable, the practicability is high, the device can serve theoretical and support design, and the device can be widely applied to side slope and foundation interactional model testing under the mini pile support condition.

Description

technical field [0001] The invention relates to an indoor rock and soil mass model test device, more particularly relates to a strip foundation model test device beside a side slope integrated with micro-pile support, and belongs to the technical field of geotechnical engineering. Background technique [0002] In recent years, under the background of the rapid development of my country's infrastructure construction, sometimes affected by factors such as terrain and economy, it is necessary to embed the foundation on the foundation next to the slope. For example, mountainous roads are limited by terrain, so roadbeds need to be set on the foundation next to the slope; when bridges cross valleys or traffic lines, sometimes pier foundations need to be set on the top of the slope; tower foundations of transmission lines in mountainous areas are often set on the side slope Adjacent to the foundation; when open-pit mining, sometimes the roadbed is temporarily buried on the foundati...

AI Technical Summary

Problems solved by technology

[0005] However, there are few model tests on the existing strip foundations next to the slope, and the load eccentricity problem often exists when the foundation is loaded, especially after the foundation is overturned and damaged. Consider the model test equipment for supporting micro-pile support

[0006] To sum up, the theoretical and experimental research on the bearing capacity and system stability of strip foundations next to slopes is still insufficient, and there is no targeted model test equipment for micropile support, and the development of slopes with integrated micropile support The side strip foundation model test device can provide important technical support for revealing the interaction mechanism and stability control of the complex system composed of slope and foundation
