Abstract

The invention relates to the technical field of engineering testing equipment, in particular to a model testing device and method for controlling exertion and monitoring of anchor tension. The model testing device for controlling exertion and monitoring of anchor tension comprises a tension sensor for transmitting tension, the tension sensor is arranged inside a fixing frame, the fixing frame is provided with an installation structure connected with a retaining structure, the installation structure is matched with the retaining structure, one end of the tension sensor is provided with a structure for fixing an anchor rope, the other end of the tension sensor is connected with a power transmission mechanism for providing power, the tension sensor is connected with a reading displayer for displaying the magnitude of tension, and the testing device can effectively control the tension exerted to the anchor rope by exerting tension to the anchor rope; meanwhile, the changing situation and changing rules of the tension of the anchor rope are monitored in real time, so that the problem that the changing situation of the tension of the anchor rope is hard to monitor in the prior art is solved, and guidance and basis are provided for the structural stability of an anchor rope slab-pile wall.

Description

technical field [0001] The invention relates to the technical field of engineering test equipment, in particular to a model test device and test method for controlling, applying and monitoring anchor cable tension. Background technique [0002] During the engineering construction process, when the railway or highway passes through the hilly area in the form of deep cutting, due to the weak interlayer between the rock layers on both sides, this rock layer is very prone to landslides or collapses. In order to avoid landslides or collapses, usually The rock stratum is reinforced by anchor cable pile sheet walls to ensure the stability of the cutting slope. In the piled filling construction area, anchor cable pile wall panels will also be used to fix the filling soil. [0003] In engineering construction, the support structure of anchor cable plus pile sheet wall is very common, and it is often used in deep foundation pit engineering and slope support projects. Before choosing ...

AI Technical Summary

Problems solved by technology

In order to effectively observe the change of the tension of the anchor cable and monitor the deformation and displacement of the pile-slab wall when the tension of the anchor cable changes, it is necessary to use a sophisticated test device to measure, analyze and study this process in the laboratory. Due to the difficulty of monitoring the change of the tension of the anchor cable

The main reason is that the anchor cable is fixed in the filling soil, and the tension and change of the anchor cable cannot be monitored. At the same time, the pile-slab wall is subjected to the active earth pressure of the filling soil to make the anchor cable pull, which is a long-term process. It is impossible to pull the anchor cable and measure its force in a short time
