Flexible frame anchor device and self-monitoring method thereof

Abstract

The invention discloses a flexible frame anchor device and a self-monitoring method thereof. The flexible frame anchor device comprises an upper frame beam, a lower frame beam and an anchor cable, wherein the lower frame beam is set at the bottom of the upper frame beam, a compression spring and a measuring device are set between the upper frame beam and the lower frame beam, the compression spring can adjust deformation and pressure to obtain better protection effect, the external display of the measuring device can carry out real-time monitoring and early warning, grouting holes are equippedon the upper frame beam, the device can be sealed by grouting to improve the protection effect, and the device is fixed on a side slope by the anchor cable. The self-monitoring method provided by theinvention is simple and effective. After the construction and installation of the device, the initial data in the measuring device and the data after the operation period or rainfall are collected tocalculate a deformation value of the side slope, and then the deformation value is compared with the design value to monitor whether there is a risk of landslides at the side slope. The invention hasa simple structure, safety and reliability, and low production cost, can be applied to various soil and rock side slopes, and has broad engineering application prospects. The self-monitoring method of provided by invention is simple and the monitoring and early warning effect is good.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a flexible frame anchor device and a self-monitoring method thereof. Background technique [0002] Landslide refers to the soil or rock mass on the slope, affected by factors such as river scouring, groundwater activity, rainwater soaking, earthquake and artificial slope cutting, under the action of gravity, the soil or rock mass moves along a certain weak surface or weak zone. , the natural phenomenon of sliding downhill as a whole or scatteredly. The mechanism of the landslide is that the shear stress on a slip plane exceeds the shear strength of the plane. Landslide is a common natural disaster caused by engineering geological problems, which mainly occurs in mountainous areas and river valleys. Landslides may cause mountain collapse. If heavy rain occurs after the landslide, the resulting debris flow will cause serious damage to the building facilities and people's...

Problems solved by technology

Once a landslide disaster occurs, the consequences will be very serious. It will cause direct damage to infrastructure such as road damage, communication interruption and house burial. At the same time, it will endanger the safety of life in the disaster-affected area and affect the normal life of nearby residents. Economic loss also seriously damages the surrounding ecological environment
