Supporting and fixing device for fixing GNSS instrument

Abstract

The invention provides a supporting and fixing device for fixing a GNSS instrument. The supporting and fixing device comprises a main telescopic rod and a lower supporting device. The GNSS instrumentis installed at one end of the main telescopic rod, the other end is connected with the lower supporting device; the lower supporting device comprises four branch telescopic rods which are evenly distributed in the circumferential direction of the main telescopic rod. A supporting structure is arranged at the free end of each branch telescopic rod. The device is convenient to carry, easy and convenient to assemble and disassemble, retractable, more flexible to use, capable of being leveled, capable of freely adjusting the height of the instrument and capable of monitoring factors such as windpower and wind direction and soil stress state in real time; meanwhile, compared with the traditional PVC pipe, the overall stability of the device is better through the installed hole expanding and soil expanding impact grabbing cone.

Description

technical field [0001] The invention belongs to the field of slope construction technology, and in particular relates to a supporting and fixing device for fixing a GNSS instrument. Background technique [0002] The problem of geological disasters caused by slopes has always been one of the issues of great concern in the process of engineering construction. In recent years, accidents of excessive deformation of high slopes triggered by earthquakes, rainfall, and excavation have occurred in many places in my country, and sometimes even lead to large-scale landslides. , mudslides, seriously endangering people's lives and property safety. Slope deformation detection technology has been developed rapidly in recent years. It has played an important role in ensuring the stability of the slope, verifying the effect of supporting measures, and improving the level of early warning and forecasting of the slope. At present, in the detection technology of mine engineering slope deforma...

AI Technical Summary

Problems solved by technology

[0005] 1. At present, PVC pipes are used to support and fix GNSS instruments in the project. In order to make the support stable, cement concrete is poured into PVC, and steel bars are added to increase its self-weight. However, it consumes a lot of materials and is uneconomical.

[0006] 2. The PVC pipe material is not strong, easy to age, and has poor corrosion resistance and weathering resistance. After pouring concrete, if the length of the support is very long, it will cause the top to shake greatly due to external forces, which will lead to abnormal test results. large error

[0007] 3. The currently used device only plays the role of fixing and supporting the GNSS, and it is not convenient to carry, cannot be retracted, and is not flexible enough to use, and cannot freely adjust the height of the instrument

[0008] 4. When installing the instrument, it is often affected by the working environment and human influence, which makes the installed support structure shift and tilt, which in turn affects the construction process and wastes materials

[0009] 5. After the actual instrument is installed, it only plays a supporting role, but does not get multi-functional utilization
