Abstract

A device for monitoring tower stability and filling soil holes in a karst development area comprises a material pipe, air supply equipment, sand supply equipment and slurry supply equipment, one end of the material pipe is located on the ground and provided with an end cover, the end cover is provided with an air inlet hole and a feeding hole which are communicated with the material pipe, the air inlet hole is communicated with the air supply equipment through an air conveying pipe, and the feeding hole is communicated with the sand supply equipment through an air conveying pipe. A first valve is arranged on the air conveying pipe, the feeding hole is communicated with one end of a sand conveying pipe and one end of a slurry conveying pipe through a material conveying pipe, the other end of the sand conveying pipe and the other end of the slurry conveying pipe are communicated with sand supply equipment and slurry supply equipment, a second valve is arranged on the sand conveying pipe, a third valve is arranged on the slurry conveying pipe, and the other end of the material pipe extends to the position close to a soil hole. Monitoring equipment is arranged on the outer surfaces of the side walls at the two ends of the material pipe and the outer surface of the side wall in the middle and is used for monitoring whether materials exist in the material pipe at the mounting position of the monitoring equipment or not. According to the design, the monitoring accuracy is improved, the construction difficulty is reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a device and method for monitoring the stability of towers and filling soil holes in karst development areas, and is mainly suitable for improving monitoring accuracy and reducing construction cost and construction difficulty. Background technique [0002] One-third of my country's land area is karst geology, and karst soil caves are one of the common types in karst geology, which can easily cause soil layer collapse. In recent years, due to the great demand for electricity, my country's transmission lines have developed very rapidly. The transmission line is inevitably located in the karst development area when the site is selected, and the continuous development of the soil cave has a major hidden danger to the stability of the foundation of the transmission tower. As a carrier of high-load electric energy transmission and an important lifeline project that is one of th...
