VARIABLE BOARDING AND FIXINF APPARATUS FOR UNDERGROUND CAVITIES DETECTOR OF UNDER A RAILWAY

The present invention relates to a variable boarding and fixing device for a joint exploration device under a track, and more particularly, a joint exploration device under a track for use when moving along a railroad track and exploring whether a cavity or sinkhole under the track is formed. It relates to a variable boarding fixture for use.

In the soil structure section with a lot of soil on the track, there is concern about the occurrence of subsidence of the track ground due to the following factors.

First of all, it is a case of soil and soil flowing into the water pipe due to the damage of the water pipe buried underground.

And, it is a case where a void is generated under the line due to some cause due to construction such as underpass.

And, it is a case where a void is generated under the line due to the influence such as leakage of groundwater.

Therefore, in order to visually observe under the track, it is necessary to conduct a test excavation, and it is difficult to find a dangerous place before sinking.

Here, as a method for exploring a dangerous location, it is said that electromagnetic wave radar exploration that is not limited by the type of buried object is effective.

As equipment for the exploration of cavities or sinkholes under the road surface, it is possible to explore using a system such as "System and method for rapid detection of ground subsidence" (Prior Art 1) of Registered Patent No. 10-1793830, but It is difficult to apply the prior art 1 to the railway road surface.

In addition, although it is possible to explore the condition of railway tracks by using a device such as the "rail condition inspection robot" (prior art 2) of Patent Registration No. 10-1300063, the prior art 2 has a large limitation in the cost to prepare it in the initial stage. .

Therefore, there is an urgent need to develop a device that can be applied to railway tracks as well as equipment for general under-road cavities or sinkholes, such as those of the conventional prior art 1 .
