Abstract

The invention discloses a spatial isolation type runway pavement underlying goaf treatment method and relates to goaf treatment in the fields of mining engineering, civil engineering, traffic engineering and the like. The goaf treatment method aims to solve the problem that the number of underlying excavation roadways is large, and the roadways may be communicated with one another. A plurality of investigation sections are arranged by excavating, digging and investigating a level, it is guaranteed that a reinforcing project is totally within a determined goaf range, an isolation structure is arranged on the boundary of a continuous goaf, and therefore it can be guaranteed that all reinforcing filler is added and diffused within a definite range. The method overcomes the defect that slurry flows in disorder under unrestrained conditions in a conventional grouting filling goaf, and consequently it is difficult to guarantee that the slurry is effectively diffused within a definite range.

Description

Technical field:

[0001] A space-isolated method for treating mined-out areas under pavement, which relates to the treatment of mined-out areas in fields such as mining engineering, civil engineering, and traffic engineering. Background technique:

[0002] In recent years, with the continuous development of my country's national economy, the requirements of economic construction for the transportation system have been continuously improved, and the construction of expressways and railways has also advanced at an unprecedented speed. Due to the increasingly dense road network, highways and railways in some areas inevitably need to pass through or build on the surface of old goafs, especially in some areas where there are many mines mined by civilians, the situation of random mining is serious, and Most of the mining data are not systematic, the distribution of goafs is disorderly, and there is a situation that goafs are connected with each other. If the underlying mined-out a...
