Abstract

The invention relates to a processing method applied to an urban underground goaf, which is characterized in that according to different spatial information of the goaf and a specific processing boundary, a reasonable grouting process is adopted to grout the goaf, so that the goaf is effectively filled, and the strength of the goaf is enhanced. Interference or influence of the goaf on normal construction is avoided, and safety accidents such as collapse, settlement or deviation after construction is completed are also avoided. According to the method, the spatial information of the goaf is acquired, corresponding processing is carried out according to the spatial information of the goaf and the processing boundary, the surrounding environment is not greatly influenced, the method is suitable for construction under urban environment conditions, the goaf processing cost is low, the engineering adaptability is good, and secondary collapse of the goaf in the construction process can be avoided.

Description

technical field [0001] The invention relates to the technical field of infrastructure construction, in particular to a processing method applied to an urban underground goaf. Background technique [0002] With the continuous development of the city, the scope of its radiation has become wider and wider, so that the resource mining areas that originally belonged to the suburbs will be incorporated into the city scope, for example, the original coal mining areas will be incorporated into the city scope. Since the original resource mining area will leave the corresponding goaf after the mining is completed, it will cause great trouble for the subsequent construction of subway and other underground transportation. The traditional treatment methods for the goaf are mine mining, water conservancy project basic treatment, etc. Among them, some of the mine mining processes require ground blasting, which is not suitable for urban environmental conditions; the water conservancy projec...
