Construction of an underground space development NEAR DIFFERENTIAL RELIEF

摘要

The utility model is applicable for the private civil engineering structures on the part of the slope, rehabilitation of underground structures, building underground part of an existing building. The essential features of the model is the location of use: significant difference relief space, and a method for creating slab by drilling the horizontal slots in the ground with a casing, followed by pumping under pressure the concrete. Thus, in the ground created a strong underground floor, serving the ceiling during the subsequent work. Unlike existing analog device design eliminates the use of temporary fasteners ceiling and walls of the face area in the restricted areas, dramatically reducing operational safety, the local rapid reinforcement of the walls and ceiling of the additional racks as dredging produced under established ceiling. The design allows the use of earth moving equipment, which speeds up the work.
