Abstract

The present invention discloses an underground space data monitoring device, which relates to the field of tunnel measurement technology, and includes a top pressure detection mechanism, a bottom pressure detection mechanism and a data analysis mechanism. The top pressure detection mechanism and the bottom pressure detection mechanism both include a cover plate, a pressure sensor, a first sleeve and a disassembly and assembly component. The cover plate is arranged at one end of the first sleeve, and the cover plate penetrates into the soil layer. The pressure sensor is arranged on the cover plate through the disassembly and assembly component, and the output end of the pressure sensor abuts against the cover plate. The data analysis mechanism is used to analyze the data detected by the pressure sensor; and convert the pressure detected by the top pressure sensor and the bottom pressure sensor into a pressure difference and compare it with the standard top pressure and bottom pressure difference that the tunnel can withstand during construction. The staff analyzes whether the tunnel has a tendency to sink through the data in the data detection mechanism, and can thus promptly agree on a solution.
