Abstract

A grouting double-locking pressure real-time sensing system includes: a positioning structure fixed to a ground; wherein an expandable positioning structure passes through the positioning structure, and an input end of the expandable positioning structure is connected to the grouting structure; the pressure real-time monitoring component is connected to the expandable positioning structure; the expandable positioning structure comprises a hollow conduit, an expandable assembly, an upper positioning member, and a lower positioning member; wherein the upper positioning member and the lower positioning member are respectively connected to two ends of the expandable assembly; the hollow conduit passes through the upper positioning member and the lower positioning member, and is threaded to the lower positioning member; the upper positioning member is fixed to the positioning structure; when rotating the hollow conduit, the lower positioning member moves up and down, so as to expand or contract the expandable assembly.
