Grouting double-locking pressure real-time sensing system and method for operating the same

A grouting double-locking pressure real-time sensing system, comprising:

• a positioning structure (1), an expandable positioning structure (2), a pressure real-time monitoring component (3), and a grouting structure (4);
• wherein the positioning structure (1) is fixed to a ground;
• the expandable positioning structure (2) passes through the positioning structure (1), and an input end of the expandable positioning structure (2) is connected to the grouting structure (4);
• and the pressure real-time monitoring component (3) is connected to the expandable positioning structure (2) for monitoring a pressure in a grouting hole and a supply pressure of a grouting equipment, wherein the pressure real-time monitoring component (3) also feeds information to a receiver;
• and
• wherein the expandable positioning structure (2) comprises a hollow conduit (21), an expandable assembly (22), an upper positioning member (23), and a lower positioning member (24);
• wherein the upper positioning member (23) and the lower positioning member (24) are respectively connected to two ends of the expandable assembly (22);
• the hollow conduit (21) passes through the upper positioning member (23) and the lower positioning member (24), and is threaded to the upper positioning member (23) and the lower positioning member (24);
• the upper positioning member (23) is fixed to the positioning structure (1);
• a thread direction of the upper positioning member is the same as that of the lower positioning member;
• a thread pitch of the upper positioning member is smaller than that of the lower positioning member;
• portions of the hollow conduit with which the upper positioning member and the lower positioning member are threaded are provided with thread pitches to fit the upper positioning member and the lower positioning member;
• and when rotating the hollow conduit (21), the lower positioning member (24) moves up and down, so as to expand or contract the expandable assembly (22).
