Embodiment Construction
[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0056] As shown in the figure, a drilling casing anchorage structure for monitoring cracks in the surrounding rock of the floor includes a floor borehole 2, and the periphery of the floor borehole 2 is the surrounding rock mass 1 of the wall of the borehole. There is a sealed observation tube, and a detection and positioning component is arranged in the sealed observation tube;
[0057] The sealed observation tube includes a plurality of interconnected transparent hollow tubes 8, and the adjacent transparent hollow tubes 8 are connected together by a docking sealing assembly, and the docking sealing assembly includes a docking sleeve 7 and is arranged on both ends of the docking sleeve 7. The two ends of the docking sleeve 7 are respectively set on the ends of the adjacent transparent hollow tube 8, and the two "U"-shaped clips 5 are respectively perpendicula...
