Embodiment Construction
[0023] The earth pressure gauge embedding device includes the grouting pipe 13 of the high-spray grouting machine, the earth pressure gauge 1, the reaction force frame 2, the centralizer 10, the positioning key 11 and the guide positioning key 12. The reaction force frame 2 is made up of a reaction force plate 4, an upper frame plate 6 and a lower frame plate 3, and the upper frame plate 6 and the lower frame plate 3 are respectively welded on the reaction force plate 4 to form an integral structure. The earth pressure gauge 1 is fastened on the lower frame plate 3 at the lower end of the reaction force frame 2 through bolts and nuts. After the earth pressure gauge 1 and the reaction force frame 2 are assembled, it is necessary to ensure that the length direction of the reaction force plate 4 is consistent with the force surface of the earth pressure gauge. Vertical to reduce the interference of the pressure plate 4 on the measurement of the earth pressure gauge. The counterfo...
