Mounting, burying and grouting method for multi-point displacement meter

The invention discloses a mounting, burying and grouting method for a multi-point displacement meter. According to the mounting, burying and grouting method, holes are drilled in rock stratums of different conditions, and the displacement meter is mounted at multiple points. The mounting, burying and grouting method comprises the steps of rock stratum displacement monitoring in the horizontal direction, in the vertical direction, in the slanted upward direction and in the slanted downward direction. A double grouting method is adopted in the displacement meter, namely, the displacement meter is provided with a vent pipe, a far-end anchor head, a near-end anchor head and double grouting pipes. The mounting, burying and grouting method for the multi-point displacement meter can be applied to displacement safety monitoring in building projects and construction such as water conservancy and hydropower projects, highways and railways, the problem that the grouting of the multi-point displacement meter is insufficient under different rock stratum conditions is solved, the rock mass deformation of the measured part can be reflected truly by the displacement meter, and reliable monitoring data are supplied to the buildings.
