Embodiment

[0047] The method for monitoring rock formation displacement based on belt drive of the present invention, concrete steps:

[0048] (1), determine the installation position of the base point anchor: according to the geological properties of the rock formation to be monitored, determine the installation position of the base point anchor 1, the installation position of the base point anchor 1 includes the installation position of the deep base point anchor 15 (including installation height or installation depth) and the installation position of the shallow base point anchor 16 (including installation height or installation depth), use a drill bit slightly larger than the outer diameter of the sleeve 2 to drill holes to meet the installation requirements of the deep base point anchor 15;

[0049] (2), install the deep base point anchor: loosen the take-up box 4 of the steel strand 11 corresponding to the deep base point anchor 15 to tie the wires, and use the installation guide ro...

Abstract

The invention discloses a stratum displacement monitoring method based on belt driving and belongs to the field of stratum displacement monitoring technologies. The method aims to solve the technicalproblems of how to avoid stratum displacement measurement data errors caused by equipment and improve stratum displacement measurement precision. Through the method, it is convenient to manually observe and record stratum displacement values, and meanwhile linear displacement can be converted into rotating angular variables and provide conditions for performing processing and remote monitoring forelectric signal conversion. According to the adopted technical scheme, the method comprises the steps that (1) installation positions of base-point anchors are determined; (2) a deep base-point anchor is installed; (3) a shallow base-point anchor is installed; (4) a sleeve is positioned; (5) the belt position is standardized; and (6) stratum separation displacement is read, wherein when a stratumseparates and generates displacement, steel strands drive a belt to move through a connecting sliding block, and displacement length is directly read through scale values on the belt.

Description

technical field [0001] The invention relates to the technical field of rock formation displacement monitoring, in particular to a method for monitoring rock formation displacement based on belt transmission. Background technique [0002] There are generally three points (A, B, C) in the monitoring of rock formation displacement, as attached figure 1 As shown, point A is selected in the stable rock formation, which can be considered as a fixed base point, point B is selected in the moving rock formation, and with the movement of the rock formation between A and B, point C is selected on the measurement surface, which is generally the installation point of the monitoring device. The rock formations between BC are mostly anchored with anchoring materials such as bolts. [0003] When the rock formations between BC move relative to each other, the distance between BC becomes larger, which reflects that the length of the steel wire between BC becomes longer, and the increase in l...
