Abstract

The invention discloses a geotextile filled geotube interlamination tangential dislocation and displacement measuring device. The measuring device comprises an upper protective shell, a lower protective shell, a sliding protective shell, T-shaped sliding blocks, a displacement sensor and sliding grooves. The upper protective shell is provided with a containing cavity for containing the displacement sensor. The fixed support end of the displacement sensor is fixedly connected with one end of the lower protective shell. The movable rod end of the displacement sensor and one end of the upper protective shell are fixed. The top end of the sliding protective shell is fixedly connected with the inner surface of the upper protective shell. The upper ends of the T-shaped sliding blocks are fixed in the sliding protective shell. The two sides of the lower protective shell are provided with the parallel sliding grooves in the direction of the displacement sensor. The sliding grooves are connected with the lower ends of the T-shaped sliding blocks in a matched and sliding mode. The measuring device is easy and convenient to mount, free of influencing dam construction, capable of measuring the tangential dislocation and displacement directly in the measuring process and convenient to use, the safety monitoring cost is lowered, the negative effect on the environment is extremely low, and it is guaranteed that a dam brings up social and economical benefits and the like.

Description

technical field [0001] The invention relates to a displacement measurement device, in particular to a displacement measurement device for horizontal displacement between layers of geotextile filled tube bags, and belongs to the technical field of safety monitoring. Background technique [0002] Reclamation and embankment engineering has undergone fundamental changes from traditional riprap dams to modern mud-sand filled pipe bag dams, from dam construction materials, dam construction techniques, design theory methods, analysis and calculation principles, to risk, safety assessment techniques, etc. . Carry out monitoring research on the safety of reclamation dams during the construction and operation periods based on the pipe-bag bare dam as the embankment core. Through the monitoring of typical sections, the operational behavior of general dams can be grasped quantitatively, and provide analysis for the safe operation of the entire dam project in accordance with. The monit...
