Can dismantle and tunnel that precision is high convergence monitoring couple

The utility model discloses a can dismantle and tunnel that precision is high convergence monitoring couple, including protecting a section of thick bamboo and convergence tray, protect and fill the anchor agent between a section of thick bamboo and the country rock, protect being provided with the barb thorn on the section of thick bamboo and making and protect a section of thick bamboo and closely link to each other with the country rock, warp unanimously, protect to be provided with on the section of thick bamboo and protect the cover, protect the inside draw-in groove that is provided with of a section of thick bamboo, the convergence tray through the draw-in groove with protect a section of thick bamboo and link into an integrated entity, be provided with the convergence couple on the convergence tray and be connected with convergence meter couple, can protect the tube length degree and protect a deformation condition of the different degree of depth country rocks of draw-in groove position monitoring through the adjustment, be provided with compression spring in the convergence tray, after the monitoring task was accomplished, the accessible was stirred spring plectrum compression spring and then is taken out the convergence tray to be used for the sectional monitoring of next monitoring. Adopt the utility model discloses, the collision that can avoid construction machinery to get in touch the convergence reduces monitoring personnel's the duplication of labour, improves the control measurement accuracy, avoid the corruption of groundwater to geting in touch, improve the life of couple, the convergence tray can repeat the practicality and then reduce the monitoring cost.
