Below in conjunction with accompanying drawing, to of the present utility model, for measuring the single point extensometer of stope roof strata displacement, be described further.
Accompanying drawing explanation
Fig. 1 is that the utility model is for measuring the scheme of installation of the single point extensometer of stope roof strata displacement.
Embodiment
As shown in Figure 1, the utility model comprises anchor head 5 for measuring the single point extensometer of stope roof strata displacement, sponge 7, Grouting Pipe 8, displacement transmission lever 9, pipe adapter 10, PVC protection tube 11, measuring staff 12, displacement meter sensor 13, cable 14, thin wire 15, hand-held readout instrument (not shown), displacement transmission lever 9 is connected in sequence by pipe adapter 10 by a plurality of steel pipes, anchor head 5 comprises mechanical anchor fluke and is connected to the latch of mechanical anchor fluke lower end, the lower end of latch is connected with the upper end of displacement transmission lever 9, thin wire 15 passes from displacement transmission lever 9, the upper end of thin wire 15 is connected with the axle of mechanical anchor fluke, and the lower end of displacement transmission lever 9 is stretched out in the lower end of thin wire 15, and sponge 7 is positioned at latch lower end, be sleeved on the outside surface of displacement transmission lever 9, Grouting Pipe 8 is stretched out sponge 7 upper surfaces through the upper end of sponge 7 and Grouting Pipe 8, the lower end of displacement transmission lever 9 connects the upper end of measuring staff 12, PVC protection tube 11 is sleeved on the outside surface of the junction of displacement transmission lever 9 and measuring staff 12, and the lower end of measuring staff 12 connects hand-held readout instruments by cable 14.
During use, first the boring 3 ' that diameter is 60-70mm of constructing vertically upward in the rock mass 1 ' of strata movement observation chamber 2 ', then the anchor head of the single point extensometer assembling and displacement transmission lever are stretched in boring, arrive after predetermined depth, anchor head will be arranged on the cement-roll 4 ' bursting of upper end in boring in advance, break thin wire, latch promotes mechanical anchor fluke opens mechanical anchor fluke simultaneously, and now the overall weight of single point extensometer is born by the friction force of mechanical anchor fluke; After cement-roll 4 ' solidifies, cement-roll 4 ' is combined anchoring with mechanical anchor fluke, bears overall weight; By Grouting Pipe, carry out slip casting again, sponge outer wall and drill hole inner wall fit, and slip casting can not dropped before solidifying under Gravitative Loads; Grouting Pipe is moved down, continue, to slip casting in boring, to make PVC protection tube and rock stratum anchoring, now the weight of displacement transducer is born by the slip casting after solidifying.The displacement of rock stratum gets off via anchor head, displacement transmission lever, measuring staff transmission, in displacement transducer transfer, turn to electric signal, then through cable, be delivered to hand-held readout instrument, can read, preserve measurement result, also measurement result can be transferred in computing machine and preserve.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
