Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model, for installing the instrument of photoelastic taseometer, comprises sleeve 1 and mounting rod 2 as shown in Figure 1, sleeve 1 is the hollow cylinder body of both ends open, sleeve 1 internal diameter is 52mm, thickness of pipe 4mm, sleeve 1 length is 1.5m, mounting rod 2 is by mobile jib 3, photoelastic taseometer mounting head 4 and sand-cement slurry mounting head 5 form, mobile jib 3 is right cylinder, length is 1.5m, external diameter is 52mm, mobile jib 3 one end is threaded connection photoelastic taseometer mounting head 4, photoelastic taseometer mounting head 4 external diameter is 50mm, protruding right cylinder 6 is provided with in the middle of photoelastic taseometer mounting head 4, protruding right cylinder 6 diameter is 8mm, length 15mm, photoelastic taseometer mounting head 4 entirety is wrapped up by rubber peel 7, mobile jib 3 other end is threaded connection sand-cement slurry mounting head 5, the external diameter of sand-cement slurry mounting head 5 is 52mm.
