In order to solve the problem of jaw crusher concrete wedge base, has made a number of improvements and try, such as the secondary grouting layer on top of a layer of steel, to solve the problem of secondary grouting layer wear: Another example in times the grout layer and reinforced in order to address the problem of the secondary grouting layer cement blocks easy to break, but eventually did not achieve satisfactory results. Later rubber elastic pad instead of the wedge, the rubber elastic pad cushion between the contact surface of the base floor and the second filling layer 3 using this program, jaw crusher concrete wedge base exists a good solution to good effect. Its production method: (1) the first anchor bolts unloading loose all.
(2) select 4 suitable jack (must afford to the top of the main body), the top of the body is about 180mm. ③ the secondary concrete grout layer (wedge "All Clear clean. (4) in the original secondary grouting position installed 8mm steel mesh, steel mesh height of less than 80mm (steel bars into strengthening the secondary grouting layer anti- pull effect, to prevent secondary grouting layer prone to rupture). ⑤ in pouring 500 # cement concrete (plus accelerator for concrete rapid solidification), laying reinforcement secondary grouting layer the concrete height control is about 150mm. (6) concrete immediately after pouring lower the height of the four jack (not more than 1 hour, the time is too long, the rapid solidification of concrete cause does not fit, and second, because of the rapid solidification of the concrete the secondary grouting is not strong), the use of body weight will the secondary grouting concrete laminated to 150mm thick, at the same time pay attention to adjust the level of the body and around the work is completed with pillar firmly fixed body position, and completely avoid body lowering and mobile, fixed concrete coagulation (7) concrete after solidification, and then the four jacking up equipment body, the underside of the body leaving the secondary grouting layer about 50mm the ⑧ will pre-made rubber elastic pad insert pad in the second filling layer with the body between the bottom.
⑨ pad good rubber elastic pad, slowly release the four jacks, equipment equilibrium pressure on top of the rubber elastic pad, adjust the equipment around, and finally tighten all anchor bolts, day after boot downtime will tighten the anchor bolts all over again. In this way, the jaw crusher concrete rubber elastic pad base can be safely used for many years.
