Detailed description of the invention
As Fig. 1 is to shown in 5, and a kind of soil cement test block producing device of the present utility model includes base 1, crossbeam 2, column 3, pressure exerting arrangement 4, die holder 5, mould 6 and briquetting 7；Described base 1 is horizontally placed on testing stand or ground, and described crossbeam 2 is fixed on above base 1 by least two root posts 3 being arranged on base 1, makes crossbeam 2 and base 1 keep stable；Described pressure exerting arrangement 4 is installed on crossbeam 2, the telescopic end 8 of pressure exerting arrangement 4 is straight down towards base 1, this pressure exerting arrangement 4 is in order to adapt to different experiment conditions, the cylinder of automatization, hydraulic cylinder can be selected, manual operation can also be selected, i.e. offering vertical internal thread hole 13 on crossbeam, make the screw rod 14 of coupling through this hole, the pressure controlling threaded rod 14 by being fixed on the handwheel 15 at screw rod 14 top exports.As optimizing further, can be in the bottom of described telescopic end 8, the bottom such as the screw rod in cylinder and the underpart of the piston rod of hydraulic cylinder, or manual operation example arranges a pressure head 12, to increase the contact area with briquetting 7, and then increases its stability coordinated.Described die holder 5 is fixed on base 1, and this die holder 5 is cross section elongated slot concavely, and notch is oppositely arranged with the telescopic end 8 of pressure exerting arrangement 4, is positioned at the underface of the telescopic end of pressure exerting arrangement 4.
Described mould 6 quantity is two, it is respectively mold 601 and lower mold 602, two identical and mould 6 width of mould 6 specification size are corresponding to die holder 5 width of rebate, in test block manufacturing process, make mould 6 can block to set and be fixed in die holder 5 groove, limit the displacement of mould 6, keep stability.
The test block damage caused in order to avoid artificial form removal, reach the purpose of machinery form removal, it is respectively arranged with mould on one group of described mould 6 symmetrical outer wall and picks up the ears 9, as preferably, two moulds can be all set pick up the ears 9 by every side outer wall in the outer wall that the one of mould 6 group is symmetrical, this mould picks up the ears 9 to arrange along the short transverse of mould 6, and making mould pick up the ears 9 is I shape with the cross section of mould 6；Mould in lower mold 602 9 times edges of picking up the ears offer groove 10, width between two corresponding grooves 10 is corresponding to die holder 5 width of rebate, in stripping process, lower mold 602 can be made to be fastened on two sidewall upper of die holder 5 by this groove 10, and this design in like manner can make mould 6 in stripping process keep stable.In actual production, it is possible to described groove 10 is offered on the 9 times edges of picking up the ears of the mould at mold 601 equally, makes upper/lower die can mutually replace use.
Described briquetting 7 is column, and cross section is corresponding to mould 6 inner chamber, and height is more than single mould 6 height；It is additionally provided with limiting plate 11 at an upper portion thereof, limiting plate 11 cross section is more than mould 6 inner chamber, so when reaching limiting plate 11 position in briquetting 7 bottom is completely forced into mold 6, pressing force no longer puts on soil cement compound, but born by mould 6, this briquetting 7 separates with device, and in test block making and releasing process, briquetting 7 is arranged between the telescopic end 8 of mould 6 and pressure exerting arrangement 4.
In test block manufacturing process, first lower mold 602, mold 601 are sequentially placed in the groove of die holder 5, two mould 6 consistencies from top to bottom, and make dies cavity be in the underface of device for exerting 4；In mould 6, disposably load mix uniform loose cement soil compound, its surface is struck off, puts briquetting 7 gently so that it is center and pressure head 12 center are on a vertical line；Then the controlling organization of cylinder or hydraulic cylinder is started, promotion piston rod extends, by pressure head 12 by pressure transmission to briquetting 7, then it is transferred on compound, make its dense extrusion, owing to briquetting 7 and test block size are completely the same, highly more than mold 602, and top is with spacing wing plate, so when reaching position-limited wing Board position in briquetting 7 bottom is completely forced into mold, pressing force no longer puts on soil-cement body, but is born by mould 6, in now soil cement compound is then fully pressed into lower mold 602, form satisfactory soil cement test block.Steady pressure is constant, quiet stop 30min after, can slowly shed pressing force, dismantle mold 601 and briquetting 7, the lower mold 602 of remaining band soil cement test block.
In test block stripping process, after lower mold 602 being taken out in the groove of die holder 5, half-twist is positioned over die holder 5 upper end, it is fixed on the upper end of 5 two sidewalls of die holder by the pick up the ears groove 10 on lower edge of the mould of lower mold 602, then the most slowly pressurizeed by pressure exerting arrangement, make test block abjection lower mold 602 slowly, fall within die holder 5, then lower mold 602 is taken and the soil cement test block completed can be taken out.
In another embodiment of the present utility model, it is contemplated that the condition difference in different experiments place, using by rotating the pressure mode that handwheel 15 drives screw rod 14 to press to briquetting 7, remaining manufacturing process is identical, the most too much repeats.Certain pressure exerting arrangement of the present utility model 4 also can be realized by those skilled in the art's other modes thinkable; fixed form to base 1 with crossbeam 2; die holder 5 and the mounting means of base 1; the profile of mould 6 and die holder 5 is made various change; as long as pertaining generally to basic conception of the present utility model, all fall within this utility model scope of the claimed.
