Accompanying drawing explanation
With detailed description of the invention, the present invention is described in further details below in conjunction with the accompanying drawings.
Fig. 1 is general assembly structural representation of the present invention.
Fig. 2 is general assembly structural profile schematic diagram of the present invention.
Fig. 3 is that strip of the present invention interts bolt structure schematic diagram.

Detailed description of the invention
General assembly structural representation as shown in Figure 1, is made up of base 1, slump cone 2, column with holes 3, scale column 4, location nut 5, fixing feeding hopper supporting ring 6.
Strip interts bolt structure schematic diagram as shown in Figure 3, strip intert screw 7 and wing nut 8 is constituted.
1) first with wet cloth wetting slump cone, feeding hopper, Water collecting tube barrel and bottom surface and other apparatus, it is desirable to soak and without open fire.Base is placed on solid horizontal plane, with long spiro nail, slump cone and base is fixed together, slump cone is laid feeding hopper.
2) dividing 3 layers to be uniformly charged in cylinder mixed concrete mixture sample scuppit on request, after making tamping, every layer of specimen height is about 1/3 that cylinder is high.Every layer plugs and pounds 25 times with tamper.Should be carried out to center by periphery along the hand of spiral when plugging and pounding, plug and pound every time and should be uniformly distributed on cross section.When plugging and pounding the concrete sample on a limit, tamper can be slightly tilted；When plugging and pounding bottom, tamper should run through entire depth；When plugging and pounding the second layer and top layer, tamper should be inserted through this layer to the surface of next layer.During pouring top layer, concrete mix should be filled at feeding hopper 2/3, after top layer plugs and pounds, scrape off unnecessary concrete mix floating with spatula.
3), after removing the concrete on the base of cylinder limit, slump cone is the most smoothly mentioned.The raising process of slump cone should complete in 5 ~ 10s.Should complete in 150s from the whole process starting to be charged to mention slump cone.
4) after mentioning slump cone, slump scale on mobile column immediately, concrete mix examination body peak after making scale lower edge and collapsing is equal, and the lower limb connecting ring from vertical rod reads scale (in units of mm), and this numerical value is the slump value of this concrete mix.
5) height of liquid level in observation Water collecting tube, according to the color region at liquid level place, it is determined that concrete water-retaining property.As liquid level is starched and aggregate exposure because flowing at the part concrete mix of higher color region or cone, then concrete water-retaining property is poor；If liquid level is in lower region, then show that water-retaining property is good.
6), after slump cone lift-off, as examination body collapses or cuts up phenomenon, then should resample is measured.As second time this phenomenon still occurs, then it represents that this mixture workability is bad, should give record for future reference.
7) after measuring and record the slump, water-retaining property, impact gently at the mixture pyramid side collapsed with tamper, if cone is gradually sunk, represent that mixture sticks poly-property good；If cone is decayed, part is burst apart or isolation occurs, i.e. stick poly-property poor.
8) do not reach requirement when the slump recording mixture, the ratio of mud can be kept constant, increase by cement and the water of 5% or 10%；When the slump is excessive, sand coarse aggregate ratio can be kept constant, take the circumstances into consideration to increase sand and the consumption of stone；Such as glutinous poly-property or poor water retention property, then need suitably to adjust sand coarse aggregate ratio.After adjusting, mix is uniform as early as possible every time, re-starts the slump and measures.
The above is the preferred embodiment of the present invention, it is impossible to limit the interest field of the present invention with this.It should be pointed out that, for those skilled in the art, technical scheme is modified or equivalent, without departure from protection scope of the present invention.
