Background
The manufacturing method for molding the conventional pervious concrete standard test piece mainly comprises the following steps: insert molding, vibration molding, static pressure molding, vibration pressure molding and the like. The main method used in the laboratory is vibration molding, and because the vibration strength of experimenters is different, the standard test piece can not reach the operation standard in the manufacturing process, and the condition of force balance is difficult to realize, so that the discrete type of the experimental data of the standard test piece is too large, the referential property is not available, and the complete geological burette control closed loop is difficult to carry out.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a forming and sealing mould for a permeable concrete standard test piece, which can ensure that the permeable concrete standard test piece can reach the standard during manufacturing.
The utility model provides a sealed mould of concrete standard test piece shaping permeates water, is including the mould box that is the cube form, and the mould box has the ascending shaping chamber of an opening, and the shaping chamber top is equipped with the sliding closure that can seal on the mould box, and the top surface of mould box, bottom surface and along the outer wall of direction of height go up the range of clearance have the horizontal limit of multiunit extension, and the periphery that the horizontal limit of each extension all followed the mould box sets up.
The utility model provides a foundation for the 'six-side vibration' method of the pervious concrete standard test piece by sealing the mould box body and the sliding cover, so that each surface of the pervious concrete standard test piece can be uniformly stressed when the vibration table vibrates, the phenomenon of slurry sinking is avoided, the discreteness of the experimental data of the pervious concrete standard test piece is reduced, the reliability of the experimental data is effectively ensured, and the utility model has the advantages of simple structure and convenient operation.
Additional features and advantages of the utility model will be set forth in the detailed description which follows.
Drawings
FIG. 1 is a schematic structural view of a mold box according to the present invention;
fig. 2 is a schematic structural view of the sliding cover of the present invention.
Detailed Description
Referring to fig. 1, the sealed mould of concrete standard test piece shaping that permeates water that this embodiment provided, including the mould box 1 that is the cube form, mould box 1 has the ascending shaping chamber 2 of an opening, combine fig. 2, shaping chamber 2 top is equipped with the sliding closure 3 that can seal on mould box 1, the top surface of mould box 1, the bottom surface and along height direction's outer wall upward clearance range have multiunit extension horizontal limit 4, each extension horizontal limit 4 all sets up along the periphery of mould box 1, be connected with the extension between the extension horizontal limit 4 and indulge the limit 5, the extension horizontal limit 4 with the extension is indulged and is the I shape between the limit 5 and arrange.
In this embodiment, a concrete operation method of the pervious concrete standard test piece forming sealing mold is as follows:
the method comprises the following steps: selecting a known or preset pervious concrete mixing proportion, weighing a proper amount according to the experiment requirement according to the selected coarse aggregate, cement, water, an additive, a mineral admixture and the like, and mixing;
step two: adding a concrete mixture into the molding cavity 2, wherein the concrete mixture occupies 2/3 of the molding cavity 2, placing the bottom surface of the mold on a vibration table for primary vibration for 15s, filling the remaining gap with the concrete mixture, vibrating for 15s, flattening by using a spatula, and covering a sliding cover 3;
step three: putting other five surfaces of the die as bottom surfaces on a vibration table for vibration in sequence, wherein each surface is uniformly stressed and vibrated for 10s to realize tap compaction;
step four: and opening the sliding cover for 3 hours, and removing the mold for natural maintenance after 24 hours.
In the vibration process, because the setting of the horizontal limit 4 of extension and the extension vertical limit 5, judgement that can be very convenient, six faces (after covering sliding closure 3) of mould box 1, every bottom surface is whether level (when out of level) at the horizontal direction, the top surface of mould box 1, the limit of the horizontal limit 4 of bottom surface extension openly can not paste completely at the shaking table, the limit side of the horizontal limit 4 of remaining face extension can not paste completely at the shaking table, wherein, it should be noted that, the width of the horizontal limit 4 of top surface extension of mould box 1 need be less than the horizontal limit 4 width of extension of other places, aim at, need leave the abdicating that is used for covering sliding closure 3, when making sliding closure 3 when assembling the horizontal limit 4 of the extension of mould box 1 top surface, can be rather than the horizontal limit 4 parallel and level in vertical direction of extension.
In addition, because the cooperation setting of extension horizontal limit 4 and extension vertical limit 5 can play certain support and stable structure's effect, makes every bottom surface keep the level when the horizontal direction, and the extension horizontal limit 4 that is the I shape and arranges moreover can disperse concrete mixture self gravity with extension vertical limit 5, has the steadiness height, long service life's advantage.
The six faces of the adopted 'six faces vibrate' to ensure that each face of the pervious concrete standard test piece can be uniformly stressed when the vibration table vibrates, so that the discreteness of the experimental data of the pervious concrete standard test piece is reduced, the reliability of the experimental data is effectively ensured, the phenomenon that the pervious concrete standard test piece is sunk in the manufacturing process can be avoided, and the porosity of the pervious concrete can reach the design value to provide guarantee.
In this embodiment, C-shaped guide rails 31 are provided in both sides and the rear side of the sliding cover 3, and the extended transverse edge 4 of the top surface of the mold case 1 is adapted to the C-shaped guide rails 31. Aim at, adopt this kind of sealed mounting structure, have simple structure, convenient assembling, advantage that stability is high.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
