Problems solved by technology

[0007] The above-mentioned first and second kinds of production process of colored pavement materials are complex and costly, and the color of colored pavement materials is not bright enough and not durable enough; Simple, colorful and long-lasting
However, this kind of pavement material is often different from the basic pavement material, and when the temperature changes greatly, there will be pavement damage caused by different expansions.

Embodiment 1

[0076] The mold of the pavement combination sticking block of this embodiment is provided with nine mold cores 2 arranged in 3 rows and 3 columns, and the shapes of the mold holes and the mold cores are circular. The orifice area of ​​the die hole is 80cm 2 , The thickness of the template is 30mm, the length of the core 2 extending into the die hole is 10mm, and the distance between two adjacent die holes is 2mm. The design template 1, the fixed plate 3, and the bottom plate 4 are all square, and the connecting rods 6 are each provided at the four corners of the bottom plate. See above for other structures.

Embodiment 2-5

[0077] Example 2-5: Preparation of cement

[0078] Cementing materials were prepared according to the materials and compositions shown in Table 1, and cementing materials A1, A2, A3, and A4 were obtained corresponding to Examples 2-5.

Embodiment 6

[0082] Add 10kg alumina powder, 0.75kg calcium carbonate powder, 0.1kg dye (iron oxide red) into 20kg water, ball mill for 4h to obtain the first slurry, and then add the first slurry to 200kg of alginic acid with a concentration of 1.5wt% In the sodium solution, stir evenly to form a second slurry with a solid phase content of 4.7%, where the solid phase content in the second slurry = solid phase powder mass / total slurry weight, solid phase powder mass = alumina powder mass + Calcium carbonate powder quality + dye quality, total slurry weight = solid phase powder quality + sodium alginate solution quality.

[0083] Add 2.5 kg of gluconolactone powder to the second slurry, then stir it evenly, and let it stand at 40°C for 48 hours to obtain the first gel. Among them, because the gluconolactone powder slowly releases H from the mouth + Therefore, there is no obvious gel phenomenon during the stirring process, but the gel is gradually formed in the static process, so as to ensure t...

Abstract

The invention discloses a method and mould for preparing a pavement combined adhering block. The mould comprises a template, a plurality of mould cores, a fixed plate, a bottom plate, a screw and a connecting rod; the template is located above the fixed plate, a plurality of through mould holes are formed in the template, one ends of the mould cores are formed in the fixed plate while the other ends extend into the mould holes; the bottom plate is located below the fixed plate and is provided with a threaded hole, one end of the screw penetrates through the threaded hole and the screw sleeves a bearing, the bearing is embedded into the lower portion of the fixed plate, and the screw is in screw-thread fit with the threaded hole of the bottom plate; a through hole is formed in the fixed plate, and one end of the connecting rod is connected to the bottom plate while the other end of the connecting rod penetrates through the through hole and is connected to the template. The mould can prepare a plurality of brick blocks at one time and the brick blocks are connected as a whole through a linking layer, so that the pavement combined adhering block is obtained. As two adjacent brick blocks are separated from a certain distance, pavement damage caused by thermal expansion can be avoided.

Description

Technical field [0001] The invention relates to a method and a mold for preparing a pavement combined paste block. Background technique [0002] The colored pavement has the function of beautifying the environment and warning traffic. Colored pavements are widely used in Europe to remind road users which part of the road can be used at which time. Colored pavements are widely used in Europe to provide a separate lane for special road users, such as bus lanes dedicated to public transportation, bicycle lanes, small motor vehicle lanes, and electronic toll stations dedicated to emergency services and VIP card holders. Lane. Color roads are distinguished by color in some speed bumps. This distinction is very practical. It can effectively reduce traffic violations and increase traffic safety. In addition, the popularization of colored pavements can greatly change the image of the city and reflect the characteristics of the city. It is not only reflected in the changes in the ap...
