Sign is, when the raw material after mixing being put into hydraulic press molding in the step 1, the briquetting pressure of hydraulic press is 200Mpa,
Briquet after molding carries out hydrothermal hardening processing, and the environment of processing uses hydrothermal reaction kettle, and reaction temperature is 200 degrees Celsius,
Reaction time is 12 hours.
6. a kind of steel slag according to claim 1 manufactures sponge urban water-through concrete road engineering paving process, special
Sign is that the cross-sectional width of diversion bed course in the horizontal direction is identical as the road width after molding in the step 2, diversion
The two sides of bed course are provided with greenbelt, and the water flow of diversion bed course drainage can enter in the soil of greenbelt bottom.
7. a kind of steel slag according to claim 1 manufactures sponge urban water-through concrete road engineering paving process, special
Sign is, stone bed course is filled in the flow guide recesses in the step 2, and stone bed course is made of coarse sand, can be made by coarse sand
Water flow flowing is more smooth, reduces the risk of water flow obstruction.
8. a kind of steel slag according to claim 1 manufactures sponge urban water-through concrete road engineering paving process, special
Sign is that the thickness of step 3 medium coarse sand is identical as the thickness of fine sand in the step 4.
9. a kind of steel slag according to claim 1 manufactures sponge urban water-through concrete road engineering paving process, special
Sign is that the thickness of fine sand is 15cm-50cm in the thickness of step 3 medium coarse sand and the step 4.
10. a kind of steel slag according to claim 1 manufactures sponge urban water-through concrete road engineering paving process, special
Sign is, when flattening base road surface using land leveller in the step step 5, needs substantially to flatten base road surface,
Then pavement-height difference carries out heavy type and rolls reality, the planarization and using effect on road surface can be improved within 10cm.
