Problems solved by technology

[0005] The technical problem mainly solved by the present invention: currently cement and water sand are generally used as raw materials in the reinforcement and manufacture of embankments, not only the cost is relatively high, but also it is easy to crack, resulting in weak foundation, and it will not be effective when encountering floods or heavy rainfall. To block the disadvantages, a method of enzymatically hydrolyzing glutinous rice starch with waste oil is provided to tamp and blow fill soil to reinforce the embankment. In this method, animal fat and the prepared composite liquid mold are mixed and fermented, and then the soaked and softened glutinous rice is steamed. After self-cooling, it is mixed with animal fat and compound liquid mold and then fermented again. Finally, the fermented material is mixed with dredger filling soil and quicklime to build terraced embankments and plant vegetation. This not only reduces the amount of cement used, but also saves costs. Moreover, the reinforcement effect of the material made by this method is remarkable, coupled with the design of the trapezoidal embankment, the truck weighing more than 2 tons can drive stably two days after the embankment is built

example 1

[0028] First put the liquid mold into a high-speed centrifuge for centrifugation, the centrifugation speed is 8000r / min, the centrifugation time is 10min, and the supernatant is separated; then the supernatant and animal fat obtained by the above centrifugation are put into a 1200mL beaker , place it on a magnetic stirrer, adjust the stirring speed to 200r / min, make it stir evenly to obtain a mixed solution, then put the mixed solution into a fermenter, adjust the pH to 6, control the temperature to 28°C, and carry out sealed fermentation for 8 days, Standby; then weigh 5kg of glutinous rice raw material, wash it, soak it in water at 28°C for 0.5h, take it out, add water 2 to 3 times the weight of glutinous rice raw material, adjust the temperature to 100°C, cook for 45min, and wait for it to steam It will become sticky after softening; next, cool the above-mentioned steamed glutinous rice by itself, and stir and mix with the mixture obtained above, adjust the pH to 6.8, contro...

Abstract

The invention relates to a method for reinforcing a riverbank by waste oil, enzymolysis glutinous rice starch and rammed dredger fill, and belongs to the technical field of foundation treatment. The method comprises the following steps: at first, mixed fermentation is conducted on animal oil and prepared compound liquid mold, then glutinous rice which is softened through soaking is cooked, after being automatically cooled, the cooked glutinous rice is mixed with the animal oil and the compound liquid mold and then fermentation is conducted again, and at last, the fermented material is mixed with dredger fill and quick lime to built up a terrace riverbank, and grass and trees are planted on the terrace riverbank. Examples prove that the method is unique and novel, the cement consumption and the cost are reduced, attack of flood or heavy railfall can be blocked effectively, and a truck which is 2-4 t heavy can be stably driven after the riverbank is built up for 2 days.

Description

technical field [0001] The invention relates to a method for enzymatically hydrolyzing glutinous rice starch from waste oil and tamping and dredging filling soil to reinforce embankments, and belongs to the technical field of foundation treatment. Background technique [0002] Embankments are water-retaining structures built along rivers, channels, lakes, coasts, flood diversion areas, and edges of reclamation areas. Building embankments can resist floods, block tides and waves, and protect the safety of residents and industrial and agricultural production inside the embankments. It is the earliest and widely used flood control engineering measure in the world. According to the location of the embankment, it can be divided into river embankment, lake embankment, sea embankment, canal embankment and embankment. Embankments are generally constructed of earth materials. Where rivers pass through cities and towns, reinforced concrete or mortar block stone embankments, also kno...
