Problems solved by technology

[0004] The technical problem to be solved by the present invention: for the current traditional method of strengthening river embankments, most of them use cement and fine sand to mix and reinforce the river embankment as a whole. Although the cost is low, the reinforcement layer is easy to crack and the foundation is not firm. Or heavy rainfall, will not be able to effectively block the defects, providing a method of gluten oyster shell fermented product tamping bentonite to reinforce the embankment

example 1

[0021] First, take the flour and water according to the mass ratio of 2:1, mix and knead the dough into a dough, put the dough into a wooden bucket, add water to the wooden bucket until the dough is completely submerged, scrub the dough manually, and wait until the water in the bucket becomes Change the water again when it is milky white, continue to rub the dough until the dough becomes smaller and the milky white water can no longer be washed out, filter the residue and steam it in a steamer for 15 minutes to obtain gluten powder; then weigh 2 tons of oyster shells and place them in a grinder for 2h , Obtain the crushed oyster shells, put the crushed oyster shells into a rotary kiln to heat up to 1200℃, heat preservation and calcination for 5 hours to obtain quicklime, weigh 120kg of the obtained quicklime and soak in 350kg of water for 40min, filter with gauze to remove sand and stone impurities , Get lime oil; chop 200kg sugarcane and put it in a juicer to squeeze the juice,...

Abstract

The invention relates to a method for reinforcing a river wall through gluten oyster shell leavening compacted bentonite, and belongs to the technical field of foundation treatment. Oyster shells are burnt firstly to obtain quick lime, the quick lime and a large amount of water are mixed and filtered, lime oil is obtained, the lime oil, gluten meal, waste newspaper and cane syrup are mixed and fermented to obtain paper reinforcement pulp with the great viscidity, the characteristics of plasticity and bondability of an admixture of bentonite and water or mud or fine sand are used, a reinforcing base material is formed, and is compounded with paper reinforcement pulp, the rich active group on the surface of the paper reinforcement pulp and hydroxide radical on the surface of the reinforcing base material are used for generating hydrogen bond suction and chemical bonding force, plasticity and bondability are further improved, and the effect of compacting a reinforcing layer is achieved. Under washing of heavy rainfall, the reinforced river wall is not prone to cracking, the obvious reinforcing effect is achieved, the large amount of cement is avoided, the oyster shells and the waste newspaper and the like serve as raw materials, the resources are recycled, cost is saved, and the reinforcing method is simple and easy.

Description

Technical field [0001] The invention relates to a method for tamping bentonite to strengthen river embankments with fermented gluten oyster shells, and belongs to the technical field of foundation treatment. Background technique [0002] In order to improve the anti-scouring and anti-seepage capabilities of the river dikes of water conservancy projects, so as to achieve the construction purpose of eliminating dangers and strengthening, some measures are often taken to eliminate dangers and strengthen the river embankments. This guarantees the eradication of many dangerous problems in the dangerous sections of the river. The normal use of water conservancy projects is very effective. The strength of the embankment foundation soil is the main factor affecting the overall stability of the embankment, especially the embankment on the silt foundation. Due to the high natural moisture content of the silt, the large natural void ratio, low shear strength, high compressibility and low pe...
