Method for reinforcing river wall through gluten oyster shell leavening compacted bentonite

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...
