Abstract

The invention discloses a soft soil curing agent composed of a main agent and an adjuvant, wherein the main agent is composed of cements, sands, lime, fly ash, slag cement, gypsum, nanometer silicon based oxides and the like, the adjuvant comprises triethanolamine, calcium lignosulfonate, sodium chloride, magnesium chloride, calcium chloride, ferric chloride, light vanadium or water glass, polyacrylamide, calcium sulfate, sodium sulfate, sodium hydroxide and the like. The invention has the advantage of perfect service effect, and is capable of being used as powder (for dry spraying) or pulp agent (for wet spraying) in cement injection pile construction, and further can be used in constructions of cement mixing pile, grouting, chemical churning pile, shallow layer cushion reinforcement, subgrade strengthening, tamping and the like.

Description

Technical field: [0001] The invention relates to a curing agent for soft soil curing. Background technique: [0002] Existing powder jetting piles, cement mixing piles, and constructions such as subgrade reinforcement and shallow cushion reinforcement are generally simply reinforced with cement or lime, and the reinforcement effect is generally unsatisfactory. Invention content: [0003] The object of the present invention is to provide a soft soil curing agent with good curing effect during soft soil reinforcement construction. [0004] Technical solution of the present invention is: [0005] A soft soil curing agent is characterized in that it is composed of a main agent and an auxiliary agent, wherein the main agent is composed of the following components in weight percentage: [0006] Cement 30-40% [0007] Sand 30~60% [0008] Lime 0~40% [0009] Fly ash 0~40% [0010] Slag 0~20% [0011] Gypsum 0~8% [0012] Nano silicon-based oxide 0~8% [0013] The sum of ...
