Sandy soil curing agent used for water conservancy project soft sinking mattress bottom protection, shore protection, and beach protection

A technology of curing agent and sand, applied in the direction of solid waste management, sustainable waste treatment, climate sustainability, etc., can solve the problem of the integrity of the bottom protection structure and the high requirements for adapting to changes in beach scouring, and the discharge of ballast materials. It should not be too thick, and the firewood riprap bottom protection is unrealistic, so as to achieve the effect of good water flow scouring and soil protection, high anti-lifting and anti-slip stability, and convenient construction.

Problems solved by technology

[0003] Through the investigation of the current status of soft row bottom protection in the Yangtze River area, it is unrealistic to use firewood row and riprap bottom protection. At the same time, due to the poor anti-scourability of the upper soil layer in the project area, the integrity of the bottom protection structure and adaptability to changes in beach erosion The requirements are high, and the ballast material of the discharge body should not be too thick so as not to cause changes in the water flow around the discharge body

Abstract

The invention provides a sandy soil curing agent used for water conservancy project soft sinking mattress bottom protection, shore protection, and beach protection, and a construction method thereof. Production technology of the sandy soil curing agent is simple, and operation is convenient. The sandy soil curing agent comprises 8 to 16wt% of fly ash, 1 to 5wt% of an additive, 1 to 5wt% of gypsum, 1 to 5wt% of sodium sulfate, 0.5 to 3wt% of industrial salt, 0.5 to 3wt% of polycarboxylic acid water reducing agent (or a powder agent), 0.2 to 1wt% of rapid hardening agent A, 0.1 to 0.6wt% of methyl cellulose ether A, 0.1 to 0.6wt% of ethyl cellulose ether B, 0.1 to 0.6wt% of cellulose ether C, and the balance cement. The sandy soil curing agent is capable of maintaining conventional sand rib technical advantages, and functional requirements as an inverted filter, and achieving complementary advantages and realizing perfect combination of hard filling materials with soft geotextile preferably without increasing engineering cost, and realizing soft landing and hard protecting of mattress body authentically and skillfully.

Description

technical field [0001] The invention relates to a sand solidifying agent for water conservancy engineering software sinking, drainage, bottom protection, bank protection and beach protection and a construction method thereof. Background technique [0002] The surface foundation of the area where the Yangtze River deep-water channel improvement project is located is a loose silt layer, and the underlying soil layer is silty soil with high compressibility and low strength. The surface silt layer has the characteristics of fine particles, uniform particle size, and looseness, and is easily lifted and transported by the action of water flow. The construction of building renovation will inevitably lead to changes in the surrounding flow field, which will usually lead to the development of flow along the dike and intensify the scour of the beach beside the dike, thereby endangering the stability of the building. The design and construction of the bottom protection structure to ef...
