1. Product introduction
JH-VⅡ type cast-in-place pile fluidization enhancer is a multi-functional enhancer specially used in pile foundation engineering. The product not only has water reduction enhancement, moderate setting time, good plasticity retention and construction It has the characteristics of good workability, and greatly improves the performance of concrete such as freeze-thaw resistance, corrosion resistance and prevention of alkali-aggregate reaction. The product has a large expansion efficiency, which can cause the concrete to expand greatly, causing the soil around the pile to be squeezed in the axial and radial directions, increasing the friction resistance around the pile and the bearing capacity of the pile tip, thereby effectively improving the single Pile bearing capacity and reduce single pile settlement. Mixed with about 10% JH-Ⅶ type cast-in-place pile fluidizing agent, the bearing capacity of a single pile can be increased by more than 15%, and the settlement of a single pile can be reduced by about 20%; mixed with 15% JH-Ⅶ type fluidizing agent, the single pile bearing capacity The strength can be increased by more than 80%, and the settlement can be reduced by about 80%. The product also has good water reduction and enhancement effects, obvious retarding effects and good slump-preserving effects, and can improve the workability, pumpability and pourability of concrete. performance, reduce bleeding and stratification, and improve the quality of the pile body.
2. Dosage and usage
For concrete with 32.5# cement as the base material, the product dosage is 10% of the cement dosage; for concrete with 42.5# cement as the base material, the product dosage is 10-15% of the cement dosage, generally no need to add other external admixtures. The product is suitable for various types of ground foundation cast-in-place pile projects, and can also be used for dry powder spray pile and deep mixing pile projects.
10% of JH-Ⅶ type cast-in-place pile fluidization enhancer to be added in the Fuyang relocation project, and the bearing capacity of the single pile is increased by more than 15%. The use results of many pile foundation projects such as the Huaneng Power Plant in Shenzhen Industrial Park show that the product has obvious technical advantages and significant economic benefits.
