Test and Application on New Synchronous Grouting Materials for Earth Pressure Balance Shield

Abstract:

Article Preview

The type and properties of the grouting materials contribute great impact on the grouting effect. The new grout with hydrated lime, fly ash, bentonite, sand, water and water reducer as materials was developed, and the raw material requirements and performance requirements of the new grout were ascertained. Some experimental results were illustrated on the fineness modulus of sand and water reducer dosage impact on the properties of the new grout. The preliminary application results in Shanghai and Soochow metro showed that the new grout played a very good role on the surface subsidence control both in fine clay soil and sand strata.
