Preparation of a geopolymer grouting material and its method for static pressure grouting

Abstract

The invention provides a method for preparing a geopolymer grouting material and a method for applying the geopolymer grouting material to static pressure grouting. Raw materials for preparing the geopolymer grouting material include steel slag, mineral slag, sodium silicate, silica fume, calcium bentonite, softened water and a composite alkali activator. The method for preparing the geopolymer grouting material comprises the steps that 1, a component A is prepared; 2, a component B is prepared; 3, a component C is prepared; and 4, the geopolymer grouting material is prepared. The method for static pressure grouting comprises the steps of 1, survey; 2, assessment; 3, pit sounding; 4, hollowing general survey; 5, deflection value check; 6, comprehensive evaluation; 7, measurement and hole arrangement; 8, drilling; 9, grouting; 10, check; 11, grouting hole sealing; and 12, recheck to complete static pressure grouting. The methods have the advantages of environmental friendliness, low viscosity, high elasticity modulus, high cohesiveness, low cost, high efficiency and high durability.

Description

technical field

[0001] The invention relates to the preparation of a geopolymer grouting material and its method for static pressure grouting. It specifically relates to the reinforcement of roadbed diseases, or the rapid reinforcement of foundations and dam foundations in building construction projects and water conservancy projects, and belongs to civil engineering technology. field. Background technique

[0002] Geopolymer grouting material has attracted much attention due to its non-shrinkage, high strength, fast setting speed and environmental friendliness, and has been applied in the fields of rapid road repair and building foundation reinforcement. It is a rapidly developing grouting treatment technology in recent years.

[0003] However, the two-component grouting material and preparation method disclosed in the patent document CN102702473A have adopted a foaming agent stabilizer and an epoxy resin material as the base material, which has poor durability and low stre...
