titleOfInvention | Post-grouting grout and grouting method for high-strength elastic wall of mechanically connected channel |
abstract | The invention relates to a post-grouting slurry for a high-strength elastic wall of a mechanically connected channel, including liquid A and liquid B. The liquid A components are ultrafine cement and water, and the liquid B components are water glass and polypropylene fibers. , epoxy resins, retarder, flocculant, water reducer and water; the volume ratio of each component of the A and B liquids is 1:1 to 1:0.3, and the weight of each component of the A liquid The proportion is: ultrafine cement 30-50%, and the rest is water; the weight proportion of each component of the B liquid is: water glass 45-50%, polypropylene fiber 0.0-0.1%, epoxy resin 0.0-0.2%, retarder 0.5-3%, flocculant 0.1-0.2%, water reducing agent 0.4-1.0%, and the rest is water. The beneficial effects of the present invention are: compared with the existing simultaneous grouting and secondary grouting of the shield tunnel, the present invention combines the synchronous grouting and the secondary grouting technology into one and is applied to the tunnel wall of the communication channel. Grouting, the slurry has high fluidity, tensile and compressive strength. |
