Embodiment Construction
[0054] Below in conjunction with specific example, the present invention is further described:
[0055] The subway tunnel of certain shield construction adopts the dry powder type synchronous grouting construction technology of the present invention, adopts the following steps:
[0056] 1. First, produce dry powder type synchronous grouting special mortar;
[0057] 1.1 Determine the mortar mix ratio for dry powder synchronous grouting;
[0058]Fly ash 20%, calcium-based bentonite 3.85%, slaked lime 3.0%, special dry powder admixture 0.15%, sand 73%.
[0059] All materials are powdery materials, calculated by mass percentage;
[0060] Among them, the compounding mass percentage of special dry powder admixture is: methyl cellulose ether 1.1%, naphthalene-based water reducer 33.2%, saponin 0.7%, sodium bentonite 35%, slaked lime 30%;
[0061] The methyl cellulose ether used is hydroxymethyl cellulose ether with a viscosity of 40000;
[0062] The naphthalene-based water reduce...
