地铁盾构施工同步注浆可硬化浆液
摘要：
一种隧道工程技术领域的地铁盾构施工同步注浆可硬性浆液。本发明组分的重量百分比具体为：水泥7～15％，粉煤灰40～54％，砂15～27％、水22～25％、聚胺类高分子聚合物0.54～0.63％、外掺剂萘系缩合物0.37～0.46％。本发明具有如下性能：浆液稠度值(cm)9.5～11.5，泌水率(％)≤6.0，浆液结实体龄期1～2天达原状土强度，龄期28天达5～9MPa，浆液结实体具有抗震动液化功能，同时具有保水、润滑性，提高泵送能力的作用，使可硬化浆液能更好地满足注浆设备的要求。
摘要（英）：

A subway shielding constructing synchronous slip casting hardening size consists of cement 7-15%, fly-ash 40-54%, sand 15-27%, water 22-25%, polyamine high-molecular polymer 0.54-0.63%, and external adulterant condensation compound 0.37-0.46%. The value of size consistence is (cm)9.5-11.5, bleeding rate(%) <=6.0, it reaches original soil strength when size fecundity age period 1-2 days, and it reaches 5-9Mpa when age period 28 days. Its advantages include good water-retaining property and lubrication, and higher pump delivering ability.
