Shield synchronous grouting material suitable for water-rich karst stratum
The invention belongs to the field of shield synchronous grouting materials, and particularly relates to a shield synchronous grouting material suitable for a water-rich karst stratum. The shield muck concrete mainly comprises the following components in parts by weight: 10-20 parts of cement, 20-30 parts of fly ash, 5-8 parts of quick lime, 40-60 parts of shield muck, 30-40 parts of water, 1-2 parts of accelerator polyaluminum sulfate, 0.1-0.2 part of optional one of four materials including anti-dispersing agent hydroxyethyl cellulose, hydroxypropyl methyl cellulose, hydroxyethyl cellulose ether and xanthan gum, and 0.1-0.3 part of sodium naphthalene sulfonate formaldehyde condensate. The synchronous grouting material can adapt to shield construction of the water-rich karst stratum, and has relatively high scouring resistance and environmental protection performance.
本发明属于盾构同步注浆材料领域，具体为一种适用于富水岩溶地层的盾构同步注浆材料。其成分主要包括水泥10‑20份、粉煤灰20‑30份、生石灰5‑8份、盾构渣土40‑60份、水30‑40份、速凝剂聚合硫酸铝1‑2份、抗分散剂羟乙基纤维素、羟丙基甲基纤维素、羟乙基纤维素醚、黄原胶四种材料任选一种，含量0.1‑0.2份、萘磺酸钠甲醛缩合物0.1‑0.3份。该同步注浆材料能够适应富水岩溶地层盾构施工，具有较强的抗冲刷性和环保性能。
