Green inorganic tough TBM (Tunnel Boring Machine) backfill grouting material and application thereof
The invention discloses a green inorganic tough TBM (Tunnel Boring Machine) wall post-grouting material and application thereof. The TBM wall post-grouting material is prepared from the following components in parts by weight: 50 to 70 parts of cement, 30 to 50 parts of fly ash, 5 to 10 parts of desulfurized gypsum, 5 to 10 parts of bentonite, 0.1 to 0.5 part of water reducing agent, 0.05 to 0.1 part of defoaming agent, 0.05 to 0.1 part of thickening agent, 5 to 20 parts of waterborne polyurethane emulsion, 0.1 to 2 parts of modified glass fiber and 40 to 60 parts of water. According to the invention, all the raw material components are synergistically used, so that resource utilization of wastes is realized, environmental pollution is reduced, the overall performance and durability of the grouting material are improved, and a more reliable material basis is provided for shield engineering.
本发明公开了绿色无机韧性TBM壁后注浆材料及应用，TBM壁后注浆材料包括按重量份计的如下组分：水泥50‑70份、粉煤灰30‑50份、脱硫石膏5‑10份、膨润土5‑10份、减水剂0.1‑0.5份、消泡剂0.05‑0.1份、增稠剂0.05‑0.1份、水性聚氨酯乳液5‑20份、改性玻璃纤维0.1‑2份、水40‑60份。本发明通过各原料组分协同使用，不仅实现了废弃物的资源化利用，减少了环境污染，同时提高了注浆材料的整体性能和耐久性，为盾构工程提供了更可靠的材料基础。
