Early-strength capillary crystalline grouting material for filling lining cavity of operating tunnel and preparation method of grouting slurry
The invention discloses an early-strength permeable crystallization type grouting material for filling lining holes of an operating tunnel and a preparation method of grouting slurry. The grouting material comprises the following components in parts by weight: 650-850 parts of Portland cement; 100 to 200 parts of a rapid hardening agent; 5-10 parts of fumed silica; 3-6 parts of a water reducing agent; 0.2 to 0.5 part of a stabilizing agent; 0.2 to 0.5 part of a plastic expanding agent; 50 to 100 parts of a shrinkage-compensating expanding agent; 0.2 to 1 part of a retarder; 0.3 to 0.8 part of a defoaming agent; and 5-15 parts of a capillary crystalline agent. The early-strength capillary crystalline grouting material for filling the lining cavity of the operating tunnel is high in flow state, micro-expansive, good in cavity filling property, high in early strength and excellent in capillary crystalline waterproof effect, meets the construction requirements of filling and repairing the lining cavity of the operating tunnel, and has a good treatment effect on water leakage of lining concrete.
本发明公开了一种运营隧道衬砌空洞填补用早强渗透结晶型注浆材料及注浆浆体的制备方法，该注浆材料包括如下重量份数的组分：硅酸盐水泥650‑850份；快硬剂100‑200份；气相二氧化硅5‑10份；减水剂3‑6份；稳定剂0.2‑0.5份；塑性膨胀剂0.2‑0.5份；补偿收缩膨胀剂50‑100份；缓凝剂0.2‑1份；消泡剂0.3‑0.8份；渗透结晶剂5‑15份。本发明的运营隧道衬砌空洞填补用早强渗透结晶型注浆材料高流态、微膨胀，空洞填充性好，早期强度高，具备优良的渗透结晶防水效果，满足运营隧道衬砌空洞填补修复施工要求，同时对衬砌混凝土渗漏水有很好的治理效果。
