Special grouting material for tunnel grouting construction with mold and application of special grouting material
The invention relates to the technical field of tunnel belt mold grouting construction, in particular to a special grouting material for tunnel belt mold grouting construction and application of the special grouting material. The raw materials comprise 90-150 parts of cement, 20-30 parts of fine aggregate, 26-44 parts of an additive, 20-30 parts of high-calcium fly ash, 5-15 parts of calcined shale, and 30-35 parts of phosphogypsum; the cement is formed by mixing 40 to 70 parts of ordinary Portland cement and 50 to 80 parts of rapid hardening sulphoaluminate cement; by adding the high-calcium fly ash, the calcined shale and the ardealite in a certain proportion, the later strength of the grouting material is improved, so that the stability of the grouting material is improved; the high-calcium fly ash serves as an expansion source of one of the grouting materials and can remarkably improve the later strength, the impermeability and the durability of the grouting materials through the characteristics of the high-calcium fly ash.
本发明涉及隧道带模注浆施工技术领域，具体地说，涉及一种用于隧道带模注浆施工中的专用注浆料及其应用，注浆料由原料加水混合而成；原料包括：水泥90‑150份、细骨料20‑30份、外加剂26‑44份、高钙粉煤灰20‑30份、煅烧页岩5‑15份、磷石膏30‑35份；所述水泥由40‑70份的普通硅酸盐水泥和50‑80份的快硬硫铝酸盐水泥混合而成；通过加入一定比例的高钙粉煤灰、煅烧页岩和磷石膏，有利于提高注浆料的后期强度，从而提高了注浆料的稳定性；高钙粉煤灰作为注浆料其中之一的膨胀源，其能够通过自身的特性显著提高注浆料的后期强度、抗渗性和耐久性。
