Plastic early strength type shield tunnel synchronous grouting material and preparation method thereof
The invention relates to a plastic early-strength shield tunnel synchronous grouting material and a preparation method thereof. The synchronous grouting material comprises the following components in parts by weight: 260-340 parts of a base material; 5.1-8.2 parts of an early strength stabilizer; and 150 to 250 parts of water. The base material is prepared from the following components in parts by weight: 25 to 50 parts of ordinary Portland cement, 20 to 40 parts of sulphoaluminate cement, 50 to 80 parts of mineral powder, 10 to 20 parts of silica fume, 100 to 160 parts of fly ash and 50 to 80 parts of machine-made sand. The early strength stabilizer comprises the following components: triethanolamine, calcium chloride, water glass and cellulose ether. The early strength stabilizer endows the base material with the early strength characteristic, the uniformity and stability of the grouting material are improved, the plastic early strength type shield tunnel synchronous grouting material is prepared and obtained, the material is used in urban subway shield tunnel synchronous grouting engineering, segment floating can be effectively controlled, and the service life of the grouting material is prolonged. And safe and efficient shield construction under the water-rich condition is achieved.
本发明涉及一种塑性早强型盾构隧道同步注浆材料及其制备方法。同步注浆材料，按重量份计，包括以下组分：基体材料260‑340份；早强稳定剂5.1‑8.2份；水150‑250份。基体材料，按重量份计，包括以下组分：普通硅酸盐水泥25‑50份，硫铝酸盐水泥20‑40份，矿粉50‑80份，硅灰10‑20份，粉煤灰100‑160份，机制砂50‑80份。早强稳定剂，包括以下组分：三乙醇胺、氯化钙、水玻璃和纤维素醚。本发明通过早强稳定剂赋予了基体材料早强特性，并提高了注浆材料的均匀性与稳定性，制备获得了塑性早强型盾构隧道同步注浆材料，材料用于城市地铁盾构隧道同步注浆工程中，可有效控制管片上浮，实现富水条件下盾构安全高效施工。
