Good-durability supporting mud for shield tunneling machine
The invention discloses good-durability supporting mud for a shield tunneling machine, which comprises the following components in parts by weight: 55-85 parts of silicate supporting mud clinker, 12-32 parts of carbide slag, 12-32 parts of gypsum, 6-16 parts of fine sand, 5-10 parts of slag, 11-31 parts of ash, 12-15 parts of manganese slag and 5-10 parts of a modifier. The modifier comprises the following components in parts by weight: 2-11 parts of hydroxide of alkali metal, 12-32 parts of soluble carbonate, 17-42 parts of aluminate, 2-7 parts of citric acid, 22-37 parts of fly ash, 20-35 parts of gangue and 1-2 parts of an enhancer. The hydroxide of alkali metal in the modifier reacts with gypsum in the supporting mud to generate soluble sulfate and calcium hydroxide, so that the gypsum loses the delayed coagulation effect. Due to the fact that the concentration of the gypsum in the solution is reduced, C3A rapidly enters the solution to separate out hydrates, and the supporting mud is rapidly cured.
本发明公开了一种耐久性好的盾构机用支撑泥，所述支撑泥包含以下重量组份：硅酸盐支撑泥熟料55‑85份，电石渣12‑32份，石膏12‑32份、细沙6‑16份、矿渣5‑10份、灰渣11‑31份、锰渣12‑15份，改良剂5‑10份，其中改良剂中各组份的重量份组成如下：碱金属的氢氧化物2‑11份，可溶性碳酸盐12‑32份，铝酸盐17‑42份，柠檬酸2‑7份，粉煤灰22‑37份，矸石20‑35份，还包含强化剂1‑2份。本发明改良剂中碱金属的氢氧化物与支撑泥中的石膏反应生成可溶性硫酸盐以及氢氧化钙，使石膏失去缓凝作用，由于溶液中的石膏浓度的降低，C3A迅速进入溶液析出水化物，导致支撑泥浆迅速固化。
