Controllable grouting material for advanced small pipe for water-rich accumulation body stratum tunnel and preparation method thereof
The invention relates to a controllable grouting material for an advanced small pipe for a water-rich accumulation body stratum tunnel. The controllable grouting material is prepared from cement pasteand additives (polyethylene glycol, sodium hydroxide, silica sand and lignosulfonate). The preparation method comprises the following steps: uniformly mixing water and 42.5
一种用于富水堆积体地层隧道超前小导管可控注浆材料，由水泥浆和添加剂(聚乙二醇、氢氧化钠、硅砂和木质素磺酸盐)制成。其制备方法：将水与42.5#普通硅酸盐水泥均匀混合制成水泥浆；将氢氧化钠与硅砂加入水中均匀混合、溶解，得到溶液A；将PEG‑800固体加入水中溶解，得到溶液B；将溶液A、溶液B和木质素磺酸盐加入到所述水泥浆中充分混合，即得到可控注浆材料。本发明的可控注浆材料在解决了传统注浆材料难以实现的水下抗分散性和可控性的同时，也满足了隧道开挖对于浆材的胶凝时间、早期强度、析水率等性能的要求，在注浆结束后，富水堆积体地层加固效果良好，对环境无污染，节省了造价且满足施工进度要求。
