Auxiliary shield mud formula for shield construction and production process thereof
The invention relates to the technical field of auxiliary shield mud formulas, in particular to an auxiliary shield mud formula for shield construction and a production process thereof, and the auxiliary shield mud is mainly prepared by mixing bentonite, an additive and water; the additives comprise hydroxypropyl methyl cellulose ether, sodium citrate, a strong alkali-resistant penetrant, a strong acid-resistant penetrant, xanthan gum, carrageenan, calcium carbonate and sodium carbonate; during use, the use effects of supporting a bottom layer and achieving sealing and pressure maintaining are achieved during tunneling, the problems that in the prior art, due to the fact that cement is adopted, the sealing effect is poor, and the pressure maintaining performance is poor are solved, the cement is in a colloidal state during use, and during use, the problem that in the prior art, when cement is adopted, formwork fixing needs to be adopted for a long time is solved. And the production period of solidification of the cement is shortened, so that the progress of subsequent processing is enhanced, and the use effect and purpose of sealing and pressure maintaining during tunneling are achieved.
本发明涉及辅盾构泥配方技术领域,具体涉及一种盾构施工用辅盾泥配方及其生产工艺,包括以下物质:所述辅盾泥主要由膨润土以及添加剂配合水混合组成;所述的添加剂包括:羧丙基甲基纤维素醚、柠檬酸钠、强耐碱性渗透剂、强耐酸性渗透剂、黄原胶、卡拉胶、碳酸钙和碳酸钠;在使用时实现了对掘进是,保证底层的支撑以及起密封保压的使用效果,避免了现有技术中起采用水泥使得起密封效果差以及起保压性,并且其使用时成胶状,在使用时避免了现有技术中采用水泥时起需要长时间采用模板固定,使其凝固的生产周期,从而加强了起后续加工的进程,从而实现起对掘进时的密封保压的使用效果与目的。
