description	The invention is applicable to the technical field of trenchless engineering, and provides high-water-retention low-viscosity pipe jacking thixotropic slurry which comprises the following components in parts by mass: 4-8 parts of sodium bentonite, 0.2-0.3 part of sodium carbonate, 1-4 parts of fly ash microspheres, 0.05-0.2 part of welan gum and 85.5-94.75 parts of water. According to the invention, the mixing amount of the sodium bentonite and the admixture is kept at a lower level, so that the material cost can be obviously reduced; and meanwhile, the added welan gum has a very strong water retention characteristic, and the fly ash microspheres are compounded with the welan gum, so that the effects of lubricating and improving the fluidity can be further achieved, the consistency is not influenced, and the grouting resistance is reduced. The pipe jacking thixotropic slurry provided by the invention not only has high water-retaining property and is suitable for underground water-rich stratums, sandy soil and
