The method is that short-fiber rough yarns A and B recoiled from two rough yarn blocks are fed in parallel between two electrostatic spinning areas formed between a feeding roller and a rough yarn lifting rack; the two areas are provided with loudspeaker-shaped receivers which rotate at a certain of speed and driven by motors to collect nano fibers; the two loudspeaker-shaped receivers respectively rotate to form airflows; the nano fibers C and D are driven by electric field power to spirally deposit on receiving rings of the two oudspeaker-shaped receivers; a nano fiber bundle C deposited under the driving of the airflows is combined with the rough yarns A flowing through the loudspeaker-shaped receivers; a nano fiber bundle D is combined with the rough yarns B flowing through the loudspeaker-shaped receivers; the two rough yarns respectively drive each nano fiber to enter in parallel into rear stretching twisting devices; two multi-component combined yarns are guided out through front rollers and combined at a combining point and then twisted again, and finally the rough yarns pass through a steel wire rope through yarn guide hooks to coil the fine yarn blocks with self rotating power.

The invention relates to a high-strength concrete composite expanding agent for a steel tube and a preparation method thereof. The high-strength concrete composite expanding agent comprises the raw material by weight percentage as follows: 30-50% of light calcined magnesium oxide, 8-30% of calcium oxide, 30-60% of zeolitized crushed crude pearlite, and 0.1-0.3% of industrial stearic acid. The water demand for hydration of light calcined magnesium oxide is small in use level, and the light calcined magnesia has the delayed expansion performance and can compensate volume shrinkage of concrete at an older age. The calcium oxide is fast to hydrate and can compensate self-shrinkage and cooling shrinkage of concrete in an earlier stage. The zeolitized crushed crude pearlite can improve the working performance of concrete, so that concrete has good peaceability, and calcium oxide and magnesium oxide expanding components are distributed uniformly in the concrete, so that the problem of nonuniform expansion of concrete is solved.
