The invention relates to a continuous cold-rolling and steaming dyeing process and equipment of an active dyestuff. The continuous cold-rolling and steaming dyeing process comprises the following steps: 1, padding the dyestuff; 2, steaming and fixing color; 3, soaping; 4, carrying out acid washing; 5, softening and fixing color; 6, squeezing and drying. In the step of padding the dyestuff, the active dyestuff and a color fixing auxiliary agent are prepared separately; in an active dyestuff preparation process, a penetration auxiliary agent is added; the prepared active dyestuff and the color fixing auxiliary agent are mixed online and then are added into a dyeing vat; the temperature of a dyeing solution in the dyeing vat is controlled to be 0 to 10 DEG C and the time for padding the dyestuff is 4s to 8s; a small-capacity dyeing vat is adopted as the dyeing vat and the updating period of the dyeing solution is 8min to 15min; a sewing body, yarns or textiles pass through a plurality of groups of rollers in the dyeing vat for a plurality of times of squeezing and pad dyeing. The continuous cold-rolling and steaming dyeing process and equipment of the active dyestuff have the beneficial effects that continuous type dyeing is carried out; the production efficiency is greatly improved and the labor intensity is alleviated; the consumption of energy sources and resources including water, power, steam and the like is also greatly reduced and the environment pollution is further reduced.

The invention discloses a construction method and device for jacking continuous construction beams for railway box culverts. Excavating and pouring continuous construction beams excavate hole pile foundations, excavating prefabricated pits; prefabricating box culverts; elevating existing railways and Reinforcement, that is, to erect crossbeams first, and then erect multi-section longitudinal beams connected together on both sides of the railway to form a longitudinal beam system. The longitudinal beam system is supported on On the ground, the longitudinal beam lifts and fixes the beam and the railway rail, and the longitudinal beam is bolted with high-strength bolt groups; the prefabricated box culvert is jacked, and the box culvert section is placed on the top of the box culvert section every time it is jacked. Set up temporary piers on the side with temporary excavated pile piers, and remove the temporary excavated pile piers on the side of the box culvert section, and carry out the jacking of the next box culvert section until all box culvert sections Jacking up to the designed position; backfill the top of the separated box culvert and goafs at both ends, remove the convenience beams and temporary buttresses, and restore the line.

A continuous solid-liquid mixing and granulating apparatus is composed of tower-type main body with hollow mainshaft, motor, speed regulator, granulating head with spray hols, and built-in scavenger. The mixture of molten material and microparticles is sprayed out from said granulating head and then solidified.
