Move, eliminate safe hidden trouble；
(2) it can prevent from colliding with each other between landing slab after landing slab is fixed, damage caused by reducing component fatigue, carry
Service life of equipment is risen, reduces maintenance cost；
(3) keeper is fixed on buttress by retention bar, and keeper is firmly connected with buttress, and locating part is firm resistance to
With highly reliable；
(4) end of landing slab is fixed between location-plate and buttress by location nut, and locating part is simple in construction, peace
Dress is convenient；
(5) full-automatic production, efficiency high, demoulding time foreshorten to 20-30 minutes, production capacity lifting 10 by 15-20 hours
More than times；
(6) production process clean environment firendly, no waste water, without solid waste, without dust；
(7) in the case of landing slab equality strength, binder materials 10%-20% is saved, material cost is lower, lifting production enterprise
Industry benefit；
(8) steam curing is used, high-early-strength, in the case of identical gel material content, 3 days intensity improves 40-50%, and 28
Its intensity improves 20-30%；
(9) because the pressure technique ratio of mud that shakes is 0.1-0.15, the ratio of mud is low, and compactness is high, good endurance, coagulation pedosphere
Face transition region significantly improves, and component compactness and internal cementing strength are largely increased.
