Description
Real engineering cost is lower than the similar span bridge, culvert
Short construction periods, mainly for assembling construction
Use of standardized design, production, simple design and short production cycle
Production is not affected by environment. Large-scale factory production, lower costs, quality control
Installation without the use of large equipment, convenient installation
Reduction of cement, gravel, sand and other pieces of rubble or dosage, is favorable for environmental protection
Be helpful for improving soft soil, expansive soil, collapsible loess and other special foundation structures of uneven settlement problem, improve the road service performance, reduce post-construction maintenance cost
Solve the problem of cold northern regions (Frost) on the destruction of the bridge concrete structures
