Technology of Combination of Prefabrication and Post-pouring Joints Instead of Casting-in-situ for Construction of Arc Wave Walls

The block wave wall of Dongying Port Economic Develop Area bulwark engineering is designed as in-situ concrete.With the restriction of dike width,pavement and other the processes intersect job,cast-in-place process can′t guarantee the construction period,besides construction concrete in winter season can cause the quality problems of concrete.Change the cast-in-place into part of the cross-sectional prefabricated blocks,the construction technology of pouring through two gear wave wall sections and design of segment long construction,a mass of concrete constructions are concentrated in the precast yard,reduces embankments time,and improves efficiency,provides ample work surface for the construction of other processes.Adopting technology of flipping alignment in shipping,which greatly reduces the common quality problems of the concrete wave wall surface cover,ensures the concrete quality of appearance.
