Prefabricated drainage box culvert manufacturers, rainwater box culvert components, power box culverts and special assembly and disassembly equipment for disassembly and assembly of mobile molds, precast concrete box culverts eliminate the need to remove molds and lift steel molds, reduce the number of cranes used, and help speed up the box Production of precast concrete box culverts, Beijing drainage box culvert manufacturers, rainwater box culverts, power box culverts, which are equipped with a number of vibrator holders 13 for fixing the vibrator, and the precast concrete box culvert operating platform 9 is set on the side mold 3 Upper end. The end mold 2 has a rectangular frame structure, and corner modules are provided at four corners inside the frame. The end mold 2 is formed by finishing, and the end mold 2 is horizontally moved and disassembled by special equipment on the end mold disassembly and assembly chute 6. The prefabricated concrete box culvert avoids damage to unstrengthened components and improves the accuracy of finished components. The inner mold 4 is a door-shaped structure as a whole, which is composed of an upper horizontal module and two vertical modules. Prefabricated concrete box culverts are used less, and prefabricated concrete box culverts account for a large proportion of foreign underground pipelines, which are widely used in engineering. . There are specialized chemical plants producing box culverts in Japan. Precast concrete box culverts are mostly used in large flood discharge channels, urban rain and sewage pipes, underground pedestrian passages, and underground tunnels for motor vehicles. Precast concrete box culverts are currently used in China to make box culverts. Prefabricated prefabricated box culverts have short construction period, good quality of precast concrete box culverts, good integrity, strong resistance to foundation settlement and earthquake, and good for the environment Features such as small impact and broad application prospects in the field of highway construction.
