Cast-in-situ concrete box culvert mould used for comprehensive pipe corridor construction project
Our company design and produce the cast-in-situ concrete box culvert mould for Jianguo road comprehensive pipe corridor construction project.
The steel mould adopts the mould structure similar to the tunnel platform, the side mould of the straight line adopts the double side door frame hanging slide type, which greatly improves the construction quality and construction efficiency.
In particular, cast-in-situ concrete box culvert with a no -pair rod it can be used to design for the straight line segment, which can greatly improve the waterproof quality of the main body and improve the construction efficiency.
The total length of pipe corridor is about 4.2km, located at the west side of the road, and the middle line of the tube is 22m.
