Joints of Concrete Manhole

Joints between the manhole elements are almost the same with concrete pipes, there are flat joints, as well as male & female joints. The seals for the gap are cement plaster, factice, and rubber seal.

Concrete Manhole Manufacturing

There are ways to manufacturing concrete manhole, by dry cast vibration machine and wet cast manual mold. are the most common two methods.

Wet Cast Manhole Mold

Wet cast manhole mold uses the steel mold to manufacturing precast manholes, using wet concrete as aggregate, the finished manhole will cure inside the mold until it becomes solid to remove the mold. This mold is suitable for Low-Rate Initial Production.
