The key points in bridge construction are caught in the net!

Every detail in bridge construction is very important. This paper will share the main beam length, hanging basket construction, pouring skills and other key points to help you better understand the bridge construction.

How to determine the length of main girder?

The determination of the main girder length is related to the girder form, span, pier width, hanging basket form and construction period. The length of section 0 is generally 5~20m, and the length of suspension casting section is mostly 3~5m.

Construction skills of hanging basket

Hanging basket installation is no joke! Safety first, stability first, and reliability is the key. In the hanging basket construction, every detail needs careful design and calculation to ensure the safety and stability of the construction.

Pouring technique

It is best to pour the whole section of the pier top beam at one time, but if the beam section is too high, it can be poured twice. Remember that the height of the first pouring should exceed the top surface of the bottom plate by at least 500mm, and the time difference between the two concreting should be controlled within 7 days.
