Two new bridge construction methods suit for less girders and long working period

Below two bridge construction methods suit for highway and high speed railway bridge with less concrete girders and long working period.

1. cast-in-situ concrete girders on two piers, namely MMS, pour one piece of girder on two piers, 1 week later move forward to produce another girder, girder weight 650t or 900t or 1000t, it is divided into MZ series upstroke movable scaffolding system and MSS series downstroke movable scaffolding system. The construction method suits highway and high speed railway projects with less concrete girders, long working period.
2. Segments assembly then integral tension method on piers. Pre-fabricate concrete segments in advance in pre-cast yard, then transport segments to proper position so that segments assembly launching girder can bond and install all segments in one span, then tension the whole span before erection of the next girder. The construction method suits highway and high speed railway projects with less concrete girders and long working period, especially suits to construct above the river. HZP series launching girder and girder carrier are necessary in above working condition.
