Application of vacuum grouting in Rongqiao bridge;

Vacuum grouting technique is a new technology in the construction of post-tensioned concrete.

Prestressed construction technology of the box girder concrete of the bridge and the vacuum grouting technology;

For the example of Luohe Bridge,the paper introduced the applications of vacuum grouting technique to Lijun Expressway.

Connecting with the experiences of the grouting construction of prestressed continuous RC beam, this paper expounds the advantages, construction techniques, methods and existing disadvantages of vacuum grouting.

The vacuum mud jacking is the new technology in a pre-stressed construction concrete structure,and it has been already more and more widely applied in the project practice.

Uses the plastic corrugated pipe and the vacuum mud jacking construction craft is the new craft which south the Xiamen success main road rotary island road multi-level crossing bridge superstructure box Liang constructs, the union tradition construction craft introduces this new craft the merit and the scene construction method.

The article mainly discusses the principle,advantages and construction technology of the vacuum mud-jacking technique,and the gist of the construction control,and probes into the hole mud-jacking technique of post-tensioned prestressed structure of the round tank wall.

The dense yittria-stabilized zirconia and alumina membrane tube was prepared using pyridine as dispersant by vacuum casting, which the thickness of the membrane was 0.
