| Abstract: |
| An inflation system for the rubber airbag（referred to as airbag） of the trestle bridge was
designed.According to the usage function，inflation speed and working pressure of the trestle bridge airbag，
the calculations of the equipment parameters and the installation of the pipeline systems for the technical
scheme of the inflation system of the trestle bridge airbag were carried out，and the trestle bridge airbag was
assembled according to the internal structure of the steel structure of the trestle bridge.The water inflation test
showed that it took about 7 minutes to inflate the trestle bridge airbag to the working pressure，which met the
requirements of fast inflation speed，good floating stability and consistent inflation speed for the trestle bridge
airbag. |
