While ushering in development, it also faces many development challenges, and the difficulty of building construction increases. The construction industry pursues the quality and efficiency of construction, hoping to save construction time to the greatest extent and achieve rapid return of funds on the basis of ensuring construction quality. Therefore, high formwork support construction technology has been widely used in the construction industry, and has gradually become the most critical construction technology in my countrys construction sites. This technology pays more attention to all aspects such as construction plan and installation, which can ensure the quality of construction, improve the technical level of the construction industry, and reduce the occurrence of various safety accidents.

The bridge is situated in a valley plain which is crossed by small rivers and was designed principally with the environment in mind. The bridge length is over 356 m, and the width of the decks is 11.5 m. For the bridge works, a simple conventional falsework system was chosen with steel frames for the supports and steel rolled beams for the decks. The formwork was constructed in solid timber and plywood as multiple-use panels. The falsework was designed in order to build the two 10-span bridge decks in stages. The decks are continuous cast-in-situ prestressed concrete twin rib with spans of 30 m, 34 m and 45 m. An individual falsework system was designed, which was easy to move transversally following completion of each stage for one deck. After finishing each stage, for the second deck, the falsework was dismantled and used again in the next construction fronts. An individual arrangement for the falsework along with timber pilings was used to cross the biggest river. The formwork timber panels were used several times in the multistage bridge construction. The adopted falsework system is very simple, but it allowed the speedy construction of the two decks where there were severe time constraints.展开更多
