Improvement And Application In The Engineering Of The Local Structure Of MSS

With the rapid development of China’s highways and high-speed railway construction, the construction process of continuous box girder bridge movable formwork had to extensive selection, especially in bridge construction across rivers, roads, ravines and other natural moat complex terrain of its advantages have been fully exploited. By comparison with other concrete bridge construction method, easy to find movable formwork construction method has a short construction period, for a wide range of small construction affect traffic, process procedures, linear and easy to control, no basis for processing, construction and high security Features. Has become a multi-span continuous prestressed concrete box girder construction equipment preferred.Firstly, to build a bridge for different methods in recent years, domestic and international development status and historical background of moving mold are introduced, described the recent emphasis on moving mold to develop in our country, and to use this construction method to build a variety of road rail and bridge. Run on different types of common principles and process engineering are introduced movable formwork.Secondly, for the uplink mobile formwork construction paper in Wenzhou, Zhejiang Gate Bridge project for the study, by collecting and collating a lot of movable scaffolding during construction related materials, this project runs upward mobile mold build three-dimensional model of the mold and the basic structure of the whole installation process in detail. For the downstream movable formwork combined in Wenzhou, Zhejiang Gate Bridge built in the first phase of self-propelled hydraulic MSS50ZX-1900 mobile mold new innovations include the use of efficient construction workers to bring their own bracket electric hydraulic control and quality, but also has good economic; not only solve the construction lifting equipment can not be reached, the device can not be unlucky problems and contributed greatly to the development of mobile technology formwork.Again, the process of using movable scaffolding supporting the orbit increases innovation elaborate gantry cranes, gantry increase the orbit, so moving mold in use not only eliminates the lifting costs, and shorten the construction period; processing under the process remains unchanged, the productivity has greatly improved.
