The mobile mold base, also known as slip mold base (referred to as the sliding mode) or move Launching Gantry and bridge construction in emerging large equipment. The construction technology mobile moldbase has wide adaptability, turnaround times, short construction period, construction of safe, reliable, simple scene civilization, does not affect bridge traffic, high degree of automation machinery, to facilitate project management features. Mobile framework construction method as a new construction technology, more and more widely in the bridge construction has been applied, and achieved good economic returns. This paper via mobile moldbase practical application in the construction of cast-in-place box girder, research the mobile moldbase the main construction works; the mobile mold frame construction technology and construction quality control measures. In practical engineering applications, analysis of the strengths and weaknesses of the the mobile moldbase construction technology, and in accordance with the requirements of the practical application of the proposed improvements and the future direction of development. Combined the mobile moldbase system structure composed MSS35-7500 type moving die carrier by highway construction in the practical application of the the mobile moldbase system works, the major structural features and MSS35-7500 mobile mode The main technical parameters of the frame construction deflection control computational analysis. Construction technology the mobile moldbase system. Construction preparation; mobile moldbase how assembled; construction of reinforced and prestressed tendons; internal model construction; concrete construction; moldbase automatic landing gear shifting, moving forward, the construction cycle; two moldbase to the left and right in the same bridge two how to parallel many aspects of the construction and concrete box girder end cracks precautions, operation and precautions, and ranging from high beam box girder construction method to use the same set of mobile moldbase,. Combined with the actual situation of the construction, the using mobile moldbase construction quality control measures. Including the mobile moldbase assembly quality, the use of mold release agents, reinforced construction, concrete construction, and maintenance, the two-box girder concrete backplane dislocation precautions, sunroof hidden quality prevention measures, prestressed construction, formwork mobile construction observations construction in winter, the rainy season, construction and other aspects of quality control. By the mobile moldbase in construction, mobile modular rack system, the the mobile modular rack system development and suggestions for improvement.
