Research And Practice On The Road And Bridge Construction Management Of Precast Beams

With China's rapid economic growth, modernization and the constant increase in road construction has entered a golden era, a huge amount of investment each year.Highway bridge construction projects will become an important part, it will also be exposed to more and more large-scale road building prefabricated field, but behind China's road and bridge construction enterprises management, extensive management is relatively common, in quality control, cost control,progress control and the effect of poor safety management, the project's operational efficiency is not satisfactory, and does not correspond to the development of the times.Especially in China's accession to WTO, the construction of large foreign companies to enter China Road market, the impact of domestic companies is not small, a greater competitive pressures; the other hand, China's road and bridge construction companies become bigger and stronger, it needs to be based on domestic, tothe world, participate in world engineering market competition, enterprises need to manage innovation, access to core strengths, enhance their competitiveness.In this paper, Tianjin, the northern section of the promenade the second phase the actual situation of Highway Engineering Project Management Theory in its factory in precast beam study the application of precast beam highway planning and construction field for the main narrative, covering the field of prefabricated buildingFrom site selection, site layout, site pre-construction to precast beams and operational framework to summarize all aspects of technology, proposed highway contracting management experience.This article summarizes the process in the construction of several new techniques and new technology:"U"type rubber to prevent the leakage of plasma technology, the implementation of the template removal order system, bar the application of positioning the mold and fixtures, sprinkler pipes and fixtures of the conservation application.Thr-ough this field of road construction of precast beams and precast girder beams of different types of transport aircraft and the construction of prefabricated field were compared, as a different type of prefabricated building construction management field as a reference.Experience and technology described in this paper can be applied to similar field Road and Bridge Construction of prefabricated construction, even in the field of construction of the railway construction beam is also a valuable reference.
