Introduction

Railway investment is now welcome good blowout concrete machi

   China Railway Corporation, the latest statistics show that the first half of 2014, the national railway fixed assets investment of 327.3 billion yuan, an increase of 51%. In the first half, dense started 14 projects with a total mileage of 3,712 kilometers, taking into account the investment objectives 800 billion this year, the second half of the provinces will be invested in railway construction nearly 500 billion. 
   Construction of the railway construction project is divided into several areas subgrade engineering, bridge construction, tunnel construction, rail engineering, station house engineering and electrical engineering, in addition to electrical engineering, other engineering will be used more or less concrete machinery, and bridge engineering concrete is one of the most dependent on mechanical engineering. 
   Precast concrete box girder bridge project is divided and place concrete box girder, which mainly prefabricated simple box girder. Whether it is cast or precast box girder box girder, concrete production are centralized plant mix, average 10-15 km Plains set a concrete mixing plant, the production capacity of about 100 ~ 150m3 / h, the configuration of about 15 to 20 concrete mixer truck, concrete pump sets 4-6 complete casting operations. Precast Box mainly by every 20-30 kilometers built a precast concrete beam field, on-demand production of certain specifications (including 20 m, 24 m and 32 m, with 900 tons of 32 m box girder majority) of precast concrete box girder. Mainly by manufacturing precast concrete box girder concrete mixing station, concrete trucks, concrete pump (or pump), concrete placing booms and other machinery to complete. Under unable to use prefabricated Charpy case, you must use the in-situ concrete continuous beam, steel beams. 
   Because in this round of railway construction, high-speed rail occupy a large proportion, and in order to driving safety, high-speed multi-use non-ballasted track, so there is a certain track construction in demand for concrete machinery. Investment in infrastructure for the development of the concrete industry is "double-edged sword", and "micro-stimulus" An important goal is to avoid blind expansion of business case production capacity of stimulating economic growth, after all, "four trillion" is still vivid in my mind. Railway construction, especially high-speed rail construction as "micro-stimulus" will undoubtedly be an important means to stimulate the development of concrete machinery, Chinese concrete machinery manufacturing enterprises need to think about is what kind of attitude to respond to new opportunities.
