Luoyang nine long company shield construction machine tool development trends
$info.title
In the early s, China began to shield construction machine of the development of the material of hob also many exploration experiment, but it was no professional hob production factory, scientific research units and no enough money into experiment, so that I was in the development of hob effect insufficient ideal, only in the weak shield-driven construction of scraper to explore. In the mid ninety s, mor xikang qinling tunnel scheme using TBM railway develop extensive demonstration. Due to the sword is tunnel roadheader hob circle of the main broken rock tools, the sword of the great circle consumption, increase the construction cost and influence to the construction progress. Import knife circle expensive and delivery time long, the development of domestic hob knife circle is imperative. So the whole section founded the tunnel se disc rolling.
