On October 25, 2005, it was learned from relevant parties that the first batch of imported shield machine components on October 24 had been delivered to Shenyang Heavy Machinery Group Co., Ltd. by Germany. Although the parts delivered this time weighed more than 20 tons and loaded two containers, for a shield machine weighing several hundred tons, the one that arrived in Shenyang was only one of the shield machines. A small number of components.
As a special engineering machine for tunnel excavation, the manufacture of shield machines is very complicated. In particular, the modern shield tunneling machine currently used adopts a robot-like technology, integrating control, remote control, sensing, guiding, measuring, detecting, communication and other machines, electricity, liquid, sensing and information technology. Cutting, conveying soil slag, assembling segments, tunnel lining, measuring and guiding rectification, etc., is the most advanced tunnel excavation equipment in the world.
However, due to the huge consumption of the shield machine by underground excavation, the shield machine weighing several hundred tons will be scrapped if it can't be dig a few kilometers. In the construction of the subway, it is a big expense to purchase the shield machine. To this end, Shenyang City decided to use its strong equipment manufacturing strength to produce its own shield machine. In the end, this burden fell on the heavy group. According to relevant personnel of the Heavy Group, the heavy group will manufacture two shield machines for the Shenyang Metro. After completing the first one this year, another one will be built next May, many of which are imported from abroad and then assembled by the Shenyang Group.
It is understood that the heavy group began preparations for the construction of real estate shield machines in Shenyang by the beginning of this year. In August this year, it officially signed a purchase contract for the key components of two earth pressure balance shield machines with the German Wilt Group. At present, the key components of the shield machine that need to be imported from Germany have already settled in the first batch, and the parts of the shield machine that need to be manufactured by the Shenzhong Group also enter.
Production stage. It is understood that in the middle of next month, after all the key imported parts are delivered to Shenyang, the heavy group will begin to formally assemble the shield machine. At the end of next month, the first shield machine made in Shenyang and used for subway construction will be assembled and officially unveiled.
In order to start the construction of the subway as soon as possible, the key parts of the shield machine were transported to Shenyang, and the relevant departments all walked green light, which created a lot of advantages for the shield machine to sink.
condition. Moreover, due to the large size of the shield machine, almost every component weighs more than 20 tons, and some even exceeds 60 tons, and should not be stored in the open air. Since the Shenyang Bonded Warehouse does not have storage rooms and lifting equipment for storing such large-sized goods, Shenyang Customs decided to set up an special import storage room in the Shenyang Heavy Group workshop. This will not only shorten the production of shield machines. Loading and unloading time, etc., and will also save a lot of secondary lifting costs.
