Recently, the 2010 Dalian Excellent Mass Technology Innovation Achievements Selection Campaign jointly organized by Dalian Federation of Trade Unions, Dalian Science and Technology Commission and Dalian Workers Technical Association was announced. The 58 outstanding achievements recommended by the Dachuan Group's trade union were all selected. Wang Dong and Yang Bin were awarded the title of “Top Ten Technology Innovation Experts†in Dalian.
In 2010, the outstanding achievements in mass economic and technological innovation included famous enterprises in Dalian, including Dalian lifting, rolling stock and tile shaft. A total of 143 results were selected for the competition. The 58 technological innovation projects recommended by our group were novel. The unique perspective was recognized by the expert judges and all were selected, accounting for 41% of the total number of participants. Among them, the ship's total assembly of a Wang Dong's "PC760 series ship air compressor control circuit function increase and modification" and the shipyard assembly two Yang Bin's "research and development of electrical professional production preparation work package" two projects highlighted At the same time, it was awarded the title of “Top Ten Technology Innovation Experts†by Dalian City. So far, the Big Boat Group has been ranked among the top in the evaluation of Dalian's mass economic and technological innovation achievements for six consecutive years; it has also become one of the enterprises that have been awarded the title of “Top Ten Technology Innovation Experts†by Dalian City in the past 10 years.
1. Municipal water supply and drainage: The internal pressure of high-density polyethylene (HDPE) winding reinforced pipe can reach 12kg/cm2, which is the ideal pipe to replace the original drainage cast iron pipe and cement pipe in the city. The pipe can be used for municipal underground drainage, sewage, rainwater collection, water transmission, ventilation, etc to discharge liquid and gaseous substances into rivers or the sea. Thermal structure wall winding pipe has the advantages of lightweight, safe, reliable connection,corrosion resistance, and high ring stiffness, therefore the use of thermal structure winding pipe has great advantages.
2. Large-scale water conservancy projects: long-distance water transmission, farmland irrigation, reservoir drainage, water source pipe, irrigation pipe and hydropower station water transmission, drainage use;
3. Environmental protection engineering: deep sea sewage, sewage treatment, waste
dump sewage, detoxification pipeline. Due to the thermal structure wall winding pipe of various pipe wall structures and pipe, inspection well, pipe fitting, and its reliable connection performance, the pipe can be used for advanced shallow drainage systems.
4. Petroleum industry: oil, gas pipeline.
5. Coal industry: coal transport, ventilation systems.
6. Chemical engineering: chemical containers, especially corrosive fluid delivery
pipelines.
7. Electric power engineering: circulating water pipeline.
8. Road engineering: crossing roads and railways have a large traffic load of water
culverts and crosswalks; Used as railway and highway road seepage, drainage pipe; The method of "liner in pipe" is becoming more and more important for repairing damaged pipes.
9. The laying of pipes in a corrosive environment.
10. Agricultural engineering: farmland, orchard, tea garden and forest belt irrigation, and so on;
11. Large airport port, wharf engineering: large airport port, wharf engineering drainage, sewage pipe, etc.
12. Construction engineering: building stormwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.
Communication tube: railway, highway communications, communication cables, optical cable protection pipe.
14. Water storage system: used to intercept the slow water storage system.
15. Special application: thermal winding wall winding pipe can also be used for special
purposes such as ventilation, passage, desert, swamp, lake area with fluid transport, etc.
