IV, Conclusion 1. Hiroshige grate production by 93 years to the present normal operation of the installation test, indicating good quality trial grate. 298 production grate on Hiroshige and other accessories , has been successfully installed applications, 99 years and expand production, indicating that the re-casting and forging broad Branch has produced large set of grate waste incinerator capacity. 3. production grate with the manufacturing process, for similar material, size,[link widoczny dla zalogowanych], shape and position requires accurate products, have some reference. l1 continued on page 3.3 on other parts of the design cutter design is confirmed, will proceed with the other parts of the design. First of all, should be designed to discharge ballast equipment. discharge ballast equipment should be designed to ensure that footage of the boring machine to the maximum amount of time the smooth discharge of ballast. If the pressure to maintain type boring machine, its speed should be variable speed discharge ballast should be interlocked with the driving speed, driving, and a ballast to ensure balanced, to ensure soil tank pressure constant. Secondly, the need to install temporary support segments or objects should be designed and installed devices, the lifting force should be the most important support material segment or 5 times, rotate the force should be supported in the segment or stroke care when things can spin torque, speed should ensure that its peripheral speed of 15-20 m / min range, the best should be variable speed, rotation angle for the segment should be installed around the 200 degrees within the temporary support installation angle range of objects should be designed according to needs. In addition,[link widoczny dla zalogowanych], should be designed to support the segment or transport material from the back of the tub to the installer at the crane, crane's lifting capacity by tube film or support materials and the need to transport the maximum weight the distance of the design. 4. Conclusion At present, TBM is still in the design of more backwardness, China's most boring machine designed to use less than ideal results. And to adapt to the complexity of both hard and soft rock strata and the shield type tunneling machine to keep the pressure shield machine, so far,[link widoczny dla zalogowanych], China seems not to design and manufacture of products. can be said that the wide heavy Technology 2 / 20 @) tunneling machine design and manufacturing is at a standstill. At present, the amount of required excavation of the tunnel is growing,[link widoczny dla zalogowanych], growing demand for boring machine. Recently, the Shanghai Cooperation with foreign companies, foreign key part of the design and manufacture of domestic non-critical part of the design and manufacturing methods to develop to maintain the pressure for soft soil shield machine, and achieved a more successful experience. And this is indeed is an effective way to develop new products. Because the design of the boring machine, a large number of calculations are empirical basis, the main consideration when designing the machine must be able to solve practical engineering problems, so the design of driving machines must have considerable experience in engineering. Canton Enterprise Group Co., Ltd. as a large-scale enterprises in Guangdong Province, Guangzhou Metro Line in the installation and removal of shield machine, and participated in the test section of the Guangzhou Metro Line maintenance and installation of shield machine,[link widoczny dla zalogowanych], the accumulation of a certain The shield machine manufacturing experience. In the future, we will actively participate in the construction of subway construction, and actively digesting the advanced experience of foreign countries, and increase research efforts to produce their own boring machine.
