(Summary description)Jiangsu pipe jacking machine and shield machine are widely used in mechanical production. What is the difference between Jiangsu pipe jacking machine and shield machine? Some of the original cores of the Jiangsu pipe jacking machine are integrated inside the exit features of the tunnel boring machine, so that its size can be reduced. Its external pushing device, pushing the pipe section, promotes direct tunneling through the head, the top of the machine, so it gets its name. Unlike the tunnel boring machine used to support the tube sheet, the top of the machine that advances the cut drill bit tube section acts on the carrier. The tunnel boring machine is a complex, highly automated, and efficient equipment used to construct tunnels of various scales, sizes, geological conditions and lengths. Of course, it is also very expensive. For some tunnels with a smaller cross-sectional diameter, such as 2 meters or less, the tunnel boring machine cannot do anything. All the components are compressed into a small space, such as a screw shell, etc., without opening the display. Since the small diameter of the tunnel is usually a conduit, the difference between the two can be summarized. The so-called shield tunneling type tunnel drilling machine or machine is usually used for excavating large diameter parts, the rock geological conditions can be competent, and the top of the machine is usually used for small diameter parts of soil excavation. Because the shield machine is in front of the jacking device, we are more flexible, can carry out long-distance construction, and can pass a certain time curve radius, while the pipe jacking machine is just the opposite. Jiangsu pipe jacking machine is used in municipal engineering, and the price is much cheaper than tunnel boring machine. After many things arrived in China, the pipe jacking machine also developed into a special shape, which does not change its basic properties, that is, in the rear pipe jacking section, so it is still cheaper than the shield machine. In some cases, it can replace expensive tunnel boring machines to obtain cost advantages. Great progress has been made in tunneling and pipe jacking, including special-shaped equipment.
