The construction method of the shield is the construction of the tunneling machine at the same time.
It is understood that the amount of tunneling using the shield method accounts for 45% of the total subway construction in Beijing, and a total of 17 shield machines are effective for subway construction. Although the cost of the shield machine is high, it can increase the efficiency of subway excavation by 8 to 10 times, and during the construction process, there is no need for large-scale demolition on the ground, no blocking of traffic, no noise during construction, no ground settlement, and no impact on the normal life of residents. However, large shield machine technology has high added value and complex manufacturing process. Only a few companies in Europe, America and Japan can develop and produce.

The rudder blade is an important component for controlling the course of the ship. It generates the rudder force through the connection with the rudder stock and the rudder pin, thereby changing the direction of the ship. Rudder blades are usually made of wood or steel. Most modern ships are made of steel, and in most cases they are welded into a hollow wing structure. The design and structure of the rudder blade have a direct impact on the maneuverability of the ship. For example, in order to improve the maneuverability, some ships adopt high-efficiency rudder blade structures such as flap rudder and Xilin rudder, but the production and maintenance costs of these structures are high.

Hatch cover is the main equipment in ship machinery
Cargo cover is a kind of closed equipment to ensure the watertightness of the hull and the safety of the cargo in the cabin, and it also has a certain ability to resist pressure. The degree of mechanization and automation of the opening and closing of the hatch cover is directly related to the labor intensity of the personnel, the loading and unloading production efficiency of the ship and the berthing time in the port.
