The development of Tuvalu is not talked about for the time being, time and space go back to Yunmengze in another world, and the spring of the third year of the Kaiyuan Dynasty in China.

In order to completely bring the Yunmengze area, which has become the land of fish and rice, into the control of Huaxia Kingdom.

At the same time, it is also to make it more convenient to develop it to accommodate the common people who come from all over the world.

The Ministry of State-owned Assets Supervision and Administration (SASAC) has announced a new urban network construction plan through Huaxia City's online platform.

In addition to the Huaxia City that has been completed, the Huaxia Kingdom is preparing to build another city in Yiling and Jingmen, and the three cities will be connected by roads.

The road between the three cities, together with the two waterways of the Yangtze River and the Han River, can enclose the entire Yunmengze area.

The three cities are at each other's horns, forming an approximate equilateral triangle.

The three cities at the apex of the equilateral triangle watch over each other and support each other.

Convenient water and land transportation can allow the people living in the three cities to quickly reach any place in Yunmengze to achieve full use of human resources.

Under the visual impact of Huaxia City's abundant grain reserves, no one worries that this huge construction plan launched by the Ministry of State-owned Assets Supervision and Administration is an impossible task.

The Changbanpo area outside Dangyang City has almost been bulldozed, and the direct railway to Jingzhou has divided the Yunmengze area into two.

To the east of the railway, there is a circular fertile land densely packed in a water net, in which schools of fish and shrimp and river crabs are rampant.

Using modern planting and breeding technology, eliminating the use of a large number of drugs that are harmful to the human body and may have adverse effects on the environment, Huaxia has built this water network into a large-scale ecological aquaculture base.

To the west of the railway is a fertile land.

The Ministry of State-owned Assets Supervision and Administration opened the way with grain, took advantage of the abundant cheap labor force in Huaxia City, and adopted a method similar to that of Dangyang City, and also built a direct railway to Huaxia City in Jingzhou on the hill outside Yiling City.

Some of the soil and rocks mined using modern machinery and equipment were used to raise the topography of Yunmengze, and the other part was of course transferred to the real world of Tuvalu by Wei Minsheng and Long Hao through shared space, and used as materials for them to build a city in the sea.

After the huge stones have been removed, the small stones have been manually disposed of, and there is no danger.

And those hard granite mountains are occupied by quarries large and small.

Hard granite is processed into sidewalks, floor tiles and curbstones, which are in high demand in urban construction.

These stubborn stones, which were worthless in the past, can be exchanged for a large amount of food, wine and wealth from Huaxia City after being cut and polished, which is something that people in the other world have never thought of.

In addition, in order to shorten the water transportation distance from Yiling City to Jingzhou Huaxia City and bypass some complex waterways, the Ministry of State-owned Assets Supervision and Administration excavated an artificial canal with a depth of 20 meters and a width of 150 meters next to the railway.

Thanks to real-world support, a large number of used excavators, loaders, bulldozers and other construction machinery were sent to the construction site of this artificial canal.

All of a sudden, the entire construction site has become a high-profile vocational and technical school with a scale comparable to Lanxiang.

The supporting construction machinery maintenance plant has also been established, with the support of the technical information provided by the real world, to replace parts as a breakthrough, and gradually improve their ability to repair these large construction machinery.

Anyway, the guiding ideology of the Ministry of State-owned Assets Supervision and Administration is: replace what can be replaced, and dismantle what cannot be replaced.

No matter what method you use, as long as you can use the information in your hands to disassemble all the parts that Huaxia itself cannot produce and manufacture, it is a kind of ability and a kind of progress.

These dismantled parts, after the basic performance test, can still be used parts are classified and stored for the maintenance and replacement of other similar machinery and equipment in the later stage.

With the help of computer systems, Huaxia Guo redefined the naming convention of mechanical parts and components, and classified them according to their functions in mechanical equipment.

For example, a gear, its basic role is for transmission, so it belongs to the transmission component.

The name of the gear is named according to its basic parameters, such as C050202mm19, and the first letter indicates that this is a gear.

Then three sets of two-digit numbers are used to represent the diameter, thickness and bore diameter of the bottom shaft of the gear, and mm indicates that the first three sets of numbers use millimeters.

And the last set of numbers indicates the number of teeth of that gear.

Under such a naming convention, as long as you pick up any damaged gear and enter its diameter, thickness, bottom shaft bore diameter and number of teeth on the computer system interface as required, you can know whether there are the same type of gears that can be used for repair and replacement in the mechanical parts warehouse of Huaxia Kingdom.

For those parts that have completely lost their function and cannot be repaired under existing conditions, they can only be completely disassembled into basic materials and sent to the scrap steel disposal site and garbage disposal site in Huaxia Villa for sorting and processing.

The various lubricants dismantled from those machines are also collected and stored in a centralized manner.

After a large amount of used engine oil is divided into plastic bottles, it is sent to the machine construction site to lubricate the mechanical friction moving parts and realize the reuse of waste.

Due to the super lubricating properties of these used engine oils, a special profession has even emerged in Huaxia City.

They carry waste engine oil and specialize in treating all kinds of dissatisfaction with home door locks.

After putting some oil on the door lock, the experience is very different, and the residents only pay five cents and one piece.

Of course, these alternative professions have their legitimacy as long as they exist.

If you are willing to do so, you will not harm the interests of specific groups of people, and Huaxia will not care about such a thing.

Wei Minsheng believes that in the process of a large number of dismantling work, the mechanical level of these skilled workers will inevitably be greatly improved, and these experiences cannot be cultivated through boring teaching methods in the classroom.

Anyway, these second-hand machinery and equipment are not worth much money, and the right should be given to them to practice, and there will always be a time when real mechanical maintenance talents can be cultivated among these skilled workers.

In addition to sorting and smelting scrap metal, the scrap steel disposal yard in Huaxia Villa is also responsible for forging a large number of hand tools used by stonemasons, as well as some simple agricultural tools.

Due to the current stage of Huaxia, there is no technology and ability to detect and control the content of trace elements in the metal in the forging process.

Therefore, for those materials with special properties, the same parts can only be pooled, melted together in an intermediate frequency furnace and stored.

When a certain number of these different types of metal pieces are reached, they are sent to the real world for overall melting, and then their composition is tested to determine how some of the trace elements can be added or removed to produce special steel.

In fact, the difference between "strip steel" and regular steel is nothing more than that there is no analysis and laboratory testing of the composition of the steel, and there is no quality control system such as temperature.

If the composition of these "strip steels" is tested in a regular factory, supplemented by modern smelting methods, efficient recycling and reuse can be realized.
