From confirming the change of the barge, Li Qinjun conceived the transportation form of the tow barge fleet, which led to the old shipyard's temporary emergency transformation of the main tugboat.

At the same time, auxiliary power is more important in a fleet of tugboats that takes care of three or five or even more barges. The fleet slows down and brakes, gathers in and out of ports, turns, and even reduces the pressure of tugboats during over-rains. Only by coping with these situations can this form of transportation be used more widely.

The work of cleaning up the mess is not only about cleaning up and saving the mess left by previous generations, but also about sorting out previous work, starting the subsequent work arrangements, etc.

Li Qinjun did not completely deny Sun Shanming's actions, and even retained the acceptance of most things, such as general ships, assembly line processing, and those who have the ability to improve, so he organized people to make improvements. If he did not think he had the ability, he would simply adapt. After adjustment, he basically remained the same.

General Ship and Li Qin all designed two and three models based on the modified barge as a model. One has made many improvements to the hull structure layout, mainly to expand and make corresponding adjustments and adaptations, increase the installed power, etc., to design a power barge.

According to the design, the power barge will be more stable and reliable than the modified ones, and the power will be stronger. It can drive evenly and slowly in ordinary waterways and cargo. Basically, except for the Yangtze River channel in the Three Gorges area, it can basically sail normally. You can sail by yourself, of course you can also be towed by a tugboat.

The other model is shorter on the basis of the model, which is basically only about half the size of the power barge, with a tonnage of more than 200 tons. It is divided into two models with auxiliary power or not. If it has auxiliary power, it is equipped with a horsepower engine similar to the model ship. The effect is similar. It is mainly intended to form a long tow barge fleet.

The powerless model has a size and internal layout that is basically the same as the former, but it does not have power, and the appearance is more square like a coffin. There are devices for hard connection with other hulls on the outside. The hard connection is made of steel and wooden hulls and other hulls on the other hulls, while the tow is made of soft connections with cables.

These ships can be spliced ​​together to form a huge fleet, which is pushed by tugboats. Because they are spliced, retaining the power system does not have much practical effect and may even affect their use. The fleet can carry out large-scale shipping in lake areas, waterways with gentle water flow, and downstream conditions.

This model is a barge that is exactly the same as the definition. In addition to forming a fleet, it can also allow a powerful ship with rich power to tow one or two against the current and travel on a relatively gentle route, so that the reverse current can basically form a closed loop.

In addition to these barges built in the 300-ton shipyard, Li Qinjun's 100-ton construction factory also designed and built several barge models within 100-ton. Some were towed after the tugboat to load additional coal-fired fuel oil. After all, there are relatively few power ships in China, especially some branch routes at the rear, and there are basically no fixed places to supply these things.

Of course, there are also two types used for loading cargo, mainly fifty tons and hundreds of tons. They use iron and iron shells, which are faster to build and have lower costs. As these are put into production one after another, the shipyard has also become a main and minor factory under the leadership of Li Qinjun.

Whether it is powered or powered, the appearance is relatively square. Li Qinjun adopted Sun Shanming's design considerations and used a relatively straight hull to speed up construction speed, reduce construction costs, difficulty, etc. Therefore, many shipboard plates in the 300-ton shipyard were processed, and some of them were common in different ship types.

However, if it is necessary, Li Qinjun will still retain the place where it is round and streamlined, but he will try to use relatively uniform arcs. Usually, the slower the driving speed required for use scenarios, the more straighter it is, the more rounder it is than the powerless one.

The choice to build barges on a large scale was also due to the actual situation of the Lin family's layout. Although the Lin family had extremely shortage of transportation capacity in the Three Gorges section, the situation on the downstream Yangtze River channel was not optimistic.

The journey in the Three Gorges area is relatively short. Even if the journey into Sichuan and Chongqing is only a few hundred kilometers, the middle and lower reaches are nearly 2,000 kilometers. Once the ships entering Sichuan and Chongqing are solved, the insufficient capacity of this journey will appear again. Finally, after considering economic, time and other considerations, barges will be used to alleviate the capacity problem of this route.

Tow the barge fleet with tugboats and other means to the Yichang area, then unload and replace the ship, or use the tugboat to directly drag a single barge, and enter Sichuan through the turbulent waterway of the Three Gorges. When leaving Sichuan, the barge with power barges or barges with auxiliary power can go downstream by itself, or even sail all the way to the estuary of the Yangtze River.

The tugboat can push a large number of unpowered barge fleets, transport a large amount of cargo along the river at one time. When it is rejected without power, you can find a ship with abundant power and drag a few cargo back, thus forming a closed loop, allowing the entire transportation system to run back and forth.

However, all of this is still in the design or in its infancy. Even the old ship has just been modified. After a simple test, Lin Mo was hit by the first long-distance trial transportation.

According to Lin Wenqing, the difficulty of changing a ship is not too high. It is just cutting and removing the excess, and then welding accordingly. The transformation is only possible. There are quite a few eight ships, but eight ships were built, among which the corresponding new equipment such as gas cutting and welding have been used, so the progress is not slow.

After asking about other shipbuilding situations in detail, the progress of building a new ship was actually not slow, because many great people were arranged to help. After the first ship was renovated, the design of the new ship was started. After the ship was modified, many new ships had already been built on the platform.

Because Li Qinjun was only temporarily transferred to organize the mess, his original factory work was not put down, and the development was not slow during this period. Although the construction time of these barges was here, many other ship types were created during this period.

For example, motorboats of several tons or more than ten tons can be used for inspection, measurement and even assist in cleaning the waterway. Through channels, the Lin family has commissioned a national government's waterway cleaning authorization, which can legitimately clean up the waterways they want to improve.

However, the Lin family has not done much at the moment, mainly to explode reefs and silt blockages. The upper reaches of the Yangtze River are like the Three Gorges and tributary channels. Due to the rapid flow and no one is maintaining them, the navigation conditions in many places are very poor, and the ships may be destroyed at any time. In order to avoid such a big mistake, the Lin family has no choice but to do it by themselves. Now they want to rely on the government or local forces, which is simply a daydream.

In this regard, Lin Mo gave his family some advice, and could design or even build some special ships for cleaning the waterway such as sand extraction, digging, and hoisting stones in advance. If the Lin family's layout is smooth and the transportation volume will become larger and larger in the future, such casual operations will definitely not solve the problem.

Others include small and medium-sized professional ferries, and medium- and short-range passenger ships, all of which are dozens of tons. The future factories of the Lin family will definitely not be crowded in the urban area or even around, but they are likely to be built along the convenient water transportation location. Therefore, it is almost impossible to avoid the ships for factory employees to cross the river and return home. There is no way. The foundation in all aspects of the country is very thin, and you have to consider and solve many things yourself.

In this regard, Lin Mo also gave suggestions, such as ferries, which can be changed from a simple ferryman to a type that can quickly get on and off the transportation vehicle. This way, it can ferry transportation vehicles and even goods cross the river, and the application scope will be wider. Lin Mo even gave a few sketches.

In this era, it is unrealistic to engage in crossing rivers and crossing rivers. In his imagination, factories must not be too gathered. However, the Lin family invested in the construction of factories and was preparing to conduct industrial chain forms of division of labor and cooperation, which inevitably led to various raw materials, parts, etc. being transferred between factories. If they encountered crossing the river during the transfer, this type of ship could play a big role.

As for the passenger ship, Lin Mo imitated the passenger ship changed by the Li family and talked about the internal layout and safety measures. Anyway, it is a short-distance ship with seats and beds. There is no need to make a fancy cabin form. For workers, quick and convenient is real.

After asking about the situation at the shipyard in detail and giving some suggestions, Lin Mo learned about other industries where the Lin family was involved. In fact, there was not much to say. There were mixed profits and losses, some made big profits, some lost to grandma's family, and some were half-dead, even income or break even, or barely profitable. There were all kinds of situations, and it was no wonder that many outsiders used these as jokes.

The best-running factory is also the factory that produces various types of rubber products, but as Lin Mo guessed, there are many competitors. However, the Lin family has also opened up production lines or factories for many new products. Although the profit margin has dropped, the profit is also huge.

The main reason is that the current price of rubber is too low. I originally wanted to raise its price, but the price just rose a little. The rubber forest that had been abandoned or even abandoned before was immediately re-tied, quickly filling the gap, and suppressing the price back. Overall, it did not rise much.

The demand for rubber soared during World War I and the rubber heat caused by the soaring rubber price led to the planting of a large number of rubber trees in Nanyang. After the war, due to the rapid development of industries such as automobiles and other industries with huge demand for rubber, the rubber planting industry continued to grow and grow, and the planting volume increased year by year.

However, after the Great Depression in the United States, the global economy was half dead, and the demand for rubber plummeted, and the rubber price fell directly below the floor price. There are many plantations, and the amount of money to be paid for when harvesting, so it simply abandoned the cutting or even abandoned the waste.

Rubber trees are perennial crops. They have high yield periods, such as growth periods, etc., and the different outputs, quality, etc. of rubber trees in different regions, as well as the cost of labor, transportation, etc., many followers' plantations are not as expensive as others. The cost is greater than the selling price, so they can only be abandoned, abandoned, or even cut down to reduce losses.

However, most of those who have entered the age of gum-producing trees will not cut them. They can continue to survive and grow without cutting them even if they are abandoned. Once the price suddenly rises, right? In fact, the cost of sunk is too high, and few people can accept the actual cut of the flesh and leave the market, so these potential production capacity has been waiting and watching, and the price will immediately block the gap.

Of course, Lin Mo's previous thoughts seriously underestimated the supply capacity of the rubber industry, overestimated the ability of the Lin family, or overestimated the consumption power of the domestic market at this stage.
