In ancient times, the port was relatively backward, all goods needed manpower to carry out, whether it was to load goods on the ship, or to unload from the ship, it was inseparable from a large number of coolies, the number of coolies and whether they were strong or not, directly determined the efficiency of the port operation.

Evaluate the prosperity of a port, it can be seen from the number of coolies, the number of coolies is a hard indicator of port prosperity, more reliable than the size of the port, the port does not mean that it must be prosperous, but if the number of coolies is large, it must be a prosperous seaport, because coolies need to eat, a port can gather a large number of coolies, it is enough to show that the port is very frequent, and the coolies have enough work to do.

However, the large number of coolies, moving goods back and forth, also made the port chaotic, full of people working, and the goods were piled up in a mess, how could it not be chaotic.

The larger the port, the more serious this confusion becomes, and sometimes it can even lead to conflicts, armed clashes, and further chaos.

In ancient times, the transportation conditions were very limited, the transportation cost of carriages and horses was relatively high, and the use of ships to transport a large amount of money can be a good cost savings, so water transportation has always been a very effective mode of transportation, which is valued by all merchants.

Whether it is the starting point or the end point of water transportation, it is on the wharf, so the wharf is very important, if anyone can control the wharf, who can control a steady stream of wealth.

In many eras, in order to compete for the dock that can generate wealth, many underworld forces will fight to the death, and the dead are one after another.

In later generations, there was a small fishing village called Shanghai, because the geographical location was very suitable for the port, it was built into a very large port by the Western powers, the scale of the city continued to expand, and the number of wharves also increased again and again, and among them, many wharves were controlled by different underworld forces, so that the wharf became a tool for them to collect money.

Tanar is also a relatively important trade transit point, especially in the era when the shipbuilding industry is not very developed in Datang, the self-sustaining power of sea ships is very limited, and it must dock at a seaport like Tanar, so it is quite important.

Since it is an important port, Ang Lee naturally has to go all out to build it, and at present, improving the efficiency of loading and unloading cargo at the terminal has become the latest goal pursued by Ang Lee.

Different merchant ships are suitable for docking in the port, and the height of the deck from the shore is different, almost all of them are much higher than the dock.

When unloading and loading, it is necessary to put an inclined plank on the deck of the ship, so that the coolies can walk along the deck to the merchant ship, and then carry the goods on the merchant ship, walk down the plank with the slope, pile the goods on the dock, and then continue to carry them, and these goods piled up on the dock will be pulled away by someone leading the wagon.

This primitive unloading method lasted for almost thousands of years, and it was not until the rise of large-scale ocean trade in later generations that it gradually became container unloading, which greatly improved the efficiency of unloading.

In this era, it is difficult to carry out huge container transportation, because the containers of later generations are too large, and they need to be lifted by a very huge crane, and such a huge container, ordinary carriages cannot be transported, in short, it is all kinds of unrealistic.

However, the use of cranes to lift goods directly from merchant ships is a good way to achieve it, but mechanical cranes are only available in Datang, and the number is still relatively small, so I am afraid that it cannot be applied to Tanar for the time being.

The use of movable pulleys to reduce the tensile force can work, as long as a few more movable pulleys are used, the weight of the cargo can be reduced several times, so that a coolie can easily unload it.

The simple survey of movable pulleys is not very difficult to manufacture, and with the current conditions of Tanar seaport, it can be built.

In addition, it is necessary to build a strong crane column on the dock, and a horizontal wooden pole on it is used to install the pulley.

The whole mechanism requires a strong rope, one end of the rope is in the hands of the coolie, and the other end hangs an iron hook, the iron hook is used to hook the goods, and the coolie is responsible for controlling the rope and direction, so that the goods can fall steadily.

Some of the goods are relatively small, only one person can easily carry it, if you use such a large equipment, one by one to transport this kind of not very heavy small sack, it is too cost-effective, not economical enough.

Therefore, it is also necessary to have a square box with a proper head, the top of the box is open, and one of the four sides can be tiled down to facilitate loading and unloading.

When in use, the empty box can be hoisted onto the merchant ship, and then, using coolies to pile a large amount of goods in this large square box, after the preparation, carefully transfer the box to the dock with the goods, open a panel on the side, and the goods can be easily unloaded.

If there is a transport truck next to it, it is even more convenient, just pour the goods directly into the transport truck.

In this way, it seems that the number of transportation is more frequent, but there is less process of carrying the goods on dangerous wooden boards, which is not only labor-saving and safe, but also definitely faster than direct transportation.

Especially when encountering large goods, it is often necessary to lay a lot of formwork, more than a dozen people to carry together, in order to move the goods down steadily, if the crane system is used, it can be easily moved down, and the efficiency is improved more than a little.

Li An had already thought about this problem yesterday, so he had already drawn the drawings and immediately handed them to the subordinates behind him, and said: "This is a crane, which can make the unloading of merchant ships easier, so that local craftsmen can build it immediately, and the official must see the effect as soon as possible." ”

"Yes, Li Shilang, my subordinates understand."

The subordinates hurriedly finished the drawings and carefully handed them over to the people behind them.

The commercial terminal is barely able to maintain at present, and the only urgent improvement that Li An can think of is to improve the handling method, and as for the expansion of the scale or something, it still needs to be changed after the funds are in place.

Moreover, the commercial harbor in front of it is not too large, the potential for modification is very limited, and the shipyards and fisherman's huts on both sides make this harbor basin not destined to be the main port of the future.

The shipyard is a small facility, which can only build extremely simple small boats and medium ships, and the shipbuilding technology is very half, and there is nothing commendable, Ang Lee does not plan to change him, it is good to keep it for the time being, after all, the shipyard has a ship repair function, there are so many ships in the port, it is inevitable that there are ships that need to be repaired, and this shipyard is capable of this task.

The fisherman's hut is a major feature of the civil port, and it is also quite lively here, when the men go out to fish, the women will make salted fish at home, and the children will play happily nearby, but these children are dirty, and they look like children of poor families.

The existence of the fisherman's hut makes the whole harbor quite warm, increases the popularity of the harbor, and makes the harbor look more prosperous, so these unmanned huts cannot be moved, and it is good to put them here, anyway, the main port needs to be relocated and built in the future.

At this time, most of the fishermen went out to sea, and there were very few fishing boats left in the harbor, less than ten at a glance.

Because the fishing technology of this era is still very backward, it cannot pose a substantial threat to the fishery resources of nature, so the fishery resources are always abundant, which also ensures that fishermen can catch a sufficient amount of fish every time to feed themselves and their families.

The fishing boats have not yet returned, and as soon as the fishing boats return, the flow of people at the fishing pier will quickly increase, and the vendors who buy a lot of marine fish will quickly snap up the fish they need.

Even now, there are fewer hawkers waiting at the fishing docks, and as long as the fishing boats dock, they will run over to buy them.

The fishy smell near the fisherman's hut was too great, and Li An couldn't stand it for a while, so he hurriedly left with his subordinates and went to the barren beach next to him.

The barren beach is very large next to the commercial harbor, and there is a path that extends further into the sea, so that the sea in front of the beach becomes a terrain on both sides, and it only needs to be slightly modified to form an extremely large harbor.

In Ang Lee's eyes, this place can become the main port of commercial trade in the future, and it is also the main location for the supply of commercial ships, when this main port is built, the commercial wharf of the original port can be gradually dismantled, and the place can be ceded to shipyards and fishermen.

After all, there will be more and more ships coming and going in the future, and there will be more users who need to repair ships, and the existing shipyards will definitely be too busy, so sooner or later it will be expanded, and occupying commercial land is the most suitable.

"The place could be fenced off to create a new port, and the path that jutted out into the sea would be heightened and widened so that it could be turned into a dock where goods could be stored."

Ang Lee pointed to the nearby terrain and began to deploy the construction plan.

In order to increase the efficiency of unloading and replenishment, it is necessary to build wharves in all three directions of the new port, only the side closest to the sea, and only build a closed wall that is not too long to block the impact of the waves and protect the ships in the harbor.

"There are also these places, large water towers must be built, and the merchant ships that come and go need to be replenished with fresh water, and there will be more and more merchant ships in the future, and there will be a lot of fresh water that needs to be replenished, and this facility must be built well, so that the merchant ships that come and go cannot be delayed because they cannot supply fresh water in time."

Li Ang continued to arrange.

"Yes, Li Shilang, my subordinates understand."

Replenishment of fresh water is very important for ocean-going merchant ships, and when all ocean-going merchant ships pass through the seaports along the way, there is no shortage of fresh water, so the efficiency of replenishment is very important.

In many backward seaports, the way to replenish fresh water is very cumbersome, requiring sailors of merchant ships to transport empty buckets off merchant ships, then fill the port with fresh water, and then laboriously transport wooden barrels filled with fresh water onto merchant ships.

This back-and-forth transportation in wooden barrels is too time-consuming and tiring, and will seriously affect the speed of replenishing fresh water.

After the construction of the water tower, the efficiency of supply can be greatly increased, the water tower storage tank is built at the highest point of the water tower, the height of the bottom of the pool is higher than the deck of the merchant ship, in this case, only a thin and soft pipe is needed, the fresh water in the water tower can be introduced into the merchant ship, the speed is far more than the manpower of the carrying, and the efficiency of improvement is not a little bit.

After so many years of development in the Tang Empire, it has been able to manufacture soft pipes, especially after the development of the rubber industry, rubber pipes have been manufactured, and Li An's ships have carried a lot, which can fully meet the requirements of the harbor.

As for the source of fresh water from the water tower, it is water from nearby wells, and a crane device is used to transport large barrels of fresh water into the water tower's pool, so as to meet the supply needs of merchant ships.

Therefore, in order to maximize the replenishment efficiency, each water tower must be equipped with more than one crane mechanism in front of it to quickly input fresh water resources to the water tower to ensure the supply needs of merchant ships.

In addition, it would be even better if a few more fresh water wells were drilled near the harbor.

There is also the collection of rainwater, it will also be a very good way, in the tropical seaside, the chance of rain is still more, and the rainwater is fresh water, as long as the low-lying position to make a cement structure of the underground reservoir, then the rainwater will not be wasted, directly from the underground rain reservoir to transfer water, the effect is faster than well water.

Of course, if Datang's pumping machine is popularized here, the effect will be better, at that time, even the water tower will appear redundant, because the pumping machine can directly pump well water to the reservoir of the merchant ship, and in the leisure time, it can also pump water onto the water tower, so that at the busiest time, you can start work in two places, the pumping machine and the water tower are replenished together, the efficiency is directly doubled, and the effect is leveraged, and at that time, the crane becomes a spare tool to prevent the pump from being damaged and unable to replenish.

At the location of the wharf near the sea, more cranes should be built to meet the needs of transporting various materials, and the open space behind the crane should also be large enough, so that it is not easy to produce a chaotic feeling.

Of course, it is also imperative to set up a transport vehicle, so that the materials unloaded by the merchant ships can be transported more quickly, so as to avoid occupying the precious open space of the port and hindering the normal operation of the port.

Although it is a civilian port, the most basic defense settings are indispensable, especially since this will be the main port of Tanar in the future, and the security cannot be relaxed, and it is enough to build a few watchtowers and two powerful turrets.
