The reason why the inside of the port is much calmer than the outside is because of the design of the breakwater on the outside of the port, and the function of the breakwater is to reduce the waves inside the tank, so that the ships moored in the port can stay quietly in place.

Later generations also explained the term very well, saying that the breakwater was built to block the impact of waves, enclose the harbor basin, maintain the water surface to protect the harbor from the weather, and facilitate the safe berthing and operation of ships.

Breakwaters can also play a role in preventing siltation of harbor pools and erosion of the shoreline by waves, and are an important part of artificially protected coastal ports.

Generally, it is stipulated that the allowable wave height in the port is within one meter, that is, the wave in the port cannot be higher than one meter, otherwise, it is an unsafe port.

The general breakwater is composed of one or two jetties connected to the shore or unconnected island embankments, or by the jetty and the island embankment together, and the water area covered by the breakwater often has one or several gates for ships to enter and exit.

In the general public's impression, there are only two functions of the port embankment, and the two most important ones, one is to block the intrusion of the waves, so that the ships moored in the harbor can lie quietly in the harbor pool.

Another very important role is to block the entry of sediment and ensure that the harbor can have deep enough berths.

The first function is easy to understand, once there is a storm on the sea, the wind and waves are very huge, and the ship will shake very violently, and after having a breakwater, the ships entering the port do not have to be tormented by the violent waves.

Another effect, mainly in the sandy coast and silty coast is more effective, in these two types of coast, due to the effect of waves and tides, the sediment will invade the port step by step, and then make the port draft more and more shallow, seriously affect the practical performance of the port, and with the breakwater, you can deal with this problem very effectively.

Depending on the protection task of the breakwater, their shape is also different, there are slope embankments, straight wall embankments, mixed embankments, permeable embankments, floating embankments, jet embankments, and jet embankments, in short, there are many types.

There is a big gap between the performance of different types and quality requirements of embankments, cost and maintenance, and when building, they need to be designed according to the needs, and they cannot blindly pursue the beauty of performance and shape.

The breakwater is only the outermost facility of the port, and it is also a necessary part to ensure the safety of the port, and a qualified port needs to have many components, such as breakwater, wharf, ship repair and shipbuilding facilities, navigation facilities for ships entering and leaving the port, etc., these are all buildings that the port must have, and the same can not be missing, otherwise, it is not a qualified port.

The role of the breakwater, as I have just said, and the role of the wharf, needless to say, is to dock ships, so that ships can freely load and unload goods and get on and off passengers.

In general, most of the wharves are vertical wharves, and they are also the simplest wharf methods, which are convenient for ships to dock and machinery to drive directly to the front of the wharf, so as to improve the efficiency of loading and unloading goods.

In the area where the water level gap of inland rivers is larger, slope type wharf can also be adopted, and barges are arranged in front of the ramp, and it is used as a wharf, this wharf is difficult to get close to the front of the wharf due to the loading and unloading links, and the loading and unloading efficiency is low, and the floating wharf can also be used in the river, lake and the harbor pool of natural or artificial cover in the water level difference is smaller.

Barges are connected to the shore by means of movable approach bridges, which are commonly used as passenger terminals, fish unloading terminals, ferry terminals, and other auxiliary terminals.

The structural form of the wharf has gravity type, high pile type, and sheet pile type, among them, the stability of the gravity wharf is better, the structural strength is relatively large, strong and durable, easy to repair after damage, suitable for better foundation, and the other two also have their own uses.

Not to mention the dock and repair station, this is a necessary facility for a port, the ships coming and going, it is inevitable that they will encounter damage, and with the dock and repair table, the ship can be repaired, so that the ship can be put back into use, if there is no dock and ship repair facilities, it will be more troublesome, because the ship has been broken, if it is not repaired, it will not be able to continue sailing, and not being able to sail means that it is impossible to go to the rest of the ports with ship repair facilities, so, It will only rot in the existing port.

In addition to these, the general port should also have navigation facilities, also known as lighthouses, after which ships know how to enter the port.

However, at present, the fleet led by Ang Lee entered the port of Benghazi and did not see the so-called lighthouse, after all, this is only a small fishing port, only small boats such as fishing boats, and all areas of the port can be navigated freely, and there is no need to worry about running aground and hitting the reef under the water, so there is no need to build a lighthouse.

For large ships with a deeper draft, the situation is completely different, because there are also relatively shallow places in the port, and if the ship takes the wrong route, it is very likely to hit the shallows, resulting in a more serious grounding accident.

Because of this, after seeing the fleet approaching, the Ottoman soldiers stationed in the harbor hurriedly drove small boats to meet them to prevent Ang Lee's fleet from running aground.

With small boats leading the way, the Datang fleet naturally did not run aground, and after some arduous preparations, all the ships entered the port, and soon after, the storm began to gradually strengthen, and the torrential rain gradually increased.

Fortunately, Ang Lee's fleet has entered the port, if it continues to stay in the Mediterranean, it is estimated that it will be very troublesome, if not capsizing and disintegrating, at least, it will suffer great losses, if one or two ships are sunk, Ang Lee will be distressed to death, all the personnel and equipment of this fleet are elite, and the loss of any soldier and any piece of equipment is something that Ang Lee does not want to see.

Fortunately, all the crises have passed, and as long as the fleet stays in the port of Benghazi, it can guarantee absolute safety, and no matter how big the storm is, it will definitely not overturn the ships in the port.

Due to the increasing rainfall, after docking, the soldiers took shelter from the rain in the cabin, and no one left the port and entered the town, only a few Ottoman subordinates who went ashore to be with a small army stationed here.

After feeling that the hull of the ship was completely stopped, Li An was already very tired, and Li Xiaolu under him was also covered in sweat, I don't know if he was tired, or he was steamed by warm water, in short, his little face was red and fluttering, very cute.

Li Anxin was satisfied and lay down in the pool again, and splashed water with one hand to harass Li Xiaolu, who was lying on the platform gasping, and at the same time, he also washed Li Xiaolu's body.

After slowing down for a long time, Li Xiaolu could be regarded as having some strength, she flipped into the pool, wrapped around Li An like a climbing vine, and gently bit Li An's ear with her small mouth, muttering that she didn't know what to say, probably in Spanish! Anyway, Ang Lee definitely can't understand these bird languages, in his previous life, Ang Lee's foreign language level was very poor, and he still learned English, and he couldn't even think of Spanish, and he hadn't even heard of the so-called Spanish.

"What are you talking about, baby? Is it a dialect of Gibraltar? ”

Ang Lee asked.

Li Xiaolu opened her eyes, looked at Li An, and said, "Yes, this is our Gibraltarian language, isn't it very good." ”

Li An nodded and said, "It's really good, it's like a bird in the sky, it's good to chirp and call birds." ”

This is a kind of teasing that compares Spanish to the language of birds! However, Li An felt that Li Xiaolu might not be able to understand the hidden meaning behind these words, so when he said this, he had no scruples.

"Bird language is like the language of birds, so what kind of bird does Li Shilang think our language is like?"

Li Xiaolu really couldn't understand the meaning of disparagement, and carefully consulted her.

"Well, it seems that all kinds of birds are a little bit alike, but I really can't think of what kind of bird it is."

Li An pretended to be serious and said.

In fact, I couldn't hold back my heart for a long time, and I really wanted to laugh out loud to relieve this feeling in my heart.

"Well, Li Shilang said that our language is like the language of birds, so it's good to call it bird language, bird language is very good, it sounds good! Then I'll be talking about birds every day from now on, it's good! ”

Li Xiaolu said.

Li An couldn't help laughing and said: "Usually don't say it, but you can say more when you are affectionate, although I don't understand it, but it's very beautiful, much more beautiful than speaking the Tang language." ”

"Okay, then talk more bird language when you're making out, haha!"

Li Xiaolu said obediently.

The heavy rain fell from day to night, which frustrated the wishes of the soldiers who wanted to go to the port for a while, after all, no one wanted to get drenched in the rain. Moreover, the heavy rain also made the already small port town even more deserted.

Since there was nothing to do, the soldiers had to stand by the window of the cabin and watch the heavy rain outside, which was sometimes a pastime.

However, this pastime is more of a girl's habit, just imagine a classical beauty with a peugeot appearance, sitting in front of a dresser, next to an open window, drizzling rain outside, a bamboo forest and rockeries in the courtyard, and blue plantain leaves, how wonderful and exquisite it must be! And at this moment, these boring soldiers actually began to appreciate the rain, which is really unimaginable, and it can be seen that they are really boring to the top.

Fortunately, Li Ang prepared a lot of pastime tools such as picture books and chess for the soldiers, so that everyone would not gather by the window to watch the rain.

After dark, the heavy rain had stopped, and the soldiers began to leave the ship one after another, go ashore to breathe in the fresh air, and at the same time look at the different scenery here and have some fun.

According to the living habits of later generations, after dark, the nightlife has just begun, however, this era is not the era of later generations, the nightlife is naturally not rich enough, and because there is no electric light here, the night is too dark, and the light of candles alone is not enough to create a rich nightlife.

Because the population is not very large, there are not many places to open at night in Benghazi Town, there are only a few restaurants and green buildings, and the number of guests that can be accommodated is also limited, and the Tang fleet has so many people at once, which really makes these shops make a lot of money.

However, due to the overwhelm of the store, many Tang soldiers who came to have fun have fought, especially in the only Qinglou place, hundreds of Datang soldiers gathered at once, and there are only a dozen Arab beauties in charge of picking up customers, where can I be busy, and these Datang soldiers have been holding back for many days, where can I still hold back, it would be strange not to fight, there is no big problem with fighting between myself, and I can reconcile after the fight, and beat the local pleasure man, It had a very bad impact.

This can hurt the old bustard who opened the Qinglou, those local men who were beaten away by the Tang Dynasty soldiers, all of them are frequent visitors to the Qinglou, and they are the parents who take care of the Qinglou business all the year round, this time they were actually beaten away by the Tang Dynasty soldiers, and some of them didn't even have time to wear underwear, and fled back with their bare butts.

What a shame this is, besides, it has been seen by many people, especially the old bustard and the girl in the Qinglou, in the future, will they dare to come to the Qinglou for recreation? Will you have a phobia in your heart, will you be scared out of the way all of a sudden, in short, this is not an easy thing to do, which makes the bustard very worried.

But there are many soldiers in the Tang Dynasty, many of them also carry weapons for self-defense, and the Tang Empire is even more powerful enough to swallow the whole world, where do they dare to offend the Tang Dynasty, let alone fight against the Tang soldiers in front of them, so when the Tang soldiers threw out the local men who were looking for fun, the bustard and the girl in the Qinglou didn't even dare to say a word, for fear of annoying the Tang soldiers.

However, people like to try new things, and communicating with different people will produce different pleasures, especially among this wave of Tang Dynasty soldiers, some of them are very handsome and are good young men.

These Arab girls in Qinglou usually serve the same men, and they have long lost any feeling, and the arrival of these different-looking Datang men has given them a taste of freshness, and they can finally experience the taste of Oriental men, so in addition to being frightened, they also have a trace of expectation and hope in their hearts, hoping that the Datang soldiers can be gentle, not patronizing their own pleasure, but also taking care of the feelings of others.

The fight between the Tang soldiers in the Qinglou was quickly reported and reached Li An's ears, but for such a trivial matter, Li An didn't have to ask about it personally, just leave it to his subordinates to complete.

"These guys, really monkey anxious, actually threw out the Moors who were looking for fun, and let these Moors run naked on the street, fortunately it was dark, if it was daytime, it would be a big ugly, haha!"

Ang Lee actually laughed as he spoke.
