"Lao Gantou, Lao Gantou......" Niu Dali saw that there was no one around, so he gently called Jiang Laogan, who was laying bricks next to him.

Jiang Laogan didn't want to pay attention to him, but he had already called several times, so he had to stop and look over, "What's the matter?" ”

Niu Dali walked over, with a greedy face, and said mysteriously, "Brother, you said that sea dog, how will Chief Huang punish him?" ”

"Where is this what I can know, I advise you not to inquire." Jiang Laogan used a gray knife to pick up a lump of cement from the mud basin, then smoothly smeared it on the brick, and looked at it with his eyes, feeling very satisfied, and the skills he had practiced for many years were not in vain.

Because Chief Huang said yesterday that when masonry, the standard of this ash joint should generally be controlled at 10 mm, and the top and bottom should not exceed 2 mm.

I was about to put this plastered brick on it, but I found that Niu Dali, who I thought had already left, was still standing there, as if there was something unspeakable, I wanted to say but couldn't say it, and I looked constipated, so I asked, "Dali, what else do you have to do?" ”

"No, no......" Dali shook his head in distress and turned around and walked back.

Jiang Laogan behind him also shook his head and sighed, "Young man, ......"

Walking back to the corner where he was building, Niu Dali picked up the ash knife in the mud basin, this thing is good, except for the handle made like an oval eggshell, which is made of wood, the other parts are made of iron, including the brick knife that is now placed on the ground is also iron, but the standard is not much different from the ones he used before.

In fact, from ancient times to the present, in addition to the increase in the number of tools used by these plasterers, such as mortar mixers, levels, leather counting rods and so on, and other things like ash knives, brick knives, calendering trowels were available in ancient times, but most people at that time used simple wooden boards, while modern ones are made of steel plate materials, and the quality is of course the best.

The construction tools bought in a hardware store on the street in modern times are better than those in ancient times, because this is a progress in general materials, just like a refined watermelon knife is definitely a treasure knife in ancient times. Of course, there are some tools that have not changed at all, such as hanging hammers and ink fountains, which are basically unchanged from ancient times.

Niu Dali was holding the ash knife in his hand, but his mind was not on it, so he dug the cement several times in a row, either too little or too much, and when he was cutting and repairing, it was also because he was absent-minded, so he couldn't do it just right, "Alas", Niu Dali sighed, simply threw the ash knife into the mud basin, and squatted down with his head.

He was very distressed in his heart, and he had been hesitating whether to "confess" to Chief Huang, because yesterday, Chief Huang asked them to measure the length, width and thickness of the red bricks.

It's just that when he wanted to report, he found that everyone in front of him was sincere and reported the same, he hesitated, to say or not to say, when it was his turn to be the last, he thought that Chief Huang had sworn just now, and the others were also in unison, could he say it wrong.

So he had to go against his heart once, this is like the "emperor's new clothes", one infected one, to the most lu, Huangshi naturally heard the sound of "praise", in fact, this brick is not to add money can not do not miss a penny, no matter how good the standard brick error of 1-2 mm is very good, there is an error of 1 mm up and down are top.

Not to mention the whole cart of bricks in Huangshi, Huangshi was drawn out for inspection at the beginning, and the bosses have always had a set of things to do.

Therefore, Huang Shi is a rookie in the construction industry in modern society, but the natives under him do not understand this, and ignore some intentionally or unintentionally, after all, the vernier caliper is more than a millimeter when you look up, and a little less when you look down, this kind of existence is in everyone's heart.

But Niu Dali, who is squatting on the ground now, is a rigid person, otherwise he would not have dared to talk back to the second housekeeper with Jiang because of some salary matters, and he was finally put in a private prison with an excuse, so yesterday's disobedience made him angry, and the touch of the Chen Haigou incident this morning made him extremely entangled.

"Forget it, I still have to talk to the chief......" Niu Dali stood up suddenly.

……

The Huangshi that Niu Dali is looking for is on the edge of Sanwan at the moment, and he is now directing a group of people to prepare to build a floating dock, because he has explored before, only the southern section of Sanwan has better water depth conditions, like the sea ship named "Chenggong", which can get closer to the coast more without being stranded, so he is ready to use this place as a place for personnel to land and unload cargo in the future.

I remember that one of his favorite books to read was once introduced that a conventional port terminal needs to have breakwaters, various forms of wharves and trestles, as well as some mechanical unloading tools such as gantry cranes, tower cranes, bridge cranes, grabs, and conveyor belts.

It's just that this Dongluo Island is defined by Yellowstone as a military fortress and transit base, rather than as a commercial trade transshipment port, so he basically does not plan to build those mechanical unloading tools and stacking warehouses, because they are exposed to the wall, and as soon as the enemy comes, it will be easy to be wiped out by their fire.

Therefore, he was only going to build an artificial trestle, because in the past he used to use small boats to transport back and forth, so the speed of bargeing between the ship and the shore was too slow, so he said that the last time he transferred 150 people from the ship, it took more than four hours, and if there were people coming every day in the future, it would not be even more bloody.

So from that time on, he began to prepare, first searching for information on the Internet, then asking people who know how to do it, and then going to the field to investigate. Only then did he know that it was not easy to repair this, it was necessary to have professional construction equipment, and the construction period was still very long, so Huang Shi thought that it was impossible for him to invite the construction team over, so those under him had no construction experience, and it was estimated that the construction period would be longer.

And because the water level changes frequently, the dock and trestle of this fixed structure often cannot meet the requirements, so you can only go on the floating dock, which is the simplest solution. It is also introduced in that book that the British and American forces in World War II used floating docks on a large scale during the Normandy landings, and the effect was very significant.

Of course, this is still the floating dock 70 years ago, so how about the floating dock now, Huangshi immediately searched on Baidu, all kinds of network information is rich, even a variety of floating dock pictures are available, Huangshi clicked to see, now this kind of dock is basically used for yacht docking, the material is wooden, and all plastic.

No wonder they are often called yacht docks, floating docks, and the composition is mainly composed of embankments, fixed slopes, movable ladders, main channel floating docks, branch channel floating docks, positioning piles, water supply, power supply systems, ships, water and water ramps, lifting devices, etc.

For this reason, Huangshi went to the marina to take a look, in fact, it is divided into plastic pontoons, hot-dip galvanized steel structure, anti-corrosion pine surface, approach bridge and other components. The embankment part of the embankment is poured with reinforced concrete on the basis of masonry, and the steel structure hinge device is embedded at the junction of the movable ladder.

The main structure of the steel structure movable ladder is hot-rolled channel steel, the handrail is linked with square steel pipe or round steel pipe, which increases the load capacity, and the ladder surface is laid with anti-corrosion template. The movable ladder is connected with the embankment by hinge, the movable ladder and the floating wharf are in contact with the movable pulley, and the steel plate is laid in the stress area of the pulley, and the steel structure skeleton of the floating wharf is strengthened to increase the stress area.

The main floating dock and walkway are mainly composed of three parts, the first is the buoyancy part of the buoyancy tank, the second is the stressed steel structure of the link and the loaded body, and the walkway is paved with a layer of wooden skeleton and wooden floor. Then there are positioning piles around the main pier and walkway, mainly prefabricated concrete pipe piles, but also steel piles or cast-in-place piles, and even one or two wooden piles.

Its water supply and power supply system, Huangshi also took a rough look, the water supply is softly connected with PP plastic pipes, and the power supply uses marine cables and special waterproof plugs. Because these two things in Huangshi have not been used for a year and a half, he only visited them under the guidance of the staff.

A staff member saw that Huangshi was asking about this, maybe she had some connections, so she came to ask Huangshi if he had this need, and Huangshi said that his friend had a very small resort on the island, hoping to find a relatively simple, convenient, economical and practical floating dock, so he asked him to look around and learn from it.

"You guys should be expensive at this dock, right?" Huang Shi pointed to the marina at his feet, which is said to be Pontianak wood as a planking material.

"This is an aluminum alloy yacht marina, we are the first few in China to use, in addition to Beijing, Shanghai and Guangzhou, this is the first one we introduced here, this money is ......" the staff said proudly, and then she stretched out her hand to Huangshi, and made a gesture with her fingers.

Seeing the little girl's green jade fingers, Huang Shi counted them, there were 7 fingers, and his heart was staggered, this is too expensive, it is too worthless to spend so much money for a small dock.
