The little girl has been on the yacht dock for so long, and everyone she comes into contact with is either rich or expensive, and her ability to observe words and emotions is naturally first-class, she saw Huang Shi's brows tightened, so she said with a smile, "Actually, Mr. Huang, your dock can be used in other more popular ways, such as ......"
Her introduction really made Huangshi very interested, "You are talking about a combined marina?" ”
"Yes, this kind of dock has a non-slip design on the surface, and you can also lay wooden planks according to your needs, which is the most economical way to build a dock while ensuring quality and safety."
"However, Mr. Huang, this kind of combined module is linked by pontoons, and it can only be built into small and medium-sized marinas, while large ones such as freighter terminals need other materials with higher bearing capacity to build."
Then the little girl named Li Mo introduced to Huangshi that the main body of the floating dock was a pontoon. The buoyancy and carrying capacity of the pontoons are sufficient for small and medium-sized marinas, and each individual unit can carry a weight of 360 kg.
If the single-layer pontoon can not be satisfied, it can also be added as a double-layer pontoon dock, and the two sides are fixed with an iron frame, which greatly increases the buoyancy of the marina and ensures stability and safety.
The floating dock with the pontoon as the main body can also be designed with different shapes according to the size of the hull. Planks can also be laid on the walkway as needed, which will extend the life of the pier to a certain extent.
Because the price is really cheap, especially if it is a self-construction, so Huangshi immediately asked Li Mo for the factory site, sure enough, she has her own channels, and she found a phone number on her mobile phone, saying that she asked Boss Huang to talk about it.
The sedan chair is lifted, and of course Huangshi understands the bends and bends in it, so after he remembered the phone number, he used his mobile phone to dial the other party's manufacturer, and found the sales manager and told him directly that he was introduced by Li Mo, and he wanted to buy this floating equipment, hoping to give a discount on Miss Li's face, so that Li Mo on the side narrowed his eyes into the moon when he heard it.
……
Although this equipment manufacturer is far away in Guangdong, but after the opening of the Xiamen-Shenzhen high-speed railway, Huangshi only took four hours to rush there, in the factory he saw all kinds of pontoons, there are "three-body pontoons", "large pontoons", "50cm high small pontoons", "wave small pontoons", "plane small pontoons", "double-body pontoons" and so on, a dazzling variety of patterns.
After several trade-offs, Huangshi picked a "three-body pontoon" with the largest area, because although the length and width of the "large pontoon" are 66 cm, the thickness is only 40 cm thick as the "three-body pontoon", and the "three-body pontoon" is 1.5 meters long, and then picked some hardware accessories such as bollards and ladders, and then rented a few container vans to pull them back.
Because the three bays of Dongluo Island are a natural haven, there is a section of reef beams at the southeast end around this harbor, and the beams of these two sections have played the role of a breakwater, and the power of the waves is much smaller when the waves swell into the bay, otherwise Huangshi has to find a way to build a breakwater by himself.
After returning to Dongluo Island, Huangshi put all the pontoons on the beach, divided the hundreds into groups of ten, and then linked them together through earrings to form a plane unit, and then put the short connecting rod into the hole in the plane at a 45-degree angle, and then installed it with a torque wrench, a special tool for installing the pontoon.
Because most of the people on the island had their own jobs, the installers at the floating docks had to be drawn from the basic labor camps run by Wen Dehe, so Yellowstone selected a group of younger, good swimmers.
These people are generally relatively thin, and some of them have not recovered from their injuries before, and after the injuries are healed, the militia organization is already full again, so they can only do trivial things in the labor camp, so as soon as Huangshi announced this time, almost everyone enthusiastically signed up.
Because the wrench is not difficult to use, and the installation of this pontoon unit is not complicated, so after Huang Shi taught it once, they all expressed their understanding, among them, Huang Shi ordered a young man named He Yan to temporarily manage it, and then let them lead the tools to install separately.
Huang Shi himself had to install the steel structure hinge device of the movable ladder, which was made by pouring two one-meter-deep holes after he used the crusher of "Zhenyu Weilante" to smash the reef on the pier a few days ago, and then buried two solid steel columns in it, and then poured it with reinforced concrete.
It's been a few days, the reinforced concrete has dried thoroughly, and the two pillars are really rooted, and Huangshi is very satisfied, because there are two rollers under the movable ladder, so he is not afraid that its activity will tear the pillar.
When he was halfway done, He Yang ran over and reported, "Report chief, our work has been completed, and I have personally checked it, there is no quality problem, please instruct." ”
After Huang Shi returned the salute, he thought to himself, this young man is articulate and a good seedling, and he can try to cultivate it in the future, "It's good, He Yan, you let them rest for a while, and then arrange the following things when I am ready." ”
……
It didn't take long for Yellowstone to set up the link, walk from the reef to the beach, distribute life jackets and whistles to each of them, and then let them do some warm-up work on the beach before pushing the rows of pontoons that had been installed into the sea.
Although each pontoon weighs only 18 kilograms, ten of them add up to a weight that can be picked up and thrown into the shallow sea, and then they have to be connected one by one with short connections.
Because the units were soaked in the sea, and they were swaying up and down by the waves, it was difficult to put the bolts connecting the two units in place. This combination is much more difficult than on the beach, which makes Yellowstone think about it at first, and then think of stabilizing it by anchoring first.
"Ho Hao, you let them install this on the edge of each unit." Yellowstone took out a lot of bollards at once.
After they installed it, they then took out dozens of anchors, and let them tie it to the bollard and then throw it into the sea, which did have an effect, and the ups and downs were much smaller all of a sudden, so they stumbled and stumbled for more than two hours, and finally spliced the 15-meter-wide and 75-meter-long trestle bridge.
Everyone wore life jackets in the sea to push this floating trestle, slowly drifting in the direction of the pier, and finally in the evening, the floating pier was officially completed, in addition to the bollards of every few units, there was a whole row of guardrails, after the installation of the movable ladder in Yellowstone, the trestle was officially completed.
……
"Chief, this is really a flat walk." Chen Youxin walked on the newly built trestle bridge, and he almost didn't feel any shaking, and Zhang Chen on the side was also amazed.
Since the last time I trained Chen Youxin, it was rare to hear the beautiful words from his mouth again, and now I am very happy to hear him talk about Huangshi, and I am also humble, "This is mainly because the current wind and waves are not big, so it can be so stable, otherwise it will be shaky." ”
Speaking of which, Huangshi remembered that if there was a typhoon, this thing would probably have to find a way to put it away, otherwise the loss would be great. "Mr. Chen, there should be no typhoon after this time."
"Chief, I haven't heard of it in the past few years." Chen Youxin thought about it and replied.
"Okay." Huangshi thinks that this matter can be free to check the historical data, it is better to be cautious, especially now the camp is basically tents, if there is a sudden typhoon, there is no place to hide, but it is also strange, it has been here for two months, why is there no typhoon.
At this time, because the camp was already off work, many people rushed to hear the news, and heard that the newly built wharf trestle had been completed, and they all ran over to see something new, but they saw that Huang Shi and Chen Youxin were on the bridge, and they all stopped, and they were just probing their brains on the wharf.
Huang Shi was a little amused when he saw it, so he said to the two, "Okay, let's go up first, we are here, and they don't dare to come down." ”
Sure enough, after they left, those people swarmed onto the bridge, everyone stomped on the bridge curiously, touched the railing, and a few children wanted to run outside the railing to play in the water, and the women who followed closely behind them quickly grabbed them, reprimanded them a few words, and then stood aside honestly and watched.
"Chief, what's that?" There is a round platform on the edge of the pier, which is the place where the checkpoint is ready to be built, and they are standing on it now, Zhang Chen asked, pointing in the direction of the trestle.
Huang Shi looked in the direction he pointed, and it turned out that the trestle was now in a T-shape, and its horizontal edge was where the ship was connected to the shore, and now there were many cone-shaped transparent objects like jellyfish tied to it.
"Oh, that's Pi's seawater purifier, I used it for testing." Huangshi has been buying this thing for a long time, and has never found a chance to use it.
"Seawater purifiers?" Chen Youxin: Because they have been with Huangshi for a long time, they know the way Huangshi speaks, and they automatically have to filter out the "youth pie", and the word Zhilu Dao is equivalent to the "Li family" and "Zhang family" in the lower realm, which is just a name.
"Yes, in fact, the principle of this device is relatively simple, that is, with the help of an inflatable bag placed at the bottom, the conical container floats on the sea, and the sunlight passes through the transparent container, so that the seawater inside evaporates, and the water vapor rises to the dome of the container and condenses, and small water droplets flow along the inner wall of the container into the annular water storage tank below."
