Chapter 827: Chapter 564: Volunteer Labor
For the customs, it doesn’t matter where the seized smuggled excavator is parked, as long as it doesn’t get lost. It doesn’t matter to them whether Han Yu uses it or not, even if it gets damaged, as it’s a second-hand item anyway.
In short, with the proposal to park the excavator at the Reserve Camp, Director Zeng readily agreed.
While Han Yu was thinking about where to find a flatbed truck to transport it, "Brother Hao," who had been closely following the matter, took the initiative to arrange for a vehicle to bring it back.
He knew Xiao Yu wanted to learn how to operate the excavator and arranged for the company’s experienced driver to teach him.
While the master taught Xiao Yu to operate the excavator, he also conducted a detailed inspection, confirming that although it was second-hand, it was very well-maintained. The engine and hydraulic system were both original and hadn’t undergone major repairs. If properly maintained, it could be used for another ten years without issues.
"Brother Hao" beca more interested and repeatedly emphasizing on the phone that "good water doesn’t flow outside the paddy field," fully entrusting Han Yu to "take care" of the excavator and insisted on acquiring it once customs handles the case.
Han Yu couldn’t attend to these matters right now, nor did he have ti to learn how to operate the excavator with Xiao Yu, having already spent two days at the Changyu Shipbuilding Factory discussing with Boss Wang, Master Yang from Boss Wang’s Shipyard, Master Gu from the Developnt Zone Water Plant, and his brother-in-law Zhang Jiangkun, along with other engineering and technical personnel, how to build an ergency water supply floating water plant on a 1200-ton inland river cargo ship that was nearly dismantled.
Water intake and pressurization weren’t issues; the key was the water processing technology.
In fact, water processing is essentially water purification. Technically, there are no difficulties; current water purification technologies are well-developed.
The waterworks onshore, the desalination and purification equipnt on seagoing vessels, the Guzhou waterworks across the river... all these technologies can be referenced.
The key issue is that the 1200-ton inland river cargo ship has too limited space, while the designed daily water purification capacity for the waterworks ship serving two Reserve Camps must not be less than 100 tons, as the water supply might be needed for more than just the 300 officers and soldiers of the two camps once modified and put into use.
After two days of repeated demonstrations, they finally ca up with a plan.
The total investnt is 200,000. Han Yu, still not confident, called friends at the Yangtze River Water Resources Committee Water Station, asking them to help contact experts at the Yangtze River Water Resources Commission Design Institute and then faxed the design drawings to them for advisent.
The Yangtze River Water Resources Commission Design Institute is very professional in this area; it designed the large waterworks ship that Hanwu Shipyard built for the Three Gorges Project.
After tensely waiting for nearly half a day, they finally received a response from the experts.
On the phone, the expert laughed: "Comrade Xiao Han, from the drawings, your design concept is very advanced, and your water quality requirents are very high. Under normal circumstances, using a propeller-based mixing thod for chemical addition, multi-stage net agitator for flocculation, siphoning for sludge removal, followed by filtration, 40-degree inclined-tube sedintation, and then chlorination, should et the drinking water standards. Is there a need to further process with the not-so-mature ultrafiltration technology on top of these processes?"
"Master Shi, we aren’t overdoing it. This is what we considered."
Han Yu raised his head to the equally anxious Boss Wang and others, tightly gripping the phone as he explained: "What we are modifying is a waterworks ship for flood control and ergency water supply, not a normal water intake and treatnt floating waterworks. Our waterworks ship either doesn’t get used, or if it’s put into use, it’s certain the raw water quality we can obtain would have been polluted, with possibly even higher sedint content than usual several tis over."
The expert pondered for a mont and said: "If the raw water is polluted, further processing is necessary. However, ultrafiltration technology is not very mature; are you confident?"
"Dostically, it isn’t very mature, but it’s already quite mature abroad. Last year, we overhauled an international vessel; it had a water purification system utilizing ultrafiltration technology."
"Equipnt?"
"The equipnt isn’t complex; we maintained that system during the overhaul."
"But your waterworks ship is so small. If you use ultrafiltration for secondary processing, can it achieve the daily 100-ton design requirent?"
"Master Shi, we plan to use the water produced by traditional processes for dostic use, like bathing and laundry. The water processed with the ultrafiltration system would be used for drinking purposes, and this should et the design requirents."
"Classifying the water is an interesting approach."
"Master Shi, this is our first ti modifying a waterworks ship, and we have no prior experience. Do you think our design plan is feasible?"
"The water processing technology flow has no issues, but there are two points to be aware of."
"Which two points?" Han Yu quickly picked up a pen, ready to take notes.
The expert looked at the drawings, touched his mouth corner, and said: "First, net agitator flocculation uses multi-stage net agitators, gradually reducing stirring speed, creating relative flow between the water and agitators. Different micro-vortexes and trailing eddies provide ample conditions for flocculation, but note the water flow distribution within net agitators may cause unevenness.
Additionally, the waterworks ship is a floating body, highly affected by wind, waves, and its own weight. You have so many water tanks of varying water quantities, and during water processing, these keep changing water levels. This will cause differences in the draft depth between port and starboard, bow, and stern.
This will not only affect the overall stability and even safety of the ship but also result in the motor drive shafts for the water processing equipnt being frequently eccentric, leading to potential chanical failures of several motors and gearboxes. Therefore, I suggest you reevaluate and optimize the overall layout and ballast asures."
As soon as the expert spoke, it was clear he knew what he was talking about.
Although considering dividing that many water tanks, with varying water amounts in each, causing imbalance in the ship, adopting fixed ballast, they never considered that the motor drive shafts for the water processing equipnt might be eccentric.
If any major motor breaks down, forget net agitator flocculation, even the water pumps might shut down. What water processing then?
Han Yu was grateful for consulting the expert and hurriedly said, "Thank you, Master Shi, for your valuable suggestions. We will further demonstrate and study."
"It’s not really a valuable suggestion, just a humble opinion. I am not on site and don’t know the equipnt situation you plan to use, so I can only strategize on paper. You should first study and demonstrate, and if there are any issues, you can call ."
"Okay, thank you."
...
Every profession has its specialization.
It seems that all we can do is manage so maintenance; design is indeed not our forte.
Han Yu didn’t dare to overestimate his abilities and quickly sought help from the Engineering Departnt of the Cosco Shipyard, inviting several engineers from Cosco to co over for a "technical challenge."
Seven or eight people worked together on it until after 8 p.m., finally optimizing a relatively stable plan based on the original design.
Building a water plant on a 1,200-ton ship is essentially like "holding a ceremony in a snail shell"; whoever cos can’t make it perfect. It is foreseeable that there will be various faults after the modification, which can only be fixed by my brother-in-law’s repair team by then.
In fact, this is also the reason for inviting my brother-in-law to participate in the design and to be involved throughout the modification and construction process.
It’s not just the "Water Plant Ship Team" working on the "technical challenge," but also the "Cookship Team" and "Ergency Power Supply Team."
Even Zhang Erxiao is working on the nu for the entire camp of officers and soldiers during the ergency rescue mission: what to eat in the morning, how many dishes at noon, and what soup at noon. The nutrition must be ensured, the budget cannot be exceeded, and efficiency must be emphasized.
My brother-in-law and sister-in-law are similarly studying what dical equipnt and dicines are needed for performing tasks locally, and what dical equipnt and dicines are needed for performing tasks in other locations...
Only Xiao Yu was carefree, treating the excavator like a big toy and playing around joyfully.
Han Yu rushed back from Boss Wang’s Shipyard to the camp’s main entrance, only to see that it was dark and Xiao Yu still hadn’t returned to Bailong Port, continuing to "work under the lamp" outside the camp!
"Are you addicted to playing? Get down here, don’t you realize what ti it is now!"
"I’m not playing, I’m repairing the road."
Xiao Yu stopped the engine, parked, jumped down, and proudly pointed behind him, saying, "Salted Fish, don’t you think this road at our main entrance should be repaired?"
"Where’s Master Huang?"
"He went back."
"Master Huang went back, and you’re daring enough to operate this on your own?"
"Salted Fish, operating an excavator isn’t as difficult as you think. Master Huang is right; anyone who can drive a car and operate a loader can get the hang of it in half a day. But operating it well is not easy. For instance, when arriving at a site, you need to first think about how to get across the ditch, how to carry out the construction, anyway, operating this requires talent, and I have a knack for it!"
"Look how smug you are."
"It’s true; simply leveling the site is really simple."
Xiao Yu grinned and pointed across the almost completed Yanjiang Road, "Salted Fish, I’ve decided, after repairing this section north of the road, I’ll go repair the southern section, and continue all the way to the riverbank. And then build a gentle slope over by the riverbank, so large vehicles can drive up there."
Han Yu was indeed a bit envious of him, the kind of guy who can play when he wants to, not worrying too much, and still can get promoted and get a raise. So he smiled and asked, "And then?"
"Then build another slope over there at the riverbank, paving the road to the river beach. When they train in a few days, we can’t just let them train and study without any labor. By then, I’ll have Zhang Erxiao and Xiao Jiang act as my assistants, have them go to nearby construction sites to fetch so yellow sand, gravel, and cent to pave the leveled road into a concrete road and cast a bridge pier by the riverbank. So the next ti it rains, we won’t have to take the muddy path to the dunship."
"That’s a major project!"
"With an excavator, it’s simple."
"Operating an excavator may be simple and not tiring for you, but isn’t it hard work for the others acting as assistants?"
"Being a soldier is about enduring hardship. When I was in the police academy, I often took recruits out for voluntary work."
The dunship was relocated over here, and the steel floating bridge was set up just like that on the river beach. The road conditions on the shore weren’t good, especially during rainy days when it would turn muddy—a difficult path to traverse.
Han Yu thought Xiao Yu’s idea of repairing the road was not bad and smiled, saying, "The training plan is decided by the instructor and administrator. Ask them tomorrow whether they can arrange so labor ti."
