Chapter 566 Voluntary labor
As far as the customs is concerned, it doesn't matter where the smuggled excavators seized are parked, as long as they are not lost.As for whether Han Yu will use it or not, it doesn't matter if it's worn out, it's second-hand anyway.

In short, Director Zeng readily agreed to the proposal to park the excavator in the reserve battalion.

Han Yu was thinking about where to find a flatbed truck to pull it. "Brother Hao" who had been paying attention to this all the time took the initiative to ask Ying to arrange a flatbed truck to pull it back.

He knew that Xiaoyu wanted to learn about excavators, so he arranged for an old driver from the company to come and teach him.

While teaching Xiaoyu the excavator, the master inspected the excavator carefully and confirmed that although the excavator is second-hand, it is well maintained. The engine and hydraulic system are original, so it is certain It has not been overhauled, and if you pay attention to maintenance in the future, it will be fine for another ten years.

"Brother Hao" became more interested. He called and repeatedly emphasized that "the fat and water should not flow into outsiders' fields", and entrusted Han Yu with full authority to "keep" this excavator well, and he must take it down when the customs handle it.

Han Yu can't take care of these things now, and he doesn't even have time to learn excavators with Xiaoyu. He has been in Changyu Shipyard for two days. The engineer, and his brother-in-law Zhang Jiangkun and other engineers and technicians studied how to build a floating water plant capable of emergency water supply on the basis of a 1000-[-]-ton inland river cargo ship that was almost dismantled.

Water intake and pressurization are not problems, the key is the process of water production.

In fact, water production is water purification, and there are no technical problems. It can be said that the existing water purification technology is very mature.

The waterworks on the shore, the seawater desalination and purification equipment on the ocean ship, the Guzhou Shuishang Waterworks on the other side of the river... all the technologies used by others can be used for reference.

Industry specializing in surgery.

"This is a big project!"

Building a water plant on a 1000-[-]-ton ship is basically "doing a dojo in a snail shell". No matter who comes, it is impossible to achieve perfection. It is conceivable that one or another failure will definitely occur after the refit. It can be solved by brother-in-law's emergency repair team.

Xiaoyu turned off the fire and stopped the car, jumped down and pointed proudly behind him: "Salted fish, don't you think the road at our gate should not be repaired?"

It is not only the "Waterworks Ship Team", but also the "Cooking Ship Team" and "Emergency Power Supply Team" who are conducting "technical research".

If a few large motors fail, not to mention the flocculation of the mesh paddle, I am afraid that even a few water pumps will lie down, so what water is produced?

"But your waterworks ship is so small, if you use ultrafiltration technology for secondary processing, can it meet the design requirement of [-] tons per day?"

Seven or eight people studied until after [-] o'clock in the evening, and finally optimized a relatively safe plan based on the original design plan.

Han Yu didn't dare to trust him, so he hurriedly asked for help from the engineering department of COSCO Shipyard, and invited several engineers from COSCO to come over to carry out "technical research".

"It's not a valuable opinion, it's just a simple opinion. I'm not at the scene, so I don't know the equipment you plan to use, so I can only talk about it on paper. You should research and demonstrate first, and if you have any questions, you can call me."

"Master Huang has gone back, do you dare to drive alone?"

Although I considered separating so many water tanks before, the water in each water tank is not the same, which will cause the hull to be unbalanced, so I used fixed counterweights, and I never thought that the drive shafts of the motors of the water making equipment would have problems. May be eccentric.

Furthermore, the waterworks ship is a floating body, which is greatly affected by wind, waves and its own weight, and you have to install so many water tanks, the water volume of each tank is different, and it will even change continuously during the water production process.This will cause the inside and outside sides of the ship, the draft of the bow and stern cannot be consistent.

The expert pondered for a moment, then said: "The quality of the raw water is polluted, so further processing is necessary, but the ultrafiltration technology is not very mature, are you sure?"

……

"Where's Master Huang?"

Only Xiaoyu was heartless and had a great time playing with the excavator as a big toy.

"The equipment is not complicated, we have maintained that equipment during the overhaul."

With a total investment of 20 yuan, Han Yu was not at ease after thinking about it, so he called a friend at the hydrological station of the Yangtze River Water Conservancy Commission and asked them to help contact the experts from the Design Institute of the Yangtze River Water Conservancy Commission, and then faxed the design drawings to ask the experts to help Check it out.

The expert looked at the drawing, touched the corner of his mouth and said: "First of all, the flocculation of net paddles is to reduce the agitation speed step by step through multi-stage net paddles, so that the water flow and the net paddles have a relative orbital movement, and the different micro-vortexes and The wake around the flow provides sufficient conditions for flocculation, but it must be noted that the distribution of water flow energy in the mesh paddle will lead to poor uniformity.

"I'm not playing, I'm building roads."

"Mr. Shi, this is the first time we have refitted a waterworks ship, and we have no previous experience. Do you think our design plan will work?"

The key point is that the space for 1000 [-]-ton inland cargo ships is too small, and the waterworks ships required by the two reserve battalions are not designed to produce less than [-] tons of clean water per day, because once they are refitted and put into use, they may not be guaranteed. It's just the domestic water for two battalions of three hundred officers and soldiers.

The Design Institute of the Yangtze River Water Conservancy Commission is very professional in this area. The large waterworks ships built by Hanwu Shipyard for the Three Gorges Project were designed by them.

"Where's the equipment?"

"OK, thanks."

Xiaoyu grinned, and pointed to the road across the river that was about to be completed: "Salted fish, I've made up my mind. After the north section of the highway is finished, I'll repair the south section all the way to the river embankment. Build a gentle slope on the other side of the embankment, and then the cart can drive up."

"gone back."

"With an excavator, it's very simple."

"It is not very mature in China, but it is very mature abroad. We overhauled a foreign ship last year, and the water purification device on that foreign ship adopted ultrafiltration technology."

"Which two points?" Han Yu hurriedly picked up his pen, ready to take notes.

It seems that people like myself can only do maintenance, not design.

"That's right, it's really easy to simply level the field."

As soon as the expert opens his mouth, he will know whether there is one.

He laughed on the phone and said, "Comrade Xiaohan, from the blueprints, we can see that your design idea is very advanced, and the requirements for water quality are also very high. Normally, the dosing is mixed with pusher propellers, and the chlorine is added with multi-stage mesh paddles." After flocculation and siphon sludge removal, it should be filtered, then sedimented in a [-]-degree inclined tube, and chlorine should be added to meet the drinking water standard. It is necessary to use the not very mature ultrafiltration technology to further Processing?"

In fact, this is also the reason why my brother-in-law was invited to participate in the design, and then to participate in the whole modification construction.

"Dried salted fish, the excavator is not as difficult as you think. Master Huang is right, as long as you can drive and drive a loader, you can get started in half a day. But it is not easy to drive. For example, when you arrive at a construction site, you must first think about it. How to cross the ditch, how to construct, anyway, it takes talent to drive this, and I have the talent to drive this!"

The brother-in-law and sister-in-law are also studying what medical equipment and medicines need to be prepared for local missions, and what medical equipment and medicines need to be prepared for missions in other places...

"Then build a slope on the other side of the river embankment and build the road to the river beach. Isn't it necessary to train in a few days? We can't let them just train and study without working. Let Zhang Erxiao and Xiao Jiang give them I work as a small worker and ask them to go to the nearby construction site to pull some yellow sand, stones and cement, pour the smoothed road into a concrete road for me, and then pour a pontoon bridge pier on the side of the river embankment. In the future, when it rains, we will When you get on the barge, you don’t have to walk the dirt road.”

After two days of repeated arguments, I finally came up with a plan.

"It's interesting to grade the moisture level."

Han Yu was really envious of him, he could play as much as he wanted, he didn't have to worry so much, and he could get a promotion and salary increase, so he couldn't help but asked with a smile, "Then what?"

After waiting nervously for nearly half a day, the expert finally got a reply.

This will not only affect the stability and safety of the whole ship, but also cause the motor drive shaft of the water-making equipment to be in an eccentric state, which will cause mechanical failures of several motors and reducers. The counterweight measure design is further demonstrated and optimized. "

"There is nothing wrong with the process of water production, but there are two points to pay attention to."

Even Zhang Erxiao was studying the menus of the officers and soldiers of the whole battalion during the rescue mission, what to eat in the morning, what dishes to eat at noon, and what soup to eat at noon.Meat and vegetables must be matched, nutrition must be guaranteed, funds must not exceed, and efficiency must be paid attention to.

"Look what you are proud of."

Han Yu looked up at Boss Wang and the others who were also nervous, and clasped the phone tightly, explaining: "We are refitting a water plant ship for emergency water supply for flood control and emergency rescue, not a water plant for water production under normal circumstances. Our water plant The factory ships are either not put into use, as long as we use the raw water we can get, the water quality will definitely be polluted, and the sediment content may be several times that of usual.”

Han Yu rushed from Boss Wang's shipyard to the gate of the camp, only to see that he hadn't returned to Bailonggang after dark, and was still "playing with lights at night" outside the camp!
"Are you addicted to playing? Come down for me, and don't even look at what time it is!"

"Mr. Shi, we are not adding to the liking, this is what we think about it."

Han Yu was very fortunate to have consulted an expert, and hurriedly said: "Thank you, Mr. Shi, for your valuable advice. We will discuss and study again."

"Mr. Shi, we plan to use the purified water produced by the traditional process as domestic water, that is, for bathing and washing clothes. We use the water that is secondary processed by the ultrafiltration device as drinking water. This way, it should meet the design requirements."

"Your excavator is very simple, and it is not tiring. If you let others do small jobs, are they tired?"

"Being a soldier is hard work. When I was in the police academy, I often took students out to do voluntary labor."

The barges moved over, and the steel pontoon bridge was erected on the river beach. The road conditions on the shore were not good, especially in rainy days, when it would become muddy, it was not easy to walk.

Han Yu felt that Xiaoyu's idea of ​​building the road was good, and said with a smile, "The training plan is formulated by the trainers and administrators. You can ask them tomorrow if they can arrange some labor time."
