The rise of nanometers

"Nanshan, you know?"

Xin Nanshan asked hurriedly: "Is this the blue era when sanitation and tap water were contracted?"

"This is this company. Do you want to go over and give it a try?" Xin Ailian asked.

Xin Nanshan, who was in a complicated mood, nodded. He naturally had ideas. You must know that he is a user of Time Blog, and he knows more or less about a series of companies in the Suiren department.

The next day, he prepared an electronic resume and submitted it to the Blue Times Shandong Branch.

the other side.

Zhao Xiaojun and Meng Jianye came to the north of Dongying, where the Dongying North Line Water Pipeline is under construction.

According to the planning and design, the pipeline section currently under construction leads to a reservoir in the northwest.

It's just that now they need to speed up the laying of water pipes. They can't use the previous buried pipe type, but must use the above-ground type.

As for the freezing problem in northern winter, in fact, high-speed flowing pure water will not freeze seriously due to the high-speed flow and the lack of condensation nuclei in pure water.

However, just in case, the new silicon nanotubes can actually be equipped with an insulation layer, and the insulation effect is very good, because the insulation layer designed by Snail Industry uses a vacuum insulation layer, which is almost the rhythm of a thermos bottle.

"When will the equipment from Weifang Machinery Factory arrive?"

Meng Jianye looked at his watch: "We can arrive at noon today. They have transported a batch of equipment and pipes over the past few days. The last batch of equipment arrives today, and construction can begin."

The construction company affiliated with the water company was not only familiarizing itself with the equipment but also pouring concrete bases. After notifying them to change the construction method a week ago, they no longer dug underground trenches.

The concrete base is a structure with a length of 12 meters, a width of 4 meters, a height of 5 meters, and a depth of 5 meters underground. It is poured with solid concrete and reinforced steel.

Depending on the strength of the water pipeline, a pipeline base is usually installed every 80 meters or so.

At present, 8 bases have been poured, and 20 bases are still under construction. The 8 bases are about 640 meters long.

The inner diameter of the water pipeline is 3 meters. It is made of low carbon steel with excellent ductility and coated with silicon nano-coating. Its strength is about 2.1 to 2.3 times that of manganese steel.

If a stainless steel water pipe of the same specification is used, the pipe wall thickness is almost three times more and the weight is an astonishing 4.8 times.

You must know that this is a pipe with an inner diameter of 3 meters. If it is modified, it can be used as a room.

If stainless steel pipes are used, the weight requirements for construction machinery are not generally high.

At the interface of the underground water pipeline, the construction team has reserved an area to prepare for the construction of a pressurization station. For this kind of pipeline water transmission, the water company plans to use ultra-high pressure to speed up the transportation of pure water.

The plan is to build two water pipelines, but currently only one can be built first, and the location has been reserved.

At around one o'clock at noon, the convoy from Weifang Machinery Factory finally transported the last batch of equipment to the construction site.

Zhao Xiaojun and Meng Jianye watched the operation of the construction team.

Unlike underground water pipelines, ground pipelines have too large diameters. If they are manufactured in advance and transported by road, the transportation efficiency of the pipelines will be too low.

Therefore, Snail Industry has specially designed a technical solution that is now available and manufactured.

I saw a special engineering vehicle. Two thin low-carbon steel plates were stuffed into the cylindrical press of the engineering vehicle through a crane. The thin low-carbon steel plates were pressed into a circle in less than five minutes. bobbin.

Technicians from Snail Industry enter the inside of the pressed cylinder. There is a row of holes inside, which is where the screws are placed.

Insert the screws into the holes one by one, press the fixing bracket, and press a switch. Then, at the bottom of the outside of the pipe, a row of air cannons for driving screws and nuts is designed.

After a roar, a row of screws at the bottom were locked.

Turn it once more and install the screws on the other side of the interface.

Then another special engineering vehicle was connected end-to-end with the pressing locomotive, and a 10-meter-long mild steel pipe was pushed past the pressing locomotive.

This special engineering vehicle is specially used for electroplating pipes.

The technician quickly wrapped the pipes one behind the other with a layer of silicone film sleeve. This is specially used for parts that do not require electroplating. A portion must be reserved at both ends of the pipe as a splicing interface.

Soon this section of pipe was electroplated and turned into an extremely strong silicon nanosteel pipe.

After being dropped onto the first base by a crane, the pipe was slowly lowered, and construction workers fixed the pipe with steel cables. In fact, there was a groove on the base itself to ensure that the pipe would not shift.

This is the first section of pipeline, and the second section that follows is a suspended pipeline. The construction is different.

After receiving the steel pipe, the electroplating cabin of the electroplating truck came to the bottom of the pipe to be laid out. Then the entire electroplating cabin was lifted upwards and the semi-finished pipe was forced into the first section of the interface.

Inside the first section of pipeline, several construction workers drove the mobile pipeline sealing machine to the pipeline interface to ensure that the pipeline did not leak electroplating solution.

The electroplating chamber that wrapped the second section of the pipeline soon started the electroplating process. It took about 120 seconds for the electroplating process to be completed.

The electroplating liquid was pumped away, and the electroplating truck slowly drove forward to withdraw the processed pipes. Another special engineering vehicle followed closely behind. This was a temporary support vehicle specifically designed to support such suspended pipes.

Following the same pattern, a 10-meter section of pipeline can be laid every 20 minutes or so on average.

Moreover, this kind of laying technology can be carried out in multiple sections at the same time. Even if there is a deviation in the interface of the two sections, the pipeline can be adjusted to achieve a seamless connection.

The equipment currently at the construction site can support two simultaneous starts.

A group of construction teams and one shift can lay 240 meters of pipeline.

If a few more construction teams are added and equipped with these equipment, and they can lay one or two kilometers a day, the problem will not be big.

More than three hours later, two construction teams completed the laying of about 180 meters of pipeline. The more than 70 meters of suspended length between the two bases did not affect the pipeline.

These completed pipelines are still semi-finished products and need to complete the final step before they are considered complete products.

The last process is to add a vacuum layer. The vacuum layer designed glass and processed silicon nano ultra-thin glass are attached to the surface of the pipe piece by piece and fixed with steel strips.

These glass vacuum sheets will be completely combined through electroplating processing again to become a vacuum insulation layer to ensure that the pipes will not freeze at low temperatures due to winter.

Since many parts are produced and sold by ourselves, the comprehensive cost of a three-meter inner diameter water pipeline is about 2.74 million per kilometer.

This cost is already relatively low. According to the planned route from Dongying to Linqing, the total length is about 312 kilometers.

Shandong Province officially subsidizes 2 million yuan per kilometer, and covers land acquisition compensation. In the Blue Era, only 740,000 yuan per kilometer is required.

Including pressure stations along the way, the expenditure budget for this water pipeline is about 500 million.

There was no problem with the pipeline laying. Zhao Xiaojun, Meng Jianye and others came to the desalination plant at Laohuang River Estuary in Dongying to prepare to mobilize the engineering team to speed up the second and third phases of the project.

It is expected that in the next six months, the annual output of the desalination plant will be increased from the previous limit of 180 million cubic meters to the limit of 1.2 billion cubic meters.
