"Do you know Nanshan?"

Xin Nanshan hurriedly asked, "Is it the blue era of contracting sanitation and tap water?"

"It's 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 should know that he is a user of the Time Blog and has some understanding of a series of companies in the Suiren Group.

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

On the other side.

Zhao Xiaojun and Meng Jianye came to the north of Dongying, where the Dongying North Line water supply pipeline is under construction.

According to the planning and design, the currently constructed pipeline section is a reservoir leading to the northwest.

But now they need to speed up the laying of water pipes, so they cannot use the previous buried pipe type, but the ground type.

As for the problem of freezing in the north in winter, in fact, high-speed flowing pure water will not cause severe freezing due to high-speed flow and the lack of condensation nuclei in the 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 industrial uses a vacuum insulation layer, which is almost the rhythm of the thermos.

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

Meng Jianye looked at his watch: "It can be arrived at noon today. They have transported a batch of equipment in the past few days. The pipes are coming. Today, the last batch of equipment arrives and construction can be started."

The construction company under the Water Company, apart from familiar with the equipment, was pouring concrete bases. A week ago, after notifying them to change the construction method, it did not dig underground ditches.

The concrete base is a structure that is 12 meters long, 4 meters wide, 5 meters high and 5 meters underground depth. It is cast in one piece by solid concrete and steel bars.

According to the strength of the water supply pipeline, a pipeline base is usually set up every 80 meters.

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

The inner diameter of the water supply pipe is 3 meters, and it is made of very high-volume low-carbon steel and is coated with silicon nano-coating. The strength is about 2.1 to 2.3 times that of manganese steel.

If you use stainless steel water pipes of the same specifications, the thickness of the pipe wall is almost three times, and the weight is astonishingly 4.8 times.

You should know that this is a pipe with an inner diameter of 3 meters. If it is modified, it will be more than enough to use it 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 supply pipeline, the construction team left an area to prepare for the construction of a pressurized station. For such pipe water supply, the water company intends to accelerate the delivery of pure water through ultra-high pressure.

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

At around 1:00 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 supply pipelines, the ground pipeline is too large in diameter. If it is manufactured in advance and transported by road, the transportation efficiency of the pipeline will be too low.

Therefore, Snail Industry has specially designed a technical solution for real-time use.

I saw a special engineering vehicle stuffing two thin low-carbon steel plates into the cylinder press of the engineering vehicle through a crane. The thin low-carbon steel plates were pressed into a cylindrical tube in less than five minutes.

A technician from the snail industry entered the inside of the pressing cylinder, and there was a row of holes inside, which was the place where the screws were placed.

Insert screws into the hole, press the fixing frame, press a switch, and then a row of air cannon machines for screwing and nuts are designed at the bottom of the outer side of the pipe.

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

Turn it again and screw it on the other side.

Then another special engineering vehicle, a low-carbon steel pipe with a tail-to-tail connection with the pressing locomotive, was pushed over from the pressing locomotive.

This special engineering vehicle is a vehicle specially designed for electroplating of pipes.

The technician quickly wrapped a silicone film sleeve one after another, which was specially used for parts that did not require electroplating. A part of the pipe must be reserved as a splicing interface.

Soon, the electroplating process was completed and turned into an extremely solid silicon nanosteel pipe.

It was dropped onto the first base by the crane, and the pipe was slowly lowered. The construction staff fixed the pipe with steel cables. In fact, there was a groove on the base itself to ensure that the pipe would not move.

This is the first section of the pipeline, and the next second section is a suspended pipeline, and the construction is different.

After receiving the steel pipe, the electroplating cabin of the electroplating car comes to the bottom of the pipe to be arranged, and then the entire electroplating cabin is lifted upwards and the semi-finished pipe is forced to the interface position of the first section.

Inside the first section of the pipeline, several construction workers drove the sport pipe sealer to the pipe interface to ensure that the pipeline does not leak plating solution.

Soon the electroplating cabin wrapped in the second section of the pipe was started, and the electroplating processing took about 120 seconds to complete the electroplating processing.

The electroplating solution was pulled away, and the electroplating vehicle slowly drove forward, exiting the processed pipes, while another special engineering vehicle followed closely behind. This is a temporary support vehicle, specifically supporting this suspended pipe.

If you draw the gourd accordingly, you can lay a 10-meter pipeline every 20 minutes on average.

Moreover, this laying technology can be carried out at multiple stages at the same time. Even if there is a deviation in the interface between the two stages at that time, it can be adjusted through pipelines to achieve seamless connection.

Currently, the equipment at the construction site can support two places to start construction at the same time.

A construction team and a shift can lay 240 meters of pipes.

A few more construction teams are added to equip these equipment and lay one or two kilometers a day, but there is still little problem.

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

These laid pipes are still semi-finished and need to complete the last step before they are considered complete products.

The last step is to add a vacuum layer, the glass designed with the vacuum layer and the processed silicon nano ultra-thin glass are bonded to the surface of the pipe and fixed with steel strips.

These glass vacuum sheets will be completely combined by re-plating and become a vacuum insulation layer to ensure that the pipeline will not freeze in low temperatures in winter.

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

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

Shandong Province officially subsidizes 2 million yuan per kilometer, and also includes land acquisition compensation costs. The Blue Age only needs to spend 740,000 yuan per kilometer.

With the pressure station along the way, the expenditure budget for this water supply 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 the mouth of the old Huanghe River in Dongying, and asked to prepare to mobilize the engineering team to speed up the second and third phases of the project.
Chapter completed!
