At this time, if you divide the entire Qingdao urban area from top to bottom, you can see a miraculous scene;

Under the ground of tall buildings and streets, the first thing that appears is about 0.8 meters deep power and communication pipes.

Underneath this are stormwater pipes that are not less than 1 meter deep, and sewer pipes that are even deeper.

In the middle of these pipelines, there are vertical and horizontal water supply pipes with different depths ranging from 1 to 2.5 meters, depending on the water pressure.

And underneath all of this, there is a three-meter-deep gas pipeline.

All of these lifelines are intertwined in a way that is not in absolute order, and that every district or even street is different. It is like a huge root system rooted in the city, and the roots only go in all directions and do not develop underground.

But!

Below all these intertwined pipes, about six meters underground. A clear and straight pipeline with the railway power supply terminal as the source, with an absolute straight line, an average to an outrageous depth, and the most concise route, avoids all the underground water layers, and runs through every block of Qingdao City!

These pipes are said to be pipes, but they are two meters in diameter and can accommodate adults to move freely through them without feeling inconvenienced.

At this time, in the tunnel, thigh-thick cables have been laid. At the end of these cables, seven unpainted vole diggers have completed their mission, slowly digging out to the outskirts of the city, waiting for the engineers to dismantle.

……

On the streets of Qingdao, within a certain community. Tuhai Infrastructure and China Railway Electrification Company are two different camps, but the construction units with the same purpose have met.

"Yo he! Aren't these underground drilling experts? Why, digging a hole in the ground is stuffy, and this is to come up to breathe?"

"Haha, don't say that. Digging six meters underground, this amount of work cannot be completed in a day or two. If you stay down there for a long time, you will develop claustrophobia and rheumatism. It's good to come up and walk around often. ”

"No, what do you think? Dig six meters underground to erect a new underground pipeline, just to specially build a power supply network for electric piles and base stations, who made such a brainless, ah, no, genius plan?"

"Of course it's made by people with funny heads!hahahaha,"

As soon as the two parties met each other, the construction personnel of Tuhai Infrastructure laughed.

There are many projects in Tuhai infrastructure, and there are countless projects like this that need to erect pipelines underground.

The most effective way to do this kind of project is to borrow the existing pipeline directly, or erect it separately next to the pipeline of a similar layer. In this way, although the chaos is a little messy, the good thing is that all the pipelines are together. There are traces to follow, the construction is convenient, and it is also convenient to wait for future maintenance and upgrades.

Like China Railway Electrification, it is a construction method that goes directly to the underground, and building an electric pile network is similar to building a subway, not to mention now, even if it is pushed forward for ten years, I have never seen such a stupid, so stupid, so laborious, time-consuming, and costly and unflattering method.

In contrast, Tuhai Infrastructure Group, through its good relationship with the municipal government and the joint support of the power grid and communications, directly borrowed the existing pipeline for cable erection, which seemed to be easy and comfortable.

As a peer, can you not laugh at it?

But to their disappointment, after this ridicule, the faces of the construction workers of China Railway Electrification did not show the embarrassment and discomfort they hoped to see.

On the contrary, the construction workers in dark blue overalls looked back as if they were looking at idiots.

"Well, I told you that you don't understand, whatever you think. In short, it's good if you're happy, it's good to be happy," seeing the disdain and ridicule of the people in Tuhai Infrastructure, a construction worker of China Railway Electrification said.

Just when Tu Haiji didn't understand what he meant, the sound of a high-power engine came from far and near.

After a while, a huge steel beast that looked like a giant scorpion drove up to the side of the street. The machine stood for nearly three lanes, and after it stopped, the huge "tail" behind it stood tall and was as tall as a three-story building.

The appearance of such machinery in the urban area is simply incomprehensible!

"I'm going to be the Ao, what's going on?"

"Wow! I know this! This thing seems to be the 1911 that repaired Metro Line 1 in Fuzhou City before!"

"What is this thing going to do in the city?"

As if in response to everyone's questions, the huge ZXLS1911 unfolded its work top.

What kind of work is that?

If you don't take into account its huge size, it looks almost like an Italian roll. The spiral-shaped structure looks like a big drill bit, but the overly complex head looks like a miniature TBM.

After the top was fully stretched, a magical scene was staged;

I saw that the ZXLS-1911's towering boom began to quickly aim at the opposite side, and then, the long "drill bit" was aimed at a clearing on the side of the street and drilled down!

A large amount of sediment and gravel poured out of the trench of the drill bit, and it took less than fifteen minutes, with a sound of grinding teeth to stop, a hole with a diameter of about one and a half meters and completely perpendicular to the ground appeared in front of everyone!

A construction worker of China Railway Electrification waved his hand at the cab of the steel behemoth, and then took the cable that had been fixed to the side of the street and descended into the vertical hole.

More than ten minutes passed, and the man was hoisted up together with a cable that was erected in the ground at an unknown time, with a thigh-thick cable!

Seeing this, the construction workers of Tuhai infrastructure seemed to realize something.

It was at this time that ZXLS-1911 removed a large number of parts from the back of the carrying bucket.

The staff received and carried it to the top of the vertical pit just now, and then ...... Assembled on the spot!

Half an hour later, in the midst of people's mixed eyes of surprise and admiration, a rectangular charging base station covering an area of about five square meters appeared in front of them.

From having nothing on the ground, to digging through the line pipeline channel, to erecting the ground terminal equipment. The whole construction process took less than an hour!

"How is this possible?!"

Seeing this scene, the people of Tuhai Infrastructure were crazy.

"Oh my God, that cable has been in the ground for a long time, when did they dig through the ground?! Dig six meters deeper? Impossible, absolutely impossible!"

"Even if the is here, it's impossible to dig it up in such a short time?"

"What the hell does this Nima use? How can it be so fast to start construction behind us?!"

Seeing the appearance of everyone's madness and subversion of the three views, the construction worker of China Railway Electrification just now smiled shyly again.

"You will definitely see such a scene in the future, you just get used to it, just get used to it......"
