The two of them began to work. At first, Lao Zhou thought that Li Wei was a theoretical player.

I immediately noticed that it was different.

Li Wei's technique is simply more skilled than him! Take the laying of this extruded plastic board as an example, his ten years of old workers are not as fast as Li Wei's laying!

The most important thing is that Li Wei is not only fast, but also smooth!

Lao Zhou who watched it was shocked: "Brother, your technique...... I can't practice it in ten or eight years!"

After listening to Lao Zhou's words, Li Wei was proud.

This is a skill produced by the system, can it be compared to your wild way?

What is a unique job?

The unique job is to engage in this project for a lifetime, and the lines that can be done with your eyes closed are not bad, and the skills produced by the system are unique!

"It's okay to be so-so," Li Wei was very polite and modest: "It's just a little talented, but in terms of experience, you must not be comparable with Brother Zhou, and you have to take action in person in many places!"

A little sycophant smiled at Lao Zhou's eyebrows, and he glanced at Li Wei again: "The young man has a future! Don't worry, I will call you if you have any work in the future, your skills are much better than my little worker!"

Li Wei: "......"

Ahem, I'm really sorry, that little worker, buddy seems to have robbed you of your job by accident......

Laying geothermal is a technical job.

To outsiders, this thing is to lay a bunch of pipes on the ground, and then the stones, sand and cement are filled in, and the smoothing is finished.

But for real insiders, it is really not so simple to pave the floor heat - otherwise dare to ask for the price of 2400 yuan for 3 days, and this price still belongs to the normal market price, that is, the basic 30 yuan / square.

In Li Wei, a small city in the north, floor heating is just needed.

As soon as the temperature starts to go below zero in November, floor heating can form a gradually decreasing temperature gradient from the soles of the feet to the head indoors, thus giving people the comfort of warm feet and cool heads.

In particular, the ground radiant heating is in line with the fitness theory of "warm feet and cool top" in traditional Chinese medicine, and is the most comfortable heating method at present.

Now water and floor heating on the market is the mainstream, that is, Li Wei is now laying this.

This is the heating company directly heating to the community, and the community is pressurized to the household. The water separator that Li Wei bought before is to divide the pressurized water into several lines, and then circulate the whole room to achieve a constant temperature.

They are now laying the most basic extruded plastic panels, which is the lowest layer of the geothermal heat.

After this layer is laid, there is geothermal cotton, which is something that resembles tin foil.

This step of the process is not difficult, the whole house is paved, nothing to say.

What really begins to pay attention to, that is, the watershed between laymen and insiders, is the next step in the process - leaving expansion joints.

What the layman can see is the material lay.

Insiders pay more attention, because in the process of laying the water floor heating system, the expansion phenomenon of the filling layer when exposed to heat will be especially obvious near the expansion joint, and this expansion phenomenon is not only manifested in the horizontal direction, but also in the vertical direction.

That is, we often call thermal expansion and cold contraction.

If this is not handled well, the creep resistance of the heating coil will gradually weaken after a few years, which will directly affect the service life of the entire heating system.

Once the pipes burst, the entire geothermal system needs to be dismantled and resurfaced.

Therefore, expansion joints are one of the most important links in the process of laying geothermal heat.

"Brother Zhou," the hot cotton was quickly finished, Li Wei didn't wait for Brother Zhou to speak, he took the first step and asked, "What do you need me to do with this step of the expansion joint?"

As soon as he heard Li Wei say the special term expansion joint, Lao Zhou immediately gave a thumbs up: "Okay, brother, it's really professional enough, I know this!"

Li Wei scratched his hair with a smile: "Look at what you said, didn't you work with a good big brother in engineering, you know a little bit." ”

At this time, Lao Zhou completely believed that Li Wei had really done it.

To put it bluntly, geothermal things will be paved and paved well, and it doesn't look like there's much difference, but there are still a lot of differences inside.

If you don't understand it, the construction workers will be foolish, and no one will be able to see it.

But if you really meet someone who understands, you can definitely know at a glance whether this life is good or not.

Although Lao Zhou didn't say that he couldn't work hard, but now that Li Wei really knows how to do it, his attitude is naturally a lot more serious.

"I'll do this," Lao Zhou held a pen in his mouth and said, "Brother, you will help me put a thermos sleeve on the tube later, and this can be used when we start coiling." ”

In actual construction, when the floor heating pipe must pass through the expansion joint, a certain length of insulation sleeve should be used to protect the floor heating coil.

"Understood. Li Wei nodded, and the two began to do their own things.

Lao Zhou began to set up expansion joints.

Expansion joints are generally set at the junction of internal and external walls, columns, doors, etc., simply put, it is a circle around the house and the space transition. Expansion joints are generally made of polystyrene or high-foaming polyethylene foam, walking in a straight line without interruption, and the corners are made of 45° corners.

When the ground area exceeds 30 square meters or the side length exceeds 6 m, expansion joints are generally set at a distance of no more than 6 m, and the width of the expansion joints is not less than 8 mm.

For the journeyman Lao Zhou, the progress of this process is still very fast.

After all, it's a profession.

The morning ended with the division of labor between the two.

At noon, Li Wei ordered two boxed lunches, and the two sat on a small bench while eating and chatting.

Lao Zhou said: "Brother, it's really good that you helped me today, and the progress is unexpectedly fast." To tell you the truth, if these jobs were to be done by my small job, we wouldn't be able to finish them in a single day. As a result, it was done in only one and a half days today. I guess if we had done it soon, we'd be almost done in two days. ”

Lao Zhou was very happy when he said this.

The work that was originally completed in three days became completed in two days.

What's wrong with the rest of the day?

He's not counting money by the day.
