My Doomsday Shelter Unlimited Upgrades

Don't talk about coating anti-corrosion materials, barbecues don't dare to use such materials!

At this moment, Chen Yang began to feel a little distressed.

Survival points are spent too fast!

More than 6000 in the morning.

More than 3000 came back in the afternoon.

Now one flower will change to more than 2000.

It has to be said that only the first two upgrade directions are upgraded.

As for the upgrade direction three or four, there is no need to think about it.

One is temperature control, which is unnecessary, and the other is volume reduction, which cannot be consumed.

But there is no way, and what should be spent can't be saved, so Chen Yang can only grit his teeth and stick out his chest:

"It doesn't matter if you don't get promoted, let's go up!"

[Record]: Survival point -850.

[Upgrading the 'self-made buried water tank' upgrade direction [-] and upgrade direction [-], please wait patiently for the host. 】

......

[Record]: The 'self-made buried water tank' has been upgraded to 'BDF bottomless buried water tank'.

After two or three minutes of upgrading, the water tank in the pit has become an extremely professional water tank.

The original alloy surface layer has disappeared, replaced by a new layer of metal material.

And on the outside of this layer of metal material, there is another layer of anti-corrosion coating that he doesn't recognize.

"BDF tank, what does BDF mean?"

Looking at the introduction of the upgraded water tank, Chen Yang turned on his phone and searched.

"BDF water tank, B is the initial letter of stainless steel, D is the initial letter of hot-dip galvanized sheet, F is the meaning of composite."

"The inside is made of stainless steel and the outside is hot-dip galvanized. It is a new type of buried water tank. It is very easy to use with ginkgo..."

"Professional! So professional!"

Chen Yang called him an expert, but he didn't know what to do.

No matter what this thing is, it's over if it works!

The water tank is done, and the next step is to connect the water pipes.

A water pipe is routed from the ground and is directly connected to a location near the shelter, leading to a mouth.

By pouring water into this mouth, waste water can be loaded into the waste water tank.

An alloy baffle should be installed at the position of the opening.

When the water is not filled at ordinary times, the position of the water pipe mouth is blocked with a baffle to prevent mosquitoes from entering.

Chen Yang didn't want to drink the waste water soaked by mice.

Although a mouse may have been soaked, it's fine if he doesn't know it.

I don’t know, it’s like not having one!

No one knows how to deceive others better than Chen Yang.

The waste water tank also needs to lead out a pipe from the bottom. This pipe is the water outlet of the water tank and is directly connected to the permeation filter on the second floor of the shelter.

This pipe needs to be fitted with a valve.

When you don't need to filter, just turn off the valve, so that the filter will stop working.

Not only that, this step also needs to be pressurized by a water pump.

It is impossible to lead water from the ground to the second floor without pressurization.

Fortunately, his water pump is simple and convenient to use, just connect an extra pipe to it.

This can be modified through the workbench, which costs 100 survival points.

And finally, the pipes of the clean water tank.

Chen Yang only reserved a pipeline, but he didn't connect it anywhere, he just led it out and sealed it.

There is no need to store water in this water tank at present, it is unnecessary to get it, and it is easy to pollute water resources.

When you need it in the future, just pour water directly into the pipe.

Chapter 126 The Roof Collects Rainwater, Anything Can Be 'Requested'

And finally, the design of the rainwater harvesting system.

Chen Yang did a quick search and found that modern rainwater harvesting is mainly divided into three types.

Green space collection, roof collection, pavement collection.

As the name suggests, a rainwater collection pipe is laid under the three places of green space, roof and road.

And this pipeline will be connected to the rainwater treatment system, that is, the water purification system.

After a little consideration, Chen Yang gave up the two methods of green space collection and road surface collection.

Greenfield collection and pavement collection are actually not too different, and both have a fatal shortcoming.

The rainwater on the ground has many impurities and many sources of pollution. If you are not careful, some stones and sand will enter the underground water pipes.

Such water cannot be passed directly to the osmotic filter.

'Filtration' in permeation filters refers to filtration at the molecular level.

As for sand and stones, if the size is too large, it cannot be filtered, and it is easy to block the water inlet of the filter.

That is to say, the rainwater collected by green land and road surface must be settled and discarded before being filtered.

Invisibly, the workload has increased.

The roof collection does not have such disadvantages.
