Chapter 279: Concealed Construction (2/2)

The foundation pit has been constructed, which is 35 meters deep from the ground.

Among them, the civil air defense project is 13 meters and the metal frame is 22 meters.

Fortunately, there are more than one hundred meters from the rock layer, and there is no shallow groundwater belt.

The Mechanical Colossus Type X can ensure the normal construction of the foundation pit bottom, as long as the network diversion canal is planned at the bottom of the foundation pit.

They drained water is diverted to the special excavated storage pit at the side, and the water is discharged by the water pump to ensure the normal construction of the bottom of the foundation pit.

The more you go down; the ground is muddier.

When entering the bottom of the civil air defense project, Ye Qing seemed to walk into a steel jungle that was outside the stars.

The 22-meter-high steel jungle, with the bottom pressed by gravity, and rows of steel wall supports has been firmly caught in the soil.

Walking here, just turn a little two laps, and people with a strong sense of direction will not be able to distinguish between the southeast and the north.

Fortunately, the monsters installed orange lighting on the top, followed by the arrow.

Ye Qing progressing slowly toward the center of the pit to explore the hidden steel chamber.

The truck travels quietly into the passage of the civil air defense project.

Above the ground, a sheet of thick-walled alloy steel plate with a length of 25 meters was forged into a circle by the Mechanical Colossus Type X.

A heavy truck, quietly driving into the channel of the civil defense project.

When the heavy truck disappeared in the intricate passage, the two steel gates driven by motors installed were closed slowly.

The heavy truck eventually stayed next to an emergency food storage room with a sturdy anti-riot door.

Where not only the heavy truck but also the drainage system in the morning and the Mechanical Colossus Type X, which cleaned the building, stopped there.

The giant laborer who has worked hard jump off the truck and climb into the Mechanical Colossus Type X.

In the dim light, the Mechanical Colossus Type X roared, put the mechanical claws into the rear equipment track.

And then locked two black carbide cutting wheels made of a hard alloy from the heavy truck.

Yes, the giant laborer is planning to cut the food storage room in front of it with a cutting wheel to make room for construction.

If you have a super-human perspective, you will find that under the one-meter-thick steel plate concrete in the food storage room.

It is just the secret room built by the monsters with steel walls.

This is the most central part of the foundation pit.

The food storage room stands in other warehouses and cutting off its concrete wall will not destroy the load-bearing structure of civil air defense project.

Cutting has begun!

The hard alloy wheel, instantaneously from static to dynamic, the sound of breaking through the rapid rotation seems to be able to split the eardrum of the person.

As soon as the rotating wheel was close to the concrete wall and was cleaned, it was followed by a dust storm.

”Buzz and Buzz”

The broken concrete dust is sputtered out like water, and finally, after a few minutes later dust storm is scattered in the air.

Along with the huge noise generated by the cutting, the black carbide wheel was quickly inserted into the concrete wall.

When the steel plate was cut into the inner lining, the dust storm turned into a fire and rain, and the strong metal burnt taste spread.

This is a violent cut that ordinary workers simply dare not try.

The giant labor does not seem to care.

Whether the high temperature will burn the cutting wheel because it does not take cooling measures.

Nor does it matter.

The higher the coefficient of friction, the higher the temperature will be.

When the alloy wheel of the right arm cut for a long time, the temperature rises to the level of 1500 degrees.

And the giant armor is operated by the Mechanical Colossus Type X, and the left arm is replaced to continue cutting.

Cemented carbide can maintain structural strength at 1650 degrees.

It is not necessary for the Monster laborer to pursue this limit.

Anyway, replacing the mechanical arm cutting will take less than two seconds.
