Zhang Yutian looked at the shape of the goods carried on the heavy truck and laughed silently.

It turned out to be a flood control wall, and judging by the thickness, it should be four pieces stacked together, even if the length is nearly twice as long as their product, what can it be?

There are too many manufacturers in Huaxia to do flood control walls, but how many manufacturers can ensure that the flood control walls are soaked in water for a long time to ensure that metal materials do not rust and rot?

Amano Heavy Industries could not guarantee it, so it had to build an underground maintenance tunnel so that workers could enter the interior and regularly remove rust and replace waterproof rubber strips.

Amano Heavy Industries can't do it, and Zhang Yutian naturally thinks that Giant Beast Heavy Industries can't do it either.

Thinking of this, Zhang Yutian shook his head, he really didn't have a sense of accomplishment at all when he won this time.

Ye Qing got out of the car from Lagonda in the back, directly ignoring Zhang Yutian's gaze.

"Since Mr. Ye is also here, let's start our test. Mayor Qu Kangxin was also puzzled, this doesn't look like something too high-tech.

The first to be tested was Uji Metal Building Materials Co., Ltd.

Their product is a erected flood wall, which is usually close to the ground, and when the water level of the Tianjiang River rises, the flood wall is opened like a gate to resist flooding.

In the first pressure test, at the edge of the large sealed flow trough, the workers of Uji Jinjian used nuts to fix the erected flood control wall at the mouth of the flow channel, and fixed three flood control walls in a row.

After the flood wall was fixed and the staff of the hydraulics laboratory inspected it, they nodded and signaled that the test could begin.

The recording camera was turned on, and the engineer in charge of the test used the walkie-talkie to inform the pressurized chamber: "The pressure has been raised to three megapascals, please report when the pressurization is complete"

For every 10 meters of water depth, the pressure increases by about 0.1 megapascals, and the water level of the Tianjiang River certainly cannot rise by 300 meters.

According to the water level records over the years, the water level of the Tianjiang River in the two sections of the river was the highest in 1957, when the water level rose by 10 meters.

Haitang Island itself has a certain height, so the flood wall is seven meters high, and it can already be afraid of any floods.

However, the water flow of the Tianjiang River is rolling, especially when the upstream gate is opened and the flood is discharged, the impact of the river water should not be underestimated, and the importance of Haitang Island does not need to be described, and the test should naturally be done with the most demanding markings.

The air pressure of three megapascals was quickly loaded, and when the engineer learned of the situation, he said on the walkie-talkie: "Flood wall 01, the test begins." ”

As he spoke, the sound of rushing water waves immediately sounded in the sealed water flow trough.

When the turbulent water rushes out from the flow channel, the flood control wall built by Ujijin also "crunch~crunch~", and slowly closes towards the flow channel under the lifting of hydraulic struts.

Driven by the pressure of three megapascals, the water crashed against the slowly rising flood wall, like a waterfall rushing down against the rocks, splashing and filling the laboratory with mist.

With a bang, the three flood walls were tightly closed in the water flow slot.

Boss Wang of Wuji Jinjian pursed his lips tightly and stood outside the security line with a nervous expression. With a pressure of three megapascals, he asked himself that there was no problem with the installation of a supporting metal baffle, but the sealing strip in the middle and the sealing of the bottom closure were ......

The pressurized test lasts for five minutes, and Boss Wang of Uji Jinjian glanced at his watch and was about to time it.

Who knew that the three flood control walls closed in the flow trough, the second and third sealing strips, suddenly collapsed with a "poof~" sound.

The pressure of the city's water supply network is only 0.3 megapascals, and the water flow with ten times the impact force is like an endless water arrow.

The water arrows hit the porous artificial stone slabs in the rear, and were quickly absorbed and penetrated.

"The sealing strip is not done well, this can be improved. Hehe~" Boss Wang of Wuji Jinjian smiled ashamedly.

The second leak that wanted to be embarrassed appeared, the leakage point was located at the bottom, and the arrow-like water flow hit the hydraulic struts directly, and Boss Wang's face turned green.

This place is leaking, which means that the hydraulic struts and hydraulic pumps are flooded. Boss Wang's expression was already obvious to everyone that their company did not design these two mechanical parts into a waterproof structure.

"Flood Wall 01 Test Failed!" the engineer announced the results with a blank face.

If you fail the first level, you don't have to test it later.

Boss Wang of Wuji Jinjian helplessly defended: "Our company's prediction of one megapascal pressure is enough, and this test is too strict, and the standard has been directly raised by three times." ”

"Haitang Island is too important to Liangjiang, so we naturally have to test it with the strictest standards. The engineer patted Boss Wang's shoulder: "It doesn't matter, it's not difficult to solve the seal." ”

Twenty minutes later, the products of Conch Door Industry were loaded on the test bench.

Their product is bolder, which is a roll-up type like a roller shutter door, which requires manual installation of multiple supports.

The first pressure test barely passed, and their seal design was reasonable, but it fell on the second test of water wave resistance.

Wave after wave of water surged, when the wave level increased to 5 big waves, the wave height was 2.5 meters, the conch door industry's products were slightly deformed by the waves.

"No, No!" the engineer shook his head.

Finally it was the turn of Amano Heavy Industries, and Zhang Yutian felt that competing with these two companies on the same stage was completely insulting to their products.

Their products have been tested for metal fatigue as early as the time of finalization, and they are dynamic high-low and low-cycle fatigue tests.

The power of the test instrument is much more than the power of water. So in this test, Zhang Yutian didn't have any worries.

When their products were installed on the test bench, Ye Qing also asked two huge laborers to untie the cables on the heavy trucks and use the forklifts in the laboratory to carry down the four flood walls.

Zhang Yutian quietly turned his gaze, and Mayor Qu Kangxin also looked at those flood control walls for a moment.

It was a shield twelve meters long and three meters wide, with a streamlined body.

At the bottom of it, two arcs converged into a sharp corner, and in the process of transportation, the sharp corner of the shield-shaped flood wall accidentally scratched the canvas, and with a "bang", the canvas was torn in a huge way.

"Are you a flood control wall?" Zhang Yutian was completely confused: "Twelve meters high, why don't you even have a pedestal, do you plan to wait for the water level of the Tianjiang River to rise, and directly nail this iron plate to the agate rocky beach?"

"You can understand it that way. Ye Qing spread his hands.

"Crazy, you must be crazy. Zhang Yutian felt that the giant beast heavy industry was completely funny, where is this flood control wall, it is clearly an oval shield, no matter how beautiful the shape is, it can be used as a fart.

Not to mention a little bit of automatic mechanical structure, even if it doesn't even have a base.

A solid iron shield, looking at China, there are not 100,000 but 90,000 factories can make it.

It's not funny, it's what to do?(To be continued.) )
