Honsavady.

In the eastern part of Kayin State, on the border between Honsavady and Siam, there is a boundary river between the two countries, the Daung Ong River.

The river is also one of the tributaries of the Salween River.

In the past, when the Weng River was a boundary river, the Aoba Group only dredged it, allowing its ships to pass up to 500~1000 tons.

Not anymore.

Because Siam has become a controlled area of the Homo sapiens company, the boundary river naturally exists in name only.

The river, which had been secretly explored for a long time, had been blocked by a large amount of earth and rock, and the river was temporarily diverted to another location.

After the earth and rock were blocked, a large number of excavators and transport vehicles were busy on the evacuated part of the river.

The Dang Weng River Dam is the heart of the project.

After Liu Zhifan and Wu Nan cut the ribbon below, they were interviewed by TV stations in the two places respectively and were busy until noon, and they had dinner together.

The place where the two of them ate was in the temporary staff town of the construction team, on a flattened hill, and standing on it overlooked the entire construction site.

"Although it is a temporary town, the infrastructure and service facilities are quite complete." After Unan finished speaking, he picked up another chicken cutlet.

Liu Zhifan smiled: "The company has plans for large-scale engineering projects, which require thousands of employees, and there is no problem in building a new town, anyway, it will also need to be built here in the future." ”

Since there were no other outsiders in the private room of the two, Unan spoke more openly, and he looked at the river construction site outside the floor-to-ceiling window:

"The project is planned for three years, will it be too rushed?"

"We didn't rush it, we used new technologies, such as coral cement, which doesn't require much maintenance, as well as iron, bamboo, steel wire composite bars, and most importantly, crack repair technology."

Unan raised his eyebrows and put down the fork in his hand: "New technology again?" ”

Su Jincheng, the chief engineer of the project, introduced to Unan: "Well, during the construction of the building, even if it is not expedited, cracks are a common problem, especially for integrated dams, cracks are almost unavoidable. ”

"And our coral cement is no exception, although the maintenance can be reduced, but there are still cracks, because in recent years, we have rushed to build a large number of hydropower stations, many dams due to improper construction, there are not a few cracks."

Su Jincheng paused and took a sip of water:

"Therefore, the headquarters has developed a set of special crack repair technology for this problem, the core principle of which is to use transgenic fungi, plus special silicate and calcium solutions, to let transgenic fungi grow in the cracks, and then form a highly binding calcium silica layer."

Unan is very interested in this technology: "Does this technology also have the effect of repairing cracks in old reinforced concrete buildings?" ”

"Yes, as long as it is a crack-type failure, it can be quickly repaired in this way, and its adhesion force is much higher than that of the original concrete structure, after all, this is a combination at the molecular level." Su Jincheng nodded.

Liu Zhifan said with a smile: "If it weren't for the fact that the unit cost is 2.7 times that of concrete, and there is a risk of leakage, the company would have planned to build the building in this way." ”

"It's already good, combined with coral cement, iron and bamboo steel wire composite bars, so that we can quickly construct, in fact, three years is including the installation of water turbines, locks and other equipment in the later stage, and the main body of the building only takes about 18 months." Su Jincheng added.

"Does it only take 18 months? This speed is really too fast, and science and technology are really the primary productive forces. Unan sighed.

You must know that the real data of the dam on the Dangung River is quite different from the data they published on TV.

The entire Dangweng River Dam adopts the design of gravity dam, with a length of 1,832 meters and a height of 156 meters, which is a small Three Gorges Dam.

It has a maximum water storage height of 132 meters and a daily water storage height of 100 meters.

This is not the most critical place, the most critical is the navigable lock on one side of this dam, which is designed as a double-line 4-level lock, and the maximum number of ships that can pass is 20,000 tons (1,000 TEUs).

The two announced the figures on TV, but the tonnage of the largest vessel was only 3,000 tons.

Apparently this is a deliberate concealment from the outside world.

This is done mainly to reduce external pressures.

This is because the upper reaches of the Taung Ong River and the largest tributary of the Chao Phraya River in Siam, the Bin River, are less than 20 kilometers away, just separated by a low ridge in the Ta Nen Thanh Ong Mountains.

In the future, after the river dredging is completed, as long as this mountain ridge is dug up, the two rivers can be directly connected.

At that time, the voyage of ships below 20,000 tons from Yangon to Bangkok and Chiang Mai will be shortened from the original 3600~4200 kilometers to 700~1000 kilometers.

This is also the reason why Liu Zhifan specially invited Unan to come over.

If the navigable capacity of the entire canal is to reach the upper limit of 20,000 tons, the Siamese side must also simultaneously transform the Chao Phraya River so that it can be seamlessly connected.

As for why not dig the Kra Canal.

The main thing is that it is not necessary now, and at the same time there is huge external pressure.

The existence of the Strait of Malacca itself involves a complex set of interests and strategies.

Once the Kra Canal is excavated, it will definitely attract the attention of America, and Star Island will even be directly hostile to the Kra Canal.

Therefore, at this stage, the Kra Canal is not necessary.

After all, Homo sapiens now controls Malaysia, at least a quarter of Malacca's sovereignty.

Siam is connected to Honsavaddy by land and Luzon and Malaysia by sea, so the Kra Canal does not need to be rushed.

On the contrary, the Dang Weng-Chao Phraya Canal is even more important because it can promote the integration of Honsavady and Siam, and drive economic development along the route.

After all, the canal connects the northern interior of Siam, making it a smooth route for the Thanah Thanong mountain range, which was supposed to block traffic between the two sides.

The current construction of the Daung Weng River dam to dredge the upstream river, and the construction of the Chao Phraya River dam in Siam are for the final connection of the two rivers.

After Unan knew about this plan, his expression was both excited and apprehensive:

"Mr. Liu, there is no problem with the dredging of the dam and the river, but the section of the mountain range that excavates the Niantaweng Mountains can be easily seen by the eyes of the sky."

"Don't worry! They can't see it. Liu Zhifan replied confidently.

Unan's eyes widened: "How not to be discovered?" Even if it is covered with camouflage cloth, satellites can detect anomalies through the reflected bands. ”

Liu Zhifan wiped his mouth, pushed the dinner plate aside, and then patted Wu Nan on the shoulder: "Let's go to the site together next month to have a look, and the construction team will go over tomorrow to step on the spot." ”

"Mr. Liu really likes to sell Guanzi." Unan was tickled.

Liu Zhifan shook his head: "Seeing is believing, and you may also hear the specific technical principles." ”

"Alright! Then I'll see. ”

The group rested for the night in the staff town and returned to their respective posts the next day.

And the other side.

As soon as the sky turned white, the special engineering team, which had already packed up its equipment, boarded a dozen small transport boats of 500 tons, and drove towards the upper reaches of the Dangweng River.

Although it is the dry season, the dredging of the Dang Weng River can still allow 500-ton boats to sail.

The low ridge was in the middle of the upstream.
