"I know something! When the national crisis is at hand, we must go to the hottest place in the melting pot of this era. This is not only the charm of the front line of the Anti-Japanese War, even if he is only studying there, he is also a part of that line of defense, never flinching, never hesitating, never watching. Forge a new Great Wall with your own flesh and blood at any time. I want to go back to Beiping, and I want to go to the front line of the Anti-Japanese War. Li Fanping's heart was agitated, and he persuaded his family to return to Beiping on the same day.

But when they hurried back to Beiping, they found that Beiping had changed greatly.

Traces of demolition and construction can be seen everywhere.

"It can't be demolished here, the building of this place is unique in the middle of the Ming Dynasty. According to the plan, this place can be retained, and the road can be passed from the side without diversion. Liang Sicheng was holding the planning plan drawn by many big people in their architecture and history departments, and pointed to a dilapidated two-story attic.

"Got it!" Chai Qian waved his hand, and a staff member next to him separated the place and put a big white circle on the painting on the other side. In a clear dividing line, a conspicuous symbol of protection is marked next to the building.

Meng Xiang had already decided in his heart that he wanted to move the political center to Beiping, so naturally Beiping needed to be re-planned and constructed. Meng Xiang, who has been to Beiping several times in later generations, also knows some of the future plans of Beiping and provides a lot of advice.

"This section of the city wall can be demolished for 100 meters, and the removed bricks can be repaired elsewhere, and the city gate over there and the city wall next to it will be preserved and will become part of the city park around the city." Liang Sicheng was impressed by Meng Xiang's idea, but he didn't know that Meng Xiang plagiarized his idea.

Although the walls of Beiping are somewhat damaged, they are still largely preserved. In this plan, the city gates and important parts of the city wall have been preserved, and only a few dozen openings have been opened in some sections of the city wall for access roads.

This time, the planning and renovation of Beiping was first determined by the chessboard-shaped roads and underground facilities.

Considering that the number of vehicles in Beiping will increase in the future, Meng Xiang has simply set aside 12 lanes this time, plus the reserved green belt, the empty places on both sides of the existing road will temporarily become a connected street garden. Underground facilities, Meng Xiang did not want to patch again and again, according to the construction method of the underground passage that Qidu had already begun to implement, directly excavated on both sides of the road, formed two trenches, and set up sewage pipes on one side. Rainwater pipes are installed on one side to separate the discharge of rainwater and sewage.

At the top of them near the ground are various pipeline channels, which are isolated from rainwater and sewage channels, and the space inside is more than two meters high, allowing people to work upright inside. Set up different pipelines at different heights. When the water main is placed directly in the passage space above the storm water pipe, it causes sewage to pollute the tap water when leakage occurs.

The materials used for the construction of these passages come from the base. The special concrete of the base is no longer used to build roads, this novel material is easy to attract the attention of others, although the lack of sophisticated observation instruments, others can not study anything for half a day, but Meng Xiang still canceled the ordinary road construction on the grounds that the natural specialty of the volcano is limited in quantity.

Five cement factories have been built in Qidu, Jinan, and Zaozhuang in the Special Economic Zone, and new equipment has been imported from Germany, Denmark, and the United States, with a cement output of 3,000 tons. The demand for road cement has been temporarily satisfied, and the asphalt resources of the well-connected Americans have been continuously imported, and asphalt roads have become the main roads.

The idle base construction capacity was developed for the construction of feed-type concrete pipes. The nano-fiber concrete of the base has strong expansion resistance and no water seepage, making it an ideal material for all kinds of pipelines. The underground stormwater and sewage pipes are prefabricated from such materials.

"You see those archaeologists are so serious about every clod of soil, and the progress of this work is too slow, right?" Wan Jueji was a little scratched.

"Didn't the boss say it, act according to objective laws, and it doesn't matter about time. They have more time for archaeological research, and we have more time to perfect the underground passage system. The key is to ensure quality and do a century-old project. Guan Daogong smiled and pointed to the deep trench below and said, "I heard that the underground waterways in Paris can be rowed, and we have no problem rowing." ”

He was referring to the main stormwater pipes, which are made of thick masonry, and the six-meter-wide channel is followed by a four-meter-wide stormwater channel at the bottom, and a meter-wide inspection channel on each side. In the section of the North Canal, which is close to the main drain, the passage is wider and boats can enter and exit freely.

He looked behind him, and not far away a section of the top had been added with nano-fiber reinforced concrete with excellent tensile strength. A layer of masonry was built on the top, and the areas and locations were divided according to the needs of various pipelines such as water pipes, gas pipes, heating pipes, telephone lines, and power lines, and they were stuffed into the upper passages of the two parallel trenches.

The pipeline is also convenient, although the machinery and equipment for the manufacture of pipes purchased by the Germans have not yet arrived, and the base does not support the production of these civilian parts, but there are many pipelines on the ship, such as steam pipelines, water pipelines, cable pipe bridges, etc., which can be directly disassembled, and then enter the shipbuilding plant to repair them, continue to disassemble and repair, and ready-made materials of better quality will be available.

Telephone lines and cables, radar stations can directly produce finished products, and the construction of underground facilities does not require speed, but conforms to the production speed of the base, and saves the greatest expenses.

"Look at the back," Guan Daogong pointed farther away, where the underground passage has been covered with soil, and the guardrails and shields on both sides have been removed, and next year the upper part will be sprinkled with grass seeds and flower seeds, transplanted with trees, and become a garden, "Let's build a section, process a section, and finish finishing a section, and then we can directly use a section locally." It doesn't affect the surroundings, what are you anxious about? The meticulousness of other people's archaeology is to not leave regrets for future generations. ”

There may be cultural relics in the three feet of excavation in Beiping City, so archaeological experts follow the construction all the way. Li Ji and Liang Siyong presided over the archaeological work of the underground construction of Beiping City. The two have gone through 26 years of Yangshao and 30 years of excavation of Longshan culture, and have cultivated a group of relatively professional talents.

"After the completion of this project, I am afraid that a detailed underground map of Beiping will be drawn." Li Ji looked at the staff who were busy measuring and cleaning not far away, and smiled. As the father of archaeology in China, few people know about it in later generations. The tide of politics has drowned out many traces of history.

"It seems that those who are engaged in geology together are already compiling such a map, and this time the project contains too much information. Hydrology, soil, archaeology, and geological structures all came together to move forward with the construction team. It's rare that the top is not urging, not just for the face project. As one of the founders of field archaeology in China, Liang Siyong's other identity is Liang Qichao's second son. Since 32 years, he has been suffering from illness, and after treatment and recuperation in the base hospital, he has been basically cured. Unwilling to continue to recuperate, he ran out of the SAR hospital early and ran to Beiping. Today, he had just met with Liang Sicheng, who was planning a building on the ground.

At that time, Liang Sicheng was holding the planning map of Chang'an Avenue and Zhu Qichao instructing the workers to construct.

After the devil came, Chang'an Avenue was changed to East Sanzamen Street and West Sanzamen Street. In the new plan, it was changed back to its original name. In that plan that surprised Liang Siyong, Chang'an Avenue would be the east-west axis of Beiping. Extending out of Dongdan and Xidan, the length is as much as five kilometers, and it is really a ten-mile long street. Widening is also planned for those outside of the East-West List, some small alleys are about to be demolished, and some buildings are being relocated. However, in the planning, what can be retained is retained as much as possible, as long as it does not hinder the opening of traffic. In this way, some archways and city towers have also been preserved. If it really doesn't work, according to Meng Xiang's proposal, it will also be relocated.

When Liang Siyong passed, a group of craftsmen and craftsmen were marking various parts of an archway and preparing to relocate. There are also two cameras set up next to it to record the original appearance and some details of the place.

And these craftsmen gathered from all over the country are not only doing relocation and restoration, but they will also carry out the construction of New Beiping in the next step. According to the new planning drawings, along Chang'an Avenue, buildings such as the Civic Assembly Hall, the Natural History Museum, the History Museum, the Library, the Large Store, and the Grand Theater are about to rise from the ground.

In particular, the square near [***] is so large that it is rare in the world. The size of the pen surprised Liang Siyong.

"It's just planning, it's part of a 10-year plan. Now we are concentrating on fighting to drive the devils out of China, this blueprint for the construction of a new home for our future! Zhu Qichao sighed.

"Commander Meng said well, to do a conscience project, it doesn't matter about time, we have the best, and future generations will save time. The same is true for our archaeology, the more detailed it is, the more detailed it is, the more future generations will be able to see the original appearance of history and understand more history. Li Ji's exclamation interrupted Li Siyong's emotion.

"Our theater has just promulgated the "Law on the Protection of Cultural Relics and Historic Sites", which has issued a special document to protect all kinds of ancient buildings and cultural relics and historic sites, which is more detailed and stricter than that of the central government. This is a great act of kindness! Li Ji said with a smile.

The vast archaeological system of the entire SAR has already begun to unfold.
