A pleasant life in a courtyard

Chapter 368 The First Subway

BJ’s first subway is also the first subway in China.

As early as 1953, it was included in the "Plan and Draft for the Reconstruction and Expansion of BJ City" proposed by the BJ Municipal Party Committee.

However, the road to BJ subway construction is full of difficulties.

Because they had no experience, some Soviet engineers who were involved in subway construction were invited to BJ to participate in the preparatory work for the subway.

Even thousands of Chinese students were sent to the Soviet Union to study subway construction and write a complete plan for our country's subway construction.

But by the time further action was taken, five years had passed.

In 1958, the Ministry of Railways established the BJ Subway Engineering Bureau, which further refined the draft plan and conducted planning and design plans, construction plan research and engineering experiments.

At this time, the domestic experience of this kind of long-distance large-scale underground operation is still only on paper.

Moreover, during the geological survey, experts concluded that the geological structural conditions of BJ are very special.

The steel cylindrical piece above wanted to be broken into two flowers, so naturally it had to be invested in more important projects.

After many discussions and research demonstrations, the preparatory team decided to bury all the BJ subway tracks in the Tertiary strata, and designed six different tunnel burial depth plans for this purpose.

In the endless deductions and experiments, time flashed to three years later.

At that time, many small and medium-sized project plans that had been stopped before were put forward again because of the availability of funding sources.

The soil quality of the Quaternary strata is relatively loose and is not suitable for excavation of subway tunnels.

After the disaster passed, not only did the domestic economy improve, but the foreign exchange earned also gave the country a surplus of food in its ever-depleted wallet.

If there are funds for subway construction, it is better to invest them in other urgently needed projects to do more practical things for the people across the country.

If solutions to these uncertain factors are not prepared in advance, once problems are encountered during construction, the consequences will be catastrophic.

The decisive point is mainly military needs.

Of course, mega projects like the subway project have little to do with Li Xiang.

To put it bluntly, we are still poor.

The Tertiary strata are also in a barely adequate state, and water can easily seep in if you are not careful.

In 1961, due to natural disasters and national economic adjustments, the subway project was forced to be cancelled.

Among them, Li Xiang’s project played a big role in earning foreign exchange.

Relevant personnel are cautious and cautious, precise and precise, even for a single number in the plan.

Therefore, it is natural for anyone except the project team to stop a project that takes a long time, requires a lot of investment, is not profitable, and is not sure to start.

Many people who knew where the money came from would laugh and call Li Xiang "God of Wealth" when they met him. Everyone remembered this sentiment.

At this time, the country's various infrastructure projects were still in their infancy. For "high-tech" technical work such as subway construction, they not only had no money, but also no experience and confidence.

Time flew by again, and we came to 1965.

Even if there was no money at that time, the superiors would have to grit their teeth to squeeze it out.

The construction of a subway project is very complex, requiring a large amount of manpower, material and financial resources. It also requires sufficiently advanced technology and a long operation cycle. After the construction is completed, the maintenance and upkeep of the subway infrastructure must be considered, which is a huge investment. overhead.

In the "Report on the Construction of Underground Railway in BJ", it was clearly stated that the construction policy should be adapted to "mainly military needs, while taking into account urban transportation".

And the comments from the big leaders are: "Carefully designed and carefully constructed. During the construction process, there will definitely be many mistakes and failures. Please pay attention to corrections at any time."

The leadership's attitude affirmed the strategic importance of this project.

Construction was about to start. In order to boost morale, the Ministry of Railways even adapted the leaders' comments into a song.

The title of the song is "Careful Design, Careful Construction". The lyrics are exactly what was said in the criticism, not a word has been changed.

Later, when the workers were tired from work or encountered difficulties during the construction process, everyone liked to sing this song to cheer them up.

At 7 a.m. on July 1, the groundbreaking ceremony for the first phase of the BJ subway project was held at Yuquan Road in the western suburbs of BJ.

Important leaders from Germany and DX, as well as relevant ministries, commissions, troops and relevant units in BJ City attended the groundbreaking ceremony.

At that time, Li Xiang was also fortunate enough to be invited to participate, although he only stood in the back row and watched from a distance.

But for this kind of engineering ceremony involving more than ten thousand people, just having the opportunity to be part of it is already an honor.

The first phase of the subway project has a total length of 23.6 kilometers, with 17 stations and a ground depot.

All railways adopt the construction method of open grading and shallow burial. The burial depth is generally 3 to 5 meters, with the maximum depth of 13 meters.

The cave body is a reinforced concrete structure with extremely strong protective capabilities.

Participating units include the Underground Railway Engineering Bureau of the Ministry of Railways, the 12th Railway Corps Division, the BJ City Construction Engineering Bureau, the BJ City Municipal Engineering Bureau and other units.

These are the main ones, and there are other units that play auxiliary roles, too numerous to mention.

The total number of participants reached 4.

Li Xiang's unit is among them, and he will help them solve the problem of upgrading and replacing some machine parts in the future.

Otherwise, Li Xiang would not have the chance to attend the groundbreaking ceremony.

I asked you to come here, but I didn’t ask you to come and watch. You will always be useful.

The preliminary preparations for this project were troubled.

However, once the higher-ups make up their minds to do something, it will be implemented very quickly.

After four years and three months of intense construction, it was officially completed on October 69, 10, and the project began to be completed and debugged.

This debugging lasted two years.

It was not until 1971 that this subway began internal operation.

The operating section is a little shorter than the original planned section, from the "Gongzhufen" West Third Ring Road to the "BJ Station" East Second Ring Road, passing through 10 stations, and the length is a little over 10 kilometers.

Citizens can apply and conduct test rides in an organized manner.

On the first day it was opened to the public, Li Xiang, who had a pass, took his family to experience the ride.

On the first day, surprisingly there weren’t many people at the station.

Many interested people could only watch outside the station.

"Brother, this is the subway." Sitting in the car, Li Xiaodi felt that the subway was both a bus and a train. He felt that it was very magical.

His thoughts at this time were the same as those of the general public: how could the car still be driven underground?

Li Xiaodi, who has never been to other places, has never had the opportunity to take a train and experience the charm of the tunnel.

Otherwise, he would not have been so surprised when he took the subway before and experienced trains passing through tunnels.

The other people in the family are tougher on face than Little Brother Li.

But when I got to the end, I looked at the time and realized that such a long distance only took a cup of tea.

Only then did everyone realize how good the subway is.
