The construction period of the Sichuan Tibet Railway will exceed ten years, what problems have the r

The construction of the Sichuan-Tibet Railway is full of difficulties, and our country's transportation department says that the construction of the railway may take more than 10 years. This also reflects that the whole railway construction process may encounter some difficult problems to solve, and the reason why his construction period is so long is indeed based on the local climatic conditions, as well as the geological complexity to decide, and the amount of this project is relatively large, the span of the Sichuan-Tibet Railway is also relatively large, very long, ten years is also excusable, we can analyze the railway builders in the construction of the Sichuan-Tibet Railway may encounter some problems. <>

Climatic problemsThe Sichuan-Tibet railway has a high latitude and a relatively high altitude, and in this case may encounter some frozen soil conditions, and during the construction of the railway, due to the high altitude of the local area, it will hinder the builders of the railway, because they may have some adverse reactions, and it is very hard to work in that environment, and at the same time to build the railway, so that the difficult things increase the difficulty of their work. At the same time, due to the large range of local climate change, the quality assurance of the completed railway must be guaranteed, so all aspects of climatic factors must be taken into account in the construction process, including the complexity of geology, and if there is frozen soil, it must also be solved. <>

Geological problemsDuring the construction of the Sichuan-Tibet Railway, the span of latitude is very large, and in this case, the climate change is not only complicated, but also the geological aspect is very complicatedTherefore, in some areas it may be necessary to build bridges, and the bridges are to prolong the difficulty of building railways, and also increase the problem of serious engineering quantity, the larger the amount of work, the longer the construction time, these are some problems that will be encountered in the construction process of the Sichuan-Tibet Railway, but at the same time, if it is built, it will definitely have a very good benefit to the local and the residents around the railway. <>

At the same time, because of his large amount of work and long construction period, the relevant departments responsible for providing materials for the construction of the railway and the workers who built the railway have provided a large number of working environments and jobs, and at the same time, they have also brought economic benefits to some enterprises, so there are also some benefits.

First, there is the issue of weather. Because the weather over there is not good, there are often heavy rains. Second, there is the problem of manpower, this railway project is understaffed, so the progress is very slow. Thirdly, the problem of mountains, because there are many mountains, hindering progress.

The local climate change is relatively fast, and the geographical environment is special, there are many mountains, it is difficult to lay railways, and the working environment is relatively difficult.

The topography of the Sichuan-Tibet Railway makes it very difficult to build the railway. Secondly, due to the influence of the weather, many construction workers are not adapted to the environment in the northwest region, resulting in the extension of the construction period.

1. The average altitude of the whole line is about 3,000 meters, and the maximum can reach 5,000 meters, and the air is thin. Therefore, a problem that construction workers have to face is lack of oxygen, various altitude sickness such as headache, insomnia, dyspnea, especially sudden respiratory diseases at high altitude, which can easily cause death.

Second, there are a large number of suture zones on the Sichuan-Tibet railway line, and the suture zone is also the place where the two plates converge, which leads to the complex topography of the region, with a large number of Hengduan Mountains, a large number of mountains and lake basins, which can be said to be high mountains and deep valleys, and the overall topography is high in the west and low in the east. At the same time, the railway also needs to cross the Yalong River, the Lancang River, the Brahmaputra River, the Jinsha River, the Nu River and other five major rivers, especially along the Brahmaputra River, the wind speed can reach up to 12, and in the drought will form wind sand, causing movable mounds.

Third, Ya'an to Nyingchi construction location, in the alpine environment, there are hidden dangers brought by seasonal changes, low temperature construction is a test for construction personnel and construction equipment, coupled with strong ultraviolet radiation, the burden on the human body is extremely heavy, but although the Sichuan-Tibet Railway is in the plateau area, but in the northern tropics, the sun is sufficient, the temperature difference is very large, the temperature in summer can reach up to about 40, the rainfall is abundant, but in winter at minus 20, the temperature difference between day and night is generally 35, such an environment is very easy to cause debris flow and landslides.

The main obstacles encountered in the construction of the Sichuan-Tibet Railway are: the problem of permafrost and the avoidance of nature reserves!

The main obstacles encountered in the construction of the Sichuan-Tibet Railway are the thin air on the plateau, the passage through the permafrost, the complex geological conditions, and the lack of sparsely populated materials.

During the construction of the Sichuan-Tibet Railway, the mountains and rivers encountered are high mountains, especially the snow-capped mountains, and the biggest difficulty is the lack of oxygen in the high mountains, which poses a huge threat to the oxygen of the construction vehicles and personnel

The Sichuan-Tibet railway project needs to face construction problems such as lofty mountains, terrain elevation differences, frequent occurrences, complex geology, seasonal permafrost, mountain disasters, plateau hypoxia, and ecological and environmental protection. The Sichuan-Tibet Railway gathers mountains and hills.

The main obstacle encountered in the construction of the Sichuan-Tibet Railway is the permafrost, which is a very busy technical problem, and it is a problem all over the world, and this problem was finally solved by us.

There are many obstacles encountered in the construction process of the Sichuan-Tibet Railway, the main obstacles are high altitude, difficult construction, relatively steep terrain, and difficult transportation, which has caused many difficulties to the construction.

What are the main obstacles encountered in the construction of the Sichuan-Tibet Railway?I think the main obstacles encountered in the construction of the Sichuan-Tibet Railway are, firstly, the no-man's land, the desert area and the plateau area, which are very dangerous and difficult to build.

What kind of obstacles will be encountered during the construction of the Sichuan-Tibet Railway?Then it is the Sichuan-Tibet Highway, which is built on the Sichuan-Tibet Railway, so he will often encounter some mudslides, landslides, and some geological problems.

Construction of the Sichuan-Tibet Railway.

The biggest difficulties faced.

It is a problem of the altitude difference of the terrain, which even faces 50 km.

Climb a slope of more than 2,000 meters.

What are the main obstacles encountered in the construction of the Sichuan-Tibet Railway? Landslide tunnel collapse. Frozen Salt City. There are many obstacles to groundwater leakage.

The main obstacle encountered in the construction of the Sichuan-Tibet Railway is the complex local geology and the large number of tunnels that need to overcome site instability.

In the process of construction, relatively speaking, there are still many difficulties and obstacles encountered in this railway, especially through the lofty mountains, Hengduan Mountains and other places, his geological structure is very unstable.

The main obstacles encountered in the construction of the Sichuan-Tibet Railway in Shanghai are the high altitude, the ground will be broken between the mountains, and the temperature will drop and become very cold after the altitude is raised.

During the construction of the Sichuan-Tibet Railway, many major obstacles were encountered in the protection of permafrost, as well as the protection of some wild animals.

What are the main obstacles encountered in the construction of the Sichuan-Tibet Railway?The main reason is the lack of water in the sandstorm.

In fact, when the Sichuan-Tibet Railway was built, there were two main difficulties, the first was that the altitude was particularly high, and the 21st was because this part of the Sichuan-Tibet road began to move in October, so it was particularly difficult to mine.

Extreme weather such as low temperature, rain and snow, frozen soil, steep terrain, etc.

During the construction of the Sichuan-Tibet Railway, the main obstacles encountered were rivers, tunnels, and frozen soil.

In fact, when we talk about the Sichuan-Tibet Railway, the main obstacle we encounter is the high altitude of the high mountains, which is difficult to construct, so we have to open the tunnel.

What are the main obstacles encountered in the construction of the Chang-Tibet Railway?This is the plateau, the hypoxic reaction, and the engineering team is not easy to operate.

The Sichuan-Tibet railway started at the end of 2014, and is expected to be fully opened to traffic in 2026, at that time, the traffic distance between Sichuan and Tibet will be greatly reduced, from the previous driving more than 40 hours to about 13 hours after the opening, because of the terrain and other reasons, the Sichuan-Tibet line belongs to the passenger dual-purpose line, the design speed is 160-200km h, will not be very fast, but I believe that with the strength of the motherland, it is normal to speed up in the future.

At the end of 2014, the Linla section and the Chengkang section started construction at both ends, of which the better construction of the Chengya railway is expected to be completed in 2018, the most important Sangzhuling tunnel in the Lalin railway has been officially broken through on January 17, 2018, and the mileage is as long as 1320 kilometers, the most difficult construction of the Kanglin railway is planned to start construction at the end of 2018, and the whole line will be opened to traffic in 2026, which lasted 7 years.

It is very difficult, and there are many strange peaks and steep peaks on the way, and it takes a lot of effort to build it, and a lot of construction equipment is used.

It is really very difficult to build this railway, because after all, the road is bumpy, and there will be all kinds of obstacles, which is completely different from building a railway in the north.

It's very hard. Because the topography of this place is not very good, and the air resources are also very thin.

It's really hard, and I hope it will be built soon.
