The old and old railways witnessed the deep friendship between the two peoples

Recently, the construction of the old and old railways can be described as frequent reports. This railway with a total length of more than 1,000 kilometers is not only connected to the stations between the two countries, but also the one -coat water, and the people's relationship is closely connected.

After the opening of the traffic at the end of this year, this friendship, technology, green, and open railway will carry the dreams of the people of the middle and old and old people, through mountains and mountains, and create brilliant.

The Lao and Lao Lao Railway is an important project with the strategic docking of my country's \"Belt and Road\" initiative with the Laos \"Mutual Lock and Lock Country\" strategy. It is also the first China side. Technical standards, using Chinese equipment and directly connected to China Railway Network to connect with China Railway. After being opened to traffic, it only takes more than 3 hours from Kunming, Yunnan to Jinghong to Laos Vientiane.Da transport, the day of the day.

\"Other bid sections start the main line construction, we are still building the road. We have repaired 93 kilometers of construction lanes for the 27.5 kilometers of railway projects, set up the 'stool maintenance classes', and maintenance.\" Yu Wentao, deputy chief engineer of the Yumei Railway Project Department of the China Communications Aviation Bureau.

The bearing of nearly 80 kilometers to the Jingzhai Tunnel Working Area, slim and rugged, run for a few hours. There are many local rain, and the roads are often interrupted. In August 2018, the heavy rainfall, the road was damaged, and the transportation was interrupted. Life materials cannot be delivered, and the construction site becomes a \"island.\" \"We mobilized the backbone to rush into the mountains, carried food and vegetables through the landslide section, and sent it to the work area.\" Yu Wentao said that in recent years, more than 200 \"stool maintenance classes\" have completed the repair task.

The construction experience Construction of the Lao Lao Railway

The epitome of overcoming the difficulties

China Lao Lao Railway domestic Yuxi to Mo Mo The section is located in the south of Yunnan. It is located in the collision stitching belt between the Indian sector and the Eurasian sector.

\"Harm gas, soft rocks, surging water, high ground temperature and other problems frequently emerged, just like building roads in the\" Geological Museum \".\" China Railway Kunming Bureau Group Yunnan Railway Construction Headquarters Commander Liu Yiqiao said.

The temperature in the cave is 40 degrees Celsius, everyone is wearing shorts of shorts; the water is severe, and the construction interruption sometimes reaches one month ... Facing the \"block tiger\" Difficulty.

The stability tunnel jointly constructed by the Fifth Bureau of China Railway and the 19th Bureau of China Railway is the longest tunnel of the Chinese and Old Railway, with a total length of 17476 meters. Difficulty and engineering risks are rare in the construction of domestic railway tunnels.

With a \"bombardment\", thousands of square meters of earth and stones collapsed, and three workers who were performing excavated operations looked back, and the tunnel behind him had been filled. The smoke scattered, and I saw a small gap on the top of the cave, and the three climbed out. \"This is the danger that happened at the end of 2018. The exit section is 1.3 kilometers of strata is mainly charcoal mud rocks. It encounters water into mud porridge, like digging in tofu.\" The chief worker Li Fei said that he had been excavated for more than 10 meters a month, and the danger of collapse and the top continued.

\"Sometimes there are bridges, roads, and tunnels within 1 kilometer, and large machines have to be replaced 3 times.\" Said, we overcome problems such as tight construction periods, difficulty in transportation, and difficulty in organizing implementation to complete the rail paving.

In March 2020, the first 10,000 -meter long tunnel of the China -Laos and Lauret Railway penetrated; in November 2020, the stability tunnel penetrated; in June 2021 Total ... Liu Yiqiao said that the current and old railways are currently undergoing various tasks and make every effort to open up.

Scientific and technological innovation help to overcome difficulties

Steel truss flying rack on the bridge pier, spanning the Yuanjiang River, standing on the bridge between the mountains, it is very Gorgeous. The high pier is the sky, and the steel beam is like a line, standing next to the No. 3 bridge pier with a height of 154 meters and a length of nearly 50 meters at the bottom. The 832 -meter -long Yuanjiang Double Line Bridge is located in the \"V\" -shaped river valley. The height difference between the bridge to the river is about 237 meters, which is a controlled project.

The pier body weighs more than 120,000 tons, plus a steel truss of 21,000 tons. Essence \"The deep terrain of the canyon makes the construction site narrow, there are many faults and landslides, and the foundation cannot bear such weight.\" Zhou Jiawu, chief worker of the Yuanjiang Double Line Bridge project of the China Railway Fourth Bureau, said that two reinforced concrete hollow pier uses the pier beams. The horizontal connection of the \"X\" steel structure with the intermediate \"X\" effectively reduces the weight of the bridge pier.

China Railway Fourth Bureau establishes a monitoring measurement system, using the entire station instrument and GPS device to observe the linear changes, install the strain sheet and correction devices on the pole, use the pier and the vertical and horizontal mobile correction devices With the temperature adjustment method, adjust the longitudinal deviation of the dragon mouth in step to ensure that the main cross -accurate dragon is performed.

Like the Yuanjiang Double Line Bridge, multiple projects break through key technologies, equipment and other problems.

In response to the problems of geological complexity, the participating departments increase the application of information management modules such as the informatization of tunnel advanced geological forecasts to achieve the \"real -time tracking, intelligent control, and timely error correction of construction quality management \"\". The China Railway Kunming Bureau Group organized all parties to conduct technical research, and conducted dynamic design and optimization technical measures for 18 difficult tunnels to achieve \"rock changes.\"

Friends of \"One Tunnel and two countries\"The friendship tunnel is a rare high -erosive salt rock tunnel. \"The length of salt rock is 1410 meters, and the salt contains up to 90%. If the use of ordinary concrete support is easy to be eroded.\" Wang Yufei, head of the Yuluo Railway Project Department of the China Railway Two Bureau, said that after the reporting, the concrete entity lasted 16 months. The intensity is up to standard, and the problem of high corrosion of salt rock is overwhelmed.

Zhou Zhiqiang, Secretary of the Party Working Committee of the Jade Mill Project Department of the China Railway Wuhan Electrification Bureau, said that in the past, data were collected by people, and the data did not penetrate. At present, based on Beidou positioning and infrared scanning technology, the integrated measurement of the construction parameters of contact networks is developed, and the calculation measurement measurement and data sharing are equal to the integration. Construction control and management realize informatization, automation, and intelligence.

Originally, it takes 2 hours to rely on people to set the 500 -meter guidance line, and now 1 hour can plan thousands of kilometers of rail paving path; more than 80 days 500 kilometers ... The 500 -meter -long steel rail paving machine is accurately laid under the guidance of the \"Automatic Patrol Positioning System\" operation mode.

Zhang Xinjin, deputy general manager of the China Railway Kunming Bureau Group, said that the Chinese and Lao Lao Railway is a science and technology road. experience.

\"There are flowers in the eyes, green outside the window, this will be 'people sitting in the car, the car is painting in the painting, the car is in painting, The scene of the Bank of China '. \"Zhang Xinjin said that insisting on construction with resources and environmental protection, treating the ecological environment like life is the principle of following the construction of the middle -aged railway.

Forest dense and wild elephants ... The construction of Yunnan Xishuangna, which is fully preserved in the tropical ecosystem in my country, has strict environmental protection requirements. In response to the protection of wild Asian elephants, all parties will consider the impact of ecological environment as an important factors, investigate the distribution of wild elephants and its migration channels, and analyze the impact. Zhang Xinjin said that the line solution avoids the main activity area of \u200b\u200bthe wild elephant, adopts measures such as extended tunnels, adjusting the position of the oblique well, and a bridge to represent the road to maximize the impact on the wild elephant.

Wild Elephant Valley Station is adjacent to the Nature Reserve. The station design absorbs wild elements. The hall ceiling lamp belt is water spraying nose and footprint shape. \"The two ends of the station are tunnels, and the construction is underground to reduce the impact on the environment.\" Said Wang Junmin, the person in charge of the construction of the wild Xianggu Station in China Railway Construction Group.

The lines of the construction of the Yubo Railway Project Department of China Water Resources Hydropower Railway Projects have about 40 wild elephants in the area through the area. \"In order to prevent wild elephants from destroying railway facilities and affecting the safe operation of construction and subsequent trains, some road sections have been changed to bridge, leaving elephant channels. The road base of construction specially sets 7 culverts for wild elephants.\" In 2019, the construction staff also assisted the relevant parties to rescue a wild elephant who lost their feet into the septic tank.123]

There are tropical rain forests such as the railway in the area of \u200b\u200bthe railway institute. In the construction process, the ecological environmental protection system is strictly implemented, the excavation scheme of soil and stone excavation is rationally optimized, the construction scope is , Reduce the destruction of vegetation. \"The optimization of Shanggang No. 1 Tunnel has canceled the oblique well. It was designed from three excavations to the original work surface and changed to two excavations.\" Said Jiang Caihua, chief worker of the Twenty -five Yubo Railway Project Department of China Railway.
