History will write as follows: At present, Erlangshan Tunnel, the tunnel with the highest altitude and the deepest burial depth in China, has been basically completed and put into trial operation.
Years of dreams have come true. Cheers thundered and colorful flags fluttered. ...
Erlang Mountain, abrupt, with an altitude of 3213m; Heavy snow, heavy rain and dense fog last for half a year; Landslides, collapses and mudslides continue all year round. Passing vehicles are "like the gates of hell". The economy of Ganzi and Ya 'an is largely restricted by this traffic bottleneck.
Only by opening the Erlang Mountain Tunnel can the driving conditions in Erlang Mountain be really improved. 1995, with the joint efforts of provincial party committees, governments and people's congresses, the Ministry of Communications finally officially approved the optimization plan for the construction of Erlangshan Tunnel, and included it in the National Ninth Five-Year Plan.
On May 23rd, 1996, Erlangshan Tunnel was officially started! Ganzi and Ya 'an have listed this project as "Hope Project" and "No.1 Project" to promote local economic development, giving full support and cooperation and doing their best to provide good services. The two places set up the "Erlangshan Tunnel Construction Coordination Leading Group" headed by local and state party committees or government leaders, and selected right-hand men to form a special office to cooperate with the construction site all the year round to ensure the construction of the project.
"For the sake of engineering construction, it is not a problem to sacrifice some local interests!" This is a popular slogan in the two places, and it is also the code of conduct of the governments and people of the two places-the maximum preferential treatment for construction land, first used and then levied (approved by the Provincial Bureau of Land and Resources); If you need to cut down a tree, cut it first and then pay for it. The construction land provided by tianquan county costs only 2,500 yuan per mu.
In July, 1997, both the east exit and the west exit of the tunnel were flooded. The news reached Ya 'an, and Yang, secretary of the prefectural party committee, led the responsible comrades of relevant departments to rush to the disaster site at the mouth of the cave overnight to inspect the disaster situation and deliver relief materials in time. In order to restore the construction of the project as soon as possible, Ganzi Prefecture helped the Fifth Division of the Sixteenth Railway Bureau to solve the loan of more than 2 million yuan and transport more than 80 cubic meters of timber to support the construction site. Due to flash floods, roads in tianquan county were interrupted, and the construction workers of the No.1 Armed Police Traffic Corps ran out of food and vegetables. Ya 'an City Coordination Office, tianquan county County Party Committee and County Government immediately organized manpower to deliver rice, pork and vegetables to the construction site in time after understanding the situation, thus ensuring the life of construction workers.

Perseverance, pragmatism, scientific progress and dedication-this is the new "Erlang Mountain Spirit" created by the builders of Erlang Mountain Tunnel.
Erlang Mountain has complex geology, broken rocks and frequent landslides. Erlangshan tunnel passes through eight major faults, dozens of caves, underground rivers, rock bursts and more than 2,000 meters of large deformation and high confined water area ... The construction is not only arduous and dangerous, but also technically difficult.
The eastern construction team, composed of three tunnel bureaus of the Ministry of Railways and the tunnel regiment of the First Armed Police Traffic Corps, and the western construction team, composed of five engineering bureaus of the Ministry of Railways, walked in opposite directions, determined to gnaw this "hard bone".
1March, 1998, when the construction of the east-west section broke through the pebble and sand accumulation layer and was driven to the depth of 1000 meters, rock bursts suddenly occurred one after another. With a loud noise, the stone with a big bowl mouth separated from the cave wall and flew out, injuring more than 20 people successively. Therefore, the excavation progress has dropped from 4 meters per day to more than 1 meter.
According to this progress, when can we get through Erlang Mountain? !
"Science and courage, through the rockburst!" "Decisive battle for 90 days, get through Erlang Mountain!" Three and five places in the east and west sections shouted loud slogans. They invited experts to work with the director's office and the resident supervisor to study countermeasures and prescribe the right medicine. * * * party member set an example, where there is danger, there will be. Li Zhen, deputy manager of the West Section Project, has been living in the mouth of the cave on duty, dealing with problems in construction at any time. After three months of fighting, they finally succeeded in passing through the rockburst area.
At the east entrance of Erlangshan Tunnel, the Tunnel Bureau of the Ministry of Railways made trouble, and there were officers and men of the Tunnel Brigade of the First Armed Police Traffic Corps. They have just moved from Fujian's low-altitude coastal areas to the east entrance of Erlangshan Tunnel at an altitude of 2 182 meters. Not adapted to the cold and humid climate, many people keep working when they are sick. In order to seize the construction period and catch up with the progress, they often put aside their personal interests and emotions. 199965438+In February, the father of Wang Riquan, the instructor of the group, passed away. After receiving the telegram from home, he quietly put it under his pillow in order not to affect his work.
It's hard to dig a tunnel in Erlang Mountain, but no matter how difficult it is, they always insist on quality first. According to the inspection of relevant departments, the center error is only 5 mm and the elevation error is only 56 mm after the tunnel is completed, which is far lower than the allowable error in the specification. Up to now, all sub-projects 100% are qualified, and the excellent and good rate is over 90%.

"To get through the Erlang Mountain Tunnel, it is necessary to put golden wings on the economic take-off of Tibetan areas."
"The opening of Erlangshan Tunnel will certainly promote the economic complementarity between Ya 'an and Ganzi, promote the cooperation between Tibet and China, and build a prosperous and powerful ethnic corridor. "
This is a hopeful prediction of Ganzi and Ya 'an policy makers.
One end of Erlangshan tunnel is connected with the mainland, and the other end is connected with Ganzi Tibetan area. Its economic and political significance is self-evident.
Ganzi Prefecture is rich in natural resources, especially tourism resources. The completion of Erlangshan Tunnel will accelerate the deep development of this treasure land. 2/before the arrival of kloc-0/century, Ganzi government plans to start the strategy of "rejuvenating the state through tourism": in May 2000, Kangding international mountain transfer meeting will be held in cooperation with the provincial tourism bureau; The "Grassland Golden Autumn Jockey Club" will be held again in autumn. Tourism sets the stage and the economy sings opera. A series of large-scale tourism activities bring not only tourists, but also a wider and deeper opening and development.
Tibetan areas such as Ya 'an and Ganzi have a history of "tea-horse exchange" as early as ancient times, and their economies have always been complementary. Now the trial operation of Erlangshan Tunnel, material exchange and complementary development and utilization of resources will be further strengthened. Therefore, the highway connecting tianquan county and the tunnel in Ya 'an area has been completely transformed and created as a provincial civilized model road.
Lutong Caitong. Ya 'an and Ganzi in 2 1 century are full of hope.
