Pipeline four company: winter is coming, will spring be far away    

This year, the development of all industries is not very good, and the market competition is fierce. Facing the pressure, the four pipeline companies actively seek the "rescue business" strategy, and use technological innovation to overcome the difficulties of enterprise development.

Strengthen the domestic market with strength

In the past 09 years, the rapid expansion and occupation of the shield giant in the market brought great pressure to the pipeline four company. At the same time, pipeline four companies are constantly breaking through the bottleneck of the development of enterprises. "To build every project to a fine quality project" is the promise of the four company of the pipeline, and is also the trump advantage of the market competition.

In the 5 shield projects of the second line of the second line, the pipeline four company strictly checks the clearance to ensure that the 9485 meter circular link tunnel is completed in advance, and the excellent rate of the project is 100%. At the end of 2014, the company has four pipeline in the West three lines in the middle Yangtze River Shield in the bid to win the title, was currently the most long oil and gas pipeline tunnel construction right.

In 2013 four, Zhejiang pipeline company contracted pipe shield project ahead of schedule in 12 days. The staff said, not because of the living small lost credibility; no market does not exist, there will be no more staff, to the ground, from the little things, do not have.

After two failures in Hangzhou gas the Fuchun River directional drilling, four pipeline companies were invited to participate in expert demonstration. Finally, the vertical curve pipe jacking was used to cross the Fuchun River. The pipeline four company has performed well, and has successfully crossed the Fuchun River in 3 months. Its jacking speed and construction quality have reached the advanced level of the same industry and achieved the advanced level in China.

Push the core technology into the international market

Innovation is a topic that is never out of date, and it is not a guarantee of derailment from the times. Pipeline Bureau conquerconstantly shield jacking trenchless construction field complex difficult problem, the key is to overcome difficulties, be good at summing up innovation.

Nanjing Jinling Petrochemical Yangtze River Shield Project has to overcome the 65 meters deep water pressure shield tunneling, which is the highest water pressure that can be querying in the shield construction in China. Pipeline four company creates shield and tail bearing and main bearing seals and other technologies suitable for high water pressure formation. It successfully solves the problem of water penetration in the 65 meters deep river, and "a shield shield structure with waterproof structure" has been awarded the national patent.

In front of the cold winter, although there are not so many big projects, but the staff are not idle, are busy to "charge" for themselves.

At the base of Langfang, they focus on the management of technical strength, and carry out full-time professional theoretical training for two months, so that employees can enter the classroom and enhance their knowledge level.

On the spot of the Yellow River shield in Ningxia, the four pipeline company tackled the world-class technical problems of shield tunneling tunnel, such as the downstream slope 18%, the upstream slope 16%, the 1 MPa higher water pressure mud circulation, and the material transportation in the tunnel. The technical bottleneck breakthrough, make China oil become after Germany, Japan and other foreign shield giant enterprises, only domestic enterprises grasp the shield construction problems of large slope mud, through the core technology for the Central Asian reserve D line Vakhsh river.

Science and technology and innovation

With the slowdown in the pace of reform of state-owned enterprises, continuous cold in-depth and pipeline construction market coming into the development of the national economy, the four pipeline company responsible Liu Guangren said: "under pressure, we need to" soldier assault "spirit to overcome difficulties, with the innovation of science and technology to integrate resources, to enter the high end business, the focus of the project in the draw, a victory."

The trenchless business of the pipeline bureau can overcome the loose geological structure, complex situation, water rich and easily collapsed formations, and achieve the goal of environmental protection on schedule and zero pollution. At present, the shield is vanguard long distance vertical curve pipe jacking construction technology research, research on 8000 meters long distance shield tunneling and measurement technology, through technological innovation, to achieve monthly target of 260 meters above the shield.
