Chengdu Metro Line 19 Phase II

There are new progress!

In the early morning of July 29, with the last pair of rails in the interval of Wenjiashan Station -Muhua Road Station, the second phase of the Chengdu Rail Transit Line No. 19 achieved a "short rail".

In the rail construction, "short rails" refers to the laying of a 25 -meter -long rail of 25 meters, forming a continuous track. When these rails are seamlessly welded, the "long track" is achieved. As the iconic node of rail paving operations, the smooth realization of the "short rails" created construction conditions as follows of subsequent professional construction, vehicle debugging and other links. Operations laid a solid foundation.

About Line 19 Phase 19 &&

The second phase of Chengdu Rail Transit Line No. 19 is an important rail transit line connecting the Shuangliu International Airport and Tianfu International Airport. After the line is opened, it can expand the core area of Tianfu New District to the double stream and Wenjiang radiation, which is of great significance for Chengdu to build an international comprehensive transportation hub.

Go all the way, spell out the construction acceleration

According to the relevant person in charge of the construction of the second phase of the project in Line 19, Chengdu Rail Group organizes the organization of China Electricity Construction and other participating units, based on the site conditions, optimizes the sequence connection, continuously adjusts the rail launch plan, and creates the construction conditions of the Shuangjing Railway as much as possible, the largest A degree of reduction in construction period;

Coordinate the construction unit to increase the investment in personnel and equipment. During the peak of the rail paving period, 25 rail paving work surfaces are opened. More than 2,100 workers work at the same time, and invest in more than 220 (sets) of various types of rail paving equipment to effectively ensure the construction progress;

Innovative construction technology, for the first time the Chengdu rail transit was applied to a new prefabricated board bed structure, through multiple deductions, multi -party reviews, and multi -round verification, the optimal equipment selection scheme and concrete transportation scheme were finally determined to effectively ensure the quality of construction.

Keep improving, improve ride comfort

"The design speed of the second phase of the Chengdu Rail Transit Line 19 is 160km/h, which is currently the highest design speed of the domestic rail transit, which puts forward higher requirements for the construction quality of rail labels." The relevant person in charge of the construction of the second phase of Line 19.

In order to ensure the comfort of the ride during the operation, during the construction process, Chengdu Rail Group strictly observed the materials and acceptance, concealed engineering acceptance, concrete pouring, etc. to ensure the implementation of the quality goals; Rail control network (CP Ⅲ) refinement technology; and adopt a variety of high -precision technologies such as hierarchical vibration reduction and noise reduction measures to configure medium, high, and special vibration reduction locations to ensure the smooth operation of the train.

At present, the second phase of the Chengdu Rail Transit Line No. 19 is promoting follow -up projects such as the installation and decoration of electromechanical equipment in an orderly manner in accordance with the overall project planning.
