please check!The "Period Examination" transcript of the Chengdu Metro Construction Project is here

More than 30,000 builders fought quickly and sweating, accelerating the construction of line construction today, Chengdu Rail Group reported the latest construction progress: At present, the fourth phase of Chengdu rail transit construction planning lines and rail transit the Ziyang line have 56 blocks. At the top of the station, 59 stations entered the main structure of the main structure.

☆ Line 30 Phase I

The first interval dual -line penetration

Recently, as the "New Journey 7" shield machine knife is broken out, the dumpling tree station -Jinyi Station interval is smoothly connected, marking the first shield interval of the first phase of the rail transit line 30 Realize dual -line penetration.

The Duzi Tree Station — The shield range of the Jinyi Station is 825 meters. The crossing of the stratum is a local clamp clay clay floor, a stroke stratum layer and a composite formation. Along the interval, wearing the square in front of the Chengdong Automobile Passenger Transport Center Station, and the construction of the Third Ring Road Chengren, and other construction buildings.

"In order to ensure the efficient and safety of the shield digging into, we pay close attention to the management of the shield to dig into the entire process of management, organize the participating parties to investigate, study and formulate a crossing plan, improve the evaluation of experts, strictly accept the acceptance of safety conditions, and implement the management of duty; regularly hold molding management tubes The film quality summary analysis meeting, strictly select the tube film selection and assembly quality control; take measures such as decomposition management and setting prizes per loop work to improve the efficiency and quality of shield excavation. "The relevant person in charge of Chengdu Rail Group said.

As of now, the first phase of the project shield of Line 30 has accumulated 17 wells, with 16 departures, and 6 stations have been capped. 13 stations have entered the main structure construction stage.

☆ Line 27 Phase 1

The first elevated area bridge

Recently, the first elevated range of the first phase of the rail transit line 27 -Shimenkan to San Sheng Temple was successfully connected.

The first phase of Line 27 is 8.2 kilometers in length, with a total of 6 stations, 7 sections, and crossing the Jinniu area and the new capital area. There are currently 4 stations to achieve capacity and 1 interval bridge.

"During the project construction, the party organization of the Chengdu rail construction management unit and the party organization of the participating units jointly established 13 party member pioneers, 15 young commando and 1 party member commando to overcome the difficulties in the construction process." The person in charge of the first phase of the engineering line of Line 27 introduced.

It is understood that there are currently 12 wells under the shields of the entire line, with 7 departures, 11 stations have been capped, and 12 stations are undergoing main structure construction.

☆ Line 13 Phase 1

Three stations have been capped

On June 28th, the main structure of the San Guantang Station of Line 13 was successfully capped, and the first caps to be capped in the first cap for the line;

On June 29, Wanjiawan Station and Peifeng Station were capped at the same time, and important progress made project construction.

It is understood that the capped San Guantang station was located at the intersection of Longzhou Road and San Guantang Street. It was laid along the Dragon Boat Road and adjacent to Jinjiang. The surrounding residential areas and shops were dense. "In order to greatly reduce the impact of noise, during the project construction, we set up a height of 7.5 meters of sound barriers on the dragon boat road from the main road out of the city to create a good construction environment." Essence At the same time, in order to accelerate the efficiency of the construction of the station and combine the actual conditions of the site, San Guantang stood in advance to plan the allocation of resource allocation in advance and continuously optimize the construction plan. The construction of the pile structure has greatly shortened the overall construction period. At present, there are 9 stations on the first phase of Line 13, and 11 stations have entered the main construction stage.

☆ Rail Transit Ziyang Line

The first mining method construction tunnel smoothly penetrated

Recently, with the roar of the machine, the export rock formation of the mountains on the south side of Da Gao Temple in the Dagao Village, Dayan Economic Zone of Ziyang City was mechanically bitten, marking the smooth penetration of the first mining method construction tunnel of the rail transit.

Lujiazui Station -The Lintong Economic Zone Station Division Mine Tunnel is located on the north side of the Express Road, the south side of Da Gao Temple, with a length of 226 meters long and 225.654 meters long on the left. In order to ensure the smooth progress of the tunnel construction, the Chengdu Rail Group planned in advance, comprehensively arranged the geological geological geological and landform of the tunnel, refined research on the construction of the site, the construction of the tunnel, and the measurement of the surveillance measurement. , Strictly injection, short excavation, strong support, early closed, diligent measurement "principle, vigorously promote information technology, and timely grasp the sedimentation monitoring data of ground tables and surrounding buildings to guide the construction and improve the safety factor. At the same time, the construction progress is accelerated; the support parameters, construction sequences, and construction methods are summarized in a timely manner, providing technical reference for subsequent construction, and effectively ensuring the smooth penetration of the tunnel.

As of now, there are 6 stations on the rail transit and the main structure of the main structure.

In addition to the above lines, lines No. 8, Phase III, Line 10, and Line No. 17 Phase II are also accelerating. As of now, 9 stations have been capped at the construction line and 59 stations have entered the main structure construction stage.
