Jixian high -speed rail Shandong section's largest rotor continuous beam rotation is completed

Qilu.com • Lightning News, June 27th. On June 27th, the Jixian High -speed Railway Bridge, which was established by the China Construction Eighth Bureau, spanned Beijing -Kowloon and Handji Railway (72+128+72) M turning in continuous beam to construction. The successful completion, this is also the largest continuous beam to the Shandong section of the Jixian high -speed rail. The completion of the rotary construction will further promote the construction of the high -speed rail of Jizheng, and create favorable conditions for the next step of the construction of the beams and no orbital rails and related stations.

Cross Beijing -Kowloon, Handji Railway (72+128+72) M rotate continuous beams of 273.7 meters, the bridge deck is 12.6 meters wide, the main pier height is 10 meters, and the weight of a single T structure is 11,100 tons. Two T components require "zero errors" together. In order to achieve accurate docking, the two main pier T structures are trapped by two 300 tons jacks, hydraulic pumping stations and other rotary equipment. 79 degrees, finally completed the combination of two "giants".

Behind the "Big Mac" turntable is all fine jobs. The turntable construction is supported by the ball hinge. The intelligent continuous pound of the beam is controlled through the main console. Monitor the wind speed to ensure that the rotor construction progress is controllable, the appearance accuracy is accurate, and the safety factor meets the standard.

The continuous beam of the construction of this construction spans the Beijing -Kowloon and the Handji Railway at the same time. The train is operating at a high density, the skylight time is limited, and the construction level is high. In order to ensure the successful completion of the turn, the third -point plan of the Jixian High -speed Railway of the Eighth Bureau of China Construction Eighth Bureau was planned in advance, and the simulation rotor was carried out many times to determine the blockade of the construction plan. This turns adopt the "construction first and then turn" method. In the direction of the parallel railway, the padding method is used for the construction of two main pier T structures, and then the beam body is transferred to the preset position. Construction of cross -dragon section. Earlier, the project team has successfully completed the construction task of continuous beams of the cross -bodies across the Hanji Railway (59+98+59) M, which has accumulated valuable experience for this successful transfer.

The construction of the Shandong section of the Jixian high -speed rail began in June 2020, with a total length of 168.391 kilometers. The second bidding section of the Eighth Bureau of China Construction Eighth Bureau was 80.736 kilometers. The important part of the comprehensive transportation channel of the five consecutive companies. The construction of all consecutive beams is planned in August 2022, and the rail paving began in November 2022.

After the completion of the high -speed railway, the high -speed rail will become a fast passenger channel connected between the Central Plains urban agglomeration and the Shandong Peninsula urban agglomeration. It is of great significance to give full play to the advantages of economic and social and tourism resources along the line and build a modern high -rail network.
