"More than 150 workers are all on duty to seize the golden construction period and ensure the progress of the project. According to Han Jiajun, a technician of the first branch of the Ningma Intercity Railway (Ma'anshan Section), as of now, the main body of the first branch station of the Ningma-Malaysia Intercity Railway has been completed, and the remaining 1 Cihu station is undergoing foundation and foundation beam construction. The pile foundation and cushion cap of the interval bridge have all been completed, the pier body has 1 remaining, the continuous beam has 7 remaining, and the simply supported beam has 11 holes, and the bridge deck of the erected section is under construction synchronously. According to the construction plan, before June 30, the first branch of the Ningma Intercity Railway will complete all the bridge construction, and at the same time complete the construction of the main structure of Cihu Station, laying the foundation for the overall goal of laying tracks for the whole line of Ningma by the end of the year.

According to reports, the first phase of the Ningma Intercity Railway (Ningma City (Suburban) Railway) has a total length of 54.23 kilometers, of which the Ma'anshan section is 27.72 kilometers long, which is a landmark livelihood project in Ma'anshan City. After the completion of the project, it will realize 30-minute access between the urban areas of Ningbo and Maanshan, which is of great significance to promote Ma'anshan to fully connect with the Yangtze River Delta and deeply integrate into the Nanjing metropolitan area.
Chaoma Intercity Railway
"The steel tower M35 block section passed the joint acceptance before hoisting, and it can be lifted!" On May 1, in the Z4 main tower of the main channel bridge of the Ma'anshan Yangtze River Railway Bridge of the Chaoma Intercity Railway undertaken by the China Railway Bridge Bureau, with the order of Zhang Hang, the person in charge of on-site construction, the steel tower weighing 373.5 tons was slowly lifted to a height of 300 meters, and then the docking was successfully completed.

As the control project of Chaoma Intercity Railway, the main channel bridge of Ma'anshan Yangtze River Railway Bridge is a cable-stayed bridge with three towers, two main spans and three cable-faced steel truss girders. Among the three main towers, Z3 and Z5 are A-type side towers, which have been capped, and Z4 main tower is a four-limb space structure, both longitudinal and horizontal are A-type, and the tower is 345.6 meters high, of which the upper tower column steel tower is 118.5 meters high. The construction of the steel tower is divided into 39 sections for hoisting, and the construction has started since 10 last year.

In order not to affect the construction period of the whole bridge, all the employees involved in the construction of the Z4 main tower have been sticking to the construction site since October last year and implementing 24-hour uninterrupted construction. At present, the steel tower has been constructed to the 35th section, and the remaining 4 steel towers strive to complete the hoisting and achieve capping by the end of May. "The construction period of the steel tower directly affects the progress of the next girder. During this year's May Day holiday, we have a total of more than 100 employees who stick to the construction line of the Z4 main tower, and are in full swing to prepare for the hoisting of the steel tower and the erection of double cantilever steel beams. Zhang Hang said.

"The construction of steel towers is a key process in the construction of the bridge, and it is also one of the major difficulties. In order to ensure the quality and safety of steel tower installation, we use the world's most advanced 15,000-ton-meter tower crane for lifting. Ruan Ningbo, Minister of Machinery of the Project Department, said that the crane is a tower crane tailored for the Ma'anshan Yangtze River Railway Bridge, with a maximum lifting capacity of 600 tons, which is equivalent to lifting 400 cars at the same time, effectively solving the construction problems such as heavy lifting components, high lifting height and large operating span.
At the construction site of the Z3 main tower, which is not far from the Z4 main tower, more than 100 builders are also working on the erection of single cantilever steel girders and the hanging of cable-stayed cables. The reporter learned that the Z3 main tower has a total of 16 sections of steel beams, 13 sections have been erected, and 30 pairs of cable-stayed cables have been completed, 180 pieces.
