On April 25, 2024, Zhou Xiaoming, chief photographer of Yangzhou Zhenzhou Mansion and Yizheng Grand Wharf, excerpted the information released by the official account platform of "Yizheng City Forum": On April 23, with the start of the pulling machine, the first cushion cap of Ningyang Intercity (Yangzhou Section) - the 187# cushion cap located in the Yipu section officially started construction, and the construction progress of the project was steadily advancing. In addition, the hydraulic drilling rig for the construction of the seepage interception wall of the low tower cable-stayed bridge in the fourth intercity area of Ningyang began the first drill of the seepage interception wall construction, and other mechanical equipment rose with the sound, marking the official start of the seepage interception wall construction.
The bridge cap is an important link connecting the lower pile foundation and the upper bridge pier, which not only completes the process conversion operation, but also lays a solid foundation for the next step of pier and bridge construction. The Yipu section is located between Puxi Station and Yizheng Development Zone Station, and a total of 14 cushion caps are designed, of which the cushion cap of the 187# pier is protected by Larsen IV steel sheet piles, with a protection size of 9.4*8.4 meters and a depth of 9 meters.
According to the person in charge of the project of Ningyang Intercity (Yangzhou Section) No. 3 Work Zone, the construction of the 187# pier steel sheet pile has been completed, and the foundation pit earthwork excavation of the bearing platform is underway, and the design foundation pit depth is 3.28 meters, which is a dangerous project. The project construction technology team has always adhered to the principle of "slotted support, first support and then excavation, layered excavation, and strict prohibition of over-excavation", and has made full preparations from the aspects of engineering geological data, hydrogeological data, construction site environment and above-ground and underground pipeline investigation, measurement and lofting in the adjacent area, giving full play to the advantages of intensive construction, implementing standardized construction site management, and ensuring that the construction is completed with quality and quantity.
In the next step, the Ningyang project management team of the transportation construction management company will continue to firmly establish the main awareness of quality and safety, strengthen the safety management of the construction site, strengthen the sense of responsibility, earnestly grasp the safety production and emergency management, resolutely adhere to the bottom line of project safety production, ensure the safety and quality control of the project, and comprehensively improve the level of project construction management.
It is also reported that:
The hydraulic drilling rig for the construction of the seepage interception wall of the low tower cable-stayed bridge in the fourth intercity area of Ningyang began the first drill of the seepage interception wall construction, and other mechanical equipment rose with the sound, marking the official start of the construction of the seepage interception wall.
The seepage interception wall of the 52# pier of the low tower cable-stayed bridge is 124 meters long and 20.11 meters deep, the seepage interception wall of the 53# pier is 193.4 meters long and 20.05 meters deep, and the 54# pier seepage interception wall is 112 meters long and 23.22 meters deep.
Next, the project department will continue to complete the node tasks of the construction of the seepage interception wall on schedule with high standards and strict requirements, quality and quantity.
