The professional technicians of China Railway 18th Bureau Group have been installed and commissioned by the system. The first large-scale hydraulic concrete lining trolley with large section and high technical performance and large-scale submarine ramp in China has been the first submarine ramp in mainland China. The Xiang'an Submarine Road in Xiamen City was officially put into use.
Xiamen Xiang'an Submarine Ramp is the largest ramp in the world with a total length of 5.9 kilometers. It is designed as a two-way six-lane road with a total cost of more than RMB 2 billion. The tunnel excavation adopts advanced CRD method to organize construction, with high technology content and difficult construction. In order to ensure the safety of the construction of the ramp, the overall excellence of the project quality and the acceleration of the construction progress, the China Railway 18th Bureau Group, which is responsible for the construction task, spares no expense in purchasing this large-scale submarine ramp with advanced technology and excellent performance in China. Concrete lining equipment. The car is 10 meters long, 13.5 meters wide and 8.35 meters high. It is mainly composed of a steel plate with high toughness, a steel bracket and a hydraulic power system. This ramp concrete lining trolley is designed as an integral steel formwork structure. It uses hydraulic cylinder automatic demoulding technology. It is supported by screw jacks during construction. The self-propelled walk is completed by electric reducer. All concrete transport is pumped and filled. The most outstanding performance of this equipment is the piping system for pumping concrete. When the concrete enters the main pipeline, the quick and convenient piping system automatically pours the concrete to both sides of the trolley. The thickness of the poured concrete fully meets the construction technical requirements. Thanks to its good two-way adjustment function, it can complete the transition and adjustment very accurately in the construction of the straight line and the curved section, ensuring the shape of the ramp wall and the arch, and achieving the quality and smoothness of the lining. Straight, natural and beautiful.
After several cycles of construction work, this ramp lining trolley fully utilized its advanced technical performance. When walking, lifting, installing and disassembling the formwork and concrete pouring operation, it not only saves labor and time, but also saves material costs, and ensures construction safety, quality and progress. Each group of concrete pouring lining cycle is shortened by 30 hours. For 5 hours, the construction efficiency has been improved by 6 times. It is of great significance for the lining operation of ramp construction in highway, railway and municipal construction in the future, and it has a wide range of promotion value.
