Description

Technical Field

[0001] The utility model relates to a grouting device for a railway cable trough cover plate, belonging to the technical field of railway construction. Background Art

[0002] The newly built Shenyang-Baihe Railway, located in Liaoning Province and southern Jilin Province in Northeast China, serves as a regional connector for the main corridors of the "Eight Vertical and Eight Horizontal" high-speed railway network. It holds significant significance for promoting the comprehensive revitalization of Northeast China and achieving high-quality regional economic development. With the rapid development of high-speed rail technology, the use of high-speed rail cable trough covers, as a crucial component of the system, has become particularly important. However, traditional cable trough cover installation operations present numerous challenges, such as inconvenience and low efficiency. Therefore, improving and optimizing these installations is a pressing issue. China Railway Construction Electrification Bureau Group Second Engineering Co., Ltd., based on the Shenyang-Baihe High-Speed ​​Railway project, conducted an investigation and study of the cable trough cover installation process. The team found that the primary cause of the low efficiency of cable trough cover installation is the use of mortar caulking and bonding during the later stages of installation. During the installation of railway cable trough covers, mortar is typically used to secure the covers to the cable trough and prevent loosening or falling apart. In the existing laying process, people need to squat on the ground and slowly spread the mortar, which has low laying efficiency, high mortar waste rate and high labor cost. If the operation is not standardized, the safety risk is high, which affects the overall construction progress. Utility Model Content
