深江铁路横栏站站房建设取得突破性进展

Core Insights - The construction of the Xihong Station's steel structure for the new Shenjiang Railway has made significant progress with the successful installation of the last 37.6-meter main truss beam, marking a key milestone in the project [1][5]. Group 1: Project Overview - The Xihong Station building covers an area of 9,991 square meters, featuring a core steel structure that includes a cross-line rain canopy and a wind and rain corridor [1]. - The main truss of the cross-line rain canopy spans 37.6 meters, while the steel beam of the wind and rain corridor spans 48 meters, with the heaviest single component weighing 27 tons, equivalent to the weight of 18 family cars [1]. Group 2: Construction Techniques - The project team has innovatively employed a "dual-machine combination + segmented assembly" method, utilizing both crawler cranes and truck cranes to minimize long-distance transportation risks and reduce high-altitude operation risks, thereby shortening the construction period by over 15% [2]. - To address the deformation risk of the 48-meter span wind and rain corridor steel beam, the team implemented a triangular truss "flat beam" lifting method, connecting the beam with five steel cables to balance the load and prevent deformation during lifting, significantly enhancing work efficiency [2]. Group 3: Safety Measures - Prior to construction, the project utilized BIM technology for 10 rounds of construction simulations and established a "smart monitoring + dedicated inspection + graded early warning" safety control system, employing laser radar and high-precision positioning technology for real-time monitoring to avoid high-altitude collision risks [2]. - During the lifting process, the construction team used total stations to monitor the verticality of the truss and implemented dual insurance measures for precise adjustments by high-altitude workers, ensuring that all indicators exceeded design standards [2]. Group 4: Future Developments - The project has completed the installation of 12 main trusses and 24 steel columns, with six large equipment sets deployed [5]. - The focus will now shift to the installation of the metal roof and electromechanical components, aiming to create a safe, controllable, high-quality, and technologically advanced station [5]. - The new Shenjiang Railway is a crucial part of China's "eight vertical and eight horizontal" high-speed rail network, and its completion will enhance the railway traffic network in the Guangdong-Hong Kong-Macao Greater Bay Area, significantly improving regional connectivity [7].
