Description

Technical Field

[0001] This invention relates to the field of track construction, and more specifically, to a construction device and method for a sound-absorbing and noise-reducing structure for waiting spaces under high-speed railway tracks. Background Technology

[0002] Some high-speed rail waiting areas are located under the high-speed rail tracks. When constructing such waiting areas, it is necessary to build sound-absorbing and noise-reducing structures on the top to reduce noise from the high-speed rail tracks above.

[0003] As attached Figure 1 The diagram illustrates a sound-absorbing and noise-reducing structure for a waiting space under a high-speed railway track. It comprises a supporting frame with a roof above it. The supporting frame includes horizontal tubes and vertically arranged support pipes. The upper ends of the support pipes connect to the roof, and the lower ends connect to the horizontal tubes. A filling space exists between the supporting frame and the roof. This filling space is a rectangular space formed by the four support pipes, the horizontal tubes, and the lower surface of the roof. This space is used to fill sound-absorbing and noise-reducing material, typically prefabricated modules, which are then assembled into the filling space. The upper surfaces of the prefabricated modules are attached to the roof, and the four corners of the prefabricated modules are attached to the support pipes. Due to the large volume of this material, installation requires both workers and machinery, resulting in poor construction efficiency. Summary of the Invention

The construction mechanism is used to assemble two prefabricated modules into the filling space between the support frame and the roof. The supporting frame includes horizontal tubes and vertically arranged support tubes. The upper end of the support tubes is connected to the top of the cover, and the lower end of the support tubes is connected to the horizontal tubes. The filling space is a cuboid space consisting of four support tubes, horizontal tubes, and the lower surface of the top of the cover. This filling space is used to fill prefabricated modules made of sound-absorbing and noise-reducing materials. The two prefabricated modules are close to each other with sloping sides, and the corners of the two prefabricated modules have notches that match the support pipes.

[0006] Preferably, the construction mechanism includes a support plate, which is arranged horizontally. Two sets of assembly components with identical structures are installed on the support plate. The assembly components include suction plates, which are used to adsorb prefabricated modules. The suction plates are fixedly connected to a rotating shaft, which is arranged horizontally and connected to a rotating component. The rotating shaft is rotatably mounted on the support arm assembly.
