[0002] Against the backdrop of global warming, continued population growth, and increasing environmental concerns, people are becoming increasingly aware of environmental protection, and reducing the impact of buildings on the environment has become a goal they pursue. Green buildings are a key development direction in modern architecture. Adopting green environmental protection concepts in the construction field can not only protect the global environment, but also save energy, reduce operating costs, and promote sustainable economic development.

[0003] Since the reform and opening up, my country's railway construction has made significant progress. The rapid and large-scale development of high-speed rail construction has also led to a continuous increase in my country's demand for concrete materials, resulting in varying degrees of impact on the ecological environment. This is mainly reflected in the significant consumption of environmental resources caused by the water and sand and gravel required for concrete production. Furthermore, the impact of cement on the environment is relatively complex, mainly affecting carbon dioxide emissions.

[0004] Existing ballastless track structures are mainly made of concrete materials. Concrete materials are in high demand, environmental resources are consumed quickly, and environmental pollution is serious. Therefore, it is necessary to study ballastless track structures and materials and seek a low-cost, green and recyclable building material. Utility Model Content

[0013] A further technical solution is that the length of the threaded sleeve is 150 mm, of which 100 mm is embedded in the prefabricated integral track bed plate, and the remaining 50 mm is embedded in the polymer mortar layer.

[0014] A further technical solution is that the center line of the anchor bolt coincides with the center line of the reconstructed long bamboo sleeper.
