无底座无砟轨道构造
摘要：
无底座无砟轨道构造，旨在有效地降低轨道结构高度和工程造价。它包括由下而上的线下刚性基础(10)、调整层(30)和轨道板(20)，线下刚性基础(10)具有作用于调整层(30)的限位结构。本实用新型的有益效果是，在隧道、桥梁、桩板等线下刚性基础上不设底座轨道结构，从而有效地降低轨道结构高度和工程造价，而且可减少施工工序和提高施工效率。
摘要（英）：

The utility model relates to a no-base ballastless track structure which aims to effectively reduce the height and the construction cost of the track structure. The structure comprises a sub-linear rigid foundation (10), an adjusting layer (30) and a track board (20) from bottom to top; and the sub-linear rigid foundation (10) is provided with a limit structure which acts on the adjusting layer (30). The utility model has the beneficial effects that no base track structure is arranged on tunnels, bridges, pile boards and other sub-linear rigid foundations so as to effectively reduce the height and the construction cost of the track structure, reduce construction procedures and improve the construction efficiency.
