Secondary pouring type track structure suitable for monorail tunnel and construction method
The invention discloses a secondary pouring type track structure suitable for a monorail tunnel and a construction method, and belongs to the technical field of straddle type monorail tunnels, the secondary pouring type track structure comprises a base formed by pouring on a tunnel bottom plate, a plurality of beam body units arranged on the base and sequentially arranged in the longitudinal direction, and secondary pouring layers poured on the beam body units, according to the track beam structure, a secondary pouring layer is arranged on the periphery of a beam body unit to form a complete track beam structure, a secondary pouring layer is arranged on the periphery of the beam body unit to achieve accurate control over the line type and smoothness of a vehicle running face on the track beam, the beam body unit is of a prefabricated structure so that transportation and site construction can be facilitated, and furthermore, the invention further provides a construction method. Preliminary positioning adjustment of a track structure is achieved through installation of a beam body unit, and secondary adjustment is achieved through accurate installation of a formwork and re-checking correction after pouring forming in subsequent secondary pouring layer construction, so that the smoothness of a walking surface of an obtained track beam is finally guaranteed, and the line type meets actual requirements.
本发明公开了一种适用于单轨隧道的二次浇筑型轨道结构及施工方法，属于跨座式单轨隧道技术领域，包括在隧道底板上浇筑形成的底座和设置在底座上，且沿纵向依次排列设置的多个梁体单元，并浇筑在梁体单元上的二次浇筑层，以形成完整的轨道梁结构，通过在梁体单元外周布置二次浇筑层，以实现对轨道梁上的车辆行驶面的线型及平顺性进行精准控制，且梁体单元为预制结构，以方便运输和现场施工，进一步地，还提出了一种施工方法，其通过梁体单元的安装设置，实现轨道结构的初步定位调整，而在后续的二次浇筑层施工中，其通过支模的精确安装以及浇筑成型后的复核校正，实现二次调整，以最终保证得到的轨道梁走行面的平顺性以及线型符合实际要求。
