U-shaped prestressed track beam and construction method thereof
The invention relates to the technical field of rail transit, in particular to a U-shaped prestressed rail beam and a construction method thereof. The structure comprises longitudinal beams, cross beams, limiting devices, connecting blocks and cable protection devices, the longitudinal beams are perpendicular to the ground, and at least one prestressed steel bar is arranged in each of the two longitudinal beams; the cross beam is arranged between the two longitudinal beams; the number of the limiting devices is at least two, and the at least two limiting devices are arranged on the inner side walls of the tops of the two longitudinal beams correspondingly. The connecting block is fixedly arranged on the upper surface of the cross beam, the cable protection device is arranged between the two longitudinal beams, and the cable protection device is detachably connected with the connecting block. The U-shaped prestressed structure is adopted, the spanning capacity is greatly improved, the land area and demolition projects are reduced, the project cost and interference of construction to the line are reduced, the structural durability is good, and noise is low during application and operation.
本发明涉及轨道交通技术领域，具体而言，涉及一种U型预应力轨道梁及其施工方法。所述结构包括纵梁、横梁、限位装置、连接块和电缆防护装置，所述纵梁垂直于地面设置，两根所述纵梁内均分别设置有至少一根预应力钢筋；所述横梁设置在两根所述纵梁之间；所述限位装置设置有至少两个，至少两个所述限位装置分别设置在两根所述纵梁顶部的内侧壁上；所述连接块固定设置在所述横梁上表面，所述电缆防护装置设置在两块所述纵梁之间，所述电缆防护装置与所述连接块可拆卸相连。本发明采用U型预应力结构，大大提高了跨越能力，从而减少了用地面积及拆迁工程，降低了工程造价和施工对沿线的干扰，结构耐久性好，应用运营时噪音少。
