Segmental assembled turnout box girder structure and manufacturing method thereof
The invention relates to a segment-assembled turnout box girder structure and a manufacturing method thereof, the segment-assembled turnout box girder structure comprises a turnout box girder, a steel rail groove is formed in a bridge floor of the turnout box girder in a concave manner, the turnout box girder is divided into a plurality of segments, and a post-tensioned prestressed duct is reserved in each segment; the post-tensioned prestressed tendons sequentially penetrate through the post-tensioned prestressed ducts of the multiple sections, and grouting is conducted in the post-tensioned prestressed ducts to longitudinally assemble the multiple sections together. According to the turnout box girder, the steel rails are embedded in the steel rail grooves, the turnout box girder can continuously support the steel rails, vibration is small, and noise is low; the vehicle comfort is improved, and the service life of the vehicle and lines is prolonged; the track and bridge functions are integrated, the workload is saved, the construction cost is reduced, and the cost performance is high; segmental transportation and on-site assembly can be adopted, and the device is particularly suitable for the conditions such as mountain rail transit with limited transportation conditions.
本发明涉及节段拼装道岔箱梁结构及其制作方法，包括道岔箱梁，所述道岔箱梁桥面有内凹形成的钢轨槽，所述道岔箱梁分为多个节段，每个节段内预留有后张预应力孔道；后张预应力钢筋束依次穿在所述多个节段的后张预应力孔道内，并向后张预应力孔道内灌浆将所述多个节段纵向拼装在一起。使用本申请的道岔箱梁，钢轨埋入钢轨槽中，道岔箱梁可对钢轨进行连续支撑，振动小、噪音小；车辆舒适性提高，车辆及线路寿命提高；本申请将轨道和桥梁功能“二合一”，节省了工作量，降低了工程造价，性价比高；可采用节段运输，现场拼装，尤其适用于山地轨道交通等运输条件有限的情况。
