Segmental assembly turnout rail plate beam structure and manufacturing method thereof
The invention relates to a segment-assembled turnout rail plate beam structure and a manufacturing method thereof, the segment-assembled turnout rail plate beam structure comprises a turnout rail plate beam, the bridge floor of the turnout rail plate beam is provided with a turnout steel rail groove which is concavely formed, the turnout rail plate beam is longitudinally divided into a plurality of segments, and a post-tensioned prestressed duct is reserved in each segment; and post-tensioned prestressed tendons sequentially penetrate through the post-tensioned prestressed ducts of the multiple sections, and grouting is performed in the post-tensioned prestressed ducts to longitudinally splice the multiple sections together to form the turnout rail plate beam. The turnout steel rail grooves comprise a pair of main line steel rail grooves and a pair of side line steel rail grooves. The turnout rail plate beam is gradually widened from one end to the other end, and two steel rail grooves are gradually changed into four steel rail grooves in a transition mode. The turnout rail plate beam is of a segment assembly structure. During construction, the sections are transported to a construction site, and assembling construction such as assembling, tensioning and anchor sealing is carried out on the site. And during transportation, each section is not long or wide, so that transportation is facilitated, and the method is particularly suitable for the conditions of limited transportation conditions such as mountain rail transit and the like.
本发明涉及节段拼装道岔轨板梁结构及其制作方法，包括道岔轨板梁，道岔轨板梁的桥面有内凹形成的道岔钢轨槽，所述道岔轨板梁纵向分为多个节段，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形成所述道岔轨板梁。道岔钢轨槽包括一对正线钢轨槽和一对侧线钢轨槽；道岔轨板梁从一端至另一端逐渐变宽，两条钢轨槽逐步过渡变为四条钢轨槽。本申请的道岔轨板梁为节段拼装结构；施工时节段运输至施工现场，于现场进行组拼、张拉、封锚等拼装化施工。在运输时各节段长度不长或宽度不宽，便于运输，尤其适用于山地轨道交通等运输条件有限的情况。
