Turnout section rail plate beam production process and turnout rail plate beam manufacturing method
The invention relates to a turnout section rail plate beam production process and a turnout section rail plate beam manufacturing method, a bridge floor of a turnout section rail plate beam is provided with at least two concave turnout steel rail grooves, a plurality of post-tensioned prestressed ducts are reserved in the turnout section rail plate beam, the turnout section rail plate beam is manufactured by adopting an inverse method, and the turnout section rail plate beam manufacturing process comprises the following steps: S1, cleaning a steel mold; the steel die comprises a die cavity, a turnout steel rail channel steel film matched with a turnout steel rail groove is arranged at the bottom of the die cavity, and sleeve holes matched with post-tensioned prestressed ducts are formed in the two ends of the steel die. S2, manufacturing a reinforcement cage, and putting the reinforcement cage into a steel mold; s3, the embedded part is installed, and the post-tensioned prestressed pipeline penetrates through the reinforcement cage and the sleeve hole; s4, concrete is poured into the mold cavity, and vibration and plastering are conducted; s5, tarpaulin temperature control steam curing; s6, pulling out the post-tensioned prestressed pipeline after initial setting of the concrete; and S7, demolding and curing after the concrete strength reaches a certain value. The turnout section rail plate beam is produced through the reverse pouring method, the process is simple, and operation is convenient; and the produced turnout section is not wide or long, so that the turnout section is convenient to transport.
本发明涉及道岔节段轨板梁生产工艺及道岔轨板梁制作方法，道岔节段轨板梁的桥面有至少两道内凹的道岔钢轨槽，道岔节段轨板梁内预留有若干后张预应力孔道，采用反位法制作道岔节段轨板梁，包括以下步骤：S1，钢模清模；钢模包括模腔，模腔底有与道岔钢轨槽适配的道岔钢轨槽钢膜，钢模两端有与后张预应力孔道适配的套管孔；S2，制作钢筋笼，钢筋笼入钢模；S3，安装预埋件，后张预应力管道穿过钢筋笼和套管孔；S4，向模腔内浇筑砼，振捣、抹面；S5，篷布温控蒸养；S6，砼初凝后拔出后张预应力管道；S7，砼强度到达一定值后脱模、养护。本申请采用反位浇筑法生产道岔节段轨板梁，工艺简单，操作方便；生产出的道岔节段宽度不宽或长度不长，便于运输。
