一种应用于地铁车站轨顶风道的施工方法
摘要：
本发明公开了一种应用于地铁车站轨顶风道的施工方法，包括以下步骤：（1）准备轨顶风道预留钢筋及PVC预留孔洞套管；（2）拼装侧墙模板，侧墙模板拼装完成后，安装侧墙预留插筋；（3）拼装中板模板；（4）风道模板组装；（5）将组装并安装固风道模板及风道墙内模；（6）通过PVC预留套管孔洞浇注砼，对其进行振捣；（7）拆除模板；（8）下一施工段施工。本发明针对后浇风道的具体施工情况，通过预留孔洞的混凝土浇筑方法，有效的解决了后浇风道施工困难的难题，很好的解决了风道的成型质量及精确定位，节省了施工的成本，适宜广泛应用推广。
摘要（英）：

The invention discloses a construction method for a subway station track upwind way. The method comprises the steps that (1) a track upwind way reserved steel bar and a PVC reserved hole sleeve pipe are prepared; (2) side wall template splicing is carried out, and after side wall template splicing is completed, a side wall reserved inserting rib is mounted; (3) middle plate template splicing is carried out; (4) air way template assembling is carried out; (5) air fixing way template and air way wall inner die assembling and mounting are carried out; (6) concrete placing is carried out through a PVC reserved sleeve pipe hole, and vibration is carried out; (7) template detaching is carried out; and (8) next-stage construction is carried out. According to the specific construction situation of a post-placement air way, through a concrete placing method of the reserved hole, the problem of post-placement air way construction difficulty is effectively solved, air way forming quality and accurate locating are well achieved, construction cost is saved, and the method is suitable for wide promotion and application.
