Existing line high-speed railway tunnel portal assembled shed tunnel and construction method
The invention belongs to the field of railway tunnel portal protection, and particularly relates to an existing line high-speed railway tunnel portal spliced shed tunnel and a construction method. The assembled shed tunnel stretches across the existing line and is supported by the pile foundations on the two sides; the assembled shed tunnel comprises stand columns, shed tunnel longitudinal beams, shed tunnel cross beams, end protection walls and reinforced concrete slabs. The bottoms of the stand columns are connected with the pile foundations, the shed tunnel longitudinal beams are erected on the tops of the stand columns located on the same side of the existing line, the shed tunnel cross beams stretch across the two ends of the existing line to be erected on the top faces of the shed tunnel longitudinal beams, and the shed tunnel longitudinal beams and the shed tunnel cross beams are fixed in a transverse and longitudinal limiting mode. A circle of end protection wall is arranged in a plane formed by the top surfaces of the shed tunnel cross beams; the reinforced concrete slab is laid on the top surface of the shed tunnel cross beam; under the condition that normal operation of a railway line is not affected, an assembled steel structure is adopted, the original structure is not affected, the process is simple, controllability is good, the situation that dangerous rocks and falling rocks at a tunnel portal damage the line and affect driving is avoided, and the method is suitable for existing line construction.
本发明属于铁路隧道口防护领域，具体涉及一种既有线高速铁路隧道口拼装式棚洞及施工方法；拼装式棚洞横跨既有线通过两侧的桩基支撑；拼装式棚洞包括立柱、棚洞纵梁、棚洞横梁、端护墙和钢筋混凝土板；立柱的柱底与桩基连接，棚洞纵梁搭置在位于既有线同侧的立柱的柱顶，棚洞横梁横跨既有线两端搭在棚洞纵梁顶面，棚洞纵梁和棚洞横梁均采用横、纵向限位固定；端护墙在棚洞横梁的顶面组成的平面内设置一圈；钢筋混凝土板铺设在棚洞横梁顶面；在不影响铁路线路正常运营的情况下通过采用拼装式钢结构，不会对原有结构产生影响，工艺简单，可控性好，避免隧道口危岩落石对线路造成损坏影响行车，适用于既有线施工。
