Groove broaching construction method for passenger tunnel of railway with underneath passing station track
The invention discloses an underpass station track railway passenger tunnel broaching groove construction method which specifically comprises the following steps: S1, setting a working pit, supporting the working pit by adopting drilling piles, arranging a reinforced concrete top beam with the thickness of 1.5 m on the top of each supporting pile, connecting the supporting piles into a whole, arranging double rows of high-pressure jet grouting piles with the diameter of 0.6 m on the outer sides of the drilling piles as waterproof curtains, and forming a waterproof layer on the outer sides of the drilling piles; tube well dewatering is adopted in the working pit; s2, a foundation pit is dug, a guide ditch is dug in the bottom of the foundation pit, a water-collecting well is arranged at the lowest position, water flowing out and accumulated in the foundation pit is guided to enter the water-collecting well, and a water pump is placed to pump well water to a drainage ditch; the invention relates to the technical field of railway passenger tunnel construction. According to the pull trough construction method for the passenger tunnel of the railway passing through the station track, the Larsen steel sheet piles are adopted, in the construction process, due to the fact that the Larsen steel sheet piles are high in strength, low in density, good in water tightness, capable of being recycled, high in construction speed and capable of obtaining good economic benefits, the influence on the surrounding environment is small, and the construction cost is low. And meanwhile, the steel sheet pile is simple in working procedure, convenient to use and short in construction period in the construction process, the whole site can be kept clean, the construction space is saved, and safety and reliability are achieved.
本发明公开了一种下穿股道铁路旅客地道拉槽施工方法，具体包括以下步骤：S1、设置工作坑，工作坑采用钻孔桩支护，支护桩桩顶均设置1.5米厚的钢筋混凝土冠梁，将支护桩连接成整体，钻孔桩外侧设双排直径0.6米高压旋喷桩作为止水帷幕，工作坑采用管井降水；S2、挖造基坑，在基坑底部挖导沟，最低处设置集水井，引导基坑中渗出和积聚的水流进入集水井，安放抽水机抽井水至排水沟；本发明涉及铁路旅客地道施工技术领域。该下穿股道铁路旅客地道拉槽施工方法，采用拉森钢板桩，在施工过程中因其强度高、密度轻、水密性好、能够循环使用，施工速度快且能取得较好的经济效益，不仅对周围环境的影响较小，同时钢板桩在施工过程中因其工序简单、使用方便、工期较短，并能保持现场整体整洁、节省施工空间、安全可靠。
