Embodiment Construction
[0047] The following is attached Figure 1-10 The application is described in further detail.
[0048] The embodiment of the present application discloses a mountainside railway structure in a debris flow area. combine figure 1 and figure 2 , a railway structure near a mountain in a debris flow area, including a dredging structure for dredging the debris flow. The dredging structure includes a diversion channel structure 1 on the near mountain side that gradually decreases from the near mountain side to the far mountain side, the debris flow aqueduct structure 2 and the far mountain side. The rapids trough structure 3, the diversion trough structure 1 near the mountain, the debris flow aqueduct structure 2 and the rapids trough structure 3 on the far mountain side are interconnected. The debris flow aqueduct structure 2 includes an open hole structure 4 for the railway to pass through.

The invention relates to a debris flow area mountain-side railway structure. The debris flow area mountain-side railway structure comprises a dredging structure used for dredging debris flow, wherein the dredging structure comprises a near-mountain side flow guide groove structure, a debris flow aqueduct structure and a far-mountain side rapid flow groove structure which are gradually lowered from the near-mountain side to the far-mountain side; the near-mountain side flow guide groove structure, the debris flow aqueduct structure and the far-mountain side rapid flow groove structure communicate with one another; and the debris flow aqueduct structure comprises an open cut tunnel structure allowing a railway to penetrate through. The debris flow area mountain-side railway structure has the advantage of preventing the mountain-side railway from being damaged by the debris flow.
Description
technical field [0001] The application relates to the field of railway engineering construction, in particular to a structure and construction method of a mountainside railway in a debris flow area. Background technique [0002] Roadbeds or bridges are often used in mountainous railways near mountains. However, with the frequent occurrence of extreme weather in recent years, especially sudden mudslides have posed a great threat to the operation of railways near mountains. Due to the impact of short-term extreme heavy rainfall, large-scale debris flows will break out in the mountainous area where the existing railway is located. serious loss. Contents of the invention [0003] In the first aspect, in order to prevent the debris flow from seriously affecting the railway in the mountainous area, the application provides a structure for the railway in the area of the debris flow. [0004] A mountainside railway structure in a debris flow area provided by the application ad...
