Embodiment Construction

[0033] In order to make the purpose, structure and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] In order to make the railway track safer, in areas prone to debris flow, protective walls or blocking walls are usually added near the piers of railway bridges to avoid direct erosion or impact damage to the bridge piers caused by debris flow or floods. It is conceivable that in other possible cases, if necessary, a debris flow protection wall or a blocking wall can also be set up, so that the railway is in better safety protection. In fact, debris flows mostly occur in valley areas, and railway tracks are generally placed on railway bridges. Therefore, the scene of railway bridges is taken as an example here, but other possible situations are not limited.

[0035] According to the embodiment of the present invention, the barrier wall provided at the terrain upstre...

Abstract

The invention relates to a monitoring system for debris flow disasters along railway tracks. The alarm system comprises a debris flow information acquisition system, a debris flow information analysis system and an alarm system. Alarm signals and / or intelligence information are / is emitted in one or more modes under the condition that the debris flow information analysis system determines occurrence of debris flow and / or grades of debris flow disasters.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring, in particular to the field of geological disaster monitoring and alarming along railway tracks. More specifically, the present invention relates to monitoring aspects of debris flow disasters along railway lines. Background technique [0002] At present, the railway system is in a period of rapid construction and development. With the rapid expansion of the scale of the high-speed railway network, the level of technical equipment is also rapidly improved, and the speed and capacity are increased. At the same time, we must also realize that railway transportation safety is also facing more challenges and tests. The surrounding environment of the railway is more complicated, the natural climate environment changes frequently, and the disaster weather increases, which has an impact on the safety of railway transportation, especially the operation safety of high-speed railways.
