In the first stage, the migration volume of each slip layer of the source is recorded by the movement of the slip layer frame 140, which is the initial migration volume of the slip layer. And in the second stage, when the migration amount of the sliding layer exceeds the monitoring range of the sliding layer frame 140, the lower wedge block 340 moves towards the upper wedge block 350 and contacts with the upper wedge block, the thrust of the sliding layer is decomposed into horizontal thrust and upward jacking force by a wedge surface, under the limiting action of the arc rail frame 320, the whole buried cage frame 120 is turned over towards the ground surface, the sliding layer continuously migrates to bury the foundation pit, one side of the buried cage frame 120 is lifted until the hydrophobic blocking frame 330 stands in the sliding direction of the side slope, the transformation of the blocking dam is completed, the large-scale earth surface debris flow is ready to be blocked, meanwhile, part of monitoring devices are protected, the type and the scale of the source of the river course evolution in the earthquake region are accurately monitored, and the research and the analysis of the river course evolution in the earthquake region are facilitated.
In the third stage, the sliding layer is migrated and broken to cause the generation of the earth surface debris flow, the hydrophobic blocking frame 330 is matched with the blocking frame 510 and the blocking plate 511 to block the earth surface debris flow, the debris flow impacts the top pressure plate 732 to drive the induction column 530 to slide and impact the pressure sensor 550, the height of the debris flow at the moment is recorded, and the induction column 530 is reset through the reset spring 540. The hydrophobic diversion effect of the hydrophobic barrier 330 and the narrow and wide design of the interception plate 511 can reduce the blockage of debris flow in front of the interception device. The circulation time and the circulation height of the earth surface debris flow are accurately recorded, the scale of the debris flow is measured and calculated, and the law of the erosion of the debris flow to the river channel evolution by different source type proportions is accurately researched by matching with the type proportion of the sliding layer source.
The mud-rock flow that the short-term heavy rainfall triggered can corrode the evolution to the earthquake district river course, collects local rainfall through rain collecting bucket 710, through rainfall flowmeter 720 accurate record rainfall. Collect the infiltration in the mud-rock flow through side flow head 730, through the infiltration water content of each height of saturation flowmeter 740 accurate record mud-rock flow, cooperate above-mentioned structure, research rainfall, the relation between the loose degree of earthquake side slope thing source, the kind and the proportion of skid bed thing source and the scale of landslide mud-rock flow, carry out scientific data to current earthquake area river course evolution and corrode, the convenient research and the analysis to earthquake area river course evolution.
It should be noted that the specific model specifications of the counter 145, the pressure sensor 550, the rainfall flowmeter 720 and the saturation flowmeter 740 need to be determined by type selection according to the actual specification of the device, and the specific type selection calculation method adopts the prior art, so detailed description is omitted.
