Detailed description of the invention
Fig. 1 is the utility model perspective view；
Fig. 2 is the utility model baffle detail drawing；
Fig. 3 use state diagram；
In figure, 1- pedestal；2- connecting shaft；3- baffle；4- bolt；The tunnel 5-；6- explosion wave.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figs. 1-2, spoiler described in the utility model is mainly made of parts such as pedestal 1, baffle 3, connecting shafts 2,
Pedestal 1 is fixed on 5 wall surface of tunnel by several bolts 4, and undertakes baffle 3 and power that connecting shaft 2 transmits；Connecting shaft
2 for connecting pedestal 1 and baffle 3；Baffle 3 plays decaying explosion wave and propagates for undertaking explosion wave load
Purpose, baffle 3 can rotate around connecting shaft 2.
When it is implemented, explosion wave load suffered by baffle 3 passes to pedestal 1 by connecting shaft 2, and then transmit
Tunnel wall surface is given, the load that baffle bottom end is born is greater than top；To enhance the reliability that load conducts, the baffle 3 is wedge shaped
