The sandbag is packed sandstone, which is equipped with suspension hook.
Compared with prior art, the utility model major design is a kind of for protecting the dress of tunnel excavation Blasting shock wave
It sets, which is mounted at the arch ring of tunnel portal, and structure includes rubber slab, steel plate, bolt, railing and sandbag etc.,
And rubber slab be equipped with it is a plurality of, every slat gum plate, which is hung from above, to be mounted between arch ring vault and ground, and top with arch ring carry out
Fixed, lower part is pushed down by sandbag, and adjacent rubber slab partly overlaps between each other, so as to form tunnel excavation is completely covered by
The spring protective structure of section, and the shock wave that Excavation blasting generates in spring protective structure energy tunneling boring shielding tunnel
And slungshot.This protective device has many advantages, such as simple structure, operation convenience, cost savings, safe and reliable, and cooperation is corresponding
Operating method also has the handling characteristics such as recycling, energy conservation and environmental protection, therefore can ensure that engineering construction safety, reduces noise pollution,
Economic benefit and social benefit are significant.
Detailed description of the invention
Fig. 1 is the structural facades schematic diagram of the utility model.
Fig. 2 is the I-I sectional view of Fig. 1.
Specific embodiment
It will elaborate again by above-mentioned attached drawing to the utility model embodiment below.
As shown in Figure 1 and Figure 2,1. ground, 11. explosion faces, 2. arch rings, 3. vault slopes, 4. railings, 5. rubber slabs, 51. weights
Folded portion, 52. bundling belts, 6. steel plates, 7. bolts, 8. sandbags, 81. suspension hooks.
Tunnel excavation Blasting shock wave protective device and operating method as shown in Figure 1 and Figure 2 are mainly used for that tunnel is protected to open
The shock wave and slungshot generated when explosion by explosion face 11 is dug, which is mounted at the arch ring 2 of tunnel portal, comes with this
Guarantee the safety of tunnel excavation blast working, and avoids the noise pollution on periphery.
The protective device includes a plurality of rubber slab 5 for hanging from above and being mounted between 2 vault of arch ring and ground 1, the rubber
Plate is flexible material production, is only b without bearing torque, every width by pulling force, length by position vault and ground
The height in face 1 determines, is located at the vault center of arch ring 5 as longest rubber slab, cover 2 top lower edge of arch ring and ground 1 it
Between computational length be L, and the total length of every slat gum plate 5 also needs to push down length plus vault anchorage length and ground sandbag 8；
Remaining rubber slab 5 is successively symmetrical arranged centered on longest rubber slab, and along 2 two sides of arch ring, length be arch ring at the top of lower edge with
Height between ground pushes down length plus vault anchorage length and ground sandbag 8, and a plurality of rubber slab 5 is by Blasting shock wave
