Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

1 to 2, the entire debris of the building (1) is covered with a debris screening network 10, the screening network 10 is a lightweight but very tough material in the form of a net weaving the building (1) It is a configuration that can effectively block the debris scattered during the explosion.

The outside of the debris blocking network 10 is covered with a blocking film 11, the blocking film 11 is composed of a fabric woven tightly light and very tough material to serve as a filter that air is distributed and dust is filtered It is supposed to be. Therefore, the dust can be trapped inside the blocking film 11 during the blasting of the building (1).

On the other hand, the blocking network 10 and the blocking film 11 is supported by the support (2) mounted on the roof of the building (1) stably supported by a predetermined height spaced apart from the top of the building (1), The barrier net 10 and the barrier film 11 may be directly covered on the outside of the building 1 without using the support 2.

One side of the suction pipe 32 is connected to the lower portion of the dust blocking membrane 11, and the other side of the suction pipe 32 is connected to the dust storage container 31 in which the filter 31a is embedded and the suction pump 30. .

Therefore, since the strong suction force generated in the suction pump 30 is transmitted to the suction pipe 32 through the reservoir 31, dust trapped inside the blocking membrane 11 is introduced into the reservoir 31 through the suction tube 32. Dust is filtered by the filter 31a and remains in the reservoir 31, and only clean air is discharged into the atmosphere through the outlet of the suction pump 30.

The suction pump 30 is provided in plurality in the lower portion of the blocking film 11, the number of which can be appropriately adjusted according to the size of the building (1) The present invention is limited to the number of the suction pump (30) no.

The blocking network 10 is fixed by a fixed pile 20 that is embedded in the ground along the lower periphery. The lower portion of the barrier film 11 is fixed to the floor by laying the barrier film around the T or L-shaped steel 20a so as not to enter the outside air.

One side of the elastic ropes 21 is fixed to the lower portion of the blocking film 11, and the other side thereof is fixed to the bottom by the fixing pile 20, so that the elastic rope 21 can elastically support the blocking film 11. It is.

In the present invention, a plurality of air temporary opening and closing holes 40 are installed on the blocking film 11 to prevent damage to the structure during instantaneous air expansion to prevent damage to the membrane material and deformation of the blocking film according to the expansion air pressure. Configured to prevent.

FIG. 3A is an exemplary view of a side opening and closing opening of the air temporary opening and closing 40. A portion of the blocking film 11 is cut to form a window 42c, and a cover 42a is formed to cover the window 42c. The lower end of 42a is attached to the support rod 42b having a predetermined weight.
