Detailed Description
The invention will be further described in detail with reference to the drawings and the following detailed description, which are provided for the purpose of clearly understanding the invention and are not intended to limit the invention.
As shown in the figure, the utility model mainly comprises three parts, namely a vertical rod 1, a flexible protective net 2 and an elastic metal protective net 3.
Wherein the upright stanchion 1 is a vertical metal tube. A row of metal side hooks 4 are welded on the side face of the vertical rod 1 and used for hanging the flexible protective net 2. The top surface of the upright stanchion 1 is welded with a top ring 5 for binding a stay cable 6. The vertical rod 1 is straightened by two stay cables 6, so that the stability of the vertical rod 1 and the flexible protective net 2 is ensured. The stay cable 6 is fixed on the ground by an anchor 7.
The flexible protective net 2 is a whole piece of nylon rope net, the size of the grid is large, and the flexible protective net is mainly used for absorbing impact energy of blasting flyrock. The length of the flexible protective net 2 is equal to the erection distance of the vertical rods, and the width of the flexible protective net 2 is equal to the height of the vertical rods. The flexible protective net is hung on the vertical rod through the side hook 4 of the vertical rod to form a hanging protective net.
The metal protection net 3 is a plurality of assembled metal nets, has small grid size and is mainly used for intercepting blasting flystones. A row of hooks 8 are arranged at the upper part of the metal net 3 and hung on the flexible protective net 2 through the hooks 8. A plurality of metal nets 3 are spliced together to form an integral metal net.
The utility model discloses an use steps as follows:
(1) a plurality of vertical rods 1 are erected in the vicinity of a building 10 to be protected and face the blasting flyrock throwing direction. The distance between the vertical rods 1 is 10m, the height is 8m, and a flexible protective net is hung between every two vertical rods.
