PL400448A1 - Explosionproof insulation dam - Google Patents

Abstract

The explosion-proof insulation dam is characterized by the fact that the external structure of the dam conclusion (1), (2) is a flat, spatial flexible structural system made of flaccid material, the shape of the external contour and dimensions of which are similar to the shape and dimensions of the cross-section of a pavement heading flexible front wall (1a), flexible rear wall (1b) connected by a peripheral side wall (1c). At the same time, the walls (1a) and (1b) are grafted with each other with reinforcing tendons, creating a flat elastic structural structure with an internal space filled with quick-setting adhesive, which is attached to the neighboring hatches of the pavement housing (7) with hook holders (1h). In turn, the connection point of the flexible walls (1a) and (1b) with the peripheral side wall (1c) is the edge of the connection between the structural system of the dam conclusion (1, 2) and the tire sealing sleeve (1i). In addition, in the internal space between the conclusion (1) and the conclusion (2) it is at least through several fastening strands (4) flooded with a quick-setting adhesive forming the basic construction of a dam stopper. Technological holes are made in the walls (1a) and (1b) of the conclusion (1) and conclusion (2).
