Abstract

The invention relates to the field of construction and relates to the construction of curved water channels. The purpose of the invention is to increase the accuracy of the fabrication of the channel, the smoothness of its internal surface, resistance to mechanical and chemical effects of the medium passing through the channel, as well as reducing the cost of production. When implementing the method of constructing channels on the pads, segments 1, 2 of wood paneling are formed, first putting on the block protective layers of wooden paneling, on which a bearing layer of mesh concrete is then applied, simultaneously forming connecting flanges 9 and 10 and possibly edges. The protective layers and the carrier layer are firmly connected to each other. After removing the segments 1 and 2 from the pads, they are bolted and fixedly mounted on the base of the channel, the outlets are closed, and after the wooden paneling has been filled with concrete, the exit barriers are removed. 8 hp ff, 6 ill.

Claims (9)

Claim 1. A method of constructing channels in concrete structures, mainly curved water channels with non-expandable surfaces, including fixing the front elements into the body of a building under construction, characterized in that: environment, as well as reducing manufacturing costs, first produce a thin-walled channel from finished shell segments formed from armcoce on the one manufactured advantageously by the method of the ship blocks having a channel shape, is applied on the pad protective layer forming the inner surface of the channel which is resistant to mechanical and chemical attack passing through the pad, a layer of laminate, reinforced with glass fibers, constituting the forming surface pads. 2. The method of pop. 1, characterized in that directly on the surface in that after opening the channel exits, a paint coating is applied to its inner surface. 3. The method according to π. 1, from l and h a y u 4. The method of pop. 1, characterized in that after the installation of shell segments 15 tons of heavy ballast is introduced into the channel, which is removed after concrete is poured onto the outer surface of the channel. 5. The method of pop. 1, characterized by a medium channel onto which a carrier layer of reinforced cement is then applied, at the same time forming in it connecting longitudinal and end flanges with holes for connecting bolts, as well as possibly reinforcing ribs, both of these layers firmly gripping, then after removing - 25 tons of shell segments made of reinforced cement from blocks after the required maturing period of concrete has expired with connecting bolts, they tighten their connecting flanges and are mounted motionless on a concrete base, then they close the outlet openings of the channel ala, and as far as possible establish supports within it, then the channel is poured outside with a layer of concrete of the required thickness. 35 5 in that during the laying process on the protective layer of the carrier layer of reinforced cement, part of the reinforcing rods of the reinforced cement are brought out of the shell segments, and during their installation on the concrete base 10, the removed rods are welded with the rods previously concreted into the base. 6. The method according to p. 1, characterized in that the protective layer of the channel is made of repeating shaped parts with anchor protrusions on the inside. 7. The method according to p. 1, characterized in that as a protective layer using a layer of resin chemical curing with fiberglass, in which during the curing partly enter the reinforcing anchor mesh. 8. The method of pop. 6 ,. characterized in that the shaped parts are ceramic. 9. The method according to p. 6, characterized in that the shaped parts are made of plastic. Figure 1 FIG. 3 Ί Fig 5
