The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.After the content of having read the utility model instruction, those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's scope required for protection equally.
The chimney pore space structure is three layer construction as shown in Figure 1, i.e. barrel 1, insulation layer 2 and liner 3, and insulation layer generally adopts between pearlite heat-insulation plate and the outer tube wall and has the slit.After the sampling of reinforced concrete chimney tube wall opening, need renovation reinforced between barrel external surface 4 and the barrel inner surface 5.
Outside renovation reinforced device after the reinforced concrete chimney tube wall opening sampling of the present utility model, whole device as shown in Figure 2.This device is comprised of inner seal plate 11, filling device and external seals plate 12 3 parts, inner seal plate 11 is used for sealing barrel inner surface 4, filling device comprises the cylinder-shaped body of both ends open, grouting mouth 13 is set in the side of cylinder-shaped body, by filling device grouting material is injected barrel, external seals plate 12 is used for sealing barrel external surface 5.
The structure of inner seal plate 11 as shown in Figure 3, inner seal plate 11 is quality of rubber materials, the embedded steel plate of middle flat area, namely edge 17 is simple elastomeric material, zone line 18 embedded steel plates.Be unidirectional propelling design, integral body is arc.Forward advances freely, during negative drawing, relies on arc tension force to stop and advances.
