Title:
CONDUIT REPAIR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2008/075406
Kind Code:
A1
Abstract:
A conduit repair structure in which solid objects are less likely to accumulate
on a conduit bottom and that, even if solid objects accumulates on the conduit
bottom, facilitates removal of the solid objects. A hollow frame-like reinforcement
body laid substantially along a cross-sectional shape of a conduit (1) is constructed
using a reinforcement member (2) having fitting sections (2p) arranged at predetermined
intervals on the inner side of the conduit (2). Resin inner face members (10)
are attached to the inner side of the reinforcement body, and an indurative filling
material is placed in the space formed by the inner face members (10) and a conduit
inner wall (1a) to form a filling material layer (3). A body section (10c) of each
inner face member (10) is formed recessed in its width direction. The recessed
shape of the body sections (10c) forms riblets on the bottom of the conduit, and
this reduces resistance to water flowing in the conduit. Even in conduits, such
as a horseshoe-shaped conduit and a rectangular conduit (box culvert), having
flat bottoms and in which objects flow at low speed, the structure allows the objects
to flow easier.
