The device of complex sealing and protection of expansion joints of hydraulic structures from sprouting by arboreal and shrubby vegetation

摘要

The utility model refers to the field of hydraulic engineering construction and is intended for sealing and protecting expansion joints in reinforced concrete slabs of channel linings.;A device for complex sealing of expansion joints in reinforced concrete slabs containing a joint cavity of a seam of an elastoplastic material made in the form of a double-folded sheet in a U-shaped form, characterized in that the elastoplastic material is polypropylene with an inner layer of glass fiber reinforcement having a deformation compensator of polyurethane foam , and all along the U-shaped aggregate has locking wings and a T-shaped fold doubling the deformation seam. To completely exclude filtration losses, a sealant or mastic or epoxy resin layer is applied to the U-shaped aggregate prior to installation in the expansion joint. The technical result is the reliability and environmental friendliness of the construction material, the ease of installation, the reduction of water losses for filtration, impossibility of germination of tree and shrub vegetation and increase in the durability of the work of structures. 1 z.s. f-ly, 2 ill.
