Background technology
On the concrete component of hydraulic structures such as power station, canal for water conveyance, tunnel and aqueduct, have seam usually; After long-term the use; Crack in various degree can appear on the concrete component; Particularly at northern extremely frigid zones, owing to will experience ice period every year, the phenomenon that strain cracking appears in concrete component is more extensive.Answer the processing method of butt joint and crack phenomenon normally its slit surfaces to be sealed processing with seal plate, gum filler or encapsulant etc.; But because seam and crack all are to be in the dynamic real-time change usually; After use after a while, closed material generation deterioration can't adapt to the needs in the crack that is in real-time state of development in real time; Therefore make that the sealing intractability is higher, this also is a technical barrier that all the time perplexs the water conservancy project field.
Summary of the invention
The utility model is accomplished in order to solve deficiency of the prior art, the purpose of the utility model provide a kind of simple in structure, can permanently effective impervious sealing and the in real time big aperture that adapts to the crack change seam or the water-stopping structure in crack of the novel hydraulic concrete buildings of needs.
The technical scheme of the utility model is:
A kind of seam of novel hydraulic concrete buildings or the water-stopping structure in crack is characterized in that: be included in surface of concrete structure, cross over the sealing cover plate that said seam or crack be provided with and be arranged on the said sealing cover plate and cover the sealing film of said sealing cover plate; Said sealing film contacts with the crimping of said sealing cover plate, said sealing film and said surface of concrete structure adhering and sealing.
Further, said sealing cover plate and said surface of concrete structure pass through gluing layer adhering and sealing between the two.
Said sealing film and said surface of concrete structure pass through gluing layer adhering and sealing between the two.
Said sealing film is bonding or not bonding the contact with said sealing cover plate.
Distance between the periphery of said sealing cover plate to the periphery of said sealing film is greater than 0.5cm.
Said sealing cover plate is put along sewing cloth of seam or crack, is covered on seam or the crack, and the distance at all back gauge seams of said sealing cover plate or the edge in crack is greater than 0.5cm, and the width of said sealing cover plate is greater than 1.0cm.
Said sealing film solidifies after applying for liquid polyurea materials and gets.
The thickness of said sealing cover plate is greater than 0.3cm; Said sealing cover plate is that polyolefin timber lipid or polyvinyl chloride or rubber type of material are processed.
The water-stopping structure of the utility model can guarantee the durability of the sealing in seam and crack; Sealing film with high degree of flexibility can be realized the adaptivity adjustment; Through the tension deformation of repeated multiple times, the real-time extension of following the tracks of all directions in seam and crack changes, and can not tear; When the function that guarantees coat film realizes sealing, have again that abrasion resistance is strong, the life-span long, adaptable advantage.

Figure number explanation: 1... concrete component 2... seam or crack 3... sealing cover plate 4... sealing film 5... sealing groove
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
As shown in Figure 1; The seam of a kind of novel hydraulic concrete buildings of the utility model or the water-stopping structure in crack, be included in concrete component 1 the surface, cross over the sealing cover plate 3 that seam or crack 2 be provided with and be arranged on the sealing cover plate and cover the sealing film 4 of sealing cover plate.The tight sealing cover plate of the sealing mould of the utility model.
The sealing cover plate of the utility model can be that crimping contacts with surface of concrete structure, also can be through gluing layer (not shown) adhering and sealing between the two.
The sealing film of the utility model can be that crimping contacts with the sealing cover plate, also can be through the bonding contact of gluing layer.
The sealing film of the utility model should adopt liquid polyurea materials after applying, to solidify and get sealing film after the curing and surface of concrete structure adhering and sealing.
For the enhanced leaktightness effect, sealing film of the utility model and the preferred adhering and sealing of surface of concrete structure promptly increase the gluing layer between the two, make sealing film and surface of concrete structure pass through gluing layer (not shown) adhering and sealing between the two.
The size of the sealing cover plate of the utility model is advisable with covering joints or crack, and the distance between the periphery of edge to the sealing cover plate in preferred seam or crack is greater than 0.5cm, to guarantee outstanding sealing coverage effect.
The used material of sealing cover plate of the utility model be preferably have flexibility, the material of low elastic modulus, big ductility; When concrete seam or fracture open, can follow the tracks of distortion, automatic filling crack, be preferably polyolefin timber lipid or polyvinyl chloride or rubber type of material and process.
The sealing cover plate of the utility model is preferably and on polyolefin timber lipid diaphragm, laminates nonwoven or cloth forms, and to strengthen its intensity, is easy to operation, and can guarantees good gas permeability.
The thickness of sealing cover plate and width need possible the Breadth Maximum according to seam or crack, the hydraulic pressure that cover plate position institute will bear etc. definite through calculating, and the thickness of ordinary circumstance cover plate is not less than 0.3cm, width is not less than 1.0cm.
