Abstract
The utility model provides a kind of water sealing structure at large-scale water delivery building expansion joint, including U-shaped waterstop, the U-shaped portion of the U-shaped waterstop is arranged in expansion joint, the both ends of U-shaped waterstop are arranged on building substrate, closed-cell foam plate is set in the expansion joint, steel plate is set above the both ends of U-shaped waterstop, and steel plate and U-shaped waterstop are bolted on building substrate.The structure in expansion joint by being arranged closed-cell foam plate, it can play a supporting role to U-shaped waterstop, simultaneously because closed-cell foam plate has certain elasticity, U-shaped waterstop can be made to be deformed upon in reasonable range, and closed-cell foam plate can also play certain waterproof action.In preferred scheme, the external coating epoxy resin mortar layer of building substrate and two end in contact of U-shaped waterstop, epoxy resin mortar layer has relatively high flatness, increases the leakproofness between U-shaped waterstop, and water-stagnating effect improves.
Description
Technical field
The utility model belongs to civil construction field, more particularly to a kind of water sealing structure at large-scale water delivery building expansion joint.
Background technology
The building bodies such as aqueduct, channel, pipeline, water-conveyance tunnel are that conveying ditch water flow crosses over rivers and canals, road, mountains and rivers, the mouth of a valley
Deng water carrying services, except for convey water in a canal carry out field irrigation, urban domestic water, industrial water, in addition to across basin water delivery, also
Can water supply and sewage and water conservancy diversion be used.Water conveyance structure is needed by structure construction, construction, climate change and other factors dictates at present
In aqueduct position appropriate, expansion joint is set.
The expansion joint water sealing structure of water conveyance structure large-scale over long distances generally with concrete pouring construction and circumferential direction is embedded in
Inside works, and to the dark culvert structure in extreme terrain position, although structural shape is roughly the same, if still using normal
Hermetic seal band is embedded in works by rule, can form infiltration because the part of hermetic seal is bonded with concrete not close
The sealing antiseep requirement of water conveyance structure cannot be effectively ensured in channel, and security risk protrudes when later stage water flowing is run.
Invention content
The technical problem to be solved by the utility model is to provide the water sealing structure that expansion joint is built in a kind of large-scale water delivery, energy
Enough sealing problems for solving large-scale water conveyance structure expansion joint, make hermetic seal firmly install, and closely tied with concrete surface
It closes, ensure that the sealing effect of antipriming, it is ensured that the safe operation of engineering construction being smoothed out with later stage engineering.
In order to solve the above technical problems, technical solution used by the utility model is:A kind of large size water delivery building is flexible
The U-shaped portion of the water sealing structure of seam, including U-shaped waterstop, the U-shaped waterstop is arranged in expansion joint, the both ends of U-shaped waterstop
It is arranged on building substrate, closed-cell foam plate is set in the expansion joint, steel plate, steel plate are set above the both ends of U-shaped waterstop
And U-shaped waterstop is bolted on building substrate.
In preferred scheme, the external coating epoxy resin mortar layer of the building substrate and two end in contact of U-shaped waterstop.
In further embodiment, fluid sealant is arranged in epoxy resin mortar layer upper surface.
In preferred scheme, blown rubber is set between the steel plate and U-shaped waterstop.
In preferred scheme, polyethylene foam sheet is set above the U-shaped portion of the U-shaped waterstop, is poured above U-shaped waterstop
Concrete layer is built, concrete layer is consolidated with polyethylene foam sheet.
In further embodiment, the polyethylene plate surface coats polysulfide sealant.
A kind of water sealing structure at large-scale water delivery building expansion joint provided by the utility model, has the advantages that：
1, closed-cell foam plate in expansion joint is set, can play a supporting role to U-shaped waterstop, simultaneously because closed-cell foam
Plate has certain elasticity, U-shaped waterstop can be made to be deformed upon in reasonable range, and closed-cell foam plate can also rise
To certain waterproof action.
2, the external coating epoxy resin mortar layer of two end in contact of building substrate and U-shaped waterstop, epoxy resin mortar layer, which has, to be compared
High flatness, increases the leakproofness between U-shaped waterstop, and water-stagnating effect improves.
3, polyethylene foam sheet is set above the U-shaped portion of U-shaped waterstop, U-shaped portion of the sundries to U-shaped waterstop can be prevented
Damage, while polyethylene foam sheet and the concrete layer that consolidates therewith constitute first of antiseepage barrier.
