Abstract
An expansion joint or crack water resistance and seepage control structure for a hydraulic concrete member is characterized in that the structure comprises a support part (7) arranged at the top of the expansion joint or crack of the hydraulic concrete member; the periphery of the support part (7) is covered with a sealed filled layer (3); and a protective layer (4) is arranged on the periphery of the sealed filled layer (3). The structure can adapt to various complex joint interfaces, has an ideal sealing effect, and avoids the connector existence, so that the water pressure resistance of the whole seepage control structure is improved, and the capacity adapting to the seams variation is enhanced.
Description
Technical field
The utility model relates to a kind of concrete for hydraulic structure member sealing leakage preventing structure, relates in particular to a kind of structure of utilizing flexible caulking material and field-applied filmogen to be used in combination the sealing antiseepage.
Background technology
Usually can be provided with the shrinkage joint or the crack occur on the concrete component of hydraulic structures such as power station, canal for water conveyance, water-conveyance tunnel and water delivery aqueduct.Sealing to these seams is handled, and wants the sealing good seepage-proof property on the one hand, can bear the water pressure of respective degrees; On the other hand, because shrinkage joint and crack seam width are in dynamic change state, must make enclosed construction can adapt to its distortion.Therefore, the processing of concrete for hydraulic structure member expansion joint or crack sealing is technological difficulties in water conservancy project field always; When existing tens meters even up to a hundred meters head pressures to do the time spent, it is particularly outstanding that this difficult point becomes.
The measure commonly used that addresses this problem both at home and abroad is to utilize band steel and bolt that rubber tile is striden the stubborn sealing both sides that are pressed in of seam.The validity of this measure depends on the planeness of surface of concrete structure.Usually the surface finish of the concrete for hydraulic structure member of large volume pouring be cannot say for sure to demonstrate,prove, and the sealing ability of prefabricated profiled rubber tile is limited; Changeable when the sealing complications, when being nonplanar spatial shape, it is clumsy invalid that this measure shows especially.
To sum up, in order to solve the deficiencies in the prior art part, the utility model proposes a kind of improved concrete for hydraulic structure member expansion joint or crack sealing leakage preventing structure.
Summary of the invention
The utility model provides the structure of a kind of concrete for hydraulic structure member expansion joint or crack sealing antiseepage; described structure comprises the support member that is arranged at described concrete for hydraulic structure member expansion joint or top, crack; described support member periphery coats the sealing packed layer, and described sealing packed layer periphery is provided with topping.The sealing packed layer is flexible caulking material, and overcoat is the flexible film material of in-place forming.Described on-the-spot filmogen is flowable liquid state before coating, is coated in body surface and becomes after a period of time flexible solid film is arranged.Described on-the-spot filmogen is the polyureas series material.Be added with pliable and tough fiber in the described on-the-spot filmogen and/or cloth strengthens its intensity.Between filmogen and component surface, there is cementitious materials to guarantee that both are bonding closely.Described pliable and tough support bar is rubber bar and/or sticking plaster.
The concrete advantage of the utility model is as follows:
1. by applying on-the-spot filmogen, substitute prefabricated panels is installed as overcoat.Apply film forming and can pass through multiple measure realization such as in-situ spraying, blade coating or brushing.This structure can adapt to various complicated seam faces, the sealing effectiveness ideal, and do not have the joint problem.
2. between filmogen and component surface, seal with flexible caulking material opposite joint face earlier.Flexible caulking material can support to membrane material; The existence of flexible caulking material makes protecting film in the direction perpendicular to sealing simultaneously, and bigger extensibility is arranged.This measure had both improved the hydraulic pressure resistance ability of whole leakage preventing structure, increased it again and adapted to the ability that sealing changes.
3. on-the-spot filmogen strengthens its intensity by adding pliable and tough fiber and/or cloth, can further improve the hydraulic pressure resistance ability and the external force resistance damage capability of whole leakage preventing structure.
4. be stuck in sealing with pliable and tough bars such as rubber bar and/or sticking plasters as support component, can limit flexible caulking material under the high hydraulic pressure effect, in the seam chamber, flow, further improve the hydraulic pressure resistance ability and the external force resistance damage capability of whole leakage preventing structure.

The specific embodiment
The structure of a kind of concrete for hydraulic structure member expansion joint or crack sealing antiseepage; described structure comprises the support member that is arranged at described concrete for hydraulic structure member expansion joint or top, crack; described support member periphery coats the sealing packed layer, and described sealing packed layer periphery is provided with topping.The sealing packed layer is flexible caulking material, and overcoat is the flexible film material of in-place forming.Described on-the-spot filmogen is flowable liquid state before coating, is coated in body surface and becomes after a period of time flexible solid film is arranged.Described on-the-spot filmogen is the polyureas series material.Be added with pliable and tough fiber in the described on-the-spot filmogen and/or cloth strengthens its intensity.Between filmogen and component surface, there is cementitious materials to guarantee that both are bonding closely.Described pliable and tough support bar is rubber bar and/or sticking plaster.
As shown in Figure 1, on concrete component 1, place on the seam face 2 as support component with pliable and tough rubber bar and/or sticking plaster 7 earlier, seal with 3 pairs of concrete component 1 shrinkage joint of flexible caulking material or 2 surfaces, crack, the component surface at caulking material and seam both sides certain width applies the on-the-spot material 4 of flexible film that forms as overcoat then again.On-the-spot filmogen 4 is by adding pliable and tough fiber and/or cloth 5 strengthens its intensity.Between filmogen 4 and component surface, utilize cementitious materials 6 to guarantee that both are bonding closely.
