Description
Technical field
The utility model relates to the water conservancy project building field in civil engineering, and it is a kind of sticky pressure type aqueduct water-stopping structure in particular.
Background technology
Aqueduct is the common a kind of conveyance structure of hydraulic engineering circle, and its water-stopping structure is important detail structure, and difficulty of design and construction is large, and inefficacy ratio is high, and water-stopping structure decides the success or failure of aqueduct project.Buried during current domestic large-sized aqueduct engineering water-stopping structure mainly contains, bonded type and presser type, but there is following problem:
In buried water-stopping structure, directly rubber fastening band is cast in concrete, concrete below the waterstop of this kind of form is difficult to vibration compacting, the concrete binding site of waterstop and bottom is caused easily to produce defect, affect stagnant water effect, simultaneously once waterstop damages just cannot repair replacing, and be only limitted to cast in place process construction.
Bonded type water-stopping structure, directly utilizes epoxy mortar to be bonded on structural concrete by waterstop, and stagnant water effect depends on the effect of bonding and the quality of concrete surface.Because water-stopping structure is positioned at aqueduct expansion joints position, seam is seam of living.Under temperature action, water-stopping structure can be subject to back and forth stretching or compression, and effect not easily ensures, and it is high to there is basal plane processing requirements, is difficult to the problem met design requirement.
Presser type water-stopping structure, adopt pre-embedded bolt and keeper plate of steel to fix waterstop, stagnant water effect is by the planeness of fastening basal plane and the restriction of fastening force, and the precision of pre-embedded bolt is also wayward, and stagnant water effect is also undesirable.
Retrieve the Chinese utility model patent that publication number is 202482827U, described replaceable aqueduct deformation joint water-stopping structure, comprise the rubber fastening band main body being longitudinally provided with U-shaped structure, be respectively provided with row's stone bolt sealing retention mechanism in the both sides of the U-shaped structure of rubber fastening band main body.This kind of water-stopping structure bolt needs pre-buried, and positioning precision is wayward, and by the planeness of fastening basal plane and the restriction of fastening force, waterstop is changed in inconvenience; This water-stopping structure is often pressed leakiness by convex-concave compressing structure between top board and lower platen extruding closed-cell foam plate and waterstop or is fitted after having pressed bad, easily directly causes infiltration.
Summary of the invention
The purpose of this utility model is to provide a kind of sticky pressure type aqueduct water-stopping structure, changes the sealing principle of traditional water-stopping structure, provides a kind of waterstop and contact water-stopping structure closely bottom water stopping trough, ensure stagnant water effect, reduce rate of conveyance loss.The utility model weakens conventional adhesive formula or presser type water-stopping structure to the high request of concrete surface; Solve the uppity problem of traditional water-stopping structure bolt embedment precision, and fastening force is secure; Facilitate later period maintenance and replacing.
The purpose of this utility model is reached by following measure: sticky pressure type aqueduct water-stopping structure, comprise rubber fastening band, rubber fastening band there is U-shaped structure, the top of the upstream face of rubber fastening band seals with acrylamide sand grout block, the upstream face of the both sides of described U-shaped structure there is channel-section steel pressing plate, the back side of the both sides of described U-shaped structure there is pedestal, be bolted in pedestal, bolt does not penetrate base bottom, prevent the concrete mortar at the bottom of water stopping trough from infiltrating blocking bolt hole, be convenient to later stage replacing rubber fastening band and bolt.
In technique scheme, described back side there is epoxy adhesive layer.
In technique scheme, in described U-shaped structure, there is Bituminous hemp fiber, above U-shaped structure, in the middle of acrylamide sand grout block, have polysulfide sealant.
In technique scheme, described rubber fastening band is natural rubber waterstop, and described pedestal is stainless steel pedestal, and described bolt is stainless steel bolt, and described channel-section steel pressing plate is galvanizing bath keeper plate of steel.
The utility model is compared to prior art, and the dilatation of better commensurate structure parting, ensure that the normal work of analysis on aqueduct structure and waterstop; Make the stagnant water effect at aqueduct expansion joints place better, thus reduce water conveyance loss; Due to the close contact of rubber fastening band and pedestal, weaken the high request to concrete surface, not by the planeness of concrete surface and the restriction of fastening force, change the feature that existing water-stopping structure is high to construction technical requirement; Without the need to pre-embedded bolt, construction quality is controlled, convenient in later period maintenance and replacing.
