Description
Technical field
The utility model relates to underground concrete structure constuction joint and shrinkage joint waterproofing materials technical field, but particularly a kind of slip casting formula waterstop that has non retern valve, can repeat the slip casting pre-detection.
Background technology
In civil engineering, the conventional waterproof solution at the constuction joint of concrete structure and shrinkage joint is to adopt waterstop (metallic water stop band, steel limit waterstop, rubber fastening band, other plastics class waterstops etc.) to carry out waterproofing work, but because this class waterproofing materials is when construction, because the defect cause of construction quality and material self, the phenomenon of percolating water often takes place in underground concrete structure, and the later stage is repaired difficulty greatly, the expense height.
At present, on the market, begin to adopt the slip casting formula waterstop of band Grouting Pipe, promptly on traditional waterstop, increase 1-2 bar Grouting Pipe, on Grouting Pipe, be provided with slurry outlet or seam, if the waterproof quality of waterstop can not guarantee, can carry out the slip casting in later stage by slurry outlet on Grouting Pipe and the tube wall or seam and repair, improved the waterproof quality of waterstop.
As: the waterstop of the band Grouting Pipe of the patent No.: ZL03234343.4;
The patent No.: ZL03217222.2 external ejection for water plugging for building band;
The patent No.: ZL03217223.0 middle-set-type ejection for water plugging for building band.
The slip casting formula waterstop of this class band Grouting Pipe, be feasible theoretically, but, find in actual use, when the ejection for water plugging band being carried out slip casting and repair, slip casting effect is bad, and the waterproof quality of concrete structure construction seam or shrinkage joint (deformation joint) can not 100% guarantees, and Grouting Pipe can only be annotated slurries one time, can not repeatedly repeat slip casting and use.Its main cause is: 1. when fluid concrete, slurry outlet on the waterstop Grouting Pipe or sew concrete parcel, the cement screened stock penetrates into slurry outlet or seam the inside easily, cause slurry outlet or seam to stop up, 2. since Grouting Pipe on slurry outlet or the seam directly contact with concrete, slurry outlet or seam are not opened or open space, so cause slurry outlet or seam to open difficulty, pulp is not smooth.3. owing to there is not the non retern valve function, the slurries that injected flow backwards easily, influence slip casting effect.
Summary of the invention
The purpose of this utility model is to provide a kind of and has the non retern valve function, can repeat slip casting and can carry out the novel slurry filling formula plastics or the rubber fastening band of pre-detection, solved existing slip casting formula waterstop slurry outlet or seam is easily blocked, pulp is not smooth, the slip casting repair efficiency is bad, can not repeat the problem of slip casting and pre-detection etc.
In order to realize above purpose, the utility model provides a kind of slip casting formula waterstop, comprises the waterstop body, the damping tooth bar of both sides on the waterstop body, Grouting Pipe on the waterstop, the slurry outlet on the Grouting Pipe is characterized in that: the slurry outlet exit is provided with unidirectional non-return device.
Described unidirectional non-return device is bar or the cover that expanded material is made, and specifically can select bipeltate bar or bipeltate cover for use.
Wherein, unidirectional non-return device can adopt following structure: described slurry outlet exit is provided with groove, and the bipeltate bar is positioned at groove.Also can adopt another kind of structure: described bipeltate cover is placed in outside the Grouting Pipe tube wall, and bipeltate puts and is provided with stowing.
Preferably, this slip casting formula waterstop is provided with two Grouting Pipe.
Grouting Pipe can be positioned on the waterstop body, also can be positioned on the damping tooth bar.
1 to 4 row's slurry outlet is set on the tube wall of each Grouting Pipe along the longitudinal direction.
The sealing that is used for using at shrinkage joint (deformation joint) has centre bore, and the waterstop that is used for the constuction joint use does not then have centre bore.
The beneficial effects of the utility model are: slurry outlet be difficult for blocked, pulp is smooth, institute's injection slurry does not flow backwards, the slip casting repair efficiency is good, and can repeat slip casting and pre-detection.
