Abstract
The utility model relates to a grouting water stop tube of expansion water stop type. The utility model comprises a body of the water stop tube, one or several expansion rubber strip and silk screen. The preceding body of the water stop tube comprises a plurality of slurry outlet holes and one or more water-expandable rubber strip. The surface of the body of the water stop tube is placed with the expansion rubber strip and water-expandable water stop strip. The utility model has the active water stop function of the traditional water-expandable water stop strip and the advantage of grouting tube. Thus, the utility model can carry out water proof quality pretest as well as grouting reparation. Provided that the water-expandable stop strip on the grouting water strop tube fails to stop the water and the leakage occurs continuously, the grouting water stop tube can complete grouting reparation by the slurry outlet hole. Compared with the current grouting tubes in the market, the present grouting tube of water-expandable type bears lower manufacturing cost. If the water-expandable water stop strip on the tube body succeeds in stopping the water, the cost of grouting reparation could be saved subsequently.
Description
Technical field
The utility model relates to a kind of novel ejection for water plugging pipe, belongs to the slit waterproofing materials technical field between concrete construction joint, slit, concrete ater-casting and the connection of New-old concrete structure.
Background technology
At present, in all concrete underground structures, for example: in the underground constructions such as dam, reservoir, tunnel, culvert, subway, basement, underground building, when its concreting, must leave constuction joint by certain length (being generally about 8-15 rice) of building, carry out compartment or jump the storehouse fluid concrete, to prevent that concrete various crack (the especially temperature of concrete and shrinkage crack) from taking place and assurance Concrete Construction quality.But, the waterproof of concrete construction joint in the underground construction, because of reasons such as the difficulty of waterproofing materials, construction quality, construction location and environment, leakage problem then appears easily, especially the waterproof at position between the connection between the old and new's concrete structure and concrete wall and base plate, difficult more, its consequence has influence on the application life of concrete structure.The prior art scheme solves this type of problem, mostly adopt pre-buried waterstop at Concrete Construction seam place, traditional forms such as hydro-expansive rubber bar, but, if waterstop and hydro-expansive rubber bar do not reach requirement because of the quality of material own or construction quality, thereby cause constuction joint the situation of percolating water to occur, then need it is carried out scene punching and slip casting repairing, the difficulty of its repairing and expense are quite big, and the constuction joint waterproof quality instability after repairing, usually can not reach waterproof requirement, infiltration may repeatedly be recurred, and has had a strong impact on underground construction operation and application life, is a hard nut to crack always.
At present, the method of pre-buried ejection for water plugging pipe is adopted in beginning on the market in positions such as underground engineering construction seams, this traditional ejection for water plugging pipe can carry out later stage slip casting and repair (not needing on-the-spot boring), good water-proof effect and waterproof quality stability and no relapse after the constuction joint infiltration, but its weakness is after constuction joint seeps water, initiatively sealing as just a supplementary means of being convenient to repair, also must be repaired in slip casting, by the antiseepage of chemical grout ability sealing, and the expense height.
Summary of the invention
The utility model provides a kind of brand-new ejection for water plugging pipe, the advantage of the advantage of traditional Grouting Pipe and traditional water-swellable sealing rod is combined, the pre-detection and the slip casting mending function that promptly have traditional Grouting Pipe, has simultaneously the initiatively function of sealing of water-swellable sealing rod again, thereby the waterproof safety coefficient at other positions such as all constuction joints of underground construction of improving, and reduced the seepage chance, reduced the later stage renewal expense.
For achieving the above object, the utility model by the following technical solutions:
A kind of expansion water stopping type ejection for water plugging pipe, comprise antipriming pipe body, silk screen, be located at one or more water-swellable sealing rod of described antipriming pipe outer surface of tube body, described antipriming pipe body is provided with a plurality of slurry outlets, and described silk screen is located at described water-swellable sealing rod external surface.
As a kind of improvement of the present utility model, also comprise one or more bipeltate bar of being located at described antipriming pipe outer surface of tube body, described silk screen is located at described bipeltate bar and water-swellable sealing rod external surface.
As a kind of improvement of the present utility model, described antipriming pipe outer surface of tube body is provided with the multiple tracks longitudinal fluting, and described slurry outlet is located in the described groove, and described bipeltate bar, described water-swellable sealing rod is all or part of is located in the described groove.
As another improvement of the present utility model, described bipeltate bar and water-swellable sealing rod are spaced.
One improve as of the present utility model, the cross section of being located at the described bipeltate bar in the groove is for circular, and the cross section of its this groove that is complementary is for semicircle again.
One improve as of the present utility model, the cross section of being located at the described water-swellable sealing rod in the groove is fan-shaped again, and the cross section of this groove that is complementary with it is fan-shaped.
As a kind of optimal way of the present utility model, described ejection for water plugging pipe external diameter is 12～38mm, and the interior diameter of described antipriming pipe body is 4～20mm, and the diameter of described slurry outlet is 2～6mm.
As another optimal way of the present utility model, the quantity of described bipeltate bar is 2 to 6; The quantity of described water-swellable sealing rod is 2 to 6.
As an optimal way more of the present utility model, the quantity of described bipeltate bar is 3; 3 of the quantity of described water-swellable sealing rod, the quantity of described groove are 6 roads, and groove 60 degree is at interval arranged.
The expansion water stopping type ejection for water plugging pipe that adopts technical solutions of the utility model to make, owing on ejection for water plugging pipe body, be provided with the water-swellable sealing rod, make the ejection for water plugging pipe have multiple function, has multiple tracks waterproof safeguard, improved the waterproof safety coefficient, reduce the waterproof cost, the function that promptly 1. has the active sealing of conventional water-swellable sealing rod, when there is infiltration at positions such as constuction joint, the water-swellable sealing rod begins to expand gradually and plays sealing antiseepage effect, if the sealing success can have been saved the expense that follow-up slip casting is repaired; 2. the advantage that has Grouting Pipe, can carry out the waterproof quality pre-detection to positions such as constuction joints and can carry out the slip casting repairing again, if the failure of the water-swellable sealing rod sealing on the ejection for water plugging pipe, continue to have infiltration to take place, can carry out slip casting by the slurry outlet on the body and repair, good water-proof effect and not recurring; 3. compare with existing Grouting Pipe on the market, this expansion water stopping type Grouting Pipe comprehensive cost is low, because if the success of the water-swellable sealing rod sealing on the body can be saved the expense that later slip casting is repaired.
