Abstract
The utility model discloses a seepage prevention structure for concrete structure seam prefabricated or cast -in -placely have than the wide recess of structural joint seam in water side structural joint is met to the concrete, fills in the hollow closed rubber stagnant water bag of the fold that has the charging connector in concrete structural joint recess, pressurizes in to rubber stagnant water bag through the charging connector, makes rubber stagnant water bag combine closely with concrete structural joint recess, seals the seam. Pre -buried in the land side structural joint below the hollow closed rubber stagnant water bag of fold have a sealant. More than the hollow closed rubber stagnant water bag of fold meet in the water side structural joint after insert the high -molecular polymer who easily clears away the change. The utility model discloses the leakiness leads to leaking, precast concrete crew cut seam prevention of seepage effect is not good and the waterstop damages the high shortcoming of change cost to have avoided near pre -buried waterstop of traditional cast in situ concrete to vibrate, and the construction is simple swift, and later maintenance is convenient, and the expense is hanged down.
Description
Technical field
This utility model relates to a kind of hydraulic structure structure, a kind of for xoncrete structure seam
Leakage preventing structure.
Background technology
The concrete of hydraulic engineering, on the premise of ensureing structural safety, most important purpose is exactly antiseepage.
Once there is seepage failure, not only supply water and can not get ensureing, the life wealth littoral to hinge downstream and circuit
Produce safety and cause great threat.
Use near embedded water stop band, waterstop the closeest owing to vibrating between the structural joint of cast-in-place concrete at present
Often become structure weakest link in fact, leak and happen occasionally, and once destroyed stop-water, waterstop is changed
During maintenance, adjacent concrete all must be removed, and involves great expense；Precast concrete is more to flush, between seam not
If sealing, only rely on and be layed in the geotextiles of bottom and carry out antiseepage, but the production technology of geotextiles and construction matter
Amount is difficult to ensure that, in Practical Project, anti-seepage effect is poor.If the waterstop antiseepage that can make cast-in-place concrete is imitated
Fruit more preferably, or is further added by one seepage control measure on the basis of precast concrete geotextiles antiseepage, then
Xoncrete structure will be more safe and reliable.
Utility model content
It is obvious that technical problem to be solved in the utility model is to provide a kind of stagnant water effect, it is easy to construction,
It is easy to later maintenance, replacing, the leakage preventing structure for xoncrete structure seam that use cost is relatively low.
In order to solve the problems referred to above, what this utility model was used technical scheme is: a kind of for coagulation
Soil structure seam leakage preventing structure, concrete meet water side structure seam in prefabricated or be cast with than structural joint seam wide
Groove, in xoncrete structure seam groove, fill in the closing rubber water-proof of the fold hollow with charging connector
Bag, is pressurizeed in rubber water-proof bag by charging connector, makes rubber water-proof bag tight with xoncrete structure seam groove
Close combination, closure seam.
It is embedded with pointing in the land side structural joint closing below rubber water-proof bag of fold hollow.
Described pointing is closed-cell foam plate or Colophonium plank.
Insert easy-clear after in the side structure seam that meets water closing more than rubber water-proof bag of fold hollow to change
High molecular polymer.
Described high molecular polymer is polysulfide sealing compound.
Described xoncrete structure seam groove is rhombus, circular or square.
The beneficial effects of the utility model: avoid around current cast-in-place concrete pre-burried rubber fastening band
Structural weak, after antiseepage is the best and waterstop lost efficacy, it is necessary to dismantling concrete reinstalls waterstop
Drawback, and the another road seepage control measure in addition to geotextiles can be provided for precast concrete.It installs simple,
Convenient maintenance and replacement, it is not necessary to destroying former xoncrete structure, later stage operational and administrative expenses is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the leakage preventing structure that this utility model stitches for xoncrete structure.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, the leakage preventing structure for xoncrete structure seam of the present utility model meets water at concrete
Side structure stitches prefabricated in 5 or is cast with the groove 6 wider than structural joint seam, stitches groove 6 at xoncrete structure
Inside fill in the closing rubber water-proof bag 1 of the fold hollow with charging connector 2, by charging connector 2 to rubber
Pressurization in sealing bag 1, makes rubber water-proof bag 1 combine closely with xoncrete structure seam groove 6, and closing connects
Seam, reaches antiseepage purpose.
It is embedded with pointing in the land side structural joint closing rubber water-proof bag less than 1 of fold hollow
3.Described pointing 3 is closed-cell foam plate or Colophonium plank.
Easy-clear is inserted more after in the side structure seam that meets water closing rubber water-proof bag more than 1 of fold hollow
The high molecular polymer 4 changed.High molecular polymer 4 is polysulfide sealing compound.
Described xoncrete structure seam groove 6 is rhombus, circular or square.
Specifically, stitch the 5 prefabricated or grooves 6 of cast-in-place one-tenth definite shape at the concrete side structure that meets water,
Until seam face dock after, fill in the closing rubber water-proof bag 1 of fold hollow from upstream face structural joint, by
Every the inside inflating pressure of charging connector 2, make closing rubber water-proof bag 1 expand, compressing structure seam groove 6
Concrete wall, reach the purpose of water seepage prevention.
Embodiment described above is merely to illustrate technological thought of the present utility model and feature, and its purpose exists
In making those skilled in the art it will be appreciated that content of the present utility model implementing according to this, it is impossible to only with
The present embodiment limits the scope of the claims of the present utility model, and the spirit disclosed in the most all this utility model is made
Equal change or modify, still fall in the scope of the claims of the present utility model.
