Description
Technical field
The utility model relates to a kind of tubulose hydraulic structure shrinkage joint anti-leakage structure, belongs to technical field of building construction.
Background technology
In prior art, the hydraulic structure such as most of concrete duct, culvert, inverted-siphon shrinkage joint all adopts the waterproofing materialss such as embedded rubber fastening band or matizhi, to tackle the distortion that sedimentation, temperature etc. cause.But along with the passing of service time, waterproofing materials (i.e. rubber fastening band or matizhi etc.) in shrinkage joint can follow the string gradually, be oxidized cracking or excessively occur drawing crack etc. because being out of shape, thus cause the shrinkage joint seepage of above-mentioned hydraulic structure, so not only easily causing building to stitch both sides turns black mouldy, affect attractive in appearance and using function, and safety and the durability of building can be had a strong impact at cold district Frozen-thawed cycled.
Summary of the invention
The purpose of this utility model is: the defect overcoming above-mentioned prior art, proposes the tubulose hydraulic structure shrinkage joint anti-leakage structure that a kind of structure is simple, reliability is high.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of tubulose hydraulic structure shrinkage joint anti-leakage structure, described tubulose hydraulic structure is formed by connecting by more piece pipeline, and described shrinkage joint, between adjacent channel, is filled with filler in described shrinkage joint; Described filler comprises the sealant layer that is positioned at internal layer and is positioned at skin and for preventing the bed course of sealant layer seepage; The position that described shrinkage joint is positioned at inner-walls of duct has sticked waterstop; The part that described waterstop is positioned at both sides, shrinkage joint is respectively equipped with press strip, and described press strip is fixedly connected with pipeline by crab-bolt.
The utility model in use, first retains certain thickness bed course as back lining materials outside shrinkage joint, and at inner side perfusion sealant layer, forms the first impervious body at shrinkage joint, effectively can prevent the seepage at shrinkage joint; The full compress in position that described shrinkage joint is positioned at inner-walls of duct is provided with waterstop.Like this, described shrinkage joint place inner-walls of duct pastes waterstop outward and forms second impervious body, can avoid the seepage at shrinkage joint further.
In the utility model, described bed course can select tar plastic cement mud layer or other existing material layers preventing sealant layer seepage.Described sealant layer is two component polysulfide sealing compound layer preferably, described waterstop preferred rubber waterstop; Described press strip preferable alloy press strip, particularly stainless steel press strip.
Preferably, the thickness of described bed course and the thickness ratio of sealant layer are 1:2 to 1:1.
Preferably, described crab-bolt is inserted and secured in duct wall through after press strip and waterstop.
Described in the utility model, two component polysulfide sealing compound layer is current material, have low modulus, high resiliency, freeze thawing performance good, with the feature such as Bond Performance Between Concrete is good, and adhesion strength after having good water inlet, is therefore specially adapted to the building that soaks for a long time.The position that shrinkage joint described in the utility model is positioned at inner-walls of duct has sticked waterstop, relative to the embedded rubber fastening band in shrinkage joint in prior art or matizhi, favorable elasticity, abrasion resistance, resistance to ag(e)ing and tear resistance that rubber fastening band has and the strong feature of adaptive deformation ability can be made full use of, effectively avoid the seepage at shrinkage joint.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.

Detailed description of the invention
Embodiment
As depicted in figs. 1 and 2, the tubulose hydraulic structure shrinkage joint anti-leakage structure of the present embodiment, wherein tubulose hydraulic structure to be formed by connecting (not shown) by more piece pipeline, shrinkage joint is reserved with between adjacent 2-section pipe road, as the shrinkage joint in Fig. 1 between the first pipeline 1 and second pipe 2, shrinkage joint is filled with filler along pipeline radial direction; Filler is divided into two-layer, is bed course 3-1 and sealant layer 3-2 successively outside to inside certainly; The position that shrinkage joint is positioned at inner-walls of duct has sticked waterstop 3-3; The part that waterstop 3-3 is positioned at both sides, shrinkage joint is respectively equipped with press strip 3-5, and press strip 3-5 is fixedly connected with pipeline by crab-bolt 3-4.
In the present embodiment, bed course 3-1 selects tar plastic cement mud layer, certainly, also can select any material layer preventing sealant layer seepage.
In the present embodiment, sealant layer 3-2 selects two component polysulfide sealing compound layer, and waterstop 3-3 selects rubber fastening band.Two component polysulfide sealing compound layer 3-2 is current material, have low modulus, high resiliency, freeze thawing performance good, with the feature such as Bond Performance Between Concrete is good, and adhesion strength after having good water inlet, is therefore specially adapted to the building that soaks for a long time.Certainly, sealant layer 3-2 also can adopt other sealant material.
Outside shrinkage joint, retain certain thickness bed course 3-1 like this as back lining materials, and at the two component polysulfide sealing compound layer 3-2 of inner side perfusion, form the first impervious body at shrinkage joint, just effectively can prevent the seepage at shrinkage joint.Shrinkage joint place inner-walls of duct pastes rubber fastening band 3-3 outward and just forms second impervious body, favorable elasticity, abrasion resistance, resistance to ag(e)ing and tear resistance that rubber fastening band 3-3 has and the strong feature of adaptive deformation ability can be made full use of, avoid the seepage at shrinkage joint further.
As depicted in figs. 1 and 2, in order to be fixed on adjacent inner-walls of duct securely by rubber fastening band 3-3, when metal bead 3-5 is fixedly connected with pipeline by crab-bolt 3-4, crab-bolt 3-4 inserts in duct wall through after press strip 3-5 and rubber fastening band 3-3.Press strip 3-5 preferable alloy press strip, especially stainless steel press strip.
The shrinkage joint anti-leakage structure of the present embodiment also can be used for the shrinkage joint seepage reparation (i.e. antiseep transformation) of existing tubulose hydraulic structure, first remove filler aging inside shrinkage joint during construction, and retain certain thickness filler in outside as back lining materials; Secondly remove by the greasy dirt of maxxaedium, attachment, dust and other impurities, then the two component polysulfide sealing compound of perfusion, form the first impervious body at shrinkage joint, outside last, paste rubber fastening band, and form second impervious body by crab-bolt, external pressure corrosion resistant plate by fixing for rubber fastening band.Therefore, the present embodiment also has obvious practical meaning in engineering.
The utility model is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
