Accompanying drawing explanation
The above and other feature of the present utility model, character and advantage become more obvious by the description by below in conjunction with drawings and Examples, wherein:
Fig. 1 is the schematic diagram of waterproof sealing system of joints of segment of the integrated pipe canal of an embodiment of the utility model.
Fig. 2 is the viewgraph of cross-section of hydro-expansive rubber bar in Fig. 1.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
It should be noted that Fig. 1 and Fig. 2 are all only as example, it is not to draw according to the condition of equal proportion, and should not using this as the protection domain of the utility model actual requirement is construed as limiting.
As shown in Figure 1, the waterproof sealing system of the joints of segment of integrated pipe canal is that the docking of two precast assembly tube couplings 1,2 is sealed.The end construction of tube coupling 1,2 is roughly the same, therefore in case of no particular description, the explanation of tube coupling 1 is also applicable to the structure of tube coupling 2.Tube coupling 1 is from cross section, and it is into the annular shape of profiling, and the municipal public use pipelines such as electric power, communication, water supply can be arranged in its inside.The docking end face 10 of tube coupling 1 has annular groove 15, and annular groove 15 is roughly positioned at the radially middle part of docking end face 10, is installed with hydro-expansive rubber bar 11 (abbreviation rubber strip) in annular groove 15.
Rubber strip 11 is also to arrange ringwise along annular groove 15, its shape of cross section as shown in Figure 2, in namely the fit surperficial side 110 of groove 15 of dorsal part, there are a plurality of arch openings 111,112, in a side 120 that forms water blocking tape interface, protrude and be provided with sealing surface 121.
After two tube coupling 1,2 docking, rubber strip 11 in groove 15, the sealing surface 121 of the rubber strip 21 in groove 25 also dock, thereby form water blocking tape interface, if the precompression applying on two rubber strips 11,21 in a suitable scope, its sealing performance just can be guaranteed.
Tube coupling 1 also has a plurality of bolts hole 12 that are uniformly distributed circumferentially, the end of tube coupling 1 is provided with counterbore 13, arch screw bolt (not shown) is passed the bolt hole 12 of tube coupling 1, the bolt hole 22 of tube coupling 2, two ends by fastening nuts in counterbore 13,23, on nut, apply after enough pretightning forces, can fill counterbore 13,23 with cement.Arch screw bolt links together tube coupling 1,2, and the power of its connection is delivered on two rubber strips 11,21, makes the docking of two rubber strips 11,21 be applied with precompression.In an embodiment of the present utility model, the construction moment of torsion of each arch screw bolt is 0.9KNm, correspondingly executes water blocking tape interfacial stress and is not less than 1.5MPa.
After two tube coupling 1,2 docking, its interface 10,20 is laminating in fact also.In addition, rubber strip 11,21 fixing in groove 15,25 can be glue coated in groove 15,25, then rubber strip 11,21 is placed in groove 15,25, and strikes tightly with rubber hammer, so that the concrete surface of the surface of rubber strip 11,21 and groove 15,25 is closely connected.
Continuation, with reference to Fig. 1, inwardly encircles limit in the footpath of tube coupling 1,2 and also provides filleting groove 14,24, after docking, can carry out filleting with cement.
Hydro-expansive rubber bar 11,21 can expand when meeting water, and rubber strip 11,21 itself possesses compressibilty, therefore, when applying enough prestressing force, the two just can reach good sealing, even if anti-water termination together is only set, also can reaches good sealing effectiveness.
Although previous embodiment is to take the tube coupling docking of integrated pipe canal to describe as example, the utility model is also suitable for the seam waterproof of assembled steel reinforced concrete pipe canal.
Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, within not departing from spirit and scope of the present utility model, can make possible change and modification.Therefore, every content that does not depart from technical solutions of the utility model, any modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection domain that the utility model claim defines.
