Detailed description of the invention
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more; Term " on ", D score, "left", "right", " interior ", " outward ", " front end ", " rear end ", " head ", the orientation of the instruction such as " afterbody " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second ", " the 3rd " etc. only for describing object, and can not be interpreted as instruction or hint relative importance.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " is connected ", " connection " should be interpreted broadly, such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
Embodiment one
As shown in Fig. 1, Fig. 6, the curved section tube coupling joint described in the present embodiment, it comprises the first waterstop 1 and the second waterstop 2; First waterstop 1 and the second waterstop 2 are connected to form joint ring, and joint ring is arranged at the end of curve immersed tube tube coupling 8, and the first waterstop 1 is different from the hardness of the second waterstop 2, thus form hardness difference in both sides.And the joint ring overall dimensions that waterstop is formed is slightly less than tunnel outline 7.
Further, the hardness of the first waterstop 1 and the hardness range of the second waterstop 2 are 25-80 Shao Er, but need ensure that the hardness of the first waterstop 1 is different from the hardness of the second waterstop 2.Offset the impact of water pressure moment generation by the hardness difference of both sides, thus realize solving curve tube coupling produces off normal problem owing to cannot evenly crimp.
