Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0024] Please refer to the attached Figure 1-Figure 4 As shown, the utility model provides a technical solution: a concrete pipe culvert includes a pipe body 10, one end of the pipe body 10 is fixedly connected with a connecting pipe mouth 11, the outer surface of the connecting pipe mouth 11 is slidably sleeved with a plug-in pipe 20, the other end of the pipe body 10 is fixedly connected with an extended pipe mouth 12, the plug-in pipe 20 matches the extended pipe mouth 12, and a fixing component is provided on the extended pipe mouth 12. During assembly, the connecting pipe mouth 11 in one pipe body 10 is extended into the extended pipe mouth 12 in another pipe body 10, and the plug-in pipe 20 in one pipe body 10 is extended into the gap between the connecting pipe mouth 11 in one pipe body 10 and the extended pipe mouth 12 in the other pipe body 10.

[0025] In this embodiment, an annular clamping block 112 is fixedly connected to one end of the connecting pipe mouth 11, and an annular clamping groove 101 is opened on the side of the tube body 10 away from the connecting pipe mouth 11. The annular clamping block 112 is adapted to the annular clamping groove 101. When the connecting pipe mouth 11 in one tube body 10 extends into the extended pipe mouth 12 in the other tube body 10, the annular clamping block 112 in one tube body 10 slides and engages in the annular clamping groove 101, thereby increasing the stability of the splicing between the two tube bodies 10.

[0026] In this embodiment, the annular groove 101 is arranged on the inner side of the extended pipe mouth 12, and the inner diameter of the annular block 112 is smaller than the inner diameter of the connecting pipe mouth 11, so that the annular block 112 in one pipe body 10 can be easily engaged in the annular groove 101 in another pipe body 10.

[0027] In this embodiment, the fixing component includes four I-shaped limit blocks 13 evenly distributed on the outer surface of the extended pipe mouth 12, and the extended pipe mouth 12 is provided with an annular groove 121 on the inner side of the end away from the tube body 10, and the extended pipe mouth 12 is evenly provided with four sliding holes 122 on the outer side corresponding to the annular groove 121, and the four I-shaped limit blocks 13 are respectively slidably installed in the four sliding holes 122.

[0028] In this embodiment, the widths of both ends of the I-shaped limit block 13 are larger than the width in the middle, and the middle position of the I-shaped limit block 13 is slidably installed in the sliding hole 122 to prevent the I-shaped limit block 13 from falling off the extended pipe mouth 12.

[0029] In this embodiment, the distance between the I-shaped limit block 13 and the tube body 10 is set to be the same as the length of the plug-in tube 20, so that the I-shaped limit block 13 can slide and engage on one side of the plug-in tube 20 to fix the plug-in tube 20.

[0030] Specifically, when splicing two tube bodies 10, the connecting pipe mouth 11 of one tube body 10 is extended into the extended pipe mouth 12 of the other tube body 10, so that the annular clamping block 112 in one tube body 10 is engaged in the annular clamping groove 101 in the other tube body 10, and then the plug-in tube 20 is pushed to move on the connecting pipe mouth 11, so that the outer wall of the plug-in tube 20 on one tube body 10 is attached to the inner wall of the extended pipe mouth 12 on the other tube body 10, and the four I-shaped limit blocks 13 on the other tube body 10 are pressed respectively, so that the lower ends of the four I-shaped limit blocks 13 on the other tube body 10 are slidably engaged with the outer surface of the plug-in tube 20 on one tube body 10, so as to facilitate the fixation of the plug-in tube 20 and make the connection between the two tube bodies 10 more stable.

[0031] In this embodiment, a plurality of elongated grooves 131 are respectively formed at both ends of the I-shaped limit block 13 to increase the friction force on the surface of the I-shaped limit block 13 .

[0032] In this embodiment, four fixing blocks 111 are evenly fixedly installed on the outer surface of the connecting pipe mouth 11 , and four sliding grooves 201 are evenly opened on the inner wall surface of the plug-in pipe 20 . The four fixing blocks 111 are slidably installed in the four sliding grooves 201 respectively.

[0033] The four fixing blocks 111 cooperate with the four slide grooves 201 to enable the plug-in tube 20 to slide on the connecting tube opening 11 , thereby preventing burrs and residues on the inner wall of the extended tube opening 12 from affecting the installation of the plug-in tube 20 when the two tube bodies 10 are connected.

[0034] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
