[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0030] An easy-to-install reinforced concrete drainage pipe, such as Figure 1As shown, the device includes a pipe body 1, a quick-connect structure 2, and a positioning and guiding structure 3. The pipe body 1 has a socket 4 and a spigot 5 at both ends. The quick-connect structure 2 is located on the outer wall of the socket 4 and spigot 5. The positioning and guiding structure 3 is located at the socket 4 and spigot 5 of the pipe body 1. The quick-connect structure 2 includes an annular groove 201, an annular groove 202, and a clamp 203 (see reference). Figure 3 ) and fastening bolt 204 (reference) Figure 3 ), Annular groove 1 201 and Annular groove 202 are respectively provided on the outer walls of both ends of the pipe body 1, and clamp 203 is sleeved on the outside of the spigot 5 and the socket 4. The inner wall of clamp 203 is provided with a locking block 6 that is adapted to Annular groove 1 201 and Annular groove 202 (see reference). Figure 3 The fastening bolt 204 is used to fasten the clamp 203 onto the annular groove 201 and the annular groove 202. The positioning guide structure 3 includes a guide protrusion 301 and a guide groove 302. The guide protrusion 301 is set on the outer circumferential surface of the socket 5, and the guide groove 302 is set on the inner circumferential surface of the socket 4. The guide protrusion 301 and the guide groove 302 are adapted to each other. The design of the quick connection structure 2 and the positioning guide structure 3 makes the installation process of reinforced concrete drainage pipe simple and easy. It does not require complicated operations and professional technicians. The pipe connection can be completed by rotation and fastening, which greatly shortens the construction time and improves the construction efficiency, installation efficiency and accuracy. The easy-to-install reinforced concrete drainage pipe of this utility model is suitable for drainage projects with different pipe diameters and different working conditions. By adjusting the size and specifications of the quick connection structure 2 and the positioning guide structure 3, it can meet diverse engineering needs and has wide applicability.

[0031] like Figure 3 As shown, the clamp 203 consists of two semi-circular structures connected by fastening bolts 204, with locking blocks 6 distributed on the inner side of the semi-circular structures. The split design makes installation and disassembly easier, eliminating the need to put the entire clamp 203 on, saving time and labor, especially in space-constrained situations.

[0032] like Figure 3 As shown, each side of the clamp 6 that contacts the pipe body 1 is equipped with a semi-circular anti-slip rubber pad 7. By setting the anti-slip rubber pad 7, the friction can be increased to prevent the clamp 203 from sliding between the clamp and the pipe body 1. At the same time, it may reduce the wear between the metal and the concrete, and also has a certain buffering effect, thus improving the sealing performance.

[0033] like Figure 3As shown, both the guide protrusion 301 and the guide groove 302 are spiral structures with the same spiral direction. The spiral positioning and guiding structure 3 can guide the pipes to accurately connect, effectively avoiding problems such as pipe misalignment and poor joint tightness, ensuring the installation quality and sealing of the drainage pipe system. The spiral structure may also disperse stress, enhance structural stability, and improve the overall performance of the drainage system.

[0034] like Figure 3 As shown, the end faces of the spigot 5 and the socket 4, which are close to each other, are respectively provided with annular mounting groove 8 and annular mounting groove 9. Both annular mounting groove 8 and annular mounting groove 9 are provided with annular elastic sealing strip 10. By setting annular mounting groove 8, annular mounting groove 9, and elastic sealing strip, the elastic sealing strip can form a reliable sealing barrier when the pipe is connected, effectively preventing water leakage, meeting the sealing requirements of drainage projects, and reducing water waste and environmental pollution risks.

[0035] like Figure 5 As shown, the annular mounting groove 29 is designed in an inverted trapezoidal shape. By designing the annular mounting groove 29 as an inverted trapezoidal shape, the other half of the elastic sealing strip can be easily and without resistance inserted into the annular mounting groove 29 during the butt joint installation process between the pipe bodies 1.

[0036] The working process and beneficial effects of this utility model are as follows: The pipe body 1 with the socket 4 is placed in the designed position. Then, the pipe body 1 with the spigot 5 is lifted, aligning the guide protrusion 301 of the spigot 5 with the guide groove 302 of the socket 4. The pipe body 1 is slowly lowered while the spigot 5 is rotated. Under the spiral guidance of the guide protrusion 301 and the guide groove 302, the spigot 5 is gradually inserted into the socket 4. When the spigot 5 is inserted to a certain depth, the two semi-annular structures of the clamp 203 are respectively fitted onto the outside of the pipe body 1, aligning the clamping block 6 with the annular groove. Then, the two semi-annular structures are connected together using the fastening bolt 204, and the fastening bolt 204 is tightened with a wrench, causing the clamp 203 to tighten and the clamping block 6 to embed into the annular groove, completing the rapid connection of adjacent pipe bodies 1.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
