[0002] Concrete drainage pipes are drainage pipes made of concrete and steel reinforcement. They are widely used in urban and rural drainage systems as well as industrial and agricultural drainage facilities. These pipes have good durability and strength characteristics, can withstand large pressure and gravity loads, and are corrosion-resistant and high-temperature resistant. Their smooth inner walls can effectively reduce water flow resistance and improve discharge efficiency, preventing blockages.

[0003] In existing drainage pipe technology, pipe clamps are usually used to connect two pipes during installation. While this makes it easier for workers to connect the two pipes, the connection point is prone to leakage after long-term use, which reduces the service life of the reinforced concrete drainage pipe.

[0027] Reference Figure 1-6This utility model provides an easy-to-install reinforced concrete drainage pipe, including a first pipe 1, a second pipe 2 arranged on the side of the first pipe 1, a sealing snap-fit ​​3 fixedly connected to the outer contour of the first pipe 1 near the second pipe 2, a sealing snap-fit ​​4 detachably connected to the sealing snap-fit ​​3 fixedly connected to the outer contour of the second pipe 2 near the first pipe 1, a connecting pipe 5 snapped onto the opposite side of the first pipe 1 and the second pipe 2, and fixing bolts 6 are provided at the four corners of the sealing snap-fit ​​4 and bolted to the sealing snap-fit ​​3.

[0028] First, place the connecting pipe 5 inside the sealing clamp 3. Then, use the sealing clamp 3 and the sealing clamp 4 to clamp and seal the first pipe 1 and the second pipe 2. Next, connect the first pipe 1 and the second pipe 2 to the connecting pipe 5 respectively. This further enhances the sealing effect at the connection point during pipe use, completing the seal and preventing leaks at the connection point that could easily occur over time, thus reducing the pipe's lifespan.

[0029] The sealing snap-fit ​​component 3 includes a sealing snap-fit ​​component 3 fixedly connected to the outer contour of the first pipe 1 near the second pipe 2. A fixing ring 32, which is fixedly connected to the outer contour of the second pipe 2, is fixedly connected to the end of the sealing snap-fit ​​component 3 near the second pipe 2. Fixing plates 33 are fixedly connected to both sides of a fixing plate 33. A limiting groove 34 is provided on the fixing plate 33, and a rectangular sealing groove 35 is provided at the bottom of the limiting groove 34. A lower arc-shaped sealing groove 36 is provided at the end of the lower arc-shaped plate 31 away from the fixing ring 32. An upper arc-shaped sealing groove 37 is provided on one side of the fixing ring 32. A connecting groove 38 is provided at the end of the lower arc-shaped sealing groove 36 and the upper arc-shaped sealing groove 37 near the rectangular sealing groove 35. The sealing snap-fit ​​component 4 includes an upper arc-shaped plate 41 fixedly connected to the outer contour of the second pipe 2 near the first pipe 1. The upper arc-shaped plate 41 is fixedly connected to the end of the upper arc-shaped plate 41 near the first pipe 1. A fixing ring 42 is fixedly connected to the sealing snap-fit ​​part 4. Fixing plates 43 are fixedly connected to both sides of the sealing snap-fit ​​part 4. A limiting slide rod 44 is fixedly connected to the bottom of the fixing plate 43. A limiting slide rod 44 is fixedly connected to the bottom of the limiting slide rod 44. An upper arc-shaped sealing strip 46 is fixedly connected to the end of the sealing snap-fit ​​part 4 away from the fixing ring 42. A lower arc-shaped sealing strip 47 is fixedly connected to one side of the fixing ring 42. A rectangular sealing strip 45 is snapped into the rectangular sealing groove 35. The inner wall of the upper arc-shaped sealing strip 46 is engaged with the inner wall of the lower arc-shaped sealing groove 36, and the lower arc-shaped sealing strip 47 is engaged with the inner wall of the upper arc-shaped sealing groove 37. Both ends of the upper arc-shaped sealing strip 46 and the lower arc-shaped sealing strip 47 are provided with connecting strips that connect to the rectangular sealing strip 45. The connecting strips are engaged in the connecting groove 38. The main view shape of the limiting slide groove 34 is trapezoidal, and the main view shape of the limiting slide rod 44 is the same as that of the limiting slide groove 34.

[0030] First, place the connecting pipe 5 inside the lower arc-shaped plate 31. Then, move the second pipe 2 towards the first pipe 1 to align and engage the first pipe 1 and the second pipe 2. As the second pipe 2 moves, it drives the limiting slide rod 44 to move into the limiting slide groove 34, which also causes the rectangular sealing strip 45 to move into the rectangular sealing groove 35. When the second fixing ring 42 moves to the second fixing ring 42, the lower arc-shaped sealing strip 47 is engaged with the inner wall of the upper arc-shaped sealing groove 37, and the upper arc-shaped sealing strip 46 is engaged with the inner wall of the lower arc-shaped sealing groove 36. At the same time, the connecting strip is engaged in the connecting groove 38. Simultaneously, the trapezoidal limiting slide rod 44 and the limiting... The positioning groove 34 improves the limiting effect after the sealing snap-fit ​​parts 3 and 4 are engaged. The limiting rod 44, rectangular sealing strip 45, upper arc sealing strip 46, lower arc sealing strip 47 and connecting strip, which are respectively engaged in the inner walls of the limiting groove 34, rectangular sealing groove 35, lower arc sealing groove 36, upper arc sealing groove 37 and connecting groove 38, effectively seal the sealing snap-fit ​​parts 3 and 4 installed together, and increase the sealing effect when the two pipes are connected. Then, the sealing snap-fit ​​parts 3 and 4 are fixed with the fixing bolts 6 to increase their fixing effect.

[0031] The two ends of the connecting pipe 5 are fixedly connected with plug rings 51. The first pipe 1 and the second pipe 2 are provided with plug grooves 52 that are adapted to the plug rings 51 on the side near the plug rings 51. The outer contour of the plug rings 51 is provided with sealing rubber rings 53 in an array. The inner wall of the plug grooves 52 is provided with an annular sealing groove 54 that is adapted to the sealing rubber rings 53.

[0032] During the installation of sealing snap-fit ​​part 3 and sealing snap-fit ​​part 4, the first pipe 1 and the second pipe 2 are also snapped together, and the insertion rings 51 at both ends of the connecting pipe 5 are respectively snapped into the insertion grooves 52 opened on the first pipe 1 and the second pipe 2. The sealing rubber rings 53 on the outer contour of the insertion rings 51 are snapped into the annular sealing grooves 54 opened on the inner wall of the insertion grooves 52. Thus, a labyrinth seal is formed by the array of sealing rubber rings 53 and annular sealing grooves 54, which increases the sealing effect at the connection after the first pipe 1 and the second pipe 2 are assembled and spliced.

[0033] Working principle: First, the connecting pipe 5 is placed inside the lower arc plate 31. Then, the second pipe 2 is moved towards the first pipe 1 to align and engage the first pipe 1 and the second pipe 2. As the second pipe 2 moves, it drives the limiting slide rod 44 to move into the limiting slide groove 34, which also causes the rectangular sealing strip 45 to move into the rectangular sealing groove 35. When the second fixing ring 42 moves to the second fixing ring 42, the lower arc sealing strip 47 is engaged with the inner wall of the upper arc sealing groove 37, and the upper arc sealing strip 46 is engaged with the inner wall of the lower arc sealing groove 36. At the same time, the connecting strip is engaged in the connecting groove 38. The trapezoidal limiting slide rod 44 and the limiting slide groove 34 make the limiting effect of the sealing engagement part 1 3 and the sealing engagement part 2 4 better after being engaged. The engagement of the two parts is achieved by engaging the limiting slide groove 34, the rectangular sealing groove 35, the lower arc sealing groove 36, the upper arc sealing groove 37 and the connecting groove respectively. The limiting slide bar 44, rectangular sealing strip 45, upper arc-shaped sealing strip 46, lower arc-shaped sealing strip 47, and connecting strip on the inner wall of 38 effectively seal the sealing snap-fit ​​part 1 3 and sealing snap-fit ​​part 2 4 installed together. Then, the sealing snap-fit ​​part 1 3 and sealing snap-fit ​​part 2 4 are bolted together with the fixing bolt 6. When installing the sealing snap-fit ​​part 1 3 and sealing snap-fit ​​part 2 4, the first pipe 1 and the second pipe 2 are also snapped together. Then, the insertion rings 51 at both ends of the connecting pipe 5 are respectively snapped into the insertion grooves 52 opened on the first pipe 1 and the second pipe 2. The sealing rings 53 on the outer contour of the insertion rings 51 are snapped into the annular sealing grooves 54 opened on the inner wall of the insertion grooves 52. Thus, the array of sealing rings 53 and annular sealing grooves 54 form a labyrinth seal. After the first pipe 1 and the second pipe 2 are assembled and spliced, the sealing effect at their connection is increased.
