[0022] Embodiment

[0023] Generally, multiple pipes are spliced in a pipeline placement ditch, and then the connection gaps of each pipe are sealed with cement. However, this sealing method results in extremely low installation and connection efficiency and cannot quickly achieve the splicing and sealing installation between pipes.

[0024] For this reason, please refer to Figures 1-4 , the present utility model provides a drainage structure for municipal engineering, including:

[0025] A drain pipe 1, with an insertion part 2 provided at the left end of the drain pipe 1 and a sleeved groove 22 provided at the other end, which is matched with the insertion part 2.

[0026] It further includes an inflatable sealing structure 3 and a clamping connection structure 4. The inflatable sealing structure 3 is installed on the outer side of the drain pipe 1, and a clamping connection structure 4 is connected between the inflatable sealing structure 3 and the drain pipe 1. The inflatable sealing structure 3 can inflate and seal the connection gap between the insertion part 2 and the sleeved groove 22, and at the same time, the setting of the clamping connection structure 4 can facilitate the splicing and fixing between two drain pipes 1.

[0027] Further, as shown in Figures 1-4As shown, it is worth specifically stating that in order to facilitate the sealing of the connection gap between the insertion part 2 and the sleeve groove 22, an inflatable sealing structure 3 is provided, which includes a rotating ring 31 rotatably connected to the periphery of the drain pipe 1 away from the insertion part 2. A plurality of connecting blocks 32 arranged in a circular array are fixedly connected to the side of the rotating ring 31 facing away from the insertion part 2. One end of each connecting block 32 is fixedly connected to an arc-shaped piston rod 33. The other end of the arc-shaped piston rod 33 extends into the inner side of the arc-shaped air cylinder 34 movably and is fixedly connected to a piston block 35. The piston blocks 35 all slide inside the arc-shaped air cylinders 34. The arc-shaped air cylinders 34 are all fixedly connected to the outer side of the drain pipe 1. An airbag ring 37 is fixedly connected to the annular groove a provided in the inner wall of the sleeve groove 22. An air inlet and outlet provided on the outer side of each arc-shaped air cylinder 34 is connected to the airbag ring 37 through an air pipe 36. The air pipes 36 are all embedded in the drain pipe 1. An annular groove b21 that cooperates with the inflated airbag ring 37 is also provided on the outer side of the insertion part 2.

[0028] Among them, after the airbag ring 37 is inflated, it can expand and fit into the annular groove b21 to seal the connection gap between the insertion part 2 and the sleeve groove 22.

[0029] Furthermore, as Figures 1-4 shown, it is worth specifically stating that in order to clamp and fix the two drain pipes 1 after docking, a clamping connection structure 4 is provided, which includes a T-shaped rotating block 45 rotatably connected to the outside of one of the connecting blocks 32 through a pin shaft 47. The end of the T-shaped rotating block 45 away from the pin shaft 47 is movably lapped in a T-shaped lapping groove 42 provided at the top of a connecting seat 41. The connecting seat 41 is fixedly connected to the outer side of the drain pipe 1 near the insertion part 2. A T-shaped column 43 is movably inserted into one side wall of the connecting seat 41. A spring 44 is movably sleeved on the outer side of the T-shaped column 43. One end of the spring 44 is connected to the outer side of the connecting seat 41, and the other end is connected to the end of the T-shaped column 43 away from the connecting seat 41. A clamping hole 46 that cooperates with the end of the T-shaped column 43 facing the T-shaped lapping groove 42 is also provided on the outer side of the T-shaped rotating block 45.

[0030] Among them, a gap is reserved between the end of the T-shaped rotating block 45 away from the pin shaft 47 and the inner wall of the T-shaped lapping groove 42. The setting of this gap can facilitate the T-shaped rotating block 45 to rotate out of the T-shaped lapping groove 42 when rotating through the pin shaft 47.

[0031] In summary, when docking between the drain pipes 1, the left end of one drain pipe 1 can be inserted into the right end sleeve groove 22 of another drain pipe 1. At the same time, by rotating the rotating ring 31, each connecting block 32 squeezes the arc-shaped piston rod 33 against the piston block 35, so that the air in the arc-shaped air cylinder 34 is squeezed and conveyed through the air pipe 36 to the airbag ring 37, thereby realizing the sealing fit of the annular groove b21 and achieving a good sealing effect. After that, the T-shaped rotating block 45 is rotationally lapped on the T-shaped lapping groove 42 provided at the top of the connecting seat 41 through the pin shaft 47. At the same time, the T-shaped column 43 is pulled, and under the reverse action of the spring 44, one end of the T-shaped column 43 can be clamped in the clamping hole 46, so as to facilitate the splicing and fixing and sealing between the two drain pipes 1, enabling the two operations to be synchronized and greatly improving the splicing and sealing efficiency.
