[0020] Please refer to Figures 1-7 A multifunctional lightweight prefabricated drainage well connecting structure, comprising a bottom section 1, a middle section 2 and a top section 3, the bottom section 1 is arranged at the bottom of the drainage well, the middle section 2 is arranged between the bottom section 1 and the top section 3, the top section 3 is provided with a well lid 11 at the port, and the bottom section 1, the middle section 2 and the middle section 2 and the top section 3 are spliced through the connecting structure; wherein the inner and outer diameters of the bottom section 1, the middle section 2 and the top section 3 are consistent, and the three are vertically spliced.

[0021] In actual use, the length of the middle section 2 is prefabricated according to the demand, and the top end and the bottom end of the middle section 2 are also convenient for splicing. The spliced drainage well structure is stable and has good waterproof effect.

[0022] In this embodiment, the connecting structure comprises an annular I-steel joint 4, the I-steel joint 4 is embedded in the end face (the surface of the bottom section, the bottom surface and the top surface of the middle section, and the bottom surface of the top section) of each pipe section, and the two I-steel joints 4 are fixedly connected through connecting bolts 6.

[0023] The I-steel joint 4 is provided with a plurality of mounting holes 12 in the circumferential array, the connecting bolts 6 pass through the mounting holes 12, and in use, the mounting holes 12 on the upper and lower I-steel joints 4 correspond to each other, and after the corresponding connecting bolts 6 are replaced, the two are fixedly connected, realizing the splicing of each pipe section, which can greatly improve the strength of the drainage well.

[0024] In order to further improve the strength and waterproofness of the pipe joint position, the I-shaped steel joint 4 is provided with an annular grouting guide pipe 5 on the inner and outer sides, a plurality of steel pipes 41 are arranged on the vertical steel plate of the I-shaped steel joint 4, the two ends of the steel pipe 41 are communicated with the inner and outer grouting guide pipes 5, the circumference of the grouting guide pipe 5 is provided with a grout overflow hole, the pipe joint is provided with a grouting formwork at the joint position, the grouting formwork comprises an annular inner steel formwork 8 and an outer steel formwork 9, the inner steel formwork 8 is fixed by inner embedded bolts 7, the outer steel formwork 9 is fixed by outer embedded bolts 10, the surface of the outer steel formwork 9 is provided with a grouting hole 13, a grout outlet hole 14 and an air outlet hole 15, and the outer grouting guide pipe 5 is communicated with the grouting hole 13.

[0025] When each pipe joint is fixed by the connecting bolt 6, the inner and outer steel formworks are arranged at the joint position, and then the pressurized concrete grout is injected into the outer grouting guide pipe 5 at the grouting hole 13; at this time, the grout first enters the outer grouting guide pipe 5 at the grouting hole 13, and then the grout in the grouting guide pipe 5 enters the inner grouting guide pipe 5 through the steel pipe 41; and the grout in the two grouting guide pipes 5 flows out at the grout overflow hole, so that the grout fills the I-shaped steel joint 4 between the inner steel formwork 8 and the outer steel formwork 9, further improves the connection stability, makes the service life longer, and improves the waterproof performance of the joint position by the pouring of the concrete, and has high practicability.

[0026] During the grouting process, the internal air is discharged at the air outlet hole 15, and when the grout flows out of the grout outlet hole 14, it indicates that the inside is filled, and then the formwork can be removed after solidification.

[0027] Based on the above embodiment, waterproof paint can also be brushed on the joint of the pipe joint position for waterproof secondary strengthening.
