Furthermore, when the first ring body 3231 and the second ring body 3232 are squeezed, the first ring body 3231 is pushed so that the locking ring 3235 on the first ring body 3231 slides along the annular groove 311, and then the locking ring 3235 bends and hooks the annular groove 311, thereby strengthening the connection between the first ring body 3231 and the two flanges 31.

The specific operation mode of the utility model is as follows:

When splicing the concrete piles, guide the two flanges 31 to dock so that the upper pipe pile body 10 and the lower pipe pile body 20 are aligned, and the bolt 321 is locked by the nut 324 to match the bolt 321 to connect the two flanges 31, and the first ring body 3231 and the second ring body 3232 are accommodated by the groove 322, and when the two grooves 322 are close to each other and tightened, the first ring body 3231 and the second ring body 3232 are squeezed by the groove 322. At this time, the first ring body 3231 and the second ring body 3232 are formed by the chamfers 3233 on the first ring body 3231 and the second ring body 3232. Slide along the inclined surface to fill into the groove 322, and then quickly fill the gap between the flanges 31, and the first ring body 3231 and the second ring body 3232 are squeezed and filled into the groove 322, so that the contact between the two flanges 31 is increased, thereby increasing the friction between the two flanges 31 and reducing the looseness of the connection between the flanges 31;
