As an embodiment of the present invention, as shown in fig. 1, 2 and 7, the sealing mechanism 4 includes an annular tooth block 41, an annular tooth space 42, a glue outlet hole 43, a sealing film 44 and a sharp rod 45, the annular tooth block 41 is fixedly connected to an outer side position of an upper end outer surface of the bottom pile 1 close to the blind hole 31, an annular tooth space 42 is opened on a lower end outer surface of the connecting pile 11 close to the annular tooth block 41, the annular tooth block 41 and the annular tooth space 42 are attached to each other, the glue outlet hole 43 is opened on a top end concave portion of an inner surface of the annular tooth space 42, the sealing film 44 is fixedly connected to an opening of the glue outlet hole 43, the sealing glue is filled in a position of an inner portion of the connecting pile 11 close to an upper end of the annular tooth space 42, and the sharp rod 45 is fixedly connected to a position of an upper end of the annular tooth block 41 close to the glue outlet hole 43.
When the pipe pile is in work, because the underground soil layer environment is complex, the traditional pipe pile connection mode has poor sealing performance and corrosion resistance, and the pipe pile is buried underground for a long time, so that the welded part is easily corroded to generate cracks, underground water permeates into the inside of a welded part, and the stability of the pipe pile is influenced.
As an embodiment of the present invention, as shown in fig. 2 and 3, a protrusion 20 is fixedly connected to a central position of an upper outer surface of the connecting rod 21, and a plurality of through holes 211 are formed in an upper outer surface of the protrusion 20.
In operation, because the upper end of the connecting rod 21 is flush with the upper end of the clamping rod 26, when the connecting block 14 enters the connecting groove 12 and the connecting block 14 contacts with the top end of the inner surface of the circular groove 29, the clamping rod 26 also contacts with the top end of the inner surface of the through groove 27, so that when the clamping rod 26 rotates along with the connecting rod 21, the clamping rod 26 can rub against the through groove 27, which is not favorable for the clamping rod 26 to enter the first clamping groove 28 smoothly, thereby affecting the normal operation of the connecting mechanism 2.
As an embodiment of the present invention, as shown in fig. 2 and 3, a movable block 212 is movably connected to a center position of a top end of an inner surface of the circular groove 29, an annular outer surface of the movable block 212 is movably connected to the circular groove 29 through a bearing 213, a plurality of second limit rods 214 are fixedly connected to an outer surface of a lower end of the movable block 212, and the second limit rods 214 are engaged with the through holes 211.
In operation, when the connecting block 14 enters the connecting groove 12, the protrusion 20 contacts with the top end of the inner surface of the circular groove 29, so that when the protrusion 20 rotates along with the connecting rod 21, the protrusion 20 rubs against the circular groove 29, which is not beneficial to the clamping rod 26 to smoothly enter the first clamping groove 28, thereby affecting the normal operation of the connecting mechanism 2.
The working principle is as follows: when the connecting mechanism 2 is arranged, the connecting pile 11 is hoisted by a crane, the connecting pile 11 is controlled to move to enable the connecting block 14 to enter the connecting groove 12, the clamping rod 26 enters the through groove 27, the connecting pile 11 continues to move downwards to enable the connecting rod 21 to be contacted with the top end of the inner surface of the circular groove 29, the connecting rod 21 moves downwards under the action of gravity of the connecting pile 11 to enable the torsion spring 25 to be compressed, the inverted L-shaped groove 22 moves downwards along with the connecting rod 21 to enable the lower end part of the first limiting rod 23 and the inverted L-shaped groove 22 to be separated from each other, the limiting effect of the first limiting rod 23 on the connecting rod 21 disappears, the connecting rod 21 and the vertical rod 24 rotate under the torsion action of the torsion spring 25 to drive the clamping rod 26 to rotate to enter the first clamping groove 28, when the connecting pile 11 moves downwards to enable the connecting block 14 to be attached to the connecting groove 12, the fixing rod 32 enters the blind hole 31, through setting up sealing mechanism 4, will connect stake 11 to remove downwards through the loop wheel machine, make cyclic annular tooth piece 41 and cyclic annular tooth's socket 42 laminate each other, the seal membrane 44 is punctured to sharp pole 45, makes sealed glue overflow, because go out gluey hole 43 and correspond cyclic annular tooth piece 41 top for sealed glue spreads along cyclic annular tooth piece 41 both ends, will seal glue evenly to coat between cyclic annular tooth piece 41 and cyclic annular tooth's socket 42.
