Fasteners 3 are assembled inside a8 and mounting hole b; fasteners 3 include fastening screws 20 and anti-loosening screws 19, fastening screws 20 are screwed with fastening nuts 21; the bottom end of fastening screws 20 is provided with anti-loosening grooves 22, and anti-loosening screws 19 are screwed into anti-loosening grooves 22; anti-loosening sleeves 9 are sleeved on the outside of anti-loosening screws 19, and three limiting posts 17 are installed on the outer wall of anti-loosening sleeves 9, the three limiting posts 17 are distributed in a triangle; the inner wall of each limiting post 17 is provided with a spiral groove 18 that cooperates with fastening screws 20;

[0029] In this technical solution, the H-shaped steel pile body 1 is an ordinary H-shaped steel pile, and an H-shaped steel pile head 2 is installed at its bottom end. A pile head cone plate 5 is set on the pile head cone plate 5, and a wedge surface is set on the pile head cone plate 5 to facilitate the pile head to penetrate into the gravel. The H-shaped steel pile head 2 is installed to the bottom end of the H-shaped steel pile body 1 by fasteners 3. The setting of fasteners 3 can improve the connection strength between the two and prevent the connection from loosening. An anti-loosening groove 22 is set at the bottom end of the fastening screw 20. The anti-loosening screw 19 is screwed in. Three limiting posts 17 installed on the anti-loosening cylinder 9 outside the anti-loosening screw 19 hold the fastening nut 7, thereby limiting the fastening nut 7 in a circumferential manner. The spiral groove 18 on the limiting post 17 engages with the fastening screw 20, thereby limiting the anti-loosening cylinder 9 and the anti-loosening screw 19.

[0030] In some technical solutions, the inner wall of the anti-detachment cylinder 9 is provided with a reverse internal thread, and the outer part of the anti-detachment screw 19 that fits with the anti-detachment cylinder 9 is provided with a reverse external thread, and the reverse internal thread and the reverse external thread are matched.

[0032] In some technical solutions, a turntable 10 is installed at the end of the anti-detachment screw 19, and a cross groove is opened on the outer wall of the turntable 10.

[0033] In this technical solution, the turntable 10 facilitates the rotation of the anti-loosening screw 19, and the cross groove facilitates operation with a screwdriver.

[0034] In some technical solutions, the outer wall of the fastening nut 21 is provided with an annular groove 11, and the end of the limiting post 17 is set in the annular groove 11.

[0035] In this technical solution, when the anti-loosening screw 19 is screwed into the anti-loosening screw groove 22, the anti-loosening cylinder 9 will rotate accordingly.

With further tightening, the annular rubber sheet 15 contacts the fixing ring 12. The annular rubber sheet 15 deforms due to the action of the fixing ring 12, sealing the screw hole. The spring 16 is located on the upper side of the annular pressure plate 14, causing the annular pressure plate 14 to be pressed downward due to the action of the spring 16. The compression block 13 is pressed downward due to the action of the annular pressure plate 14, causing the compression block 13 to further compress the edge of the annular rubber sheet 15, thereby improving the sealing effect. The annular pressure plate 14 is located on the upper side of the fixing ring 12, the spring 16 is located on the upper side of the annular pressure plate 14, and the annular rubber sheet 15 is located on the lower side of the fixing ring 12. The compression block 13 is fixedly installed at the lower edge of the annular pressure plate 14.

[0038] In some technical solutions, both ends of the pile head plate 201 are equipped with snap-fit ​​plates 4, and the top of the snap-fit ​​plate 4 is provided with a snap-fit ​​groove 7, and the wing plate of the H-shaped steel pile body 1 is inserted into the snap-fit ​​groove 7.

[0039] In this technical solution, when installing the H-shaped steel pile head 2, the wing plate of the H-shaped steel pile body 1 can be installed into the snap-fit ​​groove 7 for matching installation.

[0040] Working principle: When using, align the mounting hole a8 on the H-beam steel pile head 2 with the mounting hole b on the H-beam steel pile body 1, insert the fastening screw 20 on the fastener 20, screw the fastening nut 21 onto the fastening screw 20, and then install the anti-detachment sleeve 9 and the anti-detachment screw 19.
