[0002] Before excavation, a support structure is usually set up around the foundation pit to prevent landslides during the subsequent excavation of the foundation pit. For ordinary soil or hard soil, the current support structure mostly uses reinforced concrete support piles or steel sheet piles. During the construction of reinforced concrete support piles, a pile hole is first drilled, and then a steel cage is placed in the pile hole. Then concrete is poured into the pile hole. After the concrete is formed, a reinforced concrete support pile is formed.

[0003] However, in the process of pouring concrete into the pile hole, the steel cage tends to float up, resulting in weak force on the bottom of the formed reinforced concrete support pile. Therefore, this needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0022] See also Figure 1-4 , this patent provides a technical solution: a supporting pile with an anti-floating structure, comprising a steel bar pile rod 1, a positioning rib 2 and a fixing hoop 3, the fixing hoop 3 is welded on the outside of the steel bar pile rod 1, the positioning rib 2 is welded on the outside of the steel bar pile rod 1, and the steel bar pile rod 1 is inserted into an external pile hole;

[0023] The steel bar pile rod 1 is inserted into the external pile hole by an external crane. At this time, the positioning bar 2 will fit with the inner wall of the pile hole to improve the strength of the device. After the device is sunk into the pile hole, grouting can be injected into the pile hole through the primary grouting pipe 12. During the grouting process, the primary grouting pipe 12 needs to be pulled out at a uniform speed, and it is necessary to ensure that the primary grouting pipe 12 is always located below the slurry surface;

[0024] After the first grouting is completed, after waiting for a period of time, the second high-pressure grouting is performed through the second grouting pipe 13;

[0025] A fixing tube 4 is inserted and installed on both the left and right sides of the outer side of the fixing hoop 3, a connecting tube 5 is installed inside the fixing hoop 3, and the two ends of the connecting tube 5 are respectively connected with the two fixing tubes 4, a screw 6 is rotatably installed in the two fixing tubes 4, and a connecting rod 7 is rotatably installed in the connecting tube 5, and the two ends of the connecting rod 7 are respectively connected to the side walls of the two screws 6;

[0026] The anti-floating structure of the device is formed by the screw 6, the threaded tube 8, the top rod 9 and the top plate 10;

[0027] After the device is sunk into the pile hole and before grouting, the screw 6 needs to be rotated to move the threaded tube 8 outside the screw 6 outward so that the top plate 10 is pushed into the side wall of the pile hole to fix the device and prevent the device from floating up during grouting.

[0028] Because the device connects two screw rods 6 together through a connecting rod 7, when one screw rod 6 is rotated, the other screw rod 6 will also rotate accordingly, so that the fixing hoop 3 is always in the middle of the pile hole, avoiding the deflection of the steel pile rod 1;

[0029] The ends of the two screw rods 6 outside the fixed tube 4 are sleeved with a threaded tube 8, the side wall of the threaded tube 8 is installed with a push rod 9, and the side wall of the push rod 9 is installed with a top plate 10, which can be inserted into the inner wall of the external pile hole.

[0030] Specifically, the side wall of the fixing hoop 3 is installed with a rotation-stopping mechanism 11, which includes a square rod 111, a square hole 112 and a limit block 113. The inner wall of the threaded tube 8 is installed with a square rod 111, and the side wall of the screw rod 6 is provided with a square hole 112. The square rod 111 is inserted and installed in the square hole 112. The limit block 113 is installed at one end of the square rod 111 located in the square hole 112, and the limit block 113 can slide in the square hole 112.

[0031] The cooperation between the square rod 111 and the square hole 112 can prevent the threaded barrel 8 from rotating together with the screw rod 6 when the screw rod 6 is rotated.

[0032] Specifically, it also includes a primary grouting pipe 12 and a secondary grouting pipe 13. The upper wall of the fixing hoop 3 is provided with a main hole 14 and a secondary hole 15. The steel pile rod 1 is inserted and installed in the main hole 14. There are two secondary holes 15. The primary grouting pipe 12 and the secondary grouting pipe 13 are respectively inserted into the two secondary holes 15.

[0033] Specifically, a spherical groove 16 is formed on the side wall of the limit block 113, and a ball 17 is installed in the spherical groove 16, and the ball 17 fits with the inner wall of the square hole 112;

[0034] By providing the ball 17 , the limit block 113 can slide more smoothly in the square hole 112 , thus avoiding the jamming phenomenon.

[0035] Specifically, a threaded hole 18 is provided on the side wall of the threaded barrel 8, and a bolt 19 is rotatably installed in the threaded hole 18, and the bolt 19 can fit with the side wall of the screw rod 6;

[0036] After the top plate 10 is inserted into the side wall of the pile hole, the bolt 19 can be screwed to fix the position of the threaded barrel 8 to prevent the threaded barrel 8 from moving.

[0037] Specifically, the top plate 10 is arc-shaped, and the side wall of the top plate 10 is welded with a pin 20;

[0038] The nails 20 can further increase the friction between the top plate 10 and the inner wall of the pile hole, and further improve the anti-floating ability of the device.

[0039] Working principle: insert the steel bar pile rod 1 into the external pile hole through an external crane, at which time the positioning rib 2 will fit with the inner wall of the pile hole to improve the strength of the device. After sinking the device into the pile hole, rotate the screw 6 to move the threaded tube 8 outside the screw 6 outward so that the top plate 10 is pushed into the side wall of the pile hole to fix the device, and fix the position of the threaded tube 8 through the bolt 19. Then, grouting is performed into the pile hole through the primary grouting pipe 12. During the grouting process, the primary grouting pipe 12 needs to be pulled out at a uniform speed, and it is necessary to ensure that the primary grouting pipe 12 is always below the slurry surface. After the primary grouting is completed, wait for a period of time, and then perform secondary high-pressure grouting through the secondary grouting pipe 13, and then maintain the concrete support piles. After the maintenance is completed, the support piles are completed.
