Technical Field

[0001] The present application relates to the technical field of precast piles, and in particular to a reinforcement structure around bored and backfilled precast piles. Background Art

[0002] Precast piles, also known as prefabricated piles, can withstand heavy loads, are strong and durable, and have a fast construction speed. They are one of the most widely used pile types. Commonly used ones are concrete solid square piles and prestressed concrete hollow pipe piles.

[0003] The stability of precast piles will be affected by the foundation itself. If the foundation soil is not good, the bearing capacity and anti-lateral displacement ability of the precast piles will be reduced, affecting the safety and stability of the project. Utility Model Content

It solves the problem that the stability of the precast piles will be affected by the foundation itself. If the foundation soil is not of good quality, the bearing capacity and lateral displacement resistance of the precast piles will be reduced, affecting the safety and stability of the project.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a bored backfill precast pile reinforcement structure, comprising a foundation, a pile body is fixedly inserted inside the foundation, four reinforcement plates are provided on the upper surface of the foundation, the outer surface of each reinforcement plate is in contact with the outer surface of the pile body, equidistantly arranged mounting rods are fixedly inserted inside the pile body, the interior of the reinforcement plates are respectively slidably connected to the outer circumferential surface of the mounting rods, and the outer circumferential surface of each mounting rod is threadedly connected with a nut.

[0006] Through the above scheme, since the stability of the precast piles will be affected by the foundation itself, if the foundation soil is not good, the bearing capacity and lateral displacement resistance of the precast piles will be reduced, affecting the safety and stability of the project. By setting a reinforcement plate on the outer surface of the pile body and using mounting rods and nuts to connect and fix the reinforcement plate to the pile body, the pile body is effectively supported and reinforced, thereby increasing the bearing capacity of the pile body, improving the lateral displacement resistance of the pile body, and thus improving the safety and stability of the project.

[0007] Furthermore, a connection groove is provided at the top of each reinforcement plate, a connection plate is provided above the foundation, and the outer surfaces of the connection plates are slidably connected to the reinforcement plates through the connection grooves.

[0008] Through the above solution, the four reinforcement plates are connected into a whole through the connection grooves and the connection plates, thereby improving the overall stability of the reinforcement structure.

[0009] Furthermore, each of the reinforcing plates is threadedly connected to two bolts, and the outer circumferential surface of the bolts is slidably plugged into the interior of the connecting plate.

[0010] Through the above solution, the reinforcement plate and the connecting plate are connected and fixed by bolts, so as to further improve the overall stability of the reinforcement structure.

[0011] Furthermore, four positioning rods are rotatably inserted inside each of the reinforcement plates, and a ground cone is threadedly connected to the outer circumferential surface of each of the positioning rods.

[0012] Through the above scheme, the positioning rod can be rotated to drive the ground cone to move downward, so that the ground cone is inserted into the foundation, the gripping ability of the reinforcement plate is increased, and the stability of the reinforcement structure is thereby improved.

[0013] Furthermore, four support plates are fixedly connected to the outer surface of each reinforcement plate, and each support plate has a triangular structure.

[0014] Through the above scheme, the reinforcement plate is supported and reinforced, the overall bearing capacity of the reinforcement plate is increased, and the stability of the precast pile is improved.

[0015] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each positioning rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the reinforcement plate.

[0016] Through the above solution, the positioning rod is restricted to prevent the positioning rod from sliding and deviating.

[0017] Furthermore, the outer circumferential surface of each of the ground cones is fixedly connected to two limit blocks, and the outer surface of each of the limit blocks is slidably connected to the reinforcement plate through a hollow groove opened inside the reinforcement plate.

[0018] Through the above scheme, the ground cone is restricted to prevent the ground cone from rotating along with the positioning rod, so that the ground cone is always moved longitudinally.

[0019] Furthermore, the reinforcement plate is made of a hard alloy material, and the outer surface of the reinforcement plate is coated with an anti-rust coating.

[0020] Through the above scheme, the reinforcement plate with a harder texture can further improve the bearing capacity of the precast piles, and the anti-rust coating can protect the reinforcement plate to prevent the reinforcement plate from being easily rusted.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The bored backfill precast pile periphery reinforcement structure provides a reinforcement plate on the outer surface of the pile body and uses mounting rods and nuts to connect and fix the reinforcement plate to the pile body, thereby enabling the pile body to be effectively supported and reinforced, thereby increasing the bearing capacity of the pile body, improving the pile body's ability to resist lateral displacement, and improving the safety and stability of the project, and solving the problem that the stability of the precast piles will be affected by the foundation itself. If the foundation soil is not good, the bearing capacity and resistance to lateral displacement of the precast piles will be reduced, affecting the safety and stability of the project.

The interior of the reinforcement plates 3 is slidably connected to the outer circumferential surface of the installation rods 4, and the outer circumferential surface of each installation rod 4 is threadedly connected with a nut 5.

[0031] See also Figure 1 , Figure 2 and Figure 3A connecting groove 6 is provided at the top of each reinforcement plate 3, and a connecting plate 7 is provided above the foundation 1. The outer surfaces of the connecting plates 7 are slidably connected to the reinforcement plates 3 through the connecting grooves 6. The four reinforcement plates 3 are connected into a whole through the connecting grooves 6 and the connecting plates 7, thereby improving the overall stability of the reinforcement structure.

[0032] See also Figure 1 and Figure 2 Each reinforcement plate 3 is threadedly connected to two bolts 8, and the outer circumferential surface of the bolts 8 is slidably inserted into the interior of the connecting plate 7. The reinforcement plate 3 and the connecting plate 7 are connected and fixed by the bolts 8, further improving the overall stability of the reinforcement structure.

[0033] See also Figure 1 , Figure 2 and Figure 4 Each reinforcement plate 3 has four positioning rods 9 rotatably inserted inside, and the outer circumferential surface of each positioning rod 9 is threadedly connected with a ground cone 10. The positioning rods 9 can be rotated to drive the ground cone 10 to move downward, prompting the ground cone 10 to be inserted into the foundation 1, thereby increasing the gripping ability of the reinforcement plate 3 and thereby improving the stability of the reinforcement structure.

[0034] See also Figure 1 and Figure 3 The outer surface of each reinforcement plate 3 is fixedly connected with four support plates 11, and each support plate 11 has a triangular structure, which supports and reinforces the reinforcement plate 3, increases the overall bearing capacity of the reinforcement plate 3, and thus improves the stability of the precast pile.

[0035] See also Figure 4 The outer circumference of each positioning rod 9 is fixedly sleeved with a limiting ring 12, and the outer circumference of the limiting ring 12 is rotatably connected to the inside of the reinforcing plate 3 to limit the positioning rod 9 and prevent the positioning rod 9 from sliding and deviating.

[0036] See also Figure 4 The outer circumferential surface of each ground cone 10 is fixedly connected to two limit blocks 13, and the outer surface of each limit block 13 is slidably connected to the reinforcement plate 3 through a hollow groove opened inside the reinforcement plate 3, so as to limit the ground cone 10 and prevent the ground cone 10 from rotating with the positioning rod 9, so as to enable the ground cone 10 to always move longitudinally.

The harder reinforcement plate 3 can further improve the bearing capacity of the precast pile, and the anti-rust coating can protect the reinforcement plate 3 and prevent the reinforcement plate 3 from being easily corroded.

If the soil quality of the foundation 1 is poor, the bearing capacity and lateral displacement resistance of the precast pile will be reduced, affecting the safety and stability of the project.

[0039] It should be noted that when the pile body 2 is a circular structure, it is only necessary to thicken one end of the reinforcement plate 3 close to the circular pile body 2, and set the contact surface between the reinforcement plate 3 and the circular pile body 2 to an arc surface that matches the circular pile body 2. The rest of the structure remains unchanged, and the reinforcement operation of the circular pile body 2 can be completed.

[0040] The working principle of the above embodiment is:

[0041] When the prefabricated piles need to be reinforced, four reinforcement plates 3 are installed on the sides of the pile body 2 through the mounting rods 4, and then the reinforcement plates 3 are fixed with nuts 5, and then the connecting plates 7 are installed into the connecting grooves 6, and the connecting plates 7 and the four reinforcement plates 3 are connected and fixed in turn with bolts 8, so that the four reinforcement plates 3 are fixedly connected into a whole, and finally the positioning rods 9 are rotated to drive the ground cones 10 to move downward, so that the ground cones 10 are inserted into the foundation 1, thereby increasing the gripping ability of the reinforcement plates 3, and thus improving the stability of the reinforced structure. The installed reinforcement plates 3 can support and reinforce the pile body 2, increase the bearing capacity of the pile body 2, improve the anti-lateral displacement ability of the pile body 2, and improve the safety and stability of the project.
