Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a construction device for a single-pile foundation conversion pile-bucket combination foundation. Background Technology

[0002] The construction of a monopile foundation conversion pile-bucket combination foundation involves combining a monopile foundation with a pile-bucket combination, which can effectively enhance the stability and bearing capacity of the foundation, while providing greater flexibility to adapt to different geological conditions and design requirements.

[0003] In the construction of existing monopile foundation conversion pile-bucket combination foundations, the pile bucket and monopile are usually fixed to the construction ground, so that the monopile extends downward into the foundation to provide support. However, due to environmental loads or construction errors, relative displacement may occur between the pile bucket and monopile, which may affect the stability and durability of the overall structure.

[0004] Therefore, it is necessary to design a single-pile foundation conversion pile-bucket combined foundation construction device that can limit the relative displacement between the pile bucket and the single pile during combined installation, thereby enhancing the structural stability. Utility Model Content

[0005] To overcome the shortcomings of existing monopile foundation conversion pile-bucket combined foundation construction, where relative displacement between the pile bucket and the monopile may occur due to environmental loads or construction errors, thus affecting the stability and durability of the overall structure, this utility model provides a monopile foundation conversion pile-bucket combined foundation construction device that can limit the relative displacement between the pile bucket and the monopile during combined installation, thereby enhancing the structural stability.

[0006] A construction device for a single-pile foundation conversion pile bucket combined foundation includes a pile bucket, sliding sleeves, extension rods, nuts, pressure blocks, second springs, second limiting blocks, and single piles. The pile bucket has two sections, front and rear. Sliding sleeves are connected to both sides of the pile bucket, and extension rods are slidably connected to each sliding sleeve. Nuts are threadedly connected to the upper parts of each extension rod, and the nuts contact the adjacent sliding sleeves. Pressure blocks are slidably connected to the front, rear, left, and right sides of the pile bucket via damping. Second limiting blocks are also slidably connected to the front, rear, left, and right sides of the pile bucket, and are located below adjacent pressure blocks. Second springs connect each second limiting block to the adjacent pile bucket. A single pile is sleeved in the middle of each pile bucket, and the second limiting blocks and pressure blocks are engaged with the adjacent single piles.

[0007] Furthermore, the reinforcement assembly includes a collar, a first spring, a first limiting block, and a secondary stake. The outer side of the extension rod is connected to a collar, and the inner side of the collar is slidably connected to a first limiting block. The first limiting block is connected to the adjacent collar with a first spring. The collar is fitted with a secondary stake, and the first limiting block is engaged with the adjacent secondary stake.

[0008] Furthermore, all the first limiting blocks are wedge-shaped structures.

[0009] Furthermore, limit grooves are opened on the upper part of each auxiliary pile.

[0010] Furthermore, it also includes connecting sleeves, connecting rods, and screws. Connecting sleeves are connected to both the front and rear sides of the pile bucket. Screws are threadedly connected to the upper and left sides of the connecting sleeves. Connecting rods are detachably connected between the connecting sleeves on the adjacent sides of the pile bucket via screws.

[0011] Furthermore, all connecting sleeves are U-shaped.

[0012] The beneficial effects are as follows: 1. By inserting a single pile into the pile bucket, the single pile will squeeze the second limiting block during its downward movement, causing the second limiting block to move outward. As the single pile continues to move downward, the second limiting block will engage with the single pile. By using the pressure block to limit the second limiting block, the system can limit the distance between the pile bucket and the single pile during assembly, preventing relative displacement between the two and enhancing structural stability.

[0013] 2. This utility model inserts the secondary pile into the collar. When the secondary pile moves downward, it squeezes the first limiting block to move outward. The first spring is compressed and contracts. After the secondary pile moves downward to the designated position, the first spring returns to its original state, driving the first limiting block to move inward and engage with the secondary pile, so that the secondary pile is inserted into the ground. This achieves the effect of strengthening and locking the secondary pile, thereby improving the overall stability. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A construction device for a single-pile foundation conversion pile-bucket combination foundation, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a pile barrel 1, a sliding sleeve 2, an extension rod 3, a nut 4, a pressure block 9, a second spring 10, a second limiting block 11, and a single pile 12. The pile barrel 1 has two sections, front and rear. Sliding sleeves 2 are connected to both sides of the pile barrel 1. Extension rods 3 are slidably connected to the sliding sleeves 2. Nuts 4 are threadedly connected to the upper part of the extension rods 3. Nuts 4 are in contact with the adjacent sliding sleeves 2. Pressure blocks 9 are slidably connected to the four sections of the pile barrel 1 through damping. Second limiting blocks 11 are also slidably connected to the four sections of the pile barrel 1. The second limiting blocks 11 are located below the adjacent pressure blocks 9. A second spring 10 is connected between the second limiting blocks 11 and the adjacent pile barrel 1. A single pile 12 is sleeved in the middle of the pile barrel 1. The second limiting blocks 11 and pressure blocks 9 are engaged with the adjacent single pile 12.

[0022] like Figure 1 and Figure 2 As shown, the reinforcement assembly includes a collar 5, a first spring 6, a first limiting block 7, and a secondary pile 8. The extension rod 3 is connected to the outer side of the collar 5. The collar 5 is slidably connected to the first limiting block 7. The first limiting block 7 is wedge-shaped. The first limiting block 7 is connected to the adjacent collar 5 by a first spring 6. The collar 5 is fitted with a secondary pile 8. The upper part of the secondary pile 8 is opened with a limiting groove to facilitate the limiting with the first limiting block 7. The first limiting block 7 is engaged with the adjacent secondary pile 8.

[0023] like Figure 1 and Figure 3 As shown, it also includes a connecting sleeve 13, a connecting rod 14 and a screw 15. The front and rear sides of the pile bucket 1 are connected with connecting sleeves 13. The connecting sleeves 13 are all U-shaped structures to facilitate docking. The upper and left sides of the connecting sleeves 13 are threaded with screws 15. The connecting sleeves 13 on the adjacent sides of the pile bucket 1 are detachably connected with the connecting rod 14 by screws 15.

[0024] When using this device, first place the pile bucket 1 in the construction area, then insert the connecting rod 14 between the connecting sleeves 13, and lock the connecting rod 14 and the connecting sleeves 13 with screws 15. The connecting sleeves 13 connect the pile buckets 1 to enhance stability. Next, fix the pile bucket 1 to the construction site, and then insert the single pile 12 into the pile bucket 1. As the single pile 12 moves downward, it will squeeze the second limiting block 11, causing the second limiting block 11 to move outward on the pile bucket 1. The second spring 10 is compressed and contracts. When the single pile 12 moves downward to a certain position and contacts the pressure block 9, it will cause the pressure block 9 to move downward. When the pressure block 9 moves downward to its limit, the second spring 10 returns to its original state, causing the second limiting block 11 to move inward, so that the second limiting block 10... Positioning block 11 engages with single pile 12. The second limiting block 11 is limited by pressure block 9, thus limiting the relative displacement between pile barrel 1 and single pile 12 during assembly, enhancing structural stability. Then, extension rod 3 extends outward on sliding sleeve 2, and nut 4 is tightened to contact sliding sleeve 2. Sub-pile 8 is then inserted into collar 5. As sub-pile 8 moves downward, it compresses the first limiting block 7, causing the first spring 6 to contract. After sub-pile 8 moves to the designated position, the first spring 6 returns to its original position, driving the first limiting block 7 to move inward and engage with sub-pile 8, allowing sub-pile 8 to be inserted into the ground. This provides reinforcement and locks sub-pile 8, improving overall stability.
