Description

Technical Field

[0001] This utility model relates to the field of concrete pipe pile technology, and in particular to a concrete pipe pile made of recycled aggregate. Background Technology

[0002] Recycled aggregate refers to aggregate materials made from waste concrete, broken bricks, and old cement pavement materials obtained from construction waste through processes such as crushing and screening. It can replace natural aggregates in applications such as subgrade soil improvement, mortar preparation, and recycled concrete, such as reinforced concrete pipe piles made from recycled aggregate. Chinese patent document CN215669469U discloses a concrete pipe pile, comprising a pile body, a top plate, and a bottom plate. The top plate is installed on the top surface of the pile body, and the bottom plate is installed on the bottom surface of the pile body. An insertion groove is formed on the top surface of the top plate, and an inner groove is formed on the inner wall of the insertion groove. A locking block is slidably inserted into the inner groove, and one end of the locking block is inclined. By using the top and bottom plates, during pile splicing, the insertion ring on the bottom surface of the bottom plate of the upper pile body is directly inserted into the insertion groove on the top surface of the top plate. During insertion, the insertion ring presses against the inclined surface of the locking block, pushing the locking block into the inner groove. A spring compresses, and when the insertion ring is fully inserted into the insertion groove, the locking block aligns with the locking groove. The spring rebounds, pushing the locking block into the locking groove, thus completing the self-locking connection. This eliminates the hassle of on-site welding and improves construction efficiency.

[0003] After the two sets of concrete pipe piles are self-locked together by springs and plug rings, if damage is found in one of the sets of concrete pipe piles, the plug ring cannot be removed from the plug groove, making it inconvenient to disassemble and replace the concrete pipe pile.

[0017] Please see Figure 1-5This utility model provides a technical solution: a concrete pipe pile with recycled aggregate, including a lower pipe pile 1, an upper pipe pile 2 at the top of the lower pipe pile 1, a connecting sleeve 3 fixedly installed on the outer wall of the lower pipe pile 1, the connecting sleeve 3 being fitted onto the bottom of the upper pipe pile 2, a fixing groove 4 being opened at the top of the connecting sleeve 3, and also including a locking component disposed inside the fixing groove 4, the locking component being used to install the upper pipe pile 2 onto the top of the lower pipe pile 1, and a sealing ring 14 disposed inside the connecting sleeve 3, the sealing ring 14 being used to increase the sealing between the connecting sleeve 3 and the upper pipe pile 2.

[0018] Furthermore, the engaging assembly includes a claw 7, a spring A9, a shaft pin 10, and a spring B11. The claw 7 is located inside the fixing groove 4, and mounting holes 8 are provided on both the front and rear sides of the claw 7. There are two springs A9, each placed inside one of the mounting holes 8. There are two shaft pins 10, each slidably mounted inside one of the mounting holes 8. The spring B11 is fixedly mounted on one outer wall of the claw 7. When the upper pipe pile 2 is inserted into the inner side of the connecting sleeve 3, the pushing action of the spring B11 on the claw 7 causes one end of the claw 7 to pass through the connecting opening. Inserted into the slot 12, the upper pipe pile 2 can be self-locked into the connecting sleeve 3, enabling quick connection between the upper pipe pile 2 and the lower pipe pile 1. By manually pushing the claw 7 through the through hole 5, the claw 7 can be removed from the slot 12, thereby separating the upper pipe pile 2 and the lower pipe pile 1. This not only achieves quick self-locking connection between the upper and lower pipe piles, eliminating the need for on-site welding and greatly improving construction efficiency, but also allows for easy release of the locking state by manually pushing the claw through the through hole, solving the problem of difficulty in disassembling and replacing traditional pipe piles after connection.

[0019] Furthermore, shaft holes 6 are provided on both the front and rear sides of the fixing groove 4, and two shaft pins 10 are inserted into the inner side of the shaft holes 6.

The base layer 101 is recycled aggregate concrete, the insulation layer 102 is rock wool, and the waterproof layer 103 is waterproof coating. The upper pipe pile 2 and the lower pipe pile 1 are made of the same material. The pipe pile adopts a recycled aggregate concrete base layer, combined with a rock wool insulation layer and a waterproof coating layer, which not only realizes the resource utilization of construction waste, but also improves the insulation and waterproof performance of the pipe pile, combining economy and functionality.

[0025] Working principle: Insert the upper pipe pile 2 into the inner side of the connecting sleeve 3. Due to the push of the spring B11 on the claw 7, one end of the claw 7 passes through the connecting port and is inserted into the slot 12, which can lock the upper pipe pile 2 into the connecting sleeve 3, and realize the quick docking of the upper pipe pile 2 and the lower pipe pile 1. When the lower pipe pile 1 or the upper pipe pile 2 is found to be damaged, remove the dust cover 15 from the outside of the connecting sleeve 3, and manually push the claw 7 through the through hole 5 to remove the claw 7 from the slot 12, thereby separating the upper pipe pile 2 and the lower pipe pile 1, and replacing the damaged concrete pipe pile.
