Description

Technical Field

[0001] This utility model relates to the technical field of micro steel pipe cast-in-place pile reinforcement equipment, specifically a micro steel pipe cast-in-place pile reinforcement device for old and inefficient foundations. Background Technology

[0002] To improve the support strength and service life of micro-steel pipe piles in old and inefficient foundations, reinforcement work is often required. Utility model patent application number CN202320110575.3 discloses a reinforcement structure for controlling large local deformations in foundation pits. It employs reinforcement measures such as external sealing and internal drainage, soil backfilling, and anchor cables. During excavation, it effectively and promptly reinforces the soil between the new foundation pit and existing buildings, thereby preventing settlement and deformation damage to old buildings and horizontal deformation damage to the new foundation pit caused by slope instability within the pit. This effectively ensures the foundation's stability even under severe wind conditions. To ensure safe and efficient foundation pit construction under dangerous conditions, targeted risk control and reinforcement are adopted for the slopes inside the pit and the perimeter wall of the community, resulting in excellent risk control effects. According to its publicly available technical solutions, existing equipment for reinforcing micro-steel pipe piles often requires the excavation of larger foundation pits around the micro-steel pipe piles. Due to the influence of the buildings above, excavation is inconvenient and can easily affect the building structure. On the other hand, after completing the reinforcement of old and inefficient foundations with micro-steel pipe piles, the reinforcement mechanism is prone to loosening due to vibration and other factors, which is not conducive to ensuring the reinforcement strength.

[0003] Therefore, how to design a micro-steel pipe pile reinforcement device for old and inefficient foundations has become a problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a micro steel pipe cast-in-place pile reinforcement device for old and inefficient foundations, so as to solve the problems mentioned in the background art. This utility model is reasonably designed, convenient to use, and suitable for reinforcement of old foundations with micro steel pipe cast-in-place piles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a micro steel pipe cast-in-place pile reinforcement device for old and inefficient foundations, comprising a reinforcement body, splicing components installed on both sides of the reinforcement body, the splicing components including connectors and joints, insertion components installed on the connectors and joints, the insertion components including insert plates and slots, limiting components installed on the insert plates and joints, the limiting components including slots and latches, a locking component installed inside the slots, the locking component including a locking pin and a spring, and a reinforcement component installed on the joints, the reinforcement component including an extension plate and a stop.

[0006] Furthermore, the connector is integrally formed on one side of the reinforcing body, and the joint is integrally formed on the other side of the reinforcing body.

[0007] Furthermore, the number of the reinforcing bodies is three, and the three reinforcing bodies are connected end to end in a ring through connectors and joints.

[0008] Furthermore, the insert plate is integrally formed on the connector, the slot is opened on the inside of the connector, and the insert plate and the slot cooperate with each other.

[0009] Furthermore, the slot is located on the inner side of the insert plate, and the bayonet opening is located on one side of the connector, with the bayonet opening communicating with the slot.

[0010] Furthermore, the outer side of the locking pin is engaged with the inner wall of the slot, one end of the locking pin is connected to the inner wall of the slot via a spring, and the other end of the locking pin extends to the inner side of the slot.

[0011] Furthermore, a through hole is provided on the other side of the connector, and the through hole is connected to the inner side of the slot.

[0012] Furthermore, the extension plate is integrally formed on the other side of the joint, the baffle is opened on the inner side of the extension plate, and the baffle is evenly distributed on the extension plate.

[0013] Beneficial effects: 1. When using this micro steel pipe cast-in-place pile reinforcement device for old and inefficient foundations, a slightly larger foundation pit (the diameter of the foundation pit is slightly larger than the diameter of the reinforcement body) is excavated around the micro steel pipe cast-in-place pile of the old and inefficient foundation. Then, three reinforcement bodies are inserted into the inside of the foundation pit, and the insert plates on the three reinforcement bodies are inserted into the inside of the adjacent slots one by one. The locking pin is first squeezed into the inside of the slot by the inner wall of the slot. Then, when the insert plate is fully inserted into the inside of the slot, the spring pushes the locking pin into the inside of the locking opening, so that the three reinforcement bodies are connected end to end in a ring. This can effectively reduce the amount of excavated soil, reduce the construction intensity, and at the same time reduce the impact on the above buildings, ensuring the safety of the above buildings.

[0014] 2. In use, the micro-steel pipe cast-in-place pile reinforcement device for old and inefficient foundations has a locking pin that is secured to the inside of the slot by the spring force, effectively preventing loosening of the connection. Concrete is then poured into the inside of the reinforcement body. After the concrete solidifies, the reinforcement body and the concrete improve the support strength and service life of the micro-steel pipe cast-in-place pile. The concrete flows through the through hole to the inside of the slot on the inside of the reinforcement body, and fills the gap between the stop and the extension plate and the connector. After the concrete is completely solidified, on the one hand, the concrete limits the locking pin to prevent loosening of the reinforcement body, and on the other hand, the concrete locks the extension plate and the connector, effectively ensuring the connection strength of the three reinforcement bodies, thereby ensuring the reinforcement strength of the micro-steel pipe cast-in-place pile for old and inefficient foundations.

[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] Please see Figures 1 to 3This utility model provides a technical solution: a micro-steel pipe cast-in-place pile reinforcement device for old and inefficient foundations, comprising a reinforcement body 1, splicing components installed on both sides of the reinforcement body 1, each splicing component including a connector 2 and a joint 3, and insertion components installed on the connector 2 and joint 3, each insertion component including a plate 4 and a slot 5, and limiting components installed on the plate 4 and joint 3, each limiting component including a groove 6 and a latch 7, a locking component installed inside the groove 6, the locking component including a pin 8 and a spring 9, and a reinforcement component installed on the joint 3, the reinforcement component including an extension plate 11 and a stop 12, the connector 2 being integrally formed on one side of the reinforcement body 1, and the joint 3 being integrally formed on the other side of the reinforcement body 1. The number of reinforcement bodies 1 is 3. The three reinforcement bodies 1 are connected end to end in a ring by connectors 2 and joints 3. In use, a slightly larger foundation pit (the diameter of the foundation pit is slightly larger than the diameter of the reinforcement body 1) is excavated around the micro steel pipe cast-in-place piles of old and inefficient foundations. The three reinforcement bodies 1 are then inserted into the inside of the foundation pit, and the insert plates 4 on the three reinforcement bodies 1 are inserted into the inside of the adjacent slots 5 one by one. The locking pins 8 are first squeezed into the inside of the slot 6 by the inner wall of the slot 5. After the insert plates 4 are fully inserted into the inside of the slot 5, the spring 9 pushes the locking pins 8 into the inside of the locking opening 7, so that the three reinforcement bodies 1 are connected end to end in a ring. This can effectively reduce the amount of excavated soil, reduce the construction intensity, and at the same time reduce the impact on the above buildings, ensuring the safety of the above buildings.

[0022] In this embodiment, the insert plate 4 is integrally formed on the connector 2. The slot 5 is opened on the inner side of the connector 3, and the insert plate 4 and the slot 5 cooperate. The slot 6 is opened on the inner side of the insert plate 4. The latch 7 is opened on one side of the connector 3 and is connected to the slot 6. The outer side of the latch 8 is engaged with the inner wall of the slot 6. One end of the latch 8 is connected to the inner wall of the slot 6 through a spring 9, and the other end of the latch 8 extends to the inner side of the latch 7. A through hole 10 is opened on the other side of the connector 3 and is connected to the inner side of the slot 6. The extension plate 11 is integrally formed on the other side of the connector 3. The baffle 12 is opened on the inner side of the extension plate 11 and is evenly distributed on the extension plate 11. In use, the latch 8 springs... The spring 9 is clamped tightly inside the bayonet 7 under its elastic force, effectively preventing the connection from becoming loose. Then, concrete is poured into the inside of the reinforcing body 1. After the concrete solidifies, the support strength and service life of the micro steel pipe cast-in-place pile are improved by the reinforcing body and the concrete. The concrete flows into the inside of the slot 6 through the through hole 10 inside the reinforcing body 1, and fills the gap between the stop 12 and the extension plate 11 and the connector 2. After the concrete is completely solidified, on the one hand, the concrete limits the locking pin 8 to prevent the connection of the reinforcing body 1 from becoming loose. On the other hand, the concrete locks the extension plate 11 and the connector 2, effectively ensuring the connection strength of the three reinforcing bodies 1, thereby ensuring the reinforcement strength of the micro steel pipe cast-in-place pile for old and inefficient foundations.

[0023] When using this micro-steel pipe cast-in-place pile reinforcement device for old and inefficient foundations, a slightly larger foundation pit (the diameter of the pit is slightly larger than the diameter of the reinforcement body 1) is excavated around the micro-steel pipe cast-in-place pile in the old and inefficient foundation. Then, three reinforcement bodies 1 are inserted into the inside of the foundation pit, and the insert plates 4 on the three reinforcement bodies 1 are inserted one by one into the inside of the adjacent slots 5. The locking pin 8 is first pressed into the inside of the slot 6 by the inner wall of the slot 5. Then, when the insert plate 4 is fully inserted into the inside of the slot 5, the spring 9 pushes the locking pin 8 into the inside of the locking opening 7, thus connecting the three reinforcement bodies 1 end to end in a ring. This can effectively reduce the amount of excavated soil, reduce construction intensity, and at the same time reduce the impact on the above buildings, ensuring the safety of the above buildings. Under the elastic force of the spring 9, the locking pin 8... The connection is secured to the inside of the clamp 7 to effectively prevent loosening. Then, concrete is poured into the inside of the reinforcement body 1. After the concrete solidifies, the reinforcement body and concrete improve the support strength and service life of the micro steel pipe pile. The concrete flows through the through hole 10 to the inside of the groove 6 inside the reinforcement body 1, and fills the gap between the stop 12 and the extension plate 11 and the connector 2. After the concrete is completely solidified, on the one hand, the concrete limits the clamp 8 to prevent loosening of the reinforcement body 1. On the other hand, the concrete locks the extension plate 11 and the connector 2, effectively ensuring the connection strength of the three reinforcement bodies 1, thereby ensuring the reinforcement strength of the micro steel pipe pile for old and inefficient foundations.
