Description

Technical Field

[0001] This utility model is a diagonal bracing installation device for building foundation pit support, belonging to the field of construction. Background Technology

[0002] With the development of national economic construction, the construction of underground spaces is becoming increasingly frequent, and the construction technology of foundation pit support systems, which serve to support, reinforce, and protect underground spaces, has also made significant progress. In recent years, to avoid exceeding the red line of building projects, relevant policies have prohibited the use of soil anchors for deep foundation pits in soft soil; while the support method using retaining piles plus horizontal inward bracing is relatively expensive; therefore, the combined support method of retaining piles, capping beams, and inclined bracing piles within the foundation pit has gained increasingly widespread application. The inclined bracing pile consists of a combined inclined pile extending below the foundation pit floor and a steel pipe inclined brace located above the foundation pit floor; the upper end of the steel pipe inclined brace abuts against the capping beam, and the lower end of the steel pipe inclined brace is supported on the upper end of the combined inclined pile; the combined inclined pile consists of a central precast concrete square pile and an outer cement-soil pile.

[0003] However, when constructing grouting steel pipe diagonal supports, a pulling machine is needed to insert the steel pipe diagonally into the soil. However, due to the long height and heavy weight of the steel pipe, when placing the steel pipe at an angle and aligning it with the insertion position, the insertion angle and position of the steel pipe are mainly observed and controlled by the naked eye, which leads to a large deviation when the steel pipe is inserted into the soil, reducing the quality of the steel diagonal support. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a building foundation pit retaining diagonal bracing installation device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A building foundation pit retaining diagonal bracing installation device is characterized by comprising a mixing pile inserted into the soil layer, the top of the mixing pile and the top surface of the soil layer being filled with concrete layers, an installation component being slidably mounted on the concrete layer, the installation component comprising a sliding member and an angle adjusting member mounted on the sliding member, the angle adjusting member comprising a flipping seat, a fixed steel pipe sleeve being fixedly mounted on the top of the flipping seat, a threaded screw hole being opened on the sliding member, a threaded rod being threaded into the threaded screw hole, a threaded cylinder being threaded into the other end of the threaded rod, a positioning sleeve being fixedly mounted on the threaded cylinder, and reinforcing steel being cast and formed on the mixing pile.

[0007] Furthermore, both the positioning sleeve and the fixing steel pipe sleeve are integral cylinders composed of two semi-cylinders, and the semi-cylinders are connected by metal hinges. Multiple fixing plates are fixed on each semi-cylinder, and the fixing plates are fixed together by screws.

[0008] Furthermore, both the positioning sleeve and the fixing steel pipe sleeve are threaded with multiple locking screws, and the sliding component includes a sliding seat, with universal wheels provided at the four corners of the bottom end of the sliding seat.

[0009] Furthermore, a threaded insertion hole is provided on the sliding seat, and the angle adjustment component includes a slide table that is slidably disposed inside the sliding seat, with a flip seat fixed to the top of the slide table.

[0010] Furthermore, a first slide rod and a second slide rod are fixedly provided at both ends of the slide table, and a slide groove matching the first slide rod and the second slide rod is opened on the outer surface of the slide seat. A flip groove is also opened on the outer surface of the slide seat.

[0011] Furthermore, a motor plate is fixedly provided on one side of the sliding seat, and a drive motor and a reducer are fixedly provided on the motor plate. The drive motor is connected to the reducer, and an eccentric plate is provided on the output end rod of the reducer. A fixed round rod is fixedly provided on one end of the eccentric plate, and a movable sleeve is movably sleeved on the outer surface of the fixed round rod.

[0012] Furthermore, a connecting plate is fixedly provided on the movable sleeve, and a secondary movable sleeve is fixedly provided at the other end of the connecting plate. A secondary fixed round rod is fixedly provided on the slide table, and the secondary movable sleeve is movably fitted on the secondary fixed round rod.

[0013] Furthermore, both the auxiliary fixed round rod and the outer surface of the fixed round rod are fixed with limiting rings, and the inner surfaces of the movable sleeve and the auxiliary movable sleeve are provided with limiting grooves that match the limiting rings.

[0014] The beneficial effects of this utility model are:

[0015] After the mixing pile construction is completed, a concrete layer is poured on the surface of the mixing pile and the soil layer. The mixing pile increases the stability and firmness of the concrete layer, avoids rapid settlement of the concrete layer during the insertion of the steel pipe, and prevents the steel pipe from being misaligned in the soil layer.

[0016] The sliding component drives the tilting seat to move, causing it to move towards the mixing pile. Once the installation component is in the appropriate position, the tilting seat is tilted by the angle adjustment component, thus causing the fixed steel pipe sleeve to tilt. Since the steel pipe to be used is inserted into the fixed steel pipe sleeve, the steel pipe is tilted. During the construction of the steel pipe diagonal support, a driving and pulling machine is used to insert the steel pipe diagonally into the soil. Furthermore, the tilt angle can be adjusted in advance during insertion, so that the steel pipe is tilted and aligned with the insertion position, reducing the large deviation when the steel pipe is inserted into the soil and reducing the quality of the steel diagonal support.

[0017] By screwing the threaded rod into the threaded hole, and then placing the positioning sleeve inside one of the reinforcing steels, the threaded rod is slowly rotated until the other end of the threaded rod is also screwed into the threaded sleeve. Thus, the installation components, threaded rod, threaded sleeve, positioning sleeve, and reinforcing steel are connected together to ensure the positioning of the installation components after they are moved. This further prevents the steel pipe from shifting into the soil during the process of diagonal bracing and retaining the structure, which is when the steel pipe is inserted into the soil, and greatly improves the quality of the steel diagonal bracing.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a building foundation pit retaining diagonal bracing installation device, including a mixing pile 2 inserted into the soil layer 1. The top of the mixing pile 2 and the top surface of the soil layer 1 are both filled with concrete layers 3. An installation component is slidably installed on the concrete layer 3. The installation component includes a sliding part and an angle adjustment part set on the sliding part. The angle adjustment part includes a flip seat 4. A fixed steel pipe sleeve 5 is fixedly installed on the top of the flip seat 4. A threaded screw hole 6 is opened on the sliding part. A threaded rod 7 is threaded into the threaded screw hole 6. A threaded cylinder 8 is threaded into the other end of the threaded rod 7. A positioning sleeve 9 is fixedly installed on the threaded cylinder 8. A reinforcing steel 10 is cast and formed on the mixing pile 2.

[0026] See Figure 2 Both the positioning sleeve 9 and the fixing steel pipe sleeve 5 are integral cylinders composed of two semi-cylinders connected by metal hinges. Multiple fixing plates 11 are fixed to each semi-cylinder, and these plates are secured with screws. Multiple locking screws 12 are threaded into both the positioning sleeve 9 and the fixing steel pipe sleeve 5. The sliding component includes a sliding seat 13, with casters 14 at each of the four corners of its bottom end. This facilitates movement of the assembly. The steel pipe is inserted into the fixed steel pipe sleeve 5, whose internal dimensions match the steel pipe dimensions. Then, the locking screw 12 is screwed into the fixed steel pipe sleeve 5, and the locking screw 12 abuts against the steel pipe inside the fixed steel pipe sleeve 5, fixing the steel pipe and preventing it from slipping inside the fixed steel pipe sleeve 5 during tilt adjustment. The positioning sleeve 9 is fitted onto the reinforcing steel 10 and locked in the same way by the locking screw 12. The internal dimensions of the positioning sleeve 9 are adapted to the dimensions of the reinforcing steel 10, which is the reinforcing bar. This ensures the positioning of the installation components after movement, further preventing displacement of the steel pipe during the diagonal bracing process, i.e., during the insertion of the steel pipe into the soil layer 1, greatly improving the quality of the steel diagonal bracing.

[0027] See Figure 2-3A threaded insertion hole 6 is provided on the sliding seat 13. The angle adjustment component includes a slide table 15 slidably disposed inside the sliding seat 13. A flip seat 4 is fixed to the top of the slide table 15. A first slide rod 16 and a second slide rod 17 are fixedly provided at both ends of the slide table 15. A groove 18 matching the first slide rod 16 and the second slide rod 17 is provided on the outer surface of the sliding seat 13. A flip groove 19 is also provided on the outer surface of the sliding seat 13. A motor plate 20 is fixedly provided on one side of the sliding seat 13. A drive motor 21 and a reducer 22 are fixedly provided on the motor plate 20. The drive motor 21 is connected to the reducer 22 and reduces the speed. The output end rod of the machine 22 is provided with an eccentric plate 23. One end of the eccentric plate 23 is fixedly provided with a fixed round rod 24. The outer surface of the fixed round rod 24 is movably fitted with a movable sleeve 25. A connecting plate 26 is fixedly provided on the movable sleeve 25. The other end of the connecting plate 26 is fixedly provided with a secondary movable sleeve 30. A secondary fixed round rod 27 is fixedly provided on the slide table 15. The secondary movable sleeve 30 is movably fitted on the secondary fixed round rod 27. The outer surfaces of the secondary fixed round rod 27 and the fixed round rod 24 are both fixedly provided with limiting rings 28. The inner surfaces of the movable sleeve 25 and the secondary movable sleeve 30 are both provided with limiting grooves 29 that match the limiting rings 28. Turning on the drive motor causes its reducer 22 to drive the eccentric plate 23 to rotate. The eccentric plate 23 then drives the fixed round rod 24 to rotate, and the movable sleeve 25 fitted on the outer surface of the fixed round rod 24 also rotates. This causes the connecting plate 26 and the auxiliary movable sleeve 30 to move. During this movement, the slide table 15 moves inside the sliding seat 13, allowing for reciprocating movement. As the slide table 15 moves, the first slide rod 16 and the second slide rod 17 move within the slide groove 18. When the second slide rod 17 reaches the rightmost end of the slide groove 18, the slide table 15 can no longer move. When the eccentric plate 23 moves within 13, it has not yet completed a full rotation. As the eccentric plate 23 continues to rotate, it can drive the second slide rod 17 to rotate in place at the rightmost end of the slide groove 18. At this time, the first slide rod 16 moves and flips into the tilting groove 19. The first slide rod 16 moves within the tilting groove 19, thus driving the slide table 15 to rotate with the second slide rod 17 as the turning point. This causes the slide table 15 to rotate, ultimately adjusting the tilt of the fixed steel pipe sleeve 5. The speed reducer ensures that the tilt adjustment movement is slow, making it easy to adjust to a suitable tilt angle.

[0028] During use, after the construction of the mixing pile 2 is completed, a concrete layer 3 is poured on the surface of the mixing pile 2 and the soil layer 1. The mixing pile 2 increases the stability and firmness of the concrete layer 3, preventing rapid settlement of the concrete layer during the insertion of the steel pipe and preventing misalignment of the steel pipe in the soil layer 1. The sliding component drives the flipping seat 4 to move, so that the flipping seat 4 moves towards the mixing pile 2. The installation component moves to the appropriate position, and the angle adjustment component drives the flipping seat 4 to flip, thus causing the fixed steel pipe sleeve 5 to tilt. Since the steel pipe to be used is inserted into the fixed steel pipe sleeve 5, the steel pipe is tilted. During the construction of the steel pipe inclined support, a driving and pulling machine is used to insert the steel pipe obliquely into the soil, and during insertion... This allows for pre-adjustment of the tilt angle, ensuring the steel pipe is tilted and aligned with the insertion position. This reduces significant deviations when the steel pipe is inserted into the soil, thus improving the quality of the steel bracing. The threaded rod 7 is screwed into the threaded insertion hole 6, and the positioning sleeve 9 is then fitted into one of the reinforcing steels 10. The threaded rod 7 is then slowly rotated until its other end is also threaded into the threaded cylinder 8. Therefore, the installation assembly, threaded rod 7, threaded cylinder 8, positioning sleeve 9, and reinforcing steel 10 are connected together, ensuring the positioning of the installation assembly after movement. This further prevents the steel pipe from shifting during the bracing process, specifically during the insertion of the steel pipe into the soil layer 1, significantly improving the quality of the steel bracing once again.

[0029] In subsequent work, a driving and pulling machine was used to drive the steel pipe into the soil. The driving and pulling machine is existing technology and will not be described in detail here. All electrical components used are connected to an external power source. The circuits, electrical components and modules involved are all existing technology and can be fully implemented by those skilled in the art.

[0030] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
