Description

Technical Field

[0001] This utility model relates to the technical field of foundation pit construction devices, specifically a support pile anchoring base. Background Technology

[0002] Foundation pit support is a common construction method in civil engineering, widely used in the support of deep foundation pit excavation to prevent soil collapse and ensure construction safety. In traditional foundation pit support engineering, support piles are usually arranged vertically at equal intervals along the edge of the foundation pit. The piles directly bear the soil pressure and resist lateral loads through their own bending stiffness to prevent displacement of the soil around the foundation pit.

[0003] These piles often experience stress concentration when bearing soil and building loads. If the soil pressure is not effectively distributed, stress concentration occurs at the pile-to-ground connection, potentially leading to excessive localized stress, crack formation, or bending failure, thus affecting the stability and safety of the entire support system. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a support pile anchor base that can effectively address the problem of soil pressure not being effectively dispersed and stress concentration at the connection between the pile and the ground.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a support pile anchoring base, comprising a bottom base, a grouting column, a support assembly, a connector and an anchor rod, wherein the bottom base is sleeved on the concrete support pile, the bottom base is fixed to the ground by the grouting column, and two side seats are provided on the outer peripheral side wall of the bottom base, and the two side seats are respectively connected to the support assembly;

[0006] The support assembly includes an abutment rod, a support rod, and a base. The lower part of the abutment rod is fixed inside the side seat and assists in supporting the concrete support pile.

The base is fixed to the ground by anchor rods.

[0007] As a further technical solution, the lower end of the base is provided with a flange, and the flange is provided with multiple bottom holes along the circumference. The grouting column is inserted into the bottom holes and located in the blind hole in the ground. The diameter of the bottom holes and the blind hole in the ground is larger than the diameter of the grouting column. The grouting column is provided with a grouting hole in the center. The upper end of the grouting hole serves as the grouting port. Multiple grout outlets are opened on the side of the grouting column, and the grout outlets are connected to the grouting hole.

[0008] As a further technical solution, the lower end of the base is provided with a second flange, and the upper circumference of the second flange is provided with multiple insertion holes, and the anchor rod is inserted into the insertion holes and penetrates into the ground.

[0009] As a further technical solution, the included angle between the two side seats on the base is α, where 180°>α≥90°.

[0010] As a further technical solution, the upper end of the abutment rod is connected to an extended auxiliary rod for assisting in supporting the concrete retaining pile.

[0011] As a further technical solution, the upper end of the abutment rod is provided with a splicing top groove, the bottom surface of the splicing top groove has two symmetrical inclined surfaces on both sides, and a pair of lateral threaded holes are symmetrically opened at one end of the inclined surfaces on both sides; the lower end of the extended auxiliary rod is provided with a splicing connecting block, the splicing connecting block is located in the splicing top groove and has two symmetrically provided fixing inclined blocks corresponding to the lateral threaded holes, and fixing screws are passed through the fixing inclined blocks and screwed into the lateral threaded holes.

[0014] As a further technical solution, multiple extended auxiliary rods are connected in sequence.

[0015] As a further technical solution, the base is provided with reinforcing ribs.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When concrete retaining piles are subjected to load pressure applied along the edge of the foundation pit, they tend to tilt towards the direction of the pressure. The base, fixed to the ground, supports the concrete retaining piles, and some of the pressure is transmitted and distributed through the support rods to two bases fixed to the ground on one side of the base, increasing the stability of the concrete retaining piles. The connecting rod and the base increase the contact area between the concrete retaining piles and the stress, allowing for a more even distribution of stress under load and preventing localized stress concentration. Adding extension rods above the connecting rods can further increase the contact area, effectively improving the bearing capacity of the pile foundation and reducing the risk of instability or failure due to excessive stress.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figures 1-8 A type of support pile anchor base includes a bottom base 2, a grouting column 3, a support component 4, a connector 5, and an anchor rod 6. The bottom base 2 is sleeved on the concrete support pile 1 and is fixed to the ground by the grouting column 3. Two side seats 22 are provided on the outer peripheral side wall of the bottom base 2, and the two side seats 22 are respectively connected to the support component 4.

[0031] The support assembly 4 includes an abutment rod 41, a support rod 42, and a base 43. The lower part of the abutment rod 41 is fixed in the side seat 22 and assists in supporting the concrete support pile 1. The upper part of the abutment rod 41 is equipped with a connector 5. One end of the support rod 42 is connected to the connector 5 by bolts, and the other end is connected to the base 43 by bolts. The base 43 is fixed to the ground by anchor rods 6.

[0032] like Figure 1 and Figure 4 As shown, the lower end of the base 2 is provided with a flange 21. Multiple bottom holes 211 are provided along the circumference of the flange 21. The grouting column 3 is inserted into the bottom hole 211 and located in the blind hole on the ground. The diameter of the bottom hole 211 and the blind hole on the ground is larger than the diameter of the grouting column 3. A grouting hole is provided in the center of the grouting column 3. The upper end of the grouting hole serves as the grouting port 31. Multiple grout outlets 32 are provided on the side of the grouting column 3. The grout outlets 32 are connected to the grouting hole.

[0033] like Figure 3 As shown, the lower end of the base 43 is provided with a flange 431, and the upper circumference of the flange 431 is provided with multiple insertion holes 4311. The anchor rod 6 is inserted into the insertion holes 4311 and penetrates into the ground.

[0034] Concrete support pile 1 is inserted into the ground along the edge of the foundation pit. The bottom base 2 is fitted onto the concrete support pile 1. A blind hole is opened at the ground position corresponding to the bottom hole 211 on the flange 21. A grouting column 3 is vertically inserted into the bottom hole 211. Concrete is poured into the grouting port 31 of the grouting column 3. The concrete flows out from the grout outlet 32 ​​and fills the gap between the bottom hole 211 and the grouting column 3. After the concrete solidifies, the grouting column 3 fixes the bottom base 2 to the ground.

[0035] When the concrete support pile 1 is subjected to the load pressure applied along the edge of the foundation pit, the concrete support pile 1 tends to tilt towards the direction of the pressure. The base 2, fixed to the ground, supports the concrete support pile 1. At the same time, part of the pressure is transmitted and distributed through the support rod 42 to the two bases 43 fixed to the ground on one side of the base 2, increasing the stability of the concrete support pile 1. The abutment rod 41 and the base 2 increase the contact area between the concrete support pile 1 and the stress, allowing the concrete support pile 1 to distribute the stress more evenly when under load, avoiding local stress concentration. This effectively improves the bearing capacity of the pile foundation and reduces the risk of instability or failure due to excessive stress.

[0036] Furthermore, such as Figures 3-4 As shown, the included angle between the two side seats 22 on the base 2 is α, where 180° > α ≥ 90°. Within this angle range, the positional distribution of the two bases 43 relative to the base 2 can improve the stability of the system.

[0037] like Figures 5-6 As shown, the upper end of the abutment rod 41 is connected to an extended auxiliary rod 7 for assisting in supporting the concrete retaining pile 1.

[0038] Furthermore, the upper end of the abutment rod 41 is provided with a splicing top groove 411. The bottom surface of the splicing top groove 411 has symmetrical inclined surfaces on both sides, and a pair of lateral threaded holes 412 are symmetrically opened at one end of the inclined surfaces on both sides. The lower end of the extended auxiliary rod 7 is provided with a splicing connecting block 71. The splicing connecting block 71 is located in the splicing top groove 411 and has two symmetrically provided fixing inclined blocks 711 corresponding to the lateral threaded holes 412. Fixing screws 712 are passed through the fixing inclined blocks 711 and are screwed into the lateral threaded holes 412.

[0039] As a further technical solution, the angle between the inner inclined surface of the splicing top groove 411 and the horizontal plane is 45 degrees, that is, the angle between the lateral threaded hole 412 and the horizontal plane is 45 degrees.

[0040] As a further technical solution, the upper end of the extended auxiliary rod 7 is provided with a top groove 2 72, which has the same structure as the spliced ​​top groove 1 411.

[0041] As a further technical solution, multiple extended auxiliary rods 7 are connected in sequence. By adding extended rods 7 above the abutment rod 41, the contact area for the concrete support pile 1 to withstand stress can be further increased.

[0042] As a further technical solution, a reinforcing rib plate 23 is provided on the base 2.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
