[0001] The utility model relates to the technical field of anti - floating piles, in particular to an anti - floating pile with grouting and enhanced anti - floating ability. Background Art

[0002] When constructing a foundation pit in a water - rich area, the importance of anti - floating piles is self - evident. The construction of a foundation pit in a water - rich area is greatly affected by the groundwater level. If appropriate measures are not taken, the infiltration of groundwater will cause problems such as soil and sediment loss and soil uplift at the bottom of the foundation pit, seriously affecting the construction safety and quality.

[0003] As an important foundation pit support measure, anti - floating piles can play roles such as stabilizing the foundation pit structure, controlling the groundwater level, reducing construction risks, protecting the surrounding environment, and improving construction efficiency during the construction process. Through an effective anti - floating pile system, the challenges faced in the construction of foundation pits in water - rich areas can be effectively addressed, ensuring the safe and stable progress of the project. In many constructions, the foundation reinforcement and the setting of anti - floating piles are carried out separately, and although other grouting anti - floating piles can achieve the effect of grouting, the anti - floating effect is limited. Summary of the Utility Model

[0004] The utility model provides an anti - floating pile with grouting and enhanced anti - floating ability to overcome the technical problem that the existing grouting anti - floating piles have limited anti - floating effect while grouting.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0007] The anti - floating pile body includes an anti - floating pile fixed part above the foundation pit bottom plate and an anti - floating pile soil part below the foundation pit bottom plate. On one side of the anti - floating pile soil part in contact with the soil, there are a number of anti - floating reinforcement bodies. The anti - floating pile soil part is also provided with the slurry outlet hole communicating the outside and the inside of the anti - floating pile body; the anti - floating reinforcement bodies and the slurry outlet holes are arranged at intervals along the axial direction of the anti - floating pile body; the grouting hole is arranged in the anti - floating pile fixed part, and the slurry enters the anti - floating pile body through the grouting hole and flows into the soil through the slurry outlet hole.

[0008] Further, the inlet end of the slurry outlet hole is higher than the outlet end of the slurry outlet hole.

[0009] Further, the anti - floating reinforcement body is a triangular structure with a wider upper part and a narrower lower part, and is arranged along the circumference of the anti - floating pile body.

[0010] Further, it also includes geotextile.

[0011] Further, the geotextile is arranged between the anti - floating reinforcement and the slurry outlet hole.

[0012] Further, the inner side of the geotextile wraps gravel.

[0013] A kind of anti - floating pile with grouting and enhanced anti - floating ability of the utility model realizes the function of in - soil grouting by setting grouting holes and slurry outlet holes on the anti - floating pile. By arranging a number of anti - floating reinforcements on the outer side of the anti - floating pile, the friction between the anti - floating pile and the soil body can be increased, improving the anti - floating effect while achieving the grouting effect, and enhancing the stability and safety of the project.

[0018] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0019] This embodiment provides an anti - floating pile with grouting and enhanced anti - floating ability, as Figure 1 shown, including: an anti - floating pile body 1, an anti - floating reinforcement 2, a grouting hole 3 and a slurry outlet hole 4;

[0020] The anti - floating pile body 1 includes an anti - floating pile fixed part located above the foundation pit bottom plate and an anti - floating pile soil part located below the foundation pit bottom plate. On one side of the anti - floating pile soil part in contact with the soil, there are a number of anti - floating reinforcement bodies 2. The anti - floating pile soil part is also provided with slurry outlet holes 4 that communicate the outside and inside of the anti - floating pile body 1. The anti - floating reinforcement bodies 2 and the slurry outlet holes 4 are arranged at intervals along the axial direction of the anti - floating pile body 1. The grouting holes 3 are arranged in the anti - floating pile fixed part, and the slurry enters the anti - floating pile body 1 through the grouting holes 3 and flows into the soil through the slurry outlet holes 4.

[0021] Specifically, the anti - floating pile body 1 includes an anti - floating pile fixed part located above the foundation pit bottom plate and an anti - floating pile soil part located below the foundation pit bottom plate. The soil part is inserted into the soil, and the fixed part is located outside the soil. Taking the actual foundation pit bottom plate as the boundary, there is a grouting hole in the fixed part outside the soil, and the slurry is injected into the anti - floating pile body through the grouting hole. In the part inside the soil, there are a number of anti - floating reinforcement bodies, and there are also slurry outlet holes 4 that communicate the outside and inside of the anti - floating pile body 1. The slurry outlet holes and the anti - floating reinforcement bodies are arranged at intervals along the axial direction of the anti - floating pile body. The number and spacing of the anti - floating reinforcement bodies and the slurry outlet holes can be selected according to the actual situation. The grouting holes are used to make the slurry injected into the anti - floating pile body flow into the external soil, so as to achieve the effect of strengthening the soil and the foundation.

[0022] In a specific embodiment, as Figure 2 shown, the slurry outlet holes 4 are arranged obliquely upward from the bottom to the top of the anti - floating pile body 1. The inlet end of the slurry outlet hole located inside the anti - floating pile is higher than the outlet end located outside the anti - floating pile.

[0023] In this embodiment, the shape of the slurry outlet hole is rectangular. An opening is made on the anti - floating steel pipe pile body by inclining upward from the bottom direction of the anti - floating pile body. After grouting, the slurry can flow out of the slurry outlet hole and enter the soil layer. Due to the inclination of the slurry outlet hole, it is difficult for the external soil to enter the anti - floating steel pipe pile through the slurry outlet hole, ensuring that the slurry outlet hole is not blocked. After the slurry enters the soil layer, it fills the pores and gaps in the soil, improves the density and strength of the soil, and reduces the permeability of the soil, thereby strengthening the soil and improving the bearing capacity and stability of the soil.

[0024] In a specific embodiment, the anti - floating reinforcement body 2 is a triangular structure with a wider top and a narrower bottom, and is arranged along the circumference of the anti - floating pile body 1.

[0025] The lower half of the anti - floating pile enters the soil, and the reinforcement body is wrapped by the soil, which can effectively increase the contact area between the anti - floating pile and the soil, increase the friction force between the anti - floating pile and the soil, and the reinforcement body is inserted into the soil, which can play a role in strengthening and supporting the anti - floating pile, further enhancing the anti - floating performance.

[0026] In a specific embodiment, it further includes a geotextile 5, and the geotextile 5 is arranged between the anti-floating reinforcement 2 and the grout outlet hole 4, and the inside of the geotextile 5 is wrapped with gravel.

[0027] Wrap a layer of geotextile under the grout outlet hole, wrap gravel inside the geotextile. Before grouting, the geotextile can enhance the friction coefficient of the anti-floating steel pipe pile to improve the anti-floating effect of the anti-floating pile steel pipe pile. After grouting, the grout flows out from the grout outlet hole, and at the same time enters the geotextile through the pores on the geotextile, filling the gaps between the gravel inside the geotextile, which can further improve the anti-floating performance of the anti-floating steel pipe pile and the strength of the surrounding soil.

[0028] The utility model is used in the process of foundation pit construction in water-rich areas, and the using process is as follows:

[0029] According to the actual construction situation, dig out several grout outlet holes obliquely upward from bottom to top in the part of the anti-floating pile body inserted into the soil. According to the actual situation, set several inverted triangular anti-floating reinforcements on the circumference of the part of the anti-floating pile inserted into the soil. Set a geotextile between the anti-floating reinforcement and the grout outlet hole, and wrap gravel in the geotextile to increase the friction force with the soil; after the pit excavation is completed, drill grouting holes on the upper side of the foundation pit bottom plate, and grout the anti-floating steel pipe pile through the grouting holes. The grout discharges from the grout outlet hole, and at the same time also flows out from the bottom of the anti-floating steel pipe pile and enters the soil. The grout flows out from the grout outlet hole, enters the geotextile, and fills the gaps of the gravel wrapped in the geotextile, which can further enhance the friction coefficient of the anti-floating steel pipe pile and thus improve its anti-floating ability;

[0030] This device can effectively reduce the floating and sinking phenomenon of the foundation pit bottom plate, reinforce the foundation soil under the foundation pit bottom plate, increase the stability of the project, and combine the anti-floating pile with grouting, reducing the construction steps and saving time for the project.

[0031] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
