Description

Technical Field

[0001] This utility model relates to the field of foundation reinforcement technology, and in particular to a building foundation reinforcement device. Background Technology

[0002] Foundation refers to the soil or rock mass beneath a building that supports its foundation. Soil layers used as building foundations are classified as rock, gravelly soil, sandy soil, silty soil, clayey soil, and artificial fill. Foundations are divided into natural foundations and artificial foundations. Foundation reinforcement technology refers to a technique that improves the bearing capacity, deformation characteristics, and stability of a foundation by modifying its physical, structural, or chemical properties.

[0003] During the construction of building foundations, foundation reinforcement piles are generally used as vertical load-bearing components to improve the stability of the foundation. Over time, the foundation is exposed to rainwater erosion, causing the soil around the foundation reinforcement piles to be continuously washed away. This results in excessive exposure of the piles, which eventually leads to the piles losing their reinforcing effect, affecting the stability of the foundation and consequently the stability and safety of the building. Utility Model Content

[0004] The purpose of this application is to provide a building foundation reinforcement device to solve the problem mentioned in the background art, where the foundation is exposed to rainwater erosion for a long time, causing the soil layer near the foundation reinforcement pile to be continuously lost, resulting in excessive exposure of the foundation reinforcement pile from the foundation soil layer. Over time, this will cause the foundation reinforcement pile to gradually lose its reinforcement effect on the foundation, affecting the stability of the foundation, and thus affecting the stability and safety of the building.

[0005] To achieve the above objectives, this application provides the following technical solution: a building foundation reinforcement device, comprising a reinforcement pile, a stud fixed to the top of the reinforcement pile, a carrier plate sleeved on the outside of the stud, a plurality of embedded nails fixed to the bottom of the carrier plate, the plurality of embedded nails being distributed in a circular array, a plurality of barbed nails fixed to the outside of the embedded nails, a through hole provided on the carrier plate for the stud to pass through, a protective mesh slidably sleeved on the outside of the stud, a pressure cap sleeved on the top of the stud, the stud being threadedly connected to the pressure cap, and the protective mesh being located between the carrier plate and the pressure cap.

[0006] Furthermore, the reinforcing pile, stud, carrier plate, and pressure cap are all located on the same vertical axis.

[0007] Furthermore, the lower surface of the protective net is fixed with several protrusions, and the protective net and the protrusions are integrally formed.

[0008] Furthermore, a hexagonal groove is provided on the top of the cap.

[0009] Furthermore, the reinforced pile body is externally fixed with helical blades.

[0010] Furthermore, two positioning holes are provided at the top of the reinforced pile.

[0011] Furthermore, two fixing rods are fixed to the lower surface of the carrier plate, a spring is fixed to the bottom end of the fixing rod, and an insert rod is fixed to the bottom end of the spring. The insert rod is slidably sleeved on the outside of the fixing rod, and the insert rod slides in cooperation with the inner wall of the positioning hole.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In this invention, a reinforcing pile embedded in the soil layer is used for longitudinal reinforcement of the foundation. Several embedded nails can assist the carrier plate in pressing down the reinforcing pile after it is embedded in the soil layer, effectively improving the stability of the reinforcing pile in the foundation. After the protective net is sleeved on the stud, the pressure cap is screwed onto the stud, so that the pressure cap and the carrier plate clamp the protective net, realizing the clamping and fixing of the protective net. When the protective net covers the surface of the foundation, it can slow down the rate of erosion of the surface soil by rainwater, making the reinforcing pile less likely to be exposed, effectively improving the stability and durability of the reinforcing pile for the foundation reinforcement.

[0014] In this invention, when the carrier plate is fitted onto the stud, the fixing rod is fitted onto the outside of the insertion rod, which can be inserted into the corresponding positioning hole. This allows the carrier plate to press down on the reinforced pile while preventing the reinforced pile from rotating with the help of several embedded nails, thereby further improving the stability of the reinforced pile after it is embedded in the foundation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: Reference Figure 1-5 The illustrated foundation reinforcement device includes a reinforcement pile 1, a stud 2 fixed to the top of the reinforcement pile 1, a carrier plate 3 sleeved on the outside of the stud 2, a plurality of embedded nails 4 fixed to the bottom of the carrier plate 3, the embedded nails 4 being arranged in a circular array, a plurality of barbed nails 5 fixed to the outside of the embedded nails 4, a through hole 6 provided on the carrier plate 3 for the stud 2 to pass through, a protective net 7 slidably sleeved on the outside of the stud 2, a plurality of protrusions fixed to the lower surface of the protective net 7, and the protective net 7 and the protrusions being integrally formed, the lower surface of the protective net 7 being provided with Multiple protrusions can be inserted into the soil layer to help the protective net 7 fix its position in the foundation soil layer and better slow down the soil loss with rainwater. The top of the stud 2 is fitted with a pressure cap 8. The reinforcing pile 1, stud 2, carrier plate 3 and pressure cap 8 are all on the same vertical axis. The stud 2 and pressure cap 8 are threaded together. The protective net 7 is located between the carrier plate 3 and pressure cap 8. The top of the pressure cap 8 is provided with a hexagonal groove 9. The opening of the hexagonal groove 9 allows the pressure cap 8 to be screwed onto the stud 2 and the installation work can be completed with the corresponding tools.

[0024] The reinforcing pile 1 embedded in the soil layer is used for longitudinal reinforcement of the foundation. After being embedded in the soil layer, the multiple nails 4 can help the carrier plate 3 press down on the reinforcing pile 1, effectively improving the stability of the reinforcing pile 1 in the foundation. The multiple barbs 5 on the nails 4 make it difficult for the nails 4 to be pulled out of the foundation, further improving the stability of the reinforcing pile 1, the carrier plate 3 and the nails 4 in the foundation. After the protective net 7 is sleeved on the stud 2, the pressure cap 8 is screwed onto the stud 2, so that the pressure cap 8 and the carrier plate 3 clamp the protective net 7, realizing the clamping and fixing of the protective net 7. When the protective net 7 covers the surface of the foundation, it can slow down the rate of erosion of the surface soil by rainwater, making it difficult for the reinforcing pile 1 to be exposed.

[0025] Among them, the external fixed sleeve of the reinforced pile 1 is equipped with a spiral blade 10. The spiral blade 10 is used to facilitate the reinforcing pile 1 to be screwed into the foundation soil layer.

[0026] Among them, the top of the reinforced pile 1 is provided with two positioning holes 11, the lower surface of the carrier plate 3 is fixed with two fixing rods 12, the bottom end of the fixing rod 12 is fixed with a spring 13, the bottom end of the spring 13 is fixed with an insert rod 14, the insert rod 14 is slidably sleeved on the outside of the fixing rod 12, and the insert rod 14 is slidably engaged with the inner wall of the positioning hole 11.

[0027] When the carrier plate 3 is fitted onto the stud 2, the fixing rod 12 is fitted onto the insert rod 14 and can be inserted into the corresponding positioning hole 11. This allows the carrier plate 3 to press down on the reinforced pile 1 while preventing the reinforced pile 1 from rotating with the help of multiple embedded nails 4, thereby further improving the stability of the reinforced pile 1 after it is embedded in the foundation.

[0028] Working principle of this utility model:

[0029] According to the construction drawings, the location for foundation reinforcement is selected. Using appropriate construction equipment, the reinforcement pile 1 is rotated and moved downward, so that the reinforcement pile 1 can be better screwed into the foundation soil layer with the help of the spiral blade 10. After the reinforcement pile 1 is completely inserted into the soil layer, the carrier plate 3 is taken out, the stud 2 is inserted into the through hole 6, and the carrier plate 3 is struck with a hammer so that the embedded nail 4 and the barbed nail 5 are embedded into the foundation soil layer. During this process, the two insert rods 14 are inserted into the two positioning holes 11 respectively, which can guide the through hole 6 on the carrier plate 3 to align with the stud 2, and also prevent the reinforcement pile 1 from continuing to rotate after the carrier plate 3 is installed, thereby improving the stability of the reinforcement pile 1 in the foundation.

[0030] After the carrier plate 3 is installed, take out the protective net 7 and put it over the outside of the stud 2, making sure the protective net 7 is tightly attached to the carrier plate 3. The protrusions on the lower surface of the protective net 7 can embed into the surface soil of the foundation, so that the protective net 7 maintains its own position stability. Take out the pressure cap 8 and screw it onto the stud 2, so that the pressure cap 8 and the carrier plate 3 firmly clamp the protective net 7, further ensuring the stability of the protective net 7 and making the protective net 7 tightly attached to the surface soil of the foundation. In this way, when the foundation is washed by rainwater, the rate of surface soil loss is slowed down, which can prolong the exposure time of the reinforcement pile 1, so that the reinforcement pile 1 can better reinforce the foundation.

[0031] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
