Description

Technical Field

[0001] This utility model belongs to the technical field of civil engineering, specifically relating to a corrosion-resistant composite pile foundation structure. Background Technology

[0002] Land-based buildings and marine engineering structures all have pile foundations driven into the soil and rock layers to a certain depth as supporting foundations. The part of the pile body that penetrates into the soil and rock layers (i.e., the part that penetrates into the deep soil and rock layers) is mainly subjected to axial force, while the horizontal force and bending moment are relatively small. Usually, the increase in the length of the pile body is mainly to meet the axial bearing capacity requirements of the pile foundation structure. The conventional pile foundation construction process includes drilling, hole cleaning, lowering the steel cage, pouring concrete, and pile quality inspection. Existing corrosion-resistant composite pile foundation structures are mainly composed of components such as support columns, protective layers, anti-corrosion sleeves, anti-corrosion coatings, casting slabs, inlet ports, outlet ports, and filling holes. However, the support columns of existing corrosion-resistant composite pile foundation structures are not very stable and are prone to tilting during use. Therefore, a corrosion-resistant composite pile foundation structure is essential. Utility Model Content

[0025] 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.

[0026] This utility model provides, for example Figure 1-3 The corrosion-resistant composite pile foundation structure shown includes a protective sleeve 8 and a stabilizing plate 3 located inside the protective sleeve 8. An insertion hole 13 is provided inside the stabilizing plate 3, and a support column 7 is installed inside the insertion hole 13. A first limiting knob 9 and a second limiting knob 10 are respectively installed on the upper and lower sides of the support column 7. A filling hole 2 is provided inside the stabilizing plate 3. A casting plate 6 is installed at the upper end of the protective sleeve 8 and the support column 7. An inlet 4 is provided inside the upper end of the casting plate 6, and an outlet 5 is provided inside the lower end of the casting plate 6, corresponding to the filling hole 2. An anti-corrosion sleeve 12 is installed outside the support column 7, inside the insertion hole 13, and the inner wall of the anti-corrosion sleeve 12 is coated with an anti-corrosion coating 11. A thick soil layer 1 is provided at the lower outer position of the protective sleeve 8 and the support column 7; the stability of the corrosion-resistant composite pile foundation structure is enhanced by the setting of the stabilizing plate 3, the first limiting knob 9 and the second limiting knob 10.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, to enhance the stability of the corrosion-resistant composite pile foundation structure, when using the corrosion-resistant composite pile foundation structure, firstly, the anti-corrosion sleeve 12 is installed on the outside of the support column 7. Then, the second limiting knob 10 is connected to the anti-corrosion sleeve 12 via threads. Next, the support column 7 is inserted into the insertion hole 13, so that the stabilizing plate 3 is located above the second limiting knob 10. Then, the first limiting knob 9 is connected to the anti-corrosion sleeve 12 via threads, so that the first limiting knob 9 and the second limiting knob 10 are located on the upper and lower sides of the stabilizing plate 3, thereby restricting the stabilizing plate 3 and the support column 7. Then, the protective sleeve 8 is installed on the outside of the stabilizing plate 3. The corrosion-resistant composite pile foundation structure is inserted into the installation hole inside the thick soil layer 1. Then, the casting plate 6 is installed on the upper end of the support column 7. At this time, concrete can be poured into the casting plate 6 through the inlet 4 and then into the filling hole 2 through the outlet 5. When the concrete is almost out of the inlet 4, the pouring is stopped. After the concrete dries, the casting plate 6 is removed, and the poured platform is then ground smooth. The stability of the corrosion-resistant composite pile foundation structure is enhanced by the setting of the stabilizing plate 3, the first limiting knob 9 and the second limiting knob 10, thereby reducing the amount of steel material and lowering the cost while meeting the bearing capacity requirements of the pile foundation structure.

[0028] The stabilizing plate 3, the insertion hole 13, and the support column 7 are all provided with multiple insertion holes 13. The insertion hole 13 passes through the stabilizing plate 3. The outer diameter of the support column 7 is smaller than the inner diameter of the insertion hole 13. The support column 7 and the insertion hole 13 are connected by a plug-in connection. The outer wall of the anti-corrosion sleeve 12 is provided with an external thread. The inner wall of the first limiting knob 9 and the second limiting knob 10 is provided with an internal thread. The first limiting knob 9 and the second limiting knob 10 are connected to the external thread of the outer wall of the anti-corrosion sleeve 12 through the internal thread of the inner wall, thereby restricting the stabilizing plate 3 and the support column 7.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, when using a corrosion-resistant composite pile foundation structure, the anti-corrosion sleeve 12 is first installed on the outside of the support column 7. Then, the second limiting knob 10 is connected to the anti-corrosion sleeve 12 via threads. Next, the support column 7 is inserted into the insertion hole 13, so that the stabilizing plate 3 is located at the upper end of the second limiting knob 10. Then, the first limiting knob 9 is connected to the anti-corrosion sleeve 12 via threads, so that the first limiting knob 9 and the second limiting knob 10 are located on the upper and lower sides of the stabilizing plate 3, thereby restricting the stabilizing plate 3 and the support column 7. The setting of internal and external threads facilitates the restriction of the stabilizing plate 3 by the first limiting knob 9 and the second limiting knob 10, thereby making the placement of the stabilizing plate 3 more stable.

[0030] The anti-corrosion sleeve 12 is made of rubber material, and the anti-corrosion coating 11 is made of polyurethane coal tar paint. The anti-corrosion sleeve 12 will compress the insertion hole 13. Through the setting of the anti-corrosion sleeve 12 and the anti-corrosion coating 11, the anti-corrosion performance of the corrosion-resistant composite pile foundation structure is enhanced.

[0031] like Figure 2 and Figure 3 As shown, in order to enhance the corrosion resistance of the corrosion-resistant composite pile foundation structure, when using the corrosion-resistant composite pile foundation structure, the anti-corrosion coating 111 is first evenly applied to the inner wall of the anti-corrosion sleeve 12, and then the anti-corrosion sleeve 12 is installed on the outside of the support column 7. When the anti-corrosion sleeve 12 comes into contact with the support column 7, the inner wall of the anti-corrosion sleeve 12 will squeeze the support column 7. When the support column 7 is buried in a thick soil layer, the anti-corrosion sleeve 12 and the anti-corrosion coating 11 at the position of the inner wall of the anti-corrosion sleeve 12 will prevent the support column 7 from being corroded. Through the setting of the anti-corrosion sleeve 12 and the anti-corrosion coating 11, the corrosion resistance of the corrosion-resistant composite pile foundation structure is enhanced, so that the support column 7 can be used better.

[0032] 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.
