Description

Technical Field

[0001] This invention relates to the field of utility pole technology, and more specifically to a method for manufacturing concrete utility poles and the utility poles themselves. Background Technology

[0002] Patent document CN108623254A, entitled "A Graphene Concrete Utility Pole and Its Preparation Method," discloses a graphene concrete utility pole and its preparation method. The concrete is made from the following raw materials: cement, kaolin, crushed stone, steel slag, coal gangue, fly ash, coarse sand, medium sand, graphene, silane coupling agent, chopped carbon fiber, epoxy acrylate resin, water, and water-reducing agent. While this method yields utility poles with a certain strength, the pursuit of higher strength is a common goal among utility pole manufacturers. However, it also has the drawback of relatively low strength, which may not meet some installation requirements. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a method for manufacturing a concrete utility pole with better strength, and a utility pole in general.

[0004] The technical solution of the present invention for manufacturing a concrete utility pole is as follows: A method for manufacturing a concrete utility pole includes a reinforcing cage and an outer concrete layer, and the production method of the utility pole is as follows: (1) Weigh out the various raw materials according to the required weight proportions, mix and stir to prepare concrete; (2) Place the steel cage in the pole mold and pour concrete into the mold; (3) Vibrate, centrifuge, let stand, demold, and cure the pole mold to obtain a concrete pole; Its characteristic is that the concrete is made by mixing the following materials in the following proportions by mass: 280-320 parts cement, 450-550 parts sand, 280-320 parts 05# gravel, 280-320 parts 10# gravel, 18-22 parts 100-mesh aluminum powder, 55-65 parts 100-mesh ferric oxide powder, 90-100 parts 05# ceramic tile shell, and 120-130 parts water, and then solidifying.

[0005] Furthermore, the raw materials also contain 20 parts of 50-100 mesh iron powder.

[0006] Furthermore, the raw materials also contain 30 parts by weight of modified white glue, which is prepared by mixing white glue, acetic acid and bone glue in a mass ratio of 8:1:2, with the white glue and acetic acid heated to 55-65°C and the bone glue added and stirred.

[0007] Furthermore, the curing process is carried out in an environment of 25-35°C, and successively goes through a heat preservation stage, a heating stage, and a cooling stage. The heat preservation stage is from the time the concrete is poured, and the temperature is maintained at 25-35°C for 24-36 hours; the heating stage is maintained at 35-45°C for 48-60 hours; and the cooling stage is maintained at 20-25°C for 60-72 hours.

[0008] The concrete utility pole of the present invention is obtained by the above-described method for manufacturing a concrete utility pole.

[0009] The beneficial effect of this invention is that such a utility pole has the advantage of better strength. Detailed Implementation

[0010] The present invention will be further described below with reference to embodiments; The method for producing the utility pole is as follows: (1) Weigh out the various raw materials according to the required weight proportions, mix and stir to prepare concrete; (2) Place the steel cage in the pole mold and pour concrete into the mold; (3) Vibrate, centrifuge, let stand, demold, and cure the pole mold to obtain a concrete pole.

[0011] Examples 1-5 The table below is a comparison table of various raw materials and the resulting utility poles in Examples 1-5: Unit (kg) The table below is a comparison table of various utility poles and performance tests. The strength coefficient refers to the ratio of the forces required to break multiple utility poles of the same specification, with their lower ends fixed, when pushed forcefully from the side of their upper ends.

[0012] Conclusion: Adding 100-mesh aluminum powder and 100-mesh ferric oxide powder to concrete can significantly improve the load-bearing strength of utility poles. This is because during the shielding process, the aluminum powder and ferric oxide powder react to produce aluminum oxide and iron, resulting in a stronger bond between the materials and thus enhancing the load-bearing strength of the utility pole.

[0013] Example 6 Repeat steps 1-5 above, except that the raw materials also contain 20 parts of 50-100 mesh iron powder.

[0014] The obtained utility pole is the sixth utility pole.

[0015] The strength coefficient of the sixth utility pole was measured to be 1.3. Conclusion: Adding 50-100 mesh iron powder to concrete can significantly improve the load-bearing strength of utility poles.

[0016] Example 7 Repeat the above embodiments 1-7, except that the raw materials also contain 30 parts by weight of modified white glue. The modified white glue is prepared by mixing white glue, acetic acid and bone glue in a mass ratio of 8:1:2, while the white glue and acetic acid are heated to 55-65°C and bone glue is added and stirred.

[0017] The obtained utility pole is the seventh utility pole.

[0018] The strength coefficient of the seventh utility pole was measured to be 1.3–1.35. Conclusion: Adding modified white latex to concrete can significantly improve the load-bearing strength of utility poles.

[0019] Example 8 Repeat steps 1-8 above, with the difference that the entire curing process is carried out in an environment of 25-35°C, and sequentially goes through a heat preservation stage, a heating stage, and a cooling stage. The heat preservation stage is the stage after the concrete is poured, which is maintained at 25-35°C for 24-36 hours; the heating stage is the stage of maintaining 35-45°C for 48-60 hours; and the cooling stage is the stage of maintaining 20-25°C for 60-72 hours.

[0020] The obtained utility pole is the eighth utility pole.

[0021] The strength coefficient of the eighth utility pole was measured to be 1.35–1.40. Conclusion: Following the above manufacturing process can significantly improve the load-bearing capacity of utility poles.

[0022] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
