Description

Technical Field

[0001] This utility model relates to the field of heating pipeline technology, and in particular to a bottom protection device for corrosion-resistant heating pipeline supports. Background Technology

[0002] As a core infrastructure of urban heating systems, the stability and corrosion resistance of the support base of heating pipelines directly affect their safe operation and service life. In existing technologies, the support base of heating pipelines typically uses simple concrete foundations or metal embedded structures, which present several problems. For example, traditional foundations are mostly flat or columnar structures with weak bonding to the soil, making them prone to tilting or displacement under pipeline vibration, ground settlement, or external impacts. Furthermore, gaps easily appear at the connection between the concrete foundation and the metal components, becoming channels for corrosive media to penetrate.

[0003] Therefore, it is necessary to provide a new anti-corrosion heating pipeline support bottom protection device to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bottom protection device for corrosion-resistant heating pipeline supports.

[0005] The corrosion-resistant heating pipeline support bottom protection device provided by this utility model includes a support steel plate, on which a supporting steel column is fixedly welded, and on which a connecting steel disc is fixedly welded.

[0006] A concrete conical column is poured at the bottom of the steel plate, with the large cone of the concrete conical column located at the bottom.

[0007] Multiple U-shaped steel rods are fixedly welded between the supporting steel plate and the connecting steel disc, and the vertical rods of the U-shaped steel rods are fitted with rotatably connected neoprene rubber sleeves.

[0008] Preferably, the outer surfaces of the supporting steel plate, the supporting steel column, and the connecting steel plate are coated with an epoxy coal tar coating, and the epoxy coal tar coating is coated with a polyurea elastomer coating.

[0009] Preferably, the concrete conical column is provided with a connecting part, and the connecting part is fixedly connected to the bottom of the supporting steel plate.

[0010] Preferably, the concrete conical column and the connecting part are coated with an epoxy resin sealing paint layer, and the epoxy resin sealing paint layer is covered with a high-density polyethylene roll layer.

[0011] Preferably, concrete pads are cast on the steel plates on both sides of the connecting part, and a through hole is opened in the middle of the concrete pad, and a serrated part is provided at the bottom of the concrete pad.

[0012] Preferably, the docking steel disc has docking holes.

[0013] Compared with related technologies, the corrosion-resistant heating pipeline support bottom protection device provided by this utility model has the following beneficial effects:

[0014] In this invention, the bottom of the steel plate is supported by a concrete conical column with a large cone head pointing downwards, which lowers the center of gravity. Combined with the compacted foundation of the bottom sand and gravel pad, this significantly improves the overall resistance to tilting and settlement. The bottom of the concrete pad plate on both sides of the connection part is provided with a serrated part, which can enhance the interlocking with the soil and further prevent the steel plate from shifting. The vertical bar of the U-shaped steel rod is fitted with a rotatable neoprene rubber sleeve, which can buffer minor collisions during pipeline installation or use and reduce mechanical damage to metal parts.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a bottom protection device for a corrosion-resistant heating pipeline support, which includes a steel plate 1, a concrete conical column 4, and a U-shaped steel rod 5.

[0022] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 as well as Figure 3 The supporting steel column 2 is fixedly welded on the supporting steel plate 1, and the connecting steel plate 3 is fixedly welded on the supporting steel column 2. The connecting steel plate 3 has a connecting hole 3a, which facilitates the fixing of the heating pipeline support on the connecting steel plate 3. The outer surfaces of the supporting steel plate 1, the supporting steel column 2 and the connecting steel plate 3 are coated with 2-3 layers of epoxy coal tar coating 8, and the epoxy coal tar coating 8 is coated with a polyurea elastomer coating 9.

[0023] A concrete conical column 4 is poured at the bottom of the supporting steel plate 1, with the large cone head of the concrete conical column 4 located at the bottom. A connecting part 41 is provided on the concrete conical column 4, and the connecting part 41 is fixedly connected to the bottom of the supporting steel plate 1. Both the concrete conical column 4 and the connecting part 41 are coated with an epoxy resin sealing paint layer 401, and the epoxy resin sealing paint layer 401 is covered with a high-density polyethylene roll layer 402.

[0024] In addition, concrete pads 7 are cast on the steel plates 1 on both sides of the connecting part 41, and a through hole 7a is opened in the middle of the concrete pad 7, and a serrated part 71 is provided at the bottom of the concrete pad 7.

[0025] It should be noted that: a pre-embedded pit is dug at the location where the heating pipeline is laid, a 300mm thick sand and gravel cushion layer is laid at the bottom of the pit and compacted, and then the concrete conical column 4 is placed on the sand and gravel cushion layer. After keeping the supporting steel plate 1 level with the ground, the pre-embedded pit is filled to make the supporting steel plate 1 a stable structure. Since the center of gravity of the concrete conical column 4 is located at the bottom, the stability of the supporting steel plate 1 is greatly improved.

[0026] It should also be noted that the bottom of the steel plate 1 is a concrete cone column 4 with the large cone head facing down, which lowers the center of gravity. Combined with the compacted foundation of the bottom sand and gravel pad layer, it significantly improves the overall anti-tilting and anti-settlement ability. The bottom of the concrete pad plate 7 on both sides of the connecting part 41 is provided with a serrated part 71, which can enhance the interlocking with the soil and further prevent the steel plate 1 from shifting.

[0027] The supporting steel plate 1 and the connecting steel disc 3 are connected by welding multiple U-shaped steel rods 5 arranged in a ring to form a three-dimensional support structure, which not only improves the bending resistance of the supporting steel column 2, but also disperses the pressure transmitted by the pipeline.

[0028] Among them, the epoxy coal tar coating 8 of the metal support base (supporting steel plate 1, supporting steel column 2 and connecting steel plate 3) protects and blocks the corrosion path, while the polyurea elastomer coating 9 greatly improves the acid and alkali resistance of the metal support base.

[0029] After the concrete cone column 4 is poured, the epoxy resin sealing layer 401 on the surface blocks the penetration of moisture and chloride ions, while the high-density polyethylene roll layer 402 covering the concrete cone column 4 comes into contact with the soil to prevent corrosive ions in the soil from eroding the concrete cone column 4.

[0030] In this embodiment: a steel cage with the same structure as the concrete cone column 4 is welded to the bottom of the steel plate 1, and then concrete is poured into the steel cage to form the concrete cone column 4.

[0031] It is worth noting that polypropylene fibers (at a dosage of 0.9 kg / m²) were added when the concrete was poured into the conical column 4. 3 This enhances the crack resistance of concrete; or a layer of fiberglass cloth reinforcement is added between the epoxy resin sealing layer 401 and the high-density polyethylene roll layer 402, using the flexibility of the fiber cloth to cover micro-cracks and prevent media penetration.

[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 Multiple U-shaped steel rods 5 are fixedly welded between the supporting steel plate 1 and the connecting steel disc 3, and a rotatably connected neoprene rubber sleeve 6 is fitted on the vertical rod of the U-shaped steel rod 5.

[0033] It should be noted that the U-shaped steel pole 5 is fitted with a rotatably connected neoprene rubber sleeve 6, which can buffer minor collisions during pipeline installation or use and reduce mechanical damage to metal parts.

[0034] The above description is only an embodiment of the present utility model of heating pipeline, and does not limit the patent scope of the present utility model. Any equivalent structural or process transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
