[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0035] like Figure 1 As shown, according to an embodiment of this disclosure, a straight section railway structure for an industrial plant area is proposed, comprising: a sealing clay section 7 for laying on a wet-type roadbed 8; a two-layer cloth and one-layer membrane 6 laid on the sealing clay section 7; a graded steel slag section 5 laid on the two-layer cloth and one-layer membrane 6; a crushed stone ballast section 4 laid on the graded steel slag section 5; a sleeper 3 laid on the crushed stone ballast section 4; a buffer pad 2 laid on the sleeper 3; and a track 1 laid on the buffer pad 2. The graded steel slag section 5 is compacted in layers of equal thickness, with each layer of graded steel slag having a thickness less than or equal to 20 cm, and the total thickness of the graded steel slag section 5 being greater than or equal to 100 cm.

[0036] Currently, the steel industry is a crucial pillar industry of the national economy, playing a vital role in economic construction, social development, fiscal revenue, national defense, and stable employment, and making significant contributions to ensuring the sound and rapid development of the national economy. However, the contradictions accumulated from the long-term extensive development of the steel industry are becoming increasingly prominent, especially environmental issues, which have become a major factor restricting the development of the steel industry. Steel slag is a byproduct of the steelmaking process, with a huge output, most of which is disposed of as industrial waste through landfill or stockpiling, occupying valuable land resources and causing secondary pollution. The straight section railway structure in the industrial plant area provided in this embodiment includes two layers of cloth and one membrane 6, edge sealing clay section 7, graded steel slag section 5, crushed stone ballast section 4, sleepers 3, buffer pads 2, and track 1. The components are as follows: 7 is the edge-sealing clay section paved on the damp subgrade 8; 6 is the two-layer fabric and one-layer membrane section paved on the edge-sealing clay section 7; 5 is the graded steel slag section paved on the two-layer fabric and one-layer membrane section 6; 4 is the crushed stone ballast section paved on the graded steel slag section 5; 3 is the sleeper section paved on the crushed stone ballast section 4; 2 is the buffer pad paved on the sleeper 3; and 1 is the track section paved on the buffer pad 2. The graded steel slag section 5 has cementitious properties, micro-expansion, and good stability. Replacing some crushed stone with graded steel slag section 5 reduces the amount of stone used, lowering the cost of stone mining and use, and reducing environmental pollution caused by stone mining. Furthermore, steel slag, a byproduct of steelmaking, is typically disposed of as industrial waste through landfill or stockpiling, occupying valuable land resources and causing secondary pollution. Replacing some crushed stone with graded steel slag section 5 allows for the reuse of waste, making it more environmentally friendly. On the other hand, the graded steel slag section 5 is compacted in layers of equal thickness, with each layer less than or equal to 20cm, and the total thickness of the graded steel slag section 5 greater than or equal to 100cm. This design makes the railway structure more suitable for damp roadbeds 8, protecting it from the effects of underground capillary water, improving the structural strength, mechanical properties, and water absorption of the railway structure, thereby enhancing its stability in damp roadbed environments.

[0037] Understandably, the maximum particle size of the steel slag in graded steel slag section 5 is less than or equal to 37.5 mm, the CBR (California bearing ratio) of graded steel slag section 5 is greater than or equal to 120, and the compaction degree of graded steel slag section 5 is greater than or equal to 97%. The slope ratio of graded steel slag section 5 is 1:1.5 to prevent collapse, ensure construction safety, and save costs.

[0038] For example, the compaction degree of the roadbed is greater than or equal to 0.95 at the position 0cm to 50cm below the top surface of the damp type roadbed 8; the compaction degree of the roadbed is greater than or equal to 0.90 at the position 50cm to 120cm below the top surface of the damp type roadbed 8; and the compaction degree of the roadbed is greater than or equal to 0.90 at the position 120cm below the top surface of the damp type roadbed 8, which is the water-soaked part.

[0039] In some examples, such as Figure 1 As shown, the two-layer geotextile and one-layer geomembrane 6 includes: two layers of geotextile and one layer of geomembrane, wherein the geomembrane is disposed between the two layers of geotextile; wherein the geotextile is a composite non-woven geotextile; and the geomembrane is a plastic geomembrane.

[0040] Understandably, the "two-layer geotextile and one-layer geomembrane" configuration (6) consists of two layers of geotextile and one layer of geomembrane. One layer of geotextile is laid on the sealing clay layer (7), and the geomembrane is positioned between the two layers of geotextile. This "two-layer geotextile and one-layer geomembrane" configuration improves the seepage prevention performance of straight sections of railway structures in industrial plant areas and is more suitable for damp roadbeds (8). The geotextile can be a composite non-woven geotextile. Specifically, composite non-woven geotextiles can be made of polyester staple fiber needle-punched geotextile, polyester filament spunbond geotextile, or flat yarn woven fabric. The geomembrane can be made of plastic. Specifically, plastic geomembranes can be made of polyvinyl chloride (PVC) or polyethylene (PE).

[0041] In some examples, the mass of the geotextile mentioned above is 80 g / m. 2 Up to 600g / m 2 The thickness of the geomembrane is 1.2 mm to 2.5 mm.

[0042] It is understandable that the mass of the geotextile is 80g / m. 2 Up to 600g / m 2 The thickness of the geomembrane is 1.2mm to 2.5mm to ensure the seepage prevention performance of the two-layer geotextile and one-layer geomembrane structure and to provide good structural strength. The fabric weights of the two geotextile layers are equal, and the ratio of geotextile fabric weight to geomembrane thickness is 400g / 0.5mm.

[0043] In some examples, the geotextile is adhesively bonded to the geomembrane, and the overlap length of the geotextile and the geomembrane is greater than or equal to 5 cm; and / or the overlap width of the geomembrane is greater than or equal to 30 cm.

[0044] Understandably, geomembranes can be bonded to geotextiles to ensure the stability of the connection between the geomembrane and the geotextile. Specifically, to ensure connection strength, the overlap length between the geotextile and the geomembrane should be greater than or equal to 5 cm, and / or the overlap width of the geomembrane should be greater than or equal to 30 cm.

[0045] In some examples, the thickness of the aforementioned sealing clay portion 7 is 60cm to 80cm.

[0046] Understandably, the sealing clay section 7 is laid on top of two layers of fabric and one layer of film 6, with a clay thickness of 60cm to 80cm, to ensure the performance of the clay layer.

[0048] Understandably, the standard size range of crushed stone particles in section 4 of the crushed stone ballast is 20mm to 70mm. Particles smaller than this range account for less than or equal to 5% of the total weight of the crushed stone particles; particles larger than this range account for less than or equal to 5% of the total weight of the crushed stone particles. Particles larger than 100mm should be discarded. The crushed stone particles must be clean and free of clay lumps and other impurities. Section 4 of the crushed stone ballast is compacted in layers of equal thickness, with each layer less than or equal to 200mm. The slope ratio of section 4 is 1:1.5 to prevent collapse, ensure construction safety, and save costs.

[0049] In some examples, the aforementioned graded steel slag section 5 is wider than or equal to 30 cm on each side relative to the aforementioned crushed stone ballast section 4.

[0050] It is understandable that the graded steel slag section 5 is wider than or equal to 30cm on each side relative to the crushed stone ballast section 4, in order to ensure the connection stability between the graded steel slag section 5 and the crushed stone ballast section 4 and improve the safety and reliability of the railway structure.

[0051] In some examples, the aforementioned sleeper 3 is a wooden sleeper 3, which is 2.5m long, 22cm wide, and 16cm thick, and the quantity of the aforementioned sleeper 3 is 1920 pieces / km.

[0052] It is understood that the sleeper 3 can be made of wood, for example, red pine, larch, Masson pine, spruce, and fir. The sleeper 3 is 2.5m long, 22cm wide, and 16cm thick, and the quantity of the above sleepers 3 is 1920 per kilometer.

[0053] In some examples, the aforementioned cushioning pad 2 is a plastic or rubber pad, and the thickness of the aforementioned cushioning pad 2 is 5mm to 10mm.

[0054] It is understandable that the buffer pad 2 can be made of plastic, such as polyurethane or foam plastic; or it can be made of rubber. By setting the buffer pad 2, the impact force of the track 1 on the sleeper 3 and the structure beneath it is reduced, thereby minimizing damage to the railway structure, improving stability, and extending the service life of the railway structure. Specifically, the thickness of the buffer pad 2 is 5mm to 10mm to ensure its cushioning performance.

[0055] In some examples, the mass of the aforementioned track 1 is 50 kg / m; the gauge of the aforementioned track 1 is one of 1435 mm, 900 mm, 762 mm or 600 mm; and the length of each section of the aforementioned track 1 is 12.5 m or 25 m.

[0056] Understandably, track 1 can be either Class I or Class II track 1. The track gauge of track 1 can be selected from 1435mm, 900mm, 762mm, or 600mm depending on the actual usage. Each section of track 1 is 12.5m or 25m long. The material of track 1 can be manganese steel, carbon steel, high-silicon copper, or copper or silicon rails. Track 1 undergoes full-length quenching treatment to improve structural strength. Track 1 and sleepers 3 can be connected by riveting, spot welding, bolting, or clamping.
