Description

Technical Field

[0001] The present invention relates to the field of railway roadbed slope protection, and in particular to a railway roadbed slope protection calculation method and system based on a composite skeleton. Background Art

[0002] In the prior art, skeleton-based slope protection is an important form of slope protection in railway roadbed slope protection, and it plays an important role in the long-term anti-scouring of the slope surface of the roadbed. The current skeleton slope protection structure generally adopts cast-in-place or prefabricated structure. For cast-in-place structures, there are problems with the cast-in-place skeleton on the slope surface, such as concrete tamping and shape maintenance, which affect the quality of the skeleton. In addition, the cast-in-place concrete skeleton has a long maintenance cycle due to the large amount of formwork support engineering. For prefabricated structures, they are factory-made and of good quality, which can greatly reduce the amount of formwork support engineering. However, the existing prefabricated skeletons are prefabricated in full sections, and there are problems such as heavy prefabricated structures, difficult transportation and masonry, weak joints of components, and easy water leakage and hollowing. To this end, the inventors proposed a railway roadbed slope protection device based on a composite skeleton. A combination of multiple prefabricated components is introduced into this slope protection device. However, the prior art lacks quantitative calculation of the combination of multiple prefabricated components and cannot reflect the correlation between the multiple prefabricated components and the slope protection area. Summary of the Invention

[0058] S423: Calculate the first force coefficient, the second force coefficient and the position information of the connecting skeleton to obtain the arch height correction amount.

[0059] In step S423, the first force coefficient, the second force coefficient, and the position information of the connection skeleton are calculated to obtain the arch height correction value, wherein the calculation formula is:

[0060]

[0061] In the above formula (5), Δh represents the arch height correction amount, k1 represents the first force coefficient, k2 represents the second force coefficient, and x represents the position information of the connection skeleton.

[0066] In this railway roadbed slope protection calculation method, in order to clarify the arrangement structure of different prefabricated components, step S5 is introduced:

[0067] S5: Calculate the skeleton spacing information and the arch height correction information of the connecting skeleton to obtain the slope protection area information of the composite skeleton, and the slope protection area information of the composite skeleton is used to determine the number of different prefabricated components to be set.

[0068] In step S5, when the molded frame includes a plurality of fourth prefabricated components 4, step S5 includes S511 to S514, specifically:

[0069] S511: Acquire area information of the first prefabricated component, area information of the second prefabricated component, area information of the third prefabricated component, and area information of the fourth prefabricated component;

[0070] S512: Calculate the frame spacing information and the arch height correction information of the connecting frame to obtain the slope protection area information of the main frame;

[0071] In step S512, the calculation formula is:

[0072]

[0075] In step S513, since the connecting frame is generally only connected to one side of the second prefabricated component, the number of the second prefabricated component is set to 1, and the calculation formula is:

[0076]

[0077] In the above formula (8), n1 represents the number of the first prefabricated component, n2 represents the number of the second prefabricated component, S1 represents the area of the first prefabricated component, S2 represents the area of the second prefabricated component, and S z Indicates the slope protection area information of the main skeleton.

[0079] In step S514, when the forming frame includes a plurality of fourth prefabricated components 4, only one third prefabricated component 3 is provided on each side of the forming frame. Therefore, the number of third prefabricated components 3 is set to 2, and the calculation formula is:

[0080]

[0081] In the above formula (9), n3 represents the number information of the third prefabricated component, n4 represents the number information of the fourth prefabricated component, S3 represents the area information of the third prefabricated component, S4 represents the area information of the fourth prefabricated component, S l It represents the slope protection area information of the connecting skeleton, H represents the arch height correction information of the connecting skeleton, l represents the skeleton spacing information, and z2 represents the height difference between the side endpoint and the vertex of the connecting skeleton when the connecting skeleton is arranged horizontally.

[0082] like Figure 3 As shown, the connecting skeleton includes two third prefabricated components 3 and a plurality of fourth prefabricated components 4 calculated and determined by the above formula (9); in the main skeleton, it includes one second prefabricated component 2 and a plurality of first prefabricated components 1 calculated and determined by the above formula (8).

[0083] In step S5, when the molded frame includes the fifth prefabricated component 5 and the sixth prefabricated component 6, step S5 further includes S521 to S524, specifically:

[0084] S521: Acquire area information of the first prefabricated component, area information of the second prefabricated component, area information of the third prefabricated component, area information of the fifth prefabricated component, and area information of the sixth prefabricated component;

[0085] S522: Calculate the frame spacing information and the arch height correction information of the connecting frame to obtain the slope protection area information of the main frame;

[0086] In step S522, the calculation principle is the same as that of step S512.

[0087] S523: Calculate the slope protection area information of the main frame, the area information of the first prefabricated component, and the area information of the second prefabricated component to obtain the quantity information of the first prefabricated component and the quantity information of the second prefabricated component;

[0089] S524: Calculate the skeleton spacing information, the arch height correction information of the connecting skeleton, the area information of the third prefabricated component, the area information of the fifth prefabricated component, and the area information of the sixth prefabricated component to obtain the quantity information of the third prefabricated component, the quantity information of the fifth prefabricated component, and the quantity information of the sixth prefabricated component.

[0090] In step S524, when the forming frame includes the fifth prefabricated component 5 and the sixth prefabricated component 6, the sixth prefabricated component 6 is arranged at the center of the forming frame, and the plurality of the fifth prefabricated components 5 are arranged symmetrically about the sixth prefabricated component 6. One third prefabricated component is arranged on each side of the forming frame. Therefore, the number of the third prefabricated components is set to 2, and the number of the sixth prefabricated component 6 is set to 1. The calculation formula is:

[0091]

[0092] In the above formula (10), n3 represents the number information of the third prefabricated component, n5 represents the number information of the fifth prefabricated component, n6 represents the number information of the sixth prefabricated component, S3 represents the area information of the third prefabricated component, S5 represents the area information of the fifth prefabricated component, S6 represents the area information of the sixth prefabricated component, S l It represents the slope protection area information of the connecting skeleton, H represents the arch height correction information of the connecting skeleton, l represents the skeleton spacing information, and z2 represents the height difference between the side endpoint and the vertex of the connecting skeleton when the connecting skeleton is arranged horizontally.

[0093] like Figure 4 As shown, the connecting skeleton includes two third prefabricated components 3, one prefabricated component 6 and a plurality of fifth prefabricated components 5 calculated and determined by the above formula (10); in the main skeleton, it includes one second prefabricated component 2 and a plurality of first prefabricated components 1 calculated and determined by the above formula (8).

[0094] Preferably, the first prefabricated component 1, the second prefabricated component 2, the third prefabricated component 3, the fourth prefabricated component 4, the fifth prefabricated component 5, and the sixth prefabricated component 6 are all double-layer structures, wherein the inner layer is a self-compacting solidified layer and the outer layer is a concrete layer. The self-compacting solidified layer can also be replaced by fluidized solidified soil; the concrete layer can specifically be plain concrete or fiber concrete. When the prefabricated component has a double-layer structure, the self-compacting solidified layer or fluidized solidified soil can provide self-compacting filling and long-term stable support for the outer concrete layer. The concrete layer wraps and protects the self-compacting solidified core material, thereby ensuring the use environment and service life of the prefabricated component. In addition, when the outer concrete layer is equivalent to the formwork, it saves the time of setting up and removing the formwork for cast-in-place concrete, achieving the purpose of saving construction time and cost.

[0095] When different prefabricated components are connected, cement asphalt mortar can be laid according to the full-throw method to achieve the purpose of being mainly flexible while also having rigidity and adapting to the different deformations of each prefabricated component. Among them, the ratio of cement asphalt mortar is: 275kg of construction petroleum asphalt, 530kg of talcum powder, and 1.02 cubic meters of quartz sand (calculated according to apparent density). The corresponding mass ratio at this time is 275kg:530kg:1530kg.

[0096] The burial depth of prefabricated components: In areas where the average annual rainfall is less than 600mm, the burial depth should be 0.4-0.5m; in areas where the average annual rainfall is greater than 600mm, the burial depth should be 0.6m.

[0097] When the outer layer is a concrete layer, the thickness of the concrete precast panel should be 6cm-10cm, preferably 8cm, and the concrete strength range should be C25-C35;

[0098] When fiber concrete is used as the concrete layer, the thickness of the fiber concrete precast panel should be 2.5cm-4cm, preferably 3cm, and the strength range should be CF30-CF40.

[0099] In the concrete layer, the concrete benchmark ratio is: 5-25mm continuously graded crushed stone accounts for 42%-45% of the total weight, natural sand or machine-made sand accounts for 31%-35% of the total weight, cement and other cementitious materials account for 12%-16% of the total weight, admixtures account for 0.15%-0.25% of the total weight; water accounts for 5%-7% of the total weight; the volume content of steel fiber is 0.5%-1%, and the content per cubic meter of concrete should not be less than 40kg; the length of the steel fiber is 20mm-60mm, the equivalent diameter is 0.3mm-0.9mm, and the aspect ratio is 30-80.

[0100] In addition, synthetic fibers, inorganic fibers, etc. can also be used, with a volume content of 0.05% to 1%. Fiber varieties include but are not limited to polyacrylonitrile fibers, polypropylene fibers, polyvinyl alcohol fibers, alkali-resistant glass fibers, basalt fibers, etc.

[0101] The inner layer is a self-compacting solidifying layer, which can be a lightweight concrete filling material. It must meet the requirements of the "Technical Specifications for the Application of Cast-in-Situ Foam Lightweight Soil for Railway Roadbed" and the "Technical Specifications for Bubble Mixed Lightweight Soil Filling Engineering". According to the wet density, the specifications should be FLS500-FLS650 or CF0.6-CF1.0 according to the strength grade.

[0102] When the inner layer uses fluidized solidified soil, it may include cement, water, soil, a curing agent, and a water-reducing agent. The weight ratios are: cement 6%-15% of the dry soil weight; a water-to-solid ratio of 55%-65% (for clayey soils), 55%-60% (for silty clays), and 45%-55% (for sandy soils); a curing agent 0.2%-0.3% of the dry soil weight; and a water-reducing agent 0.7-1% of the dry soil weight. The organic matter content of the dry soil material should be less than 5%, and the slump of the premixed fluidized soil should be 180-220mm. The height of a single layer should generally not exceed 2m. In actual projects, on-site sampling and mix testing are recommended to determine the optimal mix ratio based on design specifications.

[0103] The strength index of the above-mentioned precast concrete slabs should be inversely proportional to the strength index of the self-compacting material. If the precast slab uses high strength, low strength self-compacting material can be used accordingly, and vice versa.
