Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection and traffic noise control, and specifically relates to a rural ecological sound barrier along high-speed railways. Background Art

[0002] With the rapid expansion of the high-speed railway network, the problem of noise pollution generated by it has become increasingly prominent and has become a hot topic of public concern. Especially in quiet rural areas, the high-speed railway noise not only seriously interferes with the daily life of residents, but also may have an unignorable negative impact on the smooth progress of agricultural production.

[0003] Although the traditional sound barrier alleviates the noise problem to a certain extent, the traditional sound barrier has a single size and often does not fit in with the natural environment along the line. It lacks the flexibility to adapt to different rural environments and is difficult to fully and effectively solve the noise reduction needs of rural areas along high-speed railways.

[0004] Therefore, there is an urgent need to develop a new type of sound barrier that has high adaptability and flexibility and can fully integrate into the rural ecological environment to meet the noise reduction needs of rural areas along high-speed railways. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a rural ecological sound barrier along high-speed railways, which can meet rural residential houses with different horizontal and vertical distances from the viaduct along high-speed railways and is applicable to the complex rural environments along high-speed railways in different regions.

[0006] The technical solution of the utility model is as follows:

[0007] A rural ecological sound barrier along high-speed railways is of a box structure. The inside of the box structure is used to fill sound-absorbing materials. The box structure includes: a plurality of unit stainless steel columns arranged in a rectangular array, and each unit stainless steel column is a cubic column; a plurality of buried concrete bases correspondingly connected to the bottoms of the unit stainless steel columns; a plurality of splicing plate structures respectively connected between adjacent unit stainless steel columns, and each splicing plate structure includes: a plurality of unit noise reduction plates connected in sequence, and each unit noise reduction plate is connected through a second mortise and tenon structure.

[0008] Further, the unit stainless steel column and the buried concrete base are connected through a first mortise and tenon structure. The first mortise and tenon structure includes: a circular tenon arranged on the top of the buried concrete base; a circular mortise hole arranged at the bottom of the unit stainless steel column and matching the structure of the circular tenon.

[0009] Further, the second mortise and tenon structure includes: a concave mortise opened on one side surface of the unit noise reduction plate; a convex tenon opened on the side surface of the unit noise reduction plate opposite to the side surface provided with the concave mortise, and the convex tenon matches the concave mortise in structure.

[0010] Furthermore, the unit noise reduction board is connected to the unit stainless steel column through a second mortise and tenon structure. On one side of the column surface of the unit stainless steel column facing the inside of the box structure, there is a concave mortise, and on the other side column surface, there is a convex tenon.

[0011] Furthermore, a circular tenon is provided at the top of the unit stainless steel column.

[0012] Furthermore, bolt holes are provided on the circular tenon of the unit stainless steel column. Bolt holes extending into the circular mortise holes are provided at the column surface position of the unit stainless steel column where the circular mortise holes are provided. Bolt holes are provided on the circular tenon of the buried concrete pedestal.

[0013] Furthermore, the unit noise reduction board is configured with a multi-layer structure. The outer shell is made of plastic-steel profiles, and inside the plastic-steel profiles, color steel plates, rock wool, and polymer foam are sequentially provided.

[0014] Furthermore, raised structures are provided on the two side column surfaces of each unit stainless steel column outside the box structure for fixing bamboo strips to form a bamboo woven net outside the box structure. The bamboo woven net is used for plant climbing. The raised structure includes: a vertical part and a horizontal part. One end of the vertical part is connected to the column surface of the unit stainless steel column, and the other end is connected to the horizontal part.

[0015] Furthermore, there are multiple raised structures on the same column surface of the unit stainless steel column, and the multiple raised structures are equidistantly arranged along the height direction of the unit stainless steel column.

[0016] Furthermore, the unit stainless steel column is of a hollow structure.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. For the present utility model, the length of the splicing board structure is selected by splicing different numbers of unit noise reduction boards according to the actual required length. The thickness of the box body of the sound barrier is adjusted by adjusting the length of the splicing board structure on the side. Moreover, with the design of the circular tenon and circular mortise hole on the unit stainless steel column, by vertically splicing the unit stainless steel columns, the height of the box structure can be stacked according to actual needs. The overall unit structure has stronger flexibility and more convenient on-site installation, and no pollutants such as mud will be generated, effectively reducing the construction volume of the project.

[0019] 2. The present utility model has excellent noise reduction effect: By combining crops with the box structure, the impact of high-speed rail noise on rural areas along the line is effectively reduced. At the same time, crops or other climbing green plants can be used for ecological greening, which better integrates into the rural environment.

[0020] 3. The sound barrier of the utility model has a simple appearance design and can be flexibly adjusted and arranged according to the positional relationship between the site and the high-speed railway viaduct and the landscape requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example

[0030] like Figures 1 to 5As shown in the figure, a rural ecological sound barrier along the high-speed railway is a box structure. The interior of the box structure is used to fill sound-absorbing materials, which can also be filled according to actual situations. If the noise is relatively small, soil for planting can be filled, or common rural sound-absorbing materials such as sand, gravel, bamboo, and straw can be used; if the noise reduction intensity needs to be increased, sound-absorbing and noise-reducing materials can be filled. As Figure 1 shown in the figure, the box structure includes: a plurality of unit stainless steel columns 2, a plurality of buried concrete bases 1, and a plurality of splicing plate structures. The plurality of unit stainless steel columns 2 are arranged in a rectangular array and serve as the side columns of the box structure. Each unit stainless steel column 2 is a cubic column with a hollow structure; the plurality of buried concrete bases 1 are correspondingly connected to the bottom ends of the unit stainless steel columns 2, and the buried concrete bases 1 are pre-buried in the soil to stabilize the entire sound barrier; the plurality of splicing plate structures are respectively connected between adjacent unit stainless steel columns 2. Each splicing plate structure includes: a plurality of unit noise reduction plates 3 connected in sequence. Each unit noise reduction plate 3 is connected through a second mortise and tenon structure 5. Through the flexible splicing and assembly between the unit stainless steel columns 2 and the unit noise reduction plates 3, the sound barrier can form structures such as plate type and box type. According to the different actual elevated heights and rural distances, the number of unit noise reduction plates on each side of the box structure can be adjusted, and the length and thickness of the sound barrier can be flexibly adjusted to adapt to different rural environments.

[0031] As Figure 1 and Figure 3 shown in the figure, the unit stainless steel column 2 and the buried concrete base 1 are connected through a first mortise and tenon structure 4. The first mortise and tenon structure 4 includes: a circular tenon 41 and a circular mortise hole 42. The circular tenon 41 is arranged on the top of the buried concrete base 1; the circular mortise hole 42 is arranged at the bottom of the unit stainless steel column 2 and matches the structure of the circular tenon 41. By inserting the circular tenon 41 on the top of the buried concrete base 1 into the circular mortise hole 42 at the bottom of the unit stainless steel column 2, the splicing of the buried concrete base 1 and the unit stainless steel column 2 can be quickly completed.

[0032] As Figure 1 and Figure 4 shown in the figure, the top of the unit stainless steel column 2 is provided with a circular tenon 41. Two unit stainless steel columns 2 are vertically spliced to enable the height of the sound barrier to be flexibly adjusted. Specifically, the circular mortise hole 42 at the bottom of one unit stainless steel column 2 is inserted into the circular tenon 41 at the top of the other unit stainless steel column 2 to complete the splicing of the two unit stainless steel columns 2.

[0033] As Figure 3 and Figure 4As shown, in order to further fix the spliced unit stainless steel column 2 and the buried concrete base 1, bolt holes 7 are provided on the circular tenon 41 of the unit stainless steel column 2. The unit stainless steel column 2 is provided with bolt holes 7 at the position of the column surface where the circular mortise 42 is provided, and the bolt holes 7 extend into the circular mortise 42. Bolt holes 7 are provided on the circular tenon 41 of the buried concrete base 1. Bolts are inserted into the bolt holes to complete the further fixation of the unit stainless steel column 2 and the buried concrete base 1.

[0034] As Figure 2 shown, the second tenon and mortise structure 5 includes: a concave mortise 51 and a convex tenon 52. The concave mortise 51 is provided on one side surface of the unit noise reduction board 3; the convex tenon 52 is provided on the side surface of the unit noise reduction board 3 that is symmetrical to the side surface where the concave mortise 51 is provided. The convex tenon 52 matches the structure of the concave mortise 51. By inserting the convex tenon 52 into the concave mortise 51 from the upper part of the concave mortise 51, the splicing of two unit noise reduction boards 3 is completed.

[0035] As Figure 1 and Figure 3 shown, the unit noise reduction board 3 is connected to the unit stainless steel column 2 through the second tenon and mortise structure 5. One of the column surfaces of the unit stainless steel column 2 facing the inside of the box structure is provided with a concave mortise 51, and the other column surface is provided with a convex tenon 52. In this way, the splicing of the unit stainless steel column 2 and the unit noise reduction board 3 is completed through the same second tenon and mortise structure 5, simplifying the structure of the sound barrier and improving the splicing efficiency.

[0036] As Figure 5 shown, the unit noise reduction board 3 is configured with a multi-layer structure. The outer shell is a plastic-steel profile 31, and a color steel plate 32, rock wool 33, and a polymer foam 34 are sequentially provided inside the plastic-steel profile 31.

[0037] In some embodiments, as Figure 1 and Figure 3 shown, raised structures 6 are provided on the two column surfaces of each unit stainless steel column 2 on the outer side of the box structure for fixing bamboo strips, so as to form a bamboo woven net on the outer side of the box structure. The bamboo woven net is used for plant climbing to form a green covering layer with a certain density, which can not only achieve a better noise reduction effect, but also make the sound barrier better integrate into the rural environment through the ecological greening of the climbing plants. Specifically, the raised structure 6 includes: a vertical part and a horizontal part. One end of the vertical part is connected to the column surface of the unit stainless steel column 2, and the other end is connected to the horizontal part.

[0038] In order to make the woven bamboo woven net more evenly distributed and provide a more favorable climbing environment for climbing plants, a plurality of raised structures 6 are provided on the same column surface of the unit stainless steel column 2, and the plurality of raised structures 6 are equidistantly arranged along the height direction of the unit stainless steel column 2.

[0039] The above are only several specific preferred embodiments of the present utility model disclosed. However, the embodiments of the present utility model are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
