Description

Technical Field

[0001] The utility model relates to the field of sidewalk engineering, and more specifically, to an assembled base layer for sidewalks. Background Art

[0002] The sidewalk is the part of the road that is separated by curb stones, guardrails and other similar facilities for pedestrians only. According to different needs and regional characteristics, sidewalks can be divided into various types. The fitness sidewalk is a kind of sidewalk for people to carry out leisure and fitness activities, and is generally located in scenic areas such as parks, mountains, and river banks.

[0003] The sidewalk base layer is one of the important components of the sidewalk structure, which plays the role of bearing and transmitting loads, and has certain waterproof and drainage properties. The existing sidewalk base layers are often laid by splicing concrete blocks, and then mortar is used for joint filling treatment to improve the integrity and stability of the base layer. However, ordinary concrete has poor water permeability, and the water permeability of the sidewalk base layer is further reduced after joint filling treatment with mortar, resulting in poor drainage performance of this assembled sidewalk base layer. If this assembled sidewalk base layer with poor drainage performance is applied to the fitness sidewalk, it is easy to cause a large amount of accumulated water to remain on the fitness sidewalk after rain, and people are prone to slip and fall when carrying out leisure and fitness activities on the fitness sidewalk. Summary of the Utility Model

A plurality of groups of the block units are laid along the second direction to form an assembled sidewalk base layer, and a plurality of groups of the block units laid along the second direction are mutually attached to each other. The second direction is perpendicular to the first direction. The mutually attached block assemblies form a drainage channel at the first face chamfer, and the drainage channel penetrates through the top surface and the bottom surface of the assembled sidewalk base layer.

[0006] By using the assembled sidewalk base layer of the utility model, a drainage channel is formed between the mutually attached block assemblies, and rainwater can enter the underlying cushion layer and the groundwater system through the drainage channel, greatly improving the drainage performance of the assembled sidewalk base layer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Reference will now be made to example embodiments to discuss the subject matter described herein. It should be understood that these embodiments are discussed so that those skilled in the art can better understand and thus implement the subject matter described herein. Changes can be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0025] For a better understanding of the present utility model, the following will be combined with Figures 1-5 a detailed description of the prefabricated base for the sidewalk of the present utility model will be given.

[0026] Example 1:

[0027] As Figures 1-4 shown, the prefabricated base for the sidewalk includes: a block body 1 and a connecting portion 2 connected to the block body 1. First face chamfers 3 are provided at the edges of two sides of the block body 1 perpendicular to the first direction. The block body 1 and the connecting portion 2 form a block assembly 4. A plurality of the block assemblies 4 are laid along the first direction to form a block unit 5, and the plurality of the block assemblies 4 laid along the first direction are mutually adhered. A plurality of groups of the block units 5 are laid along the second direction to form the prefabricated base for the sidewalk, and the plurality of groups of the block units 5 laid along the second direction are mutually adhered. The second direction is perpendicular to the first direction. The mutually adhered block assemblies 4 form a drainage channel 6 at the first face chamfer 3, and the drainage channel 6 penetrates the top surface and the bottom surface of the prefabricated base for the sidewalk.

[0028] It should be noted that the prefabricated base for the sidewalk is laid on a cushion layer. The cushion layer material is generally selected as pervious materials such as graded crushed stone and gravel to improve the drainage performance and bearing capacity of the prefabricated base for the sidewalk; one or more layers of pervious geotextiles can be laid above the prefabricated base for the sidewalk to effectively intercept soil particles, fine sand, small stones, etc., and prevent the drainage channel 6 from being blocked, affecting the drainage performance of the prefabricated base for the sidewalk.

[0029] By using the prefabricated base for the sidewalk of the present utility model, a drainage channel 6 is formed between the mutually adhered block assemblies 4. After rainwater seeps from the sidewalk surface into the prefabricated base for the sidewalk, it will enter the drainage channel 6, and the drainage channel penetrates the top surface and the bottom surface of the prefabricated base for the sidewalk. The rainwater will enter the underlying cushion layer and the groundwater system through the drainage channel 6, greatly improving the drainage performance of the prefabricated base for the sidewalk and reducing the risk of slipping and falling caused by the accumulation of water on the sidewalk surface after rain, making the road surface slippery.

[0030] Example 2:

[0031] As an optimization of Embodiment 1, as Figure 1 , Figure 2 , Figure 3 , Figure 5 shown, the connecting portion 2 includes a positioning block 7 and a positioning pin 8. Grooves 9 are provided on both sides of the block body 1 perpendicular to the second direction, and the grooves 9 penetrate through both sides of the block body 1 perpendicular to the first direction. At least two positioning blocks 7 are provided, and the positioning blocks 7 are fixedly installed at the openings of the grooves 9 and protrude from the side of the block body 1 perpendicular to the second direction. An adjacent two positioning blocks 7 of the same set of block units 5 and the block body 1 enclose a splicing groove 10. After the pavement prefabricated base is laid, at least a part of the positioning blocks 7 of one set of block units 5 is located in the splicing groove 10 of the adjacent block units 5;

[0032] The block body 1 is provided with insertion holes 11, and the insertion holes 11 communicate with the grooves 9. The insertion holes 11 and the positioning blocks 7 on the same block assembly 4 are arranged in a staggered manner. The positioning blocks 7 are penetrated with through holes 12 that cooperate with the insertion holes 11. The positioning pins 8 are inserted into the insertion holes 11 of one set of block units 5 and the through holes 12 of another adjacent set of block units 5. At least two positioning pins 8 are provided. One block assembly 4 of one set of block units 5 can connect two adjacent block assemblies 4 of the adjacent set of block units 5 into a whole through the positioning pins 8.

[0033] It should be noted that the positions of the positioning blocks 7 installed in the two grooves 9 of the same block body 1 are corresponding; the part of the positioning blocks 7 of one set of block units 5 located in the splicing groove 10 of the adjacent block units 5, that is, the part of the positioning blocks 7 protruding from the side of the block body 1 perpendicular to the second direction, and the design of the splicing groove 10 is to accommodate the protruding positioning blocks 7 to ensure that multiple sets of block units 5 laid along the second direction can be in a mutually fitting state. Therefore, adjacent two sets of block units 5 are arranged in a staggered manner; the positioning pins 8 limit the movement of the block body 1 in the horizontal direction, that is, limit the movement of the block body 1 along the first direction and the second direction.

[0034] In this embodiment, the cross-section of the block body 1 perpendicular to the first direction is an I-shape, and the connecting portion 2 includes two positioning blocks 7 and four positioning pins 8. The two positioning blocks 7 are respectively installed in the middle of the openings of the two grooves 9 of the block body 1. Four insertion holes 11 are opened on the block body 1, and the four insertion holes 11 are respectively located at the four corners of the block body 1. Each positioning block 7 is penetrated by two through holes 12 that cooperate with the insertion holes 11. One block assembly 4 of a group of block units 5 can connect a total of four block assemblies 4 of two adjacent groups of block units 5 into a whole through four positioning pins 8.

[0035] By inserting the positioning pins 8 into the insertion holes 11 of one group of building block units 5 and the through holes 12 of another group of adjacent building block units 5, the movement of the building block body 1 in the horizontal direction can be restricted. After the positioning pins 8 are inserted, the multiple building block bodies 1 are fitted together. Due to the restrictive effect of the positioning pins 8, the multiple building block bodies 1 form a whole and cannot move relative to each other in the horizontal direction, thereby improving the integrity of the prefabricated base of the sidewalk.

[0036] Embodiment 3:

[0037] As a further optimization of Example 2, Figures 1-4 As shown, the groove 9 is located in the middle of the side surface of the building block body 1 perpendicular to the second direction, and the width of the positioning block 7 is consistent with the width of the groove 9.

[0038] It should be noted that the width of the positioning block 7 refers to the size of the positioning block 7 in the third direction, the width of the groove 9 refers to the size of the groove 9 in the third direction, and the first direction, the second direction and the third direction are perpendicular to each other; the positioning block 7 is used to limit the movement of the block body 1 in the vertical direction, that is, to limit the movement of the block body 1 in the third direction.

[0039] The positioning block 7 can limit the movement of the block body 1 in the vertical direction, thereby improving the stability of the sidewalk prefabricated base. When the upper part of the block body 1 is under load, the positioning block 7 can provide certain support to the groove 9 of the block body 1, thereby improving the bearing capacity of the sidewalk prefabricated base, preventing the block body 1 from being severely deformed or even crushed, and improving the service life of the sidewalk prefabricated base.

[0040] Embodiment 4:

[0041] As a further optimization of Example 3, Figure 5 As shown, the length of the positioning block 7 is half of the length of the groove 9 , and the size of the splicing groove 10 is adapted to the size of the positioning block 7 .

[0042] It should be noted that the length of the positioning block 7 refers to the dimension of the positioning block 7 in the first direction, and the length of the groove 9 refers to the dimension of the groove 9 in the first direction.

[0043] Since the length of the splicing groove 10 is the same as that of the positioning block 7, the positioning blocks 7 on the mutually approaching sides of two adjacent groups of building block units 5 are mutually attached along the first direction. When the building block main body 1 bears the load along the first direction, the load along the first direction is mainly borne by the mutually attached positioning blocks 7, and the shear stress along the first direction borne by the positioning pins 8 is relatively small, and it is not easy to be damaged.

[0044] Embodiment 5:

[0045] As an optimization of Embodiment 4, as Figures 1-3 shown, a positioning groove 13 is provided on the inner side wall of the groove 9. The positioning groove 13 communicates with the groove 9, and the positioning groove 13 is used to assist the positioning block 7 in positioning and installation; one end of the positioning block 7 close to the positioning groove 13 is fixedly installed in the positioning groove 13 through structural adhesive.

[0046] It should be noted that a part of the positioning block 7 is installed in the positioning groove 13. After the positioning block 7 is installed, the positioning block 7 is attached to the inner wall of the positioning groove 13.

[0047] By providing the positioning groove 13, it is beneficial to the precise installation of the positioning block 7. If the positioning groove 13 is not provided, when installing the positioning block 7, the position of the positioning block 7 is likely to deviate, affecting the splicing and laying of the building block assembly 4. By using structural adhesive for the fixed connection between the positioning block 7 and the building block main body 1, it is beneficial to the rapid installation of the positioning block 7, and the structural adhesive has a very high bonding strength, which can ensure the connection relationship between the positioning block 7 and the building block main body 1, and the positioning block 7 is not easy to fall off.

[0048] Embodiment 6:

[0049] As a further optimization of Embodiment 5, as Figure 1 and Figure 3 shown, a second chamfer 14 is provided at the edge of the side surface of the positioning block 7 away from the building block main body 1.

[0050] By providing the second chamfer 14, during the splicing and laying process of the building block assembly 4, the inclined surface at the second chamfer 14 can play a guiding role, facilitating the splicing and laying of the building block assembly 4.

[0051] Embodiment 7:

[0052] As a further optimization of Embodiment 6, the material of the building block main body 1 is an elastic material.

[0053] In this embodiment, the material of the block body 1 is selected as ethylene propylene diene monomer (EPDM). The EPDM material is environmentally friendly and durable, which can reduce the impact on the environment. The block body 1 made of EPDM has good elasticity, can bear a large load, is not easily damaged, and EPDM is a recyclable material. Even if the block body 1 made of EPDM is damaged, it can be recycled, which can reduce the cost of material replacement.

[0054] By using the block body 1 made of EPDM, when people walk, run or jump on the fitness path, the elastic prefabricated base of the sidewalk can slow down the impact force generated during people's movement, reduce the risk of sports injuries, improve the comfort of users, and when the block body 1 bears the load, the block body 1 can produce a certain elastic deformation, playing a certain buffering role. The block body 1 is not easily crushed and damaged, improving the service life of the prefabricated base of the sidewalk and reducing the maintenance cost.

[0055] The embodiments of the utility model have been described above in conjunction with the accompanying drawings. However, this embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms without departing from the purpose of this embodiment and the scope protected by the claims, and all of them belong to the protection scope of this embodiment.
