[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 5 As shown, the utility model provides a waste tire reinforced buried pipeline structure.

When the soil overlying the buried pipeline is subjected to external impact loads, the three layers of the second reinforced structure layer 30 can exert a "net bag" effect at this time, thereby improving the bearing capacity of the soil overlying the buried pipeline, reducing the impact force of the external impact load, and thus avoiding the problem of serious deformation or even damage of the buried pipeline caused by the external impact load.

[0031] Specifically, in one embodiment, the first reinforced structure layer 20 includes tire fragments and filling materials. The first reinforced structure layer 20 is formed by mixing and pressing the tire fragments and the filling materials.

[0032] Specifically, in one embodiment, the filling material is soil, and the tire fragments are made of waste tires 100, that is, the waste tires 100 are cut to make tire fragments.

[0033] Specifically, in one embodiment, the volume V1 of the tire fragments and the volume V2 of the filling material, wherein V1 / V2 is equal to 0.4. Setting the ratio of V1 / V2 to 0.4 can improve the structural strength of the first reinforced structure layer 20 and make it have a stronger bearing capacity.

[0034] Specifically, in one embodiment, the thickness of the first reinforced structure layer 20 is D1, and the value range of the thickness D1 is: 10 cm≤thickness D1≤15 cm.

[0035] Specifically, in one embodiment, the second reinforced structure layer 30 includes a plurality of waste tire sidewall layers 31 and a connecting member 32. The plurality of waste tire sidewall layers 31 are arranged along a first direction and a second direction respectively; the connecting member 32 is arranged between two adjacent waste tire sidewall layers 31 among the plurality of waste tire sidewall layers 31, and is used to connect the two adjacent waste tire sidewall layers 31.

[0036] Specifically, in one embodiment, a plurality of waste tire sidewall layers 31 are arranged in a matrix.

[0037] Specifically, in one embodiment, the second reinforcement structure layer 30 includes 16 waste tire sidewall layers 31 , which are distributed in a square matrix.

[0038] Specifically, in one embodiment, the connecting member 32 is made of iron wire or steel wire, one end of the connecting member 32 is tied to one of two adjacent waste tire sidewall layers 31 , and the other end of the connecting member 32 is tied to the other waste tire sidewall layer 31 .

[0039] Of course, in an alternative embodiment not shown in the drawings of the present application, the connecting member 32 is a bolt, and threaded holes are provided on two adjacent waste tire sidewall layers 31. One end of the bolt is threadedly connected to the threaded hole of one of the two adjacent waste tire sidewall layers 31, and the other end of the bolt is threadedly connected to the threaded hole of the other waste tire sidewall layer 31.

[0040] Specifically, in one embodiment, the width of the second reinforcement structure layer 30 is greater than twice the diameter of the buried pipeline 10 .

[0041] Specifically, in one embodiment, the waste tire reinforced buried pipeline structure includes three layers of second reinforced structure layers 30 spaced apart along the third direction, and the value range of the first vertical spacing D2 between two adjacent second reinforced structure layers 30 is: 30cm≤first vertical spacing D2≤50cm, and the value range of the second vertical spacing D3 closest to the buried pipeline 10 among the multiple layers of second reinforced structure layers 30 is: 30cm≤second vertical spacing D3≤50cm.

[0042] Combine the following Figures 1 to 5, a more complete embodiment of the present application is described below:

[0043] The present application provides a waste tire reinforced buried pipeline structure, comprising a buried pipeline, a second reinforced structure layer horizontally laid inside the soil body above the buried pipeline, and a first reinforced structure layer filled in the side of the buried pipeline; the second reinforced structure layer is a mesh structure formed by a plurality of tire edges connected to each other; the first reinforced structure layer is a composite filler formed by tire fragments and a filling material; the filling material is soil; and the buried pipeline is a PVC corrugated pipe.

[0044] The tire sidewalls are made by cutting multiple waste tires, which are connected to each other by wires to form a mesh-like plane structure.

[0045] The tire fragments are formed by cutting a plurality of tire treads (3), each tire fragment has a size of approximately (length×width) 5×7 cm, and in the process of being uniformly mixed with soil to form a composite filler, the volume ratio of the tire fragments to the soil is approximately 2:5.

[0046] The interlayer spacing between the second reinforced structure layers and the distance between the second reinforced structure layer and the buried pipeline c should be between 30 and 50 cm.

[0047] The laying width of the second reinforced structure layer should be greater than twice the diameter of the buried pipeline, and the filling thickness of the first reinforced structure layer should be between 10 and 15 cm.

[0048] In this application, the waste tire reinforcement technology is used to protect the buried pipeline, which not only enhances the engineering application performance of the buried pipeline, but also improves the utilization rate of the tire, and reduces the environmental pollution caused by the waste tire. Compared with the traditional geosynthetics reinforcement technology such as geogrids and geotextiles, the cost is significantly reduced. The working principle is to utilize the high-strength tensile performance of waste tires and the interaction between the tire bead of the waste tire and the soil body to form a stronger lateral constraint effect on the soil body overlying the buried pipeline, and at the same time enhance the structural integrity of the overlying soil body. When the soil body overlying the buried pipeline is subjected to external load, the tire bead reinforcement layer (the second reinforcement structure layer) of the mesh waste tire connected by the connector can play a "net bag" effect at this time, thereby improving the bearing capacity of the soil body overlying the buried pipeline and reducing the deformation. In addition, relative to plain soil, the waste tire fragment reinforced soil has higher strength, rigidity and integrity, so it can form a certain protective effect on the buried pipeline, reducing the impact of external load on the buried pipeline.

[0049] Compared with the conventional buried pipeline structure, the utility model has the following advantages:

[0050] First, the buried pipeline reinforced with waste tires overcomes the defect that the overlying soil may deform too much and cause the buried pipeline to be damaged.

[0051] Second, during the urban road construction process, the reinforced soil layer (the first reinforced structure layer) of waste tire fragments around the buried pipeline can prevent large mechanical engineering vehicles such as forklifts and excavators from having a violent impact on the buried pipeline.

[0052] Third, the meshed waste tire sidewall reinforcement layer (the second reinforcement structure layer) is buried in the soil overlying the buried pipeline. When subjected to ground load, the high-strength tensile strength of the waste tire sidewall stimulates the lateral restraint force of the reinforcement layer on the filler, thereby improving the bearing capacity of the buried pipeline.

[0053] Fourth, the structure of the reinforced buried waste tire pipeline is simple and easy to construct. It can make full use of tire waste and on-site soil and reduce environmental pollution and land occupation.

[0054] Fifth, this application improves the seismic performance of buried pipelines in urban roads to a certain extent, and is economical and environmentally friendly.

[0055] The specific steps for laying waste tire reinforced buried pipelines are as follows:

[0056] The buried pipeline trench is excavated according to the project requirements, and then according to the pre-buried position of the buried pipeline in the trench, a layer of composite filling material made of waste tire fragments is laid near the middle of the bottom of the trench and compacted to a thickness of about 20 cm as the bottom cushion layer of the buried pipeline.

[0057] Use a crane to place the buried pipe on top of the composite filling material of waste tire fragments at the bottom of the trench, and then backfill the soil on both sides of the bottom of the trench, and the compaction thickness is level with the composite filling material of waste tire fragments at the bottom.

[0058] In the areas on both sides of the buried pipeline, the composite filling material of waste tire fragments is backfilled close to the buried pipeline and compacted to a thickness of about 20 cm. After compaction, the horizontal width of the composite filling material of waste tire fragments is maintained at about 10 to 15 cm.

[0059] The soil is backfilled in the area beside the compacted composite filling material of waste tire fragments, and compacted until it is level with the composite filling material of waste tire fragments.

[0060] The above process is repeated in sequence until the composite filling material of waste tire fragments on the top of the buried pipeline is compacted.

[0061] The above construction process enables the composite filling material of waste tire fragments to successfully surround the buried pipeline as the first reinforced structure layer, followed by backfilling of soil and compaction of the soil in layers. The thickness of each layer of soil after compaction is about 20 cm, and a mesh waste tire sidewall reinforcement layer (the second reinforced structure layer) is laid according to the spacing design requirements of each layer of reinforcement material, and the width is not less than 2 times the diameter of the buried pipeline.

[0062] Repeat the above process until the design requirements of the waste tire reinforced buried pipeline are met. The final reinforced buried pipeline structure
