Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a steel slag permeable road pavement structure. Background Art

[0002] Steel slag is a composite solid solution formed by adding lime, fluorite and other slag-forming solvents during the steelmaking process. It is an alkaline aggregate with porous physical characteristics. The steel slag used to mix steel slag concrete should be drum-treated before use and undergo secondary processing (crushing, magnetic separation, drying, screening) to produce steel slag aggregate with qualified stability.

[0003] A Chinese utility model patent, authorized with publication number CN214694969U, discloses a steel slag permeable road pavement structure. This pavement structure boasts advantages such as permeability, durability, color adjustability, ease of construction, and short maintenance time. It effectively utilizes tailings and steel slag, conserving natural aggregate resources.

[0004] The above solution solves the technical problems raised in its background technology, but in practical application, certain problems still exist. For example, although the above road has good permeability, it has poor drainage. In the event of concentrated rainfall or when the road is saturated with rainwater, rainwater will overflow onto the road surface, thus affecting its use. Utility Model Content

[0005] The purpose of the utility model is to provide a steel slag permeable road pavement structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel slag permeable road paving structure, comprising a foundation, a plurality of linearly distributed seepage pipes are arranged on the top of the foundation, a plurality of water inlet holes are opened on the pipe body of the seepage pipe, a stabilizing layer is laid on the top of the seepage pipe, a plurality of anti-skid holes are opened on the top of the stabilizing layer, a steel slag permeable layer is laid on the top of the stabilizing layer, and a surface layer is laid on the top of the steel slag permeable layer.

[0007] Preferably, a first filter cloth is provided on top of the seepage outlet pipe and the stabilization layer.

[0008] Preferably, a waterproof engineering cloth is provided between the foundation and the seepage outlet pipe.

[0009] Preferably, a steel mesh is provided between the stabilizing layer and the steel slag permeable layer. The steel mesh is placed on the top of the stabilizing layer through supporting legs. The distance between the steel mesh and the stabilizing layer is 1-8 cm.

[0010] Preferably, a second filter cloth is provided between the steel slag water-permeable layer and the surface layer.

[0011] Preferably, the stabilization layer is a gravel layer.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The steel slag permeable road pavement structure is provided with a first filter cloth and a seepage outlet pipe. When rainwater penetrates downward through the surface layer, the steel slag permeable layer and the temperature layer, the rainwater enters the seepage outlet pipe through the water inlet hole of the seepage outlet pipe, and is then discharged through the outlets on both sides of the seepage outlet pipe, thereby reducing the rainwater retention in the pavement structure and preventing rainwater from overflowing the road surface.

[0014] At the same time, an anti-skid hole is set on the top of the stabilization layer, and the steel slag extension column formed at the bottom of the steel slag permeable layer extends into the anti-skid hole. The mutual cooperation between the steel slag extension column and the anti-skid hole effectively prevents the horizontal displacement of the steel slag permeable layer, thereby improving the stability between the stabilization layer and the steel slag permeable layer.

[0015] In addition, a wire mesh is also provided. When the steel slag water-permeable layer is laid and solidified, the wire mesh is fixed in the middle of the steel slag water-permeable layer, thereby improving the overall strength of the steel slag water-permeable layer, preventing cracks in the steel slag water-permeable layer after long-term use, and improving the service life of the road pavement structure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 - Figure 2As shown, the utility model provides a technical solution: a steel slag permeable road paving structure, comprising a foundation 1 compacted multiple times by a paver, a plurality of linearly distributed seepage pipes 5 are provided on the top of the foundation 1, and in order to prevent the seepage pipes 5 from rusting and reduce construction costs, the seepage pipes 5 are made of PVC material, a plurality of water inlet holes are opened on the pipe body of the seepage pipe 5, the water outlets on both sides of the seepage pipe 5 are connected to a water reservoir or a municipal drainage pipe, and a stabilizing layer 2 is laid on the top of the seepage pipe 5. In order to prevent large impurities from clogging the water inlet hole of the seepage outlet pipe 5, a first filter cloth 6 is provided on the top of the seepage outlet pipe 5 and the stabilization layer 2. The first filter cloth 6 can be selected as a geotextile with good water permeability. Among them, the stabilization layer 2 is a gravel layer with good water permeability. After it is laid on the top of the seepage outlet pipe 5, it is compacted by a vibrating roller. In addition, a waterproof engineering cloth 7 is provided between the foundation 1 and the seepage outlet pipe 5. The provision of the waterproof engineering cloth 7 can reduce the entry of moisture into the foundation 1 and improve the stability of the foundation 1.

[0021] In order to improve the stability between the stabilization layer 2 and the steel slag permeable layer 3 and prevent dislocation after long-term use, a number of anti-skid holes 201 are opened on the top of the stabilization layer 2. It should be noted that the anti-skid holes 201 are opened after the stabilization layer 2 is initially compacted. They are formed by drilling with a micro pile driver. After the anti-skid holes 201 are formed, the stabilization layer 2 is finally compacted by a vibrating roller. A steel slag permeable layer 3 is laid on the top of the stabilization layer 2. The steel slag permeable layer 3 is made of a mixture of steel slag and modified epoxy resin adhesive. After it is laid on the top of the stabilization layer 2 and solidified, a number of steel slag extension columns 301 are formed at its bottom. The steel slag extension columns 301 extend in the anti-skid holes 201. A surface layer 4 made of rubber, plastic or asphalt material is laid on the top of the steel slag permeable layer 3. In order to prevent some unbonded steel slag from being washed onto the road surface by water, a second filter cloth 8 made of geotextile is provided between the steel slag permeable layer 3 and the surface layer 4.

[0022] In another embodiment of the present scheme, a steel mesh 9 is provided between the stabilizing layer 2 and the steel slag water-permeable layer 3, wherein the steel mesh 9 is placed on the top of the stabilizing layer 2 through supporting legs, and the distance between the steel mesh 9 and the stabilizing layer 2 is 1-8 cm. In this way, when the steel slag water-permeable layer 3 is laid and solidified, the steel mesh 9 is fixed in the middle of the steel slag water-permeable layer 3, thereby improving the overall strength of the steel slag water-permeable layer 3, preventing the steel slag water-permeable layer 3 from cracking after long-term use, and improving the service life of the road pavement structure.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
