Description

Technical Field

[0001] This utility model relates to the field of permeable concrete technology, specifically to a crack-resistant permeable concrete structure. Background Technology

[0002] Road construction generally includes two structural types: cement concrete pavement and asphalt pavement. Asphalt pavement has gradually replaced cement concrete pavement. Construction requires compacting the roadbed before laying a supporting subbase, lower base course, and base course, finally topped with an upper course. Due to various environmental factors such as pavement structure, climate, topography, geological conditions, and traffic load, the base course, whether flexible or semi-rigid, will develop cracks of varying degrees and shapes. In particular, heavy vehicle loads generate resonance during travel, which is transmitted to the pavement, causing downward cracking. Combined with the heavy traffic load, this eventually damages the pavement, requiring repair, which is quite troublesome.

[0003] Therefore, the research objective of this utility model is to design a crack-resistant permeable concrete structure that is not only easy to construct, but also enhances road surface strength and reduces vibrations during driving, thereby effectively reducing the occurrence of road surface cracks. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the present invention provides a crack-resistant permeable concrete structure, which can effectively solve the technical problems existing in the prior art.

[0005] The technical solution of this utility model is:

[0006] A crack-resistant permeable concrete structure includes: a compacted soil layer, a crushed stone cushion layer, a permeable concrete base layer, a permeable concrete surface layer, and a surface layer protective layer laid sequentially from the ground upwards; and a connecting component for connecting the crushed stone cushion layer, the permeable concrete base layer, and the permeable concrete surface layer. The connecting component includes a plurality of vibration-damping three-dimensional members embedded at intervals in the upper inner side of the crushed stone cushion layer. The top of each vibration-damping three-dimensional member is fixedly connected to a steel bar that penetrates the permeable concrete base layer and extends to the top of the permeable concrete base layer. A corresponding steel mesh is laid at the junction of the permeable concrete base layer and the permeable concrete surface layer, and the top of the steel bar is fixedly connected to the steel mesh.

[0007] The vibration damping three-dimensional component is a sphere or ellipsoid with a smooth arc-shaped outer surface and a hollow interior filled with damping particles for vibration damping. The damping particles for vibration damping are spherical particles made of corrosion-resistant alloy material.

[0008] The vibration damping three-dimensional component is a sphere or ellipsoid with a smooth arc-shaped outer surface and a hollow interior with multiple vibration damping plates fixed at intervals from top to bottom. The vibration damping plates are evenly distributed with many corresponding vibration damping micro-holes, and the vibration damping plates are coaxially provided with through holes for passing through the reinforcing bars.

[0009] The upper surface of the vibration damping component is planar, and a corresponding limiting cylinder is fixedly installed inward from the middle of the upper surface. The limiting cylinder is detachably plugged with a corresponding plug body. The top of the plug body is higher than the top of the limiting cylinder, or a pulling rope for removing the plug body is fixedly connected. When the vibration damping component is embedded and fixed in the crushed stone cushion layer, its upper surface is flush with the upper surface of the crushed stone cushion layer.

[0010] After the vibration damping three-dimensional component is embedded and fixed in the crushed stone cushion layer, the plug is taken out and the reinforcing bar is inserted and fixedly connected in the limiting cylinder and the permeable concrete base layer is filled until the top of the reinforcing bar protrudes from the upper surface of the permeable concrete base layer. Then, the reinforcing mesh is laid on the upper surface of the permeable concrete base layer and fixedly connected to the reinforcing bar.

[0011] The top and bottom of the steel bar are fixedly connected to the steel mesh and the vibration damping component by spot welding, respectively, and the bottom of the steel bar passes through the limiting cylinder and extends to abut against the bottom of the vibration damping component.

[0012] The vibration damping three-dimensional components are arranged in an alternating manner, and the steel bars are fixedly connected to the intersection points of the horizontal and vertical steel mesh.

[0013] Advantages of this utility model:

[0014] 1) This utility model adds corresponding connecting components to the high-grade pavement. The connecting components connect the load-bearing crushed stone cushion layer, permeable concrete base layer and permeable concrete surface layer of the pavement to form a whole, which enhances the strength of the pavement. When vehicles pass over the pavement, the force can be distributed. When the vehicle resonates and is transmitted downward to the pavement, the vibration energy is effectively reduced by the frictional energy dissipation between damping particles or by the vibration energy dissipation formed in the pores of the vibration damping plate, thereby achieving the effect of crack resistance.

[0015] 2) Furthermore, the limiting cylinder of the vibration damping component is equipped with a detachable plug. When laying the crushed stone cushion layer, the plug is pre-embedded within the cushion layer, ensuring the upper surface of the vibration damping component is flush with the upper surface of the crushed stone cushion layer. Then, a tension rope is used to drive the plug from the limiting cylinder, creating an installation space. Reinforcing bars are then inserted into the limiting cylinder and spot-welded vertically to the vibration damping component. Next, the permeable concrete base layer is filled and leveled on the crushed stone cushion layer and covered with the reinforcing bars. Then, a reinforcing mesh, spot-welded to the reinforcing bars, is laid at the junction of the permeable concrete base layer and the permeable concrete surface layer. Finally, the permeable concrete surface layer is laid and compacted on the reinforcing mesh. The entire installation process is convenient and easy to operate, ensuring the practical effect of this invention. Attached Figure Description

[0023] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0024] Example 1

[0026] It also includes a connecting component 6 for connecting the crushed stone cushion layer 2, the permeable concrete base layer 3, and the permeable concrete surface layer 4. The connecting component 6 includes a plurality of vibration damping three-dimensional components 601 that are embedded at intervals in the upper inner side of the crushed stone cushion layer 2. The top of the vibration damping three-dimensional component 601 is fixedly connected to a steel bar 602 that penetrates the permeable concrete base layer 3 and extends to the top of the permeable concrete base layer 3. A corresponding steel mesh 603 is laid at the connection point between the permeable concrete base layer 3 and the permeable concrete surface layer 4, and the top of the steel bar 602 is fixedly connected to the steel mesh 603.

[0027] This utility model adds a corresponding connecting component 6 to the high-grade pavement. The connecting component 6 connects the load-bearing crushed stone cushion layer 2, permeable concrete base layer 3 and permeable concrete surface layer 4 of the pavement to form a whole, which enhances the strength of the pavement. When a vehicle passes over the pavement, it can not only disperse the force, but also effectively reduce vibration through the friction energy dissipation between damping particles when the vehicle resonates and is transmitted downward to the pavement, thereby achieving the effect of crack resistance.

[0028] The vibration damping three-dimensional component 601 is a sphere with a smooth arc-shaped outer surface and a hollow interior filled with damping particles 604. The damping particles 604 are spherical particles made of corrosion-resistant alloy material.

[0029] The upper surface of the vibration damping component 601 is planar, and a corresponding limiting cylinder 606 is fixedly installed inward from the middle of the upper surface. The limiting cylinder 606 is detachably plugged with a corresponding plug body 7. The top of the plug body 7 is higher than the top of the limiting cylinder 606, or a pulling rope for removing the plug body 7 is fixedly connected. When the vibration damping component 601 is embedded and fixed in the crushed stone cushion layer 2, its upper surface is flush with the upper surface of the crushed stone cushion layer 2.

[0030] After the vibration damping three-dimensional component 601 is embedded and fixed in the crushed stone cushion layer 2, the plug body 7 is taken out and the reinforcing bar 602 is inserted and fixedly connected in the limiting cylinder 606 and the permeable concrete base layer 3 is filled until the top of the reinforcing bar 602 protrudes from the upper surface of the permeable concrete base layer 3. Then, the reinforcing mesh 603 is laid on the upper surface of the permeable concrete base layer 3 and fixedly connected to the reinforcing bar 602.

[0031] Furthermore, a corresponding plug 7 is detachably and tightly installed at the limiting cylinder 606 of the vibration damping component 601. This plug 7 is pre-embedded within the crushed stone cushion layer 2 during installation, ensuring the upper surface of the vibration damping component 601 is flush with the upper surface of the crushed stone cushion layer 2. The plug 7 is then driven from within the limiting cylinder 606 by a tension rope to create an installation space. A reinforcing bar 602 is then inserted into the limiting cylinder 606 and vertically fixed to the vibration damping component 601 by spot welding. Next, the permeable concrete base layer 3 is filled and leveled on the crushed stone cushion layer 2, covering the reinforcing bar 602. Then, a reinforcing mesh 603, spot-welded to the reinforcing bar 602, is laid at the junction of the permeable concrete base layer 3 and the permeable concrete surface layer 4. Finally, the permeable concrete surface layer 4 is laid and compacted on the reinforcing mesh 603. The entire installation process is convenient and easy to operate, ensuring the practical effectiveness of this invention.

[0032] The top and bottom of the steel bar 602 are fixedly connected to the steel mesh 603 and the vibration damping component 601 respectively by spot welding, and the bottom of the steel bar 602 passes through the limiting cylinder 606 and extends to abut against the bottom of the vibration damping component 601.

[0033] The vibration damping three-dimensional components 601 are staggered, and the cross-sectional and longitudinal intersections of the steel bars 602 and the steel mesh 603 are fixedly connected.

[0034] Example 2

[0035] refer to Figure 5 The difference between this embodiment and Embodiment 1 is that the vibration damping three-dimensional component 601 is an ellipsoid with a smooth arc-shaped outer surface and is placed horizontally.

[0036] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0037] Example 3

[0038] refer to Figure 6The difference between this embodiment and Embodiment 1 is that the internal structure of the vibration-damping three-dimensional component 601 is hollow, and multiple vibration-damping plates 605 are fixed at intervals from top to bottom. Numerous corresponding vibration-damping micro-holes 6051 are evenly distributed on each vibration-damping plate 605, and through holes for penetrating the reinforcing bars 602 are coaxially arranged on each vibration-damping plate 605. When resonance occurs during vehicle travel and is transmitted downwards to the road surface, vibration energy dissipation and vibration reduction are achieved through the pores of the vibration-damping micro-holes in the vibration-damping plate 605, thereby achieving crack resistance.

[0039] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.
