The application of permeable concrete in pavement paving has received increasing attention, mainly because it can effectively manage rainwater and reduce urban runoff and waterlogging problems.

[0003] After retrieval, a patent with the Chinese patent application number CN206666965U discloses a permeable concrete pavement for a non-motor vehicle lane, which includes a bottom load layer, a filter layer, an upper load layer, and a concrete surface layer from bottom to top; the bottom load layer is a natural rammed foundation, the filter layer is a geotextile, and multiple grooves are arranged at intervals in the filter layer;

[0004] Although the above patent has multiple all-permeable panel bodies made of permeable concrete, a steel mesh is arranged in the all-permeable panel body to improve strength. And rectangular outer frames that cooperate with each other are respectively arranged around the all-permeable panel body. A plurality of arc-shaped protrusions and grooves are arranged on the periphery of the outer frame, and the protrusions and grooves are in conformity with each other in shape and size to form interlocking, which is not only conducive to construction and assembly, but also a plurality of permeable joints are formed between the outer frames after paving, which can improve the drainage efficiency. However, there are still the following deficiencies in the use process: 1. It cannot use rainwater to irrigate the green belt, and the prior art cannot distribute rainwater to the greening soil or drain it according to the amount of precipitation; 2. When the rainfall is too large, the drainage effect is poor, which is easy to cause waterlogging on the road surface.

[0005] Therefore, there is an urgent need for a permeable concrete pavement for a non-motor vehicle lane to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a permeable concrete pavement for a non-motor vehicle lane to solve the problems raised in the above background art.

[0008] A gravel layer is arranged at the bottom of the greening soil layer, a geotextile is arranged at the bottom of the gravel layer, and a compacted base layer is arranged at the bottom of the geotextile;

[0009] A shunt and voltage-dividing component, the shunt and voltage-dividing component includes a diversion layer disposed inside the filtering layer, the diversion layer includes symmetric shunt nodes, and there are multiple groups of the shunt nodes, and the shunt nodes are connected by diversion pipes;

[0010] An adaptive shunt component, disposed on both sides of the filtering layer.

[0011] Further, the adaptive shunt component includes a shunt plate rotatably connected to both sides of the filtering layer, and one end of the shunt plate away from the filtering layer abuts against the greening soil layer, and a spring is fixedly connected to the outer wall of the shunt plate, and one end of the spring away from the shunt plate is connected to the filtering layer.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] In the solution of the present application:

[0017] 1. By arranging the shunt plate to abut against the greening soil layer, the rainwater will flow into the space formed between the spacer plates, that is, the space where the shunt plate is located, through the filter plate. When the rainwater is less, the elastic force of the spring is greater than the pressure of the rainwater weight, and the rainwater will respectively flow into the greening soil layer through the permeable brick layer and the shunt plate, preferentially supplying water to the greening soil layer. When the water permeating the greening soil layer presents a water accumulation state, the elastic force of the spring is less than the pressure of the rainwater weight, so it contracts under force, that is, the shunt plate will rotate and open the channel formed between the filtering layer and the greening soil layer, so as to discharge the excess rainwater, and the greater the precipitation, the larger the channel opened by the rotation of the shunt plate, adaptively distributing the rainwater according to the precipitation amount to the greening soil and discharging it, solving the problems in the prior art that the rainwater cannot be used to irrigate the green belt, and the prior art cannot distribute the rainwater to the greening soil or discharge it according to the precipitation amount.

[0018] 2. Rainwater is made to flow through multiple diversion nodes, and is separately dispersed through diversion pipes and finally concentrated on the lower diversion nodes, which correspond to the water collection openings. That is, finally, it is discharged into the diversion support frame through the water collection openings and then discharged, improving the drainage efficiency, sharing the drainage pressure of a certain node, and being an embedded built-in structure, which does not affect the firmness of the road structure and can save land resources, solving the problem in the prior art that when the rainfall is too large, the drainage effect is poor and it is easy to cause waterlogging on the road surface.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0028] Such as Figure 1-6As shown in the figure, a permeable concrete pavement for non-motorized lanes proposed in this embodiment includes a permeable concrete layer 1. A filter layer 2 is provided at the bottom of the permeable concrete layer 1. The filter layer 2 can quickly guide water flow to the lower layer or the drainage system, reduce surface runoff, and reduce water accumulation. Greening soil layers 9 are symmetrically arranged on both sides of the permeable concrete layer 1. A permeable brick layer 10 is provided on the top of the greening soil layer 9. The permeable brick layer 10 has water permeability, facilitating rainwater to penetrate into the greening soil layer 9 for the vegetation in the greening soil layer 9 to use. It also includes:

[0029] A gravel layer 4 is arranged at the bottom of the greening soil layer 9. A geotextile 5 is provided at the bottom of the gravel layer 4. A compacted base layer 6 is provided at the bottom of the geotextile 5. The compacted base layer 6 can increase the bearing capacity of the foundation, provide a strong and stable support for the upper permeable concrete, and prevent future settlement and deformation;

[0030] A flow splitting and pressure dividing component. The flow splitting and pressure dividing component includes a diversion layer 3 arranged inside the filter layer 2. The diversion layer 3 includes symmetric diversion nodes 12, and multiple groups of diversion nodes 12 are provided. The diversion nodes 12 are connected by diversion pipes 13. When the rainwater is too large, the rainwater flows through the permeable concrete layer 1 and filters through the filter layer 2. The filter layer 2 contains substances with a strengthening structure to strengthen the firmness of the road surface and prevent cracking. When the rainwater flows into the diversion layer 3 through the filter layer 2, the diversion layer 3 is composed of multiple diversion nodes 12. When the rainwater volume at a certain diversion node 12 is too large, the drainage pressure can be shared to the other diversion nodes 12 through the diversion pipe 13, thereby reducing the pressure at a certain node and preventing water accumulation at a certain place due to excessive precipitation. Finally, it converges on the lower diversion nodes 12. The diversion nodes 12 correspond to water collection ports 16, and then it is discharged into the diversion support frame 8 from the water collection ports 16 and finally discharged;

[0031] An adaptive flow splitting component is arranged on both sides of the filter layer 2.

[0032] Such as Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, the adaptive flow splitting component includes flow splitting plates 17 rotatably connected to both sides of the filter layer 2, and one end of the flow splitting plate 17 away from the filter layer 2 abuts against the greening soil layer 9. A spring 18 is fixedly connected to the outer wall of the flow splitting plate 17, and one end of the spring 18 away from the flow splitting plate 17 is connected to the filter layer 2. When the rainfall is small, the rainwater passes through its filter plate 14 and flows into the channel formed between the filter layer 2, the greening soil layer 9 and the spacer plate 11. At this time, the flow splitting plate 17 is pushed by the elastic force of the spring 18 to abut against the greening soil layer 9, and the rainwater will penetrate into the greening soil layer 9 through the flow splitting plate 17 and gradually accumulate. When the rainwater accumulates too much, when the elastic force of the spring 18 is less than the pressure generated by the rainfall on the flow splitting plate 17, the flow splitting plate 17 will rotate to a certain extent, that is, open the channel formed between the greening soil layer 9 and the filter layer 2, so as to discharge the excess rainwater. When the rain is heavy, this effect is more obvious, and it can flexibly adapt to large and small rainwater to achieve the distribution of rainwater.

[0033] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a number of evenly distributed sealing support plates 7 are provided between the filter layer 2 and the gravel layer 4. A diversion support frame 8 is also provided between the filter layer 2 and the gravel layer 4, and the diversion support frame 8 is fixedly connected to the sealing support plate 7. The diversion support frame 8 is provided with evenly distributed water collecting ports 16, and the water collecting ports 16 correspond to the diversion nodes 12 located at the bottom. A flow channel 15 is provided between adjacent sealing support plates 7. The flow channel 15 facilitates the concentration of rainwater into the diversion support frame 8, thereby facilitating the discharge of rainwater. The diversion support frame 8 and the sealing support plate 7 are an internal support structure, which is convenient for guiding and discharging rainwater, and at the same time strengthens the stability of the structure.

[0034] As Figure 5-6 shown, as a preferred embodiment, on the basis of the above method, further, a number of evenly distributed spacer plates 11 are provided between the filter layer 2 and the greening soil layer 9, and the spacer plates 11 are fixedly connected to the sealing support plates 7. A filter plate 14 is provided on the top wall of the spacer plate 11, and the filter plate 14 is used to filter debris such as leaves in the rainwater.

[0035] As Figure 5 shown, as a preferred embodiment, on the basis of the above method, further, the flow splitting plate 17 is located between adjacent spacer plates 11, and the flow splitting plate 17 opens and closes the space formed between the spacer plate 11, the greening soil layer 9 and the filter layer 2.

[0036] Specifically, when this permeable concrete pavement for non-motorized lanes is in use: when the rainfall is small, rainwater passes through its filter plate 14 and flows into the channel formed between the filter layer 2, the greening soil layer 9 and the spacer plate 11. At this time, the diversion plate 17 is pushed by the elastic force of the spring 18 to abut against the greening soil layer 9, and the rainwater will penetrate into the greening soil layer 9 through the diversion plate 17 and gradually accumulate. When the rainwater accumulates too much, when the elastic force of the spring 18 is less than the pressure generated by the rainwater volume on the diversion plate 17, the diversion plate 17 will rotate to a certain extent, that is, open the channel formed between the greening soil layer 9 and the filter layer 2, so as to discharge the excess rainwater. When the rain is heavy, this effect is more obvious, which can flexibly adapt to large and small rainwater and realize the distribution of rainwater. At the same time, if the water in the greening soil layer 9 accumulates too much, it can also be discharged through the diversion plate 17 to prevent the rainwater from accumulating too much and causing the greening vegetation to be flooded, realizing a balanced water supply efficiency. At the same time, when the rain is too heavy, the rainwater flows through the permeable concrete layer 1 and filters through the filter layer 2. The filter layer 2 contains substances with a strengthening structure to strengthen the firmness of the road surface and prevent cracking. When the rainwater flows into the diversion layer 3 through the filter layer 2, the diversion layer 3 is composed of multiple diversion nodes 12. When the rainwater volume at a certain diversion node 12 is too large, the drainage pressure can be shared to the other diversion nodes 12 through the diversion pipe 13, so as to reduce the pressure at a certain node and prevent waterlogging at a certain place due to excessive precipitation, and finally gather at the diversion node 12 located at the lower part. The diversion node 12 corresponds to the water collecting port 16, and then is discharged into the diversion support frame 8 from the water collecting port 16 and finally discharged. The diversion support frame 8 and the sealing support plate 7 are internal support structures, which are convenient for guiding and discharging rainwater and strengthening the stability of the structure.

[0037] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
