Description

Improved water permeable pavement structure

Technical Field

The present invention relates to an improved permeable pavement structure, and more particularly, to a design of an artificial permeable pavement structure capable of effectively and rapidly guiding rainwater on the ground by using simple permeable units.

Background

In general, the construction method of concrete pavement building is to pour a sufficient amount of concrete, level the concrete surface, and then lay the bricks forming the pavement to complete the construction of an artificial concrete pavement.

However, the traditional surface pavement is formed by concrete or concrete combined with brick bodies, the concrete generally has no water permeability, even if the concrete is water permeable, the hair gaps of the concrete are easily blocked, and the concrete bricks can generate calcium oxide to actively seal the hair gaps and cannot be cleaned, so that the water permeable efficiency is far lower than the speed of heavy rain falling, not only is a large amount of water accumulated on the surface easily caused, but also the falling rainwater cannot effectively supplement underground water sources, and only can be guided by drainage ditches to be collected in a rainwater sewer trunk pipe and then flow into the sea, and the waste of water resources is increased; or flow to low-lying areas to form flood disasters or damage lives and properties of people.

However, the impermeable pavement can prevent the soil under the ground from contacting the air layer on the ground, and under the condition that underground water resources cannot be effectively replenished, the water content of the soil is insufficient, so that the conditions of global warming, heat island effect and the like are gradually enlarged, which is undoubtedly a great harm to environmental protection, and the concrete pavement without the permeable structure is not ideal.

Therefore, there is a new construction method for water permeable pavement in the conventional technology, which mainly uses upper and lower connecting frames to erect a plurality of tubes to form a unit frame, and lays the unit frame above the gravel layer of the construction site, and pours concrete slurry into the unit frame to be embedded in the concrete slurry pavement layer, and forms a plurality of water discharge holes in the pavement layer through the tubes of the frame to construct a concrete water permeable pavement.

However, when the unit framework used by the permeable pavement is laid above the gravel layer, because the sectional area of the lower end opening of the pipe body in the framework is quite narrow, and workers also need to step on the framework frequently during construction, the condition that the sinking degree of each pipe body is different or even the pipe body is collapsed is easily caused, the finished surface after concrete slurry is poured is uneven, or the pipe body is buried by the concrete slurry and cannot play a role of water drainage, and the construction quality of the whole permeable pavement is further influenced. In addition, because the number of the components of the unit structure is large, not only more raw material resources are required to be consumed, but also the overall manufacturing cost is high, which is still not ideal.

In view of the above, the present inventor has made active research and design efforts to overcome the above-mentioned shortcomings, and has developed an improved design for a permeable pavement structure with lower cost and more enhanced structure.

Disclosure of Invention

The utility model mainly aims to provide an improved permeable pavement structure which can effectively strengthen the structure, the bearing capacity and the stability of permeable units of permeable pavement, further ensure the flatness of a grouting finished surface and further obtain better pavement construction quality.

Another object of the present invention is to provide an improved permeable pavement structure, which can effectively reduce the use of plastics and the overall manufacturing and construction costs, thereby improving the product competitiveness.

To achieve the above object, the present invention provides an improved permeable pavement structure, which is composed of a permeable unit and a plug template, and is characterized in that:

the water permeable unit is provided with a plurality of upright hollow tubular columns which are arranged at intervals, the outer edge of the lower port of each tubular column is respectively provided with an outward-expanding connecting rib, and the connecting ribs are mutually connected;

the plug cover template is covered above the water permeable unit in a grid shape, and plug columns are respectively and convexly arranged at the corresponding positions of the hollow tubular columns and are sleeved and fixed at the upper ports of the tubular columns;

therefore, the water permeable units are arranged above the gravel layer, the contact area of the lower end opening of each pipe column is enlarged by the connecting ribs at the bottom, the water permeable units can be stably and flatly laid above the gravel layer, and the plug cover template is removed after concrete slurry is poured, so that the water permeable pavement with the plurality of water drainage holes is constructed.

This neotype effective gain lies in through the improvement of this structure, can not only ensure this permeable pavement's construction quality, also can reduce the use of plastics and reduce whole manufacturing cost and sparingly make up artifical expenditure simultaneously with less structure component, increase product competitiveness.

Detailed Description

Referring to fig. 1 to 3, an improved permeable pavement structure of the present invention mainly includes a permeable unit 10 and a cover form 20.

The water permeable unit 10 has a plurality of upright hollow columns 11 arranged at intervals, and an outwardly extending connecting rib 12 is provided at the bottom edge of each column, and the connecting ribs 12 are connected with each other. Furthermore, when the present invention is implemented, the hollow pipe 11 can be designed into a tapered shape gradually shrinking from bottom to top, so that the pipe can form a chimney effect to enhance the air convection.

The expanded connecting ribs 12 are formed by extending plastic plates outward from the bottom ends of the hollow pipe columns 11 to form a disc shape, and then extending thin rod-shaped ribs outward, as shown in fig. 1, the thin rod-shaped ribs can also be directly extended outward from the bottom ends of the hollow pipe columns 11, or the expanded connecting ribs 12 can be made of plastic materials with different hardness.

The plug cover template 20 is covered on the water permeable unit 10 in a grid shape, and plugs 21 corresponding to the hollow pipe columns 11 are protruded from the bottom of the plug cover template for being sleeved on the upper ports of the pipe columns and sealing the pipe columns. In addition, the plug cover template 20 provided by the novel design can be provided with corresponding

joint parts

22 and 23 at the periphery or not at all. If the joint is provided, during actual laying, the

joint parts

22 and 23 of the plug cover formwork 20 can be used for corresponding each water permeable unit 10, so that the complete erection thereof has a structure with the same area as the pavement to be constructed, as shown in fig. 3; this completes the butt joint of the edges of the closure template 20 if no joint is provided, as shown in fig. 3.

Referring to fig. 1 to 4, in the illustrated embodiment, the water permeable unit 10 is further provided with a connecting frame 50 between the hollow columns 11, so that after the whole water permeable unit 10 is completely laid, and concrete grout is poured, a stronger concrete cast structure is obtained.

Referring to fig. 4 to 7, when constructing the water permeable pavement, the utility model is to tamper the ground layer of the construction area, such as the graded layer or the gravel layer 30, and then to assemble each water permeable unit 10 and the plugging template 20 above the gravel layer 30 in cooperation with the whole pavement area, so that in the whole construction process, not only can each hollow pipe column 11 and the connecting ribs 12 that are connected and expanded are placed on the gravel layer 30 to form a positioning effect, but also the concrete slurry can be prevented from seeping into the lower port of the hollow pipe column 11 along the periphery of the connecting ribs 12 to cause blockage, and meanwhile, a larger contact area is generated at the periphery of the hollow pipe column by the connecting ribs 12, so that the water permeable units 10 can be laid more smoothly and stably.

After the whole water permeable unit 10 is laid, concrete slurry filling operation is performed to fill the whole water permeable unit 10 with the concrete slurry 60, and the concrete grout is compacted and leveled to make the finished surface of the concrete grout level with the top edge of the plug cover template 20 at the top, as shown in fig. 5, after the concrete slurry is properly set and formed, the plug cover form 20 is removed, thereby forming a concrete permeable pavement layer 40, and forming a plurality of water discharge holes 41 penetrating to the gravel layer 30 on the surface of the concrete permeable pavement layer 40, the plugging template 20 is plugged at the upper port of the hollow pipe column 11 of the water permeable unit 10, so as to avoid the occurrence of sliding and plugging the pipe body by grouting concrete 60, meanwhile, a water guiding groove 42 communicated with each water discharging hole 41 is formed on the surface of the water permeable pavement layer 40, so that rainwater on the ground can be quickly and effectively discharged to the water discharging holes 41 and flows into the ground.

Referring to fig. 8, before grouting, when the present invention is used to combine the water permeable unit 10 and the plug cover form 20, in different embodiments, reinforcing steel bars 24 or a reinforcing mesh is disposed between the hollow pipe columns 11, so that after subsequent concrete pouring, a firmer concrete block layer is obtained, and the gravity of the pavement surface under the pressure of the traveling of the vehicle is improved.

From the above, the improved permeable pavement structure of the present invention has the following practical advantages:

1. the contact area of the lower port of the hollow pipe column is enlarged through the density of each connecting rib at the bottom of the water permeable unit, so that the integral bearing capacity is increased, the water permeable unit is more stable when being laid, and the phenomenon that the water permeable unit sinks or collapses when being trampled by constructors is avoided.

2. Ensure the roughness of this shop front completion face that permeates water, and then obtain better construction quality, promote the holistic drainage benefit of this shop front.

3. The usage amount of plasticizing raw materials is reduced by fewer structural components, and meanwhile, the whole manufacturing cost is also reduced, and the product competitiveness is increased.

In view of the above, the present invention achieves the intended purpose, brings practical benefits into full play, improves industrial utility values, meets the requirements of patent applications, and issues patent applications in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby; therefore, all the equivalent changes and modifications made in the claims and the contents of the specification should be covered by the scope of the present invention.
