Description

Permeable grass paving underground water storage structure

Technical Field

The present invention relates to an underground water storage structure of a permeable grass pavement, in particular to a permeable grass pavement that can not only construct a disaster prevention type permeable grass pavement with the function of quickly draining rainwater, but also effectively store the drained rainwater in an underground water bucket structure for recycling and reuse.

Background Art

Since ancient times, soil has the function of collecting and retaining water. However, due to the continuous development and expansion of cities, the large-scale construction of various artificial facilities has led to a continuous increase in impermeable pavement, causing the catchment area to gradually lose its original water retention capacity and a significant increase in surface runoff. Coupled with the impact of global climate change, urban areas are facing greater flood control pressure.

Therefore, in order to reduce the environmental burden and the negative impacts it causes, many cities have proposed corresponding adaptation measures and sustainable development policies in recent years, such as promoting the sponge city policy, which is a new urban model that builds flood control and waterlogging prevention functions in the city and has ecological and environmental protection functions. For example, permeable pavement is built to replace non-permeable pavement, which absorbs, stores, infiltrates and purifies water when it rains, and releases and utilizes the stored water when needed.

In view of this, the inventor of this case actively researched and designed a system to meet the above needs, and after careful evaluation, finally obtained a truly innovative and practical invention.

Summary of the invention

The main purpose of the present invention is to provide a permeable grass-planted pavement underground water storage structure, which can quickly drain rainwater from the surface pavement into the ground, and store and retain it at the same time, which can not only reduce the chance of surface floods, but also replenish groundwater for subsequent use, so as to achieve the effect of sufficient water storage and recycling rainwater resources for reuse.

To achieve the above-mentioned purpose, the present invention provides a water-permeable grass-planted pavement underground water storage structure, which comprises a frame board pavement material and a water piggy bank structure, and is characterized by:

The frame board material mainly has a plurality of raised boxes on the frame board material, and the boxes are hollow, have an open bottom and a closed top, and have a breakthrough structure on the top;

The water-saving structure is buried under the frame board and is composed of a plurality of porous hollow units.

Thus, when the concrete mortar is poured and coated on the frame board paving material and solidifies to form a floor paving surface, the top of the box body is broken to construct a permeable grass-planting paving surface with multiple grass-planting holes.

The effective benefit of the present invention is that the grass planting hole can be filled with soil for planting or filled with sand, gravel and ground materials, thereby quickly draining the ground water into the ground, which can not only effectively prevent the chance of surface floods, but also replenish groundwater resources. At the same time, it can also form a water storage space in the water bank structure to store and recycle rainwater for subsequent reuse.

Other features and specific embodiments of the present invention can be further understood from the following detailed description with reference to the accompanying drawings.

DETAILED DESCRIPTION

1 to 6 , the underground water storage structure of the permeable grass-planted pavement of the present invention includes a frame paving material 10 for pouring concrete mortar to form a floor pavement and a water bank structure 20 .

The frame board paving material 10 is made of plastic, lightweight concrete, high-strength concrete (GRC), recycled plastic materials (such as PVC, ABS, PP) or recycled paper materials, etc. It is mainly provided with a plurality of raised boxes 12 on the board body 11, each box body 12 is set to be hollow, with an open bottom 121 and a closed top 122, and an easy-to-implement breakthrough structure 123 is provided on the top 122. The breakthrough structure refers to the easy processing of the closed top 122 into an open state by simple manual tools, as shown in Figure 7. The so-called top 122 shape includes making the top board thinner and easy to break during secondary processing. In another feasible embodiment, the breakthrough structure 123 on the top 122 of the box body 12 is set as a circular groove, as shown in Figure 7A. The groove of the breakthrough structure 123 is shown to be arranged on the top surface of the closed top plate 122. If the circular groove is arranged on the bottom surface of the closed top plate 122, that is, at the junction of the top of the inner wall of the box body 12, the same effect can be obtained.

The inner wall of the box body 12 is designed to be inclined to facilitate demoulding during manufacturing, and it is also easier to stack the materials when preparing and storing them to reduce the volume. A concrete feeding trough 13 is also provided on the plate body 11 of the frame board paving material 10, so that the concrete can flow down to the crushed stone grading layer below. When the concrete solidifies, it becomes a similar anchor structure with a gripping effect, making the paving foundation less likely to slide, achieving a more stable connection effect of the ground surface foundation anchor.

The water-bank structure 20 is composed of at least one porous hollow unit body 20a or a plurality of units assembled together, and is coated with a layer of non-woven fabric 30 on the outside to prevent mud and sand from flowing into the water-bank structure 20. In addition, if in different geological regions, the water-bank structure 20 may be directly buried underground at a predetermined location without being coated with the non-woven fabric 30.

In addition, in the preferred embodiment shown in the figure, the hollow unit body 20a is composed of a pair of upper and lower symmetrical stacking bricks 21 and a side plate 22 also having a plurality of through holes 221. The stacking brick 21 is provided with an upper plate at the top, and a groove is provided on the upper plate, and a concrete mortar pouring flow material through pipe 212 is provided in the groove, as shown in Figure 3. In this embodiment, the grooves are set as two, and a better setting method is to set the grooves in a cross shape, and the grooves are set at the center of the upper plate of the stacking brick 21 at the staggered position, and the concrete mortar pouring flow material through pipe 212 is set at the staggered position and extends downward. A plurality of through holes 211 are provided on the upper plate at the top of the stacking brick 21, so that water can penetrate into the upper plate at the through holes 211. A plurality of support columns 213 are formed by protruding from the other side of the upper plate. Corresponding protrusions 214 and grooves 215 are provided at the ends of each support column 213, so that the upper and lower stacking bricks 21 can be fixed to each other when combined, and can also provide support for the interior of the hollow unit body 20a. In addition, a plurality of engaging grooves are provided around the upper plate of the stacking brick 21. 216, a clamping assembly 217 is provided, as shown in FIG6; two adjacent hollow unit bodies 20a are firmly spliced together by inserting buckles, and the four sides of the upper plate of the brick 21 are also provided with relatively buckled convex tenons 218 and mortise grooves 219, and two adjacent brick blocks can be spliced together by mortise and tenon 218 and mortise groove 219, and the outer side surfaces of the outermost hollow unit bodies 20a are overlapped and sealed by the side panels 22 to form the water bank structure 20.

Please refer to FIG. 5 again. The water-saving structure 20 used in the present invention has a groove on the upper plate of the brick 21. A steel bar 31 can be added in the groove. Then, concrete mortar 40 is poured on the upper side of the brick 21 and smoothed. At the same time, the concrete mortar is poured into the flow material pipe 212, so that the concrete in the water-saving structure solidifies to form a strong beam and column structure, which has a high load-bearing support effect.

Please refer to Figures 6 to 9 again. During implementation, the water bucket structure 20 can be a general water bucket or a water bucket with a groove on the top as shown in the diagram of this embodiment. First, land preparation is performed on the floor where the permeable grass pavement A is to be constructed. According to the overall sponge city planning blueprint, the water bucket structure 20 can be coated with a non-woven fabric 30 or not coated and directly arranged in the underground soil layer B according to a predetermined position. Then, a primary distribution layer C is laid on the construction area where the pavement is to be constructed. The grading layer C can be made of local existing earthwork or general road engineering grading materials, including sand, gravel, soil, or soil. Then, a grouting operation is performed to pour concrete mortar on the frame paving material 10, compact and smooth it, and make it flush with the top edge of the box body 12.

In addition, during the grouting operation, plastic steel bars or steel bars can be placed between the boxes 12 of the frame paving material 10 to obtain higher solidity and toughness after grouting. The method of using concrete mortar to grout the frame paving material 10 can also replace the concrete mortar with permeable concrete or crushed stone mortar or asphalt or permeable asphalt.

After the concrete slurry solidifies, a simple tool can be used to directly break the breakthrough structure on the top 122 of the box body 12 to form a permeable grass-planting pavement A with a plurality of grass-planting holes 14 .

In this way, the grass-planting hole 14 can be filled with water-permeable materials such as sandstone, ground materials, or filled with cultivation soil for planting flowers and plants, as shown in FIG9 ; in this way, the effect of planting grass and greening can be achieved. When heavy rain falls on the surface instantly, the grass-planting hole 14 can be used to quickly drain the rainwater on the ground to the ground, and the water storage space formed inside the water-saving structure 20 can quickly and massively store water, thereby achieving the probability of preventing regional floods in a relatively short time. After the rainwater on the ground surface stops infiltrating, it will slowly infiltrate into the underground soil layer B after a specific period of time to replenish the groundwater resources, thus achieving the function of effectively and quickly draining the ground and replenishing the groundwater in a short time.

If the ground is hot and hot, the underground contains a high water content. In addition to allowing the underground moisture to maintain the soil moisture in the grass planting hole 14, it can also improve the moisture retention of the graded layer C, making the graded layer C an ecological graded layer, which can provide a high-quality living environment for soil microorganisms and protozoa in the soil. Therefore, soil microorganisms can be used to decompose organic matter, promote nitrification, denitrify, improve soil quality, and other benefits to facilitate plant growth. At the same time, it can also be converted into water vapor and released to the outside to perform heat exchange in the environment, avoid the occurrence of the heat island effect, or slow down the heat island effect. At the same time, the water piggy bank structure 20 can also recycle the rainwater stored inside through the connection of pipelines for other subsequent uses, such as combining with a spraying system for road cooling or plant planting.

As can be seen from the above, the underground water storage structure of the permeable grass pavement of the present invention has the following practical advantages:

1. It can reduce surface runoff and the chance of floods. It can also replenish groundwater resources, which not only achieves the purpose of water conservation in the base, but also releases water vapor to exchange heat with the surface temperature, thereby regulating the overall temperature and humidity in the environment. It can effectively reduce the heat island effect, or avoid the occurrence of the heat island effect, and create a more efficient sponge city ecological environment.

2. It can effectively improve the structure and practicality of grass and tree planting surfaces, maintain the soil moisture in the grass planting holes, and activate the organic matter in the soil, which is beneficial to the growth of plants.

3. A large underground rainwater storage space can be provided for subsequent use, so as to achieve the effect of sufficient water storage and recycling rainwater resources for reuse.

4. The water piggy bank structure composed of a brick stacking form not only has high porosity and high support, but also has multiple characteristics such as light texture, small size and high reusability. It can make the construction more convenient and faster, shorten the construction period, reduce costs, and also has environmental protection effects.

5. The use of a frame paving material and an anchor structure formed by connecting the upper and lower parts to form a permeable grass paving surface can not only reduce maintenance and enhance strength and durability, but also prevent water and drought disasters, increase the greening area, prevent the heat island effect, reduce electricity consumption, and at the same time provide unlimited circulating water and reduce irrigation water costs.

In summary, the present invention uses a frame board paving material that can construct a permeable grass paving surface and a water piggy bank structure design to construct a sponge city road pavement with excellent quality, low cost, and both disaster prevention and underground water storage functions. It has industrial utilization value and a patent application is filed in accordance with the law. However, the above is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention; therefore, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention specification should still fall within the scope covered by the patent of the present invention.
