For example, if the wheel is often crushed, the height of the second stage section 132 can be increased, but if it is located in a non-wheel rolling area, The height of the second stage section 132 can be reduced.
Incidentally, the so-called grading refers to the size distribution of the particle size of the material, which generally limits the ratio of the size of the various materials used in the engineering application, and meets or approximates the percentage of the mesh passing percentage of the engineering specification. Often referred to as a grading material. That is, as long as the engineering specification requires the particle size distribution of the material particles, the material is regarded as a graded ingredient, and the common gradation is as follows: soil, pellet and earth and stone mixture.
In this embodiment, the planting layer 14 has a plurality of laying objects 141 disposed adjacent to each other and having high pressure resistance. Each of the laying objects 141 has a planting space 142, such as a grass frame or a grass brick, The height is preferably 5 cm.
The irrigation drainage device 2 of the present embodiment comprises a plurality of water seepage network tubes 21 respectively installed in the first trenches 114 of the parking lot 1, a water inlet unit 22 connected to the isotonic water network tube 21, and a water seepage unit The drainage unit 23 is connected to the mesh tube 21. Each water permeable network tube 21 has a permeable portion 211 extending horizontally downward and extending along the length direction, a closed portion 212 connected to the permeable portion 211, and a partition defined by the permeable portion 211 and the closed portion 212. The passage 213 has a plurality of permeate holes 214 penetrating therethrough and communicating with the passage 213. The cross-section of the water-permeable mesh tube 21 of the present embodiment is not particularly limited, that is, the cross-section of the water-permeable mesh tube 21 may be circular, square, triangular or hexagonal except for the semi-circular shape as disclosed in the embodiment. The octagonal shape and the like are different shapes, but the shape of the cross section is preferably a semicircular shape disclosed in the embodiment, that is, the closed portion 212 of the water permeable mesh tube 21 of the embodiment is an elongated arc shape.
In the present embodiment, the water inlet unit 22 has an inlet pipe 221 installed in one of the second trenches 115 and communicating with the passage 213 of the isotonic network pipe 21, and a water inlet pump connected to the inlet pipe 221 222. The drain unit 23 includes a water level adjusting tank 231, and a drain pipe 232 connecting the water level adjusting tank 231 and the water permeable network pipe 21, and the drain pipe 232 is installed on the other of the second ditches 115. In the design, the water level adjusting tank 231 can be directly discharged to the drain as needed, or can have a water storage function, and is connected to the water pump 222 of the water inlet unit 22, that is, the water pump 222 in this embodiment can be In addition to other water source connections, the water storage of the water level adjusting tank 231 can also be fully utilized to achieve the purpose of making full use of the water source. In addition, in terms of water supply, the present invention can be used as the power supply water supply by using the water pump 222, and the power can be automatically powered by the power difference. Therefore, the present invention is not designed to have the same. The feed water pump 222 is limited.
Referring to Figures 1, 2 and 4, in the embodiment, the construction space 112 is first constructed on the original soil layer 11 of the parking lot 1, and then the bottom made of non-woven material is laid inside the construction space 112. The layer 12 is then erected above the bottom layer 12, the water inlet conduit 21, the inlet pipe 221 and the drain pipe 232. In order to improve the drainage function, the height of the water permeable network pipe 21 is preferably lowered from the one end adjacent to the water inlet pipe 221 to the lower end of the drain pipe 232, that is, the installation height of the drain pipe 232 is slightly lower. At the installation height of the inlet pipe 231, the liquid can be directed to the drain pipe 232 located at a lower position. Next, a permeable medium is backfilled in the construction space 112 to form the water permeable base layer 13.
The form of the permeable medium described in this embodiment is not particularly limited, and may be a gradation of different thickness, sand, sand, or the like. The permeable medium filled in the first trenches 114 in the present embodiment is a gradation having an average particle diameter of 1/4 inch, that is, the first grading segments 131 of the embodiment are composed of a plurality of gradations. The water-permeable medium of the second-stage distribution section 132 is a gradation of an average particle diameter of 3 inches, and the water-permeable medium of the root growth section 133 is sand. Of course, the average particle diameter can also be about 3/4~3/8. In the grading of the inch, that is, in the construction method of the present embodiment, the water-permeable base layer 13 is formed by using a gradation of different particle diameters and sand. Finally, the planting layer 14 of the plantable plant can be constructed by using the laying objects 141 above the water permeable base layer 13, and the laying object 141 can be laid by grading in addition to the grass frame or the grass planting brick.
When the irrigation drainage system is in use, parking spaces and lanes may be drawn above the phytosanitary layer 14, and the parking spaces and lanes may be distinguished by using the laying objects 141 or planting vegetation. On rainy days, rainwater may fall through the gap between the articles 141 and the planting space 142 of each of the articles 141 to the underlying water permeable base layer 13 and then into the first trenches 114. When the rainwater flows around the isotonic water network pipe 21, it flows into the channel 213 through the permeation hole 214 of the water permeating mesh pipe 21, and flows to the lower position drain pipe 232, and finally flows to the water level regulating pool. Storing in 231, since the water permeable network pipe 21 is buried in the first-stage distribution section 131 formed by the grading, the gradation does not block the penetration holes 214 of the water permeable network pipe 21 facing downward, so The service life of the water permeable network pipe 21 can be increased. That is, the irrigation drainage system of the embodiment can quickly remove the accumulated water on the surface of the original soil layer 11, and not only ensures that the surface of the parking lot 1 is dry, Without water accumulation, since the surface of the parking lot 1 is free from moisture, it can also prevent mosquitoes and weeds from growing, so as to improve the environment and cleanliness.
In general, the embodiment can use the water inlet unit 22 to send water of water or fertilizer to the isotonic network pipe 21, since the water permeable base layer 13 and the phytic layer 14 are both in a non-raining period. It is relatively dry, so that when the fed water or liquid fertilizer is oozing out from the permeate holes 214 of the isotonic network tube 21, the water-permeable base layer 13 which moisturizes the root group region of the adjacent plants can be osmotic. Therefore, the embodiment can achieve the purpose of irrigating plants while keeping the surface of the phytic layer 14 dry and avoiding the breeding of mosquitoes and weeds. When the plants are irrigated, since the liquid does not penetrate into the parking spaces and lanes for parking the vehicles, the ground is not slippery when the plants are irrigated, that is, the embodiment can keep the surface dry and dry, Plants are irrigated.
Further, in order to actually test the drainage and irrigation effects of the present invention, the inventors conducted field tests. In terms of drainage, the present invention constructs the construction space 112 on a 100 X 100 m 2 sandy land, and lays the bottom layer 12, erects the irrigation drainage device 2, lays the water permeable base layer 13, and lays the phytic layer 14 . The buried infiltration mesh tube 21 has a diameter of 4 inches, and the buried infiltration mesh tube 21 has a total length of 2210 meters and a depth of 60 cm. The first trench 114 has a groove width of 0.2 meters. After that, the water is evenly sprinkled at the test site. The water supply is 10 metric tons per minute, which is equivalent to 60 tons of heavy rainfall per hour. As a result of the test, the surface does not accumulate water in about 4 minutes, so the present invention does have an excellent drainage function.
In terms of irrigation, the configuration and arrangement of the irrigation and drainage device 2 The water test is the same, but water is sent from the inlet pipe 221 to the permeate network pipe 21, and then the permeability of the soil surface is observed. The experimental record is shown in the following table. From the experimental results, the present invention also has the surface of the parking lot 1 secured. Dry effect.
Referring to Figure 5, a second embodiment of the irrigation drainage system of the present invention is constructed similarly to the first embodiment, except that the irrigation drainage device 2 further includes a plurality of support conduits arranged in close proximity to the isotonic network conduit 21. 24, and a piece of mesh cloth 25 laid on the support network tube 24 and the water-permeable network tube 21, the support network tube 24 is a tube structure with a transparent through-hole and a square cross section, and the height is not lower than the water-permeable network tube 21, the purpose is to prevent the water permeable network pipe 21 from being crushed by the upper weight to extend the service life of the water permeable network pipe 21. That is, in the present embodiment, the supporting mesh tubes 24 are laid in the construction space 112 together with the isotonic water network tube 21.
However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, according to the present invention. The simple equivalent changes and modifications made by the scope of the patent application and the contents of the patent specification are still within the scope of the invention.
