Description

Vertical underground irrigation construction method and irrigation network management

The invention relates to an irrigation network pipe and an irrigation construction method, in particular to an irrigation network pipe for planting plants and an improved plant growth environment, and a vertical underground irrigation construction method using the irrigation network pipe.

In general cities or homes, in order to beautify the environment, various kinds of plants are usually planted at appropriate locations on the road or near the home. Farmers also plant various economic crops on the farmland, and the growth cycle of each plant varies. The growth cycle of peanuts and sweet potatoes is only a few months, and common street trees and fruit trees can usually survive for decades or even centuries. In general, plants with shorter growth cycles usually pass through the soil or the plants are withered, and the soil is softened by turning the soil, so that water and air can easily enter the soil, but for plants with longer growth cycles. It is said that since the roots of plants have been stretched around and cannot change the compactness of the soil by turning soil, the growth environment of this type of plants is usually harsh.

Taking common street trees as an example, street trees are usually planted on the sidewalks. In order to facilitate pedestrians, street tiles are usually laid around the street trees. When the soil around the street trees is exposed to the sun and rain, the surface of the soil layer will slowly change. Hard, not only does moisture and air not easily penetrate the hard surface of the soil layer, but the roots of the plant also do not have enough air and moisture. In this harsh growth environment, street trees usually have problems with growth retardation, which can lead to wilting in severe cases. In some road trees, in order to obtain the moisture and air required for growth, the roots will bulge and cause road surface protrusion and unevenness. That is, burrowing holes on sidewalks or farmland, and burying the roots of plants in caves, although the purpose of planting plants can be achieved, such construction methods will accelerate the deterioration of the environment due to the accumulation of time for plants. Not conducive to the growth of plants.

The half thickness L described in this embodiment means half of the thickness of the spiral reinforcing tape 12.

The spiral ring groove 14 has a converging section 141 corresponding to the fixed base 121 of the spiral reinforcing band 12, and a conical section 142 corresponding to the radial protrusion 122 of the spiral reinforcing band 12, due to the spiral reinforcing band The radial protrusion 122 has the spiral inclined surface 123, so the tapered expansion section 141 is extended from the side adjacent to the converging section 141 to the radially outer end, that is, the conical expansion section 141 is an outer portion. A space that is narrow in width and approximately trapezoidal in cross section.

Referring to Figures 2, 4 and 5, the vertical subsurface irrigation construction method of the present invention is used to improve the growth environment of a plant which is planted on a soil layer 3 and has a trunk which protrudes from the surface layer 30 of the soil layer 3. A canopy above the trunk and extending to the periphery, and a root deep below the surface 30. Generally, the expanded area of the plant root is equivalent to the outward expansion of the canopy.

The irrigation construction method of the embodiment comprises a burrowing step and a burying step. In the burrowing step, a plurality of vertical tube holes 31 adjacent to the root of the plant are excavated on the soil layer 3, and the number and position of the vertical tube holes 31 are determined according to the size of the plants, that is, the vertical tubes The pockets 31 can be one, two, or several of the embodiments disclosed, preferably determining the location of the vertical pockets 31 based on the average width of the canopy of the plant.

Specifically, when the average width of the crown is 20 cm, the embodiment only needs to dig one of the vertical holes 31. When the average width of the crown is increased to 36 cm, the embodiment excavates two intervals. Preferably, the vertical tube hole 31 is better. When the average width of the crown is expanded to 60 cm, it is preferable to excavate three of the vertical tube holes 31. If the average width of the crown is expanded to 90 cm, it is preferably Four of the vertical pockets 31 are excavated on the soil layer 3. In order to achieve a better irrigation effect, the vertical pocket 31 is located in the area covered by the crown, preferably in the middle of the canopy edge and the trunk. In order to obtain sufficient moisture and air for the root, the depth of the vertical tube 31 in this embodiment is preferably comparable to the depth of the root of the plant.

In the embodiment, the pipe laying step is to embed the irrigation net pipe 1 having the above structure in each corresponding vertical pipe hole 31. After the embedding, the top edge of the irrigation net pipe 1 is slightly lower than the soil layer 3 The surface 30, and then a plurality of bottom permeable basin covers 4 are respectively placed over each of the irrigation net pipes 1. After installation, the top edge of the basin cover 4 is substantially flush with the surface 30 of the soil layer 3. . Next, the gravel is placed inside the basin cover 4, that is, the irrigation construction method of the embodiment is completed.

In the present embodiment, the basin cover 4 is used. It is a general flower pot or a similar structure.

In this embodiment, after the construction is completed, the user pours water or nutrient solution into the basin cover 4, and the fluid such as liquid and air flows into the corresponding irrigation network tube after passing through the gravel. The irrigation channel 13 of 1 is finally infiltrated into the soil layer 3 by the mesh 113 of each irrigation network pipe 1. Since the irrigation network pipe 1 is adjacent to the root of the plant, the aforementioned irrigation construction method can be used less. Under the premise of water and nutrient solution, better irrigation effect is achieved. At the same time, air can also enter the soil layer 3 from the irrigation channel 13 of each irrigation network pipe 1, so that the root of the plant can obtain sufficient moisture, nutrients and air for a long period of time, and therefore, the construction method can be greatly improved in this embodiment.

The material does not flow into the corresponding irrigation channel 13 of the irrigation mesh tube 1 through the basin cover 4 to ensure that the irrigation channel 13 maintains better patency.

On the other hand, the irrigation net pipe 1 erected inside the soil layer 3 is surrounded by sand, but the irrigation net pipe 1 described in this embodiment not only has a mesh 113 having a hole diameter of less than 9 mm ² , and the irrigation net pipe In addition to having better pressure resistance, the spiral reinforcing tape 12 of 1 can also exert a better sand-blocking effect, that is, the spiral ring groove 14 of the irrigation mesh tube 1 of the embodiment has a width smaller than that of the converging section 141. The width of the tapered section 142, wherein the tapered section 142 is interposed between the spiral slopes 123, so that the whole is like a funnel with a narrow outer width and a half width L and a circumferential groove depth H. The dimensional cooperation can also generate resistance during the process of sand grain accumulation, that is, when sand is accumulated in the spiral ring groove 14, the closer the pressure is to the wall portion 11 of the mesh tube, the compactness of the sand grains is slightly The present invention can prevent the sand particles from entering the irrigation channel 13 through the meshes 113. Therefore, the structure and size of the spiral ring groove 14 of the present embodiment can better shield the sand. effect.

Referring to Figure 6, the structure of a second embodiment of the irrigation mesh tube 1 of the present invention is similar to that of the first embodiment, except that the shape of the spiral reinforcing strip 12, and the depth H of the annular groove and the half thickness L are The ratio between the two, that is, the spiral reinforcing tape 12 of the second embodiment has a spiral end face 125 connected to the outer end of the spiral bevels 123 in addition to the spiral bevel 123.

It can be seen from the above description that the structure of the irrigation net pipe 1 of the present invention is not only novel, but also has good pressure resistance while being vertically embedded in the soil layer 3, in addition to good irrigation and ventilation effects. The rate at which sand flows into the irrigation channel 13 is slowed to ensure that the irrigation mesh 1 maintains a better and lasting irrigation benefit.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
