JPH1146584A - Laminated body unit for greening desert - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a laminated unit for greening a desert, by forming the body into a unit structure so that the number of the units may be structurally readily increased as an area to realize greening of the wide desert zone more effectively and economically, and to form a stable soil environment in which a plant can readily grow even in a special environmental state of the desert. SOLUTION: This laminated unit for greening a desert has a hexahedron frame 1 having extremely fine wire gauze 2 and an oxygen-supplying wall 9 composed of the extremely fine wire gauze, and further a pebble layer 4, a sponge layer 5, a water retention fiber layer 6 and an earth and sand layer 8 with bean-like sponge 7 formed from the bottom of the body so as to form layers, and base stakes 3 and body-connecting metal fittings 10 formed in the exterior of the hexahedron frame 1 to form the laminated unit. The plural laminated units are connected to each other to extend the earth and sand layers 8, etc.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit system capable of greening plants and the like more effectively and economically in a desert. 2. Description of the Related Art Conventionally, in the case of rainfall in a desert, for example, rainfall easily penetrates downward and dries easily. In order to prevent evaporation, there is a method of burying a columnar structure having water retention and air permeability in sand to grow plants, or a method of preventing evaporation of sand ground with a waterproof film or the like. However, in order to achieve more effective and economical greening for the vast area of the desert and special environment, there are disadvantages and problems in the structure. [0003] The present invention is directed to a unit structure capable of easily increasing the main body in terms of structure and area in order to realize more effective and economical greening of a vast desert area. At the same time, it creates a stable soil environment where plants can easily grow even in the special environmental conditions of the desert. [Means for Solving the Problems] An ultrafine wire mesh 2 and an ultrafine wire mesh oxygen supply wall 9 are provided in a rectangular parallelepiped frame 1, and a pebble layer 4, a sponge layer 5, a water-retaining fiber layer 6, a bean-shaped layer are provided from the bottom of the main body. A sponge 7-containing earth and sand layer 8 is provided for lamination. Outside the rectangular parallelepiped frame 1, a foundation pile 3 and a main body connection fitting 10 are provided to form a laminate unit 1A, and a plurality of these are connected. [Embodiments of the Invention] Hereinafter, embodiments shown in the drawings will be described. [Structure] An extra-fine wire mesh 2 and an extra-fine wire mesh oxygen supply wall 9 are provided in a rectangular parallelepiped frame 1, and a pebble layer 4, a sponge layer 5, a water-retaining fiber layer 6, and a bead-like sponge 7-containing soil layer 8 are provided from the bottom of the main body. To be laminated. Further, outside the rectangular parallelepiped frame 1, a foundation pile 3 and a main body connection metal fitting 10 are provided to form a laminate unit 1A. By connecting a plurality of the laminate units 1A, the earth and sand layer 8 and the like can be enlarged. [Embodiment] An extra fine wire mesh 2 and an extra fine wire mesh oxygen supply wall 9 are provided in a rectangular parallelepiped frame 1 in advance, and a pebble layer 4, a sponge layer 5, a water retaining fiber layer 6, and a bean-like sponge 7 from the bottom of the main body. The layer 8 is provided and lamination is performed. Further, a foundation pile 3 and a main body connection fitting 10 are provided outside the rectangular parallelepiped frame 1 to form a laminate unit 1A, and a required number of bases are prepared and transported to a place designated in a desert area. Next, after digging the required area and depth of the place to be installed and providing the split stone 11, each laminated unit 1A is installed. After the installation is completed by checking the level and the like, a plant 12 is planted in each laminate unit 1A, and water and fertilizer are applied. [Effect of the Invention] Since the sponge layer 5 is provided in the rectangular parallelepiped frame 1, water can be retained for a long time after precipitation or irrigation, and water does not easily evaporate. In addition, since the water-retaining fiber layers 6 are provided above and below the earth and sand layer 8, the surface and the lower surface of the earth and sand layer 8 are hardly dried even at a high temperature in the daytime. Therefore, even if the soil is slightly dried, the bean-like sponge 7 maintains a water-absorbing state, and the moisture hardly evaporates. In the rectangular frame 1, an extra-fine wire mesh oxygen supply wall 9 is provided. Oxygen is supplied by ventilation to the plant roots, and root rot can be avoided. Further, the foundation pile 3 and the main body connection metal fitting 10 are provided outside the rectangular parallelepiped frame 1, so that the structure and area can be easily increased, and it can be easily fixed in sand. Since the desert greening laminate unit of the present invention has a functional unit structure, greening of the desert can be realized more effectively and economically.
