Document Type and Number:
Japanese Patent JP3909184
Kind Code:

Abstract:

PROBLEM TO BE SOLVED: To provide a network body and a tubular body thereof which are excellent in pressure resistance, of which the thickness is reduced little in the amount even under large weighting and which hold voids and can discharge overflow water quickly, in the use wherein a compressive load is given in the direction of thickness, or others, and to provide the network body which is bendable, light in weight and excellent in handling properties and which has an improved soil filling property and has high versatility.
SOLUTION: A network forms a pleat-like section and has a plurality of ridge parts and ditch parts continuous in one direction, and the filament occupied area of the network occupying each vertex portion of the network is made minimum, while the filament occupied area of the network occupying a lateral wall portion between the respective vertex portions of the ridge parts and the ditch parts is made maximum. The vertex portions are fixed and joined by a plane body. Thereby structures having triangular sections each having one base side formed of the plane body and two oblique sides constituted of the portions of the network, viewed from the section in the direction of the thickness thereof, are formed in juxtaposition.
