摘要： PROBLEM TO BE SOLVED: To provide an erosion prevention mat used for the revetment of a river, which is capable of suppressing the runoff of soil for plants filled in the mat due to water flow through the river. SOLUTION: A number of continuous wire stripe bodies 15a with a diameter of 0.1 to 5 mm made of a thermoplastic resin polymer is respectively extended while intersecting each other in horizontal directions and thickness direction while bending irregularly from one side to the other, a number of many continuous wire bodies 15a are melted together at many intersecting points; and when the whole body is observed from one side to the other, they comprise a cubical net-shaped structural bodies 15 having wave-shapes where the projected portion and recessed portion are repeated at predetermined intervals and flexible net bodies 14 being attached either to the front or rear side in the cubical net-shaped structural bodies 15; and the continuous wire stripes take in longitudinal stripes and/or lateral stripes constituting the net body 14 thereby making the net bodies 14 and cubical net-shaped structural bodies 15 in one united bodies.

摘要： PROBLEM TO BE SOLVED: To provide an anchor member causing little slipping-away, and capable of playing a role for promoting seeding and planting even if the ground is weak, and even when an inclination of a face of the slope is steep. SOLUTION: This anchor member 10 is screwed in the ground via a mat body for fixing the mat body laid on the ground, and is composed of a cylindrical body 11 having a peripheral wall opening part 16, and having a space 15 for growing plants inside. The inside space 15 communicates with the outside via the peripheral wall opening part 16. The cylindrical body 11 is formed in the shape of gradually tapering downward. The peripheral wall opening part 16 is opened in the rotational direction so that sediment in the ground enters the inside of the cylindrical body 11 via the peripheral wall opening part 16 when screwed in the ground while rotating the cylindrical body 11 with a shaft extending in the vertical direction of this cylindrical body as the center. The sediment is filled in the inside space 15 of the cylindrical body 11 by being screwed in the ground. Afterwards, the plants are planted inside the cylindrical body 11, and a large number of roots of the plants growing inside the cylindrical body 11 are stretched around in the ground by passing through the peripheral wall opening part 16.

摘要： PROBLEM TO BE SOLVED: To provide an anchor member, which is extremely difficult to slip off even in a soft ground and even in the steep inclination of the face of a slope and can fill the role of greening promotion. SOLUTION: The anchor member 10 is driven into a ground from a lower end section for filing a mat body M such as a water mat, a vegetation mat or the like laid on the ground. The anchor member is composed of a bottomed or bottomless cylindrical body 11 having a space, in which plants grows, on the inside and having fixed length, through-holes 16 capable of passing the cylindrical body 11 to the inside and the outside are bored to a main-body peripheral wall, the cylindrical body 11 is formed so as to be gradually thinned towards a lower end section, and a flange extending in the lateral direction is elongated at the upper end section of the cylindrical body 11 then.

摘要： PROBLEM TO BE SOLVED: To provide a roof greening mat containing plant-growing soil in the mat in a state causing little loss of the soil by running water such as rainwater. SOLUTION: The objective roof greening mat A is provided with spaces capable of holding plant-growing soil in a state causing little loss of the soil by running water such as rainwater. The mat contains a number of continuous filaments 15a made of a thermoplastic resin polymer, irregularly or regularly bending in horizontal or thickness direction while crossing with each other, having a diameter of 0.1-5 mm and extending from one end to the other end of the mat. The mat is composed of a steric net structure 15 formed by welding the numeral continuous filaments 15a at the crossing points and a flexible net member 14 attached to the front or back face of the steric net structure 15. The net member 14 and the steric net structure 15 are integrated together by winding the longitudinal string and/or the lateral string constituting the net member 14 with the continuous filaments 15a.
