Benefits of technology

[0004] The invention is based on the principle that it is possible to grow vegetation on a sandbag wall by using sandbags that are not completely filled with soil, but have soil as a fill material at one end of the bag, while the rest of the bag is filled with other, cheaper, fill materials.

Problems solved by technology

Soil of a quality sufficient to facilitate the growth of an adequate vegetation cover, mixed with seeds, is a relatively expensive fill material for use in sandbags.

Embodiment Construction

[0012] In the following description and drawings, corresponding and like parts are referred to by the same reference characters.

[0013] With reference to FIG. 1 of the drawings, sandbag 10 comprises a bag 12 filled with fill material 24. The bag has a wall 14, a closed bottom end 16 and a top end 18, which has opening 20 that is closed by means of a tie 22. The sandbag is accordingly sealed to retain the fill material within its interior. The bag 12 is preferably made of geotextile and is formed of a single piece thereof by sewing along the bottom and a longitudinal side of the bag.

[0014] Sandbag 10 has a length L between its opposed ends 16, 18, and a width W, and a depth, the length being greater than the width.

[0015] Fill material 24 comprises soil 24A mixed with plant seeds, which is put at the bottom end of the bag, and a second fill material 24B, which may be sand, gravel, etc., depending on the particular application and the availability of such fill materials. If desired, ...

Abstract

The sandbag for use in constructing retaining walls having a vegetation-covered wall face. The sandbag contains soil mixed with seeds as a first fill material at one end of the bag, and the remainder of the bag is filled with a cheaper fill material such as sand or gravel. The sandbags are arranged in a sandbag wall such that the ends of the bags having the soil and seed mixture forms at least part of the outer face of the wall.

Description

TECHNICAL FIELD [0001] The invention pertains to sandbag wall systems for use in erosion control, flood protection, coastal protection, slope stabilization and similar applications, and to improved bags and walls. BACKGROUND OF THE INVENTION [0002] In the art of erosion control, flood protection, coastal protection, slope stabilization and the like, it is known to build strong and effective retaining walls made with sandbags, preferably using interconnecting members to connect the bags together and stabilize the wall. See, for example, International patent publication WO 00 / 61880 (Kim) dated Oct. 19, 2000. It is often desirable to grow vegetation on the face of a sandbag retaining wall, both for aesthetic reasons and to provide additional protection to the wall face. This can be done by using soil mixed with grass seed or other plant seeds as a fill material. The bags are made of geotextile or other material which permits plants to grow out through the bag walls. As the seeds in the...
