Abstract
A retaining wall structure built of sand/soil bags has interconnecting members placed between adjacent courses of bags to attach the adjacent courses to one another. The interconnecting members are plates having projections on both sides which penetrate into the sand/soil bags of the adjacent courses. Sheets of geogrid extend from between courses of sand/soil bags into the fill retained by the sand/soil bags. Projections on the interconnecting members penetrate through holes in the geogrid sheet, anchoring the wall face to the reinforced soil structure.
Description
RETAINING WALL SYSTEM WITH
INTERLOCKED SANDBAGS
Technical Field The invention pertains to retaining walls and to methods of constructing retaining walls. In particular, it pertains to retaining walls built of sand/soil bags wherein the bags in adjacent courses are connected together.
Back r Retaining walls are used in a wide variety of civil engin-eering and landscaping applications, for example to support slopes and embankments for highways and railways, support noise barriers, etc.
Retaining walls are commonly made having a supporting face structure made of interconnecting blocks with soil or other fill placed and compacted in back of the face structure, and with sheets of geogrid laid in the fill at various levels, extending back from the face of the wall. The geogrid sheets, which stabilize the backfill, are often attached to the interlocking blocks. It is known to build retaining walls of sandbags instead of interlocking blocks to hold the backfill.
In the prior art, sandbags in retaining walls are not attached to each other, relying essentially on their mass to stabilize the wall. This limits the steepness and the height of retaining walls that can be build with sandbags. Sandbag retaining walls, in the prior art, are normally temporary, rather than permanent, structures.
Summary of Invention The invention provides a permanent retaining wall struc-ture in which the sand/soil bags used to make the face of the structure are attached to sand/soil bags in adjacent courses, and to geogrid sheets. The attachment is done by means of a plate having spikes on both sides thereof which penetrate the bags in adjacent courses, and which also penetrate the holes in the geogrid sheets, stabilizing the retaining wall structure.
In this specification, "sand/soil bag" means a bag filled with any suitable fill material, including sand, soil, mixtures thereof and including fill mixed with seeds for grass or other plants.
The invention provides a retaining wall structure compris-ing a first plurality of sand/soil bags positioned adjacent to one another forming a first, horizontally-extending course; a second plurality of sand/soil bags positioned adjacent to one another above the first course forming a second course; interconnecting members placed between the first and second courses attaching them together. The interconnecting members comprise a plate having an upper side and a lower side, a first set of projections on the lower side and a second set of projec-tions on the upper side, the projections being capable of penetrating a sand/soil bag. The interconnecting members are positioned between the sand/soil bags of the first and second courses so that the first set of projections penetrates a bag in the lower course and the second set of projections penetrates a bag in the upper course.
The retaining wall structure can optionally comprise a sheet of geogrid extending from between the first and second courses into backfill behind the retaining wall. The geogrid sheet is positioned so that projections of the interconnecting member penetrate through holes in the sheet.
The invention also provides a method of constructing a retaining wall structure having a plurality of courses of sand/soil bags.
The method comprises the steps of placing a first plurality of sand/soil bags adjacent to one another to form a first, horizontally-extending course; placing interconnecting members on the first course, the interconnecting members having a first set of projections on their lower side and a second set of projections on their upper side, such that the projections in the first set penetrate sand/soil bags in the first course of sand/soil bags; placing a plurality of sand/soil bags adjacent to one another to form a second course above the first course, such that the projections of the second set penetrate bags of the second course. The method of constructing a retaining wall can include the step of placing a sheet of geogrid extending from between the courses of sand/soil bags into the backfill, with projections of the interconnect-ing member penetrating through holes in the geogrid to anchor it in place.

Description Referring to Fig. 1, retaining wall structure 10, con-structed on ground 12, has a supporting face comprising a plurality of horizontally-laid courses of sand/soil bags 14, the courses being arranged vertically in a wall structure. The face of the wall may be sloped, rather than vertical, if so preferred for a particular application.
The bags 14 are preferably made of a geotextile material which is durable and of a weave which permits water to flow in and through the bag, and seeding to grow out, while retaining fine soil particles within the bags. Backfill 16 is compacted behind and supported by sand/soil bags 14. Geogrid sheets 18 extend horizontally back into the backfill from between courses of sand/soil bags 14, affixed thereto as described hereunder. Interconnecting members 26 are placed between the adjacent courses of sand/soil bags 14.
Referring to Figs. 2 and 3, interconnecting member 26 comprises a plate 22, generally rectangular and planar, with a plurality of projections 24 extending vertically from both sides of the plate 22.
Projections 24 are sufficiently strong and pointed to penetrate sand/soil bags 14. Interconnecting member 26 is preferably made of plastic or aluminum or other non-corrosive material.
Referring to Figs. 4 and 5, interconnecting members 26 are used in the construction of a retaining wall structure 10 by placing them on top of sand/soil bags 14 in a course so that projections 24 on the lower side penetrate the bags. A second course of bags is placed on top of the first course and of interconnecting members 26. The projections on the upper side of member 26 penetrate the bags in the second course, and the weight of those sand/soil bags presses the interconnecting members so that the projections on their lower side fully penetrate the bags in the first course.
The interconnecting members 26 are also used to anchor geogrid sheets to the sandbags. Geogrid sheets 18 are known and commercially available plastic mesh products commonly used for soil reinforcement. Referring to Fig. 5, geogrid sheet 18 has a plurality of holes 28 therein. The sheet 18 is affixed to the face of the wall by placing the edge of the sheet over interconnecting members 26 atop a course of sandbags 14 so that the projections 24 on the upper side of the interconnecting member and adjacent its back edge penetrate through holes 28 in the geogrid. When the next upper course of bags 14 is put on top, projections 24 on the upper side of the interconnect-ing member, extending through the geogrid sheet, penetrate into the underside of the bags in said upper course.
Instead of being placed over an interconnecting member 26, the geogrid sheet can be placed directly on top of a course of sand/soil bags and the interconnecting members placed over it, with the projections 24 on the lower side of the member 26 penetrating down through holes 28 in the geogrid sheet and into the bags. In other words, the geogrid can be placed under the interconnecting member as well as over it.
Geogrid sheets are installed at selected levels during the construction of the wall, for example on top of every third course of bags, or as required for a particular application.
Fig. 6 illustrates the steps in a preferred method of con-structing a retaining wall structure according to the invention. Refer-ring to Fig. 6(a), a trough 30 is dug in ground 12. A first course of sand/soil bags 14 is laid in trough 30 (Fig. 6(b)). A row of intercon-necting members 26 is placed on top of bags 14 in the first course (Fig. 6(c)). Next, further courses of bags 14 are laid, and backfill 16 is placed and compacted in back of the sand/soil bags (Fig. 6(d)).
Then, a row of interconnecting members 26 is placed along the upper-most course of bags 14 and a sheet of geogrid 18 is placed on it, extending back along the surface of the backfill 16 (Fig. 6(e)). The construction of the wall is continued in the same manner, until a retaining wall of the required height is completed, as shown in Fig. 1.
According to one embodiment of the invention, bags 14 include seeds of grass or other ground covers mixed in their fill.
After the retaining wall is built, the bags are watered, naturally or artificially, and the ground cover plants grow out of the bags, provid-ing a green foliage face on the retaining wall.
According to another embodiment of the invention, the bags do not include seeds but are instead made in shapes which, in a completed wall, will form an attractive wall face. For example, the face side of the bags can be rectangular, square or hexagonal, to permit the construction of a wall face with any of various interlocking patterns.
Figs. 7-10 illustrate alternative embodiments of the inter-connecting member. In these embodiments, the interconnecting member has different shapes to permit optimal interlocking of bags of various shapes and in various arrangements. Rounded or shapeless bags may have gaps between adjacent bags in a course such that an interconnecting member extending across such bags is not fully sup-ported across such gap by the lower bags. In such cases it is prefer-able to use an interconnecting member with a cut-out in the unsup-ported area, so that an upper bag does not press down on an unsup-ported part of the interconnecting member. In Fig. 7, interconnecting member 126 comprises plate 122 with projections 24 on both sides thereof. The plate 122 is generally C-shaped with a space or cut-out 123 between the arms of the C. The interconnecting member 126 is positioned between courses of sand/soil bags such that the space 123 is above the gap between adjacent bags in the lower course. A portion of the bag in the upper course extends through the space 123 and rests directly on the lower bags. A similar design is shown in Fig. 10, in which interconnecting member 226, having projections 24 on both sides thereof, is in the form of a rectangular frame with a cut-out 52 in the middle thereof. As with the embodiment of Fig. 7, this inter-connecting member permits part of the upper bag to rest directly on the lower bags while still interlocking bags in adjacent courses together.
Two further alternate configurations are shown in Fig. 8 and Fig. 9. In Fig. 8, interconnecting member 326 is hemi-cylindrical in shape. In Fig. 9, interconnecting member 426 is L-shaped. Both these forms of interconnecting members are adapted for use in inter-locking sand/soil bags of the appropriate shapes. It will be apparent that the interconnecting member can be configured as required to interlock sand/soil bags of any desired shape.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. For example, the interconnecting member can be made flexible to conform to the shape of the sandbags. The projec-dons on it can be barbed, to enhance their attachment to the sandbags, and they can project at angles other than the vertical from the plate.
Accordingly, the scope of the invention is to be construed in accor-dance with the substance defined by the following claims.

Description Referring to Fig. 1, retaining wall structure 10, con-structed on ground 12, has a supporting face comprising a plurality of horizontally-laid courses of sand/soil bags 14, the courses being arranged vertically in a wall structure. The face of the wall may be sloped, rather than vertical, if so preferred for a particular application.
The bags 14 are preferably made of a geotextile material which is durable and of a weave which permits water to flow in and through the bag, and seeding to grow out, while retaining fine soil particles within the bags. Backfill 16 is compacted behind and supported by sand/soil bags 14. Geogrid sheets 18 extend horizontally back into the backfill from between courses of sand/soil bags 14, affixed thereto as described hereunder. Interconnecting members 26 are placed between the adjacent courses of sand/soil bags 14.
Referring to Figs. 2 and 3, interconnecting member 26 comprises a plate 22, generally rectangular and planar, with a plurality of projections 24 extending vertically from both sides of the plate 22.
Projections 24 are sufficiently strong and pointed to penetrate sand/soil bags 14. Interconnecting member 26 is preferably made of plastic or aluminum or other non-corrosive material.
Referring to Figs. 4 and 5, interconnecting members 26 are used in the construction of a retaining wall structure 10 by placing them on top of sand/soil bags 14 in a course so that projections 24 on the lower side penetrate the bags. A second course of bags is placed on top of the first course and of interconnecting members 26. The projections on the upper side of member 26 penetrate the bags in the second course, and the weight of those sand/soil bags presses the interconnecting members so that the projections on their lower side fully penetrate the bags in the first course.
The interconnecting members 26 are also used to anchor geogrid sheets to the sandbags. Geogrid sheets 18 are known and commercially available plastic mesh products commonly used for soil reinforcement. Referring to Fig. 5, geogrid sheet 18 has a plurality of holes 28 therein. The sheet 18 is affixed to the face of the wall by placing the edge of the sheet over interconnecting members 26 atop a course of sandbags 14 so that the projections 24 on the upper side of the interconnecting member and adjacent its back edge penetrate through holes 28 in the geogrid. When the next upper course of bags 14 is put on top, projections 24 on the upper side of the interconnect-ing member, extending through the geogrid sheet, penetrate into the underside of the bags in said upper course.
Instead of being placed over an interconnecting member 26, the geogrid sheet can be placed directly on top of a course of sand/soil bags and the interconnecting members placed over it, with the projections 24 on the lower side of the member 26 penetrating down through holes 28 in the geogrid sheet and into the bags. In other words, the geogrid can be placed under the interconnecting member as well as over it.
Geogrid sheets are installed at selected levels during the construction of the wall, for example on top of every third course of bags, or as required for a particular application.
Fig. 6 illustrates the steps in a preferred method of con-structing a retaining wall structure according to the invention. Refer-ring to Fig. 6(a), a trough 30 is dug in ground 12. A first course of sand/soil bags 14 is laid in trough 30 (Fig. 6(b)). A row of intercon-necting members 26 is placed on top of bags 14 in the first course (Fig. 6(c)). Next, further courses of bags 14 are laid, and backfill 16 is placed and compacted in back of the sand/soil bags (Fig. 6(d)).
Then, a row of interconnecting members 26 is placed along the upper-most course of bags 14 and a sheet of geogrid 18 is placed on it, extending back along the surface of the backfill 16 (Fig. 6(e)). The construction of the wall is continued in the same manner, until a retaining wall of the required height is completed, as shown in Fig. 1.
According to one embodiment of the invention, bags 14 include seeds of grass or other ground covers mixed in their fill.
After the retaining wall is built, the bags are watered, naturally or artificially, and the ground cover plants grow out of the bags, provid-ing a green foliage face on the retaining wall.
According to another embodiment of the invention, the bags do not include seeds but are instead made in shapes which, in a completed wall, will form an attractive wall face. For example, the face side of the bags can be rectangular, square or hexagonal, to permit the construction of a wall face with any of various interlocking patterns.
Figs. 7-10 illustrate alternative embodiments of the inter-connecting member. In these embodiments, the interconnecting member has different shapes to permit optimal interlocking of bags of various shapes and in various arrangements. Rounded or shapeless bags may have gaps between adjacent bags in a course such that an interconnecting member extending across such bags is not fully sup-ported across such gap by the lower bags. In such cases it is prefer-able to use an interconnecting member with a cut-out in the unsup-ported area, so that an upper bag does not press down on an unsup-ported part of the interconnecting member. In Fig. 7, interconnecting member 126 comprises plate 122 with projections 24 on both sides thereof. The plate 122 is generally C-shaped with a space or cut-out 123 between the arms of the C. The interconnecting member 126 is positioned between courses of sand/soil bags such that the space 123 is above the gap between adjacent bags in the lower course. A portion of the bag in the upper course extends through the space 123 and rests directly on the lower bags. A similar design is shown in Fig. 10, in which interconnecting member 226, having projections 24 on both sides thereof, is in the form of a rectangular frame with a cut-out 52 in the middle thereof. As with the embodiment of Fig. 7, this inter-connecting member permits part of the upper bag to rest directly on the lower bags while still interlocking bags in adjacent courses together.
Two further alternate configurations are shown in Fig. 8 and Fig. 9. In Fig. 8, interconnecting member 326 is hemi-cylindrical in shape. In Fig. 9, interconnecting member 426 is L-shaped. Both these forms of interconnecting members are adapted for use in inter-locking sand/soil bags of the appropriate shapes. It will be apparent that the interconnecting member can be configured as required to interlock sand/soil bags of any desired shape.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. For example, the interconnecting member can be made flexible to conform to the shape of the sandbags. The projec-dons on it can be barbed, to enhance their attachment to the sandbags, and they can project at angles other than the vertical from the plate.
Accordingly, the scope of the invention is to be construed in accor-dance with the substance defined by the following claims.
