GRID-LOCKED BLOCK PANEL SYSTEM

Related Application This application is a continuation-in-part of co-pending application serial number 08/252,738 for a RETAINING WALL SYSTEM filed by the inventors herein on June 2, 1994.

Backqround of the Invention The present invention relates to an improved concrete block and grid structure and a method and apparatus for constructing panels of interlocked blocks from this structure and embodying such panels in the construction of support surfaces and channel liners for earthen formations and the construction of retaining walls for such formations. In its more specific aspects, the invention concerned with such blocks which have intersecting grooves formed in the undersurface thereof adapted to be engaged over a suspended gridwork which serves to hold assembled blocks in side-by-side relationship.
The prior art teaches concrete blocks formed with grooves which receive rod or clip like members to hold assembled blocks in aligned side-by-side relationship. U.S. Patents 1,959,816 and 1,992,785 are typical of such constructions. The prior art also teaches the provision of T or Z shaped blocks which interlock and are held against separation by clips extending across grooves in the blocks; see for example U.S. Patents 3,998,022 and 4,123,881. It is also known in the prior art to secure stacked face panels for earthen formations in aligned condition through the provision of plates, rods and/or pins extending across the panels and to secure such panels to soil reinforcing gridworks embedded within the PATENT

earthen formation being retained. U.S. Patents 4,324,508 and 4,661,023 exemplify walls of the later type.

Summary of the Invention The present invention is concerned with an integrated concrete block erosion control system wherein the blocks are of an open celled configuration having grooves formed in the body thereof and extending upwardly into the blocks in intersecting relationship to the open cells. The grooves are arranged to complement a wire or polymer gridwork employed therewith so that the blocks may be assembled over the gridwork and held in side-by-side assembled relationship to form a panel comprised of juxtaposed blocks. In the preferred embodiment, at least certain of the blocks are L-shaped so as to interlock when assembled into side-by-side relationship. The gridworks may be held in suspended condition within the blocks by stands, clips and/or grouting. A channel liner formed of panels of the blocks may have dirt fill within the cells to provide for the growth of vegetation. In certain embodiments, barriers may be constructed on the top of a panel used as a channel liner to provide a hydraulic jump. In the preferred embodiment, a free draining material is provided under the panels.
The invention is also concerned with an integrated concrete block wall comprised of concrete blocks having grooves formed in the body thereof and extending upwardly or downwardly therein and relatively narrow gridworks complementally engagable in these grooves, with rods also received within these grooves to hold the gridworks in place and span adjacent blocks. With such an arrangement, the 2! 94745 PATENT

gridworks may be used for soil reinforcement of an earthen formation adjacent the wall. In certain embodiments, the ends of the gridworks received within the grooves of the rods are bent, and the rods are received over or under the bends to secure the gridworks to the block without stressing the transverse wires of the gridworks.
A principal object of the invention is to provide an improved block having intersecting grooves engagable over a gridwork to enable a plurality of such blocks to be assembled over the gridwork in side-by-side relationship and held together in a panel configuration by the gridwork.
Another object is to provide a panel constructed of such blocks which may be lifted into place as a unit.
Still another object is to provide a panel constructed of such blocks which may be used as a liner within an earthen channel for erosion control.
Another object is to provide a panel of such blocks which may be used as a support surface over an earthen formation and functions to distribute concentrated loads applied thereto over an extended area of the formation.
Yet another object is to provide an assembly of such blocks which may be used both for erosion control and in the construction of a retaining wall for an earthen formation.
Still another object of the invention is to provide a panel constructed of such blocks wherein the gridwork is held in suspended condition within the blocks by hangers extending over the blocks and into engagement with the gridwork.
A further object of the invention is to provide a panel constructed of such blocks wherein the blocks 2 1 9 ~ 7 45 PATENT

have open cells and the gridwork over which the blocks are assembled intersect these cells.
Yet another object related to the later object is to provide a panel constructed of such blocks wherein certain of the cells may be grouted to anchor the gridwork within the blocks.
Still a further object of the invention is to provide a wall constructed of concrete blocks having grooves therein for the complemental receipt of gridworks which may be used for soil reinforcement and rods received within the grooves to hold the gridworks in place and span adjacent blocks.
These and other objects will become more apparent when viewed in light of the accompanying drawings and the following description.

21 9~745 PATENT

Descri~tion of the Preferred Embodiment Referring now to Figure 1, an L shaped block B
constructed according to the present invention is shown therein assembled over a suspended gridwork G.
The block G is fabricated of a cementious material such as concrete and is formed with open cells C
extending therethrough from top to bottom. The respective cells are separated from one another by webs W. Each cell of the L-shaped block B is of a generally rectangular cross-section, with one or more walls provided by the webs W and the remaining walls 10 being disposed on the outside of the block.
Grooves 12 extend upwardly through the block in intersecting relationship to the cells C. The grooves 12 have a height equal to approximately one-half the depth of the block.
The gridwork G may be of a welded wire construction, or a polymeric "geogrid" construction.
In either event, it is comprised of intersecting elements 14 proportioned and spaced for receipt in the intersecting grooves 14, as may be seen from Figures 1 and 2. There it will also be seen that the intersecting elements 14 are disposed at right angles relative to one another and define a square space therebetween.
Figures 1 and 2 illustrate that the gridwork G
is suspended so as to be at the top of the grooves 12. During assembly of the blocks over the gridwork, such suspension may be temporarily provided by supporting the gridwork on stands 16, as depicted in Figure 3. As thereshown, the stands are supported on a support surface 18 at an elevation approximately equal to the height of the grooves 12. Figure 3 shows the blocks B engaged over the gridwork and supported on the surface 18. Figure 3 also ~I q4745 PATENT
_ g_ illustrates a wire connector 20 extending over a pair of juxtaposed blocks B. The connector 20 serves as a hanger for the gridwork and engages under the intersecting wires of the gridwork to either side of the blocks over which the connector extends. A first hook 22 (see Fig. 5) is formed on the connector for engagement over the wire 14 extending lengthwise as viewed in Figure 3. A second hook 24 formed on the end of the connector 20 opposite the hook 22 engages over the wire 14 extending normal to the page, as viewed in Figure 3. In applying the hanger, the hook 22 would first be engaged and the end of the connector 20 formed with the hook 24 would be bent downwardly and engaged under the element 14 therefor.
It should be appreciated that the connector 20 is engaged over the blocks and under the gridwork after the blocks are in place on the suspended gridwork, as shown in Figure 3. Once the connector is so placed and the gridwork is suspended thereby, support of the gridwork is no longer dependent upon the stands 16. Figure 1 also shows a gridwork G
supported by a connector 20. Figure 2 shows the cells of the block B filled with cement grout 26 to hold the gridwork in place. The grout serves as a concrete connection between the gridwork and the block and may be used in place of or in addition to the connectors 20.
Figure 6 shows the L-shaped block B inverted with the grooves facing upwardly. As thereshown, it will be seen that the outside corners of the block are formed with chamfers 28 and that the outside surfaces of the block are formed with V-shaped grooves 30 between the cells C. Also thereshown it will be seen that a generally rectangular groove 32 is formed in the outside surface of the block between - 21 q~7~5 PATENT

the legs of the block which make up the L-shape. The chamfers 28 and the grooves 30 and 32 facilitate nesting of the blocks into an assembled panel as shown in Figure 7 and provide generally rectangular passages which extend through the panel.
As shown in Figure 7, only L-shaped four cell blocks of the type shown in Figures 1-6 have been used. The block shown in exploded perspective in Figure 7 is in the process of being placed. It will be appreciated that the resulting panel cannot completely fill the rectangular configuration of the gridwork G shown in Figure 7. This results because the four cell L-shaped blocks, by themselves, are incapable of being assembled into a composite shape corresponding to the rectangular shape of the gridwork. To provide such a composite shape, ideally a combination of blocks having the shape seen in Figures 8-12 need to be provided. The block B of Figure 8 is the same L-shaped block which has been described previously. The block Bl of Figure 9 is a L-shaped block comprised of three cells only. The block B2 of Figure 10 is of a rectilinear shape comprising three cells. The block B3 of Figure 11 is a rectilinear block comprised of two cells and the block B4 of Figure 12 is comprised of only one cell.
The different block configurations Bl, B2, B3 and B4 may be formed by breaking a block B along the cutlines 34, 35, and 36 shown in Figure 8. The grooves 30 and 32 facilitate breaking along the cutlines. As an alternative, the blocks B1, B2, B3 and B4 can be initially molded in their final configuration.
Figure 13 shows blocks B, B1, B2, B3 and B4 assembled into a full rectangular panel over a gridwork G. As thereshown, the corner cells and the PATENT

cells midway of each side of the panel and in the center of the panel are filled with cement grout 26.
The resulting panel is thus locked to the gridwork and the blocks within the panel interlock with one another.
Figure 14 shows block panels constructed according to the present invention assembled into place to form an erosion resistant liner for a channel within an earthen formation. The panels, designated P, may be constructed according to Eigure 13. The earthen formation is designated E and is shown as having a generally horizontal lower surface 36 and a sloped side surface 38. It should be appreciated that Figure 14 depicts only one half of the channel and that the other half would extend to the left of what is shown in Figure 14 and be a mirror image thereof. The earthen channel is covered with filter fabric 40 having drain rock 42 disposed thereover. The drain rock serves to support the panels P in spaced relationship to the earthen formation.
Figure 15 shows a panel P supported above a generally horizontal portion of an earthen formation E and separated from the formation by filter fabric 40 and drain rock 42. As thereshown, the panel P is supported on the drain rock. A short stud wall S is fixed to and extends upwardly from the panel P. The stud wall is held in place by angle shaped reinforcing bars 44 extending through the blocks of the panel P and upwardly therefrom. The stud wall is comprised of blocks corresponding to any of the blocks B, Bl, B2, B3 or B4 stacked over the bars 44 so that the bars extend through the cells of the blocks.
Within each level of blocks of the stud wall, a short gridwork G1 secures the blocks together. Ideally, PATENT

grouting is placed within the cells of the blocks of the stud wall to provide an integral structure. The stud wall may be for any desired purpose. For example where the panels P are a part of a channel liner as shown in Figure 14, the stud wall may serve as a hydraulic jump to break-up the flow of water through the channel.
Figure 16 shows an earthen formation having a base portion 46 and an upstanding generally inclined portion 48 terminating in a top surface 50. As thereshown, the base portion P is covered with a panel P and a series of blocks B are stacked upon the later panel in inverted orientation in front of the upstanding portion 48. Each level of the inverted blocks has a gridwork G engaged in the grooves thereof and extending toward the upstanding portion 48. Rods 51 may also extend through the grooves of the inverted blocksO Filter fabric 40 is disposed over the top surface 50 and the surfaces of the base portion 46 and upstanding porion 48. Drain rock 42 is disposed between the base portion 46 and the panel P thereover, as well as between the upstanding portion 48 and the inverted blocks B. An upper panel P is disposed at the top of the inverted blocks B and extends over and in spaced relationship to the top surface 50. Drain rock is also disposed between the top surface 50 and the upper panel P.
The retaining wall arrangement of Figure 16 acts much like a gravity wall, except that the gridworks G
secured to the inverted blocks B serve to reinforce the drain rock and to help secure the inverted blocks in place. Although not illustrated, it is possible that the gridwork G secured to the inverted blocks B
might extend into the earthen formation to serve to ~1 94745 PATENT

reinforce the formation and further secure the inverted blocks in place.
Figure 17 shows how a panel P may be lifted and placed as a unit. As thereshown, hoisting cables 52 are secured to the gridwork G at spaced locations and connected to a lifting line 54 which may be secured to a crane or the like. Although only two cables 52 are shown, it should be appreciated that a plurality of such cables would be provided, preferably in a triangulated pattern, so that the panel would remain in a stable condition and not swing around its connections to the panel during the lifting process.
With the lifting arrangement shown in Figure 16, a preassembled panel of blocks may be hoisted into an elevated condition and then moved to the site where it is to be placed and lowered into position.
Figure 18 depicts a panel P supported above the surface of an earthen formation E on drain rocks 42.
Filter fabric 40 is disposed between the drain rocks and the formation. A concentrated load, as might be provided by a wheel W, is shown being applied to the surface of the panel. The dotted lines 55 diverging through the panel and the drain rock depict how the concentrated load is transferred to the earthen formation over an expanded area. Such divergent application of the load is ideal, in that it minimizes the likelihood of depression of the panel and the rock therebeneath as the result of the concentrated load.
Two blocks B are shown assembled in end-to-end relationship in Figure 19 to provide a wall wherein the grooves of the blocks extend upwardly and the short legs of their L-configuration extend to the back of the wall. Narrow gridworks G2 having longitudinal elements 56 spaced from one another by a ~ 94745 PATENT

distance equal to the space between adjacent grooves in the sides of the block are connected by cross-elements 58. The arrow lines in Figure 19 depict how the gridworks G2 are engaged with the grooves within the blocks. Rods or bars 60 and 62 are disposed above the cross-elements 58 received within the block and proportioned for receipt within the grooves 12.
Figure 20 shows a wall constructed according to Figure 19 in fully assembled condition with the gridworks G2 and bars 60 and 62 in place. As there shown, distal cross-elements 58 of the gridworks are received within the grooves of the blocks and the bars 60 and 62 are disposed over the gridworks so as to be immediately behind these cross-elements. The latter arrangement can also be seen from Figure 21 wherein the connection between a gridwork G2 and block B is illustrated.
Figure 20 also shows that the bars 60 and 62 span adjacent blocks to hold the blocks in transverse alignment. The blocks may be further locked together by disposing grout within the cells C around the gridworks and the bars. It should also be appreciated that positioning of the bars 60 and 62 behind the distal cross-elements 58 distributes the load applied to the cross wires along their length and resists pull-out forces which may be applied to the gridworks.
The assembled wall and gridwork structure of Figures 20 to 21 is ideally suited for use in constructing retaining walls for earthen formations wherein the gridworks are embedded within backfill at the face of the formation. Use of the relatively narrow soil reinforcing mats provided by the gridworks G2 has the advantage that it decreases the stiffness of the earthen mass and accommodates - 2 1 q4 745 PATENT

settlement of the earthen formation with a minimum of stress to the mats and the wall face provided by the blocks.
The assembly shown in Figure 22 is essentially the same as that shown in Figure 19, except that the gridworks, designated G3, have bent-up portions 64 and the distal cross-elements 58 are secured across these portions. In the assembled position, as shown in Figure 23, the bent-up portions 64 extend upwardly relative to the grooves 12 and the bars 60 are disposed within the grooves behind the bent-up portions. As the result of the latter arrangement, the bars 60 resist pull-out of the gridworks G2 from the blocks, without being dependent upon the strength of the connection between the distal cross-elements 58 and the longitudinal elements 56.
Figures 24 and 25 show a block wall and gridwork combination corresponding to that of Figures 19 to 21, except that the blocks are inverted relative to what is shown in Figure 19 so that the grooves 12 therein extend downwardly. In Figure 25, it will be seen that in the assembled condition the gridworks G2 are at the top of the grooves 12 and held in place by a wire connector or hanger 2Oa corresponding in construction to the hanger 20, except that it is proportioned to engage over a single wall thickness of the block B and under and around a bar 60 and cross-element 58.
Figure 26 shows a wall constructed according to that of Eigures 22 and 23, except that the blocks B
are inverted so that the grooves 12 therein face downwardly. As there shown, the gridwork G3 is held at the top of the groove 12 by a wire connector 2Ob corresponding generally to the connector 20, except that it is proportioned to engage over a single wall 2 l 9 4745 PATENT

thickness of the block B and under and around the rod 60. As shown in Figure 26, the bent portion 64 of the gridwork G3 extends downwardly.
Figure 27 shows a wall construction corresponding to that of Figure 26 except that the gridwork G3 is disposed so that the bent portion 64 extends upwardly into the groove 12 of the block and the bar 60 rests on top of the longitudinal elements 56 of the gridwork. As assembled in Figure 27, the bar 60 rests on the longitudinal element 56 and no connector is required to suspend the bar. Suitable stands, such as those shown in Figure 3, could be used to support the gridwork G3 in elevated condition during the course of construction of the Figure 27 wall. Like the walls of Figures 22-23 and 26, positioning of the bar 60 at the bend of bent-up portion 64 enables tension forces applied to the longitudinal element 56 to be transmitted to the bent-up portion 64 without loading the connection between the distal cross-element 58 received within the groove 12.
Figure 28 shows an earthen formation similar to that of Figure 16 having a base portion 46 and an upstanding, generally inclined portion 48. The base portion is covered with a panel P and a retaining wall comprised of blocks assembled as shown in Figures 19 to 21 and stacked upon one another in slightly staggered relationship is supported on the panel. Gridworks G2 are secured to the stacked blocks in the manner shown in Figures 20 and 21 and extend through drain rock 42 and into compacted backfill soil 66. The extension of the gridworks into the backfill soil serves to reinforce the soil and secure the face wall comprised of the stacked blocks against displacement. The cut face of the 2'. 94745 -PATENT

natural soil formations shown in Figure 28 is depicted by the numeral 68.

Conclusion From the foregoing description, it is believed apparent that the present invention enables the attainment of the objects initially set forth herein.
In particular, it provides an integrated block construction wherein the blocks are interlocked with one another both through their configuration and through the gridwork engaged therewith. It also provides such a construction which may be lifted into place as a panel and is ideally suited for controlling erosion in earthen channels and for assembly into various types of erosion control systems and retaining structures for earthen formations. It also provides a structure wherein concentrated loads applied to a panel constructed from the integrated blocks are supported over a diverse area to provide increased support.
While preferred embodiments of the invention have been illustrated and described, it should be understood that the invention is not intended to be limited to the specifics of these embodiments, but rather is defined by the accompanying claims.
