Revetment block mat using toe blocks with linear sides
View Patent ↗A mat of revetment blocks formed with interior revetment blocks having interlocking arms and sockets. The mat has opposing sides formed with revetment toe blocks having either an arm or socket that interlocks with a socket or arm of the interior revetment blocks. The toe blocks each have an outer linear edge that forms a linear border of the mat. The toe blocks rest on respective anchor portions that extend into the ground. The mat can be used to form a roadway.
1. A mat made of revetment blocks having a linear border, comprising:
a plurality of interior revetment blocks, each having two engaging arms and two engaging sockets for engaging with respective neighbor revetment blocks;
a first revetment toe block having a socket for engaging with an arm of one said interior block, said first toe block having a linear edge without an arm or a socket on a side opposite the socket of said first toe block;
a second revetment toe block having an arm for engaging with a socket of one said interior block, said second toe block having a linear edge without an arm or a socket on a side opposite the arm of said second toe block; and
said first toe block and said second toe block adapted for laying on a ground surface to be protected from erosion, each said first and second toe blocks having a fixedly attached anchor block that is rectangular in shape and extends orthogonal to and downwardly from the first and second toe blocks, the anchor block of each said first and second toe blocks adapted for being buried in the ground.
2. The mat of revetment blocks of claim 1 , wherein said first toe block is attached to a first said anchor portion with a layer of mortar, and said second toe block is attached to a second said anchor portion with a layer of mortar.
3. The mat of revetment blocks of claim 2 , wherein said first toe block is attached to a first said anchor portion with a layer of mortar before being installed, and said second toe block is attached to a second said anchor portion with a layer of mortar before being installed.
4. A roadway comprised of the mat revetment blocks of claim 1 , further including spaced-apart trenches formed along a path of the roadway, and said anchor blocks buried in the respective trenches.
5. The roadway of claim 4 , wherein the first and second revetment toe blocks form respective linear edges of the roadway.
6. The roadway of claim 5 , wherein the linear edges of the revetment toe blocks are formed with a mold.
7. The mat of revetment blocks of claim 1 , wherein each revetment toe block has a given length that is the same as a length of a respective anchor block attached thereto.
8. A roadway comprised of the mat of revetment blocks of claim 1 , wherein the roadway is designed to carry vehicle traffic.
9. The roadway of claim 8 , wherein said roadway is anchored to the ground by said anchor blocks.
10. The roadway of claim 8 , wherein the arms and sockets of the blocks are articulated sufficiently so that the roadway can be curved.
11. A mat made of revetment blocks having a linear border, comprising:
a plurality of interior revetment blocks, each having two positive interlocking arms and two positive interlocking sockets for engaging with respective neighbor revetment blocks;
a first revetment toe block having a positive interlocking socket for engaging with an interlocking arm of one said interior block, said first toe block having a linear edge without an arm or a socket on a side opposite the interlocking socket of said first toe block;
a second revetment toe block having a positive interlocking arm for engaging with an interlocking socket of one said interior block, said second toe block having a linear edge without an arm or a socket on a side opposite the interlocking arm of said second toe block; and
said first toe block and said second toe block adapted for laying on a ground surface to be protected from erosion, each said first and second toe blocks having a fixedly attached anchor block that is rectangular in shape and extends orthogonal to and downwardly from the first and second toe blocks, the anchor block of each said first and second toe blocks adapted for being buried in the ground.
12. The mat of revetment blocks of claim 11 , wherein said anchor portions are attached to the respective first and second toe blocks with a layer of mortar.
13. A roadway comprised of the mat revetment blocks of claim 11 , further including spaced-apart trenches formed along a path of the roadway, and said anchor blocks buried in the respective trenches.
14. The roadway of claim 13 , wherein the first and second revetment toe blocks form respective linear edges of the roadway.
15. A method of forming a roadway using revetment blocks, comprising:
digging spaced-apart trenches in a path of the roadway;
installing interior revetment blocks along the path of the roadway between the spaced-apart trenches, where the interior revetment blocks each have arms and sockets;
using revetment toe blocks on opposing sides of the interior revetment blocks, where each toe block includes at least one arm or one socket, and where each revetment toe block is associated with an anchor portion; and
installing the anchor portions of the toe blocks in the spaced-apart trenches, and engaging the arm or socket of the respective toe blocks with the respective socket or arm of the neighbor interior revetment blocks.
16. The method of claim 15 , further including using revetment blocks with positive interlocking arms and sockets for the roadway.
17. The method of claim 15 , further including associating the revetment toe blocks with the respective anchor portions by attaching each revetment toe block to a respective anchor portion with a layer of mortar.
