Abstract
Abstract An erosion control system that uses massive hollow reinforced concrete blocks that can contain bulky fill material such as sand, mud, shell or concrete rip rap. The blocks can be arranged in desired geometric patterns at coastal areas subject to erosion control.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
106 words
A method of coastal erosion control comprising the steps of: a. transporting a plurality of massive and transportable hollow concretious blocks of concrete reinforced with steel to a coastal site where erosion is to be controlled; b. arranging the massive blocks in an array that extends along the erosion site so that the blocks can dissipate wave action; c. filling the hollow blocks with loose fill material until each of the blocks has a weight of at least twenty five (25) tons; and d. sealing each block after the loose fill material is added so that wave action cannot scatter the fill material during heavy seas.
Claim 2
Independent Claim
106 words
A method of coastal erosion control comprising the steps of: a. transporting a plurality of massive and transportable hollow concretious blocks of concrete reinforced with steel to a coastal site where erosion is to be controlled; b. arranging the massive blocks in an array that extends along the erosion site so that the blocks can dissipate wave action; c. filling the hollow blocks with loose fill material until each of the blocks has a weight of at least twenty five (25) tons; and d. sealing each block after the loose fill material is added so that wave action cannot scatter the fill material during heavy seas.
Claim 3
Dependent Claim
28 words
The method of claim 1 wherein each block has an upper and lower flattened surface area so that a plurality of blocks can be stacked upon each other.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein in step "b" the blocks are spaced apart so that water can flow between the blocks.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein the blocks are rectangular prisms.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein the blocks have minimal dimensions of fourteen feed (14') long, eight feet (8') high, and six feet (6') wide.
Claim 7
Dependent Claim
16 words
The method of claim 1 wherein in step "c", the fill material comprises blocks of aggregate.
Claim 8
Dependent Claim
11 words
The method of claim 6 wherein the fill is concrete rip-rap.
Claim 9
Independent Claim
116 words
An apparatus for controlling coastal erosion comprising: a. a plurality of massive, hollow, transportable, concrete blocks reinforced with steel; b. lifting eye means spaced around the periphery of each block; c. the blocks including four continuous connected side walls and a bottom wall defining a block interior; d. means for closing the top of the block to form a sealed interior after fill material has been added to the block interior; and e. the blocks being arranged in an array to form a geometric pattern of blocks along a coastal zone where erosion is to be controlled, and in a position spaced from the shoreline so that wave action is dissipated before it reaches the shoreline.
Claim 10
Independent Claim
116 words
An apparatus for controlling coastal erosion comprising: a. a plurality of massive, hollow, transportable, concrete blocks reinforced with steel; b. lifting eye means spaced around the periphery of each block; c. the blocks including four continuous connected side walls and a bottom wall defining a block interior; d. means for closing the top of the block to form a sealed interior after fill material has been added to the block interior; and e. the blocks being arranged in an array to form a geometric pattern of blocks along a coastal zone where erosion is to be controlled, and in a position spaced from the shoreline so that wave action is dissipated before it reaches the shoreline.
Claim 11
Dependent Claim
28 words
The apparatus of claim 8 wherein each block has an upper and lower flattened surface area so that a plurality of blocks can be stacked upon each other.
Claim 12
Dependent Claim
19 words
The apparatus of claim 8 wherein the blocks are spaced apart so that water can flow between the blocks.
Claim 13
Dependent Claim
11 words
The apparatus of claim 8 wherein the blocks are rectangular prisms.
Claim 14
Dependent Claim
25 words
The apparatus of claim 8 wherein the blocks have minimal dimensions of fourteen feet (14') long, eight feet (8') high, and six feet (6') wide.
Claim 15
Dependent Claim
13 words
The apparatus of claim 8 wherein the fill material comprises blocks of aggregate.
Claim 16
Dependent Claim
11 words
The apparatus of claim 13 wherein the fill is concrete rip-rap.
Claim 17
Independent Claim
70 words
An apparatus for controlling coastal erosion comprising: (a) a massive, hollow, transportable, concrete block reinforced with steel; (b) lifting eye means spaced around the periphery of the block; (c) the block including four continuous connected side walls and a bottom wall defining a block interior; and (d) means for closing the top of the block to form a sealed interior after fill material has been added to the block interior.
