Abstract
Abstract A canal bank retaining wall means and method of making same comprising, an elongate wall poured in place on an earthen canal bank immediately after digging said canal, said retaining wall having expansion joint means therein at spaced intervals along the length thereof for enabling expansion and contraction of said wall upon temperature changes in the surrounding environment. If desired, removable sections may be provided in said retaining wall so that said sections may be removed after the canal is constructed in order that a boat slip or a dock the like may be economically built in said retaining wall. Also, the surface of the retaining wall exposed to the water in said canal may be roughened to provide an ecologically better environment for marine life and other organisms, if desired.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
67 words
A reinforced concrete, inclined canal bank retaining wall having a top and a bottom and poured directly on an inclined earthen canal bank, a plurality of spaced apart expansion joint strips in said retaining wall extending from the top thereof to adjacent the water line in the canal, sAid concrete being continuous and uninterrupted below the expansion joint strips, thus resulting in a strong retaining wall structure.
Claim 2
Dependent Claim
67 words
A reinforced concrete, inclined canal bank retaining wall having a top and a bottom and poured directly on an inclined earthen canal bank, a plurality of spaced apart expansion joint strips in said retaining wall extending from the top thereof to adjacent the water line in the canal, sAid concrete being continuous and uninterrupted below the expansion joint strips, thus resulting in a strong retaining wall structure.
Claim 3
Dependent Claim
123 words
A concrete canal bank retaining wall as in claim 1, wherein said concrete retaining wall has a roughened surface at least below the water line of said canal, said roughened surface comprising a separate layer of stone aggregate on top of the concrete, said stones preferably comprising native rock from local sources, at least some of the stones of the aggregate embedded at least partially in said concrete retaining wall, thereby creating an anchored rock canal bank lining which markedly increases the contact surface of said canal bank retaining wall and thus creates a multitude of ecological niches wherein marine and/or related organisms and the like can attach, live, escape predators, and otherwise exist, thereby greatly improving the marine environment of said canal.
Claim 4
Dependent Claim
58 words
A concrete canal bank retaining wall as in claim 1, wherein said retaining wall includes a substantially horizontal extension at the top of said inclined earthen canal bank, said horizontal extension being recessed into the ground so that the top surface thereof is substantially flush with the surface of the ground at the top of said canal bank.
Claim 5
Dependent Claim
30 words
A concrete canal bank retaining wall as in claim 3, wherein said expansion joint strips are in both said horizontal extension of said retaining wall and the inclined portion thereof.
Claim 6
Dependent Claim
30 words
A concrete canal bank retaining wall as in claim 4, wherein said earthen canal bank and said inclined retaining wall are inclined approximately 30* to 60* relative to the vertical.
Claim 7
Dependent Claim
47 words
A concrete canal bank retaining wall as in claim 1, wherein said retaining wall includes means therein defining removable sections which can be removed for the construction of boat slips, or cantilever or other type docks or the like without disturbing adjacent portions of said retaining wall.
Claim 8
Dependent Claim
69 words
A concrete canal bank retaining wall as in claim 6, wherein a separating means such as a sheet of plastic or the like positioned substantially horizontally and in a plane perpendicular to the plane of said inclined wall defines a separation area for the lower end of said removable section, and a pair of spaced apart expansion joint means define separation areas at the sides of said removable section.
Claim 9
Dependent Claim
26 words
A concrete canal bank retaining wall as in claim 7, wherein said lower end of said removable section is below the water line of said canal.
Claim 10
Dependent Claim
29 words
A concrete canal bank retaining wall as in claim 7, wherein said lower end of said removable section is at or suitably above the water line of said canal.
Claim 11
Dependent Claim
45 words
A concrete canal bank retaining wall as in claim 7, wherein said expansion joint strips comprise elongate strips of compressible material positioned edgewise on the inclined bank of said canal and extending perpendicularly from the earthen canal bank to the surface of said poured concrete.
Claim 12
Dependent Claim
121 words
A concrete retaining wall means for canal banks comprising: an inclined, elongate poured concrete wall poured directly on an inclined earthen canal bank; expansion joint means in said wall at spaced intervals therealong extending from the top of the wall toward the bottom thereof substantially perpendicular to the longitudinal axis of said wall, and separation strip means in said wall at spaced intervals therealong defining separation areas between adjacent sections of the wall so that sections of said wall between adjacent separation strips can be readily slid upwardly relative to adjacent sections on either side thereof and removed without disturbing adjacent sections of said wall for the construction of boat slips, boat ramps, cantilever and other design docks, and the like.
Claim 13
Dependent Claim
121 words
A concrete retaining wall means for canal banks comprising: an inclined, elongate poured concrete wall poured directly on an inclined earthen canal bank; expansion joint means in said wall at spaced intervals therealong extending from the top of the wall toward the bottom thereof substantially perpendicular to the longitudinal axis of said wall, and separation strip means in said wall at spaced intervals therealong defining separation areas between adjacent sections of the wall so that sections of said wall between adjacent separation strips can be readily slid upwardly relative to adjacent sections on either side thereof and removed without disturbing adjacent sections of said wall for the construction of boat slips, boat ramps, cantilever and other design docks, and the like.
Claim 14
Dependent Claim
17 words
A concrete canal bank retaining wall as in claim 11, wherein said retaining wall is reinforced concrete.
Claim 15
Dependent Claim
40 words
A concrete canal bank retaining wall as in claim 11, wherein a plurality of expansion joint means are in said wall and extend from the top of the Bank downwardly to at least approximately the water level of said canal.
Claim 16
Dependent Claim
30 words
A concrete canal bank retaining wall as in claim 13, wherein said expans1on joint means comprises a generally trough shaped member opening upwardly and supported on said earthen canal bank.
Claim 17
Dependent Claim
25 words
A concrete canal bank retaining wall as in claim 14, wherein said expansion joint extends from the top to the bottom of the canal bank.
Claim 18
Dependent Claim
49 words
A concrete canal bank retaining wall as in claim 15, wherein said trough shaped member comprises a first elongate portion extending from the top to the bottom of said inclined canal bank, and a second portion hingedly joined thereto and extending across the horizontal portion of said canal bank.
Claim 19
Dependent Claim
24 words
A concrete canal bank retaining wall as in claim 16, wherein said trough shaped member is filled with a mixture of vermiculite and cement.
Claim 20
Dependent Claim
44 words
A concrete canal bank retaining wall as in claim 17, wherein said trough shaped member has elongate anchoring ribs in the opposite sides thereof for holding said trough shaped member in place in said concrete as said concrete is poured on opposite sides thereof.
Claim 21
Dependent Claim
38 words
A concrete canal bank retaining wall as in claim 18, wherein the surface of said concrete retaining wall is roughened at least below the water line of said canal to provide shelter for marine life and the like.
Claim 22
Dependent Claim
38 words
A concrete canal bank retaining wall as in claim 19, wherein said roughened surface comprises stones placed on the surface of said wall, at least some of said stones embedded at least partially in said concrete retaining wall.
