CONCRETE REVETMENT Filed April 25, 1929 1 F w WED* Patented Mar. 1, 1932 STATES l MTEiur*or-Fier:
AREHR C. EVERHAM, OF KANSAS CITY, MISSOURI, ASSIGNOR TO RAYMOND CON CRETE n PILE COMPANY, OF NEW YORK,
N. Y., A COR-IEORA'IION' OF NEW JERSEY CONCRETE nEvn'rMEN'r Application med April 25,
This invention pertains to concrete revetments of a kind now being used to prevent washing away of river banks under flood conditions. This revetment comprises concrete slabs interconnected by longitudinal and crosswise wires to form an articulated mat. The individual slabs or units are usually about one foot wide, four feet long, and three inches thick, and the mats are usually about 140 feet wide and 250 to 300 feet long. The mats are assembled above water level and then lowered to position over the sides of barges.
rlhe principal object of the invention is to provide an improved revetment of such design as to tend to anchor itself in position on the river bed and thus better resistdisplacement, especially on inclined banks. This object is accomplished byy use of an improved slab or unit so shaped and reinforced as to save considerable material, without sacrifice of strength, as compared with slabs previously used. Or, if the same amount of material be used, the slab herewith disclosed willv give greatly increased'strength without adh ditional cost.
Further and other objects and advantages will be apparent from the accompanying specification and drawings, which by way of illustration show what is now considered the preferred embodiment of the invention.
Fig. 1 is a view of a fragment of an articulated mat.
Fig. 2 is an enlarged plan view of one of the slabs of which the mat is composed, with wires.
Fig. 3 is a perspective view of the lower side of the slab shown in Fig. 2.
Fig. 4 is a longitudinal cross-section of the mat in position on the bank.
Referring to Fig. l, the mat comprises a plurality of slabs 10, reinforced andtied together by longitudinal wires or cables 12 and by lateral wires or cables 14.
Referring to Figs. 2 and 3, it will be seen that the bottom of the slab is cut out to form recesses 16 and to leave ribs 18 lengthwise of the slab and ribs 20 crosswise thereof. Wires 14 are embedded in ribs 18 close to the surface thereof, and wires 12 are embedded 19295 serial Nt. 357,897.
infribs 20,`close to wires 14,- as may best be seen in Fig.'4. `This location'of lthe wires serves -to reinforce the slabs on their lower sides,`from which material has been removed,
so that no strength issacrificed due to such'- removal. Y It will be noted that the wires serve the double purpose of reinforcing the recessed part of the slab and of interconnecting the slabs to form the articulated mat. If desired, additional reinforcing may be added, as for instance at 22. Y
Fig. 4 shows how the ribs of the slabs settle into the bed of the river and how the material of the bed enters recesses 16 with the result that the mat is well anchored to the bed and is better adapted to resist movement relatively thereto than plain slabs without ribs and recesses. In addition to the mechanical resistance to movement provided by the shape of the slab, a suction resist-ance is encountered between the recessed portion of the slab and the soil, which tends to hold them in close relationship. The soil in the recess acts as a plunger and tends to create a vacuum or suction when withdrawn from the recess.
It is to be understood that the invention is not limited to the specific embodiment herein illustrated and described but may be used in other ways without departure from the spirit of the claims.
I claim- 1. A revetment comprising a plurality of slab-like kbodies each having depending ribs integral with said body and bounding said body on its sides and ends to form a soil pocket and reinforcing elements embedded in and co-extensive with the ribs on all sides of the pocket, said reinforcing wires extending from the sides and ends and similarly reinforcing other slabs held in spaced relation by said wires to form an articulated mat.
2. A revetment comprising a plurality of slab-like bodies, each having depending ribs integral with said body and bounding said body on its sides and ends to form a soil pocket, a partition rib connecting the ribs on the side of the body to divide the pocket into two parts, and reinforcing elements embedded in and co-extensive with the ribs on all sides of the pockets, said reinforcing wires extending from the sides and ends and similarly reinforcing other slabs held in spaced relation by said wires to form an articulated mat.
3. An article of manufacture comprising a revetment slab having a lower surface partly cut away whereby recesses surrounded by longitudinal and cross ribs are provided, said cross ribs having reinforcing wires embedded therein, and said longitudinal ribs having reinforcing wires embedded therein and coeXtensive therewith on opposite sides of the cross ribs and between said cross wires and the upper and lower surface of said ribs said reinforcing wires extending from the sides and ends of said slab and entering and reinforcing similar slabs held in spaced relation by said wires to form an articulated mat.
In testimony whereof I hereto affix my signature. e
ARTHUR C. EVER-HAM.
