Splice for a soil reinforcing element or connector
View Patent ↗A system and method of constructing a mechanically stabilized earth (MSE) structure. A wire facing is composed of horizontal and vertical elements. A soil reinforcing element has a plurality of transverse wires coupled to at least two longitudinal wires having lead ends that upwardly-extend. A bearing plate includes one or more longitudinal protrusions configured to receive and seat the upwardly extending lead ends and couple the soil reinforcing element to the wire facing, and in particular to the vertical element. Multiple systems can be characterized as lifts and erected one atop the other to a desired MSE structure height.
1. A method of splicing a soil reinforcing element to a grid-strip, comprising:
seating one or more transverse wires proximal a reinforcing end of the soil reinforcing element in one or more first transverse protrusions defined on a first wave plate;
seating one or more transverse wires proximal a splicing end of the grid-strip in one or more second transverse protrusions defined on a second wave plate;
laterally offsetting longitudinal wires of the soil reinforcing element from longitudinal wires of the grid-strip, such that the one or more transverse wires proximal the reinforcing end and the one or more transverse wires proximal the splicing end are spaced apart from each other by the longitudinal wires of the soil reinforcing element and the longitudinal wires of the grid-strip;
aligning a first perforation defined on the first wave plate with a second perforation defined on the second wave plate; and
extending a first connective device through the first and second perforations and securing the first connective device from removal and thereby clamping down on the longitudinal wires of the soil reinforcing element and the grid-strip.
2. The method of claim 1 , wherein the first connective device is a threaded bolt and securing the first connective device from removal comprises threading a nut to an end of the threaded bolt.
3. The method of claim 1 , further comprising:
aligning a third perforation defined on the first wave plate with a fourth perforation defined on the second wave plate; and
extending a second connective device through the third and fourth perforations and securing the second connective device from removal.
4. The method of claim 3 , wherein the second connective device is a threaded bolt and securing the second connective device from removal comprises threading a nut to an end of the threaded bolt.
5. A composite soil reinforcing element, comprising:
a soil reinforcing element having a first plurality of transverse wires coupled to at least two longitudinal wires, the soil reinforcing element having a wall end and a reinforcing end;
a grid-strip having a second plurality of transverse wires coupled to at least two longitudinal wires, the grid-strip having a splicing end; and
a splice coupling the reinforcing end of the soil reinforcing element to the splicing end of the grid-strip, the splice comprising:
a first wave plate defining one or more first transverse protrusions receiving and seating a corresponding number of the first plurality of transverse wires of the soil reinforcing element;
a second wave plate defining one or more second transverse protrusions receiving and seating a corresponding number of the second plurality of transverse wires of the grid-strip;
a first perforation defined on the first wave plate and a second perforation defined on the second wave plate; and
a first connective device extending through the first perforation and the second perforation to couple the first wave plate to the second wave plate and clamp down on the at least two longitudinal wires of the soil reinforcing element and the at least two longitudinal wires of the grid-strip,
wherein the at least two longitudinal wires of the soil reinforcing element are laterally-offset from the at least two longitudinal wires of the grid-strip such that the first plurality of transverse wires and the second plurality of transverse wires are spaced apart from each other by the at least two longitudinal wires of the soil reinforcing element and the at least two longitudinal wires of the grid-strip.
6. The composite soil reinforcing element of claim 5 , wherein the first plurality of transverse wires are equidistantly-spaced along the at least two longitudinal wires of the soil reinforcing element.
7. The composite soil reinforcing element of claim 5 , wherein the second plurality of transverse wires are equidistantly-spaced along the at least two longitudinal wires of the grid-strip.
8. The composite soil reinforcing element of claim 5 , wherein the first connective device is a threaded bolt.
9. The composite soil reinforcing element of claim 8 , wherein the threaded bolt is secured against removal by threading a nut to an end of the threaded bolt.
10. The composite soil reinforcing element of claim 5 , wherein the first plurality of transverse wires are irregularly-spaced along the at least two longitudinal wires of the soil reinforcing element.
11. The composite soil reinforcing element of claim 5 , wherein the second plurality of transverse wires are irregularly-spaced along the at least two longitudinal wires of the grid-strip.
12. The composite soil reinforcing element of claim 5 , further comprising:
a third perforation and a fourth perforation defined on the first wave plate;
a fifth perforation and a sixth perforation defined on the second wave plate, wherein the third and fifth perforations are axially-aligned and the fourth and the sixth perforations are axially-aligned; and
a second connective device extensible through the third perforation and the fifth perforation.
