That is, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. However, these examples should not be construed in a limiting sense as they are merely intended to provide examples of the invention rather than to provide an exhaustive list of all possible implementations of the invention.

[0042] Specific embodiments of the invention will now be further described by the following, non-limiting examples which will serve to illustrate various features. The examples are intended merely to facilitate an understanding of ways in which the invention may be practiced and to further enable those of skill in the art to practice the invention. Accordingly, the examples should not be construed as limiting the scope of the invention. In addition, reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

[0043] FIG. 1 is a perspective view of the traffic barrier soundwall (TBSW). Shown is a TBSW segment having a precast bottom portion 100 which retains a precast top portion 200. The bottom portion 100 is installed in the ground with reinforcement as described herein and the top portion 200 is disposed on top of the bottom portion. In the depicted embodiment the assembled TBSW is 16 feet tall, but when installed in the ground the total stanchion wall height is 14 feet, with the footer 2 foot under the ground. In some embodiments, a plurality of top portions 200 can be stacked on one another to achieve a taller overall barrier wall. Connection plates 800 can be used to connect adjacent segments.

[0044] FIG. 2A is a schematic view of the TBSW showing the top portion 200 exploded away from the bottom portion 100. FIG. 2B is a close up of the bottom portion 100 In some embodiments, the top portion 200 is secured to the bottom portion 100 by a high-strength epoxy. One or more corrugated metal pipe sections 101 are disposed along the top edge of the bottom portion which receive retaining dowel rods 201 extending from the bottom edge of the top portion (see FIG. 10). In some embodiments, the pipe sections 101 are filled with grout or other filler. In some embodiments, a high strength epoxy is used to secure the top portion to the bottom portion. Further still, a silicone sealant may be used around the joints to finalize the connection and to block noise transmission. In some embodiments the upper corners of each of the top and bottom portions include expansion troughs 102 and 202 (202 shown in FIGS. 15A-15B), respectively, which allow for connection to an adjacent TBSW segment. In some embodiments, the expansion troughs 102 and 202 are configured to accept and retain fasteners and other hardware in order to mechanically connect adjacent segments. The troughs 102 and/or 202 may also be flooded with a filler material such as grout, concrete, or epoxy in order to enhance the connection, cover hardware, and provide a finished look.

[0045] FIGS. 3A-3B and 4A-4B are top plan views of two embodiments of the TBSW segments configured as complete soundwall barriers installed adjacent to a road, such as a highway or expressway. FIGS. 5A-5C and 6A-6C are corresponding front elevation views. In some embodiments, the TBSW segments include voids 300 to accommodate structure such as median barriers and other elements. FIGS. 7A-7B are front elevations views of a sloped end or transition TBSW segment.

[0046] With reference to FIGS. 8A-8L, shown are various embodiments of the TBSW segments having varying shapes and relative dimension. As shown, “Type A” segments have generally rectangular top portions to form a wall of a uniform height In some embodiments, transition segments are implemented, such as “Type B,” “Type C”, “Type D,” “Type E,” and “Type F,” which have top portions 100 of various shape and dimensions.

[0047] FIG. 9A is a cutaway elevation view of the bottom portion 100 of the TBSW showing its reinforcement structure. Here, a matrix or lattice 500 of reinforcing bar (rebar) is disposed at the interior of the bottom portion. Also shown are one or more lifting loops 400 along the top edge of the bottom portion which are used as attachment points to facilitate handling, moving, locating, and installing the segments. In some embodiments, the lifting loops 400 are coextensive with the rebar matrix 500. FIG. 9B shows a close up of the lifting loop 400, with the dotted lines showing the available expansion of the loop 400 to tie into reinforcing steel or other structure.

[0048] FIG. 10A is a cross-section view of the bottom portion 100 of a TBSW segment. Here it is seen that the cross-section is generally T-shaped although in some embodiments the stanchion wall (“leg” of the T) tapers outwardly on one side toward the footer 103 (base of the “T”). The footer 103 is configured to be disposed under the surface of the ground with the stanchion wall extending upward therefrom. Here the various rebar sections are shown disposed at the interior of the bottom portion, including the stanchion wall and footer. Also shown is the fitment of the dowel rods 201 of the top portion 200 into the pipe sections 101 of the bottom portion 100.

[0049] Alternatively, as shown in FIG. 11, a combination of mesh (dotted lines) and rebar (solid lines) may be used as reinforcement, with the mesh disposed vertically along the interior of the stanchion wall and horizontally along the interior of the base section, with at least a portion of the rebar disposed perpendicular to the mesh. FIG. 12 shows an embodiment of a mesh matrix 600 forming at least a portion of the reinforcement.

[0050] FIGS. 13A-13C show embodiments of the TBSW segments having voids to accommodate additional structures such as a median barrier 700.

[0051] FIG. 14 is an elevation view of top portion 200 of the TBSW showing its reinforcement structure. Rebar is provided in a grid or matrix 500 configuration as shown. The grid 500 may also include trimmable rebar sections 501 at the corners of the top portion 200 to clear notches and other geometry. Lifting loops 400 are also provided which, like the lifting loops on the bottom portion, may be coextensive with the rebar. Also show are the dowel rods 201 extending down from the bottom edge of the top portion, which fit into the pipe sections along the top edge of the bottom portion 100 (not shown).

[0052] FIGS. 15A-15B are cross-section end views showing the connection of the top portion 200 to the bottom portion 100 including the insertion of the down rod 201 into the pipe section 101. Also shown expansion troughs 202 at the top edge of the top portion 100 which can be used to accommodate connections such as brackets to attached adjacent top portions 200.

[0053] It is to be noticed that the term “comprising,” used in the claims, should not be interpreted as being limitative to the means listed thereafter. Thus, the scope of the expression “a device comprising means A and B” should not be limited to devices consisting only of components A and B. It means that with respect to the present invention, the only relevant components of the device are A and B. Put differently, the terms “including”, “comprising” and variations thereof mean “including but not limited to”, unless expressly specified otherwise.

[0054] Similarly, it is to be noticed that the term “coupled”, also used in the claims, should not be interpreted as being limitative to direct connections only. Thus, the scope of the expression “a device A coupled to a device B” should not be limited to devices or systems wherein an output of device A is directly connected to an input of device B. It means that there exists a path between an output of A and an input of B which may be a path including other devices or means.
