Abstract
Description
- The present invention relates to precast concrete culvert or bridge assemblies or systems such as disclosed in U.S. Pat. Nos. 4,993,872 and 6,854,928 which issued to the assignee of the present invention and the disclosures of which are herein incorporated by reference. In a culvert or bridge assembly as disclosed in the '872 Patent, a plurality of one-piece and open bottom culvert or bridge units or sections are precasted of concrete with reinforcement and include parallel spaced side walls integrally connected by an arcuate top wall. Curved surfaces connect the inner surface of the arcuate top wall to the opposing inner surfaces of the side walls, and the outer surface of the top wall form angular corners with the outer vertical surfaces of the side walls. The construction of an open bottom precast concrete culvert or bridge section as disclosed in the above '872 Patent is satisfactory and usable up to a span between the side walls of about forty eight feet. However, it has been found that there is a need for one-piece open bottom precast concrete bridge sections each having a span significantly above forty-eight feet, for example, a span of sixty feet.
- The present invention is directed to an improved precast concrete bridge assembly and which is formed by a plurality of one-piece precast concrete bridge sections each having a span greater than fifty feet and capable of supporting the substantial loads of the compacted soil surrounding the bridge assembly as well as the loads of a roadway extending above the bridge assembly and the motor vehicle traffic on the roadway. In accordance with one embodiment of the invention, each of the precast reinforced concrete bridge units or sections includes parallel spaced side walls integrally connected by an arcuate top wall, and the opposing inner surfaces of the side walls define a span between fifty and seventy-five feet. The arcuate top wall of each section has a radius of curvature between sixty-five and eighty feet, and the rise between the bottom surfaces of the side walls and the inner top surface of the top wall is between ten and fourteen feet. The substantially vertical outer surfaces of the side walls have a height between five and nine feet, and curved surfaces connect the inner surfaces of the side and top walls and have a radius of curvature between five and seven feet.
- Other structural features and advantages of the invention will be apparent from the following description, the accompanying drawings and the appended claims.
-
FIG. 1 is a perspective view of a precast concrete bridge assembly constructed in accordance with the invention and with intermediate bridge sections removed to illustrate an indefinite length for the assembly; and -
FIG. 2 is an end view of each bridge section shown inFIG. 1 . - Referring to
FIG. 1 , a precastconcrete bridge assembly 10 includes a plurality of aligned open bottom precast concrete bridge units orsections 15 each of which is reinforced, for example, by steel rebars and/or steel mesh as disclosed in above-mentioned U.S. Pat. No. 4,993,872. Each of the one-piece bridge sections 15 includes parallel spacedside walls 18 having substantially verticalouter surfaces 17 andinner surfaces 19, and the side walls are integrally connected by an arcuatetop wall 20. The span S (FIG. 2 ) define between theinner surfaces 19 of theside walls 18 is greater than fifty feet and less than seventy-five feet, for example, fifty-four feet or sixty feet. The rise R of eachbridge section 15, as defined between the bottom surfaces of theside walls 18 and the top of aninner surface 22 of thetop wall 20 is greater than ten feet and less than fourteen feet, for example, about eleven feet for a span S of fifty-four feet and about twelve feet for a span S of sixty feet. The height H of theouter surface 17 of each side wall is within the range of five feet and nine feet, for example, six feet. - The
inner surface 22 of the arcuatetop wall 20 of thebridge section 15 has a radius of curvature R1 which is greater than sixty five feet and less than eighty feet, for example, on the order of seventy feet. The thickness T1 of the central portion of thetop wall 20 is greater than twelve inches and preferably greater than thirteen inches and less than sixteen inches, for example, fourteen inches. The arcuatetop surface 23 of thetop wall 20 continues with a substantially uniform radius on each side of a center reference plane P and through an angle A of about twenty-four degrees and then continues with an outerflat surface 26 having a length L2 of about three and one half feet. - The radius R1 of the
inner surface 22 of thetop wall 20 is uniform through an angle B of about seventeen degrees on each side of the center plane P and then continues with a smaller radius of curvature R3, for example, thirty-three feet, through an angle C of about twelve degrees. Theinner surface 19 of eachside wall 18 connects with theinner surface 22 at thetop wall 20 by acurved surface 28 having a radius of curvature R2 greater than five feet and less than seven feet, for example, six feet. The radius R2 extends through an angle D of about sixty degrees to form a corner thickness T3 of about three feet. The lower portions of theside walls 18 have a thickness T between fifteen and nineteen inches, for example, on the order of sixteen inches to eighteen inches, and thesurface 26 at each end of thetop wall 20 forms a corner angle E of about 113 degrees with theouter surface 17 of thecorresponding side wall 18. The length L (FIG. 1 ) of eachbridge section 15 is on the order of four feet. - From the above dimensions and range of dimensions for each
bridge section 15, it is apparent that the radius R1 of the arcuatetop wall 20 is at least five times the rise R, at least seven times the height H of theside walls 18 and at least eleven times the radius R2 of the innercurved surface 28. By constructing eachunderground bridge section 15 with the configuration shown inFIGS. 1 & 2 and with the angles and dimensions within the ranges set forth above, it has been found that thebridge assembly 10 provides not only for supporting the compacted soil back-filled around the bridge assembly, but also provides for a distinctive and aesthetically pleasing appearance. - While the form and profile of the bridge assembly herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form and profile and that changes may be made therein without departing from the scope and spirit of the invention as defined in the appended claims.
