Definitions

  • the present application relates to the general art of structural, bridge and geotechnical engineering, and to the particular field of concrete bridge and culvert structures.
  • Overfilled bridge structures are frequently formed of precast or cast-in-place reinforced concrete and are used in the case of bridges to support a first pathway over a second pathway, which can be a waterway, a traffic route, or in the case of other structures, a buried storage space or the like (e.g., for stormwater detention).
  • the term "overfilled bridge” will be understood from the teaching of the present disclosure, and in general as used herein, an overfilled bridge is a bridge formed of bridge elements or units that rest on a foundation with soil or the like resting thereon and thereabout to support and stabilize the structure and in the case of a bridge to provide the surface of (or support surface for) the first pathway.
  • a variation of the historic flat-top shape has also been introduced, as shown in U.S. Patent No. 7,770,250 , that combines a flat, horizontal top with an outwardly flared leg of uniform thickness.
  • the resulting shape provides some improvements to hydraulic efficiency versus the flat-top by adding open area and also provides some improvement structurally by flattening the angle between the top and legs to about one-hundred ten degrees.
  • flattops are severely limited in the ability to reach longer spans needed for many applications (e.g., the effective limit for flat top spans is in the range of 9.14 to 12.19 m (thirty to forty feet)).
  • FR 2599783 A1 discloses, in Fig 3 , a multi-channel culvert assembly comprising first and second culvert units, each having an arched top wall, a curved outer side wall, a vertical inner side wall and a base forming a closed channel.
  • the vertical inner side walls are spaced from each other and joined together by a further arched top wall.
  • the present invention consists in a multi-channel culvert assembly, comprising: a first culvert unit having an arch-shaped top wall, a first side wall extending substantially vertically downward from the top wall and a second sidewall extending downward and outward from the top wall; a second culvert unit having an arch-shaped top wall, a first side wall extending substantially vertically downward from the top wall and a second side wall extending downward and outward from the top wall; wherein the first culvert unit is positioned with its first side wall toward an inner part of the assembly and the second culvert unit is positioned with its first side wall toward an inner side of the assembly to create first and second channels of the assembly, the first channel beneath the first culvert unit, the second channel beneath the second culvert unit, wherein the first channel has an inner side that is substantially vertical and an outer side that is angled from vertical and the second channel has an inner side that is substantially vertical and an outer side that is angled from vertical; characterized in that: said first culvert unit and said second culvert unit
  • the first culvert unit and the second culvert unit may be identical in shape and size.
  • the substantially planar inner and outer surfaces of the second side wall of the first culvert unit are non-parallel whereby the second sidewall is tapered from top to bottom such that a thickness of the second side wall of the first culvert unit decreases when moving from top to bottom; and the substantially planar inner and outer surfaces of the second side wall of the second culvert unit are non-parallel whereby the second sidewall of the second culvert unit is tapered from top to bottom such that a thickness of the second side wall of the second culvert unit decreases when moving from top to bottom.
  • the culvert unit 10 includes an open bottom 12, a top wall 14 and spaced apart side walls 16 to define a passage 18 thereunder.
  • Each of the side walls has a substantially planar inner surface 20 and a substantially planar outer surface 22.
  • the top wall has an arch-shaped inner surface 24 and an arch-shaped outer surface 26 and a substantially uniform thickness T TW .
  • the arch-shaped inner surface and arch-shaped outer surface can each be made up of or defined by (i) a respective single radius, (ii) a respective set of joined radiuses (e.g., the surface is curved along its entire length) or (iii) in some cases planar sections may be included either the most center region of each arch-shaped surface or at the end portion of each arch-shaped surface.
  • planar sections may be included either the most center region of each arch-shaped surface or at the end portion of each arch-shaped surface.
  • Haunch sections 28 join each side wall 16 to the top wall 14.
  • Each haunch section has a corner thickness T HS greater than the thickness T TW of the top wall.
  • the corner thickness T HS is measured perpendicular to the curved inner surface 30 of the haunch section along a line that passes through the exterior corner 32 of the haunch section. While the larger corner thickness of a unit as compared to the side wall and top wall thickness of the same unit is critical to the structural performance of the unit, the present culvert unit is configured to more effectively distribute load from the top wall to the side walls of the present culvert unit so that the corner thickness of the present culvert unit can be reduced in comparison to prior art culvert units.
  • an interior side wall angle ⁇ ISWA between the side wall 16 and the top wall 14 is defined by intersection of a plane 34 in which the inner surface of the side wall lies and a line or plane 36 that is tangent to the inner surface 24 of the top wall at the point or line 38 where the top wall inner surface 24 meets the haunch inner surface 30 (e.g., where the inner surface of the unit transitions from the radius R TW to the radius R H defining the inner surface haunch).
  • the plane 36 is perpendicular to the radius R TW that defines the arch-shaped inner surface of the top wall at a point 38 where the radius R TW stops and the radius R H starts.
  • R TW will define the entire span of inner surface 24 from haunch to haunch.
  • the center portion of the top wall inner surface 24 may be defined by one radius and the side portions of the inner surface 24 may be defined by a smaller radius R TW .
  • the illustrated unit 10 is constructed such that the interior side wall angle ⁇ ISWA is at least one-hundred and thirty degrees, and more preferably at least one-hundred thirty-three degrees.
  • This relative angle between the top wall and side wall reduces bending moment in the haunch section as compared to prior art units, enabling the thickness of the haunch sections 28 to be reduced and the amount of steel used in the haunch sections to be reduced, resulting in a reduction in material needed, along with a corresponding reduction in unit weight and material cost per unit.
  • the center of gravity of the overall unit is moved downward by reducing concrete in the haunch sections, thereby placing the center of gravity closer to the midway point along the overall height or rise of the unit.
  • an exterior side wall angle ⁇ ESWA between the top wall 14 and the side wall 16 is defined by intersection of a plane 42 in which the outer surface 22 of the side wall lies and a line or plane 44 that is tangent to the top wall outer surface 26 at the point or line 46 where the outer surface 26 intersects the plane 42. It is noted that for the purpose of evaluating the exterior side wall angle the outer surface of the top wall is considered to extend along the full span at the top of the unit (e.g., from corner 32 to corner 32).
  • the radius that defines the outer surface 26 of the top wall near the corners 32 may typically be R TW + T TW , but in some cases the radius of the outer surface 26 in the corner or end region may vary. In other cases, particularly for larger spans, as shown in Fig. 4A , the corner or end regions of outer surface 26 may include planar end portions 27, in which case the plane 44' would in fact be perpendicular to the radius (e.g., R TW + T TW ) that defines the outer surface 26 at the point or line 29 where that radius (e.g., R TW + T TW ) meets the planar end portion 27 of the surface 26.
  • the exterior side wall plane 42 is non-parallel to the interior side wall plane 34, such that each side wall 16 is tapered from top to bottom, with thickness along the height of the side wall decreasing when moving from the top of each side wall down toward the bottom of each side wall.
  • the thickness of the side wall T SW at any point along it height is taken along a line that runs perpendicular to the interior side wall plane 34 (e.g., such as line 48 in Fig. 4 ).
  • the thickness at the bottom of each side wall may be no more than about 90% of the thickness of the top wall, resulting in further concrete savings as compared to units in which all walls are of uniform and common thickness.
  • the exterior side wall angle is different than the interior side wall angle, and is significantly greater than angles used in the past, such that the exterior side wall angle ⁇ ESWA is at least one-hundred and thirty-five degrees and, in many cases, at least one-hundred and thirty-eight degrees.
  • An angle of intersection ⁇ PI between the plane 34 in which the inner surface lies and the plane 42 in which the outer surface lies may be between about 1 and 20 degrees (e.g., between 1 and 4 degrees), depending upon the extent of taper, which can vary as described in further detail below.
  • the angle ⁇ PI is preferably at least about 2-4 degrees.
  • the configuration of the culvert section 10 allows for both hydraulic and structural efficiencies superior to previously known culverts.
  • the hydraulic efficiency is achieved by a larger bottom span that is better capable of handling the more common low flow storm events.
  • the structural efficiency is achieved by the larger side wall to top wall angle that enables the thickness of the haunch to be reduced, and enabling more effective longer span units (e.g., spans of 48 feet and larger).
  • the reduced corner thickness and tapered legs reduce the overall material cost for concrete, and enables the use of smaller crane sizes (or longer pieces for the same crane size) during on-site installation due to the weight advantage.
  • the tapered side wall feature described above can be most effectively utilized by actually varying the degree of taper according to the rise to be achieved by the precast concrete unit.
  • the rise of a given unit is defined by the vertical distance from the bottom edges 50 of the side walls 16 to top dead center 52 of the arch-shaped inner surface 24 of the top wall 14.
  • rise R1 being the rise for the unit shown in Figs. 1-3
  • rise R2 being a smaller rise
  • rise R3 being a larger rise.
  • the side wall taper varies as between the three different rises, utilizing a constant top span S TW defined as the horizontal distance between the haunch corners 32.
  • the side wall taper is more aggressive in the case of the smaller rise R2 as demonstrated by the exterior side wall surface 22' shown in dashed line form, and the side wall taper is less aggressive in the case of the larger rise R3 as demonstrated by the exterior side wall surface 22" shown in dashed line form.
  • This variation in taper is achieved by varying the exterior side wall angle ⁇ ESWA ( Fig. 4 ) according to the rise or bottom span for the unit that is to be produced.
  • Each bottom span (S BR1 , S BR2 , S BR3 ) is defined as the horizontal distance between the bottom edges of the side wall inner surfaces 20.
  • the bottom span is preferably greater than the radius of curvature R TW of the arch-shaped inner surface of the top wall at top dead center in order to provide more effective waterway area for lower flow storm events (e.g., in the case of creek or stream crossings).
  • R TW radius of curvature
  • the inner surface 20 of the side walls varies in length over the different rises, but the interior side wall angle does not vary.
  • a form system in which, for each side wall, an interior form structure portion for defining the interior side wall angle is fixed and an exterior form structure portion defining the exterior side wall angle can be varied by pivoting.
  • the pivot point for each exterior form structure portion is the exterior corner 32 of the haunch section.
  • the exterior form structure portion is pivoted to a position that sets the appropriate exterior side wall angle and the exterior form structure portion is locked in position.
  • the form structure is then filled with concrete to produce the culvert section.
  • the form 60 is placed on its side for the purpose of concrete fill and casting.
  • a form seat 62 is provided for each side wall, with the interior form structure portion 64 seating alongside the edge of the form seat 62 as is typical in precasting of bridge units.
  • the exterior form structure portion 66 which pivots about a hinge axis 68, has its bottom edge raised (relative to the bottom edge of portion 64) so that portion 66 can move across the top surface of the form seat 62 during pivot.
  • the exterior side wall angle may, in each case, be achieved by establishing a consistent horizontal width W SB ( Fig. 2 ) for the bottom surface of the side wall for a given top span S TW , regardless of the rise being produced.
  • the form system includes a bottom form panel member 63 that is movable along the height of the form portion 64 and can be bolted in place using bolt holes 69 provided in the form structure 64. Similar bolt holes would be provided in the edge 67 of panel 63, and the edge 67 would be angled to match the surface of form portion 64 so that surface 65 of the panel will be horizontal when installed. Any unused bolt holes would be filled with plug members.
  • each haunch section 28 is defined by an inner surface 30 with a radius of curvature R H , and the inner surface 20 of each side wall intersects with the inner surface of its adjacent haunch section 28 at an interior haunch intersect line or point 70, which is the point of transition from the planar surface 20 to the radiused surface 30.
  • a vertical distance D IT between the height of the defined interior haunch intersect line 70 and the height of top dead center of the arch-shaped inner surface of the top wall should be no more than about eighteen percent (18%) of the radius of curvature R TW of the arch-shaped inner surface 24 of the top wall at top dead center in order to more effectively reduce the haunch corner thickness.
  • a ratio of the vertical distances D OT /D IT should preferably be no less than about 55% and, more preferably, no less than about 58%.
  • the exterior corner 32 of the haunch section 28 is spaced laterally outward of the interior haunch intersect line 70 by a relatively small distance, and particularly a horizontal distance that is less than the horizontal width W SB of the side wall bottom surface.

  • each side wall 16 In some cases it is desirable to provide a vertical flat segment 80 at the bottom portion of each side wall 16.
  • the vertical flat 80 facilitates the use of blocking structure (e.g., wooden blocks 82 with corresponding vertical surfaces) in combination with the keyway/channel 84 in concrete footing 85 to hold the culvert sections in place, preventing the bottom ends of the side walls from moving outward under the weight of the culvert section, until the bottom ends are grouted/cemented in place.

  • the concrete culvert section typically includes embedded reinforcement 110 and 112 generally running in proximity to and along the inner and outer surfaces of the top wall 14 and side walls 16.
  • concrete culverts of varying rises can be achieved by maintaining the outside corners of the top wall in the same position, but pivoting the outside surface of each side wall outward for larger rises, or inward for smaller rises.
