DETAILED DESCRIPTION
[0019] A multi-sided culvert generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 10.
[0020] Referring to FIG. 6, multi-sided culvert 10 has a culvert body 12 formed from three separate bodies, used as a base section 14, a first side body 16 and a second side body 18. It will be understood that the designation as a base, first or second body relates primarily to the function of the component. As will be discussed below, the design or shape of the bodies may be interchangeable or the same. Furthermore, while the bodies are all shown as 5 being planar, it will be understood that some or all may have different shapes, such as a curved section to increase the volume. On the other hand, it may be preferable to provide base section 14 and possibly others with a flat surface, such as to simplify installation.
[0021] First side body 16 and second side body 18 are supported by base section 14, which engages first side body 16 with a first bottom engagement 24, and second side body 18 with a second bottom engagement 26. First side body 16 and second side body 18 are engaged at a top 20 of culvert body 12 by a top engagement 22. As shown in FIG. 6, each of the first, second and top engagements 24, 26 and 22 may use a similar shape to form the engagement and each of the three side bodies 14, 16, and 18 carry one part of a two-part connection at either end, allowing for connections to be formed at the corners when assembled, as shown in FIG. 6. However, it will be understood that alternate engagements may be used, some of which are described below. In one example, referring to FIG. 5 and with respect to top engagement 22, first side body 16 and second side body 18 may have flat top engagement surfaces, and use a secondary connector 23, such as a pin connection or clamp, to form top engagement 22.
[00221 Referring to FIG. 2, first bottom engagement 24 is depicted as having a first part 28 at a first side edge 30 of base 14 and a second part 36 at a first side edge 38 of first side 16, and is formed by engaging first and second parts 28 and 36. First part 28 has a first guide section 32 and a first interlocking section 34. Second part 36 has a second guide section 40 and a second interlocking section 42, each of which are shown as being complementary to first guide section 32 and first interlocking section 34, respectively. When first bottom engagement 24 is being formed, first and second guide sections 32 and 40 interact to guide first and second interlocking sections 34 and 42 into interlocking engagement, as shown in FIG. 3. First and second interlocking sections 34 and 42 have tapered surfaces 44 and 46 that, when engaged, permit upward and outward movement of second part 36 relative to base 14.
Referring to FIG. 7 and 8, first bottom engagement 24 may have either arrangement of components.
[0023] The engagement described above is preferably used as the basis for the other engagements used in culvert body 12, although it may be used in different ways. For example, as shown in FIG. 5, first bottom engagement 24 and second bottom engagement 26 may be symmetric, with having the arrangement shown in FIG. 7, such that second bottom engagement 26 has a first part 48 at a second side edge 50 of base 14 that is shaped the same as first part 28 of first bottom engagement 24 and a second part 52 at a first side edge 30 of second side body 18 that is shaped the same as second part 36 of first bottom engagement 24.
Alternatively, referring to FIG. 2, second bottom engagement 26 may have a first part 48 at a second side edge 50 of base 14 that is shaped the same as second part 36 of first bottom engagement 24 and a second part 52 at a first side edge 54 of second side body 18 that is shaped the same as first part 28 of first bottom engagement 24.
[0024] Referring to FIG. 4, top engagement 22 may have a first part 56 at a second side edge 58 of first side body 16 that is shaped the same as first part 28 of first bottom engagement 24 and a second part 60 at a second side edge 62 of second side body 18 that is shaped the same as second part 36 of first bottom engagement 24. As shown in HG. 4, when top engagement 22 is provided as described, each of base 14, first side body 16, and second side body 18 have a common size and shape, which may be used to simplify manufacturing and handling procedures. In another example, top engagement 22 may have a first part 56 at second side edge 62 of second side body 18 that is shaped the same as first part 28 of first bottom engagement 24 and a second part 60 at a second side edge 58 of first side body 16 that is shaped the same as second part 36 of first bottom engagement 24. For example, first side body 16 and second side body 18 may each be symmetrical, assuming base 14 has a different engagement profile at either side edge.
[0025] Referring to FIG. 7, in the depicted example, first guide section 32 of first part 28 has a flat surface 64 adjacent to a tapered surface 66 that descends from flat surface 64 toward first side edge 30 of base 14, first interlocking section 34 of first part 28 has a protrusion 68 that extends upward from flat surface 64 of first guide section 32. Second guide section 40 of second part 36 is complementary to first guide section 32, and second interlocking section 42 has a recess 70 that receives protrusion 68 of first interlocking section 34.
Alternatively, referring to FIG. 8, first guide section 32 of first part 28 has a flat surface 72 adjacent to first side edge 30 of base 14 and a tapered surface 74 that extends upward and away from flat surface 72 relative to first side edge 30 of base 14, and first interlocking section 34 of first part 28 has a recess 76 that is recessed from a top 78 of tapered surface 74.
Second guide section 40 of second part 36 is complementary to first guide section 32, and second interlocking section 42 has a protrusion 80 that is received by recess 76 of first interlocking section 34.
When engaged, the respective engagements may act as a labyrinth seal, or a mechanical seal that provides a tortuous path to help prevent leakage, through the corners of the culvert, thus ensuring that as much water as possible is diverted through the culvert, and does not leak into the surrounding area.
[0026] The angles of the various surfaces of the first and second parts of the engagements are selected such that the joints remain engaged and are biased toward engagement, but also permit some expansion when pressure is applied from within. For example, in the winter, water may freeze within culvert 12. The depicted engagements permit some movement to allow the freezing water to expand without damaging the culvert. As can be seen, there are surfaces at either end of the various bodies that are generally perpendicular to the respective body, or in other words, which are generally tangential to an arc that would be followed if the body were to pivot about its other end. These surfaces allow each body to slide outward in response to a force applied to the inner surface of culvert 12, while still being urged by gravity and the slope of that and other surfaces toward engagement.
[0027] The assembly of multi-sided culvert 10 will now be described.
Referring to FIG.
1, a base 14, is placed in an installation location. The installation location may be prepared by levelling or packing a material, such as road crush or gravel. Referring to FIG. 2 and 3, first and second side bodies 16 and 18 are then guided into place. As bodies 14, 16 and 18 may be quite heavy, they are preferably outfitted with lifting rings or apertures (not shown), such that they can be manipulated by a lifting crane, hoist, or other device. If bodies 14, 16 and 18 are cast from concrete, lifting cables or rings may be embedded as part of the casting process. As shown with first engagement 24, where base body 14 has a convex guide surface 32, it may be easier to slide surface toward the edge of base body 14, such that second guide section engages first guide section 32 and causes first body 16 to pivot and form first engagement 24.
As shown with second engagement 26, where base body 14 has a concave shape and second body 18 has a convex shape, the edge of second body 18 may be placed directly on first part 48 of base body 14, and the respective shapes will allow second engagement 26 to be engaged as second body 18 pivots about the bottom edge. It will be understood that the order of installation of first side body 16 and second side body 18 will depend on the type of top engagement 22 provided. For example, each side may be lowered simultaneously, or one may be lowered first and the second installed afterwards. Alternatively, it may be necessary to suspend one or both of first and second bodies 16 and 18 in a partially open position, and move them to a fully installed position either simultaneously, or in a coordinated manner, to ensure the respective engagement profiles are properly mated. Once the three bodies 14, 16, and 18 have been installed, the tapered surfaces of the connections will permit relative movement of the side panels while maintaining engagement, allowing for the multi-sided culvert to expand and contract, such as in response to freezing of water within the culvert.
[0028] Referring to FIG. 9 and FIG. 10, multi-sided culvert 10 may optionally have an engaging profile 82 along the edge of each of the side bodies 14, 16, and 18.
As depicted, engaging profile 82 is provided along the length of the engagements 22, 24, and 26, and has alternating protrusions and recesses that engage during installation of multi-sided culvert 10.
Engaging profile 82 may aid in the installation process by aligning the side bodies for forming connections. As well, engaging profile 82 may serve to prevent shifting of the side bodies along the engagements 22, 24, or 26. It will be understood that engaging profile 82 may take other forms that engage the respective edges and limit sliding movement of the side bodies, such as having different numbers of protrusions and recesses, having shaped profiles, or having a series of notches and recesses.
[0029] Base 14, side body 16, and side body 18 may be formed from any suitable material, as will be understood by those skilled in the art. For example, the three panels may be cast from cement, concrete, or any other material suitable for use as a culvert. In the configuration shown in FIG. 3, first side body 16 and second side body 18 have a top engagement 22 that also forms an interlocking connection. In other embodiments, such as the one in FIG. 5, after first side body 16 and second side body 18 are installed, top engagement
[00221 Referring to FIG. 2, first bottom engagement 24 is depicted as having a first part 28 at a first side edge 30 of base 14 and a second part 36 at a first side edge 38 of first side 16, and is formed by engaging first and second parts 28 and 36. First part 28 has a first guide section 32 and a first interlocking section 34. Second part 36 has a second guide section 40 and a second interlocking section 42, each of which are shown as being complementary to first guide section 32 and first interlocking section 34, respectively. When first bottom engagement 24 is being formed, first and second guide sections 32 and 40 interact to guide first and second interlocking sections 34 and 42 into interlocking engagement, as shown in FIG. 3. First and second interlocking sections 34 and 42 have tapered surfaces 44 and 46 that, when engaged, permit upward and outward movement of second part 36 relative to base 14.
Referring to FIG. 7 and 8, first bottom engagement 24 may have either arrangement of components.
[0023] The engagement described above is preferably used as the basis for the other engagements used in culvert body 12, although it may be used in different ways. For example, as shown in FIG. 5, first bottom engagement 24 and second bottom engagement 26 may be symmetric, with having the arrangement shown in FIG. 7, such that second bottom engagement 26 has a first part 48 at a second side edge 50 of base 14 that is shaped the same as first part 28 of first bottom engagement 24 and a second part 52 at a first side edge 30 of second side body 18 that is shaped the same as second part 36 of first bottom engagement 24.
Alternatively, referring to FIG. 2, second bottom engagement 26 may have a first part 48 at a second side edge 50 of base 14 that is shaped the same as second part 36 of first bottom engagement 24 and a second part 52 at a first side edge 54 of second side body 18 that is shaped the same as first part 28 of first bottom engagement 24.
[0024] Referring to FIG. 4, top engagement 22 may have a first part 56 at a second side edge 58 of first side body 16 that is shaped the same as first part 28 of first bottom engagement 24 and a second part 60 at a second side edge 62 of second side body 18 that is shaped the same as second part 36 of first bottom engagement 24. As shown in HG. 4, when top engagement 22 is provided as described, each of base 14, first side body 16, and second side body 18 have a common size and shape, which may be used to simplify manufacturing and handling procedures. In another example, top engagement 22 may have a first part 56 at second side edge 62 of second side body 18 that is shaped the same as first part 28 of first bottom engagement 24 and a second part 60 at a second side edge 58 of first side body 16 that is shaped the same as second part 36 of first bottom engagement 24. For example, first side body 16 and second side body 18 may each be symmetrical, assuming base 14 has a different engagement profile at either side edge.
[0025] Referring to FIG. 7, in the depicted example, first guide section 32 of first part 28 has a flat surface 64 adjacent to a tapered surface 66 that descends from flat surface 64 toward first side edge 30 of base 14, first interlocking section 34 of first part 28 has a protrusion 68 that extends upward from flat surface 64 of first guide section 32. Second guide section 40 of second part 36 is complementary to first guide section 32, and second interlocking section 42 has a recess 70 that receives protrusion 68 of first interlocking section 34.
Alternatively, referring to FIG. 8, first guide section 32 of first part 28 has a flat surface 72 adjacent to first side edge 30 of base 14 and a tapered surface 74 that extends upward and away from flat surface 72 relative to first side edge 30 of base 14, and first interlocking section 34 of first part 28 has a recess 76 that is recessed from a top 78 of tapered surface 74.
Second guide section 40 of second part 36 is complementary to first guide section 32, and second interlocking section 42 has a protrusion 80 that is received by recess 76 of first interlocking section 34.
When engaged, the respective engagements may act as a labyrinth seal, or a mechanical seal that provides a tortuous path to help prevent leakage, through the corners of the culvert, thus ensuring that as much water as possible is diverted through the culvert, and does not leak into the surrounding area.
[0026] The angles of the various surfaces of the first and second parts of the engagements are selected such that the joints remain engaged and are biased toward engagement, but also permit some expansion when pressure is applied from within. For example, in the winter, water may freeze within culvert 12. The depicted engagements permit some movement to allow the freezing water to expand without damaging the culvert. As can be seen, there are surfaces at either end of the various bodies that are generally perpendicular to the respective body, or in other words, which are generally tangential to an arc that would be followed if the body were to pivot about its other end. These surfaces allow each body to slide outward in response to a force applied to the inner surface of culvert 12, while still being urged by gravity and the slope of that and other surfaces toward engagement.
[0027] The assembly of multi-sided culvert 10 will now be described.
Referring to FIG.
1, a base 14, is placed in an installation location. The installation location may be prepared by levelling or packing a material, such as road crush or gravel. Referring to FIG. 2 and 3, first and second side bodies 16 and 18 are then guided into place. As bodies 14, 16 and 18 may be quite heavy, they are preferably outfitted with lifting rings or apertures (not shown), such that they can be manipulated by a lifting crane, hoist, or other device. If bodies 14, 16 and 18 are cast from concrete, lifting cables or rings may be embedded as part of the casting process. As shown with first engagement 24, where base body 14 has a convex guide surface 32, it may be easier to slide surface toward the edge of base body 14, such that second guide section engages first guide section 32 and causes first body 16 to pivot and form first engagement 24.
As shown with second engagement 26, where base body 14 has a concave shape and second body 18 has a convex shape, the edge of second body 18 may be placed directly on first part 48 of base body 14, and the respective shapes will allow second engagement 26 to be engaged as second body 18 pivots about the bottom edge. It will be understood that the order of installation of first side body 16 and second side body 18 will depend on the type of top engagement 22 provided. For example, each side may be lowered simultaneously, or one may be lowered first and the second installed afterwards. Alternatively, it may be necessary to suspend one or both of first and second bodies 16 and 18 in a partially open position, and move them to a fully installed position either simultaneously, or in a coordinated manner, to ensure the respective engagement profiles are properly mated. Once the three bodies 14, 16, and 18 have been installed, the tapered surfaces of the connections will permit relative movement of the side panels while maintaining engagement, allowing for the multi-sided culvert to expand and contract, such as in response to freezing of water within the culvert.
[0028] Referring to FIG. 9 and FIG. 10, multi-sided culvert 10 may optionally have an engaging profile 82 along the edge of each of the side bodies 14, 16, and 18.
As depicted, engaging profile 82 is provided along the length of the engagements 22, 24, and 26, and has alternating protrusions and recesses that engage during installation of multi-sided culvert 10.
Engaging profile 82 may aid in the installation process by aligning the side bodies for forming connections. As well, engaging profile 82 may serve to prevent shifting of the side bodies along the engagements 22, 24, or 26. It will be understood that engaging profile 82 may take other forms that engage the respective edges and limit sliding movement of the side bodies, such as having different numbers of protrusions and recesses, having shaped profiles, or having a series of notches and recesses.
[0029] Base 14, side body 16, and side body 18 may be formed from any suitable material, as will be understood by those skilled in the art. For example, the three panels may be cast from cement, concrete, or any other material suitable for use as a culvert. In the configuration shown in FIG. 3, first side body 16 and second side body 18 have a top engagement 22 that also forms an interlocking connection. In other embodiments, such as the one in FIG. 5, after first side body 16 and second side body 18 are installed, top engagement
22 is formed with an additional connector, such as a bolt or clamp, although this is preferably a loose connection that still allows for some expansion, for the reasons as discussed above.
[0030] In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded.
