[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] like Figure 1 As shown, the assembled culvert support structure disclosed in the present application includes a first culvert body 1. In the present embodiment, the first culvert body 1 is square, and its two side edges located in the first direction (indicated by the height direction) and the top side edges connecting the two side edges and located in the second direction (indicated by the width direction) can be an equilateral square with equal side lengths, or a rectangle with a side height greater than a fixed side width, or a rectangle with a top side width greater than the side height, or a trapezoidal shape obtained by slightly deforming the square state.

[0033] Two support units 2 are erected opposite to each other on the left and right sides of the first culvert body 1 of the above-described shape. The two support units 2 support the two side edges of the first culvert body 1 in the first direction to reinforce the two side edges, wherein the top ends of the two support units 2 are deformed to be located in the second direction and reinforce the top side edges.

[0034] In this embodiment, the width of the top side is greater than the height of the left and right sides, and because most of the support unit 2 is located on the side in the first direction and only a small part is located on the top side in the second direction, this makes it impossible to provide greater support strength to the top side. Therefore, a connecting unit 3 is also provided on the top side in the second direction, and the connecting unit 3 is respectively connected to the top ends of the two support units 2, and under this connection, the connecting unit 3 is limited on the top side, so that the connecting unit 3 is combined with the ends of the two support units 2 to increase the support strength to the fixed side.

[0035] like Figure 1 As shown, the support unit 2 combined with the connecting unit 3 can be connected to form a cross-sectional shape that fits the first culvert body 1, that is, occupying a portion of the space on the inner surface of the first culvert body 1, thereby minimizing the occupation of the aisle in the first culvert body 1 as much as possible, thereby reinforcing the culvert body 1 while not affecting the passage of people and vehicles.

[0036] The structures of various parts of the present disclosure, such as the supporting unit 2 and the connecting unit 3, will be described in detail as follows.

[0037] like Figure 1 As shown, the support unit 2 includes a first support portion 21, a second support portion 22 in a first direction, and a third support portion 23 in a second direction. The support portions 21 are connected in sequence or mutually through a plurality of support rod body parts. The support rod bodies are specifically configured as: a first support rod body 24 rotatably connected between the first support portion 21 and the third support portion 23; a second support rod body 25 rotatably connected between the first support rod body 24 and the second support portion 22; and a third support rod body 26 rotatably connected between the second support portion 22 and the third support portion 23. As above, a support unit 2 located on all left and right sides and a partial top side is constructed.

[0038] Furthermore, the first supporting portion 21 is located at the starting point of the first direction, that is, the two side portions of the aisle in the culvert, and specifically includes an abutment plate 5. The abutment plate 5 is in an overall vertical shape in this embodiment, and is fittedly arranged on the left and right sides of the first culvert body 2. Positioning holes are opened on the abutment plate 5, for example, at the four corners, and holes are punched at the portions on the left and right sides corresponding to the positioning holes, so that the abutment plate 5 is fixed to the left and right sides by fasteners such as expansion bolts.

[0039] It also includes a U-shaped seat 6 that can slide on the abutment plate 5. Specifically, the contact portion of the U-shaped seat 6 with the abutment plate 5 is in a semi-wrapped state and is located on the abutment plate 5, so that the U-shaped seat 6 can be moved to slide on the abutment plate 5, and corresponding limiting holes are provided on the U-shaped seat 6 and the abutment plate 5 (not shown in the figure). When the sliding U-shaped seat 6 moves on the abutment plate 5, the limiting holes on the U-shaped seat 6 are aligned with one of the limiting holes on the abutment plate 5, and the U-shaped seat 6 is fixed to the abutment plate 5 by using a bolt assembly to pass through the corresponding limiting hole group. The height of the U-shaped seat 6 on the abutment plate 5 can be changed through such coordinated fixation, and the U-shaped seat 6 is used to be connected to the first support rod body 24, so that when the height of the U-shaped seat 6 on the abutment plate 5 is adjusted, the initial height of the first support rod body 24 is adjusted.

[0040] Furthermore, the second supporting portion 22 also includes an abutment plate 5. The connection between the abutment plate 5 and the side of the first culvert body 1 refers to the above-mentioned description of the connection between the abutment plate 5 and the side of the first supporting portion 21, and the description is not repeated here. However, it should be noted that the abutment plate 5 is not directly connected to the side during installation, but is selectively connected according to the height of the side, that is, the position where the abutment plate 5 is connected to the side is roughly located in the middle of the side in the first direction.

[0041] The second supporting portion 22 further includes a U-shaped seat 6 integrally connected to the abutting plate 5, for example, by welding, and the U-shaped seat 6 is used to connect the second support rod body 25 and the third support rod body 26.

[0042] The third supporting portion 22 also includes an abutment plate 5 , which is used to be connected to the top side edge of the first culvert body 1 in the second direction. For the specific shape and connection of the top side edge, refer to the above description of other abutment plates 5 .

[0043] The third supporting portion 22 also includes an articulated seat 7 rotatably connected to the abutment plate 5 (for example, by means of a rivet shaft passing through a connecting hole), the articulated seat 7 having three articulation points in a first direction, a U-shaped seat 6 connected at the top articulation point, and the height of the articulated seat 7 is changed to allow the connected abutment plate 5 to contact the top side.

[0044] In summary, on the basis of the first supporting part 21, the second supporting part 22, and the third supporting part 23, the first support rod body 24, the second support rod body 25 and the third support rod body 26 in this embodiment are preferably all composed of a telescopic rod 8 and a mother rod 9 sleeved outside the telescopic rod 8, and a limiting structure is provided between the telescopic rod 8 and the mother rod 9. The limiting structure is configured to limit the length of the telescopic rod 8 extending out of the mother rod 9. The limiting structure includes a plurality of positioning holes opened on the telescopic rod 8 and the mother rod 9. The positioning holes of any group of the telescopic rod 8 and the mother rod 9 are aligned according to the length required for fixing, and are fixed through the bolt assembly to limit the length of the adjusted support rod.

[0045] Specifically, the mother rod 9 of the first support rod body 24 is rotatably connected to the U-shaped seat 6 of the first supporting part 21, and the telescopic rod 8 is rotatably connected to the third hinge point at the bottom end of the hinge seat 7 of the third supporting part 23. The length of the telescopic rod 8 extending on the mother rod 9 is adjusted by the limiting structure, and combined with the height of the U-shaped seat 6 on the mother rod 9 on the abutment plate 5 of the first supporting part 21, the height of the hinge seat 7 connected to the end of the telescopic rod 8 in the first culvert body 1 is changed, so that the hinge seat 7 supports the abutment plate 5 connected thereto to contact the top side of the first culvert body 1, specifically, contact the top side portion close to the end portion.

[0046] In addition, a U-shaped seat 6 is integrally connected to the mother rod 9 of the first support rod body 24, and the U-shaped seat 6 is used to connect the second support rod body 25 in combination with the U-shaped seat 6 on the second support part 22. Specifically, the mother rod 9 of the second support rod body 25 is rotatably connected to the mother rod 9 of the first support rod body 24, and the telescopic rod 8 is rotatably connected to the U-shaped seat 6 of the second support part 22.

[0047] And the mother rod 9 of the third support rod body 26 is also connected to the U-shaped seat 6 of the second support part 22, and the telescopic rod 8 is rotatably connected to the hinge seat 7 of the third support part 23. By adjusting the length of the second support rod body 25 and the third support rod body 26 to support the second support part 22 to be roughly located in the middle of the side of the first culvert body 1 in the first direction, and then combining with adjusting the length of the fourth support rod body 31 to support the third support part 23 to be located on the top side of the first culvert body 1 in the second direction.

[0048] Furthermore, the connection unit 3 connected between the two support units 2 includes:

[0049] There is at least one fourth support rod body 31 connected between the hinge seats 7 of the third supporting parts 23 of the two support units 2. The number is not limited to one. Two are shown in the figure. This is determined according to the actual pressure borne by the top side. It can also be three or more.

[0050] And two fourth supporting parts 32 are slidably connected between the fourth support rod bodies 31. The fourth supporting parts 32 are combined with the third supporting parts 23 of the two supporting units 2 located on the top side in the second direction to provide strong support for the top side.

[0051] Specifically, the structure of the fourth support rod body 31 in this embodiment is consistent with the structure of other support rod bodies 31, and no further description is given here. The overall length can also be adjusted according to actual needs so that it can be connected between two support units 2.

[0052] Specifically, the two fourth supporting parts 32 also include an abutment plate 5 and a support seat 10 rotatably connected to the abutment plate 5. The support seat 10 is hollow inside and penetrates in the second direction, and is provided with a wrapped and sliding limit groove inside. The number of the limit grooves is consistent with the number of the fourth support rod bodies 31. For example, when there are two fourth support rod bodies 31, in order to allow the support seat 10 to slide on the fourth support rod body 31, the number of the limit grooves needs to be two.

[0053] Furthermore, the limiting groove is composed of two baffles 11 spaced along the first direction in the support seat 10, and because the fourth support rod body 31 is composed of the telescopic rod 8 and the mother rod 9, the two fourth supporting parts 32 need to slide outside the telescopic rod 8 and the mother rod 9 sections respectively, and the telescopic rod 8 and the mother rod 9 have different widths, which leads to different specifications of the limiting grooves in the two support seats 10, which are defined as: the limiting groove in the support seat 10 located on the telescopic rod 8 section is adapted to the telescopic rod 8 section, and the limiting groove in the support seat 10 located on the mother rod 9 section is adapted to the mother rod 9 section, thereby limiting the sliding of the two support seats 10 on their respective sections, so that the spacing between the two third supporting parts 23 and the two fourth supporting parts 23 is equidistant, thereby evenly bearing the pressure brought by the top side of the first culvert body 1.

[0054] like Figure 2 As shown, the assembled culvert support structure disclosed in the present application includes a second culvert body 4. In this embodiment, the second culvert body 4 is in an arch shape, for example, half the circumference of a circle or any arch-shaped circumference between more than half and four-fifths.

[0055] Two support units 2 are installed in the second culvert body 1 of the above-mentioned shape. The two support units 2 are arranged in a first direction (indicated by Figure 2 It should be noted that the support unit 2 has the same structure as the support unit 2 of the previous embodiment, and will not be described again here. Please refer to the previous embodiment. The difference is that the three supporting parts of the support unit 2 in this embodiment are all located on the first direction "A" section of the second culvert body 1.

[0056] The connecting unit 3 connecting the two support units 2 and located in the second direction "B" section is different. Compared with the connecting unit 3 of the previous embodiment, the connecting unit 3 includes a fifth strut body 33 rotatably connected to the two support units 2. The number of the fifth strut bodies 33 connected to the support units 2 can be one, two, three or more, and its structure is consistent with other strut body structures.

[0057] The fifth support rod body 33 is rotatably connected to the fourth support portion 32 at one end away from the support unit 2. Therefore, in the present embodiment, the fourth support portion 32 cannot slide, and the fourth support rod body 31 is fixed between the two fourth support portions 32. By adding the fifth support rod body 33 and adjusting the lengths of other support rod bodies, the disclosed support structure is roughly arched and erected in the second culvert body 4. In order to fit on the inner wall of the second culvert body 4, the contact surface of the abutment plate 5 on each support portion is arched in the present embodiment, and is vertical relative to one side of the contact surface.

[0058] In this embodiment, after adjustment, the length of the fourth strut body 31 plus the fifth strut body 32 is greater than the distance between the third supporting parts 23 of the two support units 2, so that the support unit 2 limits the second direction of the second culvert body 4 of the connecting unit 3.

[0059] like Figure 3 As shown, it is applicable to the support rod body in the embodiment described above, that is, another structure of the support rod body, which includes two telescopic rods 8 and a mother rod 9 connected between the two telescopic rods 8 by a limiting structure. The limiting structure is: limiting holes opened on the two telescopic rods 8 and the mother rod 9, and a bolt assembly. Specifically, by aligning one of the locating holes of the two telescopic rods 8 with a designated locating hole of the mother rod 9, and then fixing the bolt assembly through the aligned locating hole, the overall length of the support rod body can be adjusted.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
