[0025] The features and performance of the precast culvert connection structure and precast culvert device of this application will be further described in detail below with reference to the embodiments.

[0026] Example 1 like Figure 1As shown in the figure, this application provides a prefabricated culvert connection structure, which includes two coaxially spaced culverts 100, an annular rubber plate 300, an annular concrete wrapping layer 110, thirty-two I-beams 120 embedded in the concrete wrapping layer 110, two annular inner waterstop steel plates 130 embedded in the concrete wrapping layer 110, annular outer waterstop steel plates 140 embedded in the concrete wrapping layer 110, and annular connecting steel plates 150 embedded in the concrete wrapping layer 110. The outer walls at both ends of the rubber plate 300 are connected to the inner walls of the two culverts 100 by spaced connecting bolts 220. The inner walls at both ends and the middle of the concrete wrapping layer 110 are connected to the outer walls at the ends of the two culverts 100 and the rubber plate 300, respectively. The middle outer wall is connected; the outer walls of the two culverts 100 are respectively fitted with annular templates 190 connected to both ends of the concrete wrapping layer 110. The end faces of the two culverts 100 are respectively connected to sixteen circumferentially spaced I-beams 120. The sixteen I-beams 120 connected to the end faces of the two culverts 100 are coaxially arranged and respectively connected to both sides of the annular connecting steel plate 150. Two inner water-stop steel plates 130 are respectively connected to the end faces of the two culverts 100 and located inside the corresponding I-beams 120. Two outer water-stop steel plates 140 are respectively connected to the end faces of the two culverts 100 and located outside the corresponding I-beams 120. The ends of the inner water-stop steel plates 130 and the outer water-stop steel plates 140 away from the corresponding culverts 100 are bent toward the direction closer to the corresponding I-beams 120.

[0027] Five reinforcing bars 160 are embedded in the concrete wrapping layer 110. The reinforcing bars 160 are located below the two culverts 100. The two ends of the reinforcing bars 160 are connected to the fixing bars 180 by connecting bars 170. The fixing bars 180 are connected to the bottom of the culvert 100. The connecting bars 170 pass through the annular formwork 190.

[0028] In the manufacturing process of the prefabricated pipe culvert connection structure provided in this application embodiment, two pipe culverts 100 are first fixedly arranged coaxially at intervals. Then, two annular inner waterstop steel plates 130 are respectively connected to the inner side of the end faces of the two pipe culverts 100 at their adjacent ends. Thirty-two I-beams 120 are respectively arranged circumferentially at intervals and connected to the end faces of the two pipe culverts 100 at their adjacent ends, so that the sixteen I-beams 120 connecting the end faces of the two pipe culverts 100 are coaxially arranged in a one-to-one correspondence. The inner water-stop steel plates 130 are located inside each I-beam 120. An annular connecting steel plate 150 is placed between each I-beam 120. The I-beams 120 connecting the two culverts 100 are welded to both sides of the annular connecting steel plate 150. Two outer water-stop steel plates 140 are connected to the end faces of the two culverts 100, so that the two outer water-stop steel plates 140 are located outside the corresponding I-beams 120. An annular rubber plate 300 is placed between the inner walls of the two culverts 100, and... Do not use connecting bolts 220 to connect the two ends of the rubber plate 300 to the inner walls of the adjacent ends of the two culverts 100 respectively. Fix the two annular templates 190 to the outer walls of the two culverts 100 respectively. Arrange each reinforcing steel bar 160 below between the two culverts 100, and weld the connecting steel bars 170 through the two annular templates 190 to the two ends of the reinforcing steel bars 160 respectively. Connect the fixing steel bars 180 welded to each connecting steel bar 170 to the bottom of the two culverts 100 respectively. Connect the annular outer template between the two annular templates 190. Pour concrete into the space formed by the outer template, the two annular templates 190, the outer walls of the two culverts 100 and the outer wall of the rubber plate 300 to obtain the encasing concrete encasing layer 110, thereby completing the manufacturing of the precast culvert connection structure. After the concrete encasing layer 110 has cured, the outer template, the annular template 190 can be removed and the supporting column 210 can be removed. Then remove the rubber plate 300 and the precast culvert connection structure can be transported for construction.

[0029] The prefabricated pipe culvert connection structure provided in this application embodiment connects circumferentially spaced and corresponding H-beams 120 to the end faces of two pipe culverts 100 and connects each H-beam 120 with connecting steel plates 150. This structure has the advantages of simple construction, low requirements for connection accuracy, high connection strength, and good connection stability. Simultaneously, inner water-stop steel plates 130 and outer water-stop steel plates 140, located inside and outside the H-beams 120 respectively, are connected to the end faces of the two pipe culverts 100. The ends of the inner water-stop steel plates 130 and outer water-stop steel plates 140 furthest from the corresponding pipe culvert 100 are respectively oriented towards the corresponding H-beam 120. A 0-direction bend can form a double-layer water-stop structure, thereby maximizing the solution to the leakage problem between the two culverts 100; a reinforcing steel bar 160 is set below the two culverts 100, and the reinforcing steel bar 160 is connected to the fixed steel bar 180 connected to the bottom of the culvert 100 through the connecting steel bar 170, which can form a reinforced concrete pad at the bottom of the connection part of the two culverts 100, ensuring that the foundation is integrated and there will be no uneven settlement; an annular rubber plate 300 is set inside the connection part of the two culverts 100 as an inner formwork to assist in the construction of the concrete wrapping layer 110, and the rubber plate 300 can be recycled.

[0030] In other alternative embodiments, the number of I-beams 120 can be adjusted as needed, and can be up to thirty-two or more.

[0031] In other alternative embodiments, the number of reinforcing bars 160 can be adjusted as needed, and can be one, two, three, four or more.

[0032] Example 2 like Figure 2 As shown, this application embodiment provides a prefabricated pipe culvert connection structure, which is roughly the same as the prefabricated pipe culvert connection structure provided in Embodiment 1. The difference is that in this embodiment, the pipe culvert 100 is provided with a support column 210 that can move along its axial direction, and the outer wall of the support column 210 abuts against the inner wall of the rubber plate 300; the concrete wrapping layer 110 is embedded with an annular steel mesh 200 sleeved on the outside of the two pipe culverts 100, and the two ends of the steel mesh 200 are respectively connected to two annular templates 190.

[0033] The precast culvert connection structure provided in this application embodiment inserts a support column 210 into the culvert 100 between the poured concrete wrapping layers 110, and makes the outer wall of the support column 210 press against the inner wall of the rubber plate 300. This can prevent the concrete from collapsing the rubber plate 300 and forming bulges when the concrete wrapping layer 110 is poured, ensuring the stable pouring of the concrete wrapping layer 110. After the concrete wrapping layer 110 is poured, the support column 210 can be pulled out and the rubber plate 300 can be disassembled to achieve the reuse of the equipment.

[0034] Between the poured concrete wrapping layer 110, annular steel mesh 200 is fitted onto the outer side of the ends of the two culverts 100, and the two ends of the steel mesh 200 are connected to the two annular templates 190 respectively, so that the poured concrete wrapping layer 110 wraps the steel mesh 200. The steel mesh 200 embedded in the concrete wrapping layer 110 can improve its overall structural strength.

[0035] This application also provides a prefabricated culvert device, which includes the above-described prefabricated culvert connection structure.

The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
