[0024] The present invention provides a square culvert assembly, which includes a first square culvert 10, a second square culvert 20, a rigid member 30 and a sealing strip, wherein the first square culvert 10 and the second square culvert 20 both have a frame-shaped connection surface, a steel bar portion protruding from the connection surface is arranged on the connection surface, the steel bar portion has a central through hole, the connection surface of the first square culvert 10 and the connection surface of the second square culvert 20 face each other and have a gap, so that the central through hole of the steel bar portion of the first square culvert 10 and the central through hole of the steel bar portion of the second square culvert 20 form an overlapping portion, the rigid member 30 is arranged through the overlapping portion, the sealing strip is arranged perpendicular to the connection surface along the outer edge and the inner edge of the connection surface, the sealing strip connects the first square culvert 10 and the second square culvert 20 so that the sealing strip and the connection surface jointly define a grouting chamber, and the grouting chamber is filled with a building injection material to fix the rigid member 30 in the grouting chamber. Among them, the first square culvert 10 and the second square culvert 20 provided in the present application can be made of reinforced concrete, and the sealing strip is also made of reinforced concrete.

[0025] like Figure 1 As shown, when the first square culvert 10 and the second square culvert 20 are aligned, the central through hole of the steel bar portion of the first square culvert 10 and the central through hole of the steel bar portion of the second square culvert 20 form an overlapping portion, and the rigid member 30 is arranged in the grouting chamber through the overlapping portion. The rigid member 30 is fixed in the grouting chamber formed between the first square culvert 10 and the second square culvert 20 by the building injection material, forming a rigid beam-type connection, thereby ensuring the connection strength between the first square culvert 10 and the second square culvert 20; and because it is sealed by the building injection material, the anti-seepage performance of the square culvert assembly is improved.

[0026] In the embodiment of the present application, the cross-section of the first square culvert 10 and the second square culvert 20 is rectangular, and the pipes of the first square culvert 10 and the second square culvert 20 are also rectangular, so the frame-shaped connecting surface includes four elongated splicing surfaces, and a rigid member 30 is arranged between each pair of opposite splicing surfaces of the first square culvert 10 and the second square culvert 20. The steel bar portion includes a plurality of steel bar rings 50 protruding from the connecting surface, and the steel bar rings 50 on the connecting surface of the first square culvert 10 and the steel bar rings 50 on the connecting surface of the second square culvert 20 are staggered. Specifically, the steel bar rings 50 on each splicing surface are arranged in sequence along the length direction of the splicing surface, preferably at equal intervals, and the steel bar rings 50 are arranged across the width of the splicing surface and the central through hole of the steel bar ring 50 on each splicing surface is perpendicular to the length direction of the splicing surface.

[0027] refer to Figure 2 In the structure shown, the sizes of the steel rings 50 on the connecting surface of the first square culvert 10 and the steel rings 50 on the connecting surface of the second square culvert 20 are exactly the same. When the first square culvert 10 and the second square culvert 20 are aligned, the steel rings 50 of the first square culvert 10 and the steel rings 50 of the second square culvert 20 overlap each other, so that the rigid member 30 can be set through the through holes of all the steel rings 50 between each pair of opposite splicing surfaces of the first square culvert 10 and the second square culvert 20.

[0028] Among them, Figure 2 In the structure shown, the rigid members 30 arranged in the horizontal direction are supported by the lower frame of the reinforcing steel ring 50, and the rigid members 30 arranged in the vertical direction can be supported on the rigid members 30 below them.

[0029] The rigid part 30 is made of I-beam, and the construction pouring material can be cement slurry or concrete. The structure of the I-beam can be better combined with cement slurry or fine stone concrete, self-compacting concrete, but the present application is not limited to this. The rigid part 30 can also be made of channel steel, square steel with holes, etc.

[0030] In order to pour building pouring material into the grouting chamber, a pouring hole is opened on the sealing strip, and the pouring hole is preferably opened on the portion of the sealing strip located on the top surface, so as to prevent the pouring material from flowing out of the grouting chamber.

[0031] It should be noted that the square culvert assembly provided in the present application is not limited to the form of a single-hole pipe. The first square culvert 10 and the second square culvert 20 can also be common double-hole, four-hole or other multi-hole square culverts. In the multi-hole square culvert, steel rings can be arranged on the connecting surface surrounding each hole to ensure that four rigid parts 30 are arranged around each hole, and then cement slurry or concrete can be poured.

[0032] The square culvert assembly of the present application can be spliced ​​with other single square culverts or square culvert assemblies with steel rings, see Figure 3 , Figure 4 and Figure 5 In the structure shown, the side of the first square culvert 10 facing away from the second square culvert 20 is also provided with a connecting surface and a steel ring 50 located on the connecting surface. The side of the second square culvert 20 facing away from the first square culvert 10 also has a connecting surface and a steel ring 50 located on the connecting surface to be connected to the third square culvert 60. Through this connection structure, the square culvert assembly provided in the present application can connect any number of square culverts.

[0033] A second aspect of the present application provides a method for assembling a square culvert, the method utilizing the above-mentioned square culvert assembly, the method comprising S1: aligning a connection surface of a first square culvert 10 with a connection surface of a second square culvert 20, so that a gap is formed between the connection surface of the first square culvert 10 and the connection surface of the second square culvert 20, so that a central through hole of a reinforcement portion of the first square culvert 10 and a central through hole of a reinforcement portion of the second square culvert 20 form an overlapping portion; S2: arranging a rigid member 30 through the overlapping portion; and S3: pouring a construction pouring material into a grouting chamber.

[0034] Specifically, refer to Figure 1 In the structure shown in the figure, the sealing strip includes a whole annular inner edge sealing plate 70 arranged on the inner edge of the connection surface and four outer edge sealing plates 40 arranged on the outer edge of the connection surface. The width of the inner edge sealing plate 70 and the outer edge sealing plate 40 is equal to the width of the gap between the first square culvert 10 and the second square culvert 20. Therefore, it is only necessary to set the sealing strip on one of the first square culvert 10 and the second square culvert 20. Figure 3 In the structure shown, the annular inner edge sealing plate 70 and the four outer edge sealing plates 40 are all arranged on the second square culvert 20 .

[0035] Among them, the length of the four outer edge sealing plates 40 is less than the side length of the square culvert, so that the four corners of the grouting chamber are not completely closed, so that the rigid parts 30 can be inserted from the four corners. The insertion of the rigid parts 30 should follow a certain order. First, the rigid parts 30 of the grouting chamber located at the bottom are inserted horizontally, and then the rigid parts 30 of the grouting chambers located on both sides are inserted from the two corners above in the vertical direction. Finally, the rigid parts 30 of the grouting chamber located at the top are inserted horizontally. Through this structure, the I-beams located on both sides can be supported on the I-beams located at the lower layer. In addition, in order to prevent the material from flowing out when pouring the material into the grouting chamber, especially from the two corners below, rubber pads can be inserted at the two corners below. The rubber pads can prevent the pouring material from flowing out and the rubber pads and the pouring material will eventually solidify together in the grouting chamber.

[0036] The square culvert assembly provided in the present application can be used as a pipe gallery channel, and cables and other pipelines are set in the channel formed by multiple square culverts. At the same time, since the present application uses cement slurry or fine stone concrete, self-compacting concrete to connect the square culverts, the channel formed by the multiple square culverts has good anti-seepage properties, so water can also flow directly in the channel, thereby serving as a water pipeline.

[0037] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications. Including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
