[0027] Embodiment:

[0028] Referring to the attached Figures 1-4 , a U-shaped combined concrete precast culvert mold in this embodiment includes a beam pedestal 1, a support frame 3, an outer frame 4, and an inner formwork 8. A stable casting mold is formed by combining various components, and each component is connected by bolts to ensure the stability and accuracy of the mold during the concrete casting process. After the concrete solidifies, the connection is released, and the outer frame 4 and the support frame 3 are removed to complete the preparation of the culvert.

[0029] Referring to the attached Figure 1 and Figure 2 , first connecting plates 2 are fixedly installed at the bottoms of the four sides of the beam pedestal 1, and legs 10 are fixedly installed at the four corners of the bottom of the beam pedestal 1. The legs 10 are fixedly installed on the ground, enhancing the overall stability and load-bearing capacity of the mold, and ensuring that the mold is not easily deformed or displaced during the concrete casting process.

[0030] Referring to the attached Figure 1 and Figure 3 , there are four groups of support frames 3, which are respectively arranged on the four sides of the beam pedestal 1. The support frame 3 includes a bottom plate 301, which is horizontally arranged. A second connecting plate 302 is fixedly installed at the bottom of the bottom plate 301. The first connecting plate 2 and the second connecting plate 302 arranged on the same side are arranged corresponding to each other left and right. Movable wheels 303 are fixedly installed at the four corners of the bottom of the bottom plate 301. An outer formwork 304 is fixedly installed on the top of the bottom plate 301. Among them, the bottom plate 301 and the outer formwork 304 are vertically arranged, and a reinforcing frame 305 is fixedly installed between the bottom plate 301 and the outer formwork 304. The reinforcing frame 305 enhances the connection strength between the bottom plate 301 and the outer formwork 304.

[0031] Referring to the attached Figure 1 and Figure 4, the outer frame 4 is arranged outside the four-side support frame 3, and lifting rings 11 are fixedly installed at the four corners of the top of the outer frame 4. During use, the operator uses a lifting device and the lifting rings 11 to lift and transport the outer frame 4. A receiving cushion block 5 is fixedly installed on the outer wall surface of the outer formwork 304. The receiving cushion block 5 realizes the limit of the outer frame 4. A third connecting plate 6 is fixedly installed on the receiving cushion block 5, and a fourth connecting plate 7 is fixedly installed on the outer frame 4. The third connecting plate 6 and the fourth connecting plate 7 arranged on the same side correspond up and down.

[0032] Refer to the appendix Figures 1-4 , the inner formwork 8 is arranged above the beam pedestal 1. Connecting pieces 9 are fixedly installed at the four corners of the top of the inner formwork 8. The connecting pieces 9 are of an inverted U-shaped structure, and the connecting pieces 9 are fixedly connected to the top of the outer frame 4. Through the connecting pieces 9, the inner formwork 8 and the outer frame 4 move synchronously.

[0033] Refer to the appendix Figure 4 , the inner formwork 8 is of a U-shaped structure, and the length of the inner formwork 8 is less than the length of the outer formwork 304. The width of the inner formwork 8 is numerically equal to the length of the outer formwork 304. The height of the outer formwork 304 is less than the height of the outer formwork 304. After the inner formwork 8 is placed, a pouring cavity is formed between the inner formwork 8, the beam pedestal 1 and the outer formworks 304 on the four sides. Concrete is poured into this cavity for preparing the box culvert.

[0034] When this U-shaped combined concrete precast box culvert mold is in use, the four support frames 3 are respectively moved to the four sides of the beam pedestal 1 so that they are respectively close to the four sides of the beam pedestal 1. Then, bolts are used to connect the first connecting plate 2 and the second connecting plate 302 on the same side, realizing the preliminary connection of the four support frames 3 and the beam pedestal 1. Subsequently, a lifting device is used to lift and transport the outer frame 4, so that the outer frame 4 moves downward along the outer formworks 304 on the four sides. The receiving cushion block 5 on the outer formwork 304 is used to limit the outer frame 4, and bolts are used to connect the third connecting plate 6 and the fourth connecting plate 7 on the same side. When the bottom of the outer frame 4 contacts the receiving cushion block 5, the top of the inner formwork 8 and the tops of the outer formworks 304 on the four sides are on the same horizontal plane. At this time, concrete is poured into the cavity for preparing the box culvert. After the box culvert is prepared, first disconnect the connection between the third connecting plate 6 and the fourth connecting plate 7, remove the outer frame 4, and then disconnect the connection between the first connecting plate 2 and the second connecting plate 302, and remove the four support frames 3, then the formed box culvert can be transported.

[0035] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
