[0023] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0024] See also Figures 1 to 4 This embodiment provides a temporary support structure for a pipeline across a river, including a first I-beam 1 and a support frame. Two sets of support frames are arranged at intervals, and are specifically installed in the river channel. A plurality of first I-beams 1 are overlapped at intervals above the two sets of support frames to serve as crossbeams of the two sets of support frames. Figure 2 , multiple pipelines 2 are arranged above the first I-beam 1; second I-beams 3 are respectively installed and fixed on both sides of each pipeline 2, and the second I-beams 3 can limit and fix the arrangement of the pipelines 2, and can also constrain the regular arrangement of the pipelines of each pipeline 2. The pipelines 2 include weak current channels, water supply pipelines, gas pipelines and / or power channels.

[0025] like Figure 2 , Figure 3 and Figure 4 The support frame includes a steel pipe pile 4 and a channel steel 5. A plurality of steel pipe piles 4 are arranged at intervals along the same straight line and are arranged in the river channel. The lower part of the steel pipe pile 4 is used to be inserted and fixed in the riverbed of the river channel. An inner stiffening plate 6 is arranged on the inner side of each steel pipe pile 4, which can be fixed by welding. An outer stiffening plate 7 is arranged on the outer side of each corresponding steel pipe pile 4, which can also be fixed by welding. The two ends of the channel steel 5 are respectively used to overlap the revetments 8 on both sides of the river channel, so that the steel pipe pile 4 reduces part of the gravity of the channel steel 5 and the first I-beam 1. The waist part of the channel steel 5 is sequentially arranged above the inner stiffening plate 6 of each steel pipe pile 4, and the waist part of the channel steel 5 is fixedly connected to the steel pipe pile 4 and the inner stiffening plate 6, respectively, and can be fixed by welding.

[0026] like Figure 3 The upper end faces of the channel steel 5 and the external stiffening plate 7 are flush with the upper end faces of the multiple steel pipe piles 4. This arrangement can avoid deliberately setting the placement position of the first I-beam 1, and can be arranged arbitrarily above the two groups of support frames. The channel steel 5 and the external stiffening plate 7 can both assist the steel pipe piles 4 in improving the support area and stability of the first I-beam 1, and the internal stiffening plate 6 strengthens the strength of the connection between the channel steel 5 and the steel pipe piles 4, thereby ensuring the stability of the overall support connection. The internal stiffening plate 6 and the external stiffening plate 7 are both inverted trapezoidal structures, which can enhance the overall stability of the support frame. The thickness of the selected stiffening plate and the external stiffening plate 7 can be selected to be 10 to 12 mm.

[0027] In some embodiments, the first I-beam 1 is a 32a I-beam, and the second I-beam 3 is a 20a I-beam. A single first I-beam 1 is selected to have a length ranging from 5.5 to 6m and is overlapped on two sets of support frames, and the spacing between two adjacent first I-beams 1 is set to be 2 to 2.5m.

[0028] Further, in some embodiments, the distance between the center lines of two corresponding steel pipe piles 4 in two groups of support frames is 3.9m, and the length of the overlapped first I-beam 1 is 5.5m. The distance between the center lines of two adjacent steel pipe piles 4 in the same group of support frames is 4m. This arrangement can ensure the stability of the support and avoid excessive waste of temporary support construction.

[0029] In some embodiments, the selected steel pipe pile 4 has an outer diameter of 273 mm, a wall thickness of 8 to 10 mm, and a pile length of 12 to 14 m.
