[0016] The utility model is described in detail below with reference to the drawings and examples.

[0017] As Figure 1 , Figure 2 , Figure 3 The utility model discloses a roadbed supporting device for road and bridge construction, which is used for supporting and fixing the roadbed and is specifically used for stably supporting the newly widened roadbed. The device comprises a plurality of supporting piles 3 arranged side by side and symmetrically. Each supporting pile 3 is composed of a top seat 4 and a column 7. The top seat 4 is installed at the top of the column 7. The supporting device 2 is made of stainless steel. One side of the column 7 is provided with an opening. The concrete filler is poured into the column 7 through the opening. After the concrete filler is solidified, the opening is sealed with a sealing cover 71 to form a prefabricated column 7. During use, the column 7 is vertically arranged. After the top seat 4 is fixed on the column 7, the widened part 1 of the roadbed is laid above the top seat 4.

[0018] As Figure 2 , Figure 3 The top seat 4 is composed of a bearing plate 5 and a fastener 6. The lower part of the bearing plate 5 is further provided with an integrated reinforcing plate 51. A plurality of accommodating grooves are formed on the side of the reinforcing plate 51 facing the fastener 6. A plurality of fasteners 6 are symmetrically arranged. Each fastener 6 corresponds to one accommodating groove. The fastener 6 is welded and installed in the accommodating groove. The fastener 6 is provided with at least four fasteners 6. Each fastener 6 comprises a connecting block 61 and a connecting rod 62. The back surfaces of the four fasteners 6 abut against each other.
