[0002] As is known, the expansion joint construction of bridges is generally carried out at the last part of the bridge, after the auxiliary systems of the bridge deck and the asphalt surface are laid, and before the bridge deck expansion joints are opened to traffic. The installation of expansion joints will use a bridge cutting machine, also known as a gasoline pavement cutting machine, which uses a thickened frame and a diamond saw blade, and is mainly used to cut the expansion joints of concrete pavements.

[0003] The specific steps for bridge expansion joints are to first cut the asphalt pavement. The cutting area is directly above the abutment, where the expansion joint between the upper beam and the back of the abutment is located. Before cutting, the asphalt pavement is marked, and then the pavement cutting machine is pushed to cut the asphalt pavement along the marked line. During the cutting process, the straightness of the cutting line should be ensured, the forward speed should be uniform and the process should be smooth, and the cutting depth should be controlled when cutting.

[0004] During the process of cutting the expansion joint of the bridge, the operator pushes the cutting machine to cut the road surface along the marked line. This process has high requirements on the operator's operation. The cutting machine may slightly deviate from the marked line when pushed, resulting in the cutting line not being straight, affecting the subsequent installation and construction.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-4 The bridge cutting machine is used to solve the problem that during the removal process of the bridge expansion joint, the operator pushes the cutting machine to cut the road surface along the marked line. This process has high requirements on the operator's operation. When pushing, the cutting machine may slightly deviate from the marked line, resulting in the cutting line not being straight, affecting the subsequent installation and construction.

[0023] The technical solution further proposed by the present invention includes a seam cutter 2 and also includes: a positioning plate 3, which is arranged on the bridge 1, and a placement groove 3.2 is opened on the positioning plate 3, and the placement groove 3.2 is opened along the length direction of the positioning plate 3. A positioning seat 4 is arranged on the seam cutter 2, and a positioning rod 4.2 adapted to the guide groove 3.3 is arranged on the positioning seat 4. Specifically, when cutting the seam of the bridge 1, the positioning plate 3 is first installed on the bridge deck of the bridge 1, and then the positioning rod 4.2 on the tail of the seam cutter 2 is installed in the guide groove 3.3 of the positioning plate 3 through the placement groove 3.2. When the operator pushes the seam cutter 2 to cut the bridge 1 along the marking line, the cooperation between the guide groove 3.3 and the positioning rod 4.2 plays a guiding and limiting role for the seam cutter 2, thereby improving the stability of the seam cutter 2 when being pushed, making the cutting straighter, and weakening or even avoiding the problem in the prior art that the cutting machine slightly deviates from the marking line when being pushed, resulting in the cutting line being not straight, thereby affecting the subsequent installation and construction.

[0024] In this embodiment, the end of the positioning plate 3 is matched with the bridge surface 1.2 on the bridge 1, and the two are connected at 90 degrees. Figure 2 As shown in the state, it is convenient for the positioning plate 3 to be clamped and installed on the bridge 1. In order to improve the stability of the positioning plate 3 after installation, the positioning plate 3 and the bridge 1 can be threadedly connected and fixed by threaded fasteners through the through holes 3.1 on the positioning plate 3; Figure 1 As shown in the state, the positioning plate 3 is used to limit and guide the seam cutter 2 to improve its stability when it is pushed, and the specific pushing of the seam cutter 2 for cutting is a prior art and is not repeated; the number of the placement grooves 3.2 is specifically two, which are relatively opened on the positioning plate 3, and the guide groove 3.3 is opened between the two placement grooves 3.2, such as Figure 1 and Figure 2 Status shown.
