Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a supporting structure for municipal road and bridge construction. Background Art

[0002] Road and bridge construction is the core project in municipal engineering. This link is generally carried out outdoors. Therefore, it is not only affected by the environment, but also the ground structures, route design and underground pipelines are all key points that need to be paid attention to during construction. In real life, the construction of roads and bridges has greatly improved the convenience of transportation. However, in the process of road and bridge construction, it is generally necessary to use support devices to provide corresponding support.

[0003] The utility model with the existing authorization announcement number CN202120111979.5 discloses a support device for road and bridge construction. The above-mentioned technical scheme is adopted to fix the position of the device body by a support rod and a docking rod in cooperation with a second connecting seat, a fixing seat and a fixing screw, thereby improving the support stability of the device. The relative position relationship of the first top plate, the second top plate and the third top plate can be adjusted by a first cylinder, a second cylinder and a second cylinder in cooperation with a first telescopic rod, a second telescopic rod, a third telescopic rod, a first connecting seat and a fixing rod, thereby solving the problem that the existing support device is only supported by a single flat plate and has low support flexibility. However, the above-mentioned technical scheme, when in use, has a large number of electric mechanical parts and a relatively large structural volume, and requires the staff to fix the fixing bolts directly to the ground to ensure the overall stability of the device. It is not only time-consuming and labor-intensive, but also has poor stability when only fixed to the ground by fixing bolts. Moreover, when moving, multiple staff members are required to move the support device, which is not convenient to move, resulting in relatively low flexibility and certain limitations.

[0004] Therefore, those skilled in the art provide a support structure for municipal road and bridge construction to solve the problems raised in the above background technology. Utility Model Content
