Description

Technical Field

[0001] The utility model relates to the technical field of bridge widening, in particular to a widening device for municipal road bridges. Background Technique

[0002] The core process of the bridge widening project can be briefly described as follows: First, new bridge piers are built on one side of the existing bridge as supports. Subsequently, capping beams dedicated to widening are constructed on top of these piers. Then, precast beam slabs are precisely installed on the capping beams to ensure seamless connection with the old bridge, and the connection between the two is strengthened through wet joint technology. Next, the old bridge pavement is carefully treated, including milling and removing the old concrete layer, in preparation for the integration of the new and old bridges. Finally, a new cast-in-place concrete layer is uniformly poured to cover and tightly connect the new and old bridges, forming a stable and unified widened bridge structure.

[0003] When dealing with the gaps between bridge beam slabs, precise and efficient caulking operations are crucial. The currently commonly used method relies on manual operation, that is, the pre-mixed caulking material is manually poured into the gaps. However, this method not only makes it difficult to ensure the uniformity and compactness of caulking, but may also cause the gaps to be unfilled or have cavities due to human factors, thereby affecting the overall structural strength and durability of the bridge. In addition, the process of manually transporting and pouring the caulking material is cumbersome and time-consuming, greatly reducing the construction efficiency. Content of the Utility Model
