Description

Technical Field

[0002] The construction of bridge piers is one of the key links in bridge construction, which directly affects the stability and safety of the bridge. The construction methods are different according to the height of the pier. Variable-section hollow thin-walled piers are a widely used structural form in bridge engineering, especially suitable for high pier design, to adapt to different force requirements and save materials.

At the construction site, the piers of the bridge are more than 100 meters long, and the abutments need to simultaneously construct equal-section hollow thin-walled piers and variable-section hollow thin-walled piers. The cross-sections of the piers in this project are all rectangular. During the construction of the variable-section hollow thin-walled piers, the size of the interface gradually decreases according to the change in construction height. The use of flaps of equal length cannot meet the needs of construction. The factory prefabricates flaps of different lengths, which are inconvenient to install and disassemble, and have high manufacturing costs. By moving the slide plates 5, the length of the flaps 3 can be expanded, thereby meeting the needs of construction within a certain range, and can be reused later. It can be applied in the construction process of hollow thin-walled piers with equal cross-sections. Since there is a certain angle between the flap 3 and the pier column, there is a large gap between the flaps at the corners, and the sealing component 4 can effectively fill the gap to ensure the overall installation effect while avoiding falling objects from high altitudes. It is easy to use and has high safety. The sealing strip is made of flexible rubber material and can fit well on the side wall of the pier column, ensuring the overall blocking effect and avoiding the slurry of the cast-in-place pier column section on the upper side from flowing through the gap between the flap 3 and the side wall of the pier column to the completed pier column at the lower part, causing pollution to the pier column.
