Description

Technical Field

[0001] The utility model belongs to the technical field of bridge engineering, and in particular relates to a traction-type bridge pier deviation correction device. Background Art

[0002] In recent years, with the rapid development of my country's social economy and transportation construction, my country's infrastructure such as highway engineering and bridge engineering has developed rapidly. Affected by geological disasters and deviations and errors in construction, bridges are prone to serious defects such as pier bending and offset. For example, factors such as heavy rainfall and damage to drainage channels cause the water content of the abutment fill to increase, causing the soil to slide toward the piers. The piers are subject to active soil pressure, which leads to bending and offset of the piers. In actual projects, defects such as bending and offset will reduce the bearing capacity of the piers, shorten the service life of the bridge, and even directly affect the normal use of the piers, endangering traffic safety. Therefore, timely and accurate bridge correction is a major issue that needs to be solved.

[0003] In actual engineering, the correction of the pier requires a large force, which is difficult to be applied by general engines or manpower. Traditional manual chain-down bridge correction often adopts the method of loading in batches, setting up multiple pull cables to add force in sequence, which has low construction efficiency, poor stability, and difficulty in accurately controlling the applied load. At the same time, it is difficult to achieve integrated correction and observation, which affects the construction precision control. At the same time, the existing correction construction is convenient to operate and simple in structure, but has poor controllability and low efficiency. When the force applied by different pull cables deviates greatly, it will cause torque to the pier, causing it to twist, which will cause secondary damage to the pier and pile foundation, affecting their lifespan.
