Description

Technical Field

[0001] The present invention relates to the technical field of devices and methods for removing inclined bridge piers, and in particular to a method and device for removing inclined bridge piers in complex urban areas. Background Art

[0002] my country's urbanization is developing rapidly. The bridges built in the early days cannot meet the needs of the rapid development of urban transportation in terms of load level, traffic function, safe operation and bridge aesthetics. The rapid development of my country's economy and society and the continuous improvement of its comprehensive national strength have accelerated the pace of urbanization in my country. Some buildings and structures built in the early days can no longer meet the current social needs in terms of use function, load level, operational safety and urban aesthetics. The cost of repairing and reinforcing old buildings and structures is too high, and they are facing the fate of being eliminated. Under this background, the technology of bridge demolition faces challenges.

[0003] In recent years, with the needs of urban construction, the need for environmentally friendly bridge demolition has greatly increased under complex urban conditions. Since the bridge is demolished under complex urban conditions, in order to ensure the safety of people and property around the demolished bridge, dangerous blasting methods cannot be used to demolish various parts of the bridge.

[0004] The traditional demolition method is to set up scaffolding around the piers, then tie up the piers, and finally use the cutting and lifting method to remove the piers. However, this demolition method is very prone to safety accidents such as slipping and falling during the cutting and lifting processes, posing a great safety hazard. Summary of the invention

[0005] In view of the above problems, the present invention aims to solve the above problems. One object of the present invention is to provide a method and a device for removing complex urban inclined bridge piers to solve the above problems.

[0006] A complex urban inclined bridge pier removal method and removal device may include:

[0007] S1. Drilling: Drill installation holes evenly around the inclined bridge pier;

[0008] S2. Install the lifting eye: The connecting screw thread passes through the lifting ear of the lifting eye and extends into the installation hole to form the lifting eye and the inclined bridge pier into a whole;
