Assembly movable type anti-detonation device applied to round pier stud and construction method and replacing method of assembly movable type anti-detonation device

Abstract

The invention provides an assembly movable type anti-detonation device applied to a round pier stud and a construction method and a replacing method of the assembly movable type anti-detonation device. The anti-detonation device comprises a first protection layer, a second protection layer, a third protection layer and a fourth protection layer which are sequentially arranged from exterior to interior. The third protection layer and the fourth protection layer are of cylindrical structures, and the fourth protection layer is attached to the outer surface of the protected round pier stud. A bottom-layer ring-shaped steel plate is arranged at the bottom of the protected round pier stud, and the fourth protection layer is placed on the bottom-layer ring-shaped steel plate. The third protection layer is attached to the outer surface of the fourth protection layer. The second protection layer and the first protection layer are of segment type structures, every two adjacent segments are connected through a bearing, and a bearing is also arranged between the bottommost segment and the bottom-layer ring-shaped steel plate. All the bearings are arranged on the outer surface of the third protection layer in a sleeving manner. By means of the assembly movable type anti-detonation device applied to the round pier stud and the construction method and the replacing method of the assembly movable type anti-detonation device, bridge and building structure pier stud lateral damage and deformation generated under the small exploding and impacting effect can be reduced, and collapse of building and bridge structures caused by pier stud damage is avoided.

Description

technical field [0001] The invention belongs to the field of anti-explosion and anti-explosion of engineering structures, and in particular relates to an assembled movable anti-explosion device applied to a round pier column and a construction and replacement method thereof. Background technique [0002] Columns are the main stress-bearing components of bridges and building structures. They are often the first choice for terrorists to destroy and are easily threatened by accidental explosions. Once a column is damaged, it will not only affect the normal use of the structure, but even cause the structure or bridge to collapse, seriously threatening traffic. Transportation and people's lives are safe. Therefore, it is necessary to develop anti-blast protection devices for bridges and building structure piers to promote the effective improvement of structural anti-blast safety and comprehensive disaster prevention capabilities. Contents of the invention [0003] In view of th...
