Assembled movable anti-explosion device applied to round pier column and its construction and replacement method

Abstract

The invention provides an assembled movable anti-explosion device applied to a round pier column and its construction and replacement method. The anti-explosion device includes a first protective layer, a second protective layer, and a third protective The third protective layer and the fourth protective layer, the third protective layer and the fourth protective layer are all cylindrical structures, the fourth protective layer is attached to the outer surface of the protected round pier, and the bottom of the protected round pier is provided with a bottom ring Steel plate, the fourth protective layer is placed on the bottom circular steel plate, the third protective layer is attached to the outer surface of the fourth protective layer, the second protective layer and the first protective layer are segmental structures, and two adjacent segments They are connected by bearings, and a bearing is also arranged between the lowermost segment and the bottom annular steel plate, and all the bearings are sleeved on the outer surface of the third protective layer. The invention reduces the lateral damage and deformation of bridges and building structure pier columns under the action of explosion and impact, and avoids the collapse of buildings and bridge structures caused by the damage of pier columns.

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...
