Embodiment 1

[0033] Referring to Fig. 1 and Fig. 2, a column anti-collision protection body includes a protective body 2 ringed outside the column body 1 and a fiber cloth 4 ringed outside the protective body 2, the protective body 2 is in rubber concrete Steel mesh rubber concrete protective body or fiber mesh rubber concrete protective body made of fine steel wire mesh or fiber mesh as reinforced skeleton; the rubber replacement rate of the above rubber concrete is 10%-20%, which is a short Made by mixing fibers and rubber particles into concrete.

[0034] In this embodiment, there are 1-2 layers of fiber mesh and reinforcement mesh, and the mesh size of each layer of fiber mesh and reinforcement mesh is 5mm-15mm; and the fiber mesh is made of carbon fiber, basalt fiber, aramid fiber or glass fiber. The short fibers are steel fibers, glass fibers or natural plant fibers, and the volume content of the short fibers is 0-3%. Rubber pellets are made from discarded rubber tires from cars.

Embodiment 2

[0046] Embodiment 2, referring to Fig. 3 and Fig. 4, differs from Embodiment 1 in that: the protective body is provided with a reserved through hole; the column body 1 is provided with stainless steel bolts 5 corresponding to the reserved through holes, and the stainless steel bolts 5 is fixed by the nut 6 after passing through the reserved through hole and the gasket 7, and the protective body is fixed on the cylinder 1. Structural glue 3 is first injected into the gap between the stainless steel bolt 5 and the column body 1, and then the grouting material 8 is poured in to ensure the stability of the structure. The specific steps are: leveling the surface of the cylinder 1, and drilling according to the reserved through hole of the protective body, after implanting the stainless steel bolt 5, first inject the structural glue 3 into the gap between the stainless steel bolt 5 and the cylinder 1 and grouting material 8; after the stainless steel bolt 5 passes through the protec...

Abstract

The invention discloses an anti-collision protector for a pile body. The anti-collision protector comprises a protector body, wherein the protector body is annularly arranged outside the pile body and is a steel wire mesh rubber concrete protector body or fiber mesh rubber concrete protector body which is made by using a fine steel wire mesh or a fiber mesh in rubber concrete; and the rubber concrete is made by doping concrete with short fibers and rubber particles. The anti-collision protector is simple in structure and can well protect the pile body.

Description

technical field [0001] The invention belongs to the field of column protection, and in particular relates to a column anti-collision protection body. Background technique [0002] Reinforced concrete column structure is currently the most widely used supporting structure. During its service, it may suffer from accidental impacts, such as the impact of vehicles on viaduct piers, and the impact of ships on bridge piers. With the rapid development of the city, there are more and more viaducts, and the possibility of the viaduct piers being hit is also increasing. Viaduct piers (columns) are important load-bearing components of building structures. When they are seriously damaged and destroyed when they are hit, they will inevitably pose a huge threat to people's lives and property safety. In 2008, the New York Department of Transportation conducted a statistical analysis on the damage of different types of bridges, and found that 52% of bridges were damaged due to collisions, ...
