Description
Technical Field
The utility model relates to a pile foundation construction technical field in the bridge construction operation, concretely relates to buffering shock attenuation permanence steel that anti mud-rock flow strikes protects a section of thick bamboo.
Background
The underwater pile foundation is worn by water flow, floaters and the like for a long time, the concrete is gradually worn away, a concrete protective layer around a local part or the whole pile diameter is thinned, in addition, carbonization and chloride ion erosion of the concrete can cause damage of an alkaline passive film covering the surface of the steel bar, and the steel bar is corroded after water and oxygen invade. The steel bar is corroded and then undergoes volume expansion, the concrete is cracked along the steel bar, the binding force between the steel bar and the concrete is damaged, the section area of the steel bar is reduced, the bearing capacity of the structural member is reduced, the corrosion is gradually deteriorated along with the lapse of time, and the complete damage of the structure can be caused. The corrosion-resistant pile body mainly comprises rust spots, rust expansion, cracking along the reinforcing steel bars and concrete falling, the pile body section is positioned in a scouring area, the concrete falls off rapidly under the action of water flow after the reinforcing steel bars are corroded, the reinforcing steel bars are exposed, the corrosion speed of the reinforcing steel bars is accelerated, and therefore the scouring and the corrosion of the reinforcing steel bars often interact with each other to accelerate the damage of the pile body. The diseases can cause the bearing capacity of a bridge pile foundation structure to be reduced, even cause the bridge pile to be suddenly unstable and collapsed, and seriously affect the traffic safety.
Disclosure of Invention
