Pier anti-collision facility in scoured area and construction method thereof

Abstract

The invention discloses a pier anti-collision facility in a scoured area and a construction method of the pier anti-collision facility. The pier anti-collision facility in the scoured area is mainly composed of embedded steel bars (1), fixed groove-shaped steel plates (2), sliding steel plate rubber assemblies (3), steel sleeves (4) and annular reinforced concrete columns (5). The bridge pier anti-collision facility is arranged on the outer side of a bridge pier in the direction perpendicular to the height direction of the bridge pier and can vertically move in the height direction of the bridge pier, when the bridge pier descends due to scouring, the facility can descend to a new ground position accordingly, and it is guaranteed that the bridge pier anti-collision facility is located above the bridge pier ground all the time; the situations that the pier anti-collision facility is invalid and the pier is not protected by the anti-collision device due to the fact that the pier anti-collision facility is disengaged from the ground due to scouring of a conventional fixed pier anti-collision facility are avoided. The bridge pier anti-collision device is suitable for the bridge pier ina scouring area, when the ground at the bridge pier continuously descends due to scouring, the bridge pier anti-collision device can be located above the bridge pier ground all the time, and effectiveness of the bridge pier anti-collision device is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bridge structures, and in particular relates to a bridge pier anti-collision facility in a scoured area and a construction method thereof. Background technique [0002] The construction of highway transportation has far-reaching significance to the economic development of mountainous areas, and plays an important role in accelerating logistics, promoting industrial and urbanization processes, improving travel conditions, and accelerating economic development in areas along the route. my country's terrain is complex and diverse, and the area of ​​mountainous areas is vast. The area of ​​mountainous areas accounts for 2 / 3 of the country's land area. Therefore, there are many roads in mountainous areas. Mountainous roads have the characteristics of high mountains and deep valleys, large height differences, and complex terrain and geology; many bridges span deep valleys and gullies, and some bridge piers are ...

AI Technical Summary

Problems solved by technology

However, in mountainous areas, as the deep valleys and gullies are continuously washed by rainwater, the ground of the deep valleys and gullies continues to decline, and the anti-collision facilities of the bridge piers connected to the ground will gradually separate from the ground, and the distance between them will gradually increase. There is a gap between the anti-collision facilities of the pier and the ground, resulting in the failure of the anti-collision facilities of the pier and no protection of the anti-collision facilities for the pier
