Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The rigid-flexible laminated pier rolling stone impact protection structure of the present invention is suitable for the impact protection of bridges in mountainous areas, such as figure 1 As shown, it includes a flexible inner core buffer layer 2 wrapped on the outer wall of the pier 1, and a tubular rigid surface protection layer 3 is also arranged on the outer wall of the flexible inner core buffer layer 2, such as Figure 2-Figure 3 As shown, the flexible inner core buffer layer 2 and the segmented rigid surface protection layer 3 are connected and fixed to the bridge pier 1 through the preset pre-embedded steel bars 5 preset on the bridge pier 1 .

[0030] The pre-embedded steel bars 5 are evenly distributed on the circumference of the pier 1 and the pre-embedded steel bars 5 extend along the radial direction of the pier 1 and tow...

Abstract

The invention discloses a rigid-flexible laminated bridge pier rock-fall impact protection structure. The rigid-flexible laminated bridge pier rock-fall impact protection structure comprises a flexible inner core buffering layer coating the external side wall of a bridge pier; a tube and fin type rigid surface layer protection layer is also arranged on the external side wall of the flexible innercore buffering layer; and the flexible inner core buffering layer and the tube and fin type rigid surface layer protection layer are connected and fixed to the bridge pier through embedded reinforcements which are pre-arranged on the bridge pier. According to the rigid-flexible laminated bridge pier rock-fall impact protection structure, by combining the flexible inner core buffering layer and thetube and fin type rigid surface layer protection layer, the anti-impact performance of the bridge pier is improved, the service life of the bridge pier is prolonged, and an effective protection requirement is satisfied. The invention further discloses a making method of the rigid-flexible laminated bridge pier rock-fall impact protection structure.

Description

technical field [0001] The invention belongs to the technical field of impact protection engineering structures, and relates to a rolling stone impact protection structure of a rigid-flexible laminated bridge pier, and also relates to a manufacturing method of the rolling stone impact protection structure of a rigid-flexible laminated bridge pier. Background technique [0002] Rolling stone disasters are extremely harmful to lifeline projects. In recent years, the frequency and scale of rolling stone disasters in my country have increased rapidly. With the construction of a large number of transportation infrastructure and the increase of the ratio of bridges and tunnels, it is urgent to protect bridges in mountainous areas from the impact of rolling stones. As an important part of bridge engineering, the bridge pier will lead to failure of the bridge structure after being damaged by the impact of rolling stones, and the damage consequences are quite serious. [0003] In or...
