AI Technical Summary

Technical Problem

The existing bridge pier anti-collision facilities have the following problems: the steel structure is easy to corrode, the maintenance cost is high, the bonding strength of the steel-covered composite material is low, it is easy to peel off during collision, and it is easy to cause puncture of the hull.

Method used

The concrete porous metal composite anti-collision structure adopts a honeycomb structure, including cells, a first buffer layer and a second buffer layer. The energy absorption characteristics of the honeycomb structure and the buffer layer are utilized, and the anti-eccentric load capability and deformation uniformity are improved through the coupling effect of the cells. Combined with the pore structure of the foam concrete material, the energy absorption efficiency is improved.

Benefits of technology

A lightweight, high-energy-consuming and durable anti-collision structure has been achieved, which significantly improves the energy absorption capacity and anti-eccentricity performance, reduces maintenance costs and avoids hull damage.

Abstract

The utility model provides a concrete porous metal composite anti-collision structure, which relates to a bridge anti-collision device and comprises a plurality of cells arranged in parallel to form a honeycomb structure. The utility model relates to a honeycomb structure, which comprises a plurality of cell elements, a first buffer layer and a second buffer layer, the first buffer layer is arranged in each cell element, the second buffer layer is arranged on the outer surface of the honeycomb structure, and a plurality of air holes are formed in the first buffer layer and the second buffer layer. On the basis, the unbalance loading resistance of the honeycomb structure and the compression deformation capacity of the first buffer layer and the second buffer layer are improved through the coupling effect between the components, and in addition, due to the fact that the first buffer layer is arranged in the cell element, the cell element obtains high specific mass energy absorption and specific volume energy absorption.
