One kind of collision pier structure and design method

The present invention discloses a collision pier structure and its design method. Existing anti-collision device for the presence of the pier off easily damaged, the processing cost is uneconomical, convenient installation and maintenance and other defects, the present invention provides a first collision pier structure. The method of the present structure is a collision pier eccentric design, the inner tubular member and the outer tubular member comprises a telescoped inner and outer, the inner tube and the outer tube sleeved eccentric, the outer tubular member axially parallel; inner, outer the thickness of the filling layer of cushioning material, cushioning layer between the material layer has a maximum δ tube in the direction of impact of multiple vehicle. Between the inner tube and the use of fine aggregate piers coupled pouring concrete layer. Under optimized conditions, the inner and outer tubular member using Tongwa combined structure. The outer tube is round or oval two kinds. The present invention also provides a method of designing an eccentric circular and elliptical eccentric structure. Simple product structure of the present invention, security, good protective effect, save timber cost, reliable design principle of the method, science is simple.
