Protection type isolation fence for roads and bridges

Abstract

The invention discloses a protection type isolation fence for roads and bridges. The protection type isolation fence comprises a base, a rod sleeve, supporting components, protection rods, a supporting table, a tripod, a connecting hoop, connecting plates, fixing holes, a center rod, a reset spring, limiting rods, supporting rods, rubber gaskets, clamping columns, top plates, buckles, buffer springs and bearing columns. The isolation fence has the advantages that the common effect among the parts is used so that the collision strength of a vehicle can be reduced from multiple angles, and an improvement is made on the basis of original rigid isolation. The connecting hoop on the top of the isolation fence is connected to a preset connecting rod through the connecting hoop, so that the devices jointly form an isolation layer; the supporting function is achieved through the base and the supporting components. When a traffic accident occurs, the transverse impact of the vehicle makes the protection rods drive the rod sleeve to rotate, the reset spring in the rod sleeve can buffer the transverse impact, and the longitudinal impact force of the vehicle can be buffered through the supporting rods and the buffer springs in the limiting rods.

Description

technical field [0001] The invention relates to a protective isolation fence, in particular to a protective isolation fence for roads and bridges, belonging to the field of road and bridge facilities. Background technique [0002] With the vigorous development of modern transportation industry, the number of high-grade highways, mainly expressways and first-class roads, has increased year by year. my country's highway industry has entered a new stage focusing on the construction of high-grade highways. However, limited land resources cannot meet the needs of high-grade roads. The number of works of highways, therefore, roads and bridges began to appear on the designer's design drawings. Like ordinary roads, traffic accidents also occur on roads and bridges, which often lead to greater economic and personnel losses. Therefore, a protective barrier begins to appear on the bridge pavement. [0003] The existing isolation fences used on road and bridge pavements have certain def...

AI Technical Summary

Problems solved by technology

[0003] The existing barriers used on roads and bridges have certain defects in their design. First of all, the general barriers used on roads and bridges can only play an isolation role and cannot achieve "protection". When the secondary loss is reduced, the degree of loss that has already occurred cannot be reduced

Secondly, the general barriers used on roads and bridges cannot be easily disassembled and repaired after being damaged.
