AI Technical Summary

Technical Problem

In special environments such as Gobi and deserts, the service life and performance of ordinary bridge support have significantly decreased due to wind and sand, which is difficult to meet the functional and durability requirements of bridges in desert areas for support.

Method used

A windproof sand support for bridges is designed, including a sealed expansion joint assembly between the upper support and the lower support. The sealed expansion joint assembly consists of a stretchable or compressible length reserve section and a support connecting section, combining a planar friction pair and a curved friction pair to ensure that the support remains fully enclosed under various working conditions.

Benefits of technology

This design realizes flexible adaptation of the bearing in the condition of displacement, angle, etc., ensures the stability and normal use of the bridge structure, extends the service life of the bearing, reduces the frequency of maintenance and replacement, and reduces the cost of bridge operation and maintenance.

Abstract

The invention discloses a wind and sand prevention support for a bridge and a mounting structure of the wind and sand prevention support. The wind and sand prevention support comprises an upper support and a lower support, and a sealing expansion joint assembly is detachably fixed between the upper support and the lower support; the sealing expansion joint assembly comprises a sealing expansion joint connected between the upper support and the lower support and a fixing assembly used for detachably fixing the sealing expansion joint to the upper support and the lower support. A closed space is defined by the upper support, the lower support and the sealing expansion joint assembly. The length storage section capable of being stretched or compressed is arranged in the designed sealing expansion joint assembly, and the multiple stretching sections and the stretching connecting sections can change the length size through stretching, so that the support can flexibly adapt to the conditions of displacement, corner and the like; therefore, the functional requirements of displacement, corner and the like caused by various factors in the use process of the bridge are met, and the stability and normal use of the bridge structure are guaranteed.
