Bridge-crossing pipeline supporting device and bride provided with supporting device

Abstract

The invention discloses a bridge-crossing pipeline supporting device and a bride provided with the supporting device and relates to the field of design of accessory structures of bridges. The supporting device comprises a horizontal support and two suspending frames. The horizontal support is installed below the bridge and is provided with a circular arc surface for a pipeline to be placed, the two suspending frames are respectively arranged on two sides of the horizontal support, one end of each suspending frame is connected with the bridge, the other end of each suspending frame is connected with the horizontal support, and the suspending frames are provided with elastic parts. The horizontal support further comprises cross beams and a base. The supporting device is good in flexibility, keeps the pipeline stress balanced and is safe and reliable, the suspending frames are not easily damaged, the cost is saved, installation is convenient, and maintenance is simple. The bride provided with the supporting device comprises two floating bridges arranged at an interval, and the suspending frames of the supporting device are respectively connected with the two floating bridges. When the automobile loading effects borne by the floating bridges are different to produce different degrees of transverse displacements, the pipeline can be also placed stably, and an application range is wider.

Description

technical field [0001] The invention relates to the field of bridge accessory structure design, in particular to a support device for a bridge-passing pipeline and a bridge equipped with the support device. Background technique [0002] When the pipeline passes through the bridge, due to the limitation of the bridge site, it is generally suspended under the bridge, so it is necessary to use bridge brackets to support the suspended pipeline. At present, the bridge supports mostly adopt rigid supports. However, during the operation of the bridge, the bridge is prone to longitudinal deflection, which leads to the hollowing out of part of the rigid support in the depression, the increase of the span of the pipeline, and the increased stress on the suspenders that are not freed from the rigid support, which is prone to damage. In addition, the vehicle loads on the left and right bridges are different, which will also produce different degrees of lateral displacement. The suspend...

AI Technical Summary

Problems solved by technology

However, during the operation of the bridge, the bridge is prone to longitudinal deflection, which will cause part of the rigid support in the depression to fall out, increase the span of the pipeline, and increase the stress on the suspenders that are not freed from the rigid support, which is prone to damage

In addition, the vehicle loads on the left and right bridges are different, which will also produce different degrees of lateral displacement. The suspenders on both sides of the pipeline are unbalanced, which is easy to cause damage on the one hand, and on the other hand, makes the pipeline unbalanced, and there is a safety hazard. Hidden danger

After the suspender of the rigid support is damaged, not only the maintenance cost is high, but also the rigid support is difficult to repair
