Automatic filled road-bridge transitional attachment strap member

Abstract

The invention relates to transition brow plate for filling road and bridge. It is made up of material pouring hole, observing hole, auto filling material outlet hole, material storing cavity, closure plate, and reinforcing prop. The structure has auto filling function to pour finely particle filling material. When the road settles, the clearance between the road and the brow plate would be formed, and the filling material would automatically fill the clearance.

Description

technical field [0001] The invention belongs to building components in the field of road construction. Background technique [0002] In the known technology, when dealing with the butt joint of soft ground pavement and hard ground pavement; when the bridge, culvert surface and pavement joint and transition board are adopted, the following methods are generally used for pretreatment: [0003] 1. Preloading method: [0004] Use vertical drainage wells and lime piles, firstly use the same total load as the embankment to preload the abutment subgrade, and then remove the preload after the foundation settlement is stable. [0005] 2. Balanced weight embankment method: [0006] On the basis of the preloading method, a bridge column abutment is adopted, and piles are drilled on the embankment after the preloading settlement is completed. [0007] 3. Bridge head strap: [0008] Longer and deeper slabs are used to eliminate the staggered platform caused by settlement. [0009] 4...
