Buffer structure

Abstract

The invention relates to a buffer structure which comprises concrete substrates, wherein the periphery of each concrete substrate is respectively provided with at least one joint groove relatively; the concrete substrates are provided with a plurality of buffer components; the periphery of each buffer component is correspondingly provided with fixing holes, a plurality of first joint components and a plurality of second joint components; the first joint components penetrate through the fixing holes for connecting the buffer components in series; and the second joint components are embedded in the joint grooves to connect the plurality of concrete substrates with the same structure. The buffer structure is paved around a bridge or a dike of a river for buffering the impact of flood torrent by the buffer components in order to avoid scouring or caving the dike or the bridge of the river.

Description

technical field [0001] The invention relates to a buffer structure, in particular to an infrastructure suitable for preventing bridge piers from impacting or riverbeds around embankments being emptied by floods. Background technique [0002] By the way, when a typhoon or heavy rain strikes, a huge amount of rainfall often falls in a short period of time, causing the water volume of the river to increase and the water level to rise, so that the foundation piles of the bridges built on these rivers will be exposed or the riverbed around the embankment will be emptied. Accidents such as broken bridges and embankments have occurred. However, the various protection measures currently taken for the riverbed around the exposed bridge piers and embankments, such as placing wave-absorbing blocks, may still be washed away or easily damaged if the water flow is too large and rapid; Strong washing and impact of sand and gravel for a long time will often wear and break and cause continu...

[0002] By the way, when a typhoon or heavy rain strikes, a huge amount of rainfall often falls in a short period of time, causing the water volume of the river to increase and the water level to rise, so that the foundation piles of the bridges built on these rivers will be exposed or the riverbed around the embankment will be emptied. There have been accidents such as broken bridges, embankments, etc.

However, the various protection measures currently taken for the riverbed around the exposed bridge piers and embankments, such as placing wave-absorbing blocks, may still be washed away or easily damaged if the water flow is too large and rapid; Strong washing and impact of sand and gravel for a long time will often wear and break and cause continuous emptying; if all reinforced concrete is used for a long time, strong sand and gravel washing will also break through or damage, so despite the above measures, bridge breaks and collapses often occur dike events

[0003] The above-mentioned broken bridge crisis is caused by the exposed and emptied foundation piles of the bridge. The main reason for the exposed and emptied foundation piles is that the sand and gravel industry is mining sand and gravel in the upper reaches of the river, which makes the river unable to dispose of enough sand. The erosion of rocks to the middle and lower reaches makes the height of the middle and lower reaches of the riverbed continue to drop. Coupled with the long-term erosion of the river or the strong impact of the flood, the foundation piles of the bridge originally planted deeply under the riverbed are exposed or are washed away by the water. empty, thus forming a dangerous bridge with a crisis of broken bridge
