Pile group permeable members used for vertical bank revetment and construction method thereof

Abstract

The invention discloses pile group permeable members used for a vertical bank revetment. The construction method comprises the following steps: piling a plurality of vertical dam piles at the toe of a slope of a construction river, arranging the vertical dam piles into a row along the tail of the slope, laying grids on the inner walls of the vertical dam piles vertically, and casting a plurality of permeable members in the areas surrounded by the grids and a bank slope, so as to form a pile group permeable member dam. The pile group permeable members used for the vertical bank revetment and the construction method thereof have the advantages of stable structure, long engineering service life, ecological and environmental protection, convenience for construction and the like.

Description

technical field [0001] The invention relates to the technical field of waterway regulation, in particular to the anti-scour and silt-promoting and ecological engineering of bank revetment engineering, and relates to a pile group permeable member for vertical bank revetment and a construction method thereof. Background technique [0002] Since the mid-1990s, with the opening of the Yangtze River trunk line (especially the middle and lower reaches) waterway regulation project, the Yangtze River waterway has entered a period of rapid development, and the waterway conditions and cargo volume have greatly increased. According to statistics, since 2005 Since then, it has ranked first in the world's inland rivers for seven consecutive years. [0003] At present, most of the river regulation projects in the middle and lower reaches of the Yangtze River adopt slope revetment, so as to achieve the purpose of protecting the bank slope and returning to the flow. Although the slope type...

AI Technical Summary

Problems solved by technology

Although the slope type revetment has achieved good engineering results, it has the following disadvantages: ① it consumes more building materials such as stone and wood, and the engineering volume is relatively large; The scouring intensifies, and damage will occur in weak parts for a long time, thereby affecting the effect of revetment and affecting the stability of bank slopes; ③With the development of social economy, the land along the river in cities and towns is becoming more and more tense, and there is not enough space to develop slope revetment; ④ Mulch, bottom protection and slope protection sometimes require a large amount of sinking and drainage, which seriously damages the ecology of the river bottom
