River embankment structures for building sponge cities

Abstract

The invention discloses a riverway embankment structure for constructing a sponge city. The riverway embankment structure includes a riverway base plate and a retaining wall, the riverway base plate includes a plurality of partition plates, the partition plates are rectangular plates or arc-shaped plates, the multiple partition plates are located at the bottom of a riverway, the length directionsof the partition plates are arranged in sequence in the flowing direction of the riverway, the width directions of the multiple partition plates are successively arranged in parallel in the width direction of the riverway, every two adjacent partition plates are spaced to form a water seepage groove for water seepage at the bottom of the riverway, the water seepage grooves are internally providedwith water seepage systems, the retaining wall is further provided with a drainage system, and the drainage system is arranged in the lower middle part of the retaining wall. The structure can be usedfor riverway embankment construction for the sponge city, the structural strength of an riverway embankment is improved while the water seepage ability is ensured.

Description

technical field [0001] The invention relates to the technical field of urban water conservancy facilities, in particular to a river embankment structure for constructing a sponge city. Background technique [0002] Traditional urban construction ideas emphasize hardening the water surface as much as possible, isolating water flow, and preventing seepage, including road surfaces, river channels, especially the bottom plates of river channels, and retaining walls on both banks. As a result, runoff, that is, the flow of surface water, has been greatly increased, and the water tolerance and elasticity of cities, especially along river channels, have been reduced. What's more serious is that the river bed and slopes were often closed and solidified in the past river course improvement, which made it impossible for the water flow to communicate with the outside world when flowing through the urban area, cutting off the exchange of materials, energy and information among the variou...

Problems solved by technology

The invention patent application with the notification number CN 106049348B discloses a retaining wall structure for sponge city construction. Drain the excess water in the river channel into the fill land behind the retaining wall. When natural disasters such as floods come, the water level rises very quickly. This kind of water seepage method requires more outlets to meet the drainage requirements. Too many reverse permeable systems will cause the structure of the retaining wall to be unstable, and under the erosion of disasters, it will cause damage to the retaining wall
