Problems solved by technology

[0005] The present invention aims at the current situation that urban rivers generally cannot reuse and recycle flood resources, and the existing river slope protection is mostly based on mortar rubble slope protection and hole-type slope protection, which is not suitable for the concept of ecological river bank protection. Renovate the control system to make full use of rain and flood resources

Embodiment 1

[0018] Embodiment 1: An urban river channel rain and flood resource control system, which aims to control, store and utilize the precipitation in the flood season, which accounts for more than half of the annual precipitation, through various methods, make full use of the rainfall and floods in the flood season, and prevent the natural runoff in the flood season from causing a large amount of water Waste of resources.

[0019] The reconstruction of urban rivers should be carried out according to the specific conditions of the terrain, and the slope protection surface on one side or both sides of the river can be adopted such as figure 1 The retrofit structure shown. exist figure 1 Among them, the surface layer of the slope protection has a permeable pavement layer 5, a vegetation soil layer 4 and a fiber layer from outside to inside to form a surface unit, wherein the permeable pavement layer 5 of the surface unit is planted with vegetation in the permeable holes, and the roo...

Embodiment 2

[0024] Embodiment 2: On the basis of implementing the water storage function of the slope protection surface layer and the water storage function of the clear water culvert in the embodiment 1, the municipal comprehensive utility gallery 13 is further combined with the clear water culvert to achieve the purpose of more fully utilizing the rain and flood resources. Among them, the clear water culvert set in embodiment 1 needs to be determined according to the specific conditions of the river channel and geological conditions, and the clear water culvert can be set in the whole or part of the river channel slope protection according to necessity. Then set the municipal comprehensive pipe gallery 13 in the whole or part of the soil layer 12 in the parallel direction of the clear water culvert, or arrange the whole section or part of the clear water culvert according to the arranged municipal comprehensive pipe gallery 13 to be juxtaposed with it.

Embodiment 3

[0027] Embodiment 3: On the basis of Embodiment 1 or Embodiment 2, in this embodiment, the section from the lower part of the surface unit to the river bed subgrade 1 can be used as a return section, and the return section can exceed the river bed subgrade 1 when the river water level soars. After reaching the hardened area of ​​slope protection, drain water into the clear water culvert through the return section to realize the function of flood storage. Specifically, such as figure 1 As shown in , the return section includes the surface permeable pavement 5, the middle fiber layer and the bottom percolation layer 20. After the river water level exceeds the river bed subgrade 1, the river water will replenish water to the clear water culvert through the return section.

[0028] In addition, this embodiment can further adopt such as image 3 In the flood discharge method shown, a flood discharge channel 21 is provided in part of the return section, and the flood discharge chan...

Abstract

The invention discloses an urban river channel stormwater resource control system. The surface layer of slope protection on one or both sides of a river embankment is sequentially composed of a permeable pavement layer, a vegetation soil layer and a fiber layer from the outside to the inside to form a surface unit, and the permeable pavement layer of the surface unit Vegetation is planted in the permeable holes; the bottom of the upper part of the surface unit is paved with a gravel material infiltration layer, and the middle part of the surface unit is distributed with cascade bioretention purification tanks. Large-area gravel material seepage layer, at the bottom of the large-area gravel material seepage layer, a clear water culvert is opened to store and filter rainwater. The present invention can collect rainwater resources through various ways, and can realize almost all receiving and utilization of rainwater resources through various ways.

Description

technical field [0001] The invention relates to the technical field of regulation and control of urban rainwater resources, in particular to a rainwater resource regulation system suitable for urban river channel reconstruction. Background technique [0002] The total amount of urban water resources in northern my country is insufficient, and the distribution is uneven from year to year, making it difficult to utilize rain and flood resources, resulting in a prominent contradiction between supply and demand of water resources. After implementing a series of measures to increase revenue and reduce expenditure, and the South-to-North Water Diversion Project, the basic balance of water supply and demand can be achieved. However, the dependence on external water sources (Yellow River water, Yangtze River water) in the water supply structure has increased, and external water sources account for 30% of the total water supply. %about. In many cities, the precipitation in the flood...
