Embodiment 1

[0034] refer to Figure 1a , a double-layer channel structure suitable for mountain stream channels, including an upper open river and a lower underground river set below the upper open river. The upper open river and the lower underground river are separated from each other. The cross-section of the Ming River is rectangular; the upper Ming River is equipped with aquatic plant areas and tourists' water areas to meet the requirements of ecological landscape greening and tourists' water play. Various sculptures can also be set up to form diversified landscape elements and enrich the river landscape. Connotation; the inner space of the underground river in the lower layer is used to provide a flow space for the flood discharge during the flood period. The upper clear river can also appropriately reduce or expand the range of hydrophilic waters according to the size of the land and the direction of vertical water flow, forming a meandering upper channel shape. The underground riv...

Embodiment 2

[0040] refer to Figure 2a and 2b , in this embodiment, the box-culvert-type underground river is a double-hole structure.

[0041] Refer to Example 1 for other components.

Embodiment 3

[0043] refer to Figure 3a , a double-layer channel structure suitable for mountain stream channels, including an upper open river and a lower underground river set below the upper open river. The upper open river and the lower underground river are separated from each other. The cross-section of the Ming River is rectangular; the upper Ming River is equipped with aquatic plant areas and tourists' water areas to meet the requirements of ecological landscape greening and tourists' water play. Various sculptures can also be set up to form diversified landscape elements and enrich the river landscape.

Abstract

The invention belongs to the field of hydraulic and hydropower engineering, and in particular, relates to a double-layer river channel structure suitable for a mountain stream river channel. The double-layer river channel structure is provided with an upper layer of ground river and a lower layer of underground river; the lower layer of underground river solves the overcurrent problem in the flood period; and the upper layer of ground river solves the tourist hydrophilic problem and the river channel ecological problem in the drought period, so that the defects of low safety, hydrophile and landscape of urban deep and narrow river channels are solved. Meanwhile, according to the river channel land and structure characteristics, the lower layer of underground river can be constructed by combining with a foundation pit envelope pile structure, so that the problems of higher slope excavation land occupation and higher disturbance on surrounding construction in traditional river channel construction are solved.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering, and in particular relates to a double-layer channel structure suitable for mountain stream channels. Background technique [0002] Natural rivers have a variety of river regimes, cross-sections and dynamic trends. The traditional river management theory is based on the concept of the optimal hydraulic radius in hydraulics, and the most economical section is used to transport the maximum flow. For the needs of human flood control, irrigation, shipping, power generation, land use, etc., human beings use embankment systems to fix rivers between embankments, and use cutting and straightening projects to transform winding natural rivers into straight or zigzag artificial ones. Rivers or artificial river networks; for the purpose of improving hydrodynamic conditions and facilitating maintenance, the complex section shapes of natural rivers are regularized into regular geomet...
