Description
Technical field
The invention belongs to Hydraulic and Hydro-Power Engineering field, more particularly, to a kind of double-deck river course knot suitable for mountain stream river course
Structure.
Background technology
There are rich and varied river regime, section and dynamic variation tendency in natural river.Traditional river regulation reason
By the concept for being the optimal hydraulic radius based on hydraulics, maximum stream flow is conveyed with most economical section.For mankind's flood control, fill
Irrigate, shipping, generating, the need for land use etc., river is fixed between dyke by human use's dyke system, using cutting out curved take
Straight engineering by cranky natural river transformation be in line or broken line type artificical stream or ditch network；For improvement hydrodynamic(al)
Mechanical condition and the purpose such as maintain easily, the compound section regular shape of natural river is melted into trapezoidal, rectangle and arc isotactic
Then geometric cross section；For security consideration, important section carries out lining cutting using hard materials such as concrete, stone-layings, causes riverbed material
The hardening of material.
City river section typically has the patterns such as rectangular cross section, trapezoidal cross-section, combined type section.
（1）Rectangular cross section：Project occupation of land is few, can realize that trade culture is maximized when channel width is restricted.It is applicable work
The area that journey land used is in short supply, construction space is restricted.Two sides are generally vertical type barrier wall structure, higher to fundamental importance.It is conventional
Material have stone masonry or concrete, project durability is good.When channel uses same material river bottom protection, it is commonly called as " three face light ", profit
In the desilting of canal bottom and management, but it is unfavorable for the ecological circulation of landscape and canalization.Rectangular cross section can also use U-shaped reinforced concrete
Soil structure, has the advantages that good integrity, but cost is higher, and construction technical requirement is high, when especially canal cross section is wider, its cost
Index is high, not economical enough.
（2）Trapezoidal cross-section：The appropriate slope in river course two sides of trapezoidal cross-section, project occupation of land is big compared with rectangular cross section.Quaywall（Bank
Slope）During using traditional stone masonry bank protection, concrete revetment, equally with preferable project durability.In recent years, with environment with
Ecological requirement, many channels use ecomaterial bank protection, and with certain landscape and ecological effect, but material roughness is compared with coagulation
Soil material is high, and in the case of both are with section, smooth concrete flood passage is advantageously.Trapezoidal cross-section will stop packway width, and adopt
The mode such as pile up to reach hydrophilic requirement with lawn gentle slope or orderly rubble straggly.Allow small flood inundation on tracks some banks during design
Side facility, makes the ordinary water level in river course try one's best platform, allows people to go to waterside more preferably, certain depth of water is kept for a long time, flood
Allow beach thereon when water comes.
（3）Compound cross-section：Compound cross-section is applied to the open mountain stream river course in river shoal.Water flow in dry season is small, and current return groove
Main stem.Flood period flow is big, it is allowed to flood overbank.Dry season can fully develop the function of river shoal, according to the width of river shoal and
Landform, physical features, with reference to local actual, develop difference in functionality.Such as the wealthyer width of beach, golf course, football pitch can be typically developed
Etc. large-scale or integrated motion；River shoal relative narrower, can build small-sized outdoor sports place, riverside park or relief road etc..
The rational exploitation and utilization of river shoal, can give full play to the function of river shoal, and not raise flood level because enclosing beach, aggravate the anti-of two sides
Big vast pressure.
Urban River Restoration should be combined with water environment treatment, when Section Design is with greening riverbank, should protrude hydrophilic life
State, makes the water environment of " safety, landscape, leisure ", river training works is combined together with two sides landscape, with urban culture,
Style, history, the humane grade mutually coordinated, improve cities and towns, improve the environment that people live.But due to land used limitation and two sides
The factors such as building dense, removal difficulty are limited, and city river typically uses rectangular cross section.Especially mountain stream river course, flood is sudden and violent
Rise and break, to ensure the flood control safety of flood period, river course is generally deep narrow, and revetment, which is lifted off the larger of the river bed discrepancy in elevation, need to set shield
The safeguard measures such as column, the hydrophilic effect in river course is not general good.Meanwhile, such river course water flow in dry season is small, and river course base flow is small, also shadow
Ring river course Ecology.
The design of deep narrow city river at present is summarized, its is ecological typically there are following several ways：（1）Hung down at the top of shore protection
Hang greening；（2）Shore protection surface preventing material uses the rectangular slab of stone, block stone or porous material, prominent landscape or ecological effect；（3）River
Road bottom sets short harmony mill weir, keeps the dry season water surface.The easily realization from engineering technology of three of the above way, wherein,
Greening is hung at top from above and the landscape of shore protection surface is most widely used；Shore protection porous material also have developed many new in conventional practice
Section bar material and technology, such as green concrete, ecology bag, Ecotypic Stone Mesh-box, concrete segment, solidified earth planting matrix.These materials
Material and technology help to solve the problems, such as the slope greening of river alongshore and water and soil conservation, but mould revetment fluidised form is multifarious
Aspect DeGrain, is limited by dry season water small, it is also difficult to meet as aquatic animal（Such as fish, shrimp）Good dwell is provided
Cease the basic demand in environment and procreation space；Harmony mill weir also have developed a variety of patterns, is most commonly combined at present with landscape.
