Abstract
The utility model discloses a kind of double-deck river structures suitable for mountain stream river, including the upper layer Milky Way and the lower layer underground river being arranged below the Milky Way of upper layer, the upper layer Milky Way and lower layer underground river are spaced from one another, flowing to for the upper layer Milky Way and lower layer underground river is identical, and the upper layer Milky Way, which reduces according to land used size and Transverse to the flow direction or expands hydrophilic waters range, forms the winding upper layer Milky Way；Rectangular in cross-section inside the lower layer underground river, the rectangular in cross-section of the upper layer Milky Way；For the upper layer Milky Way for meeting ecoscape greening and the hydrophilic requirement played with water of visitor, the inner space on the lower layer underground river, which is used to drain off floodwater for flood period, provides fluid space.By the double-deck river structure that the upper layer Milky Way, lower layer underground river is arranged, lower layer underground river solves flood period and crosses flow problem, the upper layer Milky Way solves the problems, such as that dry season visitor is hydrophilic and river channel ecology problem, solves the not strong disadvantage of city depth narrow river safety, hydrophily, landscape.
Description
Technical field
The utility model belongs to hydraulic and hydroelectric engineering field, more particularly, to a kind of double-deck river suitable for mountain stream river
Road 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 best hydraulic radius based on hydraulics, maximum stream flow is conveyed with most economical section.For mankind's flood control, fill
Irrigate, shipping, power generation, land use etc. needs, between river is fixed on dyke by human use's dyke system, using cutting out curved take
Winding natural river transformation is in line or the artificical stream or ditch network of broken line type by straight engineering；For improvement hydrodynamic(al)
Mechanical condition and the purpose of maintain easily, the compound section regular shape of natural river is melted into trapezoidal, rectangle and arc isotactic
Then geometric cross section；Due to safety concerns, important section carries out lining cutting using hard materials such as concrete, stone-layings, causes riverbed material
The hardening of material.
City river section generally has the patterns such as rectangular cross section, trapezoidal cross-section, combined type section.
（1）Rectangular cross section：Project occupation of land is few, and trade culture maximization may be implemented when channel width is restricted.It is applicable in work
The area that journey land used is in short supply, construction space is restricted.Two sides are mostly vertical type barrier wall structure, higher to fundamental importance.It is common
Material have stone masonry or concrete, project durability good.It when channel uses same material river bottom protection, is commonly called as " three face light ", profit
In the dredging of canal bottom and management, but it is unfavorable for the ecological circulation of landscape and canalization.U-shaped reinforced concrete can also be used in rectangular cross section
Soil structure has many advantages, such as good integrity, but cost is higher, and construction technical requirement is high, when especially canal cross section is wider, cost
Index is high, not economical enough.
（2）Trapezoidal cross-section：The appropriate slope in river two sides of trapezoidal cross-section, project occupation of land are big compared with rectangular cross section.Quaywall（Bank
Slope）When using traditional stone masonry bank protection, concrete revetment, equally there is preferable project durability.In recent years, with environment with
The requirement of ecology, many channels use ecomaterial bank protection, have certain landscape and ecological effect, but material roughness is compared with coagulation
Soil material is high, and in the case of the two is with section, smooth concrete flood passage is advantageously.Trapezoidal cross-section will stop riding track width, and adopt
The modes such as pile up with lawn gentle slope or orderly rubble straggly to reach hydrophilic requirement.Allow small flood inundation on tracks certain banks when design
Side facility makes the ordinary water level in river as possible close to platform, allows people that can go to waterside more preferably, keep certain depth of water for a long time, flood
Allow beach thereon when water comes.
（3）Compound cross-section：Compound cross-section is suitable for the open mountain stream river in river shoal.Water flow in dry season is small, and flow returns slot
Main stem.Flood period flow is big, allows flood overbank.Dry season can fully develop the function of river shoal, according to the width of river shoal and
Landform, topography, in conjunction with local practical, exploitation different function.Such as the wealthyer width of beach, golf course, football pitch can be generally developed
Deng large-scale or integrated motion field；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 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 made to combine together with two sides landscape, with urban culture,
Style, history, humane mutually coordination, improve the grade in 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 limit, and city river generally uses rectangular cross section.Especially mountain stream river, flood are sudden and violent
Rise and break, to ensure that the flood control safety of flood period, river are generally deep narrow, revetment, which is lifted off the larger of river bed height difference, need to be arranged shield
The hydrophilic effect of the safeguard measures such as column, river is generally bad.Meanwhile such river water flow in dry season is small, river base flow is small, also shadow
Ring river Ecology.
The design of deep narrow city river at present is summarized, it is ecological generally to have following several ways：（1）It hangs 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
Short hammed water weir is arranged in road bottom, keeps the dry season water surface.Three of the above way is easily realized from engineering technology, wherein
Greening is hung at top from above and the landscape of shore protection surface is most widely used；Shore protection porous material also has developed many new in previous practice
Proximate matter 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, however mould revetment fluidised form is multifarious
Aspect effect unobvious, it is small to be limited by dry season water, it is also difficult to meet for aquatic animal（Such as fish, shrimp）Good dwell is provided
It ceases environment and multiplies the basic demand in space；Hammed water weir also has developed a variety of patterns, and the most commonly used is be combined with landscape at present.
But no matter which kind of processing mode, be limited by the reality of deep narrow river cross-section, hydrophily is undesirable, river without
Method meets the hydrophilic needs of citizen, therefore, the hydrophilic sex chromosome mosaicism or industry great difficult problem in city depth narrow river, it would be highly desirable to solve.
Invention content
The purpose of this utility model is that in order to overcome existing deep narrow river not can be well solved hydrophilic ask
Topic provides a kind of double-deck river structure suitable for mountain stream river, and lower layer underground river meets flood period flood discharge, water drainage requires, on
