Abstract
The utility model discloses a be suitable for city river's compound seepage prevention structure of multilayer passes through bed course, gland wash -prime coat on, and constitutes by setting up the lower transition bed course on the riverbed, geotechnological loaded filter, geotechnological material owner barrier layer from bottom to top. The utility model discloses the advantage embodies: 1, the compound seepage prevention structure of multilayer makes riverbed anti dash can the reinforce, has solved present seepage prevention structure and has been difficult to satisfy and moves prevention of seepage needs under the water condition, provides solution method for the prevention of seepage in river course, many functional requirement that control flood. 2, set up geotechnological loaded filter under the geotechnique material owner barrier layer, play the geotechnological material owner barrier layer of protection, prevent the effect that its seepage deformation destroyed. 3, each layer material is material commonly used to can select suitable material according to different river courses condition, convenient purchase and construction. 4, each layer material is flexible material, and structural stability can be good. 5, the gland wash -prime coat adopts the porous material of permeable waterborne, provides favourable place for underwater plant grows, the animal perches.
Description
Technical field
The present invention relates to river course leakage preventing structure, especially relate to the city river MULTILAYER COMPOSITE leakage preventing structure be suitable under river channels.
Background technology
Along with modern city is constantly developed, the grade requirement of people to city is also more and more higher, greening and water system more and more become the key that city taste promotes, for the city of water resource relative shortage, utilizing city river to build landscape impoundments, view reservoir etc. becomes the indispensable ingredient of urban development.Therefore often need to carry out Anti-seeping technology under the precondition meeting flood passage when city river is administered, need like this to select the leakage preventing structure form that adaptive deformation ability is strong, good seepage-proof property, erosion resistibility are strong under city river river channels.The more city river leakage preventing structure of current application has: concrete slab is anti-blends clay core, all there is respective weak point in these two kinds of city river leakage preventing structures: concrete slab Seepage is complicated and cost is higher, temperature influence easily produces crack, simultaneously because concrete slab makes water body and body of groundwater completely isolated, be unfavorable for the exchange of ecology.Clay core not only volume of earthwork is large, make revetment antiseepage be difficult to process, and under moving water state, clay easily runs off, and for city, finds the cost of tonerde to be also suitable height.
Summary of the invention
The object of the invention is to provide a kind of MULTILAYER COMPOSITE leakage preventing structure being suitable for city river, and to solve the deficiency that existing city river adopts hydrostatic leakage preventing structure, under making the river channels of city river when flood passage, impervious barrier is not destroyed, and can reach anti-seepage effect simultaneously.
For achieving the above object, the utility model takes following technical proposals:
The MULTILAYER COMPOSITE leakage preventing structure being suitable for city river described in the utility model, by being arranged on the lower transition bed course on riverbed from bottom to top, geotechnological loaded filter, the main impervious barrier of earth working material, upper transition bed course, gland wash-prime coat form.
Described lower transition bed course, upper transition bed course are sand gravel or lam, and the particle diameter of described sand gravel is clay content >=15% of 2 ~ 5mm, described lam; The main impervious barrier of described earth working material is geomembrane or waterproof blanket; Described geotechnological loaded filter is geotextiles; Described gland wash-prime coat is lattice guest cage stone or stone-laying water permeability porous material.
The utility model advantage major embodiment is:
1, adopt MULTILAYER COMPOSITE leakage preventing structure to make the impact resistance in riverbed strong, solve existing leakage preventing structure be difficult to meet river channels under antiseepage needs, for the multi-functional demand such as antiseepage, flood control in river course provides effective solution.
2, under the main impervious barrier of earth working material, geotechnological loaded filter is set, the effect play the main impervious barrier of protection earth working material, preventing its seepage deformation from destroying.
3, each layer material is common used material, and according to different river courses condition, can choose suitable material, convenient buying and construction.
4, layers of material is flexible material, and Stability Analysis of Structures performance is good, adapts to various landform, geological conditions.
5, gland wash-prime coat adopts the porous material of porous, for underwater plant growth, animal habitat provide favourable places.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the MULTILAYER COMPOSITE leakage preventing structure being suitable for city river described in the utility model, is made up of the lower transition bed course 1 be arranged on from bottom to top on riverbed 6, geotechnological loaded filter 2, the main impervious barrier of earth working material 3, upper transition bed course 4, gland wash-prime coat 5; The main impervious barrier of earth working material 3 selects the conventional seepage by geo-textile material such as geomembrane, waterproof blanket, and impervious material thickness needs calculating to determine according to antiseepage; Lower transition bed course 1, upper transition bed course 4 all select sand gravel or lam, to play the effect of the main impervious barrier 3 of available protecting earth working material; When selecting sand gravel, the particle diameter of sand gravel is 2 ~ 5mm, when selecting lam, and clay content >=15% of lam; Geotechnique's loaded filter 2 adopts geotextiles, and the thickness of geotextiles is selected according to design needs; Gland wash-prime coat 5 adopts the porous material of the porous such as lattice guest cage stone or stone-laying, and to increase the ecological effect of structure, the thickness of gland wash-prime coat 5 is chosen according to dynamic water flow velocity size.
