Description
Technical field
The present invention relates in the revetment barricade engineering of a kind of navigation channel the reinforced earth lightweight revetment barricade applying the ecological mask of building-block, be applicable to that collapse on the bank is serious, the navigation channel of soft clay area or riverbank.This invention overcomes the drawback of conventional rigid shore protection Gravity Retaining Wall from the process of great desirably base, substantially solve collapse on the bank, current and ship wave to bank slope wash away and vessel to the problem that may clash into of bank protection structure, achieve the combination of bank protection structure durability and ecological property.The invention still further relates to the construction method of this lightweight revetment barricade.
This patent is by the special project " western middle and small river and bank slope bionomic control complete set technology research (No:201301022) thereof " of Ministry of Water Resources's public welfare industry scientific research, Jiangsu Province's traffic and transportation science research program project " red golden Li river for transporting grain to the capital informer times waterway regulation (red golden ship lock) engineering navigation channel soil bank slope Ecological recovery technology research (2011Z01-1) ", and the subsidy of Nsfc Major research program integrated project (No:91215301).
Background technology
Navigation channel Slope Failure, landslide, avalanche are of common occurrence at home and abroad.At present, navigation channel bank slope generally adopts the form of structure of rigidity revetment to protect, but because Gravity Retaining Wall is from great, soft foundation needs process, cause costly and can cause the degeneration of river ecological environment, therefore bank slope ecological protection has become the new trend that bank protection work is built.How under the prerequisite meeting cruiseway navigation function, realizing the combination of bank protection structure durability and ecological property, is the difficult point and hot issue that face in ecological revetment Technique Popularizing.
Summary of the invention
In order to overcome the deficiency of existing traditional bank slope protection engineering, the invention provides a kind of reinforced earth lightweight revetment barricade utilizing the ecological mask of building-block, not only effectively can solve the collapse on the bank on riverbank, navigation channel, cave in and Gravity Retaining Wall from the great problem needing soft soil foundation etc., and improving in the Riparian Zone ecological functions reduction that conventional rigid shore protection causes and will play positive role.The present invention also will provide the construction method of this lightweight revetment barricade.
The technical solution adopted for the present invention to solve the technical problems is, the reinforced earth lightweight revetment barricade of the ecological mask of a kind of building-block, and its structure is:
On ground, be provided with successively from bottom to up: bottom geo-grid, hardcore bed, some layers roll " the geogrids reinforced earth layer " that fill stratum and top layer geo-grid or layering geo-grid are alternately formed;
With lateral surface (one side towards navigation channel) on described geogrids reinforced earth layer, be coated with comprehensively and fill with stone-laying barricade mask;
Described filling stone-laying barricade mask covers the part above geogrids reinforced earth layer, extends to the inner side spats (leaving the side in navigation channel) of this revetment barricade; Top layer geo-grid tiling stretch-draw in described geo-grid, is connected with this form anchor;
Described filling stone-laying barricade mask covers the part of geogrids reinforced earth layer lateral surface, extends downwardly into spats in ground;
Described filling stone-laying barricade mask covers the surface of geogrids reinforced earth layer lateral surface part, is provided with building-block layer;
In the building block hole of described building-block layer, be filled with excavation spoir, and plant herbaceous plant, form ecological revetment mask.
One of prioritization scheme is: the bottom surface kind outside revetment barricade is implanted with pilotage and the reed of wave that disappears, and forms vertical ecological mask, and opposing current scour, ship wave are corroded and prevent accidental ship collision etc.
Prioritization scheme of the present invention also has:
1, described " geogrids reinforced earth " refers to: the bottom in revetment barricade, top layer geo-grid or layering geogrids reinforced earth, the soil pressure that revetment barricade is suffered when low water stage can be balanced, with enhanced level to resistance to overturning, adjustment uneven settlement of foundation; The domatic geo-grid of revetment barricade can, as the flexible support face of filling with stone-laying, prevent its changing of the relative positions from ftractureing;
2, described " form anchor " refers to: for top layer geo-grid provides the concrete breast boards with reinforcing bar crotch of anchored force;
3, described " filling stone-laying " refers to: from levee toe up stone-laying perfusion mortar on the geo-grid as flexible support face, to make soil property revetment and the barricade mask thereof of design grade, prevent wave cut or water logging soil property revetment; Banket after building soil property revetment end face by laying bricks or stones, geo-grid is tiled stretch-draw, bankets and roll and fill with stone-laying, carry out soil property revetment end face clad;
4, described " building-block layer " refers to: filling with the mode according to fissure of displacement bond on stone-laying revetment barricade mask, from soil property revetment levee toe up staged build aperture building-block vertically upward by laying bricks or stones, or building-block aperture is against slope masonry;
5, described " ecological revetment mask " refers to: in building block hole, insert excavation spoir and be mixed into composite long-acting nutrient material, the herbaceous plant such as plantation vetiver, form ecological revetment mask, the vegetation planted can not give maintenance and can survive by natural rainfall.
In other words, the formation of the reinforced earth lightweight revetment barricade of the ecological mask of building-block of the present invention is: directly utilize original position to excavate the soil body, geo-grid and filling stone-laying clad, make reinforced earth revetment barricade; The flexible bearing surface of geo-grid makes filling stone-laying domatic, form the revetment barricade of face predetermined slope near water; Again filling stone pitching on from soil property revetment levee toe up staged build aperture building-block vertically upward by laying bricks or stones, or building-block aperture is against slope masonry, in building block hole, insert excavation spoir and be mixed into composite long-acting nutrient material, the herbaceous plant such as plantation vetiver.
Like this, reinforced earth lightweight revetment barricade is utilized to reduce sedimentation and the disposal cost of soft foundation, the lateral deformation of opposing bank slope; Rely on the ecological mask of building-block that reinforced earth lightweight revetment barricade is made, opposing collapse on the bank, current scour and ship wave erosion etc.; In the plantation pilotage of revetment barricade bottom surface and the unrestrained reed that disappears, form vertical ecological mask, opposing current scour, ship wave are corroded and prevent accidental ship collision etc.
The technical scheme completing the present application task is, the construction method of the reinforced earth lightweight revetment barricade of the ecological mask of above-mentioned building-block, and it is characterized in that, step is as follows,
