Embodiment 1

[0036] Example 1, such as figure 1 As shown in the content, for the rivers and lakes to be treated, the foundation 9 is treated and reinforced and the foundation is cleaned and leveled according to the design requirements. The slope foot on the water side adopts riprap (or block stones, gabion net, etc.) to protect the foot 1. On a good foundation 9, fill large rivers and lakes layer by layer, clean up the bottom mud and fill the bag. 3 Embankment structure. The slope surface of the embankment structure shall be covered with geocells or gabion nets to protect the surface 4 and vegetation nets 6 shall be planted. Reinforcement 5 fixes the geocell or gabion mat cover 4 on the large filling bag 3 the dyke body structure, the backside slope of the dyke body structure is directly planted with vegetation, and the water area of ​​the river and lake ecological dike structure is planted with reeds and other aquatic plants 2 , Planting local shrubs or saplings and other plants 8 on the sl...

Embodiment 2

[0037] Example 2, such as figure 2 As shown in the content, for the reconstruction or transformation of the waterway, the foundation 19 treatment and reinforcement and foundation cleaning and leveling are completed in accordance with the design requirements, and foundation protection structures such as wooden piles and prestressed pipe piles are built in the front of the bank protection. The water side of the bank protection uses a stone cage foundation Foot protection and upright retaining wall 11, planting creeper and other plants 13 and reeds and other aquatic plants 12 on the top and different heights of the gabion foundation and upright retaining wall 11 for ecological protection. The upright retaining wall 11 at the front of the revetment can be used as a ship to dock For temporary berths, fill large rivers and lakes layer by layer on the cleaned and leveled foundation 19, clean the bottom mud, fill the bag, and embankment body 14 revetment structure. At different heights...

Abstract

The invention provides a large filling bag ecological embankment and revetment building method for a river lake channel. The method comprises the steps that (1), on the basis of cleaning and leveling, an embankment structure is filled with cleaned river lake bottom mud layer by layer through the large filling bag technology until the embankment structure reaches up to a designed elevation of the embankment top and the height of 0.5-1 m beyond the designed elevation is reserved through filling construction; (2), the cleaned river lake bottom mud is filled through a land pump, or special complete equipment and corresponding construction technologies are adopted to directly conduct mechanical paving and filling, and then the filled cleaned river lake bottom mud is sewn into bags; and (3), filling soil materials of the large geotextile filling bag embankment structure are taken from local resources, the bottom mud obtained through river lake regulation and channel excavation and cleaning is used as the filling soil materials, the initial water content of the filling soil materials is controlled within the range from 50%-80%, and the large filling bag embankment structure which is layered appropriately is adopted according to the practical situation. According to the method, the design is reasonable, the process is simple, construction is easy, operation is convenient, cost is low, popularization is easy, the ecological functions are good, and the method is applicable to ecological management and ecological channel construction of river lakes in soft soil areas.

Description

Technical field [0001] The invention belongs to the technical field of embankment and bank protection construction for water conservancy and water transportation projects, and specifically relates to a novel structure and construction method for ecological dike and bank protection in river and lake governance and waterway construction, and is suitable for river and lake ecological governance and ecology under soil bank slope conditions Waterway construction. [0002] The present invention has been awarded by the Ministry of Water Resources' public welfare industry scientific research special project "Western Small and Medium-sized Rivers and Bank Slope Ecological Control Complete Technology Research (201301022)", Jiangsu Province Transportation Science Research Project "Danjin Licao River Channel Improvement (Danjin Ship Lock) Project Supported by "Research on Ecological Restoration Technology of Waterway Soil Bank Slope (2011Z01-1)". Background technique [0003] Most of the rive...
