Description

A greenway system built on soft foundation permeable embankment stems and its construction method

Technical field

Background technique

With the expansion of urban construction scale, urban flood control standards continue to improve, which places higher requirements on flood control embankments in terms of flood control security, ecological water affinity, convenient transportation, soil and water conservation, ecological restoration, and environmental protection.

Most of the river embankments, lake embankments and polder embankments in the plain river and lake areas were built in the 1950s. They were built for the development and utilization of rivers and lakes and the continuous reclamation of lakes for farmland. The embankment base is a thick layer (3-10m) of alluvial deposits. The embankment body is made of silt soil and is filled with artificial soil. The fill quality is poor. Dangerous situations have occurred frequently during flood seasons over the years. The embankment body is seriously soaked. Some sections of the embankment have faced wave ridges, landslides and landslides on the backwater side of the embankment. Condition.

To reinforce and transform the existing soft-foundation permeable embankments of rivers and lakes, it is first necessary to ensure that the soft soil foundation does not slip deep during the construction period and during operation after completion. Secondly, it is necessary to ensure that the embankment body can retain water normally when the water level of rivers and lakes is high, and does not Penetration deformation occurs. During construction, it is necessary to avoid encroaching on water volume outside the embankment, and to reduce land acquisition and relocation inside the embankment. After completion, it is necessary to meet the needs of citizens for transportation and water-related activities, and to achieve an organic integration of waterfront landscape and urban balconies, so that the embankment has flood control, security, and ecological It has multiple functions such as being close to water, convenient transportation, water and soil conservation, ecological restoration, and environmental protection.

The general soft foundation treatment methods for embankments include soil replacement method, drainage consolidation method, gravel pile method or cement-soil composite foundation, etc. All of them require the excavation of the existing soil embankment, which will cause great disturbance to the embankment body; Filling a large amount of earth and stone materials on the water side for footing and weighing will occupy a lot of lake volume; or increasing the foundation area by retreating the embankment shoreline to the backwater side, building sub-embankments, etc., which will require the acquisition of more land; the above methods all involve the current situation Large-scale reconstruction of embankments has poor soil and water conservation effects, long construction period, and high construction costs. At the same time, the general embankment body only has the single function of retaining water, and it is necessary to further explore the type of embankment reinforcement and transformation suitable for this condition.
