Description

Technical Field

[0001] The present invention relates to a levee slope protection structure, in particular to an assembled levee structure and an assembly method thereof, and belongs to the technical field of levee engineering. Background Art

[0002] In urban planning and construction, flood control dams are an important component. They not only have the function of flood control, but also take into account the role of urban greening in regulating ecological balance. At present, common flood control landscape dam structures include: pile-wall combination structure, earth-stone structure and prefabricated block structure. Among them, the pile-wall combination structure has been widely recognized by construction units due to its advantages such as fast construction speed, low cost, less impact on the surrounding environment, strong durability, and no need for later maintenance. However, the sheet pile structure has a convex tenon on one side and a groove on the other side. When in use, several sheet piles bite each other to form a pile-wall combination structure. However, this sheet pile combination structure is very easy to cause extrusion and deflection when it is driven into construction, so the construction is difficult and the construction cost is also high. Prefabricated block structures generally use cast-in-place blocks, which have the advantage of good wind and wave resistance and are on-site cast-in-place structures. However, the process is relatively complicated. Under the influence of climate, wind and waves, the construction quality is difficult to guarantee, the construction speed is slow, and the work efficiency is low. In addition, there is a shortage of stone materials in many areas, which cannot be reused in the later stage, and are difficult to reinforce or demolish. After construction, as the embankment settles, it is easy to become detached from the slope, posing a safety hazard. Summary of the invention

Through improvements in structural design, the elevation and length of the dam are increased by increasing the number of components, and the number of spiral piles and the strength and number of columns, beams and plates can be adjusted to adapt to different application environments.
