Technical Field
[0001] This utility model belongs to the field of slope protection technology, specifically relating to a reinforced soil revetment composite structure suitable for soft soil foundations. Background Technology
[0002] Seawalls are engineering measures that artificially reinforce existing coastal slopes to protect against wave and current erosion, as well as groundwater action, and to maintain shoreline stability. Seawall construction is similar to seawalls, and based on their outer slope, they can be classified as sloping seawalls, steep-wall seawalls (including vertical ones), and seawalls combining both.

[0008] Backfill soil, said backfill soil is placed on the wall panel at one end away from the river channel;
[0009] Multiple tie rods are provided within the backfill soil; one end of each tie rod is connected to the wall panel, and the other end is inserted into the backfill soil.
[0010] Furthermore, an impermeable geotextile is provided between the wall panel and the backfill soil.
[0011] Furthermore, the foundation includes a concrete cushion layer and a plurality of wooden piles; the plurality of wooden piles are inserted into the soft soil foundation; the concrete cushion layer is poured on top of the wooden piles.

[0013] Furthermore, the upper and lower adjacent blind pipes are stacked and staggered, and connected by the steel bars.
[0014] Furthermore, a drainage blind pipe is installed on the wall panel located above the water level; the drainage blind pipe is located at one end of the wall panel near the river channel; a first subspace and a second subspace are relatively independently arranged within the drainage blind pipe; the first subspace is located at the end near the river channel; the second subspace is located at the end near the backfill soil; the first subspace is filled with grass seed soil, and the second subspace is filled with clay to form a plant growth surface for the bank protection structure.
[0015] Furthermore, multiple tie bars are longitudinally spaced within the backfill soil; a crushed stone geogrid is installed within the backfill soil for reverse anchoring; the crushed stone geogrid reverse anchoring is installed between two longitudinally adjacent tie bars.
[0016] Beneficial effects:
[0017] This utility model provides a reinforced soil revetment composite structure suitable for soft soil foundations. When applied to soft soil foundations, the stepped stacked wall panels provide better stability. Furthermore, the porous structure on the surface of the drainage blind pipes provides a channel for plants inside the blind pipes to grow outward from the wall panels. At the same time, the porous structure also facilitates the timely drainage of water behind the wall, ensuring that the water in the soft soil foundation can be drained in time and reducing the impact of water pressure on the revetment composite structure.
