[0002] River bank protection is widely used in water conservancy projects and river management. It is an engineering measure to protect river banks from water flow and erosion. Traditional river bank protection types mainly include mortar masonry and dry masonry blocks, groynes, sinking rafts, geotextile sandbags, etc. Its function is mainly to maintain the structural stability of the bank slope and prevent landslides caused by floods, and its effect is relatively good.

[0003] However, these types of protection are relatively expensive, difficult to construct and maintain, and have poor ecological and landscape effects. In recent years, new types of bank slope protection have emerged. The present invention is a new type of river bank protection structure based on the use of renewable materials such as logs, bamboo strips and geotextiles. Utility Model Content

It can be used to build new embankments or reinforce the river bank foot of old embankments to prevent water erosion and scouring.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a river bank protection structure composed of pine piles, bamboo strips and geotextiles, comprising a pine pile body, the pine pile body being installed at a river bank position on one side of the river, there being a stratum on one side of the river bank, the pine pile bodies being linearly distributed and arranged in a plurality inside the stratum, a plurality of bamboo strip grids and a geotextile body being sequentially distributed on one side of the pine pile body, the outer walls of the pine pile body, the bamboo strip grid and the geotextile body being all provided with full-length cross bars and binding wires for binding and fixing to form an upright retaining structure.

[0006] Furthermore, the bamboo grille includes a plurality of transverse bamboo strips, the outer walls of the plurality of transverse bamboo strips are provided with a plurality of vertical bamboo strips to form a skeleton, the main overlaps of the transverse bamboo strips and the vertical bamboo strips are connected with bolts, and the remaining grid members are connected with hemp ropes, and the outer walls of the transverse bamboo strips and the vertical bamboo strips are coated with at least three layers of anti-corrosion coating.

[0007] Furthermore, the back side of the geotextile body is filled with embankment soil and compacted to form an embankment slope shape, and grass is planted on the embankment soil to form a complete embankment and bank protection project.

[0008] Furthermore, the full-length cross bar and the outer wall of the above-ground part of the pine pile body are both coated with an anti-corrosion coating.

[0009] The utility model has the following beneficial effects:

[0010] 1. In the utility model, the pinewood pile body is driven into the foundation to a certain depth, and is fixed to the bamboo grid and geotextile body behind it by two upper and lower through-length cross bars, thereby enhancing the strength and integrity of the bank protection structure.

[0011] 2. In the utility model, after the above-mentioned structure is used for bank protection and embankment construction, since the pine pile body, bamboo grid and geotextile body are all made of flexible materials, the overall structure can better adapt to the pressure deformation caused by the soil on one side and the water pressure on the other side.

[0012] 3. In the utility model, the pine wood pile body and the bamboo grille are easy to obtain and cheaper than other bank protection types such as stone masonry, bank cages, concrete wave piles, etc., and have a price advantage for small and medium-sized river bank protection with low investment.
