Background
The slope protection refers to the collective name of various paving and planting on the slope surface for preventing the slope from being washed. The river reach where the bridge site is located is flushed by water flow year by year, so that the river bank is continuously collapsed. In order to protect bridge and embankment, a protective building is built on the concave bank. In addition, when the river bank is washed to endanger farmlands and villages due to the change of the river water flow direction caused by bridge establishment, a protective building is also required to be built on the river bank.
The slope protection function can be divided into two kinds: the slope protector is only a slope protector resistant to wind and scouring, does not bear lateral soil pressure, such as a spray soil slope protection, a grid plant slope protection, a plant slope protection and the like, and is only suitable for a gentle and stable slope without sliding. And (II) providing anti-slip force for retaining slope protection.
