Abstract
The invention provides a security step embankment. The security step embankment comprises a bank foundation. Continuous steps are formed on the side, facing a water body, of the bank foundation. Vertical slideways are vertically and downwards formed in the step faces of three or more continuous steps. A guardrail capable of ascending and descending is arranged in each slideway in a matched mode. Gaps are formed between the outer surfaces of the guiderails and the corresponding vertical slideways. The average density of each whole guardrail is less than 0.5 g/cm3, and therefore the guardrails can float in the water. After the vertical slideways are filled with water, the guardrails float upwards. After the water in the vertical slideways are discharged, the guardrails fall into the vertical slideways. The lower end of the vertical slideway of the lowest step with the vertical slideway extends downwards to a riverbed and directly communicates with the riverbed. The vertical slideways of the other steps can directly or indirectly communicate with the riverbed. The protective positions of the guardrails of the security step embankment can automatically change along with the changes of the height of the water level, so that the security step embankment keeps a high security protective state all the time.
