Abstract

Disclosed is a multistage self-bursting soil flood diversion dam protected through geosynthetic materials. According to the multistage self-bursting soil flood diversion dam protected through the geosynthetic materials, a slope protection (2) is arranged within the upstream scouring protection range of a soil water passing dam (1), and an automatic water level indicator (3) is arranged on an upstream slope of the soil water passing dam (1); a platform (4) is laid at the upstream end of the soil water passing dam (1), and the weir crest of the soil water passing dam (1) is connected with a trapezoidal weir surface geosynthetic material protection surface (6-1); a downstream slope of the soil water passing dam (1) is connected with a trapezoidal discharge chute geosynthetic material protection surface (6-2); a rope-tied non-woven fabric threading fixing foot (8) is arranged at the bottom of a downstream slope foot of the soil water passing dam (1); and a fixing body I (7-1) is arranged at the bottom of the upstream end of the trapezoidal weir surface geosynthetic material protection surface (6-1), and a fixing body II (7-2) is arranged at the bottom of the downstream end of the trapezoidal weir surface geosynthetic material protection surface (6-1). The multistage self-bursting soil flood diversion dam is used for flood diversion of the soil dam.

Description

[0001] Technical field:

[0002] The invention belongs to the technical field of dam flood diversion and conservancy engineering, and relates to a multi-level self-bursting soil flood diversion dam protected by geosynthetic materials.

[0003] Background technique:

[0004] In 2013, there was a flood beyond the standard in Heilongjiang that manpower could not resist. Under the existing water conservancy regulations and technical conditions, it is very difficult to realize the flood control plan of "ensure the safety of flood fighting and rescue troops" and the safety of dams. The innovative method to achieve this goal also solves the worldwide problem of the over-the-top flood of dams breaking down and causing damage to people and property.

[0005] Difficulties faced by dams that exceed standard floods: When rivers and dams are generally up to standard, floodwaters will flow into the river, increasing the probability of downstream floods, increasing the height of the dam, and ...
