Problems solved by technology

Theoretically, the limited quantified flood standard cannot solve the problem of engineering water damage caused by unlimited super-standard floods; embankments with earth-rock structures cannot resist super-standard floods
At present, there is also a lack of disaster prevention and mitigation design theory for auxiliary dam flood diversion of reservoirs and controllable flood diversion of special spillways

Embodiment 1

[0061] Example 1: Multi-stage self-breaking soil flood diversion dam protected by geosynthetics, which consists of: multi-stage self-breaking soil dike protected by geosynthetics 10, soil water-passing soil water-passing dyke 1, automatic water level gauge 3, slope protection 2, Trash rack 5, soil protection layer 9, non-woven cloth block stone sea man 14, combined figure 1 , 2 Description,

[0062] The slope protection 2 is set in the upstream anti-scouring range of the said soil over-water and over-water dyke 1, which is responsible for flood diversion and anti-scouring.

[0063] The automatic water level gauge 3 is laid on the upstream slope of the dyke 1 and plays the role of early warning and flood diversion.

[0064] A platform 4 is set up at the upstream end of the said soil over water and the soil over water dam 1,

[0065] The top of the weir of the dam 1 is connected to the geosynthetic protective surface 6-1 of the trapezoidal weir surface to control flood diversion and sco...

Embodiment 2

[0095] The multi-stage self-breaking soil flood diversion dam protected by the geosynthetic material described in Example 1, the soil water-passing dyke (1), the multi-stage self-breaking earth dike (10) protected by the geosynthetic material, and the rope-tie non-woven cloth belt ( 16) All are designed in accordance with the design theory of dam disaster prevention and mitigation. The dam disaster prevention and mitigation design theory is: on the basis of the existing design theory and specifications, increase the disaster prevention and mitigation design according to the flooding mechanism of the floodplain to avoid catastrophic dyke bursts. Regarding the flood diversion, the farmland is regarded as the flood discharge floodplain, and the irresistible excess flood is used for flood diversion to the floodplain and the farmland is controllable and dispersed. The excess flood refers to the flood standard specified by the specification or the project can The flood discharge mecha...

Embodiment 3

[0097] Example 1 The bottom width B of the geosynthetic material trapezoidal protective surface 6-1 is calculated using the following formula;

[0098]

[0099]

[0100] In the formula: B—— is the 6-1 bottom width B, m of the geosynthetic trapezoidal protective surface; Q—— is the flood diversion flow at the flood diversion point, m3 / s; η——the width coefficient of the 6-1 geosynthetic trapezoidal protective surface, m—— is the 6-1 discharge coefficient of the geosynthetic trapezoidal protective surface; σ—— is the 6-1 submergence coefficient of the geosynthetic trapezoidal protective surface; ε—— is the 6-1 side shrinkage coefficient of the geosynthetic trapezoidal protective surface; g —— is the acceleration of gravity, m2 / s; H 0 —— is the geosynthetic material trapezoidal protective surface including the head of the traveling velocity. 6-1 The head on the weir, m, H—— is the geosynthetic material trapezoidal protective surface. 6-1 The head on the weir, m, v 0 —— is the head of ...

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

Technical field: [0001] The present invention belongs to the technical field of flood diversion projects for dams and dams, and relates to a multi-stage self-collapsing soil flood diversion dam protected by geosynthetics. Background technique: [0002] In 2013, Heilongjiang experienced floods beyond the standard that could not be withstood by manpower. Under the existing water conservancy norms and technical conditions, it is very difficult to achieve the flood prevention plan of "ensure the safety of flood fighting and rescue troops" and the safety of dams. If innovative theories, Innovative methods to achieve this goal have also solved the worldwide problem of over-standard flooding of dams, injuring people and destroying things. [0003] Difficulties faced by dykes with over-standard floods: When river dykes generally reach the standard, floods will flow into the river course, increasing the probability of flooding downstream. The height of the dyke will increase the amount of w...
