Multi-stage self-bursting geosynthetic material earth-rockfill emergency spillway

Abstract

The invention discloses a multi-stage self-bursting geosynthetic material earth-rockfill emergency spillway and belongs to the hydraulic engineering of emergency spillway engineering. Emergency spillway controllable flood diversion is achieved, disastrous dam breaking surge is avoided, and people and livestock have the escape chance through flood diversion when encountering over-standard flood. The multi-stage self-bursting geosynthetic material earth-rockfill emergency spillway is mainly characterized in that the top of an over-water earth dam (2) is connected with a geosynthetic material scale-shaped protective face (4), the upstream side of the geosynthetic material scale-shaped protective face (4) is connected with a trash rack (3), the top of the geosynthetic material scale-shaped protective face (4) is connected with a protective earth layer (6), the downstream side of the top of the over-water earth dam (2) is provided with a geosynthetic material protective multi-stage self-bursting earth dam (5), and the geosynthetic material scale-shaped middle protective face is formed in the mode that rope-tied non-woven fabric penetrates through scale-shaped units (IV). The multi-stage self-bursting geosynthetic material earth-rockfill emergency spillway is applicable to reservoir auxiliary dam, main dam, high dike, high headwork barrage emergency floor diversion, is simple in structure, convenient to implement, low in manufacturing cost, safe and reliable, and does not occupy land all the time.

Description

technical field

[0001] The invention belongs to the technical field of spillway water conservancy engineering, and in particular relates to a multi-stage self-collapsing geosynthetic earth-rock spillway. Background technique

[0002] On September 10, 2015, an embankment burst occurred in Japan, and entire houses and rows of vehicles were washed away, causing many casualties and missing, and a large amount of property loss. Once the reservoir dam is flooded, it will be a catastrophe. The case of the catastrophe and the huge economic loss that destroys generation shows that solving the super-standard flood dam water damage is a technical problem that needs to be solved urgently to ensure the national economy and the people's livelihood, and illustrates that the present invention will produce huge social and economic benefits.

[0003] The case of a reservoir dam break shows that large dam break surges will destroy reservoirs, bridges, canal heads, embankments, houses, etc. in ...

specific Embodiment approach

[0033] Specific embodiments: the best embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings (see figure 1 , figure 2 , image 3 , Figure 4 )

[0034] Embodiment: The top of the overwater earth dam 2 is connected with a fish-scale-shaped protective surface 4 of geosynthetic material to prevent the over-standard flood diversion from scouring the over-water dam. The top of the protective surface 4 is connected to the protective soil layer 6 to prevent the geosynthetics from being damaged by ultraviolet radiation. The upstream side of the fish scale-shaped head protective surface 4-1 of the geosynthetics is connected to the trash rack 3 to prevent floating objects from damaging the synthetic materials. Fish scale face protection, geosynthetic material Fish scale head protection 4-1 The top downstream side is connected with geosynthetic material protection Multi-level self-collapsing earth embankment 5, automatic co...
