Abstract
The invention discloses a kind of hydraulic engineering flood discharge antiseepage dam, including first layer supporting layer, second layer non cohesire soil layer, third layer corrosion-resistant coating, the 4th layer concrete structure sheaf, layer 5 membrane waterproofing and observation flood discharge hole；The present invention is by setting five-layer structure, second layer non cohesire soil layer especially therein, third layer corrosion-resistant coating and layer 5 membrane waterproofing, it can be good at playing the resistance to compression of dam, durable, anti-blend etch-proof effect, and between five layers by the special rattan after chemically treated into latticed through connection, each layer can be connected as to an entirety, to enhance the fastness of dam and stability；Setting observation flood discharge hole can timely observe the situation of sampling water, and automatic controlling gate flexibly can accurately carry out flood discharge, alleviate the pressure of dam, and then increase the service life of dam.
Description
Technical field
The present invention relates to Water Resources Domain, more specifically to a kind of hydraulic engineering flood discharge antiseepage dam.
Background technology
Hydraulic engineering is the surface water and groundwater for controlling and allocating nature, reaches and removes the evil emerging sharp purpose and build
Engineering.Also referred to as Hydraulic Projects.Water is human being's production and essential precious resources of living, but the state of its naturally occurring is simultaneously
Not in full conformity with the needs of the mankind.Hydraulic engineering is only built, flow could be controlled, prevents flood, and carry out water
It adjusts and distributes, to meet the needs of people's lives and production to water resource.Hydraulic engineering needs to build dam, dike, spillway, water
Lock, channel, crosses the different types of hydraulic structure such as mortise, log chute, fish pass at water inlet, to realize its target.
Hydraulic engineering not only makes a difference to the economy of location and society by its construction task, and to rivers,
Lake and natural appearance in the neighbourhood, ecological environment, natural landscape or even to regional climate, will all generate different degrees of
Influence.It is this to influence both advantageous and disadvantageous, this influence must be fully estimated during planning and designing, give full play to hydraulic engineering
Positive effect, eliminate its negative influence.
Dam is block rivers ditch water flow with raising of water level or the water retaining structure of adjusting flow.Reservoir can be formed, is lifted
High water level, concentrates head at regulated flow, for flood control, water supply, irrigation, hydroelectric generation, improves shipping etc..
Traditional dam is mostly earth and rockfill dam or concrete dam, since dam body is washed away by flowing water, corrodes or mixed for a long time
The reasons such as solidifying soil aging, can cause hypertonia, seepage discharge big and cause dam deformation, more serious to cause to have an accident.And
After long-time service, since the variation washed away with geology of flow will appear the offset of two dam bodys in left and right.
Existing part dam structure is simple, and antiseepage, Corrosion Protection are poor；And when variation in water pressure is excessive cannot and
When effectively observe with flood discharge depressurize, be easy to cause dam break.
