A kind of water conservancy that stability is good antiseepage protection ground

Technical field

The utility model relates to hydraulic engineering technical field, the good water conservancy of specially a kind of stability protects from ground with antiseepage Base.

Background technique

Hydraulic engineering is the surface water and groundwater for controlling and deploying 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, just can control water flow, prevents flood, and carry out water It adjusts and distributes, to meet people's lives and production to the needs of water resource, hydraulic engineering needs to build dam, dike, spillway, water Lock, water inlet, channel, the different types of hydraulic structure such as cross mortise, log chute, fish pass, to realize its target.

Traditional river antiseepage often first under the premise of meeting the functions such as river flood control, water drainage, water storage, focuses on The materials such as the cemented rock or concrete in river, composite geo-membrane carry out antiseepage protection design, seldom go to consider river and periphery The unification of history environment, social environment, ecological environment and humanistic environment causes underground water so that city river canalization is serious It can not exchange, many animals and plants, which are had nowhere live, to inhabit, and aquatic animal builds nest without place, and amphibian can not debark and look for Food, oviposition procreation are created great difficulties to their existence procreation, and many places only consider the flooding action in river, unilateral strong Riverbank hardening is adjusted, the relationship of soil and water body has been isolated, has separated water system mutually with soil and its biotic environment, breaks the natural river of ring The biological chain of stream, destroys ecological environment, so that the environment in river and surrounding after administering is not in tune, and the environment in river Condition pattern, and make biological species unification or aquatic animal frequency is made to face extinction, thus bring environmental problem is also quite tight Weight.

Utility model content

The purpose of this utility model is to provide a kind of antiseepages of stability good water conservancy to protect ground, and it is good to have stability The advantages of, solve the problems, such as that existing water conservancy antiseepage protection foundation stability is poor.

To achieve the above object, the utility model provides the following technical solutions: a kind of water conservancy that stability is good is anti-with antiseepage Ground, including ground are protected, offers sink at the top of the ground, the inner wall of the sink is fixedly connected with impervious barrier, described Impervious barrier is internally provided with protective layer, and the impervious barrier includes the first bentonite waterproof blanket, first bentonite waterproof blanket Surface be fixedly connected with cement soil layer, the protective layer includes the second bentonite waterproof blanket, second bentonite waterproof blanket Surface be fixedly connected with soil layer of being always or usually as specified, the surface of the element soil layer is fixedly connected with lattice guest's layer, first bentonite waterproof blanket Including nonwoven fabric layer, the surface of the nonwoven fabric layer is provided with bentonite bed, and the surface of the bentonite bed is provided with nonwoven fabric layer, The material of second bentonite waterproof blanket is identical as the first bentonite waterproof blanket.

Preferably, the bottom of the impervious barrier two sides is fixedly connected to concrete column, and the concrete column is internally provided with Stiffener, the quantity of the concrete column are several.

Preferably, the surface of the impervious barrier is every 30 meters of settings, one protective layer, and the protective layer is close to impervious barrier Side be fixedly connected with impervious barrier.
