Abstract

The utility model relates to a fish nest building block used for the construction of a river ecological project. The building block is suitable for water ecological construction projects such as water conservancy and gardens, and particularly for the ecological project construction in rivers in a plain dense waterway net region short of building stones. The cubic building block has three holes and is made through prefabricated concrete pouring; during installing the building blocks, the holes arranged on the blocks are aligned and communicated; after a shore protection engineering is finished, the inside of a wall body of the engineering is formed into a space communicated vertically and horizontally, thus, an artificial nest is built for aquatic fishes, shrimps and shellfishes; moreover, the utility model avoids the damage on ecological environment caused by engineering construction and meets the requirements of people for river bank ecological diversity.

Description

The building block of fish nest

1, technical field:

The utility model is a kind of fish nest building block that the river channel ecology bank protection work is built that is used for, adopt the building block of the utility model fish nest to construct the river channel ecology landscape engineering, can satisfy the requirement of ecological constructions such as river course, lake, channel, pond, be applicable to the waters ecological engineering in water conservancy, gardens.

2, background technology:

At present; common channel revetment engineering is to adopt the method for stone-laying or Cast-in-place concrete to form retaining wall; waters and land are separated fully; although it is in the behavior of constraint water; the engineering effect has been brought into play in the aspect that prevents erosion; but; to the protection water area ecological environment and keep the people and water environment harmonious aspect influence bigger; conventional engineering method; changed original natural water front in river course and river slope structure fully; river course bank slope face has been taked the form of sealing; various aquatic animals and plants are difficult to growth on hard structure is domatic; the aquatic animal of river bank; water loving plant and microorganism have lost the environment of depending on for existence; be difficult to survive; therefore the living space of whole ecological system and food chain are just because of the hard engineering structures of one deck disconnects, and therefore ecological environment has suffered destruction, especially aquatic fish living environment is caused very big destruction.

3, summary of the invention:

In order to overcome the existing waterway stone-laying, the concrete bank protection work is to the influence of ecological environment, the utility model provides a kind of employing to have three holes, positive cubic shape, the building block that plain concrete is built, when building block is installed, piece is aimed at the cavity between the piece, connect, after being built into bank protection work, in the engineering body of wall, form the space that is communicated with up and down, for the fishes and shrimps shellfish in the water builds up artificial nest, this engineering body that has fish nest structure, avoided the destruction of engineering construction to a certain extent, satisfied the requirement of people the banco ecological diversity to ecological environment.And this prefabricated concrete block structure is simple, highly versatile, help batch production production again, can guarantee workmanship, can shorten the construction period, reduce engineering cost, be particularly suitable for lacking the ecological engineering construction in the little river course, dense waterway net region rural area, Plain of building stones resource.

The technical scheme that its technical problem that solves the utility model adopts is: (1) prefabricated concrete building block: be to have building block three holes, cubic shape, that plain concrete is built, three holes are that " fourth " font distributes.(2) the concrete piece is built by laying bricks or stones: according to the needs of actual riverbank height, layering is built by laying bricks or stones, building block with one deck will interconnect, and the part building block will allow the upstream face of hole and engineering connect, become the import and the outlet of fishes and shrimps, between layer and the layer, also will arrange the part building block to be interconnected, expansion fish nest inner space increases complexity.

The utility model technology beneficial effect is: when river training works is built, build artificial fish nest in conjunction with bank protection work, the living space of protection bank, waters fishes and shrimps reduces engineering construction as much as possible to the influence that environment brings, and avoids environmental disruption; Simultaneously, the utility model is simple in structure, be easy to make, and helps batch production production, and quality is more prone to control, and construction costs is cheaper again.

5, the specific embodiment:

(1) mode of production of the utility model fish nest building block: the utility model building block is building block cube shaped, three holes, that plain concrete is built, and three holes are that " fourth " font distributes.At first to make mould according to the utility model block structure characteristics, be divided into external mold and hole internal mold, external mold is positive cubic shape, end face and bottom surface opening, shape aperture, garden is offered in the side, be used to install horizontal internal mold, internal mold is divided into half high garden shape internal mold of horizontal garden tubular internal mold and vertical direction again.Next is that order according to " internal mold of external mold-laterally-vertically internal mold " installs mould.Can the on-the-spot demoulding after concrete is cast, form removal is " vertically-laterally internal mold internal mold-external mold " in proper order.Behind concrete curing, make blockwork, promptly can be used for going in the river engineering.(see figure 1)

(2) the concrete piece is built by laying bricks or stones: can select individual layer to build by laying bricks or stones with multilayer according to actual requirement of engineering and build by laying bricks or stones, building block with one deck will interconnect, and the part building block will allow the upstream face of hole and engineering connect, become the import and the outlet (see figure 6) of fishes and shrimps, between layer and the layer, also will arrange the part building block to be interconnected, expansion fish nest inner space increases complexity.

(3) Fig. 6 and Fig. 7 are that this novel practical is in the channel revetment application in engineering, it is above to the following position of ordinary water level to be installed in foundation slab, in this example, the employing individual layer is installed, in the building block of upstream face side, indivedual building block holes are guaranteed to be communicated with water body towards the river course, inner hole is interconnected, and forms labyrinth type fish nest.

Claims

1. fish nest building block is characterized in that: have prefabricated concrete building block three holes, the regular cube shape, three holes are the distribution of " fourth " font and are interconnected.

2. fish nest according to claim 1 building block, it is characterized in that: can select individual layer to build by laying bricks or stones according to actual requirement of engineering and build by laying bricks or stones with multilayer, building block hole with one deck will interconnect, and the part building block will allow the upstream face of hole and engineering connect, and becomes the import and the outlet of fishes and shrimps; Between layer and the layer, arrange the part building block to be interconnected, expansion fish nest inner space increases complexity.
