Abstract

The utility model discloses an artificial reef device which comprises a reinforced concrete base and a plastic pipeline assembled on the base, wherein a plurality of through holes penetrating through two thick surfaces of the pipeline wall are distributed on the pipeline. Due to the fact that the reinforced concrete base is heavier than the plastic pipeline, the base can stably land on a seabed under the effect of gravity, and a reinforced concrete plate at the bottom of the base sinks into the seabed soil body to firmly seize the surface of the seabed. The artificial reef device can stay at a throw-in place stably even in extreme sea environments, so that damage, turnover, moving and sinking of the artificial reef device can not easily happen. The plastic pipeline is lighter so that the assembled artificial reef device can be easily moved and thrown into a fixed point on the seabed. The inside of the pipeline is hollow, and the plurality of through holes penetrating through two thick surfaces of the pipeline wall are distributed on the pipeline, so that water can freely flow inside and outside the pipeline, a good survival environment is created for fishes and shellfishes, and surrounding fishes and shellfishes can be attracted to gather around the artificial reef device to develop and breed.

Description

The artificial reef device

Technical field

The utility model relates to a kind ofly can improve the device of animal living enviroment under water such as fish and shellfish, particularly a kind of artificial reef device.

Background technology

Artificial reef can be used as the substitute of the natural reef that has damaged, can reduce the wave flow velocity, and then alleviates the infringement of wave to natural reef, and protection existing natural reef reaches the purpose of improving halobiontic living environment.

The kind of artificial reef is numerous, comprises shipwreck, junked-auto, junked tire, large-scale ironware, stone material and xoncrete structure etc.But the existing manual reef generally is directly arbitrarily to throw in the seabed, and than being easier to infringement, upset, moving and depression, what have is heavier again under extreme sea condition, and difficult is installed effort, needs to consume a large amount of manpower and materials.

In view of this, the above-mentioned defective further investigation to existing artificial reef has this case to produce then.

The utility model content

In view of this, the purpose of the utility model is to provide a kind of artificial reef device that can be stabilized in release position and rapid operation.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of artificial reef device comprises reinforced concrete plinth and is assembled in the plastic conduit on this pedestal, is distributed with the through hole on a plurality of through tube wall thickness two surfaces on this pipeline.

Said pedestal is to contract and U type groove that two ends connect the U type opening part that said pipeline is lain and is placed on pedestal in the U type opening.

Said pipeline is a pipe.

Said pedestal is provided with the through hole on through slot wall thickness two surfaces.

Said pipeline is bundled on the pedestal through the rope of tying up that passes said through hole.

After adopting said structure; The artificial reef device of the utility model has following beneficial effect: because reinforced concrete plinth is heavier than plastic conduit; Can steadily drop on the sea bed at the action of gravity bottom base; And the armoured concrete slab of base bottom sinks to and clenches the sea bed surface in the seabed soil, even the artificial reef device also can be stabilized in release position under extreme sea condition, is not prone to infringement, upset, moves and the phenomenon of depression; Plastic conduit is lighter, and the artificial reef device after the assembling is easier to move, fixes a point throw on sea bed like this; Pipe interior hollow; Also lay the through hole on a plurality of through tube wall thickness two surfaces on the tube wall of pipeline, make the current can free-flow inside and outside pipeline, for fish and shellfish have been created good living environment; Fish and shellfish around attracting accumulate in this, and grow breeding.

Embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

As depicted in figs. 1 and 2, the artificial reef device of the utility model comprises pipeline 1, pedestal 2 and ties up rope 3.

Pipeline 1 is pipe, the square tube that plastic inner hollow, two ends connect, and the cross section of pipeline 1 also can be rectangle, polygon or other shapes.A specific embodiment as the utility model; Pipeline 1 adopts pipe, and diameter is 1-2m, and length is 3-8m; Be rule or the irregular through hole 11 that is distributed with its thickness direction two surfaces of some perforations on the tube wall of pipeline 1, through hole 11 diameters are that 10-50cm does not wait.Through hole 11 serves many purposes, for example wear to tie up rope 3, lifting pipeline 1, make current can be pipeline 1 in free-flow play the effect of running water breed, biologies such as fish, shellfish are are freely come in and gone out through through hole 11 perch breeding etc. inside and outside the pipeline 1.

The U type groove that pedestal 2 contracts in the U type opening, two ends connect has 3 armoured concrete slabs, the U type opening part that pipeline 1 is lain and is placed on pedestal 2.Certainly pedestal 2 also can be arranged to the trapezoidal column that inner hollow, two ends connect, and has 4 armoured concrete slabs, is recessed into the cambered surface suitable with pipeline 1 under the end face of pedestal 2.The armoured concrete slab of pedestal 2 is provided with the through hole 21 on its thickness direction of some perforations two surfaces, ties up rope 3 and passes through hole 21 pipeline 1 is bundled on the pedestal 2, prevent stormy waves during pipeline 1 break away from pedestal 2.Pedestal 2 also can be as pipeline 1, and on the piece armoured concrete slab of pedestal 2, being rule or a plurality of diameters of irregular laying is the through hole 21 that 10-50cm does not wait.

Tie up rope 3 and can adopt that resistance to corrosion seawater is strong, the higher material of intensity, for example nylon rope etc.

The concrete assembling launch process of the utility model is following: at first utilize and tie up rope 3 and pipeline 1 is bundled in is assembled into the artificial reef device on the prefabricated pedestal 2, adopt ship that the artificial reef device is transported to the sea; Then hawser is located in the through hole 21 on the pedestal 2, utilizes crane on the ship will tie up at the artificial reef device on the hawser and throw in to sea bed, the diver assists to place.Because reinforced concrete plinth 2 is than plastic conduit 1 weight; Can steadily drop on the sea bed at action of gravity bottom base 2; And the armoured concrete slab of pedestal 2 bottoms sinks to and clenches the sea bed surface in the seabed soil, even the artificial reef device also is difficult for infringement, upset, moves and depression under extreme sea condition.

After implementing, the utility model has following remarkable result:

1, pipeline 1 inner hollow, two ends connect; Also lay a plurality of through holes 11 on the tube wall of pipeline 1, make the current can be, for fish and shellfish have been created good living environment in the inside and outside free-flow of pipeline 1; Fish and shellfish around attracting accumulate in this, and grow breeding;

2, utilize and to tie up rope 3 plastic conduit 1 is bundled on the reinforced concrete plinth 2,, make the artificial reef device can be stabilized in release position, be not prone to infringement, upset, mobile and depression phenomenon because pedestal 2 is heavier and floor space is bigger;

3, throw in the artificial reef device of setting size, quantity according to oceans such as place, waters, ecotope etc., can be fully, effectively utilize environment.

The product form and the style of the foregoing description and accompanying drawing and non-limiting the utility model, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
