Abstract

The utility model provides an enclosure used for lake test and is characterized in that the enclosure is a two-layer circular bamboo pile-type enclosure which comprises inner ring bamboo piles and outer ring bamboo piles, a sun-shading net and a fishing net bonded with the inner ring bamboo piles, and a bamboo screen bonded with the outer ring bamboo piles, wherein the inner and the outer ring bamboo piles are spaced at a certain distance and fixed at the bottom of the lake with circular arrangement; and an insulating ring is arranged between the inner and the outer ring bamboo piles and formed by floaters and oxford fabrics. The enclosure can effectively stand against wind/wave shock and can prevent the algae from entering the test area from the outer side of the enclosure without complete isolation of the water body.

Description

A kind of lake test enclosure

Technical field

The utility model relates to a kind of water body isolated column, and enclosure is used in the test of particularly a kind of lake, belongs to the environment remediation test facilities, is particularly useful for the lake scientific experimentation and uses.

Background technology

Along with the attention of people to environment, increasing scientific research institutions are devoted to study the processing method of lake water correction.When medium scale application test is carried out in these scientific experimentations, a slice waters of relative closure need be crossed in the water body in lake so that carry out contrast test under the equivalent environment.In more existing reports: the test in the lake generally adopts polyvinyl chloride (colour bar cloth) to cross several square metres small cylindrical water body, and if when crossing area more than 1,000 square metres, because the stormy waves in the lake is bigger, can form impact force to enclosure, not only can tear polyvinyl chloride colour bar cloth, destroy the enclosure Experimental Area, also can make the test miscarriage.Therefore, be eager to seek a kind of effective enclosure construction method, this simple method just can not have been used.

The utility model content

The purpose of this utility model: aim to provide a kind of enclosure device of in the lake, building, carry out scientific experimentation with the water body that constructs a slice relative closure.

This lake test enclosure, it is characterized in that: it is to keep at a certain distance away, be fixed on the inside and outside circle bamboo stake that lakebed and round are arranged by two-layer, and the sunshade net, the fishing net that combine with the stake of inner ring bamboo, the bamboo paper tinsel that combines with outer ring bamboo stake constitutes inside and outside two circle bamboo stake type enclosures, and is provided with the cage ring that a circle is made of float and cloth Oxford between described two enclosures.

The stake of described inside and outside circle bamboo is respectively by being arranged on perpendicular to the affixed makeup ring round of the horizontal connecting rod of pile body.

The bamboo stake of described outer ring is provided with the bamboo paper tinsel that bamboo chip is woven into.

The inside and outside both sides of described inner ring bamboo stake are respectively equipped with sunshade net and fishing net.

Described described float constitutes through the oxford parcel, and the base of the oxford that it extends is downwards connecting on the gabion that sinks to lakebed.

Use enclosure according to this lake test that above technical scheme proposes, have simple in structurely, easy to use, the while also has certain fastness, for carrying out the environment contrastive detection at natural lake and the related scientific research activity provides technical support.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

This lake test enclosure, it is characterized in that: it is to keep at a certain distance away, be fixed on the inside and outside circle bamboo stake 2.1,2.2 that lakebed and round are arranged by two-layer, and the sunshade net 5, the fishing net 6 that combine with inner ring bamboo stake 2.1, the bamboo paper tinsel 3 that combines with outer ring bamboo stake 2.2 constitutes inside and outside two circle bamboo stake type enclosures, and is provided with the cage ring that a circle is made of float 4 and oxford 8 between described two enclosures.The stake of described inside and outside circle bamboo is respectively by being arranged on perpendicular to the affixed makeup ring round of the horizontal connecting rod of pile body.

The inside and outside both sides of described inner ring bamboo stake are respectively equipped with sunshade net and fishing net; The periphyton that sunshade is adhered on the net can be tackled the unscrupulous enclosure water body that enters of wawter bloom algae.

At first be ready to material: constitute i.e. bamboo stake (perpendicular, horizontal network), bamboo plate, oxford, fishnet, sunshade net, float, gabion, rope and steel wire by 9 kinds of main materials.

Choose pile spacing according to the stormy waves situation then: if zone of living in, lake often is subjected to typhoon influence, stormy waves is bigger, does not collapse for guaranteeing enclosure, and single bamboo pile spacing is designed to 0.5-1.0m.The enclosure height according to the decision of SEA LEVEL VARIATION and stormy waves, when stormy waves was 0.5 meter, the top design of enclosure exceeded 1 meter of the water surface, 1.0 meters at the hard end of lakebed, squeezed in the bamboo stake.The diameter of bamboo stake is 10cm, and fishnet 6 design heights are for exceeding about water surface 60cm, and about the high 60cm of the sunshade net 5 aspect ratio waters surface, oxford width (water surface is with the lower part) is about 1.5 times of enclosure water depth.

Construction process: earlier according to 5 meters at interval on inside and outside circle, play inside and outside two circle bamboo stakes at lakebed, the spacing of bamboo stake is 1.0 meters, binds horizontal connecting rod 1 then in the above, next colligation bamboo paper tinsel 3 in outer ring bamboo stake 2.2, colligation fixed net 6 and sunshade net 5 in inner ring bamboo stake 2.1.The oxford 8 of water body inside and outside rising in the middle of fishing net 6 and the sunshade net 5 isolated, at the fixing float of being made by foamed plastics 4 of an end of oxford, the other end is bound gabion 9, renders between inside and outside two row bamboo stakes.Oxford that enclosure is used and fishnet 6, sunshade net 5 bottoms all should be wrapped up gabion 9, and be treaded at the bottom of the mud.

The inside and outside bamboo stake of the two rows wave that plays a part to disappear during use, and middle oxford plays the effect of Lake Water Body A outside the trial zone B and enclosure in the enclosure that cuts off.When fluctuation of water table, because the buoyancy of the float 4 that foamed plastics is done, oxford can rise thereupon or descend, all the time play the effect of isolating the Internal and external cycle water body, fishnet 6 can prevent that the biology in the trial zone from escaping from or the biology in outer lake enters the trial zone, and sunshade net 5 can stop that the algae of outside water body enters the trial zone.

The result that the utility model uses in the comprehensive detection test in Microcystins in The Dianshan Lake indicates that this enclosure structure Design is feasible, has certain dissemination.
