Summary of the invention
The object of the invention is the installation method that a kind of large-scale culture pure seine used in shallow sea is provided to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the installation method of a kind of large-scale culture pure seine used in shallow sea designed by the present invention,
Its concrete installation steps are as follows:
Before a, high tide, whole Culture pure seine is moved on seashore, and etting is collapsed configuration;
After b, high tide, the whole Culture pure seine in previous step a is moved to the default breeding-ground of Deepwater Open Sea by buoyancy, and by the float layer of Culture pure seine with the default stake in seabed or/and preset anchor be connected by rope;
C, after previous step b completes, carry out gradation again and launch etting, height after etting launches first is greater than the level of ebb tide of default breeding-ground, and is less than its flood tide water level, and the height of described level of ebb tide and flood tide water level is all for benchmark with the sea bottom surface of default breeding-ground;
At ebb tide, in previous step c, the sinker of Culture pure seine is gently down on sea bottom surface because conducting oneself with dignity, or even is directly trapped in bottom silt for d, seawater;
The etting of Culture pure seine in previous step d again at the incoming tide, launches, net by e, seawater completely
Height after clothing launches completely is greater than the flood tide water level of default breeding-ground, to complete the installation of whole Culture pure seine.
Wherein, the Culture pure seine in above-mentioned steps a can be first assembled, and then whole Transporting is on seashore; Also can be first the parts such as etting sheet, float and the sinker needed for Culture pure seine assembling are first transported on seashore, then complete the last assembling of Culture pure seine by the sea again.
In order to the default stake of the float layer with seabed that ensure Culture pure seine in step b is or/and preset the rope be connected between anchor and can float along with tide bulge and fall, above-mentioned rope is also connected to ball float.
Compared with the mounting technique of existing Culture pure seine, advantage of the present invention is by the natural cause in conjunction with fluctuation tide, large-scale culture pure seine used in shallow sea can be transferred to like a cork the default breeding-ground of Deepwater Open Sea, and Culture pure seine default breeding-ground fixed installation also than being easier to, convenient, there is construction workload little, the advantages such as the cycle is short, originally the Culture pure seine etting packed up in the step c to step e of simultaneously this method adopts gradation to launch, etting launches first by concrete operations exactly after high tide, and the height after etting launches first is greater than the level of ebb tide of default breeding-ground, and be less than its flood tide water level, namely first launch after etting bottom and a spacing close to tidal range can be there is between sea bottom surface, sinker bottom etting is settled down between sea bottom surface, the sufficient time can be had to launch under the effect that the etting of Culture pure seine is conducted oneself with dignity at sinker, after seawater ebb, be settled down to again on sea bottom surface bottom the above-mentioned etting substantially expanded completely, therefore, it is possible to effectively avoid Culture pure seine to occur stacked situation, ensure that the culturing area of Culture pure seine.
