Its technical solution includes:
A kind of Zhou Jinzhou goes out sedimentation basin Inlet and outlet water conductance with modular unit, and a generally body structure, it is heavy to be mounted on
On the pool wall in shallow lake pond, it is characterised in that: it is by several groups that the Zhou Jinzhou, which goes out sedimentation basin Inlet and outlet water conductance with modular unit,
Modular unit is spliced, wherein every group of modular unit includes irrigation channel, water outlet channel, water distributing mechanism and water conservancy diversion skirt
Plate, the irrigation channel and water outlet channel are co-walled, are separated by partition therebetween；
The irrigation channel uses the unidirectional water distribution form of tapered truncation surface, is provided in the bottom of the irrigation channel
Several distributing holes are arranged for Unequal distance between adjacent distributing hole, and the water distributing mechanism is arranged in below the distributing hole,
The lower section of the partition is arranged in the water conservancy diversion skirtboard；
The water outlet channel unilateral side is provided with effluent weir hole, the cabinet is also equipped with lid.
As a preferred solution of the present invention, the material of every group of modular unit is carbon steel anti-corrosion material, stainless steel, gathers
Propylene or polythene material.
As another preferred embodiment of the invention, above-mentioned distributing hole is that round or rectangle, above-mentioned water distributing mechanism are
Tee tube, the pipe both ends in the horizontal direction of above-mentioned tee tube are parallel to the pool wall of sedimentation basin, and water outlet shape is wedge
Shape.
Further, peep hole is provided on above-mentioned lid.
Further, above-mentioned effluent weir hole shape is round, oval, triangle, trapezoidal or rectangle.
Further, the spacing between adjacent distributing hole successively becomes smaller since the water inlet end of inlet channel.
Advantageous effects brought by the present invention are as follows:
(1) modular unit is matched using integrated Inlet and outlet water conductance, very good solution goes out to precipitate due to traditional Zhou Jinzhou
Pond water distribution system and outlet system main part reinforced concrete structure, inlet channel use the unidirectional water distribution form of tapered truncation surface
Lead to the problem of non-uniform that the difficulty of construction of width curve is high, precision is not easy guarantee, water inlet water distribution and effluent collection.
(2) in the case where proposing the mark amount of proposing demand, be very suitable to center water inlet peripheral effluent sedimentation basin transform as periphery into
There is modularization to inlay, speed be transformed fastly, the advantages such as install convenient, project amount are small for the mode of water peripheral effluent.
(3) it is suitble to newly-built Zhou Jinzhou to go out sedimentation basin, Inlet and outlet water conductance match system modular unit has plasticity strong, peace
Fill that flexible operation is convenient, and structure is accurate, error is small, ensures uniformity into water water distribution and effluent collection.
(4) sedimentation basin Inlet and outlet water conductance match system modular unit has good economy, environmental and social benefits.
