Abstract
A construction method of a river beach pool ecological purification system relates to a river ecological restoration technology. The technical scheme of the invention adopts a section of curved river channel as a construction area, wherein the construction area is provided with a section of river channel with the central angle of 90-160 degrees of the river channel and more than 2 curved parts, and the linear length of the construction area is 5-7 times of the average width of a main river channel of the river channel, and the construction area is characterized in that 50cm-2m deep ponds are constructed at the bent tops of the upper and lower ends of the river channel in the construction area; excavating earthwork of a deep pool to construct a shoal at the center of a straight river channel between two bends of the river channel in a construction area and at the side of a convex bank at a bend, wherein the shoal is 10-50 cm higher than the original river bottom to form a river center beach or a river side beach, and stacking large stones with the specification of 30-80 cm on the water facing side of the constructed shoal; and constructing a fish channel with the concave depth of 20-50cm in the center of the constructed downstream river channel of the riverside beach. The invention is used for pollution control and ecological restoration of rivers.
Description
Technical field
The present invention relates to a kind of River ecological restoration: techniques field.
Background technology
River ecological restoration: techniques is one of important measures carrying out Discussion On Measures of Rivers Pollution Treatment in the last few years, what commonly use in current practice is oxygenation aeration etc. in ecological riverway, eco-embankment, artificial swamp and river course, these measures are also universally accepted and approve, all by artificially auxiliary transformation and design, form rational structure, realize ecosystem self-regeneration function.
The general principle of at present conventional river ecosystem restoration measure is all that the structure of the formation derived under river nature inspires, in fact feature and the structure of a lot of natural river is also had, be worth carrying out imitating in river ecosystem restoration and design, the shoal of self-assembling formation and pool in such as river, its current are association of activity and inertia, speed combines, and in water body flow diversity and bio-diversity, increase oxygen in water, mud silt, strengthens the aspects such as habitat function and all has advantage.So far, in river, realized pool, the beach ecological purification system in river by artificial measures, there is no report and the precedent applied in China.
Summary of the invention
The object of the present invention is to provide a kind of method being realized pool, the beach ecological purification system in river in river by artificial measures.
Technical scheme of the present invention adopts one section of bending river course as structure region, there is one section to be momentum model central angle to be the section of 90 ° ~ 160 ° in this structure region, and there are more than 2 crooked positions, the lineal measure building region is 5-7 times of this section main stem mean breadth, it is characterized in that the curved top at the upper and lower side turning, river course in selected structure region, namely dig 50cm-2m under closing on concave bank side, build pool; The earthwork of excavation pool is used for river course two in selected structure region curved between the river course central authorities of straight section and turning face structure shoal, convex bank side, shoal exceeds former river bed 10cm-50cm, form river island or beach, river bank, for preventing current scour, stacking specification in the upstream face side building shoal is 30 ~ 80cm ratchel; Build fish passage in the river island downstream river course central authorities built, the recessed degree of depth of fish passage is 20-50cm.
This method has simple and convenient, easy to operate, the easy penetration and promotion of structure engineering, in engineering, cut and fill balance utilizes, without spoir, the outstanding feature of manual maintenance is not needed after system stability, recover river natural, ecological structure, there is remarkable result to the depollution of environment, sedimentation, enhancing habitat function, ecology and bio-diversity, be with a wide range of applications in the pollution control and restoration of the ecosystem in river.
Accompanying drawing explanation
Fig. 1 is pool, beach, a kind of river of the present invention ecological purification system layout schematic diagram.
Detailed description of the invention
The present invention's (see accompanying drawing 1) utilizes one section of bending river course as structure region, there is one section to be momentum model central angle to be the section of 90 ° ~ 160 ° in this structure region, and there are more than 2 crooked positions, the lineal measure 1 building region is 5-7 times of this section main stem mean breadth, the curved top at the upper and lower side turning, river course in selected structure region, namely dig 50cm-2m under closing on concave bank side, build pool 2; The earthwork of excavation pool is used for river course two in selected structure region curved between the river course central authorities of straight section and turning face structure shoal, convex bank side, shoal exceeds former river bed 10cm-50cm, form river island 3 or beach, river bank 4, for preventing current scour, stacking specification according to river direction 7 in the upstream face side building shoal is 30 ~ 80cm ratchel 5; Finally build nick part as fish passage 6 in the river island downstream river course central authorities built, the recessed degree of depth of fish passage is 20-50cm.
