1. An ecological revetment to regulate wandering rivers, wherein the revetment is composed of porous concrete-piles, ecological connecting-plates, an ecological viewing corridor and a sloping green-belt; the bottoms of the porous concrete-piles are fixed in the soil of a river bank slope; the middle parts and lower parts of the pile are located below a water surface, while the upper parts are located above the water surface; the ecological connecting-plates are fixed in the middle parts of the porous concrete-piles; the ecological connecting-plates are located between two adjacent porous concrete-piles, and the plates are also submerged below the water surface; the ecological viewing corridor is fixed on the top of the porous concrete-piles; the sloping green-belt is arranged in parallel with the ecological viewing corridor, and the sloping green-belt is located on the river bank slope;
each porous concrete-pile is a precast pile with a T-shaped section; two upper wings of the porous concrete-pile comprise a convex wing on one side and a concave wing on another side; the concave and convex wings of two adjacent porous concrete-piles are merged together; inserting ears are provided on the top of the porous concrete-pile, and longitudinal and transverse hanging ears are furnished on sides of the middle part of the porous concrete-pile;
each ecological connecting-plate has a prefabricated plate-like structure, and the plate is mainly composed of a front inserting-plate, several middle transverse inserting-plates and a rear inserting-plate; both sides of the front inserting-plate and rear inserting-plate are connected with the longitudinal hanging-ears of the porous concrete-piles; both ends of the middle transverse inserting-plates are inserted into the transverse hanging ears of the porous concrete-piles; a plurality of middle transverse inserting-plates, which are located between the front inserting-plate and rear inserting-plate, are parallelly arranged from the top to bottom of the revetment; the inserting-plates are fixed with pouring cement; the longitudinal section of the front inserting-plate is curved, and so is the rear inserting-plate; a plurality of ecological holes with different sizes exist in the front inserting-plate, rear inserting-plate, and middle transverse inserting-plates; a transverse anchor-rod is arranged on the rear inserting-plate; the whole structure is fixed on the bank slope with an anchor rod;
the ecological viewing corridor is mainly composed of a bottom plate, an ecological guardrail and green plants; the bottom plate has a plate-like structure; a plurality of inner grooves exist on the lower surface of the bottom plate; the inserting ears on the tops of the porous concrete-piles are inserted into the inner grooves; some grooves are reserved on the upper surface of the bottom plate facing the river;
the ecological guardrail comprises connecting pieces, outer board-grooves and railings; a plurality of outer board-grooves are arranged in a row and placed in the groove; adjacent outer board-grooves are connected with the connecting pieces; two railings are located at the outermost end of the ecological guardrail, and the bottoms are fixed on the bottom plate; the railings and outer board-grooves are connected with the connecting pieces to form a guardrail; water-storage tanks, planting tanks and automatic spray-pipes are arranged in the outer board-grooves; the water-storage tanks are placed at the bottoms of the outer board-tanks, while the planting tanks are placed above the water-storage tanks; the upper parts of the water-storage tanks are provided with overflow holes, and excess water can flow into gaps between shells of the outer board tanks and water-storage tanks; the bottoms of the planting tanks are permeable plates; an anti-filter geotextile is laid on the permeable plates; the permeable plates are provided with a plurality of water-leakage holes, so that the excess water in the planting tanks flows into the water-storage tanks; the automatic spray-pipes are inserted into the water-storage tanks to provide water sources for the planting tanks;
the sloping green-belt, a combination of various plants, is located at the side of the ecological viewing corridor away from the river.
