Abstract
The present invention relates to water conservancy engineering, especially the tackling of seasonal riberbed and river course. The present invention is characterized by that subsiding stepped water accumulating river with subsiding dams is constructed without changing the cross section area and flood discharging runoff and the water accumulating riverbed is lowered gradually from the upstream to the downstream. The stepped water accumulating riverbed makes it possible to utilize water comprehensively for beautifying environment, preventing riverbed desertification, regulating air humidity, maintaining ecological balance and safety discharge flood.
Description
(1) technical field
The present invention relates to water conservancy and administer the engineering field, relate in particular to the regulate and store improvement engineering field in riverbed and river course of seasonality.
(2) background technology
Seasonality cutout or the less dry river basin of flow that riverbed and river course normally form because of the regional condition influence of regulating and storing, its natural grade is big, because of the The Long-term Effect of season, weather, the upper water inadequate resource mainly is because exposed grit, cobble, desertification riverbed are aggregative.Regulate and store riverbed and river course of the city section of passing by particularly, seasonality is more representative, and river cutout season, not only water is withered, do in the river, and it is serious to desertify, and makes refuse rubbish pour the river course into.In the existing operation technique, the regulate and store improvement in riverbed and river course only only limits to smooth riverbed, mediation riverbed, cleaning refuse, reinforces river levee to seasonality, and is both simple, backward again; The comprehensive utilization weak effect, influence ecological environment and city are attractive in appearance.Application number is the patent application of 99112802.8 disclosed " building the new methods of river channel type reservoir ", is digging pit, pouring into or building reservoir under the river bed below the riverbed in river course, do not relating to riverbed and river regulation method.
(3) summary of the invention
The purpose of this invention is to provide a kind of seasonality that solves and regulate and store that riverbed and river course are withered because of the water that cutout or water shortage cause, do in the river, the riverbed desertifies, exposed problem; preserve the ecological environment; guarantee safe flood discharge, the sunk type notch cuttype of realizing the comprehensive regulation and development and use regulate and store riverbed and river regulation method.
Realize that technical scheme of the present invention is: utilize the river channel natural gradient and drop,, under the prerequisite that does not change former sectional area in river course and flood discharge run-off, on riverbed and river course, build the retaining river of sunk type notch cuttype according to river course different length and width; The riverbed that is in each grade retaining river in downstream is lower than the riverbed, retaining river of its upstream, builds dam, sunk type ladder river on the cross section of the river course flow direction; Build sunk type ladder river levee in the original bed position in river course, first section both sides are built the hurdle and are cut Shi Shaqu, flow into the waters after making water sedimentation, form territory, well-bedded retaining river reach.Carry out comprehensive development and utilization in each retaining korneforos,, can also build ecoscape districts such as sculpture waterborne, music fountain, waterwheel waterfall as culturing, afforest, swim, skate or the not busy public place of entertainment of other body.
The present invention has following beneficial effect:
1, for beautifying river course environment, particularly the pass by environment in river course of beautifying city has important function, can prevent from effectively that the river course from desertifying to pollute, and regulates air humidity, keeps ecological balance;
2, because of being to utilize the river channel natural gradient and drop, building becomes the retaining of sunk type notch cuttype river; Cutting depth is shallow, engineering quantity is little; But build the materials in-site collecting, cost is low, technology is simple, easy to implement;
3, former part riverbed realization greening both can be reinforced the riverbed, can beautify the environment again; Can realize the improvement of part section or full section;
4, realize the river course comprehensive regulation and effectively utilize, guarantee flood discharge safety; Also can utilize the waterwheel irrigation by pumping, also can utilize other water intake facilities that water is used, the mankind are had everything to gain and nothing to lose.

(5) specific embodiment
As Fig. 2, shown in Figure 3: sunk type notch cuttype regulate and store riverbed and river course, utilize the river channel natural gradient, under the prerequisite that does not change former sectional area in river course and flood discharge run-off, on the river course, build the retaining river territory 2 of sunk type notch cuttype; Each grade sunk type ladder riverbed 6 that is in the downstream is lower than the riverbed, retaining river of its upstream; On the cross section of building the sunk type notch cuttype on the river course, build dam, sunk type ladder river 5; Between dam, two sunk type ladder rivers 5, form sunk type ladder riverbed 6, build sunk type ladder river levee 3 in original bed 4 positions in river course; Form territory, well-bedded retaining river reach; It is natural pebble layer 7 that the riverbed reaches underground down.Referring to Fig. 1, carry out comprehensive development and utilization in each retaining river territory 2, region planting greenings such as original bed 4 between former river levee 1 and sunk type step river levee 3, form green area 8 and roadside greening district 9, waterwheel 10 is irrigated by lifting water to a higher level with a water pump, etc. in 2 installations in retaining river territory, utilization is irrigated by lifting water to a higher level with a water pump, etc. 10 pairs of trees of waterwheel and is irrigated, and can also combine and utilize water with other intake equipment.Referring to Fig. 4, the long-pending husky zone 11 of hurdle stone is built in the both sides in first section retaining river course in the upstream, build the hurdle and cut dam, river 12 on the river course, the gradient in long-pending husky regional 11 middle parts of hurdle stone and left side is 5/1000ths to 8/1000ths, and the gradient on long-pending husky regional 11 right sides of hurdle stone is 3/1000ths to 5/1000ths.
Water is wandered to the long-pending husky zone 11 of hurdle stone from original bed 4, in the control of sandstone separating process, because the proportion difference of sandstone and hurdle cut the effect of the dam, river 12 and the gradient, make heavy cobble draw the left side of gathering along the gradient in the long-pending husky zone 11 of hurdle stone, the grains of sand that proportion is little draw the right side of gathering in the long-pending husky zone 11 of hurdle stone along the gradient, water cuts dam, river 12 by the hurdle and tumbles first retaining river territory 2 of inflow, flow to the most last retaining river territory 2 downwards always.After the flood, stone long-pending husky zone 11 in hurdle promptly becomes the husky stock ground of natural stone.
