Abstract
The utility model discloses an ecological friendly type spur dike of city river, include the bottom surface, be located upstream face and back side above the bottom surface, the upstream face is a quadrant face, and the back side of being connected with the upstream face contains 3 grade at least steps, and the height of every step and the ratio of width are 0.6-0.7, and the height of upstream face and back side is the same with the spur dike height. The utility model discloses an ecological friendly type spur dike of city river, the design of the disc of its upstream face helps reducing to come the velocity of flow of water, reduces rivers and to the erodeing of spur dike, reduces the formation of dam body upper reaches silt, the plant can be planted simultaneously to flow dissipation to the notch cuttype design of its back side on the step, water purification more can richen water view level better, and the construction is simple, and has compromise the ecological of city river and view benefit, improves city ecological environment to a certain extent.
Description
Technical field
The utility model relates to a kind of urban river ecological friendly groynes, belongs to Design of Water Resources and Hydroelectric Projects and technical field of construction.
Background technology
Along with the raising of socio-economic development and living standards of the people, under the background that urbanization process is constantly accelerated, the importance of Urban Water Environment is further outstanding.City river is the main carriers in urban water conservancy project, and be also the main composition element in Urban Water Environment and Ecology, the quality of its ecological environment directly affects the Ecological Civilization Construction in whole city.Traditional river controlling projects is main towards controlling flood and draining flooded fields, and considers less to Urban Water Ecological Environment aspect.
Groynes is a comparatively common class hydraulic engineering, generally refers to that or oblique orthogonal with riverbank stretches into the river regulating structure in river course, is usually used in protecting riverbank from the direct erosion of incoming flow, improving navigation channel, safeguards and plays an important role in river course form etc.City river, owing to closing on dense population areas, has usually been accepted more city stain disease, has been caused the waterfront landscape Quality Down of urban river, have a strong impact on the physical and mental health of townsfolk.Therefore, build green groynes, under the basic conditions such as satisfied flood control, navigation, take into account river water quality, ecology and view aspect, will there is very large social and ecological benefit.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of urban river ecological friendly groynes, the basal needs such as flood control, navigation can either be met, also can improve the eco-friendly type groynes of city river water quality water environment, give full play to the usefulness of green water management engineering.
Technical scheme: for solving the problems of the technologies described above, a kind of urban river ecological friendly groynes of the present utility model, comprise bottom surface, be positioned at upstream face above bottom surface and back side, described upstream face is a quadrant face, the back side be connected with upstream face comprises at least 3 grades of steps, the height of each step and the ratio of width are 0.6 ~ 0.7, and upstream face is identical with groynes height with the height of back side.
As preferably, wherein, H is the height of groynes to the progression N=H/h of described step, and h is the height of step, and every grade of shoulder height is no more than 50 centimetres.
As preferably, described step is provided with groove, is placed with the compost cultivating planting plants in groove.
As preferably, described plant comprises amphibious plant, emergent aquactic plant and submerged plant, and wherein amphibious planting is in upper strata step, and submerged plant planting is in bottom step, and emergent aquactic plant is planted in other steps.
As preferably, the width B of described bottom surface is drawn by following formulae discovery: B=H+N*b, and wherein, H is the height of groynes, and N is the progression of step, and b is the width of step.
Beneficial effect: urban river ecological friendly groynes of the present utility model, the disc of its upstream face is designed with the flow velocity helping reduce water, reduces current washing away groynes, reduces the formation of dam body upstream mud; The notch cuttype design of its back side, can to current energy dissipating, planting plants on step simultaneously, can not only purify water better, more can enrich water landscape level, the construction of the utility model dam body build is simple, and has taken into account ecology and the Landscape benefit of city river, improves urban ecological environment to a certain extent.
Accompanying drawing explanation
Fig. 1 is the longitudinal plan according to a kind of urban river ecological friendly groynes of the present utility model;
Fig. 2 is the top view according to a kind of urban river ecological friendly groynes of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As depicted in figs. 1 and 2, according to certain city river topographic(al) data, two sides, river course landform, peak flood flow, design flood level etc., with reference to Code for design of levee projects, selected dam body builds position, determine that river width L be 21m and groynes 1 is highly 1.8m, upstream face 2 for radius be the quadrant face of 1.8m.
As shown in Figure 1, build the progression of the step 5 of back side 3: when N is 4, step 5 height h is 45cm, and be less than 50cm, calculate simultaneously to the width b of step 5, make the depth-width ratio of step 5 between 0.6 ~ 0.7, COMPREHENSIVE CALCULATING desirable step 5 width b is 75cm.Build the width of bottom surface 4: B=H+N*b, then the width of bottom surface 4 is 4.8m.Build the length of groynes 1: generally get about 1/3 of river width, river width is 21 meters, and groynes length is about 7m.
At the built-in compost planting plants of back side 3 step, amphibious plant yellow flag, swallow flower etc. in the 4th layer of step kind, submerged plant hornwort, black algae etc. in first floor step kind, in the second and the 3rd emergent aquactic plant cattail, reed etc. in step kind.
This city river friendly groynes interlaced arrangement in both sides, river course, as shown in Figure 2, the adjacent groynes distance L of homonymy
0=2L, then the adjacent groynes of homonymy is at a distance of 42m.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
