1, a kind of bank protection structure that adopts the earliest is a slight slope, though slight slope can be good at protecting the ecological environment of embankment, the intensity of slight slope is very poor, under the impact than the big flood wave, causes the earth landing easily, when serious even collapse;
2, adopt a kind of by steel concrete or/and the rigidity bank protection that stone masonry is built, this rigidity bank protection is compared with natural embankment or slight slope bank protection, though its intensity and tidiness all are greatly improved, but the ecological environment of embankment is therefore destroyed, such as, toys such as microorganism, frog earth and can't surviving for want of, water plant also can't grow, fish have also lost good that place of laying eggs, and the self-purification capacity of water body also descends greatly;
3, adopt a kind of flexible bank protection structure of gabion structure, the publication number of having applied for as the applicant is the disclosed a kind of dyke gabion baffling structure of patent of invention of CN101029480, though the antidetonation of this flexible bank protection, anti-settlement failure ability are strong, but its shortcoming is that the consumption of not only stone is bigger, and construction volume is also big.
The utility model content:
The technical problem to be solved in the present invention is; provide a kind of and can either play erosion control, anti-skidding and anti-collapse effect embankment; can strengthen the self-purification capacity of water body again; can also reach simultaneously protection embankment ecological environment and afforest and beautify the embankment environmental requirement, and the building method of the less environment protection embankment protection of construction volume.
Technical solution of the present invention is, a kind of building method with environment protection embankment protection of following steps is provided, and it may further comprise the steps:
1., along the embankment trend wave absorption stake is set in the embankment outside;
2., between the wave absorption stake, connect the wave absorption curtain, make between wave absorption curtain and the embankment and form planting bed;
3., in planting bed, insert aquatic plants growth matrix and artificial swamp filler;
4., after aquatic plants growth matrix and artificial swamp filler be received in, in planting bed, plant corresponding water plant.
After adopting above-mentioned steps, compared with prior art, the present invention has the following advantages:
1, under being used of wave absorption stake and wave absorption curtain, the present invention can resist wave, can eliminate the water wave to the washing away of embankment, thereby embankment is played erosion control, anti-skidding and anti-collapse effect;
2, be planting bed between wave absorption stake and wave absorption curtain and the embankment among the present invention, be implanted with corresponding water plant and plant in the planting bed, thereby not only provide good living environment, and strengthened the self-purification capacity of water body for the existence of microorganism and toy and the breeding of fish;
3, the effect of protection embankment ecological environment has not only been played in the growth of growth of water plant and microorganism, toy and fish procreation, and has played the function of afforesting and beautifying the embankment environment;
4, a large amount of stone need be placed in the water on embankment limit differently with prior art, the present invention has used weight lighter wave absorption stake and wave absorption curtain relatively, and therefore, construction volume of the present invention is less greatly.
As a kind of improvement of the present invention, the spacing distance between the described wave absorption stake can be 50cm~200cm; The distance that described wave absorption stake top is lower than ordinary water level can be 0~60cm; The degree of depth that lakebed or river bed are inserted in described wave absorption stake bottom can be 100cm~200cm.It is in order to play good fixation that spacing distance between the wave absorption stake is set to 50cm~200cm; The distance that described wave absorption stake top is lower than ordinary water level is that 0~60cm is in order not influence the view of embankment; In addition, the degree of depth of wave absorption stake bottom being inserted lakebed or river bed is defined as 100cm~200cm and can guarantees fastness after lakebed or river bed are inserted in wave absorption stake bottom.
As another kind of improvement the of the present invention, also can set up fishing net again in the described wave absorption curtain outside, and described fishing net is connected in the wave absorption stake.Because in the water herbivorous fishes is arranged, they may absorb water the seedling of living plant, therefore, the present invention can prevent that these herbivorous fisheses from eating indiscriminately the seedling of water plant after setting up fishing net.
Above-mentioned wave absorption curtain can be geo-grid, bamboo curtain splint or straw screen or mat.
The above-mentioned aquatic plants growth matrix of inserting in planting bed can may further comprise the steps:
A, at first excavate the river bed at embankment place or the bed mud in the lakebed;
B, then these bed muds are poured in the planting bed;
Above-mentioned artificial swamp filler refers to slag or/and cobble.
