Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1 and fig. 2, do the utility model discloses an ecological bank protection of hydraulic engineering mainly comprises spud pile 11, anti-loss otter board 12, fixed frame and planting base plate etc..

The fixing pile 11 is directly pressed into the soil by using a wooden pile or a bamboo pile. The fixed frame consists of four mutually vertical and fixed planting grooves 13, and holes 14 are uniformly distributed on the bottom surfaces of the planting grooves 13 and can be permeable to water and air. The planting tank 13 is made of fiber reinforced plastic, namely commonly known as glass fiber reinforced plastic, which is low in density, corrosion-resistant, not easy to decompose, generally has a service life of about fifty years and can support the growth of trees to the mature period.

The anti-loss mesh plate 12 is pressed into the soil along with the fixing pile 11, when the pressing is difficult, a trench can be dug on the ground, the anti-loss mesh plate 12 is buried in the soil after being placed in the trench, and the upper end of the anti-loss mesh plate is tied to the planting groove 13 by iron wires. The anti-loss mesh plate 12 can also be formed by weaving wood strips or bamboo strips, and is continuously decomposed with the increase of the using process, finally changed into nutrients and absorbed by vegetation.

Each planting groove 13 is connected with a lantern ring 15, each lantern ring 15 is provided with a tightening screw 3, the lantern ring 15 is sleeved on the adjacent fixing pile 11 and then the tightening screw 3 is screwed down, and then the planting grooves 13 can be fixed on the fixing pile 11. The fixing frames are installed in a stacking mode, two lantern rings 15 are sleeved on each fixing pile 11, namely, each row of fixing frames are located in one plane, adjacent rows are located in different planes, and the height difference is leveled by soil.

Referring to fig. 1 and 3, the planting base plate is composed of a base plate 21 and hooks 23 mounted on the side edges of the base plate 21, through holes 22 are uniformly distributed on the bottom surface of the base plate 21, 2-3 hooks 23 are arranged on each side surface, and the hooks 23 are hung on the adjacent planting grooves 13. When the planting substrate can also use the wire netting, the wire netting is low in price and high in strength, and the using requirement for early soil fixation can be met.

The implementation principle of the embodiment is as follows:

during installation, the fixing piles 11 and the anti-loss mesh plates 12 are sequentially pressed into soil, then the fixing frames are sequentially placed at each position, during placement, the lantern rings 15 on each planting groove 13 in the fixing frames are sleeved on the adjacent fixing piles 11, then the jacking screws 3 on each lantern ring 15 are screwed down, and the planting grooves 13 are tied to the anti-loss mesh plates 12 through iron wires. Finally, the planting substrate is placed in each fixed frame, and the hooks 23 are hung on the adjacent planting grooves 13.

In the greening process, floating soil is firstly put on the planting base plate and the planting groove 13, grass seeds are scattered, the death rate of the grass seeds is high in the early greening process, particularly the grass seeds on the planting base plate need to be replanted, and shrubs begin to be planted when no piece of soil is exposed in the whole installation area.

When shrubs are planted, the shrubs are directly planted on the planting substrate, and in the growing process, the root systems of the shrubs can penetrate through the planting substrate and extend into soil below the planting substrate. In consideration of factors such as precipitation, density and soil bearing capacity, shrubs need to be planted in batches, and planting positions of trees are reserved.

When the shrub reaches a certain amount, trees begin to be planted in the reserved position, and at the moment, the planting substrate in the reserved position begins to be rusted and needs to be removed together. During the growth process of the trees, the root systems of the trees are gradually developed, the planting grooves 13 are also detached, and the vacant positions can be used for supplementing shrubs or grass seeds. The appearance and growth of trees mean the initial formation of ecology, and at the moment, the fixing piles 11 and the anti-loss net plates 12 start to gradually decay, and the decayed fixing piles and the anti-loss net plates can become humus to provide nutrients for shrubs, arbors and the like.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
