Detailed Description

The utility model will be further described with reference to the drawings and examples.

In order to reduce impact damage of seawater to the ecological seawall, the survival rate of saline-alkali resistant plants in the ecological seawall planting pool 200 is improved, wave-eliminating belts formed by a large number of soil-protecting blocks are arranged on one side of the planting pool 200 close to the seawater, and the soil-protecting blocks are arranged along the edge of the planting pool 200, so that when sea waves occur, the sea waves firstly impact the soil-protecting blocks at the edge of the planting pool 200, the sea waves are prevented from directly impacting the planting pool 200, and soil loss in the planting pool 200 is reduced.

As shown in fig. 1 to 3, a soil-retaining block includes a main block body 100, and the main block body 100 is a substantially rectangular parallelepiped member having the same length and width but a height smaller than the length and width. In order to improve the wave preventing and eliminating effects of the main block 100, a main through hole 120 extending in the vertical direction is formed in the middle of the main block 100, when the main block 100 is flushed by the sea waves, part of the sea waves can enter the main through hole 120, and the sea waves entering the main through hole 120 collide with each other to form vortex, so that the kinetic energy of the part of the sea waves is quickly reduced, and the aim of reducing the integral kinetic energy of the sea waves is fulfilled. To further increase the wave dissipating effect of the main block 100, one or more secondary through holes 130 are also provided in the main block 100, which secondary through holes 130 are arranged around the main through hole 120. The wave-dissipating effect of the main block 100 is improved by providing a plurality of auxiliary through holes penetrating up and down in the main block 100.

In order to improve the wave-dissipating effect of the main block 100, four lower supporting feet 140 are disposed on the bottom surface of the main block 100, and the four lower supporting feet 140 are disposed at four top corner positions of the main block 100, so that a support can be formed for the main block 100 to enable the main block 100 to be stably placed on the ground, a gap is formed between the bottom surface of the main block 100 and the ground, sea waves entering the gap collide with the bottom surface of the block and the ground due to space limitation, and front waves and rear waves collide with each other, so that the kinetic energy of the sea waves is rapidly reduced. On the other hand, the sea waves entering the main through hole 120 and the three auxiliary through holes 130 can rapidly flow away through the gaps below the main block 100, so that the problem that the water accumulation of the main through hole 120 and the auxiliary through holes 130 affects the wave eliminating effect of the main block 100 is avoided. Meanwhile, the space below the main block 100 also increases the inhabitation space for fishes and shellfishes, increases the living space for plants, and is beneficial to improving the ecological environment.

Further, two lower legs 140 of the main block 100 on the side facing the planting pool 200 are connected together to form a diaphragm 160, the bottom surface of the diaphragm 160 is flush with the bottom surfaces of the other two lower legs 140, and the width of the diaphragm 160 is not smaller than the width of the main block 100. Like this, the wave that enters into main block 100 below space receives the separation of diaphragm 160 and can't directly form the impact to planting pond 200, guaranteed that the soil body in planting pond 200 at main block 100 rear is stable, can reduce the water and soil loss problem that the wave impacted and bring, can also reduce the green planting in sea water direct contact planting pond 200 that contains a large amount of salt, help improving the survival rate of planting in the pond 200, make the plant in the planting pond 200 can long-term growth, maintain the long-term ecology of seawall.

The top surface of the main block 100 is also provided with an upper supporting leg 150 symmetrical to the lower supporting leg 140, and the arrangement of the upper supporting leg 150 can increase the fluctuation of the top surface of the main block 100, so that the top surface of the main block 100 has a better wave-dissipating effect.

Because the plurality of soil-retaining blocks are arranged along the coastline of the sea of the planting pool 200 when in use, the plurality of soil-retaining blocks form the wave-dissipating belt to jointly play the role of wave-dissipating and soil-retaining, the overall wave-dissipating effect of the wave-dissipating belt can be improved by adding wave-dissipating structures between two adjacent soil-retaining blocks and the soil-retaining blocks.

Specifically, the main block 100 is provided with grooves 110 on four sides, and the grooves 110 have a trapezoidal cross section. The groove 110 at the front end of the main block 100 can further reduce the uniformity of the head-on surface of the main block 100, and can better eliminate the energy of the direct impact of sea waves. The grooves 110 on both sides of the main block 100 combine the grooves 110 of two adjacent soil-protecting blocks attached together to form water through holes, which not only reduce the energy of sea waves, but also increase the beauty of the wave-preventing belt formed by the soil-protecting blocks to a certain extent.

An alternative embodiment of the present utility model is shown in fig. 1-3. In this embodiment, the main through hole 120 is square, 3 auxiliary through holes 130,3 are disposed around the main through hole 120, and the auxiliary through holes 130 on the front side and the left and right sides of the main through hole 120 are respectively disposed, so that the auxiliary through holes 130 on the front side and the main through hole 120 cooperate to further improve the attenuation effect on the sea waves, and the auxiliary through holes 130 on the left and right sides of the main through hole 120 and the main through hole 120 together enable most of the sea waves which are flushed on the top surface of the main block 100 to enter the holes, so that the sea water which is flushed into the planting pool 200 is reduced. On the other hand, the main block 100 and the sub through holes 130 provide vertical space for the growth of aquatic plants or saline-alkali tolerant plants in the gaps below the main block 100, so that the saline-alkali tolerant green plants below the main block 100 can grow upwards, and the ecology of the soil-retaining block is improved. Plants growing in the through holes are protected by the through holes, so that the impact of sea waves on green stems and leaves can be avoided, and the survival rate of plants below the main block 100 is improved.

In order to ensure that the main through hole 120 and the auxiliary through hole 130 can meet the wave dissipating requirement, the side length of the main through hole 120 is 0.2L-0.25L, and the diameter of the auxiliary through hole 130 is 0.15L-0.2L, wherein L is the side length of the square top surface of the main block 100.

In this embodiment, the lower leg 140 has a substantially inverted quadrangular frustum shape, that is, the cross section of the lower leg 140 gradually increases from bottom to top. The two sides of the inner side of the lower supporting leg 140 are inclined planes, so that the strength of the lower supporting leg 140 can be improved, and the inclined planes can also play a certain auxiliary role in reducing the sea wave kinetic energy.

In order to improve the construction efficiency of the soil-protecting block, the soil-protecting block is a member prefabricated from green concrete.

The wave eliminating belt can effectively eliminate the sea waves rushing up along the slope surface, reduce the kinetic energy and impact force of the sea waves, greatly reduce the influence of the sea waves on the planting pool 200 and plants in the pool, and improve the survival rate of the plants.

It should be noted that, in order to ensure the wave-dissipating effect of the soil-protecting block, when the wave-dissipating belt is constructed, the rear end face of the soil-protecting block faces the planting pool 200, that is, the transverse partition 160 of the soil-protecting block abuts against the edge of the planting pool 200, so as to avoid the impact of sea waves on the soil at the lower part of the planting pool 200 and keep the soil of the planting pool 200 stable.

A second nonwoven geotextile layer 900 is also provided between the wave dissipating strip and the planting pool 200 to reduce leakage of seawater to the planting pool 200 and reduce the effect of seawater to plants.
