Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower engineering technology, specifically relating to an ecological slope protection structure for water conservancy and hydropower engineering construction. Background Technology

[0002] Ecological slope protection is a method of reinforcing and beautifying slopes using plants and ecological engineering techniques. Common ecological slope protection methods typically involve laying hexagonal bricks on the slope and planting plants in the planting holes of the bricks. This helps prevent soil erosion, improve the environment, and enhance aesthetics.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN223343295U discloses a hexagonal block ecological slope protection structure. After it is laid, planting soil and seeds need to be filled into the interior of the hexagonal blocks. The newly laid planting soil structure is loose and the seeds are exposed. Once it rains, raindrop splash and surface runoff will immediately cause serious soil erosion and seed washing away, leading to project failure.

[0004] Therefore, it is necessary to design an ecological slope protection structure for water conservancy and hydropower engineering projects that can buffer the impact of raindrops, protect the planting soil and seeds from erosion during the germination period, and ensure the construction effect, in order to solve the current technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an ecological slope protection structure for water conservancy and hydropower engineering structures that can buffer the impact of raindrops, prevent the planting soil and seeds from being washed away during the germination period, and ensure the construction effect.

[0006] The technical solution of this utility model is as follows: an ecological slope protection structure for water conservancy and hydropower engineering construction, comprising slope protection bricks evenly laid on the slope surface, adjacent slope protection bricks being fixedly connected by connectors, and an ecological soil stabilizing layer being provided inside the slope protection bricks; the ecological soil stabilizing layer having a degradable water-absorbing layer, a planting soil layer, and a degradable buffer layer arranged from bottom to top inside the slope protection bricks; the planting soil layer being planting soil mixed with base fertilizer and seeds; the degradable buffer layer being a biodegradable plastic mesh or plant fiber mesh; and the degradable water-absorbing layer being a degradable non-woven fabric.

[0007] Furthermore, the slope protection bricks are provided with connecting grooves at all four edges; the connector has a connecting block that matches the groove formed by splicing two adjacent connecting grooves, and the connecting block is bonded and fixed to the connecting groove.

[0008] Furthermore, at least one connecting hole is provided inside the connecting groove, and a connecting rod matching the connecting hole is provided on the connecting block. The connecting rod and the connecting block are an integral structure; the connecting rod is bonded and fixed inside the connecting hole.

[0009] Furthermore, the length of the connecting rod is 0.5 to 1.5 cm longer than the length of the connecting hole, and the end of the connecting rod is provided with a tapered head.

[0010] Furthermore, the bottom of the slope protection bricks is uniformly provided with permeable grooves, and the perimeter of the degradable water-absorbing layer is fixedly disposed on the inner side of the slope protection bricks above the permeable grooves; the perimeter of the degradable buffer layer is fixedly disposed on the inner side of the slope protection bricks.

[0011] Furthermore, the distance between the degradation buffer layer and the top of the slope protection brick is 0.5 to 1.0 cm.

[0012] Furthermore, the planting soil layer is a mixture of base fertilizer, seeds, and water-retaining agent.

[0013] The beneficial effects of this utility model are:

[0014] (1) In this utility model, the slope protection brick has an integrated ecological soil stabilization layer inside. The ecological soil stabilization layer has a degradable buffer layer that supports the planting soil layer inside the slope protection brick. The planting soil layer contains not only planting soil, but also base fertilizer and seeds. After laying, there is no need to fill the planting soil and sow seeds inside, thus shortening the on-site construction cycle.

[0015] (2) The degradation buffer layer can not only reduce the leakage of the planting soil layer, but also provide initial strength and erosion resistance, so that the planting soil and seeds are protected from erosion during the germination period, ensuring the construction effect;

[0016] (3) After the rainwater infiltrates, the seeds inside the planting soil begin to germinate. Under the action of sunlight, rainwater and soil microorganisms, the degradation buffer layer will gradually disintegrate and degrade. At this time, the plant roots have penetrated into the soil, forming a reinforced root network, which replaces the soil-fixing function of artificial materials.

[0017] (4) The biodegradable absorbent layer is a biodegradable non-woven fabric, which can not only prevent soil loss in the planting soil layer, but also transport water from the lower layer upward through capillary action, maintain the moisture at the bottom of the upper planting soil layer, and provide a soft, moist and breathable interface for the young roots that grow downward in the early stage, encouraging the roots to penetrate into the native soil instead of growing horizontally.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, an ecological slope protection structure for water conservancy and hydropower engineering is disclosed, including slope protection bricks 1 evenly laid on the slope surface. Adjacent slope protection bricks 1 are fixedly connected by connectors 2. An ecological soil stabilizing layer 3 is provided inside the slope protection bricks 1. The ecological soil stabilizing layer 3 has a degradable water-absorbing layer 33, a planting soil layer 32, and a degradable buffer layer 31 arranged from bottom to top inside the slope protection bricks 1. The planting soil layer 32 is planting soil mixed with base fertilizer and seeds. The degradable buffer layer 31 is a biodegradable plastic mesh or plant fiber mesh. The degradable water-absorbing layer 33 is a biodegradable non-woven fabric. In this embodiment, the ecological soil stabilizing layer 3 is integrated inside the slope protection bricks 1. The ecological soil stabilizing layer 3 has a planting soil layer 32 supported inside the slope protection bricks 1 by the degradable buffer layer 31. The planting soil layer 32 not only contains planting soil, but also contains base fertilizer and seeds. After laying, it is not necessary to fill it with planting soil and seeds. Sowing shortens the on-site construction cycle; the degradable buffer layer 31 not only reduces leakage of the planting soil layer 32, but also provides initial strength and erosion resistance, protecting the planting soil and seeds from erosion during the germination period and ensuring construction effectiveness; after rainwater infiltration, the seeds inside the planting soil layer 32 begin to germinate. Under the action of sunlight, rainwater and soil microorganisms, the degradable buffer layer 31 will gradually disintegrate and degrade. At this time, the plant roots have penetrated deep into the soil, forming a reinforced root network, replacing the soil-fixing function of artificial materials; the degradable absorbent layer 33 is a biodegradable non-woven fabric, which not only prevents soil loss from the planting soil layer 32, but also transports water from the lower layer upward through capillary action, maintaining the moisture at the bottom of the upper planting soil layer 32. At the same time, it provides a soft, moist and breathable interface for the young roots that are initially growing downward, encouraging the roots to penetrate downward into the native soil instead of growing horizontally.

[0025] In some embodiments, the slope protection brick 1 has connecting grooves 11 at all four edges; the connector 2 has a connecting block 21 that matches the groove formed by splicing two adjacent connecting grooves 11, and the connecting block 21 is bonded and fixed to the connecting groove 11; specifically, the connecting block 21 is bonded and fixed to the connecting groove 11 by epoxy resin adhesive. In order to shorten the construction cycle, a fast-drying epoxy resin adhesive can be used.

[0026] In some embodiments, at least one connecting hole 13 is provided inside the connecting groove 11, and a connecting rod 22 matching the connecting hole 13 is provided on the connecting block 21. The connecting rod 22 and the connecting block 21 are an integral structure. The connecting rod 22 is bonded and fixed inside the connecting hole 13. The connecting member 2 is an integral structure made of reinforced concrete or an integral structure made of fiberglass.

[0027] In some embodiments, the length of the connecting rod 22 is 0.5 to 1.5 cm longer than the depth of the connecting hole 13, and the end of the connecting rod 22 is provided with a cone 23; wherein, the cone 23 facilitates the insertion of the connecting rod 22 into the interior of the connecting hole 13; at the same time, it can be anchored to the shallow layer of the slope to provide the required anchoring force, while minimizing damage and disturbance to the deep structure of the slope.

[0028] In some embodiments, the bottom of the slope protection brick 1 is uniformly provided with permeable grooves 12, and the periphery of the degradable water-absorbing layer 33 is fixedly provided on the inner side of the slope protection brick 1 above the permeable grooves 12; the permeable grooves 12 facilitate the flow of water and air between the slope protection bricks 1; the periphery of the degradable buffer layer 31 is fixedly provided on the inner side of the slope protection brick 1.

[0029] In some embodiments, the distance between the degradable buffer layer 31 and the top of the slope protection brick 1 is 0.5 to 1.0 cm; the degradable buffer layer 31 and the degradable water-absorbing layer 33 are respectively at a certain distance from the upper and lower ends of the slope protection brick 1, which can reduce the wear of the degradable buffer layer 31 and the degradable water-absorbing layer 33 during stacking and transportation; the perimeter of the degradable buffer layer 31 and the degradable water-absorbing layer 33 are bonded and fixed to the inner side of the slope protection brick 1 with adhesive.

[0030] In some embodiments, the planting soil layer 32 is a planting soil mixed with base fertilizer, seeds and water-retaining agent; wherein the water-retaining agent absorbs hundreds of times its own weight in water and forms a gel, storing excess water during rainfall and slowly releasing it to the plant roots during drought, greatly improving the survival rate of seeds under unpredictable rainfall; wherein the ratio and type of base fertilizer, seeds and water-retaining agent are conventional settings in the art, and this application does not involve improvements to their ratio, so they will not be described in detail.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
