Description

Technical Field

[0001] The invention belongs to the technical field of ecological slope protection, and in particular relates to a soil consolidation, flood prevention and ecological storage slope protection. Background Art

[0002] In recent years, with the development of the national economy, large-scale engineering construction (road, building, mining, water conservancy and hydropower) has formed a large number of rock and soil slopes. Improper slope treatment is prone to accidents such as fragmentation, collapse, sliding and even landslides, causing major economic losses and endangering the lives and property of relevant personnel. In order to ensure the stability of the slope and prevent slope collapse and slope erosion and fragmentation, reasonable and appropriate engineering measures need to be taken, such as repairing retaining structures or carrying out slope protection.

[0003] Traditional slope reinforcement measures mostly use stone masonry and sprayed concrete. These methods can improve the stability of the slope to a certain extent, but they destroy the harmony of the ecological environment and hinder material exchange. At present, many ecological slope protection methods are applied to actual projects, most of which use the root system of vegetation for anchoring to improve the stability of the slope. However, the strength of vegetation is limited, and the effect of improving the stability and safety of the slope is not good. Under heavy rainfall conditions, the risk of landslides on the slope is still high, and it is unable to cope with the impact of mountain torrents and heavy rainfall. The mud, stones and runoff washed down by the slope will also cause large-scale pollution. In addition, the current ecological slope protection method requires a large economic investment for vegetation maintenance, and it is necessary to spray and irrigate the slope vegetation in time to ensure the growth and maintenance of vegetation.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0031] Example 1

[0032] like Figure 1 As shown, a soil-solidifying flood-control ecological regulation slope protection comprises a plurality of slope protection brick 1 units, wherein the plurality of slope protection brick 1 units are plugged in up and down and clamped in left and right; the slope protection brick 1 unit comprises a slope protection brick 1 and a water absorption and water guide block 2, the slope protection brick 1 comprises an intermediate baffle 11 and a support plate 12 connected to both sides of the intermediate baffle 11, an insertion port 13 is formed between the intermediate baffle 11 and the support plate 12, and the water absorption and water guide block 2 on the same unit is arranged on a side of the slope protection brick 1 away from the insertion port 13; the water absorption and water guide block 2 of the lower slope protection brick 1 unit is plugged in the insertion port 13 of the upper slope protection brick 1 unit, and the support plates 12 of the upper and lower slope protection brick 1 units are fitted together;

[0033] The thickness of the support plate 12 decreases from the middle to both sides, and a clamping groove is formed between the two support plates 12 on the same side of the upper and lower slope protection bricks 1, and the adjacent slope protection bricks 1 are clamped with each other through the outer wall of the support plate 12 and the clamping groove; the height of the slope protection brick 1 is greater than the height of the water absorbing and guiding block 2; a conical pile 3 is inserted on the slope protection brick 1, and the lower end of the conical pile 3 is inserted into the slope.

[0034] The self-locking structure formed between the slope protection bricks 1 unit can maintain stability in the horizontal and vertical directions, making the slope more stable; and the slope protection can receive the gravel, mud or rainfall runoff rolling down from the top of the slope, and accumulate it inside the slope protection brick 1 unit, reducing the risk of landslides. Compared with traditional slope protection forms (mortar masonry, concrete slope protection), the slope protection of the present invention has better landscape and ecological effects, can store water and utilize the stored water and nutrients carried by the biochar matrix to support the growth and maintenance of vegetation and the ecosystem in the region.

[0035] Example 2

[0036] The difference between this embodiment and the embodiment 1 is that the water-absorbing water-guiding block 2 includes a water-absorbing water-guiding layer and a water-guiding plate 28. The water-guiding plate 28 is arranged below the water-absorbing water-guiding layer. The water-guiding plate 28 is connected with a water-guiding pipe 29. The water-guiding pipe 29 passes through the middle baffle plate 11 and is connected to the surface of the water-absorbing water-guiding block 2 of the lower slope protection brick 1 unit. Therefore, water flows through the upper slope protection brick 1 unit and then enters the water-absorbing water-guiding layer of the next slope protection brick 1 unit, and stores water step by step.

[0037] On the same slope protection brick 1 unit, the height of the water absorbing and guiding block 2 close to the middle baffle 11 is higher than the height of the side away from the middle baffle 11, which is more conducive to the absorption of water from mud and stone and rainfall in the slope protection brick 1.

[0038] The water-absorbing and water-conducting layer includes a gravel layer 21, a water storage matrix layer 22, a sand layer 23, a clay layer 24, a gravel drainage layer 25 and an impermeable layer 26 arranged from top to bottom. The impermeable layer 26 is arranged above the water diversion plate 28. The gravel layer 21 is a crushed stone or pebble with a diameter greater than 2 cm, which is used to reduce the impact of runoff. The water storage matrix layer 22 is made of the same Enteromorpha biochar composite sponge matrix, with a thickness greater than 10 cm, and is mainly used to absorb rainfall runoff to provide nutrients for vegetation growth. The sand layer 23 is a transition layer between the water storage matrix layer 22 and the clay layer. The permeability coefficient of the clay layer is small, so rainwater will gradually accumulate in the sand layer 23 to form a saturated layer. The low oxygen content is conducive to denitrification reaction and promotes the removal of nitrate nitrogen in rainfall runoff. In extreme rainfall conditions, the water in the upper part gradually rises, and the water gradually seeps from the clay layer into the gravel drainage layer 25, which is composed of gravel and crushed stone. The water can quickly seep into the water diversion plate 28, flow into the water diversion pipe 29 along the slope and be discharged step by step downward, avoiding water from entering the slope and causing dangers such as landslides.

[0039] A water retaining layer 27 is provided on one side of the gravel drainage layer 25 close to the slope brick 1. The water retaining layer 27 is located between the anti-seepage layer 26 and the clay layer 24 to prevent water from entering between the slope and the slope. The material of the water storage matrix layer 22 is the same as the Enteromorpha biochar composite sponge matrix 14, has a good water absorption and water storage capacity, and can absorb pollutants such as nitrogen, phosphorus, and heavy metals in rainfall runoff, convert and store nutrients, and provide nutrient support for growing vegetation, wherein the cultivation is prepared to improve the landscape and ecological effects. The water diversion plate 28 and the water diversion pipe 29 are made of PVC thin plates and PVC pipes or stainless steel / cast iron. The water retaining layer 27 can be stacked with tailings silt geotextile bags, and the anti-seepage layer 26 can be made of flexible waterproof geotextile or similar functional materials. The anti-seepage layer 26 and the water retaining layer 27 work together to intercept water as much as possible inside the water-absorbing and water-guiding block, and some of the water that seeps from the anti-seepage layer 26 can be discharged along the water diversion plate to the top of the next water-absorbing and water-retaining block.

[0040] Enteromorpha biochar composite sponge matrix 14 can be made of a material with water storage capacity. In this embodiment, the preparation method of enteromorpha biochar composite sponge matrix 14 is as follows: ethylene glycol, enteromorpha biochar, and deionized water are used in a mass ratio of 60:5:100, and the mixture is continuously stirred and mixed at a speed of 750 rpm at 60°C for 20 minutes. After that, while maintaining the same speed and temperature, 250 parts of diphenylmethane diisocyanate MDI are added dropwise at a constant speed before bubbles are formed. The mixture is poured into a mold, heated at 60°C in a vacuum box for 3 hours, and then cured for 24 hours to obtain a sponge-like material. Under this formula, the enteromorpha biochar composite sponge matrix is ​​lightweight and has good water holding effect and nutrient adsorption capacity. After it is fixed, grass seeds can be sown inside as a soilless cultivation matrix to provide moisture and nutrients for vegetation growth. During rainfall, moisture, nutrients and other pollutants in runoff can be adsorbed, which can purify water quality on the one hand and provide support for vegetation growth on the other. Vegetation grows inside the slope protection brick 1, and the vertical growth of vegetation can be seen from the perspective of the bottom of the slope, achieving a greening effect and achieving a good slope protection landscape effect.

[0041] The conical pile 3 is arranged on the support plate 12 and penetrates the support plate 12 up and down. A through hole is opened on the conical pile 3, and the cuttings of plants are inserted into the through hole. A hole is opened below the conical pile 3, and the hole is located below the slope protection brick 1. The cuttings of plants here are mainly vines. The plants take root in the soil through the through hole, which improves the overall stability of the slope protection brick 1 and the slope, and the through hole can absorb some water.

[0042] The top and inner wall of the slope protection brick 1 are provided with a Enteromorpha biochar composite sponge matrix 14, which is used for vegetation cultivation. The Enteromorpha biochar composite sponge matrix 14 is connected to the slope protection brick 1 through an anchor hook 15, and a wire mesh 16 is provided on the outer surface of the Enteromorpha biochar composite sponge matrix 14 to reinforce and prevent it from falling off.

[0043] A groove 17 is provided on the side of the middle baffle 11 away from the plug port 13, and a plurality of ribs 18 are provided in parallel in the groove 17, and the water absorbing and guiding block 2 is connected to the groove wall of the groove 17. The ribs 18 are provided to improve the strength of the slope protection brick 1, and the design of the groove 17 can increase the storage space for receiving water from the top of the slope, gravel and mud.

[0044] The middle baffle 11 is provided with an overflow hole 111 and a drain hole 112. The overflow hole 111 is higher than the upper surface of the water absorbing and guiding block 2, and the drain hole 112 is lower than the upper surface of the water absorbing and draining block. The overflow hole 111 and the drain hole 112 both have a drainage function. Compared with the water flowing directly from the slope, the baffle slows down the runoff speed before flowing. The water discharged through the drain hole 112 has been adsorbed by the water absorbing and guiding layer, which can purify the water quality; if the rainwater is large enough, it can be directly discharged through the overflow hole 111.

[0045] An anti-slip pile 4 is arranged at the bottom of the middle baffle 11 and inserted into the slope soil to improve the anti-slip ability of the slope protection brick 1.

[0046] The height of the same slope protection brick 1 decreases gradually from top to bottom.

[0047] The specific implementation steps are:

[0048] 1. Pre-cut the Enteromorpha biochar composite sponge matrix into appropriate size.

[0049] 2. Cut and level the land, and adjust the slope to keep it flat.

[0050] 3. Place the slope protection bricks 1, overlap them in a honeycomb pattern from the foot of the slope upwards, insert the anti-slide piles 4 into the slope soil, lay the anti-seepage layer 26, the water diversion plate 28, insert the water diversion pipe 29, and lay the anti-seepage layer 26.

[0051] Fourth, the water-absorbing and water-conducting layer is laid inside the slope protection brick 1 and filled in layers. A gauze is placed at the drainage hole 112 to filter and block the silt, and ensure that the overflow hole 111 is not covered above the water-absorbing and water-conducting layer.

[0052] Fifth, place and lay out the Enteromorpha biochar composite sponge matrix 14, and fix it with anchor hooks 15 and wire mesh 16, sow grass seeds inside the Enteromorpha biochar composite sponge matrix 14 and the water storage matrix layer 22 of the water absorption and water conduction layer, and spray water for maintenance.

[0053] During the rainfall period, rainwater forms surface runoff, gradually flows downward from the top of the slope, passes through the fillers of the water-absorbing and water-conducting layer, and is adsorbed inside the water storage matrix layer 22. Excess water seeps downward, flows downward through the water diversion plate 28 and the water diversion pipe 29, and is gradually absorbed by the slope protection brick 1 unit. Part of the rainwater accumulates inside the water-absorbing and water-conducting layer. After the water level rises to the overflow hole 111, it flows downward and absorbs part of the overflow and rainwater through the water storage matrix layer 22. The silt and gravel particles carried by the runoff will gradually settle on the surface of the water-absorbing and water-conducting layer. Part of the rainwater can be collected inside the conical pile 3 for rainwater collection.

[0054] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0055] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
