[0046] The slope protection bricks are made of recycled concrete and two types of fibers. The specific material formula is as follows: 30-40 parts recycled aggregate, 30-40 parts recycled sand, 5-10 parts steel fiber, 5-10 parts composite bamboo fiber, 10-20 parts cement, 2-5 parts adhesive, 0.3-0.8 parts water-reducing agent, 0.5-3 parts mineral pigment, 0.3-0.5 parts permeable agent, and 10-20 parts water. The adhesive is a modified epoxy resin, silicone adhesive, or acrylic adhesive, which has good flexibility, toughens rigid cement to prevent cracking, is flame-retardant and heat-resistant, and extends the service life. The recycled aggregate comes from construction waste solid materials with a particle size of 1-5mm. The recycled sand comes from construction waste soil with a particle size of less than 0.5mm. The cement is high-strength silicate cement with a strength grade of not less than 52.5. The composite bamboo fiber has a diameter of 1-2 mm, a length of 25 mm, a tensile strength of 300 MPa, and a density of 0.5 g / cm³. 3 The elastic modulus is 20 GPa. The water-reducing agent is a polycarboxylate water-reducing agent.

[0047] The specific working process and principle of this utility model are as follows:

[0048] On the slope requiring slope protection, two bricks, 1 and 2, are connected together using wedge-shaped platform structure 9 and wedge-shaped groove structure 10 to form a brick unit. Then, connecting block 4, connecting block 5, connecting block 6, and connecting block 7 are respectively embedded and connected to the brick unit using wedge-shaped groove structure 10 and wedge-shaped platform structure 9. The connection unit is achieved by swapping the top and bottom of connecting blocks 4, 5, 6, and 7, thus connecting them to the brick unit. See [link to specific connection structure] for details. Figure 2 The process continues until the brick units and connecting units are assembled to a certain height on the slope. Finally, the brick units and connecting units are anchored along the slope by a number of anchor bolts that are sequentially inserted into them. Specifically, the anchor bolts are sequentially passed through the connecting holes of brick 1 in the brick unit, the connecting hole of connecting block 2 5, and the connecting hole of brick 1 in another brick unit, and the anchor bolts are tightened. The anchor bolts are then sequentially passed through the connecting holes of brick 2 2 in the brick unit, the connecting hole of connecting block 2 5, and the connecting hole of brick 2 2 in another brick unit, and the anchor bolts are tightened. At the bottom of the slope, brick 1 1 and brick 2 2 are connected by anchor bolts inserted into the connecting holes of connecting block 4 7.

[0049] See Figure 2 A filler block 12 is set between two connecting blocks 3 6, two filler blocks 12 are set between connecting blocks 3 6 and connecting blocks 4 7, and a filler block 12 is set between two connecting blocks 4 7, so that the thickness of connecting blocks 1 4, connecting blocks 2 5, connecting blocks 3 6 and connecting blocks 4 7 after connection is the same as the thickness of brick 1 1 and brick 2 2.

[0050] The brick unit and the connecting unit are modularly combined, and the brick one, brick two and the connecting unit are interlocked with each other through the wedge-shaped platform structure and the wedge-shaped groove structure, which makes the connection convenient and reliable. The brick unit and the connecting unit are further anchored and connected by high-strength anchor bolts, which makes the overall strength of the slope protection bricks higher and the slope protection effect better.

[0051] After the connecting unit and the brick unit are connected, when the rainfall is heavy, the rain first reaches the connecting unit and the brick unit. The connecting unit and the brick unit resist the erosion of the slope by the rain. The rain flows from the slope into the water channel 8 on the connecting block 1 4 and the connecting block 3 6 respectively, and flows down along the water channel 8 until it flows into the drainage hole 81 respectively. The rainwater flowing into the drainage hole 81 flows into the planting cavity 3 through the connecting hole of the brick 1 1 and the brick 2 2 respectively, irrigating the vegetation in the planting cavity 3 of the brick 1 1 close to the connecting block 1 4. It seeps into the slope soil and into the adjacent other planting cavities 3 until all the vegetation in the planting cavity 3 is irrigated. At the same time, the rain flows into the slope through the water channel 8 of the connecting block 4 7 and the drainage hole 81, avoiding the erosion of the slope by the rain.

[0052] Connecting block 1 (4) and connecting block 3 (6) are equipped with water diversion channels (8). The water diversion channels (8) are equipped with drainage holes (81) that communicate with the planting cavities (3) on brick 1 (1) and brick 2 (2). Through the setting of water diversion channels and drainage holes, the slope is resisted from the erosion of the slope by heavy rainfall, rainwater is drained in time, rainwater is prevented from accumulating on the slope, and the slope protection effect of the slope protection bricks is improved.

[0053] During the dry season, irrigation water can be introduced into the water channel 8 to irrigate the vegetation in the planting cavity 3. The utilization rate of irrigation water is high, which improves the planting effect of vegetation and further enhances the slope protection effect of the slope protection bricks.

[0054] The specific composition ratio of the slope protection bricks is as follows: 35 parts recycled aggregate, 35 parts recycled sand, 6 parts steel fiber, 6 parts composite bamboo fiber, 15 parts cement, 3 parts adhesive, 0.5 parts water-reducing agent, 1.5 parts mineral pigment, 0.5 parts permeable agent, and 25 parts water.

[0055] The preparation method of slope protection bricks is as follows: Weigh the recycled aggregate, recycled sand, steel fiber, composite bamboo fiber, cement, adhesive, water-reducing agent and permeable agent according to the formula and mix them evenly in a mixer. After mixing the mineral pigment with water, add it to the mixed material in multiple batches. After mixing for 20-30 minutes, pour the mixed material into a mold with reinforcing ribs to remove air bubbles in the recycled concrete. After standing for 5-7 hours, demold and obtain the connecting unit and brick unit after curing.

[0056] At the structural level, each brick unit is deeply embedded with the wedge-shaped groove structure 10 and the wedge-shaped platform structure 9 to form multiple small connecting units. The connecting units and the brick units are connected to form an integral unit through the wedge-shaped groove structure 10 and the wedge-shaped platform structure 9. The connecting units are anchored with high-strength bolts, which greatly improves the strength of the brick slope protection bricks.

[0057] The anchor holes enhance the bond strength between the slope bricks and the soil, effectively preventing debris flows and landslides. A water channel 8 is installed on the connecting body to prevent excessive rainfall from accumulating on the brick surface during heavy rains, thus reducing the impact of rainfall on the strength of the slope bricks.

[0058] In terms of constituent materials, adding steel fibers to the concrete of the vegetation slope protection bricks helps improve the later strength and toughness of the matrix, effectively hindering the expansion of micro-cracks and the formation of macro-cracks within the brick surface, significantly improving the tensile, bending, impact, and fatigue resistance of the brick surface, and exhibiting good ductility. By adding composite bamboo fibers, the amount of steel fibers is reduced while ensuring strength, lowering the concrete density, maintaining permeability channels, and overcoming the problems of poor fluidity and low density caused by adding steel fibers to the brick surface. By mixing steel fibers and composite bamboo fibers, fibers of different sizes and properties play a reinforcing and toughening role in different loading stages and structural layers of the permeable brick surface, achieving a step-by-step crack prevention and performance complementarity, giving the slope protection bricks excellent comprehensive mechanical properties. Recycled concrete has the characteristic of high porosity, and the mechanical properties of the bricks can be significantly improved after adding different fibers, thus improving the environmental adaptability of the slope protection bricks.

[0059] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
