[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0031] The present application provides a kind of vegetation concrete grid and ecological interlocking block combination slope protection structure, comprising slope protection grid 11 by vegetation concrete pouring and the multiple ecological interlocking blocks 12 paved in slope protection grid 11. The following will be described in detail.
[0032] As shown in the drawings, Figure 1 As shown, the slope protection grid 11 comprises longitudinal grid bars 11.1 and transverse grid bars 11.2, which are both cast by the vegetation concrete.
[0033] In some embodiments of the present application, the vegetation concrete is constructed by on-site mixing and casting, and the vegetation concrete 10 is mixed by using cement, water and gravel in a specified ratio, and using a concrete surface reinforcing agent as an admixture. The mixing ratio of the vegetation concrete is as follows: cement: water: gravel = 1:0.25:4.5. In addition, the vegetation concrete is mixed with grass seeds by using a concrete surface reinforcing agent as an admixture and adding grass seeds. For example, the grass seeds are Cynodon dactylon grass seeds.
[0034] In some embodiments of the present application, the vegetation concrete does not use medium sand and coarse sand. The mixed concrete does not have medium sand and coarse sand filling in the surface and interior of the vegetation concrete, and can leave more pores as space and path for the extension of plant roots. The plant roots can replace the support of medium and coarse sand fine aggregate, and provide a path for the extension of plant roots to be closely combined with the surrounding soil. The connection of the plant roots can form a whole with the slope soil body of the slope vegetation concrete structure, and further strengthen the stability of the slope.
[0035] The cement used in the vegetation concrete mixed by using cement, water and gravel in a specified ratio is ordinary portland cement with a strength grade of 42.5. In the initial setting to final setting stage of the vegetation concrete without fine aggregate, the bonding strength between the coarse aggregate of the vegetation concrete is guaranteed. For example, the amount of cement used per cubic meter of vegetation concrete is 360 kg. The gravel used for mixing the vegetation concrete is, for example, well-graded gravel with a particle size of 15-30 mm. The flaky gravel should be removed, so that the different particle sizes of the gravel can maintain effective “bite force” through reasonable grading, support each other, and ensure the stability of the concrete structure. For example, the amount of well-graded gravel with a particle size of 15-30 mm used per cubic meter of vegetation concrete is 1620 kg. For example, the amount of clean water used per cubic meter of vegetation concrete is 90 kg. The admixture used in the vegetation concrete is a concrete surface reinforcing agent. For example, 1 kg of the concrete surface reinforcing agent is added per cubic meter of vegetation concrete during the mixing of the vegetation concrete, and the vegetation concrete is uniformly mixed. The vegetation concrete can maintain a large strength in the initial setting to final setting stage through the concrete surface reinforcing agent, and improve the stability of the vegetation concrete structure. After the vegetation concrete is mixed, for example, 100 g of Cynodon dactylon grass seeds are added per cubic meter of vegetation concrete, and the vegetation concrete is uniformly mixed again, so that the grass seeds are uniformly mixed into the vegetation concrete, and the preparation of the vegetation concrete is completed.
[0036] In addition, in some embodiments of this utility model, the slope protection grid 11 formed by pouring vegetated concrete is constructed by first pouring vegetated concrete to form the longitudinal grid bars 11.1 and the transverse grid bars 11.2 of the slope protection grid 11, specifically including:
[0037] At intervals of N 10 meters (e.g., 6m) along the longitudinal and transverse sides of each slope, trenches 50cm wide and 50cm deep are excavated for pouring vegetated concrete slope protection grid 11. Side formwork is erected in each trench. The formwork is made of steel plate and is, for example, 65cm high, with 5cm of the formwork inserted into the soil layer for anchoring and fixing the formwork. The formwork is higher than the slope surface by a specified distance (e.g., 10cm) to support the pouring of vegetated concrete above the slope surface.
[0038] The mixed vegetated concrete was first poured to form the longitudinal grid 11.1, followed by the transverse grid 11.2. Pouring was done in sections from bottom to top to prevent concrete slippage and segregation due to excessively steep slopes. After the vegetated concrete reached its final set, it was watered every specified number of days (e.g., every two days) for curing. This not only improved the concrete strength but also promoted the growth of grass seeds in the pores of the vegetated concrete, filling these pores promptly.
[0039] Once the planted concrete reaches the specified strength and has cured, the concrete formwork is removed, and as follows: Figure 1 As shown, ecological interlocking blocks 12 are laid in each slope protection grid 11, for example, 6m*6m, enclosed by longitudinal grid 11.1 and transverse grid 11.2.
[0040] In some embodiments of this utility model, such as Figure 2 As shown, the ecological interlocking block 12 includes a crossbeam 12.2 and side beams 12.3 located at both ends of the crossbeam 12.2. The side beams 12.3 are perpendicular to the crossbeam 12.2 and are integrally formed. Both ends of the side beam 12.3 are provided with concave fitting portions 13, wherein each fitting portion 13 is a right-angled trapezoid. The upper bottom surface 13.1, the lower bottom surface, and the two waist surfaces 13.2 of the fitting portion 13 are all rectangular, and the other two surfaces of the fitting portion 13 are trapezoidal surfaces 13.3. The upper bottom surface 13.1 of the fitting portion 13 is parallel to the outer surface of the side beam 12.3 away from the crossbeam 12.2. One of the waist surfaces 13.2 of the fitting portion 13 is flush with the end face of the corresponding end of the side beam 12.3, and the other waist surface 13.2 is an inclined surface. The vertical distance between the junction of the upper bottom surface 13.1 and the other waist surface 13.2 and the crossbeam 12.2 is equal to the length of the lower bottom surface of the fitting portion 13. For the same ends of the two side beams 12.3, the distance between the upper bottom surfaces 13.1 of the fitting portions 13 is equal to twice the width of the crossbeam 12.2.
[0041] In this embodiment, the interlocking part 13 is integrally formed with the side beam 12.3. The concave interlocking part 13 allows the eco-interlocking blocks 12 to be laid in a wedge-fitting and interlocking manner, forming a... Figure 3 The form shown ( Figure 3 This only shows a portion of the eco-interlocking building blocks 12, not all of them, but the laying pattern can be observed. Figure 3 (As shown).
[0042] In some embodiments of the present invention, in order to better protect the slope, such as Figure 4 As shown, both the crossbeam 12.2 and the side beam 12.3 are provided with multiple through-holes 12.1 for planting grass. Grass seeds, exemplarily Bermuda grass seeds, are placed in the through-holes 12.1. The grass seeds have space and a path to grow downwards through the space of the through-holes 12.1, and together with the ecological interlocking blocks 12, they play a role in slope protection and soil reinforcement. At the same time, the interlacing of grass roots tightly connects the planted concrete slope protection grid 11 and the ecological interlocking blocks 12 into a whole, playing a synergistic role in reinforcing the slope, preventing slope instability and soil erosion.
[0043] In some embodiments of this utility model, in order to facilitate the replacement of the ecological interlocking blocks 12 when adjustments to the laid blocks are needed later, such as... Figure 5 As shown, the outer side of the side beam 12.3 away from the crossbeam 12.2 is provided with a groove 12.4, and an auxiliary groove 12.5 is provided in the groove 12.4. The auxiliary groove 12.5 extends into the crossbeam 12.2. Workers can easily lift the entire ecological interlocking block 12 by inserting their hands into the two grooves 12.4.
[0044] In some embodiments of this utility model, in order to more easily lift the eco-interlocking block 12, such as... Figure 5 As shown, the side beam 12.3, the cross beam 12.2, and the outer periphery of the fitting part 13 are provided with a plurality of through ball bearing holes 12.6, and the ball bearing holes 12.6 are in the shape of a semi-frustum. The rotation axis of the ball bearing hole 12.6 is perpendicular to the trapezoidal surface 13.3 and passes through the side beam 12.3. Figure 6The diagram illustrates how two adjacent interlocking eco-blocks 12 form a complete frustum of a hole by interlocking semi-circular holes. A ball bearing 12.7 is inserted into this complete frustum of a hole. Before inserting their hands into the two grooves 12.4, workers insert the ball bearing 12.7 into each hole forming a complete frustum of a hole. The ball bearing 12.7 can be gently tapped into the ball bearing hole 12.6 to further embed itself. Due to the special semi-circular shape of the ball bearing hole 12.6... (That is, the diameter of the complete frustum-shaped hole gradually decreases towards the ground) When the replacement eco-interlocking block 12 and its adjacent eco-interlocking blocks 12 are lifted, the diameter of the frustum-shaped hole away from the ground will increase. Under the action of the ball bearing 12.7, the bottom wall of the ball bearing hole 12.6 of the eco-interlocking block 12 will drive the ball bearing 12.7, giving the ball bearing 12.7 an upward force. Ultimately, the replacement eco-interlocking block 12 can be easily lifted.
[0045] In summary, the combined ecological slope protection structure of this utility model, consisting of "vegetated concrete slope protection grid + ecological interlocking blocks," enhances the load-bearing capacity of the blocks compared to traditional ordinary concrete grid slope protection. This effectively ballasts the soil on steep slopes. Compared to ordinary concrete slope protection grids and solid ballast blocks, the "vegetated concrete slope protection grid + ecological interlocking blocks" provide both gravity ballast and soil stabilization through plant roots, thus improving slope stability. Furthermore, the vegetation protects and restores the ecological environment. As the plant roots continue to grow, the soil is reinforced from the source, preventing soil erosion and slope instability.
