Description

Technical Field

[0001] This utility model relates to a high-strength ecological block for use in river retaining walls. Background Technology

[0002] Utility model patent CN208685913U discloses a concrete composite block, including a concrete composite block body with rounded corners. A planting trough is located at the center of the top of the concrete composite block body, and a support plate is fixed inside the planting trough. Limiting grooves are fixed on both sides of the top of the planting trough, and limiting blocks are fixed on both sides of the bottom of the concrete composite block body. Cylindrical guide holes are formed on the surface of the limiting blocks. This utility model's concrete composite block, with its rounded edges, reduces collisions between concrete composite blocks, maintaining their integrity. Planting vegetation in the planting trough makes the wall composed of concrete composite blocks more aesthetically pleasing and also helps stabilize the soil. The support plate facilitates soil placement and prevents soil leakage. The limiting blocks, embedded in the limiting grooves, connect several concrete composite blocks together. However, this concrete composite block has the problem of insufficient water retention capacity. Utility Model Content

[0003] To address the above shortcomings, the purpose of this utility model is to provide a high-strength ecological block for use in river retaining walls. This block has a stronger water storage capacity and is suitable for drawing water from the base soil of the embankment with higher water content and transporting it to the soil in the planting trough.

[0004] Therefore, this utility model discloses a high-strength ecological block for use in river retaining walls, comprising a block body with inserts and slots that can be fitted with adjacent blocks. The block body has a planting trough extending along the thickness direction, in which soil is injected for planting plants. The feature is that a porous water storage module is closely attached to the rear side of the block body, and the porous water storage module has densely interconnected capillary water storage holes. The porous water storage module is in contact with the soil in the planting trough.

[0005] Preferably, the block body has an embedding groove on its rear side, and the porous water storage module is embedded in the embedding groove.

[0006] Preferably, a baffle with fine mesh is fitted on the rear side of the porous water storage module.

[0007] Preferably, the porous water storage module has a through hole aligned with the planting trough, and the soil enters the through hole.

[0008] Preferably, a fine mesh isolation net is inserted into the through hole.

[0009] Preferably, the porous water storage module is a porous fiber cotton water storage module.

[0010] Preferably, the block body is provided with an insertable water storage tank along the thickness direction, and a porous fiber water storage module is embedded in the insertable water storage tank, with the rear end of the water storage tank connected to the embedded tank.

[0011] Preferably, the main body of the block is made by mixing and pressing waste sludge, slag powder, cement, sand, alkali activator solution and water.

[0012] The beneficial technical effects of this utility model are as follows:

[0013] This invention features a porous water storage module closely attached to the rear end of the planting trough. This module possesses a strong water storage capacity, storing water during periods of abundant rainfall and, during droughts, transferring water back into the soil within the planting trough. The principle behind this is that during droughts, the base embankment soil has a higher water content, while the soil in the planting trough evaporates more easily, becoming drier. In this situation, the porous water storage module can more easily transfer water into the planting trough. Conversely, as water scarcity increases, the porous water storage module also becomes dehydrated. Due to its densely packed and interconnected capillary pores, it can first absorb water from the base embankment soil and then transfer water to the drier soil in the planting trough. This structure is beneficial for plants planted in the early stages, before their roots have penetrated the base embankment soil. The aforementioned structure ensures sufficient moisture for growth in the early stages, and once the roots have penetrated the base embankment soil, they can essentially grow independently, thus significantly increasing the survival rate of the planted plants.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] See attached document Figure 1-5 As shown in Embodiment 1 of this utility model, a high-strength ecological block for use in river retaining walls includes a block body 1. The block body 1 has inserts 2 and slots 3 that can be fitted into adjacent blocks. A planting trough 4 extending along the thickness direction is provided inside the block body 1, into which soil is injected for planting plants. A porous water storage module 5 is attached tightly to the rear side of the block body 1. The porous water storage module 5 has densely interconnected capillary water storage holes and is in contact with the soil in the planting trough 4. In this embodiment, the porous water storage module 5 is a porous fiber cotton water storage module. An embedding groove 6 is located on the rear side of the block body 1, into which the porous water storage module 5 is embedded. The embedding groove 6 facilitates the stable installation of the porous water storage module 5 and relatively isolates it from the compression and erosion of the surrounding soil.

[0022] Refer to Figure 5 As shown, to better prevent squeezing and erosion, a baffle 7 with fine mesh is fitted to the rear side of the porous water storage module 5. The baffle 7 can be attached to the rear side of the porous water storage module 5. The baffle can also be installed using a snap-fit ​​structure, such as a block on the inner wall of the rear port of the embedded groove 6, with an elastic protrusion on the side of the baffle 7 that matches the block. The elastic protrusion is made of elastic steel wire and snaps into the bottom of the block.

[0023] Reference Figure 4 , Figure 5 As shown, in order to enable the plant roots in the planting trough 4 to penetrate directly into the soil of the embankment, the porous water storage module 5 is provided with a through hole 8 aligned with the planting trough 4. A fine mesh isolation net 9 is inserted into the through hole 8. The isolation net 9 plays the role of relatively isolating and protecting the porous water storage module 5, and the soil enters into the through hole 8.

[0024] Referring to Figure 6, this utility model provides a second embodiment, which is basically the same as the first embodiment, except that the following structure is added: the block body 1 is provided with an insertable water storage tank 10 along the thickness direction, and a porous fiber water storage module is embedded in the insertable water storage tank 10. The rear end of the insertable water storage tank 10 is connected to the embedded groove 6, thereby further increasing the water storage capacity.

[0025] In addition, in order to make full use of the waste mud resources from river dredging and improve the strength, the main body of the block described in the above two embodiments is made by mixing and pressing waste silt, slag powder, cement, sand, alkali activator solution and water. The preparation method of the ecological block is as follows: (1) Use sodium hydroxide to prepare sodium silicate solution of the corresponding modulus as alkali activator, and let it stand for later use; (2) Remove foreign objects from the waste silt, determine its moisture content, and then mix the prepared slag powder, cement and building sand into the silt and stir; (3) Calculate the required amount of water according to the set water-cement ratio of 27%, mix the alkali activator solution prepared in step (1) with the required water and pour it into the mixture in step (2), and continue to stir evenly; (4) Pour the stirred mixture into the corresponding mold in layers and vibrate, let it stand for 2-3 days to solidify, demold and put it into the standard curing room for curing for a certain number of days. Compared with existing technologies, this ecological block can recycle a large amount of waste silt from river dredging, producing ecological blocks with a 28-day unconfined compressive strength ≥25MPa. This solves both the difficulties in treating engineering waste silt and the shortage of ecological blocks for river embankments and road widening. This technology uses alkali-activated slag-cement as a cementing material, reusing certain industrial waste, making it environmentally friendly. Furthermore, the ecological blocks prepared by this invention have wide applications, including riverbank protection, highway and railway slopes, mine slope restoration, seawall construction, and reinforcement of roadbeds and building foundations. Finally, the blocks are prepared by casting, a simple method with low equipment investment, and suitable for producing ecological blocks of various appearances. This solution reduces the safety hazards and environmental damage caused by the dumping of engineering waste silt, helps save energy, protects the ecology, and aligns with the green, low-carbon, and sustainable development strategy.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
