Description

Technical Field

[0001] The present invention relates to the technical field of soil and water conservation, and particularly to a biological brick with a plant drought resistance function and a production process thereof. Background Art

[0002] Plants are often planted on the banks of rivers, lakes and reservoirs for ornamental purposes or for soil and water conservation. Especially for the drawdown zone, also known as the water level fluctuation zone, water level rise and fall zone, drawdown belt, etc., which refers to a special area of land that is periodically exposed above the water surface due to seasonal water level fluctuations in rivers, lakes and reservoirs, becoming land, and belongs to the wetland category. When there are seasonal water level fluctuations and periodic water storage in rivers, lakes and reservoirs, a water-land environment transition zone with alternating dry and wet conditions is formed on the river bank. Plants in this zone often die due to difficulty in adapting to environmental changes. Before the formation of the drawdown zone, the vegetation growing on both sides of the reservoir area was a natural ecological barrier, playing a certain role in intercepting and filtering pollution from the reservoir bank, especially agricultural non-point source pollution. A considerable part of the nitrogen, phosphorus, etc. carried by surface runoff was digested and absorbed by the vegetation, preventing it from entering the reservoir water body. After the formation of the drawdown zone, industrial and domestic water will be polluted, the water self-purification capacity will decline, and more pollutants will enter the water body, causing losses to aquatic economic organisms and landscape values. In addition, environmental problems such as soil erosion, bank slope collapse and water and soil loss in the drawdown zone are also very prominent, and effective solutions need to be taken as soon as possible to repair the vegetation and restore the original ecological landscape.

[0003] At present, the protection of plants in the drawdown zone mainly relies on biological bricks installed on the bank or other slope protection bricks for fixing plants. It mainly focuses on the selection of plants along the reservoir bank. By cultivating plants that are resistant to waterlogging and drought on the river bank, the bank foundation is stabilized to maintain the ecological function of the drawdown zone. However, the current slope protection bricks can only play the role of stabilizing the river embankment and cannot provide water for plants during the dry season, resulting in a relatively high plant mortality rate during the dry season and interrupting the ecological restoration process of the drawdown zone.

[0004] Patent CN217556590U discloses a combined soil and water conservation bio - brick, including a bio - brick body, positioning columns and a water storage tank. Positioning columns are installed on the outer side of the bio - brick body. Activity cavities are opened on the front and back of the positioning columns. A positioning plate is installed on the side of the bio - brick body away from the positioning columns. A water accumulation tank is opened on the top of the bio - brick body, and a water storage tank is opened inside the bio - brick body. In this utility model, by opening activity cavities on the front and back of the positioning columns, when combining the bio - bricks, the locking block is pressed. The locking block moves inside the moving groove and squeezes the return spring. When the bio - bricks are horizontally spliced, the installation block is fitted and installed inside the installation groove. Due to its own elastic force, the return spring makes the locking block snap into the locking hole, realizing the stable connection between two groups of bio - bricks. The convenient installation and disassembly of the bio - bricks provide convenience for the users and enhance the practical performance. However, after long - term use, this bio - brick is easily corroded or affected by other factors, resulting in reduced stability, unable to protect plants well, and inconvenient for fertilizing and watering plants, with relatively large limitations. Summary of the Invention

[0005] In view of the above - mentioned problems, the present invention provides a bio - brick with a plant drought - resistance function and its production process.

[0006] The technical solution of the present invention is as follows:

[0007] A bio - brick with a plant drought - resistance function, including a brick body. Openings are symmetrically arranged on the upper and lower sides of the brick body. Interlocking bayonets are arranged inside the openings. On the brick body located on both sides of the interlocking bayonet, there are clamping blocks corresponding to the interlocking bayonet for clamping. The two clamping blocks on the same side with opposite positions on adjacent two brick bodies are clamped inside the interlocking bayonet. Each brick body is vertically interlocked and clamped with each other through the interlocking bayonet and the clamping block. The middle part of the brick body is hollow - set to form a planting area. Longitudinal holes are arranged at the bottom of the brick body on the front and back sides of the planting area, and transverse holes are arranged at the bottom of the brick body on the left and right sides of the planting area;

[0008] On the front and back sides of the brick body in the planting area, a number of limiting sliders are symmetrically arranged. The limiting sliders are slidably connected with the first limiting sliding grooves arranged inside the brick body. At the end of the first limiting sliding groove on one side of the interlocking bayonet, there is a first biological glue seal, which is connected to the end of the limiting slider. A second limiting sliding groove is arranged inside the outer end face of the clamping block, and a second biological glue seal is arranged outside the second limiting sliding groove. When the clamping blocks on adjacent two brick bodies are clamped with the interlocking bayonet of this brick body, the second biological glue seals on adjacent two brick bodies are respectively docked with the two first biological glue seals inside the interlocking bayonet.

[0009] Furthermore, a placement groove for placing water pipelines is provided on the side of the clamping block. The placement grooves on the front and rear two clamping blocks on the same side of the same brick body are longitudinally aligned. After the adjacent two clamping blocks on the adjacent two brick bodies are butted, the cross-sections of the placement grooves on the adjacent two clamping blocks form a circle.

[0010] Explanation: The setting of the placement groove facilitates the laying of water injection pipelines inside the biological brick, which is beneficial to the growth of plants in the planting area. Moreover, the water injection pipeline can communicate with any position of the longitudinal holes or transverse holes through the placement groove.

[0011] Furthermore, the planting area is rectangular. The cross-section of the longitudinal hole is set as a superior bow with an angle of 260 - 300°, and the transverse hole is rectangular.

[0012] Explanation: By optimizing the structures of the longitudinal holes and transverse holes, the contact area between the bricks and the soil is increased, the water absorption efficiency of the bricks is improved, and it is also beneficial to the laying of water injection pipelines.

[0013] Furthermore, there are 2 limiting sliders respectively arranged in the front and rear, and the 2 limiting sliders on the same side are symmetrically arranged with respect to the longitudinal hole.

[0014] Explanation: Through the setting of the limiting sliders, after the plants grow inside the planting area, the plant branches can push the limiting sliders to slide, thus completing the clamping of the limiting sliders and the second limiting chute. As a result, the connection strength of the biological bricks after being used for a period of time is enhanced, and the cracking or overall loosening at the joints of the biological bricks is avoided.

[0015] Furthermore, an arc transition surface is provided at the bottom of the limiting slider. The front - rear length of the brick body is 1 - 1.5 m, the left - right length of the brick body is 0.8 - 1 m. The depth of the first biological glue seal inside the first limiting chute is 5 - 10 cm, the depth of the limiting slider embedded in the first biological glue seal is 4 - 6 cm, the depth of the second limiting chute is 5 - 7 cm, and the thickness of the second biological glue seal is 1 - 2 cm.

[0016] Explanation: By optimizing the depths of the limiting chute and the biological glue seal, the optimal connection degree is achieved. The biological glue seal is gradually decomposed over time, and this is exactly the growth period of the plant branches. Thus, the plant branches can smoothly push the limiting sliders, and at the same time, the tightness inside the limiting chute in the early stage when the biological bricks are placed, that is, when the plants are just planted, is ensured, and foreign matters are prevented from entering the inside of the limiting chute.

[0017] The production process of a biological brick with a plant drought - resistance function according to any one of the above, includes the following steps:

[0018] S1. Selection of raw materials:

[0019] S1-1, Selection of raw materials for brick body and limit slider: The raw materials used for the brick body and the limit slider are the same. By weight, take 15 - 20 parts of waste red bricks, 10 - 13 parts of diatomite, 5 - 8 parts of clay, 1 - 2 parts of shell powder, mix and grind them, and then pass through a sieve of 80 - 100 meshes to obtain a mixed powder. Add 0.5 - 1 part by weight of sodium silicate and 85 - 90 parts by weight of water to the mixed powder, stir and mix for 1 - 2 h to obtain a mixed slurry;

[0020] S1-2, Selection of raw materials for biological glue seal: The raw materials used for the first biological glue seal and the second biological glue seal are exactly the same, and the preparation methods are also exactly the same. By weight, take 10 - 12 parts of plant straw, 4 - 6 parts of starch glue, 1 - 2 parts of glycerol, 1 - 2 parts of liquid paraffin, 0.05 - 0.1 part of citric acid, and 0.5 - 1 part of biological fertilizer;

[0021] S2, Preparation of brick body and limit slider: Put the mixed slurry obtained in step S1-1 into the molds of the brick body and the limit slider respectively. Then spray nano-zinc oxide dispersion liquid and titanium dioxide sol on the surface of the mixed slurry, and then put the molds into a kiln furnace. Heat up at a heating rate of 3 - 5 °C / min to 250 - 350 °C, keep warm for 0.5 - 1 h, continue to heat up at a heating rate of 4 - 6 °C / min to 650 - 750 °C, keep warm for 1 - 2 h, continue to heat up at a heating rate of 1 - 2 °C / min to 1050 - 1100 °C, keep warm for 0.2 - 0.5 h, and then cool down to room temperature with the furnace to take out the molds to obtain the brick body and the limit slider;

[0022] S3, Preparation of biological glue seal: Place the plant straw in a water bath crucible and heat it in a water bath at 90 - 100 °C for 1 - 2 h. Take it out and dry it at 40 - 50 °C, crush it and pass through a sieve of 40 - 50 meshes to obtain plant straw powder. Mix the plant straw powder with the remaining raw materials in step S1-2, stir for 1 - 2 h to obtain a mixed glue seal liquid. Put the mixed glue seal liquid into a mold for high-temperature molding. The molding temperature is 150 - 160 °C, the molding time is 10 - 12 min, and the molding pressure is 5 - 6 MPa. After demolding, obtain the biological glue seal;

[0023] S4, Assembly: Install the limit slider prepared in step S2 inside the first limit chute of the brick body. Then preheat the biological glue seal prepared in step S3 and pour it into the first limit chute. After the biological glue seal cools, it serves as the first biological glue seal to fix the limit slider. Then coat the surface of the second limit chute with the preheated biological glue seal, and after cooling, it serves as the second biological glue seal.

[0024] Further, the spraying amount of the nano-zinc oxide dispersion liquid and the titanium dioxide sol in each mold in step S2 is 2-3% of the weight of the mixed slurry in the mold, the mass ratio of the nano-zinc oxide dispersion liquid to the titanium dioxide sol is 1:2, the particle size of the nano-zinc oxide particles in the nano-zinc oxide dispersion liquid is 40-50 nm, and the content of the nano-zinc oxide particles in the nano-zinc oxide dispersion liquid is 15-20%.

[0025] Note: By optimizing the spraying amounts of the nano-zinc oxide dispersion liquid and the titanium dioxide sol, the prepared bio-bricks and the limit sliders can be prevented from being oxidized.

[0026] Further, in step S1, the plant straw is one or more of wheat straw, rice straw, and peanut straw, and the bio-fertilizer is one or more of nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer.

[0027] Note: By optimizing the component contents in the bio-glue seal, the bio-glue seal has complete degradability, and the raw materials are convenient to obtain. The utilization of waste saves resources. Most importantly, by adding bio-fertilizer, various bio-fertilizers can be continuously released during the slow degradation process of the bio-glue seal, which plays a good role in promoting the growth of plants in the planting area.

[0028] Further, the preheating temperature in step S4 is 50-60 °C.

[0029] Note: By preheating, the bio-glue seal is maintained at a certain fluidity so that it can flow in the limit chute and finally form.

[0030] The beneficial effects of the present invention are:

[0031] (1) The present invention provides a bio-brick with a plant drought resistance function and its production process. The bio-brick can be laid on the soil of the river bank slope, and the connection between the brick bodies is stable, thereby improving the stability of the slope. At the same time, plants can be planted in the bio-brick, and the contact area between the brick and the soil is increased through various holes penetrating the bio-brick body, improving the water absorption efficiency of the brick, providing a good water and soil environment for plants in the drawdown zone during the dry period, thereby improving the efficiency of ecological restoration in the drawdown zone, and at the same time being beneficial to preventing soil erosion in the river bank area and reducing the pressure on the treatment of river and reservoir pollution.

[0032] (2) The bio-brick of the present invention can facilitate the layout of the water injection pipeline inside the bio-brick through the setting of the placement groove, which is beneficial to the growth of plants in the planting area. The water injection pipeline can communicate with any position of the longitudinal hole or the transverse hole through the placement groove. By optimizing the structures of the longitudinal hole and the transverse hole, the contact area between the brick and the soil is increased, the water absorption efficiency of the brick is improved, and at the same time, it is beneficial to the layout of the water injection pipeline.

[0033] (3) The biological brick of the present invention correlates the growth cycle of plants with the connection firmness of the device. Through the setting of the limit slider, after the plants in the planting area grow, the plant branches can push the limit slider to slide, thereby completing the clamping of the limit slider and the second limit chute, so that the connection strength of the biological brick is enhanced after being used for a period of time, avoiding cracking at the connection of the biological brick or overall loosening. By optimizing the depth of the limit chute and the biological glue seal, the optimal connection degree is achieved, and the biological glue seal is slowly decomposed over time. At this time, it is also the growth period of the plant branches, so that the plant branches can smoothly push the limit slider, and at the same time, it also ensures the tightness inside the limit chute in the early stage when the biological brick is placed, that is, when the plants are just planted, to prevent sundries from entering the limit chute.

[0034] (4) The production process of the biological brick of the present invention optimizes the component content in the biological glue seal, making the biological glue seal completely biodegradable, with convenient raw material procurement and waste utilization saving resources. Most importantly, by adding bio-fertilizer, the biological glue seal can continuously release various bio-fertilizers during the slow degradation process, playing a good role in promoting the growth of plants in the planting area.

[0092] Working principle: The following describes the detailed usage method and working principle of the biological brick of the present invention in conjunction with the method of the present invention.

[0093] First, lay multiple biological bricks flat on the river bank slope that needs soil and water conservation. As shown in Figure 4 , the clamping blocks 2 of two adjacent brick bodies 1 are clamped side by side in the interlocking bayonet 12 of the other brick body 1 to complete the fixation of 3 adjacent biological bricks. By analogy, the fixation of multiple biological bricks in an entire area is completed. When installing the biological bricks, the water injection pipeline needs to be laid. According to the needs, select the direction of the water injection pipeline and set the water injection pipeline in different placement grooves 23, longitudinal holes 14, and transverse holes 15, so that the water injection coverage area of the water injection pipeline can cover all the plants in the biological bricks. As shown in Figure 5The layout of the water injection pipeline is shown as follows;

[0094] After the biological bricks are laid out, the required plants are planted in the planting areas 13 of each brick body 1. Since the plant rhizomes required to be planted in the biological bricks of the present invention need to have a certain toughness and thickness to complete the pushing of the limiting slider 3, it is therefore best to choose to plant arbor and shrub plants. After planting, as the plants grow, the rhizome parts become thicker. During the growth process, the rhizomes slide the limiting slider 3 in the first limiting chute 16. At the same time, according to the time line calculation at this time, a part of the first biological glue seal 4 has been decomposed, and the second biological glue seal 22 has been gradually completely decomposed and dissipated due to its thinner thickness. The components of the biological fertilizer in the first biological glue seal 4 and the second biological glue seal 22 fall into the soil as a supplement to the nutrients required by the plants, and the remaining part in the first biological glue seal 4 continues to nourish the plants as subsequent nutrients, and the remaining part can no longer block the limiting slider 3. Therefore, the limiting slider 3 can slide into the second limiting chute 21 to complete the limiting fixation between two adjacent biological bricks, so that the connection strength of the biological bricks after being used for a period of time is enhanced, and the cracking or overall loosening at the connection of the biological bricks is avoided;

[0095] It should be noted that: 90% of the total mass of the two biological glue seals will be converted into carbon dioxide within 3 years.

[0096] Experimental example

[0097] In order to verify the actual use effect of the biological bricks of the present invention, experimental research was first carried out on them. The biological bricks prepared in Examples 5, 7, and 9 were selected for the experiment and compared with commercially available biological bricks made of conventional ceramics. The comparison results are as follows:

[0098] It was found through comparison that when the biological bricks were placed for one year, the growth rate of the plants in the biological bricks in Examples 5, 7, and 9 of the present invention was about 5% faster, and cracks appeared on the surface of the commercially available biological bricks made of conventional ceramics, while only a small number of fine cracks appeared on the surface of the biological bricks in Examples 5, 7, and 9 of the present invention; at 3 years, obvious cracks appeared on the surface of the commercially available biological bricks made of conventional ceramics and some were severely damaged, and the connectivity and integrity decreased, while although cracks appeared on the surface of the biological bricks in Examples 5, 7, and 9 of the present invention, the overall connectivity was still good and the plant growth state was also significantly better.
