Description

Technical Field

[0001] The invention belongs to the technical field of environmental treatment equipment, and in particular relates to a flexible anti-seepage resistance structure. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies and more than 10 commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and implemented contaminated soil treatment and remediation plans, thus forming an emerging soil remediation industry. Contaminated soil contains various elements, especially heavy metal lead, which can easily make it very difficult for plants to survive in the soil. The traditional remediation method is to repair the soil through a remediation device to facilitate the survival of plants, etc., but the remediation device has some disadvantages: First, the general remediation device uses exogenous additions such as organic matter, zeolite and phosphate. Additives are used to adjust and change the physical and chemical properties of heavy metals in the soil, causing them to produce a series of reactions such as precipitation, adsorption, ion exchange, humification and redox, but the placement of additives is inconvenient. They are all manually buried by digging pits with shovels, and it is impossible to place them in sections at equal intervals, which is very troublesome and the repair range cannot be guaranteed. Secondly, it is inconvenient to quickly turn the fields and bury the materials after adding the additives, and they are easily exposed to the outside, resulting in low efficiency in the repair process of the materials. Thirdly, after adding the additives, the soil that needs to be repaired cannot be loosened by itself, which results in a slow speed for the materials to adsorb or exchange and repair the soil, and a long repair process.

[0003] Nowadays, soil barrier covering remediation technology is a common technical means for the treatment of contaminated sites and is widely used. Its technical principle is to block the migration and diffusion of pollutants in the soil by laying a barrier layer, so as to isolate the contaminated soil from the surrounding environment and achieve the purpose of contaminated land treatment. The in-situ soil barrier covering system is generally composed of a soil barrier system, a covering system, a monitoring system, etc. The soil barrier system is mainly composed of anti-seepage barrier materials such as HDPE membrane and mud wall. A barrier layer is built around the contaminated area to limit the contaminated area to a specific range; the soil covering system is usually composed of one or more layers of isolation such as clay layer and geomembrane; the monitoring system is mainly composed of monitoring wells upstream and downstream of the barrier area. Today's soil barrier covering remediation of contaminated soil has a large treatment area, which wastes a lot of land resources.

[0004] As disclosed in Patent No.: 202020061541.6, an in-situ barrier covering treatment device for contaminated soil and groundwater includes a contaminated soil layer and a covering treatment device arranged on the contaminated soil layer, a barrier layer is arranged between the covering treatment device and the contaminated soil layer, and the covering treatment device includes an outer shell, a blocking net is arranged at the inner bottom of the outer shell, an impermeable membrane is arranged on the top surface of the blocking net, a cultivated soil layer is arranged on the top surface of the impermeable membrane, a vegetation treatment layer is arranged on the cultivated soil layer, and a fertilization device is arranged in the cultivated soil layer. It prevents harmful substances in the contaminated soil from migrating to the cultivated soil layer by setting up an outer shell, and laying a barrier layer and an impermeable membrane at the bottom of the outer shell, so as to plant crops or plants on the cultivated soil layer, and cultivate or green the contaminated soil. It has the following disadvantages: 1) The connection stability between the outer shell and the soil is poor; 2) It is impossible to accurately inject water into the water inside the outer shell; 3) It is impossible to perform regional management.

In other words, the medicine injection pump is connected to the medicine injection component 5, so that the external fertilizer medicine is injected into the third cushion layer 4 in the form of liquid, so that the third cushion layer 4 maintains a certain fertility. Similarly, the pH regulator can be injected through the medicine injection pump to adjust the acid-base balance in the third cushion layer 4. In order to be able to operate accurately in each area, a number of electromagnetic control valves are provided on the medicine outlet end of the medicine injection component 5, and the electromagnetic control valves are used to control the on and off of the corresponding medicine outlet end;

[0051] See attached Figure 2-4 As shown, in some embodiments of the present application, the technical solution in the above embodiment is adopted, wherein a locking component 7 is further provided at the bottom of the frame component 3, and the locking component 7 is fixedly connected to the frame component 3;

[0052] The locking component 7 comprises:

[0053] The main body 701 is a columnar structure with a tapered bottom, a first sliding cavity 7011 is provided inside the main body 701, and a first opening is provided at the top of the first sliding cavity 7011;

[0054] The second sliding cavity 7012 is arranged in a ring array on the main body 701, and a limiting cavity 7013 is provided at the connection between the second sliding cavity 7012 and the first sliding cavity 7011. The second sliding cavity 7012 is arranged obliquely, and the two opposite second sliding cavities 7012 are arranged in a V shape;

[0055] The support component 702 is an annular structure, which is used to provide support and limit. The support component 702 is arranged in the first sliding cavity 7011, and is fixedly connected to the main body 701, and a first through hole is arranged at the center thereof;

[0056] The first sliding member 703 is a rod-shaped structure. The first sliding member 703 is arranged in the second sliding cavity 7012. One end of the first sliding member 703 extends into the first sliding cavity 7011. The first sliding member 703 is slidably connected to the main body 701. A stopper 7031 is arranged on the first sliding member. The stopper 7031 is located in the stopper cavity 7013. The first sliding member 703 can slide in the second sliding cavity 7012 and then extend outward from the second sliding cavity 7012 to contact the soil. At the same time, the stopper 7031 slides in the stopper cavity 7013.

[0057] The elastic component 704 is a spring, and the elastic component 704 is disposed in the limiting cavity 7013, one end of which is connected to the limiting member 7031, and the other end is connected to the inner wall of the limiting cavity 7013. When the limiting member 7031 moves in the limiting cavity 7013, the elastic component 704 is deformed. When closing is required, the first sliding member 703 is reset and slid in the second sliding cavity 7012 under the action of the elastic component 704.

[0058] The second sliding member 705 is a columnar structure, and is disposed in the first sliding cavity 7011, with one end of the second sliding member 705 being a conical hammer structure, and the other end of the second sliding member 705 passing through the first through hole, and being slidably connected to the supporting member 702;

[0059] In order to prevent the second sliding member 705 from rotating in the first sliding cavity 7011, the second sliding member 705 is provided with a limiting groove arranged in a ring array, and a protrusion is provided at the first through hole. The protrusion and the limiting groove are slidably connected, and a constraint is generated between the protrusion and the limiting groove so that the second sliding member 705 can only move longitudinally on the supporting member 702.

[0060] The bracket component 706 is a columnar frame structure, and the bracket component 706 is arranged on the supporting component 702. It is rotatably connected to the supporting component 702, and a third sliding cavity 7061 is arranged inside it, and a connecting hole is arranged on the top thereof (the connecting hole is a cross, a straight or a Poisson, etc.), and the third sliding cavity 7061 and the first sliding member 703 are threadedly connected.

[0061] It should be noted that the support component 702 divides the first sliding chamber 7011 into an upper chamber and a lower chamber, one end of the conical hammer of the first sliding member 703 is located in the lower chamber, and the other end passes through the support component 702 to the upper chamber, wherein the height of the bracket component 706 is less than the height of the upper chamber, and the bracket component 706 can rotate in the upper chamber, and during the rotation, the bottom of the bracket component 706 slides on the support component 702, and at the same time, the internal thread in the third sliding chamber 7061 inside it rotates synchronously.

[0062] Through the above technical solution, the technical solution generated in the embodiment of the present application is:

[0063] When in use, the starting piece passes through the first opening and is connected to the connecting hole at the top of the bracket component 706. The starting piece is rotated to rotate the bracket component 706. At the same time, the first sliding member 703 moves longitudinally under the action of the internal thread of the third sliding cavity 7061 and the constraint of the protrusion of the support component 702, prompting one end of the conical hammer of the first sliding member 703 to move upward, so that the second sliding member 705 moves outward. At the same time, the elastic component 704 sends deformation, and the second sliding member 705 forms a V-shaped rod structure after unfolding, so as to form a larger base area with the soil, thereby improving the stability of the connection. When it needs to be released, the starting piece is rotated in the opposite direction to make the first sliding member 703 move downward, and the second sliding member 705 is reset under the action of the elastic component 704. By adopting a mechanical structure, the operation is more convenient and the transmission efficiency is higher. By adopting a V-shaped second sliding member 705 to contact the soil, the connection stability of the frame component 3 is improved.

[0064] See attached Figure 5 As shown, in some embodiments of the present application, the technical solution in the above-mentioned embodiments is adopted, wherein a plurality of partition components 8 are provided inside the frame component 3, and the accommodating cavity is divided into a plurality of planting cavities arranged in a matrix by the partition components 8, the medicine outlet ends of the medicine injection components 5 are respectively located in each planting cavity, and the water outlet ends of the water injection components 6 are respectively arranged on the side walls of each planting cavity.

[0065] A first locking groove is provided on the frame part 3, and the first locking grooves are arranged in an array on the frame part 3. The partition part 8 is embedded in the first locking groove. The partition part 8 is composed of a plurality of spacers, and a second locking groove is provided on the spacer. Two adjacent spacers are embedded and connected through the second locking groove.

[0066] It should be noted that the number of planting cavities inside the frame component 3 is related to the number of partition components 8 and their arrangement relationship. The intersecting partition components 8 are connected by second clamping grooves. In order to meet the water demand of plants in different planting cavities, the corresponding partition height can be selected according to the water demand in the corresponding planting cavity, thereby forming planting cavities of different heights to meet the water demand of a variety of different plants without affecting each other.

[0067] In order to prevent the water in different planting cavities from communicating with each other, sealing members are provided in the second clamping grooves between the partition members 801 and the first clamping grooves between the partitions and the frame member 3, so as to construct different planting environments.

[0068] In order to further facilitate the adjustment of the planting area, different frame components 3 can be connected to each other by providing a connecting piece 301 (the connecting piece 301 is a U-shaped rod or an insert pin structure) on one side of the frame component 3 and a connecting groove 302 on the other side. Adjacent frame components 3 are connected through the connecting piece 301 and the connecting groove 302, and different frame components 3 are connected as a whole through the connecting piece 301 and the connecting groove 302.

[0069] Through the above technical solution, the technical effects produced in the embodiments of the present application are:

[0070] By adopting a split frame component 3 and partition component 8, it is not only easy to carry, but also the assembly is more convenient through the plug-in connection method. By adopting partitions of different heights, planting cavities of different heights can be formed to meet different planting needs. Through the plug-in connection between the connecting piece 301 and the connecting groove 302, the different frame components 3 can be integrated into one, thereby further improving the stability of the overall planting area.

[0071] See attached Figure 6As shown, in some embodiments of the present application, the technical solution in the above embodiments is adopted, wherein, in order to be able to adjust the water volume and pH according to actual conditions, a water level tank 303 is provided on one side of the frame component 3, and a third sliding member 304 (a rod-shaped structure) is provided in the water level tank 303, one end of the third sliding member 304 is slidably connected to the water level tank 303, and the other end is provided with a floating ball, and correspondingly, a distance detection sensor is provided on the top of the water level tank 303, and a pH detection sensor is provided in the third cushion layer 4. It should be noted that when there is no water on the surface of the third cushion layer 4, humidity detection sensors are scattered in the third cushion layer 4 to detect soil humidity; it is indispensable that it is also provided with a control system such as a PLC processor, a control terminal processor or a computer with a management APP installed, etc., which divides different pH standards, water level standards, and soil humidity standards for different planting areas through the control system, and the control system is connected The detection signals of the water level detection sensor, the humidity detection sensor and the pH detection sensor are collected and compared with the preset values. When the water level is lower than the preset value, the control system starts the electromagnetic valve of the water injection component 6 and / or the electromagnetic valve of the medicine injection component 5 in the corresponding planting cavity to adjust the water level; when the water level is higher than the preset value, the control system starts the electromagnetic valve of the water injection component 6 and / or the electromagnetic valve of the medicine injection component 5 in the corresponding planting cavity, and starts the water pump to connect with the water injection component 6 to reversely pump water, thereby lowering the water level. However, it should be noted that when there is no water on the third cushion layer 4, the humidity in the third cushion layer 4 is too high. The control system should start the early warning information and transmit it to the manager for processing. The processing method is as follows: spread sawdust, soil water-retaining agent, etc. on the third cushion layer 4. When the pH is adjusted, substances with different pH are injected through the medicine injection component 5 to adjust the soil to maintain the pH balance in the third cushion layer 4.

[0072] Through the above technical solution, the technical effects produced in the embodiments of the present application are:

[0073] By adding a water level groove 303 to the frame component 3 and moving the third sliding member 304 in the water level groove 303, the water level height is determined, and the humidity and pH of the soil are detected by the humidity detection sensor and the pH detection sensor, and in conjunction with the control system, the water injection component 6 and the drug injection component 5 are controlled to adjust the humidity and pH, so as to maintain the humidity and pH balance inside the third cushion layer 4, thereby achieving a real-time adjustment effect.

[0074] In some embodiments of the present application, the technical solution in the above embodiment is adopted. In order to further enhance the barrier effect on the contaminated soil, the first cushion layer 1 can be made of clay or a mixture of clay and crushed stone / biochar / sepiolite powder / magnesite powder. In order to treat the contaminated soil, a microbial passivation liquid can be used to passivate the contaminated soil. When clay is used, the thickness of the clay is 40-50 cm, and the permeability coefficient K of the clay is selected to be 1×10 - 7 cm / s-1×10 -6 cm / s, when the first cushion layer 1 is biochar, such as corn stalks or bamboo charcoal, it is mixed with clay as the first cushion layer 1, laid on the contaminated soil and then sprayed with a mixture of potassium permanganate, lanthanum nitrate and samarium nitrate, and then compacted by a compaction device before laying the second cushion layer 2.

[0075] The second cushion layer 2 is an impermeable membrane with a thickness of 6-8mm. The impermeable membrane adopts HDPE membrane or polyethylene geomembrane. The impermeable membrane has excellent waterproof performance on the one hand, and excellent puncture resistance on the other hand, which can resist most plant roots, thereby preventing the roots of crops planted in the upper cultivated soil layer from extending into the barrier layer, causing the clay in the barrier layer to harm the plants. In addition, laying the barrier membrane can also prevent the moisture and nutrients in the cultivated soil layer from leaking into the lower barrier layer, causing the cultivated soil layer to lose its water and fertilizer retention function.
