[0002] In the treatment of environmental pollution, the in-situ chemical oxidation remediation technology for contaminated soil has received extensive attention due to its high efficiency and low cost. This technology injects chemical oxidants into the contaminated soil, making them react with pollutants and converting them into harmless or low-toxic substances. However, existing in-situ chemical oxidation remediation methods often neglect the physical protection of the remediation area. Especially under harsh natural environmental conditions, such as strong winds and heavy rains, it is easy to cause a decline in the remediation effect and even damage the remediation area. The installation and disassembly processes of traditional covering materials are complex and require a large amount of manual operation, which not only increases the construction cost but also reduces the work efficiency. Therefore, an activated oxidation material covering structure for in-situ chemical oxidation remediation of contaminated soil is proposed. Content of the Utility Model

A contaminated soil main body is arranged on the lower side of the covering film, and an activated oxidation material for remediating soil through in-situ chemical oxidation is mixed inside the contaminated soil main body;

[0005] An insertion hole is opened on one side of the covering film, a limiting tube is inserted into the insertion hole, and a pH sensor and a temperature sensor are placed inside the limiting tube.

[0009] Preferably, a base is fixed to the bottom of the above-mentioned support rod, the bottom of the base is located on the top of the contaminated soil main body, and a limiting rod is fixed to the top of the support rod.

[0010] Preferably, a locking groove is formed on one side of the above-mentioned limiting rod, a sliding plate is slidably connected to the inner side of the sliding groove, and a locking rod inserted into the inner side of the locking groove is fixed to one side of the sliding plate.

[0011] Preferably, a pull rod is fixed to the side of the sliding plate away from the locking rod, a spring is sleeved on the outer side of the pull rod, and two ends of the spring are respectively connected to one side of the sliding plate and the sliding groove.

[0015] Second, by taking multiple connecting rods and support rods, aligning the limiting groove with the top of the limiting rod, after the limiting rod is inserted into the bottom of the limiting groove, releasing the pulling force on the pull rod, at this time, under the elastic force of the spring, the sliding plate is pushed to slide inside the sliding groove, so that the locking rod is inserted into the inner side of the locking groove. At this time, the installation of the support component of the covering film is completed. Using the combination of the connecting rod and the support rod, and the locking mechanism of the limiting groove and the support component, the installation of the covering film becomes fast and convenient, and it can also be easily realized during disassembly, which is convenient for subsequent maintenance and replacement.

[0032] Working principle: When the contaminated soil body 2 needs to be repaired, mix the activated oxidation material with the contaminated soil body 2, then insert the limiting tube 4 into the inside of the insertion hole 8, and then insert the pH sensor 5 and the temperature sensor 6 into the inside of the limiting tube 4 respectively, so that the pH sensor 5 and the temperature sensor 6 are located inside the contaminated soil body 2.

By directly inserting the pH sensor 5 and the temperature sensor 6 inside the contaminated soil body 2, the pH value and temperature changes of the soil during the repair process can be monitored in real time and accurately. Monitoring the data of the contaminated soil body 2 can timely adjust the repair plan to ensure that the chemical reaction proceeds under the best conditions, thereby improving the removal efficiency of pollutants and the repair speed.

[0033] When it is necessary to place the covering film 1 on the top of the main body 2 of the contaminated soil, only multiple connecting rods 71 and support rods 72 need to be taken at this time. A plurality of support rods 72 are fixed to one connecting rod 71, and the heights of the support rods 72 are different, so that the plurality of support rods 72 are positioned to form an arc. At this time, the connecting rods 71 are placed on the surface of the main body 2 of the contaminated soil according to the spacing, and then the limiting groove 78 is aligned with the top of the limiting rod 76, and then the arc-shaped bracket 713 and the connecting frame 77 are pressed downward, and at the same time, the pull rod 711 is pulled, so that the locking rod 74 leaves the inside of the limiting groove 78. When the limiting rod 76 is inserted into the bottom of the limiting groove 78, the pulling force of the pull rod 711 is released. At this time, under the elastic force of the spring 710, the sliding plate 712 is pushed to slide inside the sliding groove 79, so that the locking rod 74 is inserted into the locking groove 75. At this time, the installation of the support assembly 7 is completed. According to this method, the connecting frame 77 is connected to the support rod 72, and the installation of the support assembly 7 can be completed. The covering film 1 is covered on one side of the top of the plurality of arc-shaped brackets 713, and then around the main body 2 of the contaminated soil, the pressing rod 3 is used to press the covering film 1 on the top of the main body 2 of the contaminated soil. At this time, the installation of the covering film 1 is completed. Through the combination of the connecting rod 71 and the support rod 72, and the locking mechanism of the limiting groove 78 at the bottom of the covering film 1 and the support assembly 7, the installation of the covering film 1 becomes fast and convenient, and it can also be easily realized during disassembly, which is convenient for subsequent maintenance and replacement.

Roll up the covering film 1 from the top of the arc-shaped bracket 713, and pull the pull rod 711 to one side. At this time, the pull rod 711 drives the sliding plate 712 to slide inside the sliding groove 79, and at the same time, the locking rod 74 leaves the inside of the locking groove 75. At this time, the connection between the connecting frame 77 and the support rod 72 can be separated, and the plurality of connecting rods 71 and support rods 72 can be removed from the main body 2 of the contaminated soil. Then continue to roll up the covering film 1. When it is rolled to the insertion hole 8, take out the limiting tube 4, the pH sensor 5 and the temperature sensor 6. Finally, roll up the covering film 1 into a roll for convenient use of the covering film 1 next time.
