Description

Technical Field

[0001] The present invention relates to the technical field of termite control, and in particular to a soil-dwelling termite nest detection device and a soil-dwelling termite control method. Background Art

[0002] Soil-dwelling termites build nests, feed, and reproduce on the dam, expanding the main nest and creating secondary nests. The mushroom beds are scattered all over the dam, and the ant tunnels are connected in all directions. A complex nest and ant tunnel structure is formed in the dam, which destroys the structural integrity of the dam and the stability of the soil layer. It is very easy to induce leakage, pits and other dangerous situations, and even cause cross-dam breach and other accidents. Regardless of whether the ant colony in the nest is alive or not, the termite nests and ant tunnels in the dam are a serious threat to the safety of the dam. Detecting the location of the hidden nest and taking measures such as excavation or grouting to deal with it is a key way to solve the harm of termites. The earlier the treatment, the better.

[0061] Further optimized solution, the dual-axis moving mechanism includes an X-axis moving assembly and a Y-axis moving assembly, the X-axis moving assembly includes a second screw motor 9 and two second screw rods 10, the second screw motor 9 is installed on the movable base 1, and the two second screw rods 10 are installed side by side on the top surface of the movable base 1;

[0062] The second screw motor 9 is electrically connected to the control system 2, and the two second screw rods 10 are respectively connected to the output shaft of the second screw motor 9 through a transmission belt assembly.

[0068] The present invention also provides a method for controlling soil-dwelling termites, comprising the following steps:

[0069] Move the soil-dwelling termite nest detection device to the work area and fix the device on the ground by positioning the leg assembly;

[0070] Install the alloy drill bit 4 at the output end of the drilling machine 3;

[0071] Initial needle detection, the alloy drill bit 4 is inserted into the soil. During the drilling process, the torque sensor monitors the output torque of the lifting assembly, thereby monitoring the resistance change of the alloy drill bit 4 inserted into the soil; when the underground moisture is dry or the pressure is high, an electric hammer can be used as a power source, but the friction force during the needle detection process must be sensed and monitored in real time;

[0072] Pull out the alloy drill bit 4 and observe the material in the slot. If the material contains living termites, termite head shells or termite nest building materials, it is confirmed to be a living termite nest or an empty nest after extermination.

[0073] When the resistance change of the alloy drill bit 4 penetrating into the soil monitored by the torque sensor reaches a preset threshold, or there is an obvious sense of falling, it is confirmed to be a living termite nest or an empty nest after extermination; the resistance change reaches the preset threshold according to the actual use conditions, and is not specifically limited in this embodiment;

[0074] Continue to probe the location of the living termite nest or the empty nest after treatment to confirm the scope, depth and upper and lower boundaries of the ant nest;

[0075] Use an electric hammer to drive a drilling-type circular hollow drill bit to drill the location of a living termite nest or an empty nest after extermination; the outer diameter of the drilling-type circular hollow drill bit is 2.0 cm to 3.5 cm;

[0076] Use mud to pressurize and inject into the ant nest through the drilled hole, and fill the termite nest with mud through pressure; or use sulfuryl fluoride to fumigate and kill termites first, and then inject mud to complete the termite control;

[0077] If it is confirmed to be an ant nest, the drilling hole can be used to pressurize and inject mud into it, allowing the mud to fill the termite nest through pressure, and then be injected into other nest cavities through the main ant tunnel or larger ant tunnel to fill the ant nest. If it is a living nest, the mud pressure can be used to cover and fill the termite nest, and physical methods can be used to kill it; or sulfuryl fluoride can be used for fumigation and killing first;

[0078] In this way, the present invention monitors the resistance change through the torque sensor. When the resistance change of the alloy drill bit 4 penetrating into the soil reaches a preset threshold, it is preliminarily confirmed to be a living termite nest or an empty nest after extermination. Through further needle detection, the range, depth and upper and lower boundaries of the termite nest can be accurately determined, providing an accurate target position for subsequent treatment work.

[0079] For confirmed live termite nests or empty nests after extermination, the present invention adopts mud pressure injection or sulfuryl fluoride fumigation combined with mud injection for treatment, which effectively fills the ant nest, destroys the ant tunnel structure, and kills the remaining termites in the nest, thereby completely eliminating the threat of termites to the dam, effectively preventing the occurrence of dangerous situations such as dam leakage and collapse caused by termites, and ensuring the structural integrity and safety of the dam.

[0080] Further optimization of the scheme, before the preliminary needle exploration, also includes: determining the needle exploration and drilling locations through surface indicator materials of termite nests, potential danger areas discovered by geological radar, or concentrated areas of termite feeding activities; surface indicator materials include but are not limited to fly holes, Altissima, carbon rod mushrooms or antler mushrooms;

[0081] It also includes situations where full grouting of the dam is required.
