當電纜橋架遭遇“鼠軍”偷襲，裸露的線纜如同戰場上的傷兵，不僅威脅設備，更埋下火災隱患。面對突如其來的破壞，與其斥巨資改造管線，不如用“土法煉鋼”的智慧打響保衛戰。以下三種低成本方案，助你快速筑起防鼠長城。

　　When the cable tray is attacked by the "rat army", the exposed cables are like wounded soldiers on the battlefield, not only threatening equipment safety, but also burying fire hazards. In the face of sudden destruction, instead of investing heavily in pipeline renovation, it is better to use the wisdom of "homemade steelmaking" to launch a defensive battle. Here are three low-cost solutions to help you quickly build a Great Wall against rodents.

　　方案一：金屬鎧甲術——給橋架穿上“鎖子甲”

　　Option 1: Metal Armor Technique - Put "Lock Armor" on the bridge frame

　　老鼠的利齒能咬穿塑料橋架，卻對金屬網束手無策。采購孔徑≤6mm的鍍鋅鋼絲網，沿橋架外沿裁剪出“U型護甲”，用不銹鋼扎帶每隔10cm固定一道。加固橋架連接處和轉彎角，這些區域常因縫隙過大成為鼠患突破口。若橋架已破損，可先用防火泥填充缺口，再覆蓋鋼絲網形成雙重防護。此方案成本約5元/米，一名工人半天即可完成100米橋架加固。

　　The sharp teeth of mice can bite through plastic bridge frames, but they are powerless against metal mesh. Purchase galvanized steel wire mesh with aperture ≤ 6mm, cut out "U-shaped armor" along the outer edge of the bridge, and fix it with stainless steel zip ties every 10cm. Focus on reinforcing the connection points and turning angles of the bridge frame, which often become breakthrough points for rodent infestations due to large gaps. If the bridge is damaged, the gap can be filled with fireproof mud first, and then covered with steel wire mesh to form double protection. This plan costs about 5 yuan/meter, and one worker can complete the reinforcement of a 100 meter bridge in half a day.

　　實施要點：

　　Implementation points:

　　鋼絲網邊緣需向內折疊1cm，避免鋒利切口劃傷線纜；

　　The edge of the steel wire mesh should be folded inward by 1cm to avoid sharp cuts that may scratch the cable;

　　扎帶鎖扣必須朝向橋架外側，防止被老鼠當作攀爬支點；

　　The zip tie buckle must face the outside of the bridge to prevent it from being used as a climbing point by mice;

　　定期檢查網面是否松動，建議每季度緊固一次。

　　Regularly check if the mesh is loose, and it is recommended to tighten it once every quarter.

　　方案二：氣味結界——構建天然驅鼠屏障

　　Option 2: Odor Barrier - Building a Natural Rodent Repellent Barrier

　　老鼠的嗅覺靈敏度是人類的40倍，利用天然刺激性氣味可打造無形的防護網。將薄荷精油與清水按1:20比例稀釋，裝入噴霧瓶沿橋架周邊噴灑，形成50cm寬的“氣味隔離帶”。同步在橋架兩端懸掛裝滿樟腦丸的紗布袋，利用揮發性氣味驅趕鼠類。此方案單次成本不足30元，效果可持續2-3周。

　　The olfactory sensitivity of mice is 40 times that of humans, and they can create an invisible protective net by utilizing natural irritant odors. Dilute peppermint essential oil and water in the ratio of 1:20, put it into a spray bottle and spray it around the bridge to form a 50cm wide "odor isolation belt". Simultaneously hang gauze bags filled with camphor balls at both ends of the bridge, using volatile odors to drive away rodents. This plan has a single cost of less than 30 yuan and can last for 2-3 weeks.

　　進階技巧：

　　Advanced skills:

　　混合使用薄荷、桉樹、辣椒提取物，增強氣味復雜性；

　　Mixing mint, eucalyptus, and chili extracts to enhance odor complexity;

　　在橋架底部鋪撒石灰粉，既能吸濕防潮，又能通過堿性氣味驅鼠；

　　Spread lime powder at the bottom of the bridge frame, which can absorb moisture and prevent moisture, as well as drive away rodents through alkaline odors;

　　每周補充一次氣味源，雨天后需立即補噴。

　　Supplement the odor source once a week, and spray immediately after rainy days.

　　方案三：聲波震懾——用“噪音”瓦解鼠軍心理防線

　　Plan 3: Sound Wave Deterrence - Using "Noise" to Break Down the Psychological Defense Line of the Rat Army

　　超聲波驅鼠器并非，但作為輔助手段可擾亂鼠類活動節律。選擇頻率在20kHz-35kHz之間的可調式設備，沿橋架走向每15米布置一臺，高度距地面1.2米為宜。配合使用電磁驅鼠裝置，通過電纜外皮釋放特定頻段電磁波，干擾老鼠神經系統。兩套設備組合采購成本約200元，覆蓋100米橋架。

　　Ultrasonic rodent repellents are not omnipotent, but as an auxiliary means, they can disrupt the activity rhythm of rodents. Choose adjustable equipment with a frequency between 20kHz and 35kHz, and arrange one every 15 meters along the bridge, with a height of 1.2 meters above the ground. Cooperate with the use of electromagnetic rodent control devices to release specific frequency bands of electromagnetic waves through the cable sheath, interfering with the mouse nervous system. The combined procurement cost of two sets of equipment is about 200 yuan, covering a 100 meter bridge.

　　使用禁忌：

　　Usage taboos:

　　避免在人員密集區使用高頻聲波，可能引發不適；

　　Avoid using high-frequency sound waves in densely populated areas as it may cause discomfort;

　　電磁裝置需與強電電纜保持30cm以上距離；

　　Electromagnetic devices need to maintain a distance of at least 30cm from strong electrical cables;

　　每月更換一次聲波頻率，防止老鼠產生適應性。

　　Change the frequency of sound waves once a month to prevent mice from developing adaptability.

　　綜合防御體系構建

　　Construction of comprehensive defense system

　　單一方案難以徹底解決問題，建議采用“物理阻隔+氣味驅離+聲波干擾”的三層防御：

　　A single solution is difficult to completely solve the problem. It is recommended to adopt a three-layer defense of "physical barrier+odor removal+sound wave interference":

　　先用鋼絲網封堵所有入口；

　　First, seal all entrances with steel wire mesh;

　　在橋架表面噴灑氣味劑，懸掛驅鼠包；

　　Spray odorants on the surface of the bridge and hang rat repellent bags;

　　關鍵節點布置聲波設備，形成立體防護網。

　　Install sound wave equipment at key nodes to form a three-dimensional protective net.

　　日常維護同樣關鍵：及時清理橋架周邊雜物，封堵直徑＞6mm的孔洞，在建筑外圍設置30cm寬的碎石隔離帶。記住，防鼠戰沒有一勞永逸，定期巡檢與快速響應才是制勝法寶。當金屬網反射著寒光，氣味分子在空氣中游走，超聲波悄然織就天羅地網，鼠輩的突襲終將化為泡影。

　　Daily maintenance is equally crucial: timely cleaning of debris around the bridge, sealing of holes with a diameter greater than 6mm, and setting up a 30cm wide gravel isolation belt around the building perimeter. Remember, the battle against rodents is not a one-time solution. Regular inspections and quick responses are the key to victory. When the metal mesh reflects the cold light, odor molecules wander in the air, and ultrasound quietly weaves a trap, the sudden attack of mice will eventually turn into a bubble.
