当电缆桥架遭遇“鼠军”偷袭，裸露的线缆如同战场上的伤兵，不仅威胁设备，更埋下火灾隐患。面对突如其来的破坏，与其斥巨资改造管线，不如用“土法炼钢”的智慧打响保卫战。以下三种低成本方案，助你快速筑起防鼠长城。

　　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：金属铠甲术——给桥架穿上“锁子甲”

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

　　老鼠的利齿能咬穿塑料桥架，却对金属网束手无策。采购孔径≤6mm的镀锌钢丝网，沿桥架外沿裁剪出“U型护甲”，用不锈钢扎带每隔10cm固定一道。加固桥架连接处和转弯角，这些区域常因缝隙过大成为鼠患突破口。若桥架已破损，可先用防火泥填充缺口，再覆盖钢丝网形成双重防护。此方案成本约5元/米，一名工人半天即可完成100米桥架加固。

　　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.

　　实施要点：

　　Implementation points:

　　钢丝网边缘需向内折叠1cm，避免锋利切口划伤线缆；

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

　　扎带锁扣必须朝向桥架外侧，防止被老鼠当作攀爬支点；

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

　　定期检查网面是否松动，建议每季度紧固一次。

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

　　方案二：气味结界——构建天然驱鼠屏障

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

　　老鼠的嗅觉灵敏度是人类的40倍，利用天然刺激性气味可打造无形的防护网。将薄荷精油与清水按1:20比例稀释，装入喷雾瓶沿桥架周边喷洒，形成50cm宽的“气味隔离带”。同步在桥架两端悬挂装满樟脑丸的纱布袋，利用挥发性气味驱赶鼠类。此方案单次成本不足30元，效果可持续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.

　　进阶技巧：

　　Advanced skills:

　　混合使用薄荷、桉树、辣椒提取物，增强气味复杂性；

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

　　在桥架底部铺撒石灰粉，既能吸湿防潮，又能通过碱性气味驱鼠；

　　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;

　　每周补充一次气味源，雨天后需立即补喷。

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

　　方案三：声波震慑——用“噪音”瓦解鼠军心理防线

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

　　超声波驱鼠器并非，但作为辅助手段可扰乱鼠类活动节律。选择频率在20kHz-35kHz之间的可调式设备，沿桥架走向每15米布置一台，高度距地面1.2米为宜。配合使用电磁驱鼠装置，通过电缆外皮释放特定频段电磁波，干扰老鼠神经系统。两套设备组合采购成本约200元，覆盖100米桥架。

　　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:

　　避免在人员密集区使用高频声波，可能引发不适；

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

　　电磁装置需与强电电缆保持30cm以上距离；

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

　　每月更换一次声波频率，防止老鼠产生适应性。

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

　　综合防御体系构建

　　Construction of comprehensive defense system

　　单一方案难以彻底解决问题，建议采用“物理阻隔+气味驱离+声波干扰”的三层防御：

　　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":

　　先用钢丝网封堵所有入口；

　　First, seal all entrances with steel wire mesh;

　　在桥架表面喷洒气味剂，悬挂驱鼠包；

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

　　关键节点布置声波设备，形成立体防护网。

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

　　日常维护同样关键：及时清理桥架周边杂物，封堵直径＞6mm的孔洞，在建筑外围设置30cm宽的碎石隔离带。记住，防鼠战没有一劳永逸，定期巡检与快速响应才是制胜法宝。当金属网反射着寒光，气味分子在空气中游走，超声波悄然织就天罗地网，鼠辈的突袭终将化为泡影。

　　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.
