style="font-size:14px;">力，國內(nèi)已有近200項通過各級鑒定的井蓋防盜成果，其中有幾十項系復合材料井蓋，有100多項系井蓋防盜裝置。</span> </p> <p> <span style="font-size:14px;">1、改變材質，井蓋被盜主要發(fā)生在鑄鐵井蓋上，不法分子主要看中了金屬井蓋的回收價值，加之不法回收站聯(lián)合“銷贓”，使得井蓋被盜屢禁不止?；谶@個原因人們嘗試用非金屬材料制造井蓋，如鋼纖維水泥井蓋、高分子復合材料井蓋、菱鎂井蓋等等，這也是這幾年的發(fā)展趨勢。非金屬井蓋不具備回收加之，確實起到了防盜作用。單也存在一些問題，非金屬井蓋的強度和材料對自然環(huán)境的適應，還有待驗證。這就使得非金屬井蓋的適用范圍受到限制。這方面還有待業(yè)界進一步研發(fā)。</span> </p> <p> <span style="font-size:14px;">2、在現(xiàn)有井蓋加裝防盜裝置，100多項井蓋防盜裝置，主要采用了六種方法：一為鐵鏈聯(lián)接法，二為鉸鏈聯(lián)接法，三為止口反旋技巧法，四為螺栓堵孔技巧法，五為鎖頭鑰匙法，六為撥叉關節(jié)聯(lián)動法。井蓋分為球墨鑄鐵井蓋、球墨井蓋、鑄鐵井蓋、高分子復合井蓋、防沉降井蓋、水泥井蓋、隱形井蓋、藝術井蓋、不銹鋼井蓋、五防井蓋、輕型井蓋、重型井蓋。</span>
