高松拍了幾張老井蓋的照片，其上“南京自來水廠”、“工務(wù)局”等繁體字樣特別醒目。為了防止參觀者過多對(duì)文物造成破壞，高松多了一個(gè)心眼：沒有公布井蓋的具體地址。事實(shí)上，這幾個(gè)老井蓋位于一家工廠的大門附近，如果不是有人指點(diǎn)，外人很難注意到它們有何特別之處。 </p> <p> 3個(gè)井蓋之中，兩個(gè)是正方形的，這區(qū)別于現(xiàn)今常見的圓形窨井蓋，井蓋一邊刻有3個(gè)“工務(wù)局”的繁體大字，表面滿滿交錯(cuò)排列著“二”的圖樣。因?yàn)槟甏眠h(yuǎn)，井蓋已被磨得光亮。另一個(gè)井蓋隸屬“南京自來水廠”所有，不過上面標(biāo)注的這幾字都是繁體，井蓋和現(xiàn)在常見的圓形窨井蓋類似，圖樣像一個(gè)向日葵圓盤。井蓋之上，和“南京自來水廠”的標(biāo)注相對(duì)，是“大管閘”3個(gè)大字，應(yīng)是顯示這個(gè)井蓋的用途。 </p><p> 在維修窨井蓋過程中，遵照快速維修更換，質(zhì)量牢固的原則，一般發(fā)現(xiàn)井蓋缺失、破損無特殊情況在2-4個(gè)小時(shí)左右完成維修，發(fā)現(xiàn)破損井蓋及時(shí)做好安全防護(hù)，維修后做好質(zhì)量防護(hù)。截止目前,市政所共維修更換雨、污水井蓋 36處，雨水柵 15處，發(fā)現(xiàn)并移交兄弟單位維修更換井蓋8處?？此撇黄鹧鄣男⌒【w，管理起來卻很不簡單。隨著縣城形象的日新月異，在管理細(xì)節(jié)方面，市政所一直在努力，井蓋雖小，但它卻是城市文明中一個(gè)不可或缺的元素，更是實(shí)實(shí)在在的民生大事。在采購窨井蓋需要注意什么問題嗎？</p><div style="width:100%;text-align:
