窨井蓋的本來功能，是屏蔽為維護(hù)地下管線而預(yù)留的方便工程人員出入的孔洞，這是其首要功能、根本功能。因此，在考慮提升窨井蓋的“人文品位”時(shí)，定是不可舍本求末，忘卻了窨井蓋的設(shè)置首先必須方便管理與維護(hù)。每一個(gè)窨井蓋都應(yīng)該準(zhǔn)確無誤地在醒目位置標(biāo)明類別，使管理者及維護(hù)人員在第1時(shí)間就明白這窨井蓋下的網(wǎng)管類別。 </p> <p> 正因如此，當(dāng)人們在為南京路步行街上鐫刻著經(jīng)典建筑、充盈著人文氣息的窨井蓋欣喜之時(shí)，也不得不遺憾它有未能恪盡職守之嫌，鄞州區(qū)窨井蓋多少錢，鄞州區(qū)窨井蓋多少錢，鄞州區(qū)窨井蓋多少錢。因?yàn)樵谶@些典雅的窨井蓋上恰恰缺失了功能標(biāo)識。日本和歐美國家的那些風(fēng)情各異的窨井蓋，并沒有因?yàn)樾涯康貥?biāo)明了功能字樣，令人感到有損形象。檢查窨井蓋的時(shí)候需要注意什么？鄞州區(qū)窨井蓋多少錢</p><div

普通混凝土是一種脆性材料。它的抗壓能力很強(qiáng)，抗拉能力卻很差。這是因?yàn)椋胀ɑ炷帘旧淼膹?qiáng)度很高，但在其內(nèi)部，尤其是砂石骨料與水泥漿體之間的過渡區(qū)內(nèi)存在許多的薄弱地帶，甚至微裂紋。在受到拉力時(shí)，這些微裂紋就會迅速擴(kuò)展，使得混凝土在遠(yuǎn)低于本身強(qiáng)度的拉力下便會斷裂。這種原理就類似于塑料包裝袋外面的豁口，沿著豁口一撕，堅(jiān)韌的包裝袋很輕易地就開了。因此，有些科學(xué)家剔除了混凝土中的普通砂子和石子，代之以極細(xì)的石英砂，并摻入較高活性的火山灰質(zhì)材料，制成活性粉末混凝土。鄞州區(qū)窨井蓋多少錢窨井蓋設(shè)計(jì)規(guī)范是什么樣的？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鄞州區(qū)窨井蓋多少錢,窨井蓋"

其一，這種井蓋工序少，人工成本省了下來；其二，它本身的強(qiáng)度高，只要很少的材料就能達(dá)到與普通混凝土相同的效果，因此非常節(jié)省材料；其三，它的耐腐蝕性能極強(qiáng)，一個(gè)井蓋可以用很久，這又降低了成本。后期算下來，用這種昂貴的材料做的井蓋反而劃算。重要的是，這種井蓋的內(nèi)部基本就沒有什么金屬，即使偷走了也不過是磐石一塊，真是一勞永逸地解決了井蓋被偷的問題。普通混凝土可以看作是膠凝材料將一些砂石骨料粘結(jié)在一起，砂石骨料本身是堅(jiān)固的，因此發(fā)生斷裂的地點(diǎn)通常在粘結(jié)的過渡區(qū)域。通常使用的普通混凝土強(qiáng)度約為40兆帕，為花崗巖的1/5。 </p><p> 歐美國家的窨井蓋千姿百態(tài)。在這些國家，窨井蓋扮演著多面手的角色：它們既擔(dān)負(fù)著提示及防護(hù)窨井出入口的傳統(tǒng)作用，又起著美化城市道路景觀的城市文化作用。城市里有許多一職多能的窨井蓋，窨井蓋上分別標(biāo)明“雨水”、“污水”、“上水”、“電信”等字樣，而且將一些指示公共設(shè)施、街區(qū)、景點(diǎn)等標(biāo)牌做在位于人行街道上的窨井蓋上，引導(dǎo)人們通往各自的目的地。在有些地方，甚至連“退役”的窨井，也被加以利用，被重新規(guī)劃設(shè)計(jì)，供人參觀，成為令人懷舊思故的城市景觀，讓市民和游客回味無窮。

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，是“大管閘”3個(gè)大字，應(yīng)是顯示這個(gè)井蓋的用途。窨井蓋的價(jià)格大概是多少？北侖區(qū)高纖維紋理圖窨井蓋哪個(gè)牌子好</p><p
