可肯定工作時間和空間先后次第，比較大限度節(jié)約資金。地下管道漏水檢測常用方法1、區(qū)域裝表法：指在供水管網(wǎng)的某一區(qū)域，將進入此區(qū)域的流量表與流出這一區(qū)域的流量表統(tǒng)計對照，其差額必是此區(qū)間的無計量損失，若無其它無計量消耗，則可知此區(qū)間的漏水損耗，這對管理者會“心中有數(shù)”。裝表分割區(qū)域愈密，分段愈清楚，則對各段漏水的情況了解也愈清楚。但是裝表不可能過于密集。這種方法不能確定漏水點準(zhǔn)確位置，故不能作為具體修復(fù)、破開路面的依據(jù)。要點：漏水引起計量差。2、聽音法、聲振法：聽音法指用某種傳聲工具傾聽漏水的聲音，根據(jù)漏水聲的大小與音質(zhì)特點來判斷漏水位置，從簡單的機械式聽漏棒到各類聽音測漏儀，這一方法從本質(zhì)上說應(yīng)叫聲振法。目前發(fā)展相當(dāng)迅速，是國內(nèi)外應(yīng)用的**為普遍而有效的方法，也是本手冊將重點介紹的方法。相關(guān)檢漏儀也應(yīng)屬于聲振法體系。要點：漏水引發(fā)振動和發(fā)聲效應(yīng)。3、紅外法：紅外熱成像檢測運用光電技術(shù)檢測物體熱輻射的紅外線特定波段信號，將該信號轉(zhuǎn)換成可供人類視覺分辨的圖像和圖形，在管網(wǎng)區(qū)域作紅外掃描測量，地下發(fā)生漏水時，局部地域與周圍產(chǎn)生溫度差，紅外輻射情況將不同。</p><div

能夠?qū)崟r對比不同拾音點位置上的音壓值，幫助技術(shù)人員判斷真正的漏水點。漏儀的使用特點：l調(diào)節(jié)濾波組合，將儀器設(shè)置到合適的濾波范圍內(nèi)；l調(diào)節(jié)儀器增益和音量，使耳機聽覺舒適；l在管道正上方按S型路徑沿管道進行探測，注意仔細(xì)分辨漏水噪聲異常；l發(fā)現(xiàn)異常區(qū)域應(yīng)多次反復(fù)測量，并對聲音的頻率和強度變化進行比較，直到確認(rèn)異常位置。l受環(huán)境噪聲影響，一般在夜間工作。在***的數(shù)字式動態(tài)降噪測漏儀信號處理技術(shù)和功能：l數(shù)字化濾波技術(shù)。l數(shù)字噪聲強度記錄。l前后多次檢測的有效值（或**小音壓值）比較記錄。l動態(tài)降噪技術(shù)選擇測漏儀款型時應(yīng)注意以下**基本的性能：1、穩(wěn)定性及耐用性；2、靈敏度和附加噪聲；3、音質(zhì)的真切感；4、頻率選擇和背景噪音的抗干擾性；5、攜帶操作的方便性；6、電池的工作時間長短；7、對本單位使用的適用性、經(jīng)濟性。靈敏度和附加噪聲：靈敏度既要相當(dāng)高又不是“愈高愈好”。這與使用者的要求有關(guān)，并且一般來講，一旦儀器的拾音器設(shè)計存在缺點，其靈敏度越高時儀器自帶的電子擾流聲也隨著增大。相對于設(shè)計優(yōu)良的拾音器，其靈敏度越高，同時拾取到的漏水異常音和背景噪音就會越多，因此這的確是一對矛盾。例如我國東北地區(qū)和南方地區(qū)。</p></p><br
