3、當(dāng)采用非金屬管材時，宜在充水浸泡24h后再進行滲水量測試。因混凝上管等管材在初充水時可吸收一定量的水，為準確計算滲水量可待吸水飽和后再測試。4、充水時應(yīng)打開排氣閥門，將管內(nèi)空氣排盡，暴露全部試驗段的管口。充水階段滲漏嚴重者應(yīng)馬上進行處理。5、記錄試驗水位及時間，計算滲水量（根據(jù)單位時間內(nèi)水位下降的高度和水箱的幾何尺寸計算）。對含酸堿等廢污水系統(tǒng)則不允許滲漏水。6、閉水合格后應(yīng)及時排空管內(nèi)的水，冬季施工時需采取防凍措施。7、閉水試驗完畢及時回填管溝，回填土在管頂上50以內(nèi)采用人工夯填，回填土不得夾有塊狀物。冬季施工時應(yīng)填暖土，管道周圍宜采用三七灰土夯填，填土層每次不宜超過50。8、管道系統(tǒng)中的構(gòu)筑物應(yīng)及時封井蓋，避免雜物掉入，堵塞管道。成都康泰市政管道總代理墊層材料有粒料和無機結(jié)合料穩(wěn)定土兩類。</p><div

市政管道工程是市政工程的重要組成部分，是城市重要的基礎(chǔ)工程設(shè)施。市政管道工程包括：給水管道、排水管道、燃氣管道、熱力管道、電力電纜。給水管道：主要為城市輸送供應(yīng)生活用水、生產(chǎn)用水、消防用水和市政綠化及噴灑用水，包括輸水管道和配水管網(wǎng)兩部分。排水管道：主要是及時收集城市生活污水、專工業(yè)廢水和雨水，并將生活污水和工業(yè)廢水輸送到污水處理廠進行處理后排放，雨水就近排放。以保證城市的環(huán)境衛(wèi)生和生命財產(chǎn)的安全。燃氣管道：主要是將燃氣分配站中的燃氣輸送分配到各用戶屬，供用戶使用。熱力管道：供給用戶取暖使用，有熱水管道和蒸汽管道。電力電纜：為城市輸送電能。按功能可分為動力電纜、照明電纜、電車電纜等；按電壓的高低可分為低壓電纜、高壓電纜和超高壓電纜。

2試驗程序在具備了閉水條件后，即可進行管道閉水試驗。試驗從上游往下游分段進行，上游實驗完畢后，可往下游充水，倒段試驗以節(jié)約用水。試驗各階段說明如下：1）注水浸泡：閉水試驗的水位，應(yīng)為試驗段上游管內(nèi)頂以上2米，將水灌至接近上由井口高度。注水過程應(yīng)檢查管堵、管道、井身，無漏水和嚴重滲水，在侵泡管和井1～2天進行閉水試驗；2）閉水試驗：將水灌至規(guī)定的水位，開始記錄，對滲水量的測定時間，不少于30分鐘，根據(jù)井內(nèi)水面的下降值計算滲水量，滲水量不超過規(guī)定的允許滲水量即為合格。3）試驗滲水量計算：滲水量試驗時間30分鐘時，每km管道每晝夜?jié)B水量為Q=（48q）＊（1000/L），式中Q---每km管道每d的滲水量q---閉水管道30分鐘的滲水量L---閉水管段長度當(dāng)Q≤允許滲水量時，試驗即為合格。區(qū)別在于：道路排水系統(tǒng)主要針對的是雨水，而市政排水系統(tǒng)主要針對的是城市污水。</p><div
