unicipal pipeline engineering construction technologyAbstract: municipal pipeline engineering is municipal engineering is an important part of urban survival and development are the foundation of urban lifeline. All kinds of municipal pipeline because its function is different, make its in material and accessories requirements, installation process and technical standards have bigger difference. However, municipal pipelineengineering are linear engineering, conditions, concrete engineering and the affiliated structure construction and mon in many aspects. This paper focuses on the role of of all kinds cop, position, decorate a method, the tube type and the advantages and disadvantages of each pipe, pipeline construction, municipal pipeline maintenance management content discussed in this paper. Keywords: pipeline engineering, Pipeline notching construction, pipeline maintenance1 管道工程 給水管道工程 給水管道系統(tǒng)的組成技術(shù)系統(tǒng)由取水、水質(zhì)處理、輸水和配水等設(shè)施以一定的方式組合而成的。然而,市政管道工程均為線型工程,在土石方、混凝土工程及附屬構(gòu)筑物施工方面又有許多共性。市政管道工程施工技術(shù)摘要:市政管道工程是市政工程的重要組成部分,是城市賴以生存和發(fā)展的物質(zhì)基礎(chǔ),是城市的生命線。各類市政管道由于其功能不同,使得其在材料及配件要求、安裝工藝和技術(shù)標(biāo)準(zhǔn)方面有較大的差異。本文主要對(duì)各類管線的作用、組成、布置方法,管材的種類及每種管材的優(yōu)缺點(diǎn),管道開槽施工,市政管道維護(hù)管理等內(nèi)容進(jìn)行闡述。它的主要任務(wù)是從水源取水,對(duì)水質(zhì)進(jìn)行處理,將符合要求的水質(zhì)輸送和分配到各用戶,滿足用戶對(duì)水質(zhì)、水壓、水量的要求。(1) 取水構(gòu)筑物。(2) 水處理構(gòu)筑物。這些構(gòu)筑物一般集中布置在水廠范圍內(nèi)。泵站是輸配水系統(tǒng)的加壓設(shè)施,有供水泵站和加壓泵站兩種形式。(4) 輸水管道。(5) 配水管網(wǎng)。其功能是將來自于較集中點(diǎn)(如輸水管渠的末端或貯水設(shè)施等)的水量分配輸送到整個(gè)供水區(qū)域,使用戶從近處接管用水。(6) 調(diào)節(jié)構(gòu)筑物。 給水管網(wǎng)的布置給水管網(wǎng)的布
