市政管道工程施工技術(shù)-全文預(yù)覽
【正文】 輸水管道是指從水源到城市水廠或者從城市水廠到相距較遠(yuǎn)管網(wǎng)的管道。（3） 泵站。從選定的水源（如江河、湖泊、深層地下水等）取水。關(guān)鍵詞：管道工程；管道開(kāi)槽施工；管道維護(hù)Municipal 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。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。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(kāi)槽施工，市政管道維護(hù)管理等內(nèi)容進(jìn)行闡述。（1） 取水構(gòu)筑物。這些構(gòu)筑物一般集中布置在水廠范圍內(nèi)。（4） 輸水管道。其功能是將來(lái)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。 給水管網(wǎng)的布置給水管網(wǎng)的布置原則：（1） 按照城市規(guī)劃平面圖布置管網(wǎng)，遠(yuǎn)近期結(jié)合，布置時(shí)應(yīng)考慮給水系統(tǒng)分期建設(shè)的可能性，并留有充分發(fā)展的余地。當(dāng)發(fā)生事故時(shí)，盡量不間斷供水或盡可能縮小斷水范圍。在同一供水區(qū)內(nèi)可布置若干條平行的干管，其間距可根據(jù)街區(qū)情況，采用5
