市政供水管網特點

　　1、施工范圍位(wei)于城市道路(lu)兩側，周圍臨近各類建筑物，車流(liu)和人流(liu)量較大。

　　2、管網(wang)所經地面上其(qi)他構筑物較(jiao)多，地下各種管線縱橫交錯，不確定(ding)性因素較(jiao)多，施工難度(du)較(jiao)大。

　　3、流經(jing)(jing)管網的自(zi)來水均經(jing)(jing)過加壓，各*供水管網的管徑和管網標高(gao)都不一致。

　　4、供(gong)水管網深埋地下，大多需溝槽開挖(wa)，安全隱患較多。

　　5、管(guan)網輸送的(de)自來水(shui)屬居民(min)生(sheng)活飲用水(shui)，為避免滲漏造(zao)成的(de)浪費和二次污染，對管(guan)網的(de)嚴密性要(yao)求較高。

　　6、供水管網(wang)工程為避免(mian)以后地面凹陷(xian)，施(shi)工中對(dui)回填土的(de)質量要求(qiu)較高。
