关于长寿区晏家片区市政污水管网工程
洪水影响评价报告审查意见的函
重庆乐至置业发展有限公司:
你司关于长寿区晏家片区市政污水管网工程洪水影响评价报告审查申请已收悉,我局组织专家对该项目的洪水影响评价报告进行了审查,审查意见如下:
一、长寿区晏家片区市政污水管网工程基本情况
工程位于晏家河晏家场镇段左岸,所在河段防洪评价标准为50年一遇。主要涉河建设内容包括污水管网及检查井。管道采用架空及埋设结合方式敷设。
(一)埋设管道
埋设段管道采用HDPE双壁波纹管进行敷设。管道及构筑物地基承载力不小于0.2MPa。沟槽在填方地段或沟槽超挖的,管道基础以下必须分层夯实回填,密实度不小于90%。对于地质条件较差地段,如淤泥、杂填土等,必须进行换填。换填材料根据具体情况分别采用符合要求的原土、砂砾石、砂性土等。管道及构筑物沟槽回填必须在混凝土及砂浆达到80%以上设计强度后方可进行,回填要求分层压实、对称均匀回填,密实度不小于90%。涉河段埋管长度2115.47m,其中,WS239~WS291段采用DN800钢管,长度1327.02m;WS291~WS292段采用DN800混凝土管,度47.41m;WS156~WS257、WS164~WS191、WS192~WS202段均采用DN400HDPE双壁波纹管,长度741.04m。
(二)架空管道
当管道设计高程高于现状地面时,采用桩基架空形式架空敷设,其中,WS157~WS164段、WS191~WS192段均采用DN400钢管架空敷设。架空支墩采用C30钢筋砼浇筑,支墩桩直径0.8m,桩长以嵌入中风化层2m控制,承台尺寸2.06×1.4×0.5m(L×B×H),支墩与钢管采用弧形钢板连接,钢板与钢管间满焊,钢板与锚固钢筋间采用围焊。涉河段架空管道长150.97m。
(三)检查井
管道交汇处、转弯处、管径或坡度改变处、跌水处以及直线管段上每隔一定距离设置检查井。当管道未沿着晏家河布置时,埋深小于5m采用砌块检查井,埋深大于等于5m采用深型钢筋混凝土深型检查井大样图;当管道沿晏家河布置时采用钢筋混凝土检查井(根据其深度选用普通或浅型井);桩基架空段采用架空检查井。涉河检查井共计90座。
